Note Regarding Forward-Looking Statements

As used in this Annual Report on Form 10-K (this "Annual Report"), the terms the "Company," "Quantum," "we," "us," and "our" refer to Quantum Corporation and its subsidiaries taken as a whole, unless otherwise noted or unless the context indicates otherwise.

This Annual Report contains forward-looking statements. All statements contained in this report other than statements of historical fact, including, but not limited to, statements regarding our future operating results and financial position; our business strategy, focus and plans; our market growth and trends; our products, services and expected benefits thereof; and our objectives for future operations, are forward-looking statements. The words “believe,” “may,” “will,” “estimate,” “continue,” “anticipate,” “intend,” “expect,” “could,” “would,” “project,” “plan,” “potentially,” “preliminary,” “likely,” and similar expressions are intended to identify forward-looking statements. We have based these forward-looking statements largely on our current expectations and projections about future events and trends that we believe may affect our financial condition, results of operations, business strategy, short-term and long-term business operations and objectives, and financial needs. These forward-looking statements are subject to a number of risks, uncertainties, and assumptions, including the competitive pressures that we face; risks associated with executing our strategy; the impact of macroeconomic and geopolitical trends and events; the need to manage third-party suppliers and the distribution of our products and the delivery of our services effectively; the protection of our intellectual property assets, including intellectual property licensed from third parties; risks associated with our international operations; the development and transition of new products and services and the enhancement of existing products and services to meet customer needs; our response to emerging technological trends; the execution and performance of contracts by us and our suppliers, customers, clients and partners; the hiring and retention of key employees; risks associated with business combination and investment transactions; the execution, timing and results of any transformation or restructuring plans, including estimates and assumptions related to the cost and the anticipated benefits of the transformation and restructuring plans; the outcome of any claims and disputes; the ability to meet stock exchange continued listing standards; the possibility that the Nasdaq may delist our securities; our ability to remediate the material weaknesses in our internal control over financial reporting and to maintain effective internal control over financial reporting following remediation; risks related to changes in our management; and those risks described under Item 1A. Risk Factors. Moreover, we operate in a competitive and changing environment. New risks emerge from time to time. It is not possible for our management to predict all risks, nor can we assess the effect of all factors on our business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements we may make. In light of these risks, uncertainties, and assumptions, the future events and trends discussed in this report may not occur and actual results could differ materially and adversely from those anticipated or implied in the forward-looking statements. Accordingly, you should not rely on forward-looking statements as predictions of future events. Although we believe that the expectations reflected in the forward-looking statements are reasonable, we cannot guarantee that the future results, performance, or events and circumstances reflected in the forward-looking statements will be achieved or occur. We undertake no obligation to update any of these forward-looking statements for any reason after the date of this report or to conform these statements to actual results or revised expectations.

Summary of Risk Factors

Our business is subject to numerous risks and uncertainties, many of which are beyond our control. Some of the principal risks associated with our business include the following:

•We outsource our component supply, manufacturing, and service repair operations to third parties. Our business, financial condition, and operating results could face material adverse impacts if we cannot obtain parts, products, and services in a cost effective and timely manner that meets our customers’ expectations.

•Cost increases, supply disruptions, or raw material shortages, including in single source components, could harm our business.

•As a result of our global manufacturing and sales operations, we are subject to a variety of risks related to our business outside of the U.S., any of which could, individually or in the aggregate, have a material adverse effect on our business.

•Our stock price has experienced significant volatility in the past, and continued volatility may cause our common stock trading price to remain volatile or decline.

•Significant changes to our leadership team and management transitions might harm our future operating results.

•If we do not continue to meet all of the continued listing requirements of Nasdaq, we may be delisted.

•Our quarterly operating results have fluctuated significantly, and past results should not be used to predict future performance.

•If we do not successfully manage the changes that we have made and may continue to make to our business model, infrastructure, and management, our business could be disrupted, and that could adversely impact our operating results and financial condition.

•We have taken considerable steps towards reducing our cost structure. The steps we have taken may not reduce our cost structure to a level appropriate in relation to our future sales and therefore, these cost reductions may be insufficient to achieve profitability.

•Some of our products contain licensed, third-party technology that provides important product functionality and features. The loss or inability to obtain any such license could have a material adverse effect on our business.

•We have identified material weaknesses in our internal control over financial reporting, which could, if not properly remediated, result in additional material misstatements in our interim or annual consolidated financial statements, could impair our ability to produce accurate and timely financial statements and could adversely affect investor confidence in our financial reports, which could negatively affect our business.

PART I

ITEM 1. BUSINESS

Overview

Quantum delivers end-to-end data management solutions designed for unstructured data in the artificial intelligence ("AI") era. From high-performance ingest that powers AI applications and demanding data-intensive workloads to massive, durable data lakes to fuel AI models, Quantum delivers one of the most comprehensive and cost-efficient solutions for the entire data lifecycle. We specialize in solutions for video, images, audio, and other large files because this unstructured data represents more than 80% of all data being created according to leading industry analyst firms. Unstructured data poses both immense potential and significant challenges for organizations looking to retain and analyze their data for AI and other initiatives. Effectively managing and leveraging this data with an intelligent data management platform is not just an option but a necessity for businesses aiming to uncover hidden insights and create value. Unstructured data is exponentially larger than traditional corporate data, contains tremendous value, and must be captured, protected, and stored for many years, decades, and longer. It is no longer just about storing data— organizations need to extract value from their unique data to gain a competitive advantage. Locked inside video, imagery, security camera footage, scientific data sets, and other sensor-derived data is a wealth of information for informed decision-making.

Products and Services

Our portfolio of products includes primary storage software and systems, secondary storage software and systems, as well as devices and media.

Highly Performance Primary Storage Software and Systems include:

•StorNext Hybrid Flash/Disk File Storage Software: For video editing, post-production, and streaming applications, as well as large digital file archives.

•Unified Surveillance Platform Software: Unified compute and storage for video surveillance recording, storage, and analytics.

Highly Efficient Cost-per-Terabyte Secondary Storage Software and Systems include:

•ActiveScale Object Storage Software: Extremely scalable and durable storage for building massive data lakes, storage clouds, and cold archives.

•DXi Backup Appliances: Purpose-built backup appliances for high-speed backup and recovery and multisite data protection.

•Scalar Tape Storage: Low-cost, secure storage for long-term data archiving and offline data protection. Scalar tape storage systems are used by the world’s largest hyperscalers as well as thousands of enterprises worldwide.

CatDV Asset Management Software: For indexing, cataloging, AI data enrichment, and workflow orchestration, making data easily searchable and accessible so it can contribute to business insights.

Devices and Media includes the sale of standalone linear-tape open tape drives for small business data protection and archiving, and linear-tape open media for use in tape storage systems.

We also offer a broad portfolio of services including 24x7x365 global support, deployment and consulting services, education services, and Quantum-as-a-Service. Our services are delivered with a combination of expertise and technology, including the MyQuantum Service Delivery Platform, and Cloud-Based Analytics ("CBA") AIOps software for proactive remote monitoring.

Global Support and Services, and Warranty

Our global services strategy is an integral component of our total customer solution. Service is typically a significant purchase factor for customers considering long-term storage for archiving and retention or data protection storage solutions. Consequently, our ability to provide comprehensive installation and integration services as well as maintenance services can be a noteworthy competitive advantage to attract new customers and retain existing customers. In addition, we believe that our ability to retain long-term customer relationships and secure repeat business is frequently tied directly to our comprehensive service capabilities and performance.

Our extensive use of technology and innovative product intelligence allows us to scale our global services operations to meet the needs of our customers. We are currently able to provide service to customers in more than 100 countries, supported by 24-hour, multi-language technical support centers located in North America, Europe, and Asia. We provide our customers with warranty coverage on our products. Customers with high availability requirements may also purchase additional services to obtain faster response times on our high-performance shared storage systems, tape systems, and disk backup systems. We offer this additional support coverage at a variety of response levels up to 24-hours a day, seven-days-a-week, 365-days-a-year, for customers with stringent high-availability needs. We provide support ranging from repair and replacement to 24-hour rapid exchange to on-site service support for our midrange and enterprise-class products. In addition to these traditional installation and maintenance services, we also provide project management, managed services, and other value-added services to enhance our customer’s experience and engagement. These incremental services create a deeper relationship with customers that enables them to maximize the value of our solution and better positions us to retain our customers through technology transitions.

We generally warrant our hardware products against defects for periods ranging from one to three years from the date of sale. We provide warranty and non-warranty repair services through our service team and third-party service providers. In addition, we utilize various other third-party service providers throughout the world to perform repair and warranty services for us to reach additional geographic areas and industries to provide quality services in a cost-effective manner.

Research and Development

We are a solutions company that relies on technology advancements to compete in an industry characterized by rapid change and evolving customer requirements. Our success depends, in part, on our ability to introduce new products and features to meet end user needs. Our research and development teams are focused on technology and services to make our end-to-end solution of storage systems and data management software easier to manage at scale, software enhancements to make our storage more searchable and accessible, software-defined hyperconverged storage technology, next generation solid-state and hard-drive storage system software, data deduplication and other data reduction technologies, and making tape and other mediums even more efficient as a solution for medium for long term archival storage.

Sales and Distribution Channels

Product Sales Channels

We utilize distributors, value-added resellers ("VARs") and direct market resellers ("DMRs") in our sales process. Our reseller program provides our channel partners the option of purchasing products directly or through distribution channels and provides them access to a more comprehensive product line. Additionally, we sell directly to multiple large corporate entities and government agencies.

OEM Relationships

We sell our products to several original equipment manufacturer ("OEM") customers that resell our hardware products under their own brand names and typically assume responsibility for product sales, end user service and support. We also license our software to certain OEM customers that include this software in their own brand name products. These OEM relationships enable us to reach end users not served by our branded distribution channels or our direct sales force. They also allow us to sell to select geographic or vertical markets where specific OEMs have exceptional strength.

Customers

Table of Contents

We provide solutions to multiple industries globally. Historically, our primary customers are in hyperscale, technology and industrial, media and entertainment, federal government, life sciences and healthcare, and financial industries. In addition, we sell to OEMs, distributors, VARs and DMRs to reach end user customers. Sales to our top five customers represented 27% and 21% of revenue in fiscal 2026 and fiscal 2025, respectively, of which one customer represented more than 10% of total fiscal 2026 revenue and none of our customers represented 10% or more of our total fiscal 2025 revenue.

Competition

The markets in which we participate are highly competitive, characterized by rapid technological change and changing customer requirements. In some cases, our competitors in one market area are customers or suppliers in another. Our competitors often have greater financial, technical, manufacturing, marketing, or other resources than we do. Additionally, the competitive landscape continues to change due to merger and acquisition activity as well as new entrants into the market.

As our customers look to use both public and private cloud storage services, these options offer a competitive alternative, as well as new platforms and new ways to deploy our software. We expect that the data storage infrastructures of the future will be both hybrid-cloud and multi-cloud, meaning our customers will store their data in the various large public cloud environments, and also want to use services from multiple public cloud vendors, and also evaluate private cloud solutions.

Our primary storage solutions, including object storage systems, primarily face competition from the EMC business unit of Dell Inc. (“Dell”), International Business Machines Corporation, (“IBM”), NetApp, Inc., and other enterprise storage vendors in the markets we serve.

Our secondary storage solutions, primarily tape storage systems, compete in the midrange and enterprise reseller and end user markets with IBM and other tape library vendors. Competitors for entry-level and OEM tape systems include BDT Products, Inc. and several others that supply or manufacture similar products. In addition, disk backup products and cloud storage are an indirect competitive alternative to tape storage. Our backup storage systems primarily compete with products sold by Dell, Hewlett Packard Enterprise Company and Veritas Technologies LLC.

Manufacturing and Supply Chain

Quantum has a global supply chain and operations organization, with contract manufacturers located in the U.S. and Mexico along with supporting third-party logistics companies in the Europe, Middle East, and Africa region (“EMEA”), and the Asia-Pacific region, or (“APAC”). Our supply chain and manufacturing strategy minimizes geo-political and environmental causal risks and provides flexibility to support demand fluctuations by region.

Quantum primary storage and secondary disk-based storage systems are sold as appliances that combine Quantum software with servers that are procured from various server vendors. Quantum sources these servers from various vendors, then uses contract manufacturers for final integration and shipment to customers. Quantum's tape storage systems are designed by Quantum and manufactured by a global contract manufacturer.

Tape media is manufactured in Japan and distributed globally.

The global supply chain and logistics have been severely constrained and impacted by inflationary pricing for the past couple of years as well as import tariffs in the current year. While we are cautiously optimistic and see signs of improvement over the past year with supply of both server and tape automation components, we continue to experience some constraints. While some components continue to have extended lead times and often non-cancellable purchase orders are required, Quantum continues to work with suppliers to minimize lead times and associated liabilities. We continue to focus on a number of actions including alternate component qualifications, more aggressive management of contract manufacturers, and model changes for better logistics performance and visibility.

Intellectual Property and Technology

We generally rely on patent, copyright, trademark and trade secret laws and contract rights to establish and maintain our proprietary rights in our technology and products. As of March 31, 2026, we hold 166 U.S. patents. In general, these patents have a 20-year term from the first effective filing date for each patent. We may also hold

Table of Contents

foreign patents and patent applications for certain of our products and technologies. Although we believe that our patents and applications have significant value, rapidly changing technology in our industry means that our future success may also depend heavily on the technical competence and creative skills of our employees.

From time to time, third parties have asserted that the manufacture and sale of our products have infringed on their patents. We are not knowingly infringing any third-party patents. Should it ultimately be determined that licenses for third-party patents are required, we will undertake best efforts to obtain such licenses on commercially reasonable terms. See Note 10: Commitments and Contingencies for additional disclosures regarding lawsuits alleging patent infringement.

On occasion, we have entered into various patent licensing and cross-licensing agreements with other companies. We may enter into patent cross-licensing agreements with other third parties in the future as part of our normal business activities. These agreements, when and if entered into, would enable these third parties to use certain patents we own and enable us to use certain patents owned by these third parties. We have also sold certain patents, retaining a royalty-free license for these patents.

We are a member of the consortium that develops, patents, and licenses linear-tape open, technology to media manufacturing companies. We receive royalty payments for linear-tape open media technology sold under licensing agreements. We have also entered into various licensing agreements with respect to our technology, patents and similar intellectual property which provide licensing revenues in certain cases and may expand the market for products and solutions using these technologies.

Segment Information

We operate as a single reporting unit and operating segment for business and operating purposes. Information about revenue attributable to each of our product groups is included in Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations and information about revenue and long-lived assets attributable to certain geographic regions is included in Note 12 : Segment Information and Note 3 : Balance Sheet Information, respectively, to the consolidated financial statements and risks attendant to our foreign operations is set forth below in Item 1A. Risk Factors.

Seasonality

We generally have the greatest demand for our products and services in the fourth quarter of each calendar year, or our fiscal third quarter. We usually experience the lowest demand for our products and services in the second quarter of each calendar year, or our fiscal first quarter.

Human Capital

In the fiscal year ended March 31, 2026, our Vice President of Corporate Affairs lead our human capital initiatives, which include the design and execution of all people strategies. The Vice President of Corporate Affairs worked directly with the Board of Directors, the Leadership and Compensation Committee, and Senior Management on the design, cost, and effectiveness of our people programs to ensure they are competitive and reward our teams for driving company performance.

Our workforce is currently distributed across 18 countries, with approximately 490 employees globally as of March 31, 2026, including 231 in North America, 133 in APAC, and 126 in EMEA. We engage with contractors, consultants, or temporary employees as needs for special projects occur.

Work Environment

We intend to design, evaluate, and expand our total rewards programs so they are competitive in attracting, motivating, rewarding, and retaining key talent.

We have a mix of office-based and remote employees. We work to ensure our office environments, whether at a primary location or remote, are safe, professional, and inclusive so our employees can be successful.

To build high performing products and services, we aim to build high performing teams that are inclusive, diverse, and respected regardless of gender, race, color, religion, age, sexual orientation, or disability. We invest in multiple hiring and training initiatives, performance and professional development opportunities, and candidates ranging from interns to experienced leaders.

We believe that fostering an inclusive work environment is a critical component for our culture of excellence.

Culture of Integrity, Ownership, and Urgency

Our company goals and leadership attributes set the tone for our culture of integrity, ownership, and urgency. Employees are empowered to ask questions and encouraged to report concerns without fear of retaliation, including reporting anonymously if preferred.

During the fiscal year ended March 31, 2026, we redesigned our internal employee recognition program to encourage exemplifying integrity, ownership, and urgency and provided training focused on those expectations. We also continued our practice of “no internal meeting days” so employees can have more time for focused work, training, or personal development.

Talent Development

Our talent is our greatest asset. We seek to actively grow our employees’ skills and leadership perspective while retaining our most critical talent. Our managers and employees participate in periodic performance discussions that help facilitate conversations on employee contributions, goals, and expectations.

ITEM 1A. RISK FACTORS

Investing in our common stock involves a high degree of risk. Before you make a decision to buy our common stock, in addition to the risks and uncertainties discussed above under “Note Regarding Forward-Looking Statements,” you should carefully consider the risks set forth herein. If any of these risks actually occur, it may materially harm our business, financial condition, liquidity and results of operations. As a result, the market price of our common stock could decline, and you could lose all or part of your investment. Additionally, the risks and uncertainties described in this Annual Report are not the only risks and uncertainties that we face. Additional risks and uncertainties not presently known to us or that we currently believe to be immaterial may become material and adversely affect our business.

Risks Related to Our Supply Chain, Customers and Sales Strategy

Cost increases, supply disruptions, or raw material shortages, including in single source components, could harm our business.

We have and may continue to experience cost increases or supply interruptions in raw materials and components necessary for our products, as well as increased freight charges and reduced capacity from our freight forwarders. Any such increases or interruptions could materially negatively impact our business, prospects, financial condition and operating results, including delays in manufacturing and shipments of our products and in some cases, result in canceled orders. While we have implemented price increases intended to offset rising costs, we cannot provide assurance that these increases will have the desired effects on our business model in the expected timeframe.

We outsource our component supply, manufacturing, and service repair operations to third parties. Our business, financial condition, and operating results could face material adverse impacts if we cannot obtain parts, products, and services in a cost effective and timely manner that meets our customers’ expectations.

Many aspects of our supply chain and operational results are dependent on the performance of third-party business partners, including contract manufacturers, service providers, and product integrators. We face a number of risks as a result of these relationships, any or all of which could have a material adverse effect on our business and harm our operating results and financial condition. For the years ended March 31, 2026 and 2025, the same two vendors represented more than 10% of total expenses.

Dependence on a single contract manufacturer and logistics provider

We currently rely on a single contract manufacturer to manufacture our products and to provide warehousing and logistics services for our spare parts. As a result, we are exposed to risks associated with concentrating these functions with a single provider, including potential disruptions in manufacturing, inventory management, warehousing and product delivery.

If our contract manufacturer is unable or fails to meet our production, quality, delivery, warehousing or logistics requirements, or otherwise experiences operational or financial difficulties, capacity constraints, natural disasters, severe weather events, fires, power outages or other disruptions affecting its manufacturing, warehousing or logistics operations, our ability to manufacture and deliver products, provide spare parts and support our customers could be adversely affected. If it becomes necessary to transition to a different contract manufacturer or logistics provider, such transition could be time-consuming and costly and could result in delays, increased expenses and operational disruptions. Any such events could adversely affect our business, results of operations and financial condition.

Sole source of product supply

In many cases, our business partners are the sole source of supply for the products or parts they manufacture, or the services they provide to us, and we do not have executed long-term purchase agreements with these partners. Our reliance on a limited number of suppliers and the lack of any guaranteed sources of supply exposes us to several risks, including:

•the inability to obtain an adequate supply of key components;

•the inability to control delivery schedules;

•price volatility for the components of our products;

•failure of a supplier to meet our quality or production requirements;

•failure of a supplier of key components to remain in business or adjust to market conditions; and

Table of Contents

•consolidation among suppliers, resulting in some suppliers exiting the industry, discontinuing the manufacture of components or increasing the price of components.

We cannot assure investors that we will be able to obtain a sufficient supply of these key components or that their costs will not increase. If our component supply is disrupted or delayed, or if we need to replace our existing suppliers or redesign a product to accept different components, we cannot guarantee that additional components will be available when required, on terms that are favorable to us, or at reasonable prices, which could extend our lead times and increase our component costs.

Cost and purchase commitments and processes

We may not be able to control the costs of products or services we obtain from our business partners. We provide a customer demand forecast used to procure inventory to build our products. We could be responsible for the financial impact from any forecast reduction or product mix shift relative to materials already purchased under a prior forecast, including the cost of finished goods in excess of current customer demand or for excess or obsolete inventory.

In some cases, we may retain the responsibility to purchase component inventory to support third-party manufacturing activities, which presents a number of risks that could materially and adversely affect our financial condition. For instance, as part of our component planning, we may place orders with or pay certain suppliers for components in advance of receiving customer purchase orders. We may occasionally enter into large orders with vendors to ensure that we have sufficient components for our products to meet anticipated customer demand. It is possible that we could experience a design or manufacturing flaw that could delay or even prevent the production of the components for which we previously committed to pay.

In addition, in order to reduce manufacturing lead times and plan for adequate component supply, from time to time we may issue non-cancelable and non-returnable component or product orders. Our inventory management systems and related supply chain visibility tools may be inadequate to enable us to make accurate forecasts and effectively manage our component and product supply. If we ultimately determine that we have excess supply, we may have to reduce our prices and write down or write off excess or obsolete inventory. Alternatively, insufficient supply levels may lead to shortages resulting in delayed or lost revenue or reduced product margins. We could experience operating losses based on any of these conditions.

We also maintain service parts inventories to satisfy future warranty obligations and to earn service revenue by providing enhanced and extended technical support and product service during and beyond the warranty period. We estimate service parts inventory needs based on historical usage and forecasts of future warranty and service contract requirements, including estimates of failure rates, costs to repair, and out of warranty revenue. Given the significant levels of judgment inherently involved in the process, we cannot provide assurance that we will be able to maintain service parts inventories appropriate to satisfy customer needs or to avoid inventory purchases that later prove to be unnecessary. If we are unable to maintain appropriate levels of service parts inventories, our business, financial condition and results of operations may be materially and adversely impacted.

Although we have contracts for most of our third-party repair service vendors, the contract period may not be the same as the underlying customer service contract. In such cases, we face risks that the third-party service provider may increase the cost of providing services in later periods already under contract to our customers at a fixed price.

Financial condition and stability

Our third-party business partners may suffer adverse financial or operating results or be negatively impacted by economic conditions. We may face interrupted component, product, or service supply as a result of financial or other volatility affecting our supply chain. As a result, we could suffer production downtime or increased costs to procure alternate products or services.

Quality and supplier conduct

We have limited control over the quality of products and components produced and services provided by our third-party business partners and their supply chains. The quality of the products, parts or services may not be acceptable to our customers and could result in customer dissatisfaction, lost revenue, and increased warranty costs. In addition, we have limited control over the manner in which our business partners conduct their business. We may face negative consequences or publicity as a result of a third-party’s failure to comply with applicable compliance, trade, environmental, or employment regulations.

Table of Contents

As a result of our global manufacturing and sales operations, we are subject to a variety of risks related to our business outside of the U.S., any of which could, individually or in the aggregate, have a material adverse effect on our business.

A significant portion of our manufacturing, sales, and supply chain operations occur in countries other than the U.S. We utilize third-party business partners to engineer, produce, sell, and fulfill orders for our products, several of which have operations located in foreign countries including China, Hungary, India, Japan, Malaysia, Singapore, Mexico, the Philippines, Thailand, and Ukraine. Because of these global operations, we are subject to a number of risks in addition to those already described, including:

•increasing import and export duties and value-added taxes, or trade regulation changes, including tariffs, that could erode our profit margins or delay or restrict our ability to transport our products;

•war, military conflict, and geopolitical unrest, including the conflicts in Iran and the Middle East and between Russia and Ukraine and Israel and Hamas, may affect our engineering and support teams outside the U.S. and their ability to perform as well as our sales and services delivery with sanctioned entities and countries;

•reduced or limited protection of our intellectual property;

•difficulty complying with multiple and potentially conflicting regulatory requirements and practices, including laws governing corporate conduct outside the U.S., such as the Foreign Corrupt Practices Act, United Kingdom Bribery Act, and similar regulations;

•commercial laws that favor local businesses and cultural differences that affect how we conduct business;

•differing technology standards or customer requirements;

•exposure to economic uncertainty and fluctuations including inflation, adverse movement of foreign currencies against the U.S. dollar (the currency in which we report our results), restrictions on transferring funds between countries, and continuing sovereign debt risks;

•fluctuations in freight costs, limitations on shipping and receiving capacity, and other disruptions in the transportation and shipping infrastructure at important geographic points for our products and shipments;

•inflexible employee contracts and employment laws that may make it difficult to terminate or change the compensation structure for employees in the event of business downturns;

•difficulties attracting and recruiting employees and wage inflation in highly competitive markets;

•political instability, military, social and infrastructure risks, especially in emerging or developing economies;

•political or nationalist sentiment impacting global trade, including the willingness of non-U.S. consumers to purchase goods or services from U.S. corporations;

•natural disasters, including earthquakes, flooding, typhoons and tsunamis; and

•pandemics and epidemics, and varying and potentially inconsistent governmental restrictions on the operation of businesses, travel and other restrictions.

Any or all of these risks could have a material adverse effect on our business.

We rely on indirect sales channels to market and sell our branded products. The loss of or deterioration in our relationship with one or more of our resellers or distributors, or our inability to establish new indirect sales channels to drive growth of our branded revenue, could negatively affect our operating results.

We sell most of our branded products to distributors, value added resellers, and direct market resellers, who in turn sell our products to end users. We use different distribution channel partners in different countries and regions in the world. The success of these sales channels is hard to predict, particularly over time, and we have no purchase commitments or long-term orders from them that assure us of any baseline sales. Several of our channel partners carry competing product lines, which they may promote over ours. A channel partner might discontinue our products or fail to effectively market them, and each partner determines the type and amount of our products that it will purchase and the price at which it sells to end users. Establishing new indirect sales channels is an important part of our strategy to drive growth of our branded revenue. Our results of operations could be adversely affected by any number of factors related to our channel partners, including:

•a change in competitive strategy that adversely affects a partner’s willingness or ability to distribute our products;

•the reduction, delay, or cancellation of orders or the return of significant products volume;

Table of Contents

•our inability to gain traction in developing new indirect sales channels for our branded products, or the loss of one or more existing partners; or

•changes in requirements or programs that allow our products to be sold by third parties to government or other customers.

Because we rely heavily on channel partners to market and sell our products, if one or more of them were to experience a significant deterioration in its financial condition or its relationship with us, this could disrupt our product distribution and reduce our revenue, which could materially and adversely affect our business, financial condition, and operating results.

We heavily utilize channel partners to perform the functions necessary to market and sell our products in certain product and geographic segments. To fulfill this role, partners must maintain an acceptable level of financial stability, creditworthiness, and the ability to successfully manage business relationships with the customers they serve directly. If partners are unable to perform in an acceptable manner, we may be required to reduce sales to the partner or terminate the relationship. We may also incur financial losses for product returns from partners or for the failure or refusal of distributors to pay obligations owed to us. Either scenario could result in fewer of our products being available to the affected market segments, reduced levels of customer satisfaction and increased expenses, which could in turn have a material and adverse impact on our business, results of operations and financial condition.

A certain percentage of our sales are to a few customers, some of which are also competitors, and these customers generally have no minimum or long-term purchase commitments. The loss of, or a significant reduction in demand from, one or more key customers could materially and adversely affect our business, financial condition and results of operations.

Our product sales have been and continue to be concentrated among a small number of channel partners, direct end users, and original equipment manufacturers. We sell to many end user customers and channel partners on purchase orders, not under the terms of a binding long-term procurement agreement. Accordingly, they generally are not obligated to purchase any minimum product volume, and our relationships with them are terminable at will. In addition, we have focused our direct-sales business on the largest users of hierarchical storage architectures, the so-called “hyperscalers”; there are very few of these extremely large storage customers, but their order activity has a significant impact on our results from quarter to quarter.

Some of our tape and disk products are incorporated into larger storage systems or solutions that are marketed and sold to end users by third parties. Because of this, we may have limited market access to those end users, limiting our ability to influence and forecast their future purchasing decisions. In addition, revenue from OEM customers has decreased in recent years. Certain of our large OEM customers are also our competitors, and could decide to reduce or terminate purchasing our products for competitive reasons.

In addition, our sales efforts may involve long sales cycles during which we incur expenses to educate our customers about product use and benefits and support customer-driven product evaluations. These cycles may make it difficult for us to predict when, or if, future sales will occur.

During the fiscal year ended March 31, 2026, one customer represented more than 10% of our total revenue and during the fiscal year ended March 31, 2025, no customer represented 10% or more of our total revenue. If any of our large customers should significantly decrease or stop purchasing our solutions, we would see a significant reduction in revenue that may result in a material adverse effect on our operating results.

The U.S. federal government is an important customer, and our business may be materially and adversely harmed by changes in government purchasing activity.

A portion of our sales are to various agencies and departments of the U.S. federal government, and federal spending funding cuts and temporary government shutdowns have previously impacted and may continue to impact our revenue in the future. Future spending cuts by the U.S. federal government, temporary shutdowns of the U.S. federal government, or changes in its procurement processes or criteria could decrease our sales to the federal government and materially and adversely affect our operating results. In addition, changes in government certification requirements applicable to our products could impact our ability to sell to U.S. federal customers.

Risks Related to Our Operating Results, Financial Condition, or Stock Price

Table of Contents

We continue to face risks related to inflation, economic uncertainty, and slow economic growth.

Uncertainty about economic conditions poses risks as businesses may further reduce or postpone spending in response to reduced budgets, tightening of credit markets, increases in inflation and interest rates, negative financial news, and declines in income or asset values which could adversely affect our business, financial condition and operating results. Recent inflationary increases have driven up the prices at which we are able to purchase necessary components, products, and services, as well as the cost of contract labor. In addition, we continue to face risks related to uncertain tariff levels between countries where our products are manufactured and sold, unstable political and economic conditions, including conflicts in Iran and the Middle East, the war between Russia and Ukraine, and the Hamas-Israel conflict, and concerns about sovereign debt, which could negatively impact the U.S. and global economies and adversely affect our financial results. In addition, our ability to access capital markets may be restricted or result in unfavorable financing terms, impacting our ability to react to changing economic and business conditions and could also materially and adversely affect our ability to sustain our operations at their current levels.

Our stock price has experienced significant volatility in the past, and continued volatility may cause our common stock trading price to remain volatile or decline.

Our stock price has been extremely volatile in the past. For example, the closing price of our common stock on the Nasdaq Global Market ranged from $4.31 to $13.35 from June 1, 2025 through May 31, 2026. During this time, we did not experience any material changes in our financial condition or results of operations that would explain such price volatility. The trading price of our common stock may continue to fluctuate in response to a number of events and factors, many of which may be beyond our control, such as:

•quarterly variations in our operating results;

•failure to meet our financial guidance or the expectations of securities analysts and investors;

•new products, services, innovations, strategic developments, or business combinations and investments by our competitors or us;

•changes in our capital structure, including incurring new debt, issuing additional debt or equity to the public, and issuing common stock upon exercise of our outstanding warrants or subscribing to our recent rights offering;

•large or sudden purchases or sales of stock by investors;

•changes in interest and exchange rates;

•market volatility resulting from a public health emergency;

•fluctuations in the stock market in general and market prices for technology companies in particular;

•tariffs imposed by the U.S. government on sales originating in or being shipped to countries with which we have on-going trade or other political conflicts;

•investigations or enforcement actions related to a potential or actual failure to comply with applicable regulations;

•costs of new or ongoing commercial litigation; and

•significant changes in our brand or reputation.

Any of these events and factors may cause our stock price to rise or fall and may adversely affect our business and financing opportunities.

Significant changes to our leadership team and management transitions might harm our future operating results.

We experienced significant changes to our leadership team in fiscal 2026, including changes to our Chief Executive Officer, Chief Financial Officer, Chief Revenue Officer and Chief Administrative Officer. Although we believe these leadership transitions are in the best interest of our stockholders, these transitions may result in the loss of personnel with deep institutional knowledge. Further, the transition could potentially disrupt our operations and relationships with employees, suppliers, partners, and customers due to added costs, operational inefficiencies, decreased employee morale and productivity and increased turnover. We must successfully recruit and integrate our new leadership team members within our organization to achieve our operating objectives. As such, the leadership transition may temporarily affect our business performance and results of operations while the new members of our leadership team become familiar with our business and acclimate into their new roles. Furthermore, these changes increase our dependency on the other members of our leadership team that remain with us, who are

Table of Contents

not contractually obligated to remain employed with us and may leave at any time. Any such departure could be particularly disruptive given that we are already experiencing leadership transitions and, to the extent we experience additional management turnover, competition for top management is high such that it may take some time to find candidates that meet our requirements. Our future operating results may depend upon the continued service of our key personnel and in significant part upon our ability to attract and retain qualified management personnel. If we are unable to mitigate these or other similar risks, our business, results of operations and financial condition may be materially and adversely affected.

We may be unable to attract and retain key talent necessary to effectively meet our business objectives.

The market for skilled engineering, sales, and administrative talent is competitive and we have seen delays in recruiting and hiring timeframes. We believe our ability to recruit and hire new talent, and retain existing key personnel, may be negatively impacted by prior and ongoing fluctuations in our operating results, stock price, and ability to offer competitive benefits and total compensation programs. Our business results may be harmed if we are unable to attract and retain key talent in the future.

Our quarterly operating results have fluctuated significantly, and past results should not be used to predict future performance.

Our quarterly operating results have fluctuated significantly in the past and could fluctuate significantly in the future. As a result, our quarterly operating results should not be used to predict future performance. Quarterly results could be materially and adversely affected by a number of factors, including, but not limited to:

•supply chain constraints or other failures by our contract manufacturers to complete shipments in a timely manner;

•customers canceling, reducing, deferring, or rescheduling significant orders as a result of excess inventory levels, weak economic conditions, reduced demand, or other factors;

•IT spending fluctuations resulting from economic conditions or changes in U.S. federal government spending;

•new product announcements by us or our competitors which may cause purchasing delays or cancellations;

•seasonality, including customer and government fiscal year-ends and budget availability impacting demand for our products;

•reduced demand, declines in large orders, royalty or software revenues, or other changes in product mix;

•product development and ramp cycle delays or product performance or quality issues;

•poor execution of and performance against expected sales and marketing plans and strategies;

•increased competition which may, among other things, increase pricing pressure or reduce sales;

•restructuring actions or unexpected costs; and

•foreign currency exchange fluctuations.

Our operating results depend on continuing and increasing market acceptance of our existing products and on new product introductions, which may be unsuccessful, in which case our business, financial condition and results of operations may be materially and adversely affected.

A limited number of products comprise a significant majority of our sales, and due to rapid technological change in our industry, our future operating results depend on our ability to improve existing products and develop and successfully introduce new products. We have devoted and expect to continue to devote considerable management and financial resources to these efforts.

When we introduce new products to the market, they may not achieve market acceptance or significant market share. In addition, the target markets for our new products may not continue or grow as we anticipate. Our new products may not be successfully or timely qualified by new customers, and if they are qualified, we may not achieve high volume production in a timely manner, if at all. In addition, we may experience technical, quality, performance-related, or other difficulties that could prevent or delay the introduction and market acceptance of new products.

If we are not successful in timely completing our new product qualifications and ramping sales to our key customers, our revenue and operating results could be adversely impacted. In addition, if the quality of our products is not

Table of Contents

acceptable to our customers, customer dissatisfaction, lost revenue, and increased warranty and repair costs could result.

We derive significant revenue from products incorporating tape technology. Our future operating results depend in part on continued market acceptance and use of tape products; in the past, decreases in the tape products market have materially and adversely impacted our business, financial condition and operating results.

We currently derive significant revenue from products that incorporate some form of tape technology, and we expect to continue to do so in the next several years. As a result, our future operating results depend in part on continued market acceptance and use of tape products. Decreased market acceptance or use of products employing tape technology has materially and adversely impacted our business, financial condition, and operating results, and we expect that our revenues from certain types of tape products could continue to decline in the future.

Disk, solid-state, and flash storage products, as well as various software solutions and alternative technologies, have eroded the demand for tape products. We expect that, over time, many of our tape customers could migrate toward these other products and solutions and their proportionate contribution to our revenue will increase in the future. While we are making targeted investments in software, disk backup and flash storage systems, and other alternative technologies, these markets are characterized by rapid innovation, evolving customer demands, and strong competition, including competition with companies who are also significant customers. If we are not successful in our efforts, we may not be able to attract or retain customers, and our business, financial condition and results of operations could be materially and adversely affected.

A significant decline in our media royalty or branded software revenues could materially and adversely affect our business, financial condition and operating results.

Our media royalties and branded software revenues generate relatively greater profit margins than some of our other products and can significantly impact our overall profitability. We receive media royalty revenue based on tape media cartridges sold by various tape media manufacturers and resellers. Under our patent and technology license agreements with these companies, each of the licensees determines the pricing and number of units of tape media cartridges that it sells. Our media royalty revenue varies based on the licensees’ media sales and other factors, including:

•our customers’ continued use of storage tape media, including the size of the installed base of devices and similar products that use tape media cartridges;

•the relative growth in units of newer device products, since the associated media cartridges for newer products typically sell at higher prices compared with the media cartridges associated with older products;

•media consumption habits and rates of end users and pattern of device retirements;

•the level of channel inventories; and

•agreement on standards for newer generations of the tape media that generates our royalty revenue.

Risks Related to Our Business and Industry

If we do not successfully manage the changes that we have made and may continue to make to our business model, infrastructure, and management, our business could be disrupted, and that could adversely impact our operating results and financial condition.

Managing change is an important focus for us. In recent years, we have implemented several significant initiatives involving our sales and marketing, product engineering, and operations organizations, aimed at transitioning our revenue model from discrete hardware sales to recurring software revenue, increasing our efficiency, and better aligning internal operations with our corporate strategy. In addition, we have reduced headcount to streamline and consolidate our supporting functions as appropriate following recent acquisitions and in response to market or competitive conditions, and have increased our reliance on certain third-party business relationships. If we are unable to successfully manage the changes that we implement and detect and address issues as they arise, our business could be disrupted, and our results of operations and financial condition could be materially and adversely impacted.

In addition, given that we are relatively new to offering products and services on a subscription basis, and those models in the storage industry continue to evolve, we may not be able to effectively compete, drive expected

Table of Contents

revenue and margin growth, or obtain profitability for the foreseeable future. Demand for subscription-based products could also erode one-time sales of our hardware products that might not be immediately offset by increased recurring revenue.

We have taken considerable steps towards reducing our cost structure. The steps we have taken may not reduce our cost structure to a level appropriate in relation to our future sales and therefore, these cost reductions may be insufficient to achieve profitability.

In the last several years, we have recorded significant restructuring charges and made cash payments to reduce our cost of sales and operating expenses to respond to adverse economic and industry conditions, to execute strategic management decisions, and to rationalize our operations following acquisitions. These restructuring plans may result in decreases to our revenues or adversely affect our ability to grow our business in the future. Workforce reductions may also adversely affect employee morale and our ability to retain our employees, and may result in increased legal proceedings by terminated employees. We may take future steps to further reduce our operating costs, including additional restructurings in response to strategic decisions, increased operating and product costs due to inflation, supply chain constraints, and other external factors, adverse changes in our business or industry, or future acquisitions. We may be unable to reduce our cost of sales and operating expenses at a rate and to a level appropriate in relation to our future sales, which may materially and adversely affect our business, financial condition and results of operations.Conversely, if our cost-reduction initiatives are more extensive than necessary or result in the reduction of critical personnel or resources, they could impair our ability to execute our business strategy, support customers, develop products, respond to market opportunities, or otherwise operate effectively, which could adversely affect our business, financial condition and results of operations.

In addition, our ability to achieve the anticipated cost savings and other benefits from these restructuring plans within the expected time frame is subject to many estimates and assumptions which may be adversely impacted by significant economic, competitive and other uncertainties, some of which are beyond our control. If these estimates and assumptions are incorrect, if we experience delays, or if other unforeseen events occur, our business, financial condition, and operating results could be adversely affected.

The failure to successfully integrate future acquired businesses, products or technologies could harm our business, financial condition, and operating results.

As a part of our business strategy, we have in the past and may make acquisitions in the future. We may also make significant investments in complementary companies, products or technologies. If we fail to successfully integrate such acquisitions or significant investments, it could harm our business, financial condition, and operating results. Risks that we may face in our efforts to integrate any recent or future acquisitions include, among others:

•failure to realize anticipated synergies or return on investment from the acquisition;

•difficulties assimilating and retaining employees, business culture incompatibility, or resistance to change;

•diverting management’s attention from ongoing business concerns;

•coordinating geographically separate organizations and infrastructure operations in a rapid and efficient manner;

•the potential inability to maximize our financial and strategic position through the successful incorporation of acquired technology and rights into our products and services;

•failure of acquired technology or products to provide anticipated revenue or margin contribution;

•insufficient revenues to offset increased expenses associated with the acquisition;

•costs and delays in implementing or integrating common systems and procedures;

•reduction or loss of customer orders due to the potential for market confusion, hesitation and delay;

•impairment of existing customer, supplier and strategic relationships of either company;

•insufficient cash flows from operations to fund the working capital and investment requirements;

•difficulties in entering markets in which we have no or limited direct prior experience and where competitors in such markets have stronger market positions;

•dissatisfaction or performance problems with the acquired company;

•the assumption of risks, unknown liabilities, or other unanticipated adverse circumstances of the acquired company that are difficult to quantify; and

•the cost associated with the acquisition, including restructuring actions, which may require cash payments that, if large enough, could materially and adversely affect our liquidity.

A cybersecurity breach could adversely affect our ability to conduct our business, harm our reputation, expose us to significant liability, or otherwise damage our financial results.

We maintain sensitive data on our own systems related to our employees, strategic partners, and customers, including personally identifiable information, intellectual property, and proprietary business information. In addition, many of our customers and partners store sensitive data on our products.

It is critical to our business that our employees’, strategic partners’ and customers’ sensitive information remains and is perceived as secure. While we employ sophisticated security measures in our own environment and our product features, we may face internal and external threats including unauthorized access, ransomware attacks, security breaches, and other system disruptions. A cybersecurity breach of our own IT infrastructure or products sold to our customers could result in unauthorized access to, loss of, or unauthorized disclosure of such information and expose us to litigation, indemnity obligations, government investigations, and other possible liabilities. Additionally, a cyber-attack, whether actual or perceived, could result in negative publicity which could harm our reputation and reduce our customers’ confidence in the effectiveness of our solutions, which could materially and adversely affect our business and operating results. A breach could also expose us to increased costs from remediation, disruption of operations, or increased cybersecurity protection costs that may have a material adverse effect on our business. Although we maintain cybersecurity liability insurance, our insurance may not cover all or any portion of claims of these types, or may not be adequate to indemnify us for inability that may be imposed. Any imposition or liability or litigation costs that are not covered by insurance could harm our business.

If our products fail to meet our or our customers’ specifications for quality and reliability, we may face liability and reputational or financial harm which may adversely impact our operating results and our competitive position may suffer.

We may from time to time experience problems with the performance of our products, which could result in one or more of the following:

•increased costs related to fulfilling our warranty obligations;

•reduced, delayed, or cancelled orders or the return of a significant amount of products; or

•the loss of reputation in the market and customer goodwill.

These factors could cause our business, financial condition and results of operations to be materially and adversely affected.

In addition, we face potential liability for product performance problems because our end users employ our technologies to store and backup important data and to satisfy regulatory requirements. Loss of this data could cost our customers significant amounts of money, directly and indirectly as a result of lost revenues, intellectual property, proprietary business information, or other harm to their business. In some cases, the failure of our products may be caused by third-party technology that we incorporate into them. Even if failures are caused by third-party technology, we may be required to expend resources to address the failure and preserve customer relationships.

We could also potentially face claims for product liability from our customers if our products cause property damage or bodily injury. Although there are limitations of liability in our commercial agreements and we maintain technology errors and omissions liability and general liability insurance, our insurance may not cover potential claims of these types, or may not be adequate to indemnify us for all liability that may be imposed. Any imposition of liability or litigation costs that are not covered by insurance or could harm our business.

Competition is intense in the data storage and protection market in which we operate.

Our competitors in the data storage and protection market are aggressively trying to advance and develop new technologies and products to compete against us. Consequently, we face the risk that customers could choose competitor products over ours. As a result of competition and new technology standards, our sales or gross margins could decline, which could materially and adversely affect our business, financial condition, and operating results.

Some of those competitors are much larger and financially stronger, have more diverse product offerings, and aggressively compete based on their reputations and greater size.

Table of Contents

Technological developments, industry consolidation, and storage market competition over the years have resulted in decreased prices and increased commoditization for tape device and automation products and our other product offerings. Pricing pressure is more pronounced for entry-level products and less pronounced for enterprise products.

Over time, the prices of our and competitor products have decreased, but such products often incorporate new or different features and technologies from what we offered in prior years. We face risks that customers could choose competitors’ products over ours due to these features and technologies or pricing differences. If competition further intensifies, our product sales and gross margins could decline, which could materially and adversely affect our business, financial condition and results of operations.

Additional industry consolidation may further result in:

•competitors consolidating, having greater resources and becoming more competitive with us;

•new entrants into one or more of our primary markets increasing competition;

•customers that are also competitors becoming more competitive with us and/or reducing their purchase of our products;

•competitors acquiring our current suppliers or business partners and negatively impacting our business model; and

•market uncertainty and disruption due to the impact and timing of announced and completed transactions.

Risks Related to Intellectual Property

Some of our products contain licensed, third-party technology that provides important product functionality and features. The loss or inability to obtain any such license could have a material adverse effect on our business.

Certain of our products contain technology licensed from third parties that provides important product functionality and features. We cannot provide assurance that we will have continued access to this technology in the future. In some cases, we may seek to enforce our technology access via litigation against the licensing company itself, which may cause us to incur significant legal or other costs and may not be resolved in our favor. Other legal actions against the licensing company, such as for intellectual property infringement, could also impact our future access to the technology. We also have limited visibility or control of the technology roadmap at the licensing company and cannot ensure that the licensing company will advance the roadmap of the licensed technology in the manner best for us. We also face the risk of not being able to quickly implement a replacement technology or otherwise mitigate the risks associated with not having access to this licensed technology. Any of these actions could negatively impact our available technology portfolio, thereby reducing the functionality or features of our products, and could materially and adversely affect our business, financial condition, and operating results.

Third-party intellectual property infringement claims could result in substantial liability and significant costs, and, as a result, our business, financial condition and results of operations may be materially and adversely affected.

From time to time, third parties allege that our products infringe their patented or proprietary technology and demand that we purchase a license from them. The ultimate outcome of any license discussion or litigation is uncertain. Adverse resolution of any third-party infringement claim could subject us to substantial liabilities and require us to refrain from manufacturing and selling certain products. In addition, the costs incurred in intellectual property litigation can be substantial, regardless of the outcome. As a result, our business, financial condition, and operating result could be materially and adversely affected.

If we fail to protect our intellectual property or if others use our proprietary technology without authorization, our competitive position may suffer.

Our future success and ability to compete depends in part on our proprietary technology. We rely on a combination of copyright, patent, trademark, and trade secrets laws and nondisclosure agreements to establish and protect our proprietary technology. However, we cannot provide assurance that patents will be issued with respect to pending or future patent applications that we have filed or plan to file, that our patents will be upheld as valid, or that our patents will prevent the development of competitive products, or that any actions we have taken will adequately protect our intellectual property rights.

Despite our efforts to protect our proprietary rights, unauthorized parties may attempt to copy or otherwise obtain or use our products or technology. Enforcing our intellectual property rights can sometimes only be accomplished through litigation, which is expensive and can divert management’s attention away from our business. In addition, the laws of some foreign countries do not protect our proprietary rights to the same extent as the laws of the U.S.

We license certain of our software under “open source” licenses. Because of the characteristics of open source software licenses, it may be relatively easy for competitors, some of whom have greater resources than we have, to enter our markets and compete with us. In addition, our failure to comply with the terms of open source licenses could have a material adverse effect on our competitive position and financial results.

One of the characteristics of open source software is that the source code is typically publicly available at no charge, and anyone who obtains copies has a license under certain of our intellectual property rights. Depending on the license, that may include access to certain of our patents, to modify and redistribute the software, and use it to compete in the marketplace. Certain open source software licenses require users to license to other any software that is based on, incorporates, or interacts with the open source software. Although we endeavor to comply fully with those requirements, third parties could claim we are required to license larger portions of our software than we intended. If such claims were successful, they could adversely impact our competitive position and financial results by providing our competitors with access to sensitive information that may help them develop competitive products without the degree of overhead and lead time required by traditional proprietary software development.

It is possible for competitors to use our open source project software to develop their own software, potentially reducing the demand for our solution and putting price pressure on our subscription offerings. We cannot guarantee that competitive pressure or the availability of new open source software will not result in price reductions, reduced operating margins and loss of market share, any one of which could harm our business, financial condition, operating results, and cash flows.

In addition, we use our own open source project software in our proprietary products. As a result, there is a risk that we may inadvertently release as an open source certain code that was intended to be kept as proprietary, that reveals confidential information regarding the inner workings of our proprietary products, or that could enable competitors to more readily reverse engineer or replicate aspects of our proprietary technology that we would otherwise protect as trade secrets. We may also accept contributions from third parties to our open source projects, and it may be difficult for us to accurately determine the origin of the contributions and whether their use, including in our proprietary products, infringes, misappropriates, or violates third-party intellectual property or other rights. The availability of certain of our own software in source code form may also enable others to detect and exploit security vulnerabilities in our products. In addition, our use of open source software may harm our business and subject us to intellectual property claims, litigation, or proceedings in the future.

Risks Related to Regulatory Matters

We are subject to many laws and regulations, and violation of or changes in those requirements could materially and adversely affect our business.

We are subject to numerous U.S. and international laws and requirements regarding corporate conduct, fair competition, corruption prevention, data protection and security, import and export practices, and hazardous or restricted material use, storage, discharge, and disposal, including laws applicable to U.S. government contractors. We have incurred, and will continue to incur, costs and business process changes to comply with such regulations. While we maintain a rigorous corporate ethics and compliance program, we may be subject to increased regulatory scrutiny, significant monetary fines or penalties, suspension of business opportunities, loss of jurisdictional operating rights, and increased litigation and investigation costs as a result of any failure to comply with those requirements. If we identify that we have fallen out of compliance, we may proactively take corrective actions, including the filing of voluntary self-disclosure statements with applicable agencies, which could cause us to incur additional expenses and subject us to penalties and other consequences that could adversely affect our business, financial condition, and operating results. Our supply and distribution models may be reliant upon the actions of our third-party business partners and we may also be exposed to potential liability resulting from their violation of these or other compliance requirements. Further, our U.S. and international business models are based on currently applicable regulatory requirements and exceptions. Changes in those requirements or exceptions could necessitate changes to our business model. Any of these consequences could materially and adversely impact our business and results of operations.

Our actual or perceived failure to adequately protect personally identifiable information could adversely affect our business, financial condition, and operating results.

Table of Contents

A variety of state, national, foreign, and international laws and regulations apply to the collection, use, retention, protection, disclosure, transfer, deletion, and other processing of personally identifiable information. These privacy- and data protection-related laws and regulations are evolving, with new or modified laws and regulations proposed and implemented frequently and existing laws and regulations subject to new or different interpretations.

Compliance with these laws and regulations can be costly and can delay or impede the development or implementation of new products or internal systems. Failure to comply could result in enforcement actions and significant penalties against us, which could result in negative publicity, increase our operating costs, and have a material adverse effect on our business, financial condition, and operating results.

Risks Related to Being a Public Company

We incur significant costs as a result of operating as a public company, and our management devotes substantial time to complying with public company regulations.

As a public company, we are obligated to file with the SEC annual and quarterly reports and other reports that are specified in Section 13 and other sections of the Securities Exchange Act of 1934, as amended (the "Exchange Act"). We are also required to ensure that we have the ability to prepare financial statements that are fully compliant with all SEC reporting requirements on a timely basis. In addition, we are and will continue to become subject to other reporting and corporate governance requirements, including certain requirements of Nasdaq, and certain provisions of Section 404 of the Sarbanes-Oxley Act of 2002 (“SOX Act”) and the regulations promulgated thereunder, which will impose significant compliance obligations upon us.

Section 404 of the SOX Act, as well as rules subsequently implemented by the SEC and Nasdaq, have imposed increased regulation and disclosure and required enhanced corporate governance practices of public companies. We are committed to maintaining high standards of corporate governance and public disclosure, and our efforts to comply with evolving laws, regulations and standards in this regard are likely to result in increased selling, general, and administrative expenses and a diversion of management’s time and attention from revenue-generating activities to compliance activities. These changes will require a significant commitment of additional resources. We may not be successful in implementing these requirements and implementing them could materially and adversely affect our business, results of operations and financial condition. In addition, if we fail to implement the requirements with respect to our internal accounting and audit functions, our ability to report our operating results on a timely and accurate basis could be impaired. If we do not implement such requirements in a timely manner or with adequate compliance, we might be subject to sanctions or investigation by regulatory authorities, such as the SEC and Nasdaq. Any such action could harm our reputation and the confidence of investors and customers in us and could materially and adversely affect our business and cause our share price to fall.

If we do not continue to meet all of the continued listing requirements of Nasdaq, we may be delisted.

The listing of our common stock on the Nasdaq Global Market is contingent on our compliance with the Nasdaq Global Market’s rules for continued listing.

On September 20, 2023, we received a deficiency notice from the Nasdaq Listing Qualifications Department (the “Nasdaq Staff”) notifying us that we were not in compliance with Nasdaq’s minimum closing bid price requirement of $1.00 per share for 30 consecutive business days, as set forth in Nasdaq Listing Rule 5450(a)(1) (the “Minimum Bid Price Requirement”). We did not regain compliance with the Minimum Bid Price Requirement within 180 days from the initial deficiency notice, and on March 19, 2024, we were notified by the Nasdaq Staff that we would be delisted unless we timely request a hearing before a Nasdaq hearings panel (the “Panel”).

We were also notified on November 14, 2023 and February 13, 2024 that we were not in compliance with Nasdaq Listing Rule 5250(c)(1) (the “Filings Requirement”) as a result of our failure to timely file the Quarterly Reports on Form 10-Q for the fiscal quarters ended September 30, 2023 and December 31, 2023. The Nasdaq Staff initially gave us until May 7, 2024 to regain compliance with the Filings Requirement.

On May 14, 2024, we had a hearing before the Panel to address the deficiencies in complying with the Minimum Bid Price Requirement and the Filings Requirement and to present a plan to regain compliance. On June 6, 2024, the Panel issued a ruling granting us an extension period for (i) the Minimum Bid Price Requirement until September 16, 2024 and (ii) the Filings Requirement until July 1, 2024. As a result of the filing of the Annual Report on Form 10-K for the fiscal year ended March 31, 2024 on June 28, 2024, which included the financial statements and other information required in the Quarterly Reports on Form 10-Q for the fiscal quarters ended December 31, 2023 and

Table of Contents

September 30, 2023, we complied with the Filings Requirement. In addition, on August 26, 2024, we effected a 1-for-20 reverse stock split of our common stock following stockholder approval at our annual meeting of stockholders in order to comply with the Minimum Bid Price Requirement. On September 17, 2024, we received a letter from the Nasdaq Staff confirming that we regained compliance and that our securities will continue to be listed on Nasdaq.

On October 4, 2024, we received written notice from Nasdaq that we were not in compliance with Nasdaq Listing Rule 5450(b)(3)(C) (the "Market Value Requirement") as a result of our failure to maintain a minimum market value of publicly held shares of $15,000,000. On December 9, 2024, we received a letter from the Nasdaq Staff confirming that we had regained compliance with the Market Value Requirement and that the matter would be closed.

On July 17, 2025, we received written notice from Nasdaq that we were not in compliance with the Filings Requirement as a result of our failure to timely file the Annual Report on Form 10-K for the fiscal year ended March 31, 2025 (the "2025 10-K"). We regained compliance with the Filings Requirement with respect to the 2025 10-K on August 26, 2025, within the timeline prescribed by Nasdaq.

If we lose compliance again and Nasdaq determines to delist our common stock, our common stock would be traded on the over-the-counter market, and the value and liquidity of our stockholders’ investments would be materially impacted. Furthermore, there can be no assurance that we will maintain compliance with all other Nasdaq listing requirements.

We have identified material weaknesses in our internal control over financial reporting, which could, if not properly remediated, result in additional material misstatements in our interim or annual consolidated financial statements, could impair our ability to produce accurate and timely financial statements and could adversely affect investor confidence in our financial reports, which could negatively affect our business.

We have concluded that our internal control over financial reporting and disclosure controls and procedures were not effective as of March 31, 2026 and 2025 due to the existence of material weaknesses in our internal control over financial reporting, as described in Item 9A. Controls and Procedures of this Annual Report on Form 10-K.

We cannot provide assurance that the material weaknesses and deficiencies described in this Annual Report on Form 10-K will not recur, or that additional material weaknesses in our internal control over financial reporting will not arise or be identified in the future. We intend to continue our control remediation activities and to continue to improve our financial reporting process, and our operational, information technology, financial systems, compliance and infrastructure procedures and controls. We also intend to continue to expand, train, retain and manage our personnel who are essential to effective internal control and compliance. In doing so, we will continue to incur expenses and expend management time and resources.

If our remediation measures are insufficient to address the identified deficiencies, or if additional deficiencies in our internal control over financial reporting are discovered or occur in the future, our consolidated financial statements may contain material misstatements and we could be required to restate our financial results in the future. We have previously restated our financial statements, including in August 2025 with respect to the fiscal quarter ended December 31, 2024 and in May 2024 with respect to the fiscal years ended March 31, 2023 and 2022 and the fiscal quarter ended June 30, 2023. Moreover, because of the inherent limitations of any control system, material misstatements due to error or fraud may not be prevented or detected on a timely basis, or at all. If we are unable to provide reliable and timely financial reports in the future, our business and reputation may be further harmed. Restated financial statements and failures in internal control may also cause us to fail to timely meet reporting obligations, negatively affect investor confidence in our management and the accuracy of our financial statements and disclosures, or result in adverse publicity, any of which could have a negative effect on the price of our common stock, subject us to further regulatory investigations and penalties or stockholder litigation, and materially and adversely impact our business and financial condition.

General Risk Factors

We face risks related to health epidemics, pandemics and other outbreaks, which have had and may in the future have a material adverse effect on our business and results of operations.

We face various risks related to public health issues, including epidemics, pandemics, and other outbreaks. For example, the COVID-19 pandemic and efforts to control its spread had an impact on our workforce and operations, and those of our strategic partners, customers, suppliers, and logistics providers. These impacts included increased component, product, transportation, and overhead costs, increased logistics capacity and flexibility needs, decreased workforce availability, component supply, and product output, increased cybersecurity threats from

Table of Contents

remote work, and general economic downturns. We or our third-party business partners were subject to government restrictions that impacted our ability to continue efficient business operations. Other global health concerns in the future could also result in social, economic and labor instability in the countries in which we or the third parties with whom we engage operate.

Such public health issues have adversely affected and may in the future adversely affect our business and financial results and they may also have the effect of heightening many of the other risks described in more detail in this “Risk Factors” section, such as those relating to adverse global or regional conditions, our highly competitive industry, supply chain disruption, customer demand conditions and our ability to forecast demand, cost saving initiatives, our indebtedness and liquidity, and cyber-attacks.

We are exposed to fluctuations in foreign currency exchange rates, and an adverse change in foreign currency exchange rates relative to our position in such currencies could have a material adverse impact on our business, financial condition and results of operations.

We do not currently use derivative financial instruments for speculative purposes. To the extent that we have assets or liabilities denominated in a foreign currency that are inadequately hedged or not hedged at all, we may be subject to foreign currency losses, which could be significant. Our international operations can act as a natural hedge when both operating expenses and sales are denominated in local currencies. In these instances, although an unfavorable change in the exchange rate of a foreign currency against the U.S. dollar would result in lower sales when translated to U.S. dollars, operating expenses would also be lower in these circumstances. The competitive price of our products relative to others could also be negatively impacted by changes in the rate at which a foreign currency is exchanged for U.S. dollars. Such fluctuations in currency exchange rates could materially and adversely affect our business, financial condition and results of operations.

If the future outcomes related to the estimates used in recording tax liabilities to various taxing authorities result in higher tax liabilities than estimated, then we would have to record tax charges, which could be material.

We have provided amounts and recorded liabilities for probable and estimable tax adjustments required by various taxing authorities in the U.S. and foreign jurisdictions. If events occur that indicate payments of these amounts will be less than estimated, then reversals of these liabilities would create tax benefits recognized in the periods when we determine the liabilities have reduced. Conversely, if events occur which indicate that payments of these amounts will be greater than estimated, then tax charges and additional liabilities would be recorded. In particular, various foreign jurisdictions could challenge the characterization or transfer pricing of certain intercompany transactions. In the event of an unfavorable outcome of such challenge, material tax charges and adverse impacts on operating results could occur in the period in which the matter is resolved or an unfavorable outcome becomes probable and estimable.

Certain changes in stock ownership could result in a limitation on the amount of net operating loss and tax credit carryovers that can be utilized each year. Should we undergo such a change in stock ownership, it would severely limit the usage of these carryover tax attributes against future income, resulting in additional tax charges, which could be material.

We have never paid dividends on our capital stock, and we do not anticipate paying dividends in the foreseeable future.

We have never paid dividends on any of our capital stock and currently intend to retain any future earnings to fund the growth of our business. Any determination to pay dividends in the future will be at the discretion of our Board of Directors, and will depend on our financial condition, operating results, capital requirements, general business conditions and other factors that our Board may deem relevant. As a result, capital appreciation, if any, of our common stock will be the sole source of gain for the foreseeable future.

Anti-takeover provisions contained in our amended and restated certificate of incorporation and amended and restated bylaws, as well as provisions of Delaware law, could impair a takeover attempt.

Our Amended and Restated Certificate of Incorporation, as amended (the “Certificate of Incorporation”), our Amended and Restated Bylaws (the “Bylaws”), and Delaware law, contain provisions that could have the effect of

Table of Contents

rendering more difficult or discouraging an acquisition deemed undesirable by our Board. Our corporate governance documents include provisions:

•authorizing blank check preferred stock, which could be issued with voting, liquidation, dividend, and other rights superior to our common stock;

•limiting the liability of, and providing indemnification to, our directors and officers;

•limiting the ability of our stockholders to call and bring business before special meetings and to take action by written consent in lieu of a meeting;

•requiring advance notice of stockholder proposals for business to be conducted at meetings of our stockholders and for nominations of candidates for election to our Board;

•controlling the procedures for the conduct and scheduling of meetings of the Board and stockholders;

•providing our Board with the express power to postpone and cancel previously scheduled special meetings at any time;

•limiting the determination of the number of directors on our Board and the filling of vacancies or newly created seats on the board to our Board then in office; and

•providing that directors may be removed by stockholders only for cause.

While these provisions have the effect of encouraging persons seeking to acquire control of our Company to negotiate with our Board, they could enable the Board to hinder or frustrate a transaction that some, or a majority, of the stockholders might believe to be in their best interests and, in that case, may prevent or discourage attempts to remove and replace incumbent directors. We are also subject to Delaware laws that could have similar effects. One of these laws prohibits us from engaging in a business combination with a significant stockholder unless specific conditions are met.

ITEM 1C. CYBERSECURITY

Risk Management and Strategy

The Company recognizes the importance of being able to assess, effectively respond to and manage material cybersecurity threats and incidents that may compromise the confidentiality, integrity or availability of its information systems, data or network resources.

As part of its overall enterprise risk management framework, the Company maintains both a Cyber Incident Evaluation Committee (“CIEC”) and an Incident Response Plan (“IRP”). The Company’s CIEC is managed by its Chief Information Officer (the “CIO”) whose team (the Incident Response Team, or “IRT”) is responsible for leading company-wide cybersecurity strategy, policy, standards, architecture, and processes. The purpose of the IRT is to define procedures for reporting and responding to cybersecurity incidents. It creates objectives for actionable procedures that can be measured, evaluated, scaled and revised as necessary for each specific cybersecurity incident. These objectives are designed to maximize the effectiveness of the Company’s response through an established plan of action and assigning responsibilities to appropriate personnel and/or third-party contractors.

If a cybersecurity threat or incident is identified, the IRT will communicate the cybersecurity threat or incident and any damages to the CIEC. The CIEC will assess the materiality of the cybersecurity threat or incident to determine if any public disclosures are required under the SEC’s cybersecurity disclosure rule and make a recommendation to the Board. If deemed necessary, third-party consultants, legal counsel, and assessors will be engaged to evaluate the materiality assessment.

The cybersecurity program of the Company interfaces with other functional areas within the Company, including but not limited to the Company’s brands and information technology, accounting, finance, legal and human resources, as well as external third-party partners, where appropriate, to assess, identify and manage potential cybersecurity threats. The Company regularly assesses and updates its processes, procedures and management techniques in light of ongoing cybersecurity developments.

Recognizing the complexity and evolving nature of cybersecurity threats, the Company also engages with a range of external experts, including cybersecurity assessors and consultants in evaluating and testing its cybersecurity management systems and IRT. These partnerships enable the Company to leverage specialized knowledge and insights, to assist in updating its cybersecurity strategies and processes to align with industry best practices. The Company’s collaboration with these third parties includes consultation and review of security enhancements.

To date, we have not identified risks from cybersecurity threats or incidents, including as a result of any previous cybersecurity incidents, that have materially affected the Company or are reasonably likely to materially affect our operations, business strategy, results of operations, of financial condition. However, the sophistication of and risks from cybersecurity threats and incidents continues to increase, and there can be no assurance that our cybersecurity risk management program and processes, including our IRP, and other preventative actions the Company has taken and continues to take to reduce the risk of cybersecurity threats and incidents and protect its systems and information, will be fully implemented, complied with or successful in protecting against all cybersecurity threats and incidents. For more information on how cybersecurity risk could materially affect the Company’s business strategy, results of operations, or financial condition, please refer to “Item 1A Risk Factors—Risks Related to our Business and Industry—A cybersecurity breach could adversely affect our ability to conduct our business, harm our reputation, expose us to significant liability or otherwise damage our financial results.”

Governance

Our Board considers cybersecurity risk as part of its risk oversight function. The Board oversees management’s implementation of our cybersecurity risk management program. The Board receives periodic reports from the CIEC on our cybersecurity risks and cyber risk management program. In addition, CIEC updates the Board, as necessary, regarding any material cybersecurity incidents, as well as any incidents with lesser impact potential. Board members receive presentations on cybersecurity topics from our CIO, internal security staff or external experts as part of the Board’s continuing education on topics that impact public companies.

Table of Contents

The CIEC is responsible for assessing and managing our material risks from cybersecurity threats. The team has primary responsibility for our overall cybersecurity risk management program and supervises both our internal cybersecurity personnel and our retained external cybersecurity consultants. Our CIEC’s expertise includes a combined 20 plus years of experience in managing security technologies; designing and implementing security strategies; and risk management and incident response across various industries. Our CIEC supervises efforts to prevent, detect, mitigate, and remediate cybersecurity risks and incidents through various means, which may include briefings from internal security personnel; threat intelligence and other information obtained from governmental, public or private sources, including external consultants engaged by us; and alerts and reports produced by security tools deployed in the IT environment.

ITEM 2. PROPERTIES

As of March 31, 2026, our headquarters were located in Centennial, Colorado. We lease facilities in North America, Europe, and Asia Pacific.

Table of Contents

Product Revenue

In fiscal 2026, product revenue increased $18.2 million, or 12%, as compared to fiscal 2025. The primary driver of this increase was strong demand across all secondary storage product lines including Scalar tape storage products, DXi backup appliances, and ActiveScale object storage appliances. Demand growth increased worldwide with product revenues increasing across all regions. Overall secondary storage revenue increased by $27.1 million, or 36.7% as compared to fiscal 2025. Devices and media revenues also increased by $6.1 million, or 17.7% as compared to fiscal 2025. These increases were partially offset by continuing declines in primary storage.

Service and Subscription Revenue

Service and subscription revenue decreased $11.4 million, or 10%, in fiscal 2026 compared to fiscal 2025. This decrease was due in part to certain long-lived products reaching their end-of-service-life, partially offset by new support bookings and the transition towards subscription-based licensing.

Royalty Revenue

We receive royalties from third parties that license our linear-tape open media patents through our membership in the linear-tape open consortium. Royalty revenue decreased $1.2 million, or 14%, in fiscal 2026, as compared to fiscal 2025, related to lower overall unit shipments.

Gross profit	$	103,041	36.9	%	$	109,832	40.1	%	$	(6,791)	(320)

Gross profit and margin percentages are key metrics that management monitors to assess the performance on the business.

Product Gross Margin

Product gross margin decreased 130 basis points for fiscal 2026, as compared to fiscal 2025. This decrease was due primarily to a revenue mix slightly more weighted towards lower margin devices and media products. Product costs also fluctuated through the year from external factors such as import tariffs and component material costs.

Service and Subscription Gross Margin

Service and subscription gross margin decreased 50 basis points for fiscal 2026, as compared to fiscal 2025. This decrease was due primarily to higher shipping and handling costs and inventory carrying charges, partially offset by lowered internal costs from continued improvement in operational design.

Royalty Gross Margin

Royalties do not have significant related cost of sales.

In fiscal 2026, general and administrative expenses decreased $20.0 million, or 31%, as compared with fiscal 2025 This decrease was primarily driven by large non-recurring projects not recurring in fiscal 2026 including the launch of a new ERP system in the prior year. Expenses also decreased as administrative efficiency gains were realized through more streamlined functions and process automation.

In fiscal 2026, research and development expenses decreased $7.6 million, or 25%, as compared with fiscal 2025. This decrease was the result of the efficiencies realized through improved organization design, better aligning commonalities between major products.

In fiscal 2026, restructuring charges increased $4.0 million, or 98%, as compared with fiscal 2025. This increase is driven by corporate restructuring activities as we consolidated our physical footprint and operations in certain markets.

In fiscal 2026, we recorded a non-cash loss of $11.3 million related to the change in fair value of our forbearance warrant which was issued in September 2025. The loss was primarily driven by fluctuations in our stock price. We recorded a non-cash gain of $45.3 million in the same period in fiscal 2025 related to lender warrants issued to the holders of our Term Loan. These warrants were exercised in December 2024 and January 2025. This gain was primarily driven by fluctuations in our stock price.

In fiscal 2026, we recorded a loss of $59.6 million on debt extinguishment primarily related to the September 2025 and December 2025 debt transactions, partially offset by a gain on termination of our revolving credit facility in August 2025. In fiscal 2025, loss on debt extinguishment, net was related to prepayment of our long-term debt.

Income tax provision

Income tax provision	$	1,008	(1)	%	$	821	(1)	%	$	(187)	(23)	%

In fiscal 2026, the income tax provision increased $0.2 million or 23%, compared to fiscal 2025. The income tax provision increased in 2026 primarily due to a higher valuation allowance and a significant warrant mark-to-market adjustment, which together offset the federal statutory tax benefit from pre-tax losses. Additionally, the expiration of tax attributes contributed to the increase, as previously available deferred tax assets could no longer be used.

Due to our history of net losses in the U.S., the protracted period for utilizing tax attributes in certain foreign jurisdictions, and the difficulty in predicting future results, we believe that we cannot rely on projections of future taxable income to realize most of our deferred tax assets. Accordingly, we have established a full valuation allowance against our U.S. and certain foreign net deferred tax assets. Significant management judgment is required in assessing our ability to realize any future benefit from our net deferred tax assets. We intend to maintain this valuation allowance until sufficient positive evidence exists to support its reversal. Our income tax expense recorded in the future will be reduced to the extent that sufficient positive evidence materializes to support a reversal of, or decrease in, our valuation allowance.

Product Revenue

In fiscal 2025, product revenue decreased $20.7 million, or 12%, as compared to fiscal 2024. The primary driver of the decrease was a drop in demand from our large hyperscale customers in the first quarter of the prior year, as well as more general decreases in the overall tape market. Outside of the Tape and Hyperscale business, our remaining Secondary and Primary storage systems are also offered as a subscription.

Service and Subscription Revenue

Service and subscription revenue decreased $15.9 million, or 13%, in fiscal 2025 compared to fiscal 2024. This decrease was due in part to certain long-lived products reaching their end-of-service-life, partially offset by new support bookings and the transition towards subscription-based licensing.

Royalty Revenue

We receive royalties from third parties that license our linear-tape open media patents through our membership in the linear-tape open consortium. Royalty revenue decreased $0.9 million, or 9%, in fiscal 2025, as compared to fiscal 2024, related to lower overall unit shipments.

Gross profit and margin percentages are key metrics that management monitors to assess the performance on the business.

Product Gross Margin

Product gross margin decreased 30 basis points for fiscal 2025, as compared to fiscal 2024. This decrease was due primarily to a revenue mix less weighted towards higher margin tape products.

Service and Subscription Gross Margin

Service and subscription gross margin increased 50 basis points for fiscal 2025, as compared to fiscal 2024. This increase was due primarily to improved operational costs as we implemented strict cost controls and improved our organization design.

Royalty Gross Margin

Royalties do not have significant related cost of sales.

In fiscal 2025, sales and marketing expenses decreased $8.6 million, or 14%, as compared with fiscal 2024. This decrease was primarily driven by an increase in operational cost management, as well as decreased commission expense on lower revenue.

In fiscal 2025, general and administrative expenses increased $12.4 million, or 24%, as compared with fiscal 2024 This increase was primarily driven by large non-recurring costs related to our re-evaluation of revenue recognition, and other non-recurring projects.

In fiscal 2025, research and development expenses decreased $6.9 million, or 18%, as compared with fiscal 2024. This decrease was the result of the continued consolidation of acquisition costs, and efficiencies realized through improved organization design.

In fiscal 2025, restructuring expenses increased $0.8 million, or 25%, as compared with fiscal 2024. This increase is driven by corporate restructuring activities as we consolidated our physical footprint and operations in certain markets.

In fiscal 2025, the income tax provision increased $0.1 million, or 15%, compared to fiscal 2024. The income tax provision increased in 2025 primarily due to a higher valuation allowance and a warrant mark-to-market adjustment, which together offset the federal statutory tax benefit from pre-tax losses. Additionally, the expiration of tax attributes contributed to the increase, as previously available deferred tax assets could no longer be used.

Liquidity and Capital Resources

We consider liquidity in terms of the sufficiency of internal and external cash resources to fund our operating, investing and financing activities. Our principal sources of liquidity include cash from operating activities, cash and cash equivalents on our balance sheet and proceeds from the sale of Common Stock under the SEPA (as defined herein). In fiscal 2025, there were also amounts available under our revolving credit facility agreement with PNC Bank, National Association, as amended from time to time (the “PNC Credit Facility”) however, this agreement was terminated in August 2025. We require significant cash resources to provide for our research and development activities, fund our working capital needs, and make capital expenditures. Our future liquidity requirements will depend on multiple factors, including our research and development plans and capital asset needs.

We had cash and cash equivalents of $15.6 million as of March 31, 2026, which excludes $0.7 million of short-term restricted cash. Our total outstanding Term Loan debt was $55.9 million and the fair value of the Convertible Note (as defined herein) was $90.0 million.

Table of Contents

We generated negative cash flows from operations of approximately $37.9 million and $23.6 million for the fiscal years ended March 31, 2026 and 2025, respectively, and generated net losses of approximately $101.0 million and $115.1 million for the fiscal years ended March 31, 2026 and 2025, respectively. We have funded operations through the sale of common stock under the SEPA and debt borrowings as described in Note 4: Debt.

On January 25, 2025, the Company entered into a Standby Equity Purchase Agreement (the "SEPA") with YA II PN, Ltd., a Cayman Islands exempt limited partnership ("YA"), in which pursuant to and subject to its terms, the Company has the right, but not the obligation, to sell up to $200.0 million of Common Stock at any time during the three-year period following the date of the SEPA. As of March 31, 2026, the Company has sold 8.7 million shares of Common Stock under the SEPA with net proceeds of approximately $91.0 million.

Subsequent to March 31, 2026, we completed several transactions which have significantly impacted our future liquidity. On June 1, 2026, the Company entered into Securities Purchase Agreements to issue and sell to certain accredited investors an aggregate of 10,615,712 shares of the Company’s Common Stock. After deducting placement agent fees and other offering expenses payable by the Company, the Company received net proceeds of $94.7 million. On June 4, 2026, the Company paid an aggregate of $57.8 million in connection with the termination of the Term Loan Credit Agreement. This fully paid down and extinguished our Term Loans (as defined herein). Also on June 4, 2026, the Company provided a notice to YA regarding its termination of the SEPA, effective June 11, 2026. There were no amounts owed to YA under the SEPA at the time the termination notice was provided. See Note 13: Subsequent Events, for further details. With the cash proceeds, after repayment of the Term Loans, we forecast that operating performance, cash and current working capital will provide us with sufficient capital to fund operations for at least one year from the financial statement issuance date.

Net Cash Used in Operating Activities

Net cash used in operating activities increased by $14.2 million to $37.9 million for the year ended March 31, 2026 compared to $23.6 million for the year ended March 31, 2025. The increase was primarily attributable increase in product costs and associated decrease gross profit in addition to large non-recurring costs related to our re-evaluation of Topic 606, and other non-recurring projects.

Net Cash Used in Investing Activities

Net cash used in investing activities was $1.7 million and $4.9 million for the years ended March 31, 2026 and 2025, respectively, primarily attributable to capital expenditures.

Net Cash Provided by Financing Activities

Net cash provided by financing activities was $39.2 million for the year ended March 31, 2026 due primarily to cash proceeds from the SEPA, partially offset by the repayment of the revolver in the first quarter of fiscal 2026.

Table of Contents

Net cash provided by financing activities was $19.3 million for the year ended March 31, 2025 due primarily to cash proceeds from the SEPA, partially offset by the repayment of the PNC Credit Facility in August 2025.

Commitments and Contingencies

Our contingent liabilities consist primarily of certain financial guarantees, both express and implied, related to product liability and potential infringement of intellectual property. We have little history of costs associated with such indemnification requirements and contingent liabilities associated with product liability may be mitigated by our insurance coverage. In the normal course of business to facilitate transactions of our services and products, we indemnify certain parties with respect to certain matters, such as intellectual property infringement or other claims. We also have indemnification agreements with our current and former officers and directors. It is not possible to determine the maximum potential amount under these indemnification agreements due to the limited history of our indemnification claims, and the unique facts and circumstances involved in each particular agreement. Historically, payments made by us under these agreements have not had a material impact on our operating results, financial position or cash flows.

We are also subject to ordinary course of business litigation, See Note 10: Commitments and Contingencies, to our consolidated financial statements included elsewhere in this Annual Report on Form 10-K.

Contractual Obligations

Contractual obligations are cash amounts that we are obligated to pay as part of certain contracts that we have entered into during the normal course of business. Below is a table that shows our contractual obligations as of March 31, 2026 (in thousands):

Off-Balance Sheet Arrangements

We do not currently have any other off-balance sheet arrangements and do not have any holdings in variable interest entities.

CRITICAL ACCOUNTING ESTIMATES AND POLICIES

The preparation of our consolidated financial statements in accordance with generally accepted accounting principles in the United States of America (“GAAP”) requires management to make judgments, estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes included elsewhere in this Annual Report on Form 10-K. On an ongoing basis, we evaluate estimates, which are based on historical experience and on various other assumptions that we believe to be reasonable under the circumstances. We consider the following accounting policies to be critical to understanding our financial statements because the application of these policies requires significant judgment on the part of management, which could have a material impact on our financial statements if actual performance should differ from historical experience or if our assumptions were to change. The following accounting policies include estimates that require management’s subjective or complex judgments about the effects of matters that are inherently uncertain. For information on our

Table of Contents

significant accounting policies, including the policies discussed below, see Note 1: Description of Business and Significant Accounting Policies, to our consolidated financial statements.

Revenue Recognition

Our revenue is derived from three main sources: (a) products, (b) service and subscription, and (c) royalties. Our performance obligations are satisfied at a point in time or over time as stand ready obligations. Product revenue is recognized at the point in time when the customer takes control of the product, which typically occurs at the point of shipment. Service and subscription revenue consists of customer support agreements, software subscriptions, installation, and consulting and training. Our software subscriptions include term licenses which are recognized as revenue when the license has been delivered to the customer and related customer support, which is recognized ratably over the service period. Revenue from customer support agreements is recognized ratably over the contractual term of the agreement. Installation services are typically completed within a short period of time and revenue from these services is recognized at the point when installation is complete. A majority of our consulting and training revenue does not take significant time to complete therefore these obligations are satisfied upon completion of such services over time as each day is completed. We license certain products under royalty arrangements, pursuant to which our licensees periodically provide us with reports containing units sold to end users subject to the royalties. The reports substantiate that our performance obligation has been satisfied and we recognize royalty revenue based on the reports or when amounts can be reasonably estimated.

There are significant judgments used when applying Accounting Standards Codification (“ASC”) Topic 606, Revenue from Contracts with Customers ("Topic 606"), to contracts with customers. Most of our contracts contain multiple goods and services designed to meet each customer's unique storage needs. For contracts with multiple performance obligations, we allocate the transaction price to each performance obligation based on the relative standalone selling price of the good or service underlying each performance obligation. Where standalone selling price may not be directly observable (e.g., the performance obligation is not sold separately), we maximize the use of observable inputs by using information including internal discounting practices, competitor pricing, competitor margins, performance obligations with similar customers and product groupings. Determining the observable inputs and applying them to our performance obligations requires significant judgment. We reassess standalone selling price determination periodically.

Product revenue may be impacted by a variety of price adjustments or other factors, including rebates, returns and stock rotation. We use the expected value method to estimate the net consideration expected to be returned by the customer. We use historical data and current trends to drive our estimates. We record a reduction to revenue to account for these items that may result in variable consideration. We initially measure a returned asset at the carrying amount of the inventory, less any expected costs to recover the goods including potential decreases in value of the returned goods.

Income Taxes

Deferred tax assets and liabilities are recognized based on temporary differences between the financial reporting and tax bases of assets and liabilities, measured at the enacted tax rates expected to apply to taxable income in the years in which those tax assets or liabilities are expected to be realized or settled. Based on the evaluation of available evidence, both positive and negative, we recognize future tax benefits, such as net operating loss carryforwards and tax credit carryforwards, to the extent that realizing these benefits is considered to be more likely than not.

A valuation allowance is provided if we believe it is more likely than not that all or some portion of the deferred tax asset will not be realized. An increase or decrease in the valuation allowance, if any, that results from a change in circumstances, and which causes a change in our judgment about the realizability of the related deferred tax asset, is included in the tax provision.

We recognize the financial statement effects of an uncertain income tax position when it is more likely than not, based on technical merits, that the position will be sustained upon examination. We reevaluate these uncertain tax positions on a quarterly basis. This evaluation is based on factors including, but not limited to, changes in facts or circumstances and changes in tax law. We recognize penalties and tax-related interest expense as a component of income tax expense in our consolidated statements of operations and comprehensive loss. See Note 9: Income Taxes, to our consolidated financial statements included elsewhere in this Annual Report on Form 10-K.

Inventories

Table of Contents

Manufacturing Inventories

Our manufacturing inventories are recorded at the lower of cost or net realizable value, with cost being determined on a first-in, first-out (“FIFO”) basis. Costs include material, direct labor, and an allocation of overhead. Adjustments to reduce the cost of manufacturing inventory to its net realizable value, if required, are made for estimated excess, obsolete or impaired balances. Factors influencing these adjustments include declines in demand, rapid technological changes, product life cycle and development plans, component cost trends, product pricing, physical deterioration and quality issues. Revisions to these adjustments would be required if these factors differ from our estimates.

Service Parts Inventories

Our service parts inventories are recorded at the lower of cost or net realizable value, with cost being determined on a FIFO basis. Service parts inventories consist of both component parts, which are primarily used to repair defective units, and finished units, which are provided for customer use permanently or on a temporary basis while the defective unit is being repaired. We record adjustments to reduce the carrying value of service parts inventory to its net realizable value and dispose of parts with no use and a net realizable value of zero. Factors influencing these adjustments include product life cycles, end of service life plans and the volume of enhanced or extended warranty service contracts. Estimates of net realizable value involve significant estimates and judgments about the future, and revisions would be required if these factors differ from our estimates.

Warrant Accounting

We account for warrants as either equity-classified or liability-classified instruments based on an assessment of the warrant’s specific terms and applicable authoritative guidance: ASC 480, Distinguishing Liabilities from Equity (“Topic 480”) and ASC 815, Derivatives and Hedging (“Topic 815”). The assessment considers whether the warrants are freestanding financial instruments pursuant to Topic 480, meet the definition of a liability pursuant to Topic 480, and whether the warrants meet all of the requirements for equity classification under Topic 815, including whether the warrants are indexed to the Company’s own shares of common stock and whether the warrant holders could potentially require “net cash settlement” in a circumstance outside of the Company’s control, among other conditions for equity classification. This assessment, which requires the use of professional judgment, is conducted at the time of warrant issuance and as of each subsequent quarterly period end date while the warrants are outstanding.

For issued or modified warrants that meet all of the criteria for equity classification, the warrants are required to be recorded as a component of additional paid-in capital at the time of issuance or modification. For issued or modified warrants that do not meet all the criteria for equity classification, the warrants are required to be recorded at their initial fair value on the date of issuance, and each balance sheet date thereafter. This liability is subject to re-measurement at each balance sheet date until exercised, and any change in fair value is recognized in the Company’s consolidated statement of operations.

Convertible Note

Pursuant to ASC Topic 825, Financial Instruments (“ASC 825”), the Company has elected the fair value option for the convertible note issued in December 2025 (the “Convertible Note”). The Convertible Note is initially recorded at its estimated fair value on the date of issuance and subsequently remeasured at fair value at each reporting period-end. Changes in fair value are recognized in earnings in “Change in fair value of Convertible Note” in the condensed consolidated statements of operations and comprehensive loss, which includes the component related to accrued interest. In accordance with ASC 825, the portion of the change in fair value attributable to instrument-specific credit risk is recognized in other comprehensive income. For the year ended March 31, 2026, the Company determined that the change attributable to instrument-specific credit risk was immaterial. See Note 11: Fair Value of Financial Instruments, with respect to the fair value option election, and Note 4: Debt, for a discussion of the Convertible Note.

Recently Issued and Adopted Accounting Pronouncements

For recently issued and adopted accounting pronouncements, see Note 1: Description of Business and Significant Accounting Policies, to our consolidated financial statements.

Table of Contents

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Market risk represents the risk of loss that may impact our financial position due to adverse changes in financial market prices and rates. Our market risk exposure is primarily a result of exposure due to potential changes in inflation or interest rates. We do not hold financial instruments for trading purposes.

Interest Rate Risk

We are subject to interest rate risk on borrowings under our variable interest rate term debt. See Note 4: Debt to our consolidated financial statements for a description of our long-term debt. Changes in the market interest rate will increase or decrease our interest expense. Assuming no change in the outstanding borrowings under the term debt during fiscal 2026, a hypothetical 100-basis point increase or decrease in market interest rates sustained throughout the year would not result in a material change to our annual interest expense. Our other long-term debt related to lease obligations have fixed interest rates and terms, and as such, we consider the associated risk to our results of operations from changes in market rates of interest applied to our lease obligations to be minimal.

Foreign Exchange Risk

We conduct business in certain international markets. Because we operate in international markets, we have exposure to different economic climates, political arenas, tax systems and regulations that could affect foreign exchange rates. Our primary exposure to foreign currency risk relates to transacting in foreign currency and recording the activity in U.S. dollars. Changes in exchange rates between the U.S. dollar and these other currencies will result in transaction gains or losses, which we recognize in our consolidated statements of operations and comprehensive loss.

To the extent practicable, we minimize our foreign currency exposures by maintaining natural hedges between our assets and liabilities and revenues and expenses denominated in foreign currencies. We may enter into foreign exchange derivative contracts or other economic hedges in the future. Our goal in managing our foreign exchange risk is to reduce to the extent practicable our potential exposure to the changes that exchange rates might have on our earnings.

Quantum Corporation

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheet of Quantum Corporation and subsidiaries (the “Company”) as of March 31, 2026, and the related consolidated statements of operations and comprehensive loss, changes in stockholders’ deficit, and cash flows for the year then ended, and the related notes (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of March 31, 2026, and the results of their operations and their cash flows for the year then ended in conformity with accounting principles generally accepted in the United States of America.

The consolidated financial statements of the Company as of March 31, 2025, were audited by other auditors whose report dated August 26, 2025, expressed an unqualified opinion on those statements.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (“PCAOB”), the Company’s internal control over financial reporting as of March 31, 2026, based on criteria established in 2013 Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) and our report dated June 25, 2026, expressed an adverse opinion.

Basis for Opinion

These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s consolidated financial statements based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. Our audit included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audit also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audit provides a reasonable basis for our opinion.

Critical Audit Matters

The critical audit matters communicated below are matters arising from the current period audit of the consolidated financial statements that were communicated or required to be communicated to the audit committee and that: (1) relate to accounts or disclosures that are material to the consolidated financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate.

Determination of Standalone Selling Price

As described further in Note 1 to the consolidated financial statements, the Company’s contracts with customers often include multiple performance obligations. The transaction price of each contract is allocated to individual performance obligations based upon relative stand-alone selling price (“SSP”). The SSP of performance obligations is determined based on observable prices at which the Company separately sells the products and services or alternative methods. If the SSP is not directly observable, the Company will estimate the SSP considering historical and current selling prices, internal discounting practices, and competitor information for similar products/services, which can require significant judgment and are subject to change based on continuous reevaluation.

Table of Contents

Significant judgment is exercised by the Company in determination and allocation of stand-alone selling prices for each distinct performance obligation, for products and services that are not sold separately.

Given these factors, the related audit effort in evaluating management’s judgments in determining and allocating the SSP of performance obligations was challenging, subjective, and complex and required a high degree of auditor judgment.

How our audit addressed the Critical Audit Matter

Our principal audit procedures related to the determination and allocation of the SSP of performance obligations included the following:

•We gained an understanding of and evaluated the design and implementation of the Company’s controls that address the risk of material misstatement related to the determination and allocation of SSP to performance obligations.

•We evaluated management’s significant accounting policies related to revenue recognition for reasonableness.

•We evaluated the appropriateness of the overall methodology used by management to develop the estimates, including considering whether the methodology maximized the use of observable outputs.

•We evaluated the reasonableness of management’s estimate of stand-alone selling prices for products and services that are not sold separately.

•We tested management’s process, including by evaluating key assumptions for performance obligations that do not include directly observable sales. Specifically, included in our procedures we:

◦considered the consistency with external market and competitor margin data for products and services;

◦evaluated the appropriateness of the categorization and classification of products and services;

◦recalculated and evaluated the inputs used in management’s calculations, including selling prices and discounts;

◦evaluated the completeness and accuracy of management’s calculations of estimated selling prices, including the allocation between products and services.

Quantum Corporation

Adverse Opinion on Internal Control over Financial Reporting

We have audited Quantum Corporation and subsidiaries (the "Company") internal control over financial reporting as of March 31, 2026, based on criteria established in Internal Control—Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission ("COSO"). In our opinion, because of the effect of the material weaknesses described below on the achievement of the objectives of the control criteria, the Company has not maintained effective internal control over financial reporting as of March 31, 2026, based on criteria established in Internal Control—Integrated Framework (2013) issued by COSO.

A material weakness is a control deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of the Company’s annual or interim consolidated financial statements will not be prevented or detected on a timely basis. The following material weaknesses have been identified and included in management’s assessment:

Revenue Recognition — The Company did not maintain effective internal control related to revenue recognition for the following: (i) internal control for reviewing and updating deferred revenue schedules; (ii) internal control over the accuracy of the inputs into the sales order entry process; and (iii) internal control over the allocation of revenue to performance obligations on a stand-alone selling price basis.

Inventories — The Company did not maintain effective internal control related to inventories. Specifically, internal control over the reconciliation of physical inventories with the Company’s underlying system records.

Income taxes – The Company did not maintain effective internal control related to income taxes. Specifically, the Company did not document and review relevant facts and apply the appropriate tax accounting under accounting standards generally accepted in the United States of America.

Control Environment — The Company did not maintain effective entity-level internal control within the control environment to prevent or detect material misstatements to the consolidated financial statements. Specifically, the Company (i) did not maintain a sufficient complement of trained, knowledgeable resources to execute their responsibilities with respect to internal control over financial reporting for certain financial statements accounts and disclosures; and (ii) conducted inadequate monitoring activities resulting in untimely or ineffective identification of internal control risks to support the design implementation and evaluation of the internal control necessary to provide effective oversight over financial reporting.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) ("PCAOB"), the consolidated balance sheet and the related consolidated statements of operations and comprehensive loss, stockholders’ deficit, and cash flows of the Company as of and for the year ended March 31, 2026, and our report dated June 25, 2026 expressed an unqualified opinion.

Basis for Opinion

The Company’s management is responsible for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Annual Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting

Table of Contents

was maintained in all material respects. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Opinion on the financial statements

We have audited the accompanying consolidated balance sheet of Quantum Corporation (a Delaware corporation) and subsidiaries (the “Company”) as of March 31, 2025, the related consolidated statements of operations and comprehensive loss, changes in stockholders’ deficit, and cash flows for the year in the period ended March 31, 2025, and the related notes (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of March 31, 2025, and the results of its operations and its cash flows for the year in the period ended March 31, 2025, in conformity with accounting principles generally accepted in the United States of America.

Basis for opinion

These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s consolidated financial statements based on our audit. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (“PCAOB”) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audit, we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audit included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audit also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audit provides a reasonable basis for our opinion.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1: DESCRIPTION OF BUSINESS AND SIGNIFICANT ACCOUNTING POLICIES

Description of Business

Quantum Corporation, together with its consolidated subsidiaries (“Quantum”, the “Company”, "our" or "we"), stores and manages digital video and other forms of unstructured data, providing streaming performance for video and rich media applications, along with low-cost, long-term storage systems for data protection and archiving. The Company helps customers around the world capture, create and share digital data and preserve and protect it for decades. The Company’s software-defined, hyperconverged storage solutions span from non-violate memory express (“NVMe”), to solid state drives (“SSD”), hard disk drives, (“HDD”), tape and the cloud and are tied together leveraging a single namespace view of the entire data environment. The Company works closely with a broad network of distributors, value-added resellers (“VARs”), direct marketing resellers (“DMRs”), original equipment manufacturers (“OEMs”) and other suppliers to meet customers’ evolving needs.

Basis of Presentation

The consolidated financial statements and accompanying notes have been prepared in accordance with generally accepted accounting principles in the United States of America (“GAAP”). All intercompany balances and transactions have been eliminated. The Company reviews subsidiaries and affiliates, as well as other entities, to determine if they should be considered variable interest entities (“VIE”), and whether it should change the consolidation determinations based on changes in their characteristics. The Company considers an entity a VIE if its equity investors own an interest therein that lacks the characteristics of a controlling financial interest, or if such investors do not have sufficient equity at risk for the entity to finance its activities without additional subordinated financial support, or if the entity is structured with non-substantive voting interests. To determine whether or not the entity is consolidated with the Company’s results, the Company also evaluates which interests are variable interests in the VIE and which party is the primary beneficiary of the VIE. There were no VIEs for the years ended March 31, 2026 or 2025.

Reclassifications

Certain prior-period amounts in the condensed consolidated statements of cash flows have been reclassified to conform to the current period presentation. These reclassifications had no effect on total cash flows. Also, due to the size of the Balance, we have aggregated Manufacturing and Service Inventory into a single line called Inventories on the Consolidated Balance Sheets. Details of the balances in the Inventories line item has been included in Note 3: Balance Sheet Information.

Reverse Stock Split

On August 15, 2024, the Company's stockholders approved an amendment to the Company's Amended and Restated Certificate of Incorporation to effect a reverse stock split of the issued shares of the Company’s common stock, par value $0.01 per share, at a ratio ranging from 1-for-5 shares up to a ratio of 1-for-20 shares, with the exact ratio, if any, to be selected by the Board and set forth in a public announcement. On August 15, 2024, the Board approved a 1-for-20 reverse stock split (the “Reverse Stock Split”) of the common stock. The Reverse Stock Split became effective as of August 26, 2024 at 4:01 p.m., Eastern Time (the “Effective Time”). At the Effective Time, every twenty issued shares of common stock were automatically reclassified into one issued share of common stock, with any fractional shares resulting from the Reverse Stock Split rounded up to the nearest whole share. The number of outstanding shares of common stock was reduced from approximately 95.9 million shares to approximately 4.8 million shares.

All share and per share amounts for common stock in these consolidated financial statements and notes thereto have been retroactively adjusted for all periods presented to give effect to the Reverse Stock Split.

Liquidity

These consolidated financial statements have been prepared in accordance with GAAP assuming the Company will continue as a going concern. The going concern assumption contemplates the realization of assets and satisfaction of liabilities in the normal course of business.

Table of Contents

The Company generated negative cash flows from operations of approximately $37.9 million and $23.6 million for the fiscal years ended March 31, 2026 and 2025, respectively, and generated net losses of approximately $101.0 million and $115.1 million for the fiscal years ended March 31, 2026 and 2025, respectively. The Company has funded operations through the sale of common stock and term debt borrowings in Note 4: Debt and Note 7: Common Stock. Management believes that it has the ability to obtain additional debt or equity financing, if required, and has historically been able to do so. Management also believes that current working capital will provide the Company with sufficient capital to fund operations for at least one year from the consolidated financial statement issuance date.

As previously disclosed, the Company identified that there was substantial doubt about the Company’s ability to continue as a going concern. This was due to the requirement to repay the Term Loans (as defined herein) on August 5, 2026. Subsequent to March 31, 2026, the Company completed several transactions which resulted in the repayment of the Term Loans and removed the substantial doubt noted above. On June 1, 2026, the Company entered into Securities Purchase Agreements to issue and sell to certain accredited investors an aggregate of 10,615,712 shares of the Company’s common stock. After deducting placement agent fees and other offering expenses payable by the Company, the Company received net proceeds of $94.7 million. On June 4, 2026, the Company paid an aggregate of $57.8 million in connection with the termination of the Term Loan Credit Agreement. This fully paid down and extinguished the Company's Term Loans. Also on June 4, 2026, the Company provided a notice to YA II PN, Ltd. ("YA") regarding its termination of the Standby Equity Purchase Agreement (the "SEPA"), effective June 11, 2026. There were no amounts owed to YA under the SEPA at the time the termination notice was provided. See Note 13: Subsequent Events, for further details. With the cash proceeds, after repayment of the Term Loans, the Company forecasts that operating performance, cash and current working capital will provide sufficient capital to fund operations for at least one year from the financial statement issuance date.

Use of Estimates

The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported and disclosed in the consolidated financial statements and accompanying notes. Actual results could differ from these estimates and assumptions due to risks and uncertainties. Such estimates include, but are not limited to, the determination of standalone selling price for revenue arrangements with multiple performance obligations, inventory adjustments, useful lives of intangible assets and property and equipment, stock-based compensation, fair value of warrants, fair value of the convertible note and provision for income taxes including related reserves. Management bases its estimates on historical experience and on various other assumptions which management believes to be reasonable, the results of which form the basis for making judgments about the carrying values of assets and liabilities.

Cash and Cash Equivalents

The Company has cash deposits and cash equivalents deposited in or managed by major financial institutions. Cash equivalents include all highly liquid investment instruments with an original maturity of three months or less and consist primarily of money market accounts. At times the related amounts are in excess of amounts insured by the Federal Deposit Insurance Corporation. The Company has not experienced any losses with these financial institutions and does not believe such balances are exposed to significant credit risk.

Restricted Cash

Restricted cash is comprised of bank guarantees and similar required minimum balances that serve as cash collateral in connection with various items including insurance requirements, value added taxes, ongoing tax audits and leases in certain countries.

Accounts Receivable and Allowance for Credit Losses

Accounts receivable are recorded at the invoiced amount, and stated at realizable value, net of an allowance for credit losses. The Company maintains an allowance for credit losses for estimated losses based on historical experience and expected collectability of outstanding accounts receivable. The Company performs ongoing credit evaluations of its customers’ financial condition, and for the majority of its customers require no collateral. For customers that do not meet the Company’s credit standards, the Company may require a form of collateral, such as cash deposits or letters of credit, prior to the completion of a transaction. These credit evaluations require significant judgment and are based on multiple sources of information. The Company analyzes such factors as its historical bad debt experience, industry and geographic concentrations of credit risk, current economic trends and changes in

Table of Contents

customer payment terms. The Company will write-off customer balances in full to the reserve when it has determined that the balance is not recoverable. Changes in the allowance for credit losses are recorded in general and administrative expenses.

Fair Value of Financial Instruments

The carrying value of our financial instruments approximates fair value.

Inventories

Manufacturing inventories are recorded at the lower of cost or net realizable value, with cost being determined on a first-in, first-out (“FIFO”) basis. Costs include material, direct labor, and an allocation of overhead in the case of work in process. Adjustments to reduce the cost of manufacturing inventory to its net realizable value, if required, are made for estimated excess, obsolete or impaired balances. Factors influencing these adjustments include declines in demand, rapid technological changes, product life cycle and development plans, component cost trends, product pricing, physical deterioration and quality issues. Revisions to these adjustments would be required if these factors differ from the Company’s estimates.

Service parts inventories are recorded at the lower of cost or net realizable value, with cost being determined on a FIFO basis. The Company carries service parts because it generally provides product warranty for one to three years and earns revenue by providing enhanced and extended warranty and repair services during and beyond this warranty period. Service parts inventories consist of both component parts, which are primarily used to repair defective units, and finished units, which are provided for customer use permanently or on a temporary basis while the defective unit is being repaired. The Company records adjustments to reduce the carrying value of service parts inventory to its net realizable value and disposes of parts with no use and a net realizable value of zero. Factors influencing these adjustments include product life cycles, end of service life plans and volume of enhanced or extended warranty service contracts. Estimates of net realizable value involve significant estimates and judgments about the future, and revisions would be required if these factors differ from the Company’s estimates.

Property and Equipment

Property and equipment are carried at cost, less accumulated depreciation and amortization, computed on a straight-line basis over the estimated useful lives of the assets as follows:


Machinery and equipment			3 to 5 years



Furniture and fixtures			5 years

Leasehold improvements			Shorter of useful life or life of lease

When assets are retired or otherwise disposed of, the related costs and accumulated depreciation are removed from the balance sheet and any resulting gain or loss is reflected in the consolidated statements of operations and comprehensive loss in the period realized.

The Company evaluates the recoverability of the carrying amount of its property and equipment whenever events or changes in circumstances indicate that the carrying amount of an asset group may not be fully recoverable. A potential impairment charge is evaluated when the undiscounted expected cash flows derived from an asset group are less than its carrying amount. Impairment losses, if applicable, are measured as the amount by which the carrying value of an asset group exceeds its fair value and are recognized in operating results. Judgment is used when applying these impairment rules to determine the timing of impairment testing, the undiscounted cash flows used to assess impairments and the fair value of the asset group.

Goodwill

Goodwill represents the excess of the purchase price consideration over the estimated fair value of the tangible and intangible assets acquired and liabilities assumed in a business combination. Goodwill is evaluated for impairment annually in the third quarter of the Company's fiscal year as a single reporting unit, and whenever events or changes in circumstances indicate the carrying value of goodwill may not be recoverable. The Company may elect to qualitatively assess whether it is more likely than not that the fair value of its reporting unit is less than its carrying value. If the Company opts not to qualitatively assess, a quantitative goodwill impairment test is performed. The quantitative test compares its reporting unit's carrying amount, including goodwill, to its fair value calculated based on its enterprise value. If the carrying amount exceeds its fair value, an impairment loss is recognized for the

Table of Contents

excess. The Company did not recognize any impairment of goodwill in any of the periods presented in the consolidated financial statements.

Purchased Intangible Assets

Purchased intangible assets with finite lives are stated at cost, net of accumulated amortization. The Company amortizes its intangible assets on a straight-line basis over an estimated useful life of two to four years.

Impairment of Long-Lived Assets

The Company reviews its long-lived asset group, including property and equipment and finite-lived intangible assets, for impairment annually, or whenever events or changes in circumstances indicate the carrying amount of an asset may not be recoverable. The Company measures the recoverability of this asset group by comparing the carrying amounts to the future undiscounted cash flows the asset group is expected to generate. If the total of the future undiscounted cash flows is less than the carrying amount of an asset group, the Company records an impairment charge for the amount by which the carrying amount of the asset group exceeds its fair market value.

Operating Leases

The Company determines if an arrangement contains a lease at inception. Lease liabilities are recognized at the present value of the future lease payments at commencement date. The interest rates implicit in the Company's operating leases are not readily determinable, and therefore, an incremental borrowing rate is estimated to determine the present value of future payments. The estimated incremental borrowing rate factors in a hypothetical interest rate on a collateralized basis with similar terms, payments, and economic environments. The operating lease right-of-use ("ROU") asset is determined based on the lease liability initially established and reduced for any prepaid lease payments and any lease incentives. The Company accounts for the lease and non-lease components of operating lease contract consideration as a single lease component.

Certain of the operating lease agreements contain rent concession, rent escalation, and option to renew provisions. Rent concession and rent escalation provisions are considered in determining the lease cost. Lease cost is recognized on a straight-line basis over the lease term commencing on the date the Company has the right to use the leased property. The Company generally uses the base, non-cancelable, lease term when recognizing the lease assets and liabilities, unless it is reasonably certain that an extension or termination option will be exercised.

Certain operating leases require the Company to pay taxes, insurance, maintenance, and other operating expenses associated with the leased asset. Such amounts are not included in the measurement of the lease liability to the extent they are variable in nature. These variable lease costs are recognized as a variable lease expense when incurred.

In addition, certain operating lease agreements contain tenant improvement allowances from the Company's landlords. These allowances are accounted for as lease incentives and reduce its ROU asset and lease cost over the lease term.

The Company has applied the practical expedient for short-term leases which have a lease term of less than 12 months and do not include an option to purchase the underlying asset that is reasonably certain to be exercised. The Company recognizes rent expense in the consolidated statements of operations and comprehensive loss on a straight-line basis over the lease term and record variable lease payments as incurred.

Revenue Recognition

The Company generates revenue from three main sources: (1) product, (2) service and subscription, and (3) royalties. Sales tax collected on sales is netted against government remittances and thus, recorded on a net basis. The Company's performance obligations are satisfied at a point in time or over time as stand ready obligations. The majority of revenue is recognized at a point in time when products are accepted or based upon shipping terms when control transfers.

Product Revenue

The Company's product revenue is comprised of multiple storage solution hardware and software offerings targeted towards consumer and enterprise customers. Revenue from product sales is recognized at the point in time when the customer takes control of the product. If there are significant post-delivery obligations, the related revenue is

Table of Contents

deferred until such obligations are fulfilled. Revenue from contracts with customer acceptance criteria are recognized upon end user acceptance.

Service and Subscription Revenue

Service and subscription revenue consists of four components: (a) post-contract customer support agreements,

(b) software subscriptions, (c) installation, and (d) consulting and training.

Customers have the option to choose between different levels of hardware and software support. The Company's support plans include various stand-ready obligations such as technical assistance hot-lines, replacement parts maintenance, and remote monitoring that are delivered whenever called upon by its customers. Support plans provide additional services and assurance outside the scope of the Company's primary product warranties. Revenue from support plans is recognized ratably over the contractual term of the service contract as this aligns with delivery to the customer.

The Company also sells software subscriptions that include term licenses, which are recognized as revenue when the license is delivered to the customer, and related customer support, which is recognized ratably over the service period.

The Company offers installation services on all its products. Customers can opt to either have Quantum or a Quantum-approved third-party service provider install its products. Installation services are typically completed within a short period of time and revenue from these services are recognized at the point when installation is complete.

A majority of the Company's consulting and training revenue does not take significant time to complete therefore these obligations are satisfied over time as each day is completed.

Royalty Revenue

The Company licenses certain intellectual property to third-party manufacturers which gives the manufacturers rights to intellectual property including the right to either manufacture or include the intellectual property in their products for resale. Licensees pay the Company a per-unit royalty for sales of their products that incorporate its intellectual property. On a periodic and timely basis, the licensees provide the Company with reports containing units sold to end users subject to the royalties. The reports substantiate that the performance obligation has been satisfied therefore revenue is recognized based on the reports or when amounts can be reasonably estimated.

Deferred Revenue

Deferred revenue primarily consists of amounts that have been invoiced, which are typically with net 45-day payment terms, but have not yet been recognized as revenue and performance obligations pertaining to service and subscription contracts which have not been satisfied as of the year end. The current portion of deferred revenue represents the amounts that are expected to be recognized as revenue within one year of the consolidated balance sheet dates.

Significant Judgments

The Company generally enters into contracts with customers to provide storage solutions to meet their individual needs. Most of the Company’s contracts contain multiple goods and services designed to meet each customer's unique storage needs. Contracts with multiple goods and services have multiple distinct performance obligations as the promise to transfer hardware, installation services, and support services are capable of being distinct and provide economic benefit to customers on their own.

Standalone selling price

For contracts with multiple performance obligations, the Company allocates the transaction price to each performance obligation based on the relative standalone selling price (“SSP”) of the good or service underlying each performance obligation. The SSP represents the amount for which the Company would sell the good or service to a customer on a standalone basis (i.e., not sold as a bundle with any other products or services). Where SSP may not be directly observable (e.g., the performance obligation is not sold separately), the Company maximized the use of observable inputs by using information including historical and current selling prices, internal discounting practices, competitor information for similar customers and similar products/services, and other observable inputs.

Table of Contents

Variable consideration

Product revenue includes multiple types of variable consideration, such as rebates, returns, or stock rotations. All contracts with variable consideration require payment upon satisfaction of the performance obligation typically with net 45-day payment terms. The Company does not include significant financing components in its contracts. The Company constrains estimates of variable consideration to amounts that are not expected to result in a significant revenue reversal in the future, primarily based on the expected value of consideration to be returned to the customer under the specific terms of the underlying programs.

The expected value method is used to estimate the consideration expected to be returned to the customer. The Company uses historical data and current trends to drive the estimates. The Company records a reduction to revenue to account for these programs. For inventory returns, the Company initially measures this asset at the carrying amount of the inventory, less any expected costs to recover the goods including potential decreases in the value of the returned goods.

Costs of Obtaining Contracts with Customers

The Company’s primary cost to obtain contracts is sales commissions earned by sales representatives. These costs are incremental and expected to be recovered indirectly through the margin inherent within the contract. A large portion of the Company’s contracts are completed within a one-year performance period, and for contracts with a specified term of one year or less, the Company has elected to apply a practical expedient available in Topic 340-40: Other Assets and Deferred Costs – Contracts with Customers, which allows the Company to recognize the incremental costs of obtaining a contract as an expense when incurred if the amortization period of the asset that the Company would otherwise have recognized is one year or less.

Sales commissions earned on contracts exceeding one year qualify for capitalization after application of the practical expedient. The duration of these contracts ranges from 1-7 years. Total capitalized costs were $2.3 million and $2.3 million for fiscal 2026 and 2025, respectively. Total amortization of capitalized costs of obtaining revenue contracts were $1.3 million and $1.3 million for fiscal 2026 and 2025, respectively. These costs are recognized on a straight-line basis over the associated sales contract term.

Cost of Service and Subscription Revenue

The Company classifies expenses as service cost of revenue by estimating the portion of its total cost of revenue that relates to providing field support to its customers under contract. These estimates are based upon a variety of factors, including the nature of the support activity and the level of infrastructure required to support the activities from which it earns service and subscription revenue. In the event its service business changes, its estimates of cost of service and subscription revenue may be impacted.

Research and Development Costs

Expenditures relating to the development of new products and processes are expensed as incurred. These costs include expenditures for employee compensation, materials used in the development effort, other internal costs, as well as expenditures for third-party professional services. The Company has determined that technological feasibility for its software products is reached shortly before the products are released to manufacturing. Costs incurred after technological feasibility is established have not been material, therefore, the Company expenses software-related research and development costs as incurred.

Internal-use Software Costs

The Company capitalizes costs incurred to implement software solely for its internal use, including (i) hosted applications used to deliver the Company's support services, and (ii) certain implementation costs incurred in a hosting arrangement that is a service contract when the preliminary project stage is complete, management with the relevant authority authorizes and commits to the funding of the software project, and it is probable the project will be completed and used to perform the intended function.

Software implementation costs are capitalized to either other current assets or other long-term assets on the Company's consolidated balance sheets and amortized over 10 years starting when the software is ready for its intended use. Software implementation costs capitalized were $0.0 million and $1.0 million in fiscal 2026 and 2025, respectively. Related amortization expense for software implementation costs was $1.9 million and $1.8 million during fiscal 2026 and 2025, respectively.

Table of Contents

Advertising Expense

Advertising expense is recorded as incurred and was $1.9 million and $2.0 million in fiscal 2026 and 2025, respectively.

Shipping and Handling Fees

Shipping and handling fees are included in cost of revenue as incurred and were $11.9 million and $6.8 million in fiscal 2026 and 2025, respectively.

Accrued Restructuring Charges

Accrued restructuring charges include charges related to the realignment and restructuring of the Company’s business operations. These charges represent judgments and estimates of the Company’s costs of severance, closure and consolidation of facilities and settlement of contractual obligations under its operating leases, including sublease rental rates, asset write-offs and other related costs. The Company reassesses the restructuring liability requirements to complete each individual plan under the restructuring programs at the end of each reporting period. If these estimates change in the future or actual results differ from the Company’s estimates, additional charges may be required. See Note 6: Restructuring Charges, for more information.

Foreign Currency Translation

The Company's international operations generally use their local currency as their functional currency. Assets and liabilities are translated at exchange rates in effect at the balance sheet date. Income and expense accounts are translated at the average monthly exchange rates during the year. Resulting translation adjustments are reported as a component of other comprehensive loss and recorded in accumulated other comprehensive loss in the accompanying consolidated balance sheets.

Warrant Accounting

The Company accounts for warrants as either equity-classified or liability-classified instruments based on an assessment of the warrant’s specific terms and applicable authoritative guidance ASC Topic 480, Distinguishing Liabilities from Equity (“Topic 480”) and ASC Topic 815, Derivatives and Hedging (“Topic 815”). The assessment considers whether the warrants are freestanding financial instruments pursuant to Topic 480, meet the definition of a liability pursuant to Topic 480, and whether the warrants meet all of the requirements for equity classification under Topic 815, including whether the warrants are indexed to the Company’s own common shares and whether the warrant holders could potentially require “net cash settlement” in a circumstance outside of the Company’s control, among other conditions for equity classification. This assessment, which requires the use of professional judgment, is conducted at the time of warrant issuance and as of each subsequent quarterly period end date while the warrants are outstanding.

Income Taxes

The Company accounts for income taxes in accordance with ASC Topic 740, Income Taxes, in which deferred tax assets and liabilities are recognized based on differences between the financial reporting carrying values of assets and liabilities and the tax basis of those assets and liabilities, measured at the enacted tax rates expected to apply to taxable income in the years in which those tax assets or liabilities are expected to be realized or settled.

A valuation allowance is provided if the Company believes it is more likely than not that all or some portion of the deferred tax asset will not be realized. An increase or decrease in the valuation allowance, if any, that results from a change in circumstances, and which causes a change in the Company’s judgment about the realizability of the related deferred tax asset, is included in the tax provision.

Table of Contents

The Company assesses whether tax benefits claimed or expected to be claimed on a tax return should be recorded in the consolidated financial statements. The Company may recognize the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, including resolution of any related appeals or litigation processes, based on the technical merits of the position. The tax benefit to be recognized in the consolidated financial statements from such a position is measured as the largest amount of benefit that has a greater than 50% likelihood of being realized upon ultimate settlement. The Company reevaluates these uncertain tax positions on a quarterly basis. This evaluation is based on factors including, but not limited to, changes in facts or circumstances and changes in tax law. The Company recognizes penalties and tax-related interest expense as a component of income tax expense in the consolidated statements of operations and comprehensive loss.

Asset Retirement Obligations

The Company records an asset retirement obligation for the fair value of legal obligations associated with the retirement of tangible long-lived assets and a corresponding increase in the carrying amount of the related asset in the period in which the obligation is incurred. In periods subsequent to initial measurement, the Company recognizes changes in the liability resulting from the passage of time and revisions to either the timing or the amount of the original estimate. Over time, the liability is accreted to its present value and the capitalized cost is depreciated over the estimated useful life of the asset. The Company’s obligations relate primarily to certain legal obligations to remediate leased property on which certain assets are located. The liability is recorded in Other accrued liabilities and Other long-term liabilities in the consolidated balance sheets.

Warranty Expense

The Company warranties its products against certain defects and the terms range from one to three years. The Company provides for the estimated costs of fulfilling its obligations under hardware warranties at the time the related revenue is recognized. The Company estimates the provision based on historical and projected product failure rates, historical and projected repair costs, and knowledge of specific product failures (if any). The Company regularly reassess its estimates to determine the adequacy of the recorded warranty liability and adjusts the provision, as necessary. See Note 3: Balance Sheet Information, for further information.

Debt Issuance Costs

Debt issuance costs for the Term Loans are recorded as a reduction to the carrying amount and are amortized over their terms using the effective interest method. Amortization of these debt issuance costs is included in interest expense. See Note 4: Debt, for further information.

Stock-Based Compensation

The Company classifies stock-based awards granted in exchange for services as either equity awards or liability awards. The classification of an award as either an equity award or a liability award is generally based upon cash settlement options. Equity awards are measured based on the fair value of the award at the grant date. The Company recognizes stock-based compensation on a straight-line basis over the award’s requisite service period, which is generally the vesting period of the award, less actual forfeitures. No compensation expense is recognized for awards for which participants do not render the requisite services. For equity and liability awards earned based on performance or upon occurrence of a contingent event, when and if the awards will be earned is estimated. If an award is not considered probable of being earned, no amount of stock-based compensation is recognized. If the award is deemed probable of being earned, related compensation expense is recorded over the estimated service period. To the extent the estimate of awards considered probable of being earned changes, the amount of stock-based compensation recognized will also change. We account for forfeitures as they occur for all stock-based awards.

Concentration of Credit Risk

The Company sells products to customers in a wide variety of industries on a worldwide basis. In countries or industries where the Company is exposed to material credit risk, the Company may require collateral, including cash deposits and letters of credit, prior to the completion of a transaction. The Company does not believe it has significant credit risk beyond that provided for in the consolidated financial statements in the ordinary course of business.

Table of Contents

In fiscal 2026, one customer represented more than 10% of total revenues and in fiscal 2025 no customer represented more than 10% of the Company's total revenue.

No customer comprised over 10% of accounts receivable as of March 31, 2026 and March 31, 2025.

If the Company is unable to obtain adequate quantities of the inventory needed to sell its products, the Company could face cost increases or delays or discontinuations in product shipments, which could have a material adverse effect on the Company’s results of operations. In many cases, the Company’s chosen vendor may be the sole source of supply for the products or parts they manufacture, or services they provide, for the Company. Some of the products the Company purchases from these sources are proprietary or complex in nature, and therefore cannot be readily or easily replaced by alternative sources.

In fiscal 2026 two vendors represented more than 10% of total expenses and in fiscal 2025 two vendors represented more than 10% of our total expenses.

Segment Reporting

The Company’s chief operating decision-maker ("CODM") is its Chief Executive Officer who makes resource allocation decisions and assesses performance based on financial information presented on a consolidated basis. The CODM reviews and utilizes consolidated financial information, including revenue, gross profit, operating income and net income as reported on the consolidated statements of operations and comprehensive loss, to assess performance and allocate resources to support strategic priorities. Consolidated net loss is our segment's primary measure of profit or loss. The measure of segment assets is reported on the consolidated balance sheets as total consolidated assets. There are no segment managers who are held accountable by the CODM, or anyone else, for operations, operating results, and planning for levels or components below the consolidated unit level. Accordingly, the Company has one reportable segment and operates in three geographic regions: (a) Americas; (b) Europe, Middle East, and Africa (“EMEA”); and (c) Asia Pacific (“APAC”). See Note 12: Segment Information, for more information.

Defined Contribution Plan

The Company sponsors a qualified 401(k) retirement plan for its U.S. employees. The plan covers substantially all employees who have attained the age of 18. Participants may voluntarily contribute to the plan up to the maximum limits established by Internal Revenue Service regulations. For the years ended March 31, 2026 and 2025, the Company incurred $0.1 million and $0.3 in matching contributions, respectively. The Company suspended its program of matching contributions under the 401(k) retirement plan as of July 2024.

The Company has other defined contribution plans at its international subsidiaries, as required by local law.

Recently Adopted Accounting Pronouncements

In December 2023, the Financial Account Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which includes amendments that further enhance income tax disclosures, primarily through standardization and disaggregation of rate reconciliation categories and income taxes paid by jurisdiction. The amendments are effective for annual periods beginning on or after December 15, 2024, and may be applied either prospectively or retrospectively.

In fiscal 2026, Quantum revised its tax footnote disclosures upon the adoption of ASU 2023-09. The Company now applies a consistent approach to categorizing and presenting the information and provides enhanced disaggregation within the rate reconciliation. Additionally, the footnote disclosure provides further disaggregation of income taxes paid in foreign jurisdictions. The adoption of ASU 2023-09 did not have a material impact on the Company's consolidated financial statements for the fiscal year ended March 31, 2026. The Company adopted the standard on a prospective basis.

Recent Accounting Pronouncements Not Yet Adopted

In November 2024, the FASB issued ASU 2024-03, Income Statement - Reporting Comprehensive Income -Expense Disaggregation Disclosures (Subtopic220-40): Disaggregation of Income Statement Expenses, which requires additional disclosures of specific expense categories included within each expense caption presented on the Statements of Operations. The new standard can be applied on either a fully retrospective or prospective basis ASU 2024-03 will be effective for our fiscal year beginning April 1, 2027, and interim periods within our fiscal year

Table of Contents

beginning April 1, 2028, with early adoption permitted. The Company is currently evaluating the impact of this new standard on its financial statement disclosures.

In July 2025, the FASB issued ASU 2025-05, Financial Instruments—Credit Losses (Topic 326): Measurements of Credit Losses for Accounts Receivable and Contract Assets. The amendments in this update provide a practical expedient related to the estimation of expected credit losses for current accounts receivable and current contract assets that arise from transactions accounted for under FASB Accounting Standards Codification 606. Under ASU 2025-05, an entity is required to disclose whether it has elected to use the practical expedient. An entity that makes the accounting policy election is required to disclose the date through which subsequent cash collections are evaluated. ASU 2025-05 is effective for the Company beginning in the fiscal year beginning April 1, 2026,with early adoption permitted. The Company is currently evaluating the impact of this new standard on its financial statement disclosures.

In September 2025, the FASB issued ASU 2025-06, Targeted Improvements to the Accounting for Internal-Use Software” (Topic 350). The updates eliminate references to software development project stages and revises the criteria that must be met to begin capitalizing internal-use software costs. The standard permits entities to adopt the guidance using a prospective, retrospective, or modified transition approach and becomes effective for the Company beginning January 1, 2028, with early adoption permitted. The Company is currently assessing the potential impact that ASU 2025-06 will have on its financial statements disclosures.

In December 2025, the FASB issued ASU 2025-11, Interim Reporting (Topic 270): Narrow-Scope Improvements, which clarifies certain aspects of interim reporting guidance. The standard is effective for interim periods within fiscal years beginning after December 15, 2027, which will be the Company’s fiscal year beginning April 1, 2029, with early adoption permitted. The Company is currently evaluating the impact of this guidance on its interim financial statements disclosures.

(1) The unamortized debt issuance costs related to the Term Loan are presented as a reduction of the carrying amount of the corresponding debt balance on the accompanying consolidated balance sheets. Unamortized debt issuance costs related to the PNC Credit Facility are presented within other assets on the accompanying consolidated balance sheets.

On August 5, 2021, the Company entered into a Term Loan Credit and Security Agreement (the “Term Loan Credit Agreement”), pursuant to which a senior secured term loan was issued (the “2021 Term Loan”), maturing on August 5, 2026. The Company also entered into an Amended and Restated Revolving Credit and Security Agreement on December 27, 2018 (the “PNC Credit Facility” and, together with the Term Loan Credit Agreement, the “Credit Agreements”), which, per its terms, was maturing on August 5, 2026 and provided for borrowings up to a maximum principal amount of the lesser of: (a) $40.0 million or (b) the amount of the borrowing base, as defined in the PNC Credit Facility agreement.

On June 1, 2023, the Company entered into amendments to the Credit Agreements (the “June 2023 Amendment”) which, among other things, provided an advance of $15.0 million in additional term loan borrowings (the “2023 Term Loan” and, together with the 2021 Term Loan, the "Term Loan") and incurred $0.9 million in original issuance discount and origination fees which have been recorded as a reduction to the carrying amount of the 2023 Term Loan and amortized to interest expense over the term of the loan. The terms of the 2023 Term Loan are substantially similar to the terms of the 2021 Term Loan, including in relation to maturity and security, except that, among other things, (a) the Applicable Margin (i) for any 2023 Term Loan designated an “ABR Loan” is 9.00% per annum and (ii) for any 2023 Term Loan designated as a “SOFR Loan” is 10.00% per annum, (b) accrued interest on the 2023 Term Loan is payable in kind ("PIK"), and is capitalized and added to the principal amount of the 2023 Term Loan at the end of each interest period applicable thereto, (c) the 2023 Term Loan does not amortize prior to the maturity date thereof, and (d) the 2023 Term Loan may not be prepaid prior to the payment in full of the existing term loans. In connection with the 2023 Term Loan, the Company issued warrants to purchase an aggregate of 62,500 shares (the “June 2023 Warrants”) of the Company’s common stock, at an exercise price of $20.00 per share.

On July 11, 2024, the Company entered into amendments to the Credit Agreements (the “July 2024 Amendments”) which, among other things, delayed the testing of the Company’s June 30, 2024 net leverage ratio financial covenant until July 31, 2024. In connection with the amendments, the Company issued the Term Loan lenders warrants to purchase an aggregate of 50,000 shares of the common stock at a purchase price of $8.20 (the “July 2024 Warrants”).

The July 2024 Amendments to the 2021 Term Loan were accounted for as a modification. The fair value of the July 2024 Warrants of $0.4 million is reflected as a reduction to the carrying amount of the 2021 Term Loan and amortized to interest expense over the remaining term of the loan. The July 2024 Amendments to the PNC Credit Facility were accounted for as a modification and the $0.1 million in related fees and expenses were recorded to other assets and are amortized to interest expense over the remaining term of the agreement.

On August 13, 2024, the Company entered into amendments to the Credit Agreements (the “August 2024 Amendments”) which, among other things, (i) waived compliance with the June 30, 2024 net leverage ratio financial covenant; (ii) waived any non-compliance with the minimum liquidity financial covenant through the date of the amendments; (iii) removed the fixed charges coverage ratio financial covenant until the fiscal quarter ended September 30, 2025; (iv) waived the testing requirement for the net leverage ratio financial covenant for the fiscal quarter ended September 30, 2024; (v) replaced the net leverage ratio financial covenant with a minimum EBITDA financial covenant for the fiscal quarters ended December 31, 2024 and March 31, 2025; (vi) reset the net leverage ratio financial covenant requirements for the fiscal quarters ended June 30, 2025 and September 30, 2025; (vii) reduced the minimum liquidity covenant to $10 million through September 30, 2025; (viii) adjusted the applicable interest rates on the Term Loan and PNC Credit Facility; (ix) removed required 2021 Term Loan principal amortization until the fiscal quarter ended September 30, 2025; and (x) repriced certain lender warrants.

In connection with the August 2024 Amendments, the Company entered into a new senior secured delayed draw term loan facility with a borrowing capacity of up to $26.3 million ($25.0 million after original issuance discount) and a commitment period expiring on October 31, 2024 (each draw, an “August 2024 Term Loan”). The Company borrowed $10.5 million at closing (“Initial August 2024 Term Loan”). Borrowings under the August 2024 Term Loan have an August 5, 2026 maturity date, which aligns with the 2021 Term Loan. The principal is payable quarterly beginning September 30, 2025, at a rate per annum equal to 5% of the original principal balance. The August 2024 Term Loan’s interest rate margin is (a) until March 31, 2025 (i) for any August 2024 Term Loan designated as a ‘SOFR Loan’, 12.00% per annum and (ii) for any August 2024 Term Loan designated an ‘ABR Loan’, 11.00% per annum, in each case, with 6.00% of such interest rate margin paid-in-kind, and (b) from April 1, 2025, (i) for any

Table of Contents

August 2024 Term Loan designated as a ‘SOFR Loan’, 14.00% per annum and (ii) for any August 2024 Term Loan designated an ‘ABR Loan’, 13.00% per annum, in each case, with 8.00% of such interest rate margin paid-in-kind. The August 2024 Term Loan also includes a multiple on invested capital payable to the August 2024 Term Loan lenders. Subsequently, the Company borrowed the remaining $15.8 million of the August 2024 Term Loan’s borrowing capacity before September 30, 2024.

Subsequent to the August 2024 Amendments, the 2021 Term Loan amortizes at 5.00% per annum commencing on September 30, 2025. Subsequent to the August 2024 Amendments and (A) until March 31, 2025, loans under the 2021 Term Loan designated as ABR Loans bear interest at a rate per annum equal to the “ABR Rate” (calculated as the greatest of (i) 1.75%; (ii) the Federal funds rate plus 0.50%; (iii) a secured overnight financing rate (the “SOFR Rate”) based upon an interest period of one month plus 1.0%; and (iv) the “Prime Rate” last quoted by The Wall Street Journal), plus an applicable margin of 8.75%, and (y) SOFR Rate Loans bear interest at a rate per annum equal to the SOFR Rate plus an applicable margin of 9.75%, in each case, with 3.75% of such interest rate margin paid-in-kind, with two specified step-downs in such applicable margin upon the receipt by the Company of cash proceeds from certain specified capital raises, and (B) from and after April 1, 2025, loans under the 2021 Term Loan designated as (x) ABR Loans bear interest at a rate per annum equal to the ABR Rate, plus an applicable margin of 8.75%, and (y) SOFR Rate Loans bear interest at a rate per annum equal to the SOFR Rate plus an applicable margin of 9.75%, in each case, with 3.75% of such applicable margin paid-in-kind, with a step-up of 1.00% per annum (which shall be paid-in-kind) if the Company’s total net leverage ratio is greater than 4.00x, and a step-down of 1.00% per annum if the Company’s total net leverage ratio is less than 3.50x (which shall reduce the paid-in-kind component of the applicable margin). The SOFR Rate is subject to a floor of 2.00%. The Company can designate a loan as an ABR Rate Loan or SOFR Rate Loan in its discretion.

Subsequent to the August 2024 Amendments, PNC Credit Facility loans designated as (x) PNC SOFR Loans bear interest at a rate per annum equal to a SOFR based rate, plus an applicable margin of 4.75% and (y) PNC Domestic Rate Loans and Swing Loans bear interest at a rate per annum equal to the greatest of (i) the base commercial lending rate of PNC Bank; (ii) the Overnight Bank Funding Rate plus 0.5%; and (iii) the daily SOFR rate plus 1.0%, plus an applicable margin of 3.75%. The Company can designate a loan as a PNC SOFR Loan or PNC Domestic Rate Loan in its discretion.

In connection with the August 2024 Amendments, the Company issued warrants to purchase an aggregate of 380,310 shares of common stock, at an exercise price of $6.20 per share (the “August 2024 Warrants”) and which had a fair value of $2.0 million.

The August 2024 Amendments to the 2021 Term Loan held by one lender was accounted for as a modification. The $1.2 million fair value of the August 2024 Warrants issued to this lender and the $0.5 million of PIK fees paid to this lender are reflected as a reduction to the carrying amount of their Term Loan and their initial delayed draw term loan and amortized to interest expense over the remaining term of the loan. The August 2024 Amendments to the 2021 Term Loan held by another lender was accounted for as a debt extinguishment. The Company recorded a loss on debt extinguishment of $3.0 million related to the write-off of a portion of unamortized debt issuance costs and fees and expenses incurred with the August 2024 Amendments.

On April 2, 2025, the Company consented to an assignment (the “Master Assignment Agreement”) of the 2021 Term Loan and 2024 Term Loans. One of the lenders sold $51.4 million of Term Loan and assigned all of its interests to Dialectic Technology SPV, LLC (“Dialectic”). The Master Assignment Agreement was accounted for as a debt extinguishment. The Company recorded a gain on debt extinguishment of $2.4 million related to the net of discount on issuance of term loans to a new lender and write-off of all unamortized debt issuance costs and fees related to the previous lender. The $0.4 million in new lender fees were recorded as a reduction to the carrying amounts of the term loans and amortized to interest expense over the remaining term of the loan.

On May 5, 2025, the Company entered into an amendment (the “May 2025 Term Loan Amendment”) to the Term Loan. The May 2025 Term Loan Amendment, among other things, revised the prepayment requirements under the Term Loan Credit Agreement in connection with the net cash proceeds received from the SEPA. The May 2025 Term Loan Amendment was accounted for as a modification and the $0.1 million in lender amendment fees were recorded as a reduction to the carrying amounts of the term loans and amortized to interest expense over the remaining term of the loan.

On August 13, 2025, the Company terminated its PNC Credit Facility. As of the date of termination, there were no amounts outstanding under the facility. In connection with the termination, the Company paid an exit fee of

Table of Contents

$1.2 million, which was recorded within Loss on Debt Extinguishment on the consolidated statement of operations and comprehensive loss.

On August 13, 2025, the Company obtained waivers to certain covenants including the net leverage covenant under the Term Loan Credit Agreement for the quarter ended June 30, 2025. Additionally, the requirement to use certain proceeds of the SEPA to pay down the Term Loan was waived.

On September 23, 2025, the Company entered into the Fifteenth Amendment to the Term Loan Credit Agreement with Quantum LTO Holdings, LLC, Dialectic, OC III LVS XXXIII LP (“LVS XXXIII”), OC III LVS XL LP (“LVS XL” and together with LVS XXXIII, the “OC III Lenders”), and Alter Domus (US) LLC, as disbursing agent and collateral agent (the “Fifteenth Amendment”). The Fifteenth Amendment, among other things, (i) permits the Company to retain up to $15.0 million of net cash proceeds from the SEPA received on or after the date of the Fifteenth Amendment for working capital and general corporate purposes, (ii) converts certain tranches of Term Loans held by the OC III Lenders into new and separate tranches, (iii) defers payment of cash interest on Term Loans held by Dialectic accruing during the quarters ended September 30, 2025 and December 31, 2025, until the earliest of (a) the date the Company elects to pay such deferred cash interest, (b) the maturity of such term loans, or (c) the date the Debt Exchange (as defined below) occurs, at which point such deferred interest will be subject to the terms of the Convertible Note indenture, and increases the interest rate applicable to such term loans by 2.00% during the period that such cash interest is being deferred, (iv) eliminates the existing maximum total net leverage ratio covenant and minimum daily liquidity covenant (noting that, following the Debt Exchange (as defined below), the Convertible Note will be subject to a minimum liquidity covenant), and (v) amends certain other provisions, including mandatory prepayment events, payment of fees and expenses, and reporting requirements.

In connection with the Fifteenth Amendment, the Company issued a warrant (the “Forbearance Warrant”) to Dialectic to purchase up to 2,653,308 shares of its common stock, representing 19.9% of the Company’s outstanding shares as of the date of the Transaction Agreement (as defined below) as consideration for the forbearance, waivers, and amendments granted under the Fifteenth Amendment. See Note 7: Common Stock, for additional information.

With respect to the Term Loans held by Dialectic, the Fifteenth Amendment was accounted for as an extinguishment under ASC 470-50, resulting in the recognition of a new debt instrument, the derecognition of the original term loans, and a loss on extinguishment of $31.0 million, which is included in loss on debt extinguishment on the consolidated statement of operations and comprehensive loss for fiscal year ended March 31, 2026. The fair value of the Forbearance Warrant was treated as a lender fee and included in the extinguishment loss calculation. The Fifteenth Amendment to the Term Loans held by OC III Lenders was accounted for as a modification. See Note 11: Fair Value of Financial Instruments, for additional information.

On September 23, 2025, the Company entered into an agreement with Dialectic and the OC III Lenders (the “Transaction Agreement”). Pursuant to the Transaction Agreement, the Company agreed to issue to Dialectic, on a dollar-for-dollar basis, one or more 10.00% PIK Senior Secured Convertible Notes due 2028 ("Convertible Note") in exchange for the amounts then outstanding under the term loans held by Dialectic (the “Debt Exchange”). On December 18, 2025, the Company closed the transactions contemplated by the Transaction Agreement (the “Closing”), including its issuance to Dialectic of the Convertible Note and extinguishing $54.7 million of Term Debt. Associated lender fees of $2.2 million were also incurred. The Closing was conditioned upon, among other things, approval of the Debt Exchange by the Company’s stockholders, which approval was obtained on December 16, 2025.

The Convertible Note has a three-year maturity and bears interest at 10% per annum, payable in kind and compounded annually. The Convertible Note is secured by substantially all of the assets of the Company that secure the Term Loan. The initial conversion price equals $10.00 per share of the Company’s common stock (the “Conversion Price”). The Conversion Price is subject to four quarterly resets on the last day of each calendar quarter immediately following September 15, 2025 (each, a “Reset Price Date”) to the greater of (a) $4.00 per share and (b) the lesser of (i) the then-current Conversion Price and (ii) the 30-day Volume-Weighted Average Price (VWAP) of the Company’s common stock immediately preceding the Reset Price Date.

The Lender may, at any time, elect to exchange all or any portion of the outstanding principal amount, accrued and unpaid interest and premium (if any) of the Convertible Note for shares of the Company’s common stock at the then-applicable Conversion Price. Beginning six months after the Closing, if certain conditions are met, the Company may, at its election, require the Lender to exchange a portion of the outstanding Convertible Note into shares of the Company’s common stock at the then-applicable Conversion Price if the 10-day VWAP exceeds specified multiples of the Conversion Price (the “Company Mandatory Exchange”). The Company Mandatory

Table of Contents

Exchange, if triggered, occurs in tranches of 20%, 20%, 30%, and the remaining balance. If certain conditions are met, at the Company’s option, on the maturity date, any outstanding principal, accrued and unpaid interest, and premium (if any) may be exchanged for shares of the Company’s common stock at 80% of the average of the Daily VWAP for each of the five lowest consecutive trading days during the 20 consecutive trading days ending on (and including) the trading day immediately prior to the maturity date.

The Company accounted for the exchange of Dialectic’s term loans for the Convertible Note as an extinguishment of the term loans and recognized a loss on debt extinguishment of $28.9 million on the consolidated statement of operations and comprehensive loss for the fiscal year ended March 31, 2026. The Company elected the fair value option under ASC 825 for the Convertible Note. See Note 11: Fair Value of Financial Instruments, for additional information.

Related Party Transactions

The Forbearance Warrant and Convertible Note issued to Dialectic constitute related party transactions, as John Fichthorn, a member of the Company's Board, is also Managing Partner of Dialectic Capital Management, the investment adviser to Dialectic. On issuance of the Convertible Note, Quantum paid $1.1 million to Dialectic for consulting services. The fair values of the Forbearance Warrant and Convertible Note as of March 31, 2026 are included in Note 11: Fair Value of Financial Instruments.

During fiscal 2026, the Company granted equity awards to its Chief Executive Officer including options to purchase 100,000 shares of the Company’s common stock, one award for 50,000 in November 2025 with a grant date fair value of $7.39 per share and the other award for 50,000 in January 2026 which had a grant date fair value if $5.02 per share. Both awards vest in four equal annual installments, subject to continued service. The stock option was valued using the Black-Scholes option pricing model on the grant date.

The significant assumptions used by the Company to estimate the fair value of the option awards as of March 31, 2026 are summarized below:


	November 1, 2025	January 1, 2026
Term (years)	7.00 years	7.00 years
Volatility 1	100.2%	98.8%
Dividend yield 2	0.00%	0.00%
Risk-free interest rate 3	3.66%	3.79%
Grant date fair value	$7.39	$5.02

1 Volatility is based of the Company's historical stock price over a period of the expected term of the options.

2 Dividend yield is set to —% as the Company has not historically paid dividends.

3 Risk-free interest rate is based on the Treasury yield for the expected term of the options.

The negative stock compensation expense in fiscal 2026 is largely driven by separations during the period.

Warrants

In connection with various debt refinancing and debt amendment activities detailed in Note 4: Debt, the Company issued warrants to purchase shares of the Company common stock. As of March 31, 2026, there was a Forbearance Warrant issued in September 2025 which are exercisable until the seventh anniversary of its issuance. As of March 31, 2024, there were Lender Warrants that were issued in December 2018 which were exercisable until December 27, 2028, issued in June 2020 which were exercisable until June 16, 2030 and issued in June 2023 which were exercisable until June 1, 2033 (collectively the "Lender Warrants"). The Lender Warrants were fully exercised in fiscal 2025.

Lender Warrants

On December 30, 2024, 467,248 warrants were exercised in a cashless exercise whereby 61,270 shares with a value of $6.20 per share were used to settle the exercise price and the remaining 405,978 shares were issued to the warrant holders.

On January 3, 2025, certain PIMCO-managed entities exercised 677,905 warrants in a cashless exercise whereby 228,195 shares with a weighted-average value of $35.42 per share were used to settle the exercise price and the remaining 449,710 shares were issued to the warrant holders. As PIMCO was a related party, this transaction was reviewed and approved in accordance with the Company’s related party transaction policy.

The table below sets forth a summary of changes in the fair value of the Company’s Level 2 Lender Warrant liabilities for the years ended March 31, 2024 and March 31, 2025. The Company did not issue any Lender Warrants during the year ended March 31, 2026 and had no outstanding Lender Warrants as of March 31, 2026.

Forbearance Warrant

The Forbearance Warrant, issued on September 23, 2025, has an exercise price of $8.81 per share, representing 80% of the seven-day volume-weighted average price as of September 22, 2025, and is exercisable until the seventh anniversary of its issuance. It includes a put right that allows the holder to require the Company to repurchase the unexercised portion for cash after the fifth anniversary, or earlier upon a change of control or

Table of Contents

liquidation. The repurchase price equals the holder’s pro rata share of the original issue value of $20 million, adjusted for any exercised portion.

The Forbearance Warrant is classified as a liability under ASC 480, as it may require cash settlement and meets the definition of a derivative. It is initially measured at fair value, with subsequent changes recognized in the consolidated statements of operations and comprehensive loss under “Change in fair value of warrant liabilities.” See Note 11: Fair Value of Financial Instruments, for additional information.

The table below sets forth a summary of changes in the fair value of the Company’s Level 2 Forbearance Warrant liabilities for the years ended March 31, 2026 and March 31, 2025:

Issuance of warrants	25,420
Change in fair value of warrant liabilities	(11,315)

Other Warrants

The Company also issued 2,500 warrants to purchase the Company's common stock in June 2020 and June 2023 to advisors of the Company at an exercise price of $60.00 and $20.00, respectively (collectively the "Other Warrants"). The Company has concluded that the Other Warrants do not contain provisions that would require liability classification under Topic 480 or Topic 718 and have been equity classified.

Standby Equity Purchase Agreement

On January 25, 2025, we entered into the SEPA with YA in which pursuant to and subject to its terms, the Company has the right, but not the obligation, to sell up to $200.0 million of common stock at any time during the three-year period following the date of the SEPA. On January 27, 2025, the Company filed a registration statement on Form S-1 in connection with the SEPA. The Registration Statement on Form S-1 was declared effective February 11, 2025.

Sales of common stock under the SEPA may be made by the Company at its discretion from time to time and will depend upon market conditions and other factors. The purchase price for shares sold under the SEPA is based on a formula tied to the volume-weighted average price of the Company’s common stock.

In addition, in no event may the Company issue more than 1,157,139 shares of common stock under the SEPA, representing 19.99% of the Company’s common stock outstanding immediately prior to execution of the SEPA (the “Exchange Cap”), unless the Company obtains stockholder approval in accordance with applicable Nasdaq rules or otherwise satisfies the conditions under which the Exchange Cap would not apply. The SEPA is also subject to a 4.99% beneficial ownership limitation, which restricts YA from acquiring shares that would result in ownership above that threshold.

As of March 31, 2026, the Company has issued approximately 8.7 million shares of common stock under the SEPA for net proceeds of approximately $91.0 million with 7.6 million shares sold in fiscal 2026 for net proceeds of $75.2 million.

The amount of additional capital that may be raised under the SEPA will depend on market conditions, trading volumes, the Company’s stock price, and the continued satisfaction of the applicable limitations and conditions under the agreement.

The Company evaluated the SEPA that includes the right to require YA to purchase shares of common stock in the future (“put right”) considering the guidance in ASC 815-40, Derivatives and Hedging — Contracts on an Entity’s Own Equity, and concluded that it is an equity-linked contract that does not qualify for equity classification, and therefore requires fair value accounting. The Company has analyzed the terms of the freestanding put right and has concluded that it has an immaterial value as of March 31, 2026 and 2025.

Registration Rights Agreements

Pursuant to the registration rights agreements applicable to the Lender Warrants, the holders have certain registration rights for the shares of common stock issuable upon exercise of the applicable warrants, including (a) the ability of a holder to request that the Company file a Form S-1 registration statement with respect to at least

Table of Contents

40% of the registrable securities held by such holder as of the issuance date of the applicable warrants; (b) the ability of a holder to request that the Company file a Form S-3 registration statement with respect to outstanding registrable securities if at any time the Company is eligible to use a Form S-3 registration statement; and (c) certain piggyback registration rights related to potential future equity offerings of the Company, subject to certain limitations.

The registration rights agreement dated September 23, 2025, by and between the Company and Dialectic, grants Dialectic certain registration rights with respect to the shares of common stock issuable upon exercise of the Forbearance Warrant, including certain mandatory resale registration and piggyback registration rights, subject to certain limitations.

In addition, the registration rights agreement dated December 18, 2025, by and between the Company and Dialectic, grants Dialectic certain registration rights with respect to the shares of common stock issuable upon conversion of the Convertible Note, including certain mandatory resale registration and piggyback registration rights, subject to certain limitations.

NOTE 8: NET LOSS PER SHARE

Equity Instruments Outstanding

The Company has stock options, warrants, performance share units and restricted stock units granted under various stock incentive plans that, upon exercise and vesting, would increase shares outstanding.

The following table sets forth the computation of basic and diluted net loss (in thousands, except per share data):


	Year Ended March 31,
	2026		2025
Numerator:
Net loss used in basic and diluted earnings per share	$	(101,046)	$	(115,091)




Denominator:
Weighted average common shares outstanding used in basic and diluted earnings per share	12,674		5,150




Net income loss per share - basic and diluted	$	(7.97)	$	(22.35)

The dilutive impact related to shares of common stock from incentive plans and outstanding warrants is determined by applying the treasury stock method to the assumed vesting of outstanding performance share units and restricted stock units and the exercise of outstanding options and warrants. The dilutive impact related to shares of common stock from contingently issuable performance share units is determined by applying a two-step approach using both the contingently issuable share guidance and the treasury stock method.

The following weighted-average outstanding shares of common stock equivalents were excluded from the computation of diluted net loss per share attributable to common stockholders for the periods presented because including them would have been anti-dilutive (in thousands):


	Year Ended March 31,

Stock awards1	62	127
Warrants	2,653	634

Total	2,715	761

1 Stock awards include stock options, performance share units and restricted stock units

The Company had outstanding market based restricted stock units as of March 31, 2026 and 2025 that were eligible to vest into shares of common stock subject to the achievement of certain stock price targets in addition to a time-based vesting period. These contingently issuable shares are excluded from the computation of diluted earnings per share if, based on current period results, the shares would not be issuable if the end of the reporting period were the end of the contingency period. There were 30,517 and 186,616 shares of contingently issuable market-based restricted stock units that were excluded from the table above as the market conditions were not satisfied as of March 31, 2026 and 2025, respectively.

During fiscal 2026, excluding interest and penalties, there was a $(5.1) million change in the Company's unrecognized tax benefits. Including interest and penalties, the total unrecognized tax benefit at March 31, 2026 was $77.8 million, of which $68.8 million, if recognized, would favorably affect the effective tax rate. At March 31, 2026, accrued interest and penalties totaled $1.2 million. The Company's practice is to recognize interest and penalties related to income tax matters in the income tax provision in the consolidated statements of operations and comprehensive loss. As of March 31, 2026, $70.9 million of unrecognized tax benefits were recorded as a contra deferred tax asset in other long-term assets in the consolidated balance sheets and $6.9 million (including interest and penalties) were included in other long-term liabilities in the consolidated balance sheets.

The Company files its tax returns as prescribed by the laws of the jurisdictions in which it operates. The Company's U.S. tax returns have been audited for years through 2002 by the Internal Revenue Service. In other major

Table of Contents

jurisdictions, the Company is generally open to examination for the most recent three to five fiscal years. During the next 12 months, it is reasonably possible that approximately $2.6 million of tax benefits, inclusive of interest and penalties, that are currently unrecognized could be recognized as a result of the expiration of applicable statutes of limitations. Upon recognition of the tax benefit related to the expiring statutes of limitation, $1.7 million will be offset by the establishment of a related valuation allowance. The net tax benefit recognized in the consolidated statements of operations and comprehensive loss is estimated to be $0.9 million.

As of March 31, 2026, the Company had federal net operating loss and tax credit carryforwards of approximately $324.8 million and $26.7 million, respectively. The net operating loss and tax credit carryforwards expire in varying amounts in fiscal 2026 if not previously utilized, and $151.5 million are indefinite-lived net operating loss carryforwards. These carryforwards include $5.3 million of acquired net operating losses, the utilization of which is subject to various limitations due to prior changes in ownership.

Certain changes in stock ownership could result in a limitation on the amount of both acquired and self-generated net operating loss and tax credit carryovers that can be utilized each year. If the Company has previously undergone, or should it experience in the future, such a change in stock ownership, it could severely limit the usage of these carryover tax attributes against future income, resulting in additional tax charges.

Due to its history of net losses and the difficulty in predicting future results, Quantum believes that it cannot rely on projections of future taxable income to realize the deferred tax assets. Accordingly, it has established a full valuation allowance against its U.S. and certain foreign net deferred tax assets. Significant management judgment is required in determining the Company's deferred tax assets and liabilities and valuation allowances for purposes of assessing its ability to realize any future benefit from its net deferred tax assets. The Company intends to maintain this valuation allowance until sufficient positive evidence exists to support the reversal of the valuation allowance. The Company's income tax expense recorded in the future will be reduced to the extent that sufficient positive evidence materializes to support a reversal of, or decrease in, its valuation allowance.

NOTE 10: COMMITMENTS AND CONTINGENCIES

Commitments to Purchase Inventory

The Company uses contract manufacturers for its manufacturing operations. Under these arrangements, the contract manufacturer procures inventory to manufacture products based upon its forecast of customer demand. The Company has similar arrangements with certain other suppliers. The Company is responsible for the financial impact on the supplier or contract manufacturer of any reduction or product mix shift in the forecast relative to materials that the third party had already purchased under a prior forecast. Such a variance in forecasted demand could require a cash payment for inventory in excess of current customer demand or for costs of excess or obsolete inventory. As of March 31, 2026, the Company had issued non-cancelable commitments for $76.8 million to purchase inventory from its contract manufacturers and suppliers.

Legal Proceedings

From time to time, we are a party to various legal proceedings and claims arising from the normal course of business activities. Based on current available information, we do not expect that the ultimate outcome of any additional currently pending unresolved matters, individually or in the aggregate, will have a material adverse effect on our results of operations, cash flows or financial position.

Litigation

Shareholder Litigation

On September 4, 2025, a shareholder class action complaint was filed in the United States District Court for the District of Colorado. The complaint identifies Seung Lee as the plaintiff and names Quantum Corporation and James J. Lerner, Kenneth P. Gianella, and Laura Nash as defendants. It alleges violations of Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and SEC Rule 10b-5 related to certain disclosures made in the Company’s quarterly and annual reports regarding its financial reporting for the third quarter of the Company’s fiscal year 2025 and its restatement of that financial reporting. The complaint sought to designate the plaintiff as the lead plaintiff for the class and define a class period of November 15, 2024 through August 18, 2025. On January 27, 2026, a revised final complaint named Hunsu Son as the lead plaintiff and reiterated the violations alleged in the original complaint. The revised complaint seeks an award of unspecified damages, costs, and expenses. The Company has filed a motion to dismiss the litigation. Briefing of that motion is underway. At this time, Quantum is not

Table of Contents

able to determine whether this lawsuit would have any material adverse effect on our business, operating results, or financial condition.

Derivative Litigation

On October 28, 2025, a shareholder derivative complaint was filed in the United States District Court for the District of Colorado. The complaint was filed by Brent Cullison derivatively on behalf of Quantum Corporation against James J. Lerner, Kenneth P. Gianella, Laura Nash, Don Jaworski, John Fichthorn, Hugues Meyrath, John R. Tracy, Emily White, James C. Clancy, and Tony J. Blevins. The complaint substantially repeats the allegations of the shareholder litigation described above and alleges related breaches of fiduciary duties and other causes of action. The complaint seeks recovery of damages sustained by Quantum arising from the allegations, as well as fees and costs incurred.

Another shareholder derivative complaint was filed in the same court on November 4, 2025. That complaint names Felicia Marti on behalf of Quantum Corporation as the plaintiff, with James J. Lerner, Kenneth P. Gianella, Laura Nash, John Fichthorn, Donald J. Jaworski, Hugues Meyrath, John R. Tracy, and Emily White named as defendants.The complaint substantially repeats the allegations of the Cullison derivative litigation and seeks relief of recovery of damages sustained by Quantum arising from the allegations, certain corporate governance reforms, and fees and costs incurred.

The court ordered the separate Cullison and Marti shareholder derivative complaints to be consolidated and stayed pending final resolution of the motion to dismiss the amended complaint in the Lee shareholder class action litigation. At this time, Quantum is not able to determine whether the consolidated lawsuits would have any material impact on our business, operating results, or financial condition.

Leases

At the end of fiscal 2026, the Company had various non-cancelable operating leases for office facilities. Refer to Note 5: Leases, for additional information regarding lease commitments.

NOTE 11: FAIR VALUE OF FINANCIAL INSTRUMENTS

The Company follows the guidance in ASC 820, Fair Value Measurement, for its financial assets and liabilities that are re-measured and reported at fair value at each reporting period and non-financial assets and liabilities that are re-measured and reported at fair value at least annually. The Company has certain non-financial assets that are measured at fair value on a non-recurring basis when there is an indicator of impairment, and they are recorded at fair value only when an impairment is recognized. These assets include property and equipment and amortizable intangible assets. The Company did not record impairments to any non-financial assets in the fiscal years ended March 31, 2026 and 2025.

The fair value of the Company’s financial assets and liabilities reflects management’s estimate of amounts that the Company would have received in connection with the sale of the assets or paid in connection with the transfer of the liabilities in an orderly transaction between market participants at the measurement date. In connection with measuring the fair value of its assets and liabilities, the Company seeks to maximize the use of observable inputs (market data obtained from independent sources) and to minimize the use of unobservable inputs (internal assumptions about how market participants would price assets and liabilities). The following fair value hierarchy is used to classify assets and liabilities based on the observable inputs and unobservable inputs used in order to value the assets and liabilities:

Level 1: Quoted prices in active markets for identical assets or liabilities. An active market for an asset or liability is a market in which transactions for the asset or liability occur with sufficient frequency and volume to provide pricing information on an ongoing basis.

Level 2: Observable inputs other than Level 1 inputs. Examples of Level 2 inputs include quoted prices in active markets for similar assets or liabilities and quoted prices for identical assets or liabilities in markets that are not active.

Level 3: Unobservable inputs based on management’s assessment of the assumptions that market participants would use in pricing the asset or liability.

Table of Contents

Information related to the fair value of the Company's warrant liabilities and Convertible Note, which were determined utilizing Level 2 inputs to determine such fair value, are included in Note 4: Debt.

The following table represents the carrying value and total estimated fair value of the Company's Term Loan which was determined utilizing Level 2 inputs to determine fair value.


	March 31,
	2026				2025
	Carrying Value		Fair Value		Carrying Value		Fair Value

Term Loan	$	55,906	$	51,339	$	102,507	$	91,576

The carrying amounts reported in the accompanying consolidated financial statements for cash and cash equivalents, restricted cash, accounts receivable, accounts payable and other current liabilities approximate their respective fair values because of the short-term nature of these accounts.

Warrants

On September 23, 2025, the Company established the initial fair value for the Forbearance Warrant issued to Dialectic in connection with the Fifteenth Amendment. The fair value was subsequently remeasured as of March 31, 2026, and the resulting change in fair value was recognized in the consolidated statement of operations and comprehensive loss under “Change in fair value of warrant liability.”

The Forbearance Warrant was valued using a Monte Carlo simulation model in conjunction with a Probability-Weighted Expected Return Model. This model incorporates various assumptions, including the Company’s common stock price, expected volatility, risk-free interest rate, and the remaining contractual term of the warrant.

Because the valuation relies on significant unobservable inputs, the fair value of the Forbearance Warrant is classified as Level 3 within the fair value hierarchy.

The following table summarizes the key assumptions used in estimating the fair value of the Forbearance Warrant at issuance and at March 31, 2026:


	March 31, 2026	September 23, 2025
Discount period (years)	6.48 years	7.0 years
Risk-free interest rate	3.65% - 4.02%	3.52% - 3.83%
Stock price volatility	100.00%	98.00%
Stock price at valuation date	$4.75	$10.69
Probability1	15% - 15% - 70%	35% - 15% - 50%
Fair value (in thousands)	$14,105	$25,420

(1) Scenario probability as of issuance was based on timing expectations of management that a liquidation event occurring was estimated at 35%; a fundamental transaction occurring was estimated at 15%; and none of the previous events were estimated at 50% and were revised at March 31, 2026 to a 15% of a liquidation event occurring; a 15% of a fundamental transaction occurring; and none of the previous events were estimated at 70%.

Convertible Note

The Company measures the Convertible Note at fair value using significant inputs that are not observable in active markets and therefore classifies the Convertible Note as a Level 3 measurement within the fair value hierarchy.

Table of Contents

Changes in the fair value of the Convertible Note resulting from updated assumptions and estimates are recognized as a fair value adjustments in the consolidated statements of operations and comprehensive loss.

The Company estimated the fair value of the Convertible Note using a Monte Carlo simulation method, as the Convertible Note includes features for which the settlement outcome depends on the path of the Company’s common stock price and other variables over time. In addition, the Company assigned probabilities to various possible settlement scenarios.

The significant assumptions used by the Company to estimate the fair value of the Convertible Note as of December 18, 2025 and March 31, 2026 are summarized below:


	March 31, 2026	December 18, 2025

NOTE 13: SUBSEQUENT EVENTS

Private Placement

On June 1, 2026, the Company entered into Securities Purchase Agreements (the “Purchase Agreement”) with certain accredited investors (the “Investors”), pursuant to which the Company, in a private placement (the “Private Placement”), agreed to issue and sell to the Investors an aggregate of 10,615,712 shares of the Company’s common stock, par value $0.01 per share, at a price of $9.42 per share, for aggregate gross proceeds to the Company of $100.0 million. After deducting placement agent fees and other offering expenses payable by the Company, the Company received net proceeds of approximately $94.7 million. The Private Placement closed June 4, 2026 (the “Closing”).

Table of Contents

Amendment to Term Loan

On June 1, 2026, the Company entered into a Sixteenth Amendment (the “Sixteenth Amendment”) to its Term Loan Credit Agreement. Pursuant to the Sixteenth Amendment, among other things, the maturity date of the loans under the Term Loan Credit Agreement was extended to September 2028 and a portion of the proceeds of future equity issuances by the Company are allowed to be retained by the Company rather than 100% of the net proceeds having to be used to mandatorily prepay loans under the Term Loan Credit Agreement. In addition, the Sixteenth Amendment clarifies that, following the conversion or exchange of the Convertible Notes (as described below), the liens securing the Convertible Notes, and the intercreditor agreement governing the priority of those liens vis-a-vis the liens securing the obligations of the Company under the Existing Credit Agreement, will terminate, and all of the outstanding obligations under the Term Loan Credit Agreement will continue to be secured by the assets of the Company on a first priority basis.

Note Conversion Agreement

In order to facilitate the Private Placement and the Sixteenth Amendment, Dialectic, as the sole beneficial owner of the Convertible Notes, agreed to voluntarily convert the Convertible Note into common stock. Pursuant to a Conversion Agreement dated June 1, 2026 (the “Conversion Agreement”), by and among the Company, Dialectic and, solely with respect to Sections 7.1 and 7.3 and Articles III and X thereof, U.S. Bank Trust Company, National Association, as the trustee and Notes Collateral Agent under the Indenture (the “Indenture”), dated as of December 18, 2025, by and among the Company, the guarantors party thereto and U.S. Bank Trust Company, National Association, as trustee and collateral agent, on June 4, 2026, Dialectic converted the entire principal amount of the Convertible Note, together with all accrued and unpaid interest thereon, which was approximately $57.2 million, at the Closing, subject to certain conditions set forth in the Conversion Agreement (the “Conversion”). At the Closing, the Convertible Note was canceled.

As consideration for Dialectic’s agreement to voluntarily convert the Convertible Notes to facilitate the Private Placement and the Sixteenth Amendment, the Company agreed to, at the Closing, (i) amend the Convertible Note to waive certain notice and settlement requirements otherwise applicable to a voluntary exchange; (ii) issue to Dialectic approximately 3.1 million additional shares of the Company’s common stock in connection with the Conversion (the “Share Consideration”), which represents the quotient of (A) approximately $13.0 million, the present value of nominal PIK interest that would accrue on the Convertible Note from the Closing to the maturity date thereof, assuming it had remained outstanding until the end of the stated term, discounted at a rate of 11%, plus (B) approximately $3.0 million, the Term Loan Deferred Cash Interest Amount (as defined in the Term Loan Credit Agreement) owed to Dialectic, divided by $5.1940, the current conversion price of the Convertible Note; and (iii) issue to Dialectic the Conversion Warrant (as defined below).

Warrant

On June 1, 2026, as additional consideration for the Conversion, the Company issued to Dialectic a warrant (the “Conversion Warrant”) to purchase up to 105,911 shares of common stock at an exercise price of $5.1940 per share (the “Conversion Warrant Exercise Price”) (equal to the conversion price of the Convertible Note in effect following the reset period ending March 31, 2026), at any time until the fifth anniversary of the issuance of the Conversion Warrant. Upon exercise, the aggregate exercise price may be paid, at Dialectic’s election, in cash or on a net issuance basis, based upon the then current market price of the common stock at the time of exercise. The Conversion Warrant includes certain antidilution protections in favor of Dialectic, subject to certain limitations, including limitations that restrict Dialectic from beneficially owning more than 19.99% of the Company’s outstanding Common Stock and certain exclusions. Additionally, Dialectic may require the Company to repurchase the unexercised portion of the Conversion Warrant for an amount equal to $844,255, proportionately adjusted for the portion of the Conversion Warrant subject to repurchase, after the fourth anniversary of the issuance of the Conversion Warrant, or, prior to the fourth anniversary, upon a change of control of the Company or immediately prior to the occurrence of a voluntary dissolution, liquidation or winding up of the affairs of the Company.

Right of First Refusal Agreement

On June 1, 2026, the Company entered into a Right of First Refusal Agreement (the “ROFR Agreement”) with Dialectic and certain investors in the Private Placement, pursuant to which the Company granted a right of first refusal to purchase 25% of all equity securities to each investor that the Company may issue or sell for a period of the earlier of six (6) months following the date of the ROFR Agreement and completion of the Company’s next equity financing transaction, subject to certain exceptions as described in the ROFR Agreement.

Termination of Term Loan Credit Agreement

Table of Contents

On June 4, 2026, the Company paid an aggregate of $57.8 million in connection with the termination of the Term Loan Credit Agreement, consisting of the entire outstanding principal amount of $56.0 million, accrued interest of $1.5 million, and fees and expenses of $0.3 million incurred in connection with the termination.

Termination of Equity Line of Credit

On June 4, 2026, in accordance with the terms of the SEPA, the Company provided a notice to YA regarding its termination of the SEPA, effective June 11, 2026. There were no amounts owed to YA under the SEPA at the time the termination notice was provided.

Termination of Indenture

Pursuant to the terms of that the Conversion Agreement, on June 4, 2026, all of the Company’s outstanding Convertible Notes were canceled, and the Indenture was satisfied and discharged in full.

ITEM 9A. CONTROLS AND PROCEDURES

Limitations on Effectiveness of Controls and Procedures

In designing and evaluating our disclosure controls and procedures, management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives. In addition, the design of disclosure controls and procedures must reflect the fact that there are resource constraints, and that management is required to apply judgment in evaluating the benefits of possible controls and procedures relative to their costs.

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of our disclosure controls and procedures as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934 (the “Exchange Act”), as of the end of the period covered by this Annual Report. Based on this evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were not effective due to material weaknesses in internal control over financial reporting described below.

Notwithstanding the identified material weaknesses, management, including our Chief Executive Officer and Chief Financial Officer have determined, based on the procedures performed, that the consolidated financial statements included in this Annual Report on Form 10-K fairly represent in all material respects the financial condition, results of operations and cash flows of the Company for the periods presented in accordance with U.S. generally accepted accounting principles.

Management's Annual Report on Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act. Management, with the participation of our Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of our internal control over financial reporting using the framework set forth by the Committee of Sponsoring Organizations of the Treadway Commission in Internal Control—Integrated Framework (2013). Based on this assessment, management concluded that the Company’s internal control over financial reporting was not effective as of March 31, 2026, due to the material weaknesses described below.

A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of the company's annual or interim financial statements will not be prevented or detected on a timely basis.

Management did not adequately design and implement effective control activities resulting in the identification of the following material weaknesses:

Table of Contents

Revenue Recognition

The Company did not maintain effective internal controls related to revenue recognition for the following:

1.Controls for reviewing and updating deferral schedules, which drive the timing of service revenue recognition. Specifically, the start and end dates in the deferral schedules were not consistently aligned with the contractual service periods.

2.Controls over the accuracy of the inputs into the sales order entry process. Specifically, the Company did not execute the controls which cover the review of data inputs in the sales order entry process over a sufficient proportion of the total revenue recognized for the year. These data points include price, quantity, and related customer data.

3.Controls over the allocation of revenue to performance obligations on a standalone selling price basis. Specifically, the Company did not sufficiently document evidence of review of the calculations allocating revenue to performance obligations based on the standalone selling price under Topic 606.

Manufacturing Inventory

The Company did not maintain effective internal controls related to manufacturing inventory. Specifically, controls to reconcile physical inventory with our underlying system records were not adequately executed as of March 31, 2026.

Income taxes

The Company did not maintain effective internal controls over the review of the income tax provision for the year ended March 31, 2026. Management concluded that this deficiency constitutes a material weakness in our internal control over financial reporting. Nonetheless, we have concluded that this material weakness does not require a restatement of or change in our consolidated financial statements for any prior annual or interim period.

Control Environment

Based on the material weaknesses identified, management concluded that the Company did not maintain effective entity-level controls within the control environment to prevent or detect material misstatements to the Consolidated Financial Statements. Specifically, the Company (i) lacked sufficiently qualified staff or resources to perform control activities and (ii) conducted inadequate monitoring activities resulting in untimely or ineffective identification of internal control risks to support the design implementation and evaluation of the internal controls necessary to provide effective oversight over financial reporting. This conclusion is primarily driven by the material weaknesses identified during the year but also by other control weaknesses, which were identified in testing but did not rise to the level of material weaknesses.

While none of the material weaknesses resulted in material misstatements to our Consolidated Financial Statements, each creates a reasonable possibility that a material misstatement could occur and not be prevented or detected on a timely basis.

Remediation Plan

The Company has implemented and is implementing enhancements to address the identified material weaknesses.

Controls for reviewing and updating deferral schedules

Management has designed and is testing a process to automate the start and end date for the deferral schedule to align with the period over which service is delivered to the customer. We anticipate implementing this by the end of our second fiscal quarter.

Controls over the accuracy of the inputs into the sales order entry process.

Management is implementing tools to assist with automating the ingestion of the purchase order from the customer and, therefore, automating the review of data accuracy. We anticipate that manual review would still be required on an exception basis but the automation would allow the Company to increase the population reviewed to 100%. We anticipate implementing this by the end of our second fiscal quarter.

Controls over the allocation of revenue to performance obligations on a standalone selling price basis

In fiscal year 2025, and as noted in Part II, Item 9A of our Annual Report on Form 10-K for the year ended March 31, 2025, the Company implemented a new process for allocation of revenue on a standalone selling price basis,

Table of Contents

but the Company did not sufficiently execute controls over the review of that process. After the start of fiscal year 2026, management implemented a detailed review and documentation process for the allocation of revenue to performance obligations. However, because the detailed review and documentation process did not operate for the full fiscal year, management has concluded that the material weakness remains as of March 31, 2026.

Manufacturing Inventory

Management is implementing two concurrent workstreams to address this control weakness. First, management is working with third-party logistics partners to implement enhanced Electronic Data Interchange ("EDI") processes that will provide timely, automated updates to inventory movement records, directly supporting the accuracy of third-party logistics location reconciliations. Second, management is establishing a formal reconciliation cadence with defined ownership, frequency, and review sign-off requirements. To support consistent execution, management is conducting targeted training on inventory accounting principles with the Inventory Operations Team. These actions are targeted for completion by the end of the third fiscal quarter of fiscal year 2027.

Income taxes

Management is strengthening our income tax control by improving documentation standards, providing enhanced technical oversight and mandatory training for the tax provision reviewer. We anticipate implementing these processes by the end of our second fiscal quarter.

Control Environment

Management is addressing the staffing and monitoring deficiencies underlying this conclusion through targeted hiring to fill key financial reporting roles with appropriately qualified personnel, implementation of a formal monitoring program with defined escalation procedures, and deployment of automation tools to reduce manual control risk. These actions will be evaluated on an ongoing basis as the Company works to remediate the underlying material weaknesses.

The Company is committed to maintaining a strong internal control environment and believes the remediation effort will represent significant improvements in its controls over the control environment. Additional controls may also be required over time. While the Company believes that these efforts will improve its internal control over financial reporting, the Company will not be able to conclude whether the steps the Company is taking will remediate the material weaknesses in internal control over financial reporting until a sufficient period has passed to allow management to test the design and operational effectiveness of the new and enhanced controls. Until the remediation steps set forth above are fully implemented and evaluated, the material weaknesses will continue to exist.

Changes in Internal Controls over Financial Reporting

Except for the matters discussed above, there were no changes in our internal controls over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) identified in connection with the evaluation of our internal control performed during the fiscal quarter ended March 31, 2026, that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

ITEM 9B. OTHER INFORMATION

(b) Trading Plans.

During the fiscal quarter ended March 31, 2026, no director or officer adopted or terminated any contract, instruction, or written plan for the purchase or sale of securities of the Company pursuant to Rule 10b5-1(c) or any non-Rule 10b5-1 trading arrangement (as defined in Item 408(c) of Regulation S-K).
