Quantum Corporation Reports Fiscal Second Quarter 2018 Results

Also Announces:


•	CEO Transition - Adalio T. Sanchez Appointed Interim CEO, Replacing Jon Gacek


•	Financing - Secured Additional $20 Million in Capital; On Track to Pay Off Convertible Notes on Nov. 15


•	Executing Annualized Cost Savings of $15 Million in Fiscal 2018 and Up to $35 Million by End of Fiscal 2019


•	Appointment of Eric Singer from VIEX Capital Advisors to Board of Directors


•	Expected Strong Sequential Revenue and Profitability Growth in Second Half of Fiscal 2018

SAN JOSE, Calif. - Nov. 9, 2017 - Quantum Corp. (NYSE: QTM) today reported results for the fiscal second quarter 2018 ended Sept. 30, 2017, and made a number of other announcements.

Fiscal Second Quarter Results

For the fiscal second quarter 2018, Quantum reported the following (all comparisons are relative to the fiscal second quarter 2017 unless otherwise stated):


•	Total revenue of $107.1 million, down from $134.7 million in the prior year period which included approximately $15 million in revenue from a large public cloud deal. The year-over-year decline was greater than expected largely due to timing of closing deals at quarter end, third-party component supply shortages and softness in disk backup systems sales.


•	Scale-out tiered storage revenue¹ of $33.8 million, a decline of $12.9 million, largely attributable to the public cloud deal a year earlier.





¹ All revenue figures for scale-out tiered storage, data protection, disk backup systems and tape automation, devices and media in this press release include related service revenue.


•	Total data protection revenue of $63.9 million, down from $78.4 million and consisting of:


•	$52.2 million in tape automation, devices and media revenue, compared to $59.7 million, with OEM revenue declining 24 percent and branded revenue declining 14 percent.


•	$11.7 million in disk backup systems revenue, down from $18.7 million in the comparable quarter which included several deals exceeding $1 million.


•	Royalty revenue of $9.3 million, a decline of $300,000.


•	GAAP net loss of $7.9 million, or $0.23 per diluted share, compared to net income of $4.1 million.


•	Non-GAAP net loss of $4.9 million, or $0.14 per diluted share, compared to net income of $6.4 million.

“We’re disappointed that our results fell short of our expectations, but we’re taking aggressive action to improve our cost structure and generate consistent growth and profitability,” said Fuad Ahmad, senior vice president and CFO of Quantum. “We believe part of the challenge at quarter end involved timing of deals, and we’ve already shipped more than 50 percent of the revenue from deals that weren’t closed, including those delayed by third-party component supply shortages.

“Despite the difficulties we encountered in the quarter, there were some bright spots, including strong year-over-year growth in video surveillance, positive customer reception to our new StorNext 6-powered solutions and the increased market opportunities resulting from new partnerships.”

CEO Transition

Quantum has named board member Adalio T. Sanchez interim CEO to replace Jon Gacek, who has left the company. Sanchez is a 35-year IT industry veteran who spent most of his career at IBM, including 16 years in senior executive and global general management roles. The board also has formed a search committee which will be headed by Chairman Raghu Rau and has retained Korn Ferry International to commence a search for a permanent CEO.

“Adalio brings tremendous domain expertise in systems and storage, along with a proven track record of transforming businesses,” said Rau. “Since joining the board in May, Adalio has been leading our engagement with AlixPartners and will hit the ground running to drive improved execution at the company.”

Convertible Notes Repayment and Additional Financing

Quantum announced that it has secured a $20 million incremental delayed draw term loan financing facility from TCW Direct Lending. The new capital is being provided under amended credit agreements with TCW and PNC Bank and is on top of the $170 million financing package with the two lenders that

the company announced in October of last year. This brings the total cash secured under delayed draw term loans to $40 million, including $20 million in previously committed funds. In addition to the incremental financing, the amended agreements include less restrictive covenants than the original agreements.

“We appreciate the continued support from our lenders,” said Ahmad. “The additional financing will give us more financial and operational flexibility to execute and puts us on track to pay off the remaining $57 million of the company’s convertible notes upon maturity next Wednesday, Nov. 15.”

Executing on Strategic Review to Transform Quantum’s Business

In June, Quantum’s newly reconstituted board of directors initiated a comprehensive strategic review of the company’s business and engaged AlixPartners to assist in identifying cost savings to increase profitability, financial flexibility and growth investments. The cost reduction measures will result in $5 million of savings in the second half of this fiscal year (or $15 million on an annualized basis) and up to $35 million in annualized savings by the end of fiscal 2019.

Appointment of Eric Singer to Quantum Board

Quantum has appointed Eric Singer, founder and managing member of VIEX Capital Advisors and the company’s largest shareholder, to the board. Singer will bring a shareholder perspective to the board and will assist in creating increased value for all shareholders.

Fiscal Second Quarter Business Highlights

•

Quantum announced general availability of StorNext 6, a major new release of the company’s award-winning StorNext^® scale-out file system. It delivers a unique combination of new advanced data management features for on-premise, hybrid cloud and public cloud environments and industry-leading streaming performance. Now shipping with the company’s Xcellis workflow storage solutions, StorNext 6 enables users to overcome the limitations of traditional NAS systems in keeping up with the demands of large, rapidly growing data-intensive workloads and driving business value from that data.

•

The company introduced Xcellis Foundation, a high-performance, entry-level workflow storage system specifically designed to address the technical and budgetary requirements of small-to medium-sized postproduction facilities and corporate video departments. The new system delivers the benefits of enterprise-class Xcellis storage, including high performance and scalability, in a NAS appliance for under $25,000.

•

Quantum unveiled aiWARE™ for Xcellis, an on-premise and cloud version of the artificial intelligence (AI) platform from Veritone. By bringing Veritone’s multi-engine AI capabilities into a StorNext-managed environment, aiWARE for Xcellis enables users to leverage the power of Veritone’s cognitive services and applications to extract new value from their on-premise video and audio content. The integrated solution is ideal for companies with significant investments in on-premise storage and/or latency, cost or security concerns about cloud storage because it puts powerful AI processing behind corporate firewalls.

•

Announced in late August, aiWARE for Xcellis quickly garnered a NewBay Best of Show Award at the IBC2017 show in September. Award criteria included innovation, feature set, ease of use, versatility and ROI. In addition, at the end of September, Quantum secured its first customer win for the new solution. FOX Sports Brazil, an existing StorNext customer, is deploying aiWARE for Xcellis to enrich and index both archived content and live video streams through cognitive analytics.

Use of Non-GAAP Financial Measures

Quantum believes that the non-GAAP financial measures disclosed above provide useful and supplemental information to investors regarding its quarterly financial performance. Quantum management and Board of Directors use these non-GAAP financial measures internally to understand, manage and evaluate the company’s business results and make operating decisions. For instance, Quantum management often makes decisions regarding staffing, future management priorities and how the company will direct future operating expenses on the basis of non-GAAP financial measures. In addition, compensation of our employees is based in part on the performance of our business based on non-GAAP operating income.

Amortization of Intangible Assets

This includes acquired intangibles such as purchased technology in connection with prior acquisitions which are included within other long-term assets in the Condensed Consolidated Balance Sheet. These expenses are not factored into management’s evaluation of potential acquisitions or Quantum’s performance after completion of the acquisitions because they are not related to Quantum’s core operating performance. In addition, the frequency and amount of such charges can vary significantly based on the size and timing of acquisitions and the maturities of the businesses being acquired. Excluding acquisition-related charges from non-GAAP measures provides investors with a basis to compare Quantum against the performance of other companies without the variability caused by purchase accounting.

Share-Based Compensation Expense

Share-based compensation expense relates primarily to equity awards such as stock options, restricted stock units and employee stock purchase plan. Share-based compensation is a non-cash expense that varies in amount from period to period and is dependent on market forces that are often beyond Quantum’s control. Management believes that non-GAAP measures adjusted for share-based compensation provide investors with a basis to measure Quantum’s core performance against the performance of other companies without the variability

created by share-based compensation as a result of the variety of equity awards used by other companies and the varying methodologies and assumptions used.

Amortization of Debt Costs

Amortization of debt costs, included in interest expense, relates to the amortization of fees incurred and paid in connection with the issuance of our debt and convertible notes. Amortization of debt costs is a non-cash expense that is representative of a single transaction which occurred in prior periods. The amount is excluded from non-GAAP financial measures because it is not considered a core operating activity. Management believes that it is appropriate to exclude the amortization from interest expense in order to provide investors the ability to compare Quantum’s period-over-period results from continuing operations.

Restructuring Charges

Restructuring charges primarily relate to expenses associated with changes to Quantum’s operating structure. Restructuring charges are excluded from non-GAAP financial measures because they are not considered core operating activities. Although Quantum has engaged in various restructuring activities in the past, each has been a discrete event based on a unique set of business objectives. Management believes that it is appropriate to exclude restructuring charges from Quantum’s non-GAAP financial measures, as it enhances the ability of investors to compare Quantum’s period-over-period operating results from continuing operations.

Proxy Contest and Related Costs

Proxy contest and related costs are expenses incurred to respond to activities and inquiries of VIEX Capital Advisors, LLC, including their proxy solicitation and subsequent costs related to the identification and appointment of new board members. These costs are not considered core operating activities. Management believes that it is appropriate to exclude these costs in order to provide investors the ability to compare Quantum’s period-over-period operating results from continuing operations.

Litigation Costs

Litigation costs are expenses incurred to defend ourselves and perform other activities related to certain patent infringement lawsuits filed by third parties. These costs are excluded from non-GAAP financial measures because they are not considered core operating activities. Management believes that it is appropriate to exclude these costs in order to provide investors the ability to compare Quantum’s period-over-period operating results from continuing operations.

Business Transition Costs

Business transition costs were expenses incurred from a third party consulting firm to identify opportunities for reducing costs, achieving greater operational efficiencies and reinvesting to accelerate growth. These costs are excluded from non-GAAP financial measures because they are not considered core operating activities. Management believes that it is appropriate to exclude these costs in order to provide investors the ability to compare Quantum’s period-over-period operating results from continuing operations.

Non-GAAP financial measures should not be considered as a substitute for, or superior to, measures of financial performance prepared in accordance with GAAP. They are limited in value because they exclude charges that have a material impact on the company’s reported financial results and, therefore, should not be relied upon as the sole financial measures to evaluate the company. The non-GAAP financial measures are meant to supplement, and be viewed in conjunction with, GAAP financial measures. Investors are encouraged to review the reconciliation of the non-GAAP financial measures to their most directly comparable GAAP financial measures as provided in the tables accompanying this press release.
