The valuation allowance increased by $6.9 million during the year ended March 31, 2026 and increased by $14.1 million during the year ended March 31, 2025, respectively.

A reconciliation of the gross unrecognized tax benefits is as follows (in thousands):
For the year ended March 31,
2026 2025
Beginning Balance $ 81,678  $ 88,341 
Increase in balances related to tax positions in current period 1,050  1,558 
Increase (decrease) in balances related to tax positions in prior period 40  (12)
Decrease in balances due to lapse in statute of limitations (6,179) (8,209)
Ending balance $ 76,589  $ 81,678 

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
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.
