NOTE 13 — INCOME TAXES

For fiscal year ended March 31, 2026, Orion’s deferred tax assets were primarily the result of U.S. net operating loss ("NOL") and tax credit carryforwards. Orion recorded a valuation allowance of $28.6 million and $28.1 million against its net deferred tax asset balance as of March 31, 2026 and March 31, 2025, respectively, due to the uncertainty of its realization value in the future. For fiscal

years ended March 31, 2026 and March 31, 2025, the valuation allowance against Orion’s deferred tax assets increased by $0.5 million, primarily due to the current and prior year book losses.

As of each reporting date, management considers new evidence, both positive and negative, that could affect its view of the future realization of deferred tax assets. Orion considers future taxable income and ongoing prudent and feasible tax planning strategies in assessing the need for the valuation allowance. In the event that Orion determines that the more or less of its deferred tax assets are able to be realized, an adjustment to the valuation allowance would be reflected in the company’s provision for income taxes.

As of March 31, 2026, Orion has federal NOL carryforwards of approximately $87.2 million, state NOL carryforwards of approximately $73.4 million, and foreign NOL carryforwards of approximately $0.6 million. Orion also had federal tax credit carryforwards of approximately $1.1 million and state tax credits of $0.1 million. All of Orion’s tax credit carryforwards and $123.4 million of its NOL carryforwards will begin to expire in varying amounts between 2026 and 2056. The remaining $37.8 million of its federal and state NOL carryforwards are not subject to time restrictions but may only be used to offset 80% of adjusted taxable income. Orion believes it is more likely than not that the benefit from its state credit carryforwards, foreign NOL carryforwards, federal credit carryforwards, and state loss carryforwards will not be realized. In recognition of this risk, Orion has provided a net valuation allowance of $28.6 million on the deferred tax assets related to these carryforwards.

Generally, a change of more than 50% in the ownership of Orion's stock, by value, over a three-year period constitutes an ownership change for federal income tax purposes as defined under Section 382 of the Internal Revenue Code. As a result, Orion's ability to use its net operating loss carryforwards, attributable to the period prior to such ownership change, to offset taxable income can be subject to limitations in a particular year, which could potentially result in increased future tax liability for Orion. There was no limitation of NOL carryforwards that occurred for fiscal 2026, fiscal 2025, or fiscal 2024.

Orion records its tax provision based on the respective tax rules and regulations for the jurisdictions in which it operates. Where Orion believes that a tax position is supportable for income tax purposes, the item is included in their income tax returns. Where treatment of a position is uncertain, a liability is recorded based upon the expected most likely outcome taking into consideration the technical merits of the position based on specific tax regulations and facts of each matter. These liabilities may be affected by changing interpretations of laws, rulings by tax authorities, or the expiration of the statute of limitations.

Orion files income tax returns in the United States federal jurisdiction and in several state jurisdictions. The Company's federal tax returns for tax years beginning April 1, 2021 or later are open. For states in which Orion files state income tax returns, the statute of limitations is generally open for tax years beginning April 1, 2021 or later.

State income tax returns are generally subject to examination for a period of 3 to 5 years after filing of the respective return. The state effect of any federal changes remains subject to examination by various states for a period of up to two years after formal notification to the states. Orion currently has no state income tax return positions in the process of examination, administrative appeals or litigation.

Uncertain tax positions

As of March 31, 2026, the balance of gross unrecognized tax benefits was approximately $0.3 million, all of which would affect Orion’s effective tax rate if recognized.

Orion has classified the amounts recorded for uncertain tax benefits in the balance sheet as other liabilities (non-current) to the extent that payment is not anticipated within one year. Accrued interest and penalties for such unrecognized tax benefits as of March 31, 2026 and 2025 were $0.1 million. Orion had the following unrecognized tax benefit activity (dollars in thousands):
