Income Tax Disclosure [Text Block]	13. Income Taxes The Company recorded income tax benefits of $112.4 million and $112.1 million for the three and nine months ended December 31, 2025, respectively, and income tax benefit of $0.1 million and $4.9 million for the three and nine months ended December 31, 2024, respectively. On a quarterly basis, the Company reassesses the valuation allowance on deferred income tax assets, weighing positive and negative evidence to assess the recoverability of the deferred tax assets. As of December 31, 2025, the Company recorded a $113.1 million non-cash income tax benefit related to the release of a substantial portion of its valuation allowance against deferred tax assets. This was based on the Company's evaluation of the positive evidence, including cumulative income position over the three-year period December 31, 2025, revenue growth, current profitability, expectations regarding future forecasted income, and negative evidence, including uncertainty in economic and political environments from industry competition and dependence on government contracts. This release of the valuation allowance resulted in the recognition of a deferred tax asset and a corresponding increase to income tax benefit in the current period, the effect of which is an increase in reported net income. On July 4, 2025, the reconciliation bill, commonly referred to as the One Big Beautiful Bill ("OBBB") was signed into law, which includes a broad range of tax reform provisions that may affect the company's financial results. The OBBB allows an elective deduction for domestic Research and Development (R&D), a reinstatement of elective 100% first-year bonus depreciation, and a more favorable tax rate on Foreign-derived Deduction Eligible Income and income from non-U.S. subsidiaries (Net CFC Tested Income), among other provisions. The Company has performed an initial evaluation of the impact of the OBBB on the Company's effective tax rate and deferred tax assets in 2025 and future periods. Based on this initial evaluation, the Company believes the tax reform provisions will not have a material impact on the Company’s consolidated financial statements and related disclosures. We will continue to assess the implications of the OBBB, and our tax provision may be further impacted as additional guidance from the U.S. Department of the Treasury is released. Accounting for income taxes requires a two-step approach to recognizing and measuring uncertain tax positions. The first step is to evaluate the tax position for recognition by determining if, based on the technical merits, it is more likely than not the position will be sustained upon audit, including resolution of related appeals or litigation processes, if any. The second step is to measure the tax benefit as the largest amount that is more than 50% likely to be realized upon ultimate settlement. The Company re-evaluates these uncertain tax positions on a quarterly basis. The evaluation is based on factors including, but not limited to, changes in facts or circumstances, changes in tax law, effectively settled issues under audit and new audit activity. Any changes in these factors could result in the recognition of a tax benefit or an additional charge to the tax provision. The Company did not identify any uncertain tax positions in the nine months ended December 31, 2025 and did not have any gross unrecognized tax benefits as of December 31, 2025.
