(1)Change in valuation allowance includes the Mesa valuation allowance as of the Merger closing date, which does not impact provision for income tax expense.
The Company’s deferred tax assets were generated as a result of temporary differences between deductibility of reserves, accruals, and operating lease liabilities and recognition of revenue for the determination of income on a tax basis versus a U.S. GAAP basis combined with significant NOLs. Deferred tax liabilities relate predominantly to differences in U.S. GAAP and tax basis of aircraft and equipment and the related right of use assets created as the present value of remaining lease payments at the measurement date. The Company accelerates depreciation for tax reporting purposes for new aircraft and equipment deliveries.
The Company monitors ongoing tax cases related to its unrecognized tax benefits. The unrecognized tax benefits, which if recognized, would impact the effective tax rate. As of December 31, 2025 the Company has reversed all liabilities related to unrecognized tax benefits due to the expiration of the statute of limitations.

As of December 31, 2025, the Company has Federal NOL carryforwards totaling approximately $300 million, of which a portion begin expiring during 2036. Approximately $190 million of our Federal NOL carryforwards are not subject to expiration. These NOL carryovers are only available to offset 80% of taxable income in years in which they are utilized due to tax law changes as a result of the Tax Cuts and Jobs Act. The Company also has $70 million of interest expense carryovers as a result of 163(j) limitations as of December 31, 2025, which do not expire. Tax years beginning in 2007 through 2025 are currently subject to examination by the Internal Revenue Service.
The Company cannot conclude that it is more likely than not that the benefit from certain Federal and state NOL carryforwards will be realized. In recognition of this uncertainty, the Company has provided a valuation allowance of $82.7 million and $36.4 million as of December 31, 2025 and 2024, respectively, on the deferred tax assets related to these NOL carryforwards. If or when recognized, the tax benefits related to any reversal of the valuation allowance on deferred tax assets will be recognized as a reduction of income tax expense.

About Income Taxes Disclosures

The income tax disclosure reveals how much a company actually pays in taxes versus what the statutory rate would predict. Analysts focus on the effective tax rate (ETR) reconciliation, which breaks down every item driving the gap between the 21% federal rate and the company's reported ETR — including R&D credits, foreign rate differentials, and state taxes. Deferred tax assets (DTAs) and their valuation allowances signal management's confidence in future profitability: a rising allowance suggests the company doubts it can use accumulated tax benefits. Uncertain tax benefit (UTB) reserves quantify exposure to IRS challenges on aggressive positions.

Key signals to watch: sudden ETR drops without clear operational reasons, large increases in valuation allowances, growing UTB balances, and significant unremitted foreign earnings. Post-TCJA, pay attention to GILTI and BEAT provisions that affect multinational tax structures. Compare the cash taxes paid (from the cash flow statement) against the income tax provision to gauge earnings quality.
