As of December 31, 2025, the Company had approximately $2,128.2 million of federal net operating loss (“NOL”) carryforwards, $1,155.2 million of state NOL carryforwards, and $99.2 million of foreign NOL carryforwards. The federal NOL carryforwards of $2,128.2 million generated after December 31, 2017 will carry forward indefinitely. A portion of the state and foreign NOL carryforwards will begin to expire in 2026. As of December 31, 2025, the Company had no foreign tax credits. As of December 31, 2025, the Company had $29.3 million federal and state research and development credits.

As of December 31, 2025, the Company had a valuation allowance of approximately $453.4 million against a portion of the U.S. and certain foreign deferred tax assets, for which realization cannot be considered more likely than not at this time. The valuation allowance increased by $36.7 million from December 31, 2024 due to a reduction of sources of future taxable income related to decreasing deferred tax liabilities.

The Company files tax returns as prescribed by the tax laws of the jurisdictions in which it operates. In the normal course of business, the Company is subject to examination by federal and state jurisdictions in the U.S. and other countries, where applicable. The Company is open under the U.S. federal statute from 2021 to the present, although earlier years may be examined to the extent that loss carryforwards are used in open audit periods. The Company is currently not under audit by the IRS or in any foreign tax jurisdictions. One state is currently under audit in the United States. There are no tax matters under discussion with taxing authorities that are expected to have a material effect on the Company's consolidated financial statements. The Company further believes that it has made adequate provision for all income tax uncertainties.

On July 4, 2025, the One Big Beautiful Bill Act (“OBBBA”) was signed into law, introducing significant federal tax changes, including the restoration of immediate expensing for domestic research and experimental (“R&E”) expenditures under new Section 174A beginning with tax years starting January 1, 2025. This change eliminates the prior requirement to amortize domestic R&E costs over five years for post‑2021 expenditures and allows companies to deduct qualifying U.S.‑based R&D expenses in the year incurred. The Company has evaluated the impacts of OBBBA, including the reinstated immediate deduction for domestic R&D activities and related implementation considerations. Based on the Company’s current operations, projected R&D spending profile, and the transitional mechanics affecting 2022–2024 R&D
balances described in the legislation, the Company does not expect these provisions to have a material impact on its consolidated financial statements. The Company will continue to monitor future guidance and any state-level conformity developments, but no material effects are anticipated at this time.

During 2021, the Organization for Economic Co-operation and Development announced an agreed framework for “Pillar Two” and released detailed model rules for a global minimum corporate tax rate of fifteen percent (15%) which requires multilateral agreement(s) and/or country-specific legislative action to be effective. A few jurisdictions have implemented legislation with effective dates spanning from 2024 through 2026. The Company will continue to monitor further legislation by individual countries and is currently evaluating the potential impact of Pillar Two to its business in future periods. However, the Company is not likely to have any material Pillar Two liability.

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.
