Deferred tax assets result primarily from net operating loss carryforwards. For federal tax purposes, we have net operating loss carryforwards of approximately $326.4 million of which approximately $192.1 million began expiring in 2025 and will continue to expire through 2040.

In assessing the potential for realization of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will be realized upon the generation of future taxable income during the periods in which those temporary differences become deductible. The Company recognized no income tax expense or benefit for the years ended December 31, 2025 and 2024 as a result of a full valuation allowance against the net deferred tax assets as of December 31, 2025 and 2024. The valuation allowance decreased by $0.1 million during the year ended December 31, 2025. Considered together with the Company's limited history of operating income and its net losses in 2025 and 2024, management has placed a full valuation allowance against the net deferred tax assets as of December 31, 2025 and 2024.
The Company accounts for its uncertain tax positions in accordance with ASC 740‑10, Income Taxes and the amount of unrecognized tax benefits related to tax positions is not significant at December 31, 2025 and 2024. The Company has not been under tax examination in any jurisdiction for the years ended December 31, 2025 and 2024. The Company completed an audit by the Internal Revenue Services for the 2021 tax year resulting in no adjustments. Tax examination years of 2022 through 2024 remain open. A recent IRC Section 382 study has not been performed, which could limit the value of the Company's net operating losses.

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.
