At December 31, 2025, United had:

$35.4 million of state net operating loss carryforwards subject to annual limitation under Internal Revenue Code Section 382 that begin to expire in 2026, if not previously utilized.

$27.5 million of state net operating loss carryforwards that begin to expire in 2026, if not previously utilized.

$41.7 million in federal net operating loss carryforwards subject to annual limitation under IRC Section 382 that begin to expire in 2027, if not previously utilized.

$5.50 million of state tax credits that begin to expire in 2027, if not previously utilized.
 
Management assesses the valuation allowance recorded against DTAs at each reporting period. The determination of whether a valuation allowance for DTAs is appropriate is subject to considerable judgment and requires an evaluation of all the positive and negative evidence. ASC 740 requires that companies assess whether a valuation allowance should be established against their DTAs based on the consideration of all available evidence using a “more likely than not” standard.
 
At December 31, 2025 and 2024, based on the assessment of all the positive and negative evidence, management concluded that it is more likely than not that nearly all of the net DTA will be realized based upon future taxable income. The valuation allowance of $1.09 million and $1.17 million, respectively, was related to acquired state net operating losses, which are subject to limitations and are therefore expected to expire unused.
The valuation allowance could fluctuate in future periods based on the assessment of the positive and negative evidence. Management’s conclusion at December 31, 2025 that it was more likely than not that the net DTA of $75.9 million will be realized is based on management’s estimate of future taxable income. Management’s estimate of future taxable income is based on internal forecasts which consider historical performance, various internal estimates and assumptions, as well as certain external data all of which management believes to be reasonable although inherently subject to significant judgment. If actual results differ significantly from the current estimates of future taxable income, even if caused by adverse macro-economic conditions, the valuation allowance may need to be increased for some or all of the net DTA.

A reconciliation of the beginning and ending unrecognized tax benefit related to uncertain tax positions is as follows for the years indicated:
(in thousands)
202520242023
Balance at beginning of year$3,535 $2,956 $2,848 
Additions based on tax positions related to the current year1,272 999 939 
Decreases resulting from a lapse in the applicable statute of limitations(582)(420)(831)
Balance at end of year$4,225 $3,535 $2,956 
 
Approximately $3.34 million of the unrecognized tax benefit at December 31, 2025 would increase income from continuing operations, and thus affect United’s effective tax rate, if ultimately recognized into income.
 
United recognizes interest and penalties relative to unrecognized tax benefits in income tax expense. No amounts related to unrecognized tax benefits were accrued or expensed at December 31, 2025 or 2024.

United and its subsidiaries file a consolidated U.S. federal income tax return, as well as various state returns in the states where it operates. United’s federal and state income tax returns are generally no longer subject to examination by taxing authorities for years before 2022.

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.
