At December 31, 2025, the Company has unused U.S. federal and state net operating loss (“NOL”) carryforwards of $54.7 million that may be applied against future taxable income. The state NOL carryforwards begin to expire in 2030. The U.S. federal NOL carryforwards may be carried forward indefinitely, however are limited to 80 percent of taxable income. The Company has unused Australian NOL carryforwards of $0.3 million that may be carried forward indefinitely. The Company has unused U.S. federal research and development (“R & D”) tax credits of $.07 million that begin to expire in 2041.
The use of the Company’s NOL and R & D credit carryforwards may, however, be subject to limitations as a result of an ownership change. A corporation undergoes an “ownership change,” in general, if a greater than 50% change (by value) in its equity ownership by one or more five-percent stockholders (or certain groups of non-five-percent stockholders) over a three year period occurs. After such an ownership change, the corporation’s use of its pre-change NOL carryforwards and other pre-change tax attributes to offset its post-change income is subject to an annual limitation determined by the equity value of the corporation on the date the ownership change occurs multiplied by a rate determined monthly by the Internal Revenue Service.
If an ownership change occurs and if the Company earns net taxable income, the Company’s ability to use its pre-change NOLs to offset U.S. federal and taxable income would be subject to these limitations, which could potentially result in increased future tax liability compared to the tax liability the Company would incur if its use of NOL carryforwards were not so limited. In addition, for state income, franchise and similar tax purposes, there may be periods during which the use of NOL carryforwards is suspended or otherwise limited, which could accelerate or permanently increase the Company’s state income, franchise, or similar taxes.
In accordance with ASC 740, “Income Taxes,” the Company recorded a valuation allowance to fully offset its deferred tax assets, because it is not more likely than not that the Company will realize future benefits associated with these deferred tax assets at December 31, 2025 and 2024.The valuation allowance increased by approximately $7.7 million during the year ended December 31, 2025, related to U.S. federal, state, and foreign jurisdictions in the amounts of $4.8 million, $2.8 million, and $0.1 million, respectively. The valuation allowance increased by approximately $4.8 million during the year ended December 31, 2024, related to the U.S. federal, state and foreign jurisdictions in the amount of $3.3 million, $1.5 million and zero, respectively Increases to the valuation allowance were mainly due to increases in the NOL carryforward and other deferred tax assets. The Company will continue to assess the realizability of the deferred tax assets at each interim and annual balance sheet date based upon actual and forecasted operating results.

The Company accounts for uncertain tax positions in accordance with the provisions of ASC 740. When uncertain tax positions exist, the Company recognizes the tax benefit of tax positions to the extent that the benefit would more likely than not be realized assuming examination by the taxing authority. The determination as to whether the tax benefit will more likely than not be realized is based upon the technical merits of the tax position as well as consideration of the available facts and circumstances. The Company recognizes any interest and penalties accrued related to unrecognized tax benefits as income tax expense. The Company did not have any significant unrecognized tax benefits during the years ended December 31, 2025 and 2024. The Company files income tax returns in the U.S. federal jurisdiction, several U.S. States, Australia, and Romania. The Company’s tax returns since inception remain open to examination by the taxing authorities.

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.
