The Company evaluated subsequent events and transactions that occurred after the balance sheet date through May 7, 2026, the date that these consolidated financial statements were available to be issued. Based upon this review, the Company did not identify any subsequent events that would have required adjustment or disclosure in the consolidated financial statements other than the events described below.

Promissory Note

In April 2026, the Company purchased a piece of property which provides direct rail access adjacent to its PFNWR facility pursuant to a Purchase and Sales Agreement dated November 17, 2025, for a purchase price of $350,000. The Company paid $87,500 in cash and entered into a promissory note dated April 15, 2026, in an amount of $262,500 with a bank (the “lender”) for the remaining balance of the purchase price, with a maturity date in ten years or April 15, 2036 (the “Note”). For the first five years starting May 15, 2026, monthly payments under the Note will consist of approximately $3,100 which include an annual fixed interest rate of 7.50%. Monthly payments under the Note will then be adjusted at the end of year five, with interest calculated based on the weekly average five-year US Treasury Securities Rate plus 3.0%. Under no circumstances will the variable interest rates on the Note be less than 4.0% per annum or more than (except in the case of default) the lesser of 20.5% per annum or the maximum rate allowed by applicable law. The Company agreed to pay the lender 3.0% of the total outstanding principal balance under the Note if the Company pays off its obligations during the first year of the Note. The prepayment penalty rate will be reduced by 1.0% at each subsequent annual anniversary of the Note. No prepayment penalty will apply in the event the Company pays off the Note on the fourth anniversary of the Note or thereafter.

NOV

On April 30, 2026, the Company received an NOV from the Washington State Department of Ecology (the “Department of Ecology”) following a June 24, 2025 inspection of the Company’s PFNWR facility in Richland, Washington. The NOV is based on an inspection report identifying alleged non-compliance with certain Department of Ecology waste regulations and permit requirements and requires the Company to implement specified corrective actions and provide documentation of its compliance within prescribed timeframes.

No administrative order has been issued and no monetary penalties have been assessed as of the date of this report. The Company is actively responding to the NOV and implementing corrective measures. Based on information currently available and the Company’s ongoing response, the Company does not expect this matter to result in a material adverse effect on its financial condition, results of operations, or cash flows.

The outcome of this matter remains subject to regulatory review. While the Department of Ecology may pursue escalated enforcement action in accordance with Washington State Dangerous (Hazardous) Waste Regulations, the Company currently expects a favorable resolution of the NOV and is not able to reasonably estimate the amount or range of any potential loss, if any, associated with this matter.
