Note 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Accounts Receivable

Accounts receivable are carried at the original invoice amount less an estimate made for expected credit losses based on a review of all outstanding amounts on a quarterly basis. Management determines the allowance for expected credit losses primarily using historical experience as well as current conditions that affect the collectability of the reported amount. Accounts receivable are written off when deemed uncollectible.  Bad debt expenses are recorded in operating expenses on the consolidated statements of operations.

The activity for the allowance for credit losses during the three months ended March 31, 2026 and 2025 is set forth in the table below:

Inventory Valuation

The Company values inventory at the lower of cost or estimated net realizable value using the first-in first out method. The Company periodically evaluates inventory items not secured by backlog and establishes write-downs to estimated net realizable value for excess quantities, slow-moving goods, obsolescence and for other impairments of value. Adjustments to inventory net realizable value are recorded in cost of sales.

Inventories consist of the following at:

Credit and Concentration Risks

A large percentage of the Company’s revenues are derived directly from large aerospace and defense prime contractors for which the ultimate end-user is the U.S. Government, other governments, or commercial airlines. 

The composition of customers that exceeded 10% of net sales for the three months ended March 31, 2026 and 2025 are shown below:

The composition of customers that exceed 10% of accounts receivable at March 31, 2026 and December 31, 2025 are shown below: 

Disaggregation of Revenue

The following table summarizes revenue from contracts with customers for the three month periods ended March 31, 2026 and 2025:

Cash and Restricted Cash

During the period ended March 31, 2026, the Company had occasionally maintained balances in its bank accounts that were in excess of the FDIC limit. The Company has not experienced any losses on these accounts.

As of March 31, 2026, and December 31, 2025 the Company reported restricted cash of $3,930,000 on its condensed consolidated balance sheets. Restricted cash represents proceeds from the Company’s ATM offering that are pledged as security for its obligations under the Current Credit Facility.

The following table reconciles cash and restricted cash reported in the condensed consolidated balance sheets to the total amount shown in the condensed consolidated statements of cash flows:

Major Suppliers

The Company utilizes sole-source suppliers to supply raw materials or other parts used in production. These suppliers are its only source for such parts and, therefore, in the event any of them were to go out of business or be unable or unwilling to provide parts for any reason, the Company’s business would be severely harmed.

Customer Deposits

The Company receives advance payments on certain contracts with the remainder of the contract balance due upon the shipment of the final product once the customer inspects and approves the product for shipment. At that time, the entire amount will be recognized as revenue and the deposit will be applied to the customer’s invoice.

At March 31, 2026 and December 31, 2025, customer deposits were $968,000 and $391,000, respectively. The Company recognized revenue of $100,000 during the three months ended March 31, 2026 that was included in customer deposits balance as of December 31, 2025. The Company recognized revenue of $531,000 during the three months ended March 31, 2025, that was included in the customer deposits balance as of December 31, 2024.

Backlog

Backlog represents the value of orders received pursuant to our Long-Term Agreements (“LTA”) or spot orders pursuant to a purchase order. As of March 31, 2026, backlog relating to remaining performance obligations on contracts was approximately $134.7 million. The Company estimates that a substantial portion of this backlog will be recognized as net sales during the next twenty-four months, with the rest thereafter. This expectation assumes that raw material supplies and outsourced processing is completed and delivered on time and that the Company’s customers will accept delivery as scheduled. The Company anticipates that sales during the aforementioned periods will also include sales from expected new orders that are not included in our backlog.

Earnings (Loss) per share

Basic earnings (loss) per share (“EPS”) is computed by dividing the net income (loss) applicable to common stockholders by the weighted-average number of shares of common stock outstanding for the period.

For purposes of calculating diluted earnings (loss) per common share, the numerator includes net income (loss) plus interest on convertible notes payable assumed converted as of the first day of the period. The denominator includes both the weighted-average number of shares of common stock outstanding during the period and the number of common stock equivalents if the inclusion of such common stock equivalents is dilutive. Dilutive common stock equivalents potentially include stock options and warrants using the treasury stock method and convertible notes payable using the if-converted method.

The following securities have been excluded from the calculation because the effect of including these potential shares was anti-dilutive due to the net loss incurred during that period:

Stock-Based Compensation

The Company accounts for stock-based compensation in accordance with FASB ASC 718, “Compensation – Stock Compensation.” Under the fair value recognition provision of the ASC, stock-based compensation cost is estimated at the grant date based on the fair value of the award. The Company estimates the fair value of stock options and warrants granted using the Black-Scholes-Merton option pricing model and stock grants at their closing reported market value. Stock-based compensation expense for employees amounted to $535,000 and $435,000 for the three months ended March 31, 2026 and 2025, respectively. Stock-based compensation expense for directors amounted to $429,000 and $39,000 for the three months ended March 31, 2026 and 2025, respectively. Stock compensation expenses for employees and directors were included in operating expenses in the accompanying condensed consolidated statements of operations.

Recently Issued Accounting Pronouncements

In November 2024, the FASB issued ASU 2024-03, “Disaggregation of Income Statement Expenses”, which requires public business entities to disclose additional information about specific expenses categories in the notes to financial statements at interim and annual reporting periods. The amendments in ASU 2024-03 are effective for annual reporting periods beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027. Early adoption is permitted. The Company is currently assessing the impact that adoption of this new accounting guidance will have on its consolidated financial statements and footnote disclosures.

The Company does not believe that any other recently issued, but not yet effective, accounting standards if currently adopted would have a material effect on the accompanying condensed consolidated financial statements.
