2025 and Recent Highlights

• We achieved 9% year-over-year revenue growth in our Data Storage business.

Management Commentary

“Despite a nearly $1.9 million decline in our Power Supply business and a slower fourth quarter overall, we delivered net income for the year, driven by growth in our Data Storage business and certain items of non-operating income,” said Steven N. Bronson, President and CEO. “We are confident that we are well-positioned for organic growth in 2026, supported by customer expansion and broader product offerings in data hardware and software solutions. Additionally, we continue to pursue acquisitions related to the data retention industry.”

Consolidated Financial Results (Unaudited)

(Amounts in thousands except per share data and percentages)

Revenue for the quarter decreased 27% to $1.49 million, compared with $2.03 million in the prior-year period, primarily driven by lower sales of power-supply products. For the year ended December 31, 2025, revenue declined 18% compared with the prior year, reflecting reduced shipments of power-supply products, partially offset by higher sales of data-storage products.

Gross margin for the quarter was 20.3%, compared with 33.6% in the prior-year period, reflecting lower revenue and changes in product mix. For the year ended December 31, 2025, gross margin improved to 31.6%, compared with 30.6% in the prior year, primarily driven by a more favorable mix of products and services.

Net income/loss for the three months ended December 31, 2025 and 2024 included gains (losses) on marketable securities of $(35,000) and $(56,000), respectively, and for the years ended December 31, 2025 and 2024 included gains (losses) of $268,000 and $(49,000), respectively.

Adjusted EBITDA for the quarter declined to $(366,000), compared with $91,000 in the prior-year period. For the year ended December 31, 2025, Adjusted EBITDA was $(242,000), compared with $(68,000) for 2024.

Non-GAAP Financial Measure

To supplement our condensed consolidated financial statements, which are prepared and presented in accordance with United States generally accepted accounting principles (“GAAP”), we use the following non-GAAP financial measure: Adjusted EBITDA. The presentation of this financial information is not intended to be considered in isolation or as a substitute for, or superior to, the financial information prepared and presented in accordance with GAAP.

We define Adjusted EBITDA for a particular period as net income (loss) before interest, taxes, depreciation and amortization, and as further adjusted for non-routine expenses that may not be indicative of our core business operating results such as severance compensation, provisions (recoveries) for inventory net realizable value, gains/losses on marketable securities, gains/losses on foreign currency transactions, and non-cash expenses such as stock-based compensation expense.

We use this non-GAAP financial measure for financial and operational decision-making and as a means to evaluate period-to-period comparisons. We believe that this non-GAAP financial measure provides meaningful supplemental information regarding our performance by excluding certain items that may not be indicative of our core business operating results. We believe that both management and investors benefit from referring to this non-GAAP financial measure in assessing our performance and when planning, forecasting, and analyzing future periods. This non-GAAP financial measure also facilitates management’s internal comparisons to our historical performance and liquidity as well as comparisons to our competitors’ operating results. We believe this non-GAAP financial measure is useful to investors both because (1) is allows for greater transparency with respect to key metrics used by management in its financial and operational decision-making and (2) it is used by our investors to help them analyze the health of our business.

There are a number of limitations related to the use of non-GAAP financial measures. We compensate for these limitations by providing specific information regarding the GAAP amounts excluded from these non-GAAP financial measures and evaluating these non-GAAP financial measures together with their relevant financial measures in accordance with GAAP.

The following table reconciles Net Income (Loss) to Adjusted EBITDA for the three months and years ended December 31, 2025 and 2024:
