Inflection Point: OSS Lifts 2025 Revenue Guidance After Delivering Higher Gross Margin and Positive EBITDA
One Stop Systems (OSS) reported a significant turnaround in Q3 2025, marked by a 37% year-over-year revenue increase to $18.8 million, sharp improvement in profitability metrics, and higher margins across its business segments. Buoyed by demand from defense and industrial markets, the company also raised its full-year revenue guidance to $63–$65 million, up from a previous $59–$61 million range.
Consolidated Growth Backed by Segment Strength—Defense Drives OSS Segment Surge
The company's OSS segment revenue grew 43.4% to $9.26 million, fueled by new and expanded programs in defense, as well as growth from autonomous and medical device applications. Bressner, its European-focused unit, saw revenue increase 31.1% year-over-year, primarily on the back of heightened industrial demand.
| Segment | Q3 2025 Revenue ($) | Q3 2025 % of Net Revenue | Q3 2024 Revenue ($) | Q3 2024 % of Net Revenue | % Change |
|---|---|---|---|---|---|
| OSS | 9,262,517 | 49.4 | 6,460,290 | 47.2 | 43.4 |
| Bressner | 9,493,682 | 50.6 | 7,240,807 | 52.8 | 31.1 |
| Total | 18,756,199 | 100.0 | 13,701,097 | 100.0 | 36.9 |
Margin Expansion and Return to Profitability Stand Out
OSS's consolidated gross margin climbed to 35.7%, compared to -12.5% in the prior-year quarter (impacted by a large inventory charge) and even surpassed the adjusted 32% margin from last year. OSS segment margin reached an impressive 45.6%. As a result, net income swung to $0.3 million ($0.01 per share) from a net loss of $6.8 million, and adjusted EBITDA was positive $1.2 million, versus a $6 million loss a year ago.

Financial Flexibility Enhanced with New Capital
OSS took further steps to strengthen its financial position by raising $12.5 million in a direct offering after the quarter ended. This gives the company additional flexibility to support ongoing operations and strategic growth initiatives, especially as it builds out its pipeline in both commercial and defense markets.
Guidance Lift Reflects Confidence in Commercial and Defense Momentum
Management now anticipates consolidated 2025 revenue of $63–$65 million (previously $59–$61 million), with the OSS segment expected to contribute $30–$32 million. The company also reaffirmed its expectation to remain EBITDA positive for the full year.
| Metric | 2025E Guidance | Previous Guidance |
