OSS Sees Book-to-Bill of 1.8x, Gross Margins at Multi-Year Highs: Breaking Down the Q1 2026 Financials
Strong Demand Signals: Bookings Drive a 1.8x Book-to-Bill and Expanding Pipeline
One Stop Systems (NASDAQ: OSS) kicked off 2026 with momentum, delivering a book-to-bill ratio of 1.8x, among the strongest in its history. Q1 bookings nearly reached $15 million. This spike in orders, paired with continued backlog expansion, signals an underlying demand for OSS’s rugged, enterprise-class compute platforms in both defense and commercial verticals. The company’s trailing twelve-month book-to-bill also stayed above 1.2x—a threshold indicating more new orders than fulfilled shipments, setting the stage for sustained revenue growth.
Profitability Improvement: Gross Margin Expands by 610 Basis Points
OSS posted Q1 2026 revenues of $8.1 million, up 55% from the prior year. Gross margin surged to 51.6%, a 610-basis point year-over-year improvement, driven by a richer product mix, higher engineering efficiencies, and increased manufacturing scale. Despite operating expenses ticking up by just 2.5%, the company successfully shrank its net loss from continuing operations to $0.4 million. Notably, on a non-GAAP basis, OSS turned a profit, reporting net income of $0.3 million and improved adjusted EBITDA.
| Metric | Q1 2026 | Q1 2025 |
|---|---|---|
| Revenue | $8.10M | $5.21M |
| Gross Margin | 51.6% | 45.5% |
| Book-to-Bill | 1.8x | N/A |
| Net Cash Provided by Operating Activities | $4.00M | ($1.50M) |
| Non-GAAP Net Income (Loss) from Continuing Ops | $0.30M | ($1.70M) |
| Adjusted EBITDA | $0.18M | ($1.58M) |
Cash Generation and a Solid Balance Sheet Strengthen Foundation
OSS generated a record $4 million in net cash from continuing operating activities in Q1, a substantial improvement from the prior year’s outflow. The balance sheet remains strong with $34.4 million in cash, cash equivalents, and short-term investments, complemented by $44.7 million in working capital. This healthy liquidity gives OSS flexibility to pursue organic growth and consider inorganic opportunities if attractive deals arise.
Momentum in Core Markets: Defense and Commercial Sales Fuel Growth
The revenue surge was anchored by significant orders from defense and medical imaging customers, including large contracts for the P-8A program and an advanced vision system for combat vehicles. Incrementally, sales to a medical imaging OEM supplied further top-line growth, demonstrating OSS’s ability to address both rugged defense projects and specialty commercial needs.
Outlook Remains Upbeat with Focus on Recurring Revenue and Backlog
For the full year 2026, OSS is targeting 20% to 25% revenue growth, gross margins around 40%, and continued positive EBITDA metrics. Management highlights a strategic shift toward integrating solutions that can drive recurring, predictable revenue streams and stacking a robust, multi-year backlog. The company is mindful of external variables, such as supply chain volatility and federal budget uncertainties, but believes it is well-positioned for multi-year expansion as demands for edge AI, autonomy, and sensor processing accelerate.

Takeaway: Positioned for Multi-Year Growth
OSS’s first quarter highlights—surging orders, rising gross margins, and positive cash flow—suggest that the company is delivering on its strategy of enabling edge computing for mission-critical applications. If the book-to-bill ratio translates to future revenue as planned, OSS could continue to scale up alongside advanced defense and commercial programs. With a strong balance sheet and growing pipeline, investors may want to watch how the company navigates volatility and sustains its current growth trajectory in one of tech’s most dynamic markets.
