One Stop Systems jumps 55% as rugged AI pivot drives record margins

One Stop Systems (NASDAQ:OSS) delivered a transformative first quarter for 2026, validating its strategic pivot toward high-margin ruggedized AI compute platforms.

The Escondido-based company reported revenue from continuing operations of $8.1 million, a 55% increase over the $5.2 million reported in the first quarter of 2025.

This growth follows the December 30, 2025, sale of its German subsidiary, Bressner Technology, for $22.4 million, a move designed to sharpen the company's focus on its core high-growth markets.

The quarter was highlighted by a record gross margin of 51.6%, a 610-basis-point expansion from the prior year.

This margin improvement was driven by a favorable product mix weighted toward specialized defense and commercial aerospace applications.

OSS reported a narrowed net loss from continuing operations of $0.4 million, while achieving a swing to non-GAAP net income of $0.3 million, or $0.01 per share—surpassing analyst estimates of a $0.05 loss per share.

The company's performance was bolstered by significant wins in the defense sector, notably its ongoing support for the U.S. Navy’s P-8 Poseidon aircraft.

OSS also secured $10.5 million in new awards from the Navy and a leading prime contractor during the period, bringing its total contracted revenue for the platform to over $65 million.

Overall, OSS generated nearly $15 million in new bookings during the quarter, resulting in a book-to-bill ratio of 1.8x.

This surge in orders was further supported by a $1.1 million initial order for in-flight entertainment systems and a new engagement with a commercial robotics customer for autonomous mining equipment.

Meanwhile, the divestiture of Bressner significantly fortified the company's balance sheet, which showed $34.4 million in cash and short-term investments as of March 31, 2026.

This liquidity supported a record $4 million in net cash provided by continuing operating activities during the quarter.
