ESCONDIDO – One Stop Systems Inc. (Nasdaq: OSS), a military electronics maker and edge computing specialist, ended 2025 by selling its German business, Bressner Technology GmbH, to Hiper Euro GmbH, part of Israel-based Hiper Global, for approximately $22 million. The deal was announced Dec. 30.
OSS President and CEO Mike Knowles called the transaction “an important milestone in our evolution.” With it, the company slims down from approximately 110 employees to 60.
Knowles said the acquisition went quickly and efficiently, and OSS expects the transaction to benefit shareholders by generating a pre-tax gain of approximately $7.4 million to its fourth-quarter results, before accounting for transaction expenses.
The business said the sale would simplify OSS’s operating model and position it to focus entirely on the fastest-growing and most profitable segments of the business, including deployable AI, real-time sensor processing and rugged edge-computing systems engineered for mission-critical defense and commercial environments. OSS says its products bring data center performance to harsh and challenging applications.
OSS had owned Bressner since 2018. Based in the Munich suburb of Puchheim and serving markets in Europe and the Middle East, the business is more of a value-added reseller and distributor – which is not OSS’s current core business. Knowles said that at the time OSS bought it, Bressner offered an opportunity to grow revenue. Under OSS, Bressner sales grew from $18.3 million in 2019 to approximately $33 million (on a trailing 12-month basis as of Sept. 30).
Knowles arrived in 2023 from Cubic Corp. and put more of an emphasis on military sales.
Today OSS’s sales are split evenly between government and commercial, he said, though that varies from quarter to quarter. Going forward, the CEO said he would like to increase international sales, starting with the “Five Eyes” countries of Australia, Canada, New Zealand and the United Kingdom. All five in the intelligence-sharing alliance use similar architecture, Knowles said.
“We’re excited about the momentum we’ve generated in the last couple years,” Knowles said in an interview Jan. 21. The business hopes to compete for larger programs and is looking at M&A, according to a statement.
OSS products are ruggedized to withstand shock and vibration. Such electronics can help a vehicle navigate in battle zones where GPS service is knocked out.
In other news, the company expects to report full-year results soon. As a preview, the company said it expected quarterly revenue of $30 million to $32 million.
OSS also said in early January that it received an approximately $1.2 million pre-production order from a new U.S. defense prime contractor for the design, development and delivery of ruggedized integrated compute and visualization systems for U.S. Army combat vehicles.
