One Stop Systems, Inc. reported strong top-line growth from its edge computing business in the quarter ended June 30, 2026. Continuing operations revenue rose to $9,348,551 from $5,760,711 a year earlier, a 62% increase, driven by new defense and industrial programs and higher customer‑funded development. For the first six months, revenue grew 59% to $17,418,162, with both product sales and funded engineering contributing.
Gross profit for the first half increased to $7,818,597, and gross margin improved to 44.9% from 43.3%, helped by efficiencies on development programs and better manufacturing absorption. However, the company accrued a $6,250,000 legal settlement related to a dispute with Disguise Systems and Disguise Technologies, which, together with higher stock‑based compensation, drove an operating loss of $7,671,881 in Q2 and a net loss of $7,319,659 for the quarter and $7,839,521 year‑to‑date.
Liquidity remains solid, with $17,279,139 in cash and equivalents, $14,128,617 in short‑term investments, working capital of $38,082,133, no debt, and a $2,000,000 undrawn credit line. Following the late‑2025 sale of its Bressner subsidiary, results now primarily reflect U.S. operations, with only a $157,274 loss from discontinued operations tied to post‑closing purchase‑price adjustments.
