Sentinel Holdings Ltd focuses on providing armed and unarmed security services in California through its Sentry and USS subsidiaries, with Gladiator largely dormant due to litigation. Revenue for the year ended December 31, 2025 rose 10% to $5.07 million, while gross margin improved to 26% as the company shifted toward higher‑margin contracts.
Despite better margins and reduced operating expenses, Sentinel still posted a loss from operations of $4.46 million and a net loss attributable to common shareholders of $1.66 million, helped by a $2.21 million Business Reassessment and Repositioning Adjustment and a gain on an OPSEC contract acquisition. Cash was only $197,165 with a working capital deficit of $4.19 million, an accumulated deficit of $23.96 million, and an auditor going‑concern warning, meaning continued operations depend on raising additional capital and executing its acquisition‑driven growth plan.
