About Allied Universal
Allied Universal® is the world’s largest security and facility services company — a Conshohocken, Pennsylvania and Irvine, California dual-headquartered private enterprise providing security guarding, technology solutions, janitorial services, and risk consulting to clients across virtually every major industry. Founded in 2016 through the merger of AlliedBarton Security Services and Universal Services of America, Allied Universal has grown at an extraordinary pace under Global Chairman and CEO Steve Jones — who built the company from $12 million in revenue to more than $23 billion through aggressive organic growth and 70+ acquisitions including the landmark £3.8 billion acquisition of UK-based G4S in 2021. Allied Universal employs approximately 800,000 professionals worldwide — making it one of the largest private employers on earth — operating at more than 127,000 client sites across 90+ countries.
Allied Universal is actively pursuing a potential IPO, with CEO Steve Jones stating in May 2026 that 2026 is the earliest the company would seriously consider going public — pending completion of its internal AI transformation around scheduling, recruiting, and workforce management. The company generated approximately $23 billion in revenue in 2025, completing nine acquisitions in fiscal 2025 with combined revenue of approximately $640 million, and has announced three additional acquisitions in 2026. Allied Universal won the 2026 Transformative CEO Award from the CEO Forum Group for Steve Jones.
