SoftBank Group Corp. is in preliminary discussions to acquire Allied Universal, the largest security services firm in the United States. The potential deal could value the company's equity at up to $18 billion, with an additional $12 billion in public debt, bringing the total enterprise value to nearly $30 billion.

Following the news on October 16, 2026, SoftBank's American Depositary Receipts (SFTBY) declined by approximately 9.5% to 10%. Investors expressed concerns regarding the deal's scale, the company's existing financial commitments, and the integration of labor-intensive, low-margin security operations into SoftBank's portfolio.

Allied Universal is currently backed by investors including Warburg Pincus and the Canadian pension fund manager La Caisse de dépôt et placement du Québec. Any acquisition would require their approval, though their current position on a potential sale remains undisclosed.

SoftBank aims to leverage Allied Universal's infrastructure and workforce to integrate AI and robotics into physical environments. The firm views this as a way to create a real-world testing ground for its technologies, including future deployments of humanoid robots and physical protection for data centers.

This potential acquisition follows other significant capital allocations by SoftBank, including a $30 billion commitment to OpenAI and the $5.4 billion acquisition of ABB’s robotics business. No final decisions regarding the price or structure of the Allied Universal deal have been made.
