Allshares has acquired Stock & Option Solutions (SOS), a U.S.-based specialist in equity compensation and stock plan administration, as the company pushes deeper into what it called its largest and fastest-growing market. The deal adds a long-standing U.S. services platform to Allshares’ ownership management software and positions the combined organization to support clients operating across multiple countries and equity technology systems.
Founded as a platform and services provider focused on designing and administering equity incentives, Allshares said SOS strengthens its ability to deliver end-to-end ownership management for customers ranging from startups to large enterprises. SOS, which has supported equity and compensation plans for more than 25 years, operates a platform-agnostic service model intended to help companies manage complex incentive structures across major equity systems.
The acquisition is intended to accelerate Allshares’ U.S. expansion while extending SOS’ reach through Allshares’ international footprint. Allshares said the integration of SOS’ U.S. plan administration capabilities is a strategic milestone in its broader international growth strategy, enabling more seamless delivery for organizations with cross-border ownership programs.
Allshares said it is backed by Bregal Milestone, which provides growth capital and operational support. Following the transaction, SOS will continue operating under its existing brand as a subsidiary of Allshares, maintaining current services and client relationships.
Financial terms were not disclosed, and the transaction remains subject to customary closing conditions.
