This proposed transaction, subject to the execution of definitive agreements, to applicable social procedures and the receipt of prior regulatory approvals, represents a key milestone in Shares’ strategic trajectory. In 2024, Shares expanded beyond its retail investment offering to provide technology to institutions in the wealth management and savings markets.

In a banking sector undergoing profound change, and with Banking-as-a-Service historically focused on payment-oriented use cases (banking, accounting tech, prop tech, and employee benefits), this merger aims to extend this model to the savings and investment markets. By combining its investment solutions with Treezor’s embedded finance offering, Shares aims to build a comprehensive, fully digital financial services platform to support the modernisation of financial institutions.

Subject to completion of the transaction, the proposed combination would create significant strategic value for both parties. Treezor would scale and enrich its platform, broadening its addressable market beyond core banking to include high-value savings and investment products. In parallel, the integration of Shares’ solutions would strengthen the newly formed group’s overall offering, delivering an end-to-end financial stack combining accounts, payments, savings, and investing.

“The entry into exclusive negotiations with Société Générale with a view to acquiring Treezor is a major step forward for Shares. Our objective is to build a solid and durable group capable of delivering a full range of financial solutions and playing a structuring role in the evolution of European digital finance.”

— Benjamin Chemla, CEO and co-founder of Shares.

Subject to completion of the transaction, Shares aims to become one of the leading players in the consolidation of European digital finance, in line with its mission to broaden access to investment.
