Amboise SAS is the controlling and steering entity behind Altamir’s strategy, making it a key player in one of France’s best-known listed private equity structures. Within the Altamir governance framework, Amboise SAS has played a central role in shaping the company’s direction, particularly after the group’s capital was consolidated under a stronger control structure. In 2018, Amboise SAS, which is 100% owned by Maurice Tchenio, successfully completed its takeover bid for Altamir and increased its holding to 65% of the share capital. More recently, Altamir disclosed that, as of January 1, 2025, its investment advisory relationship would be transferred from Amboise Partners to Amboise SAS, underlining the company’s growing operational importance in the group’s strategic architecture. In 2025, Amboise SAS also crossed the two-thirds threshold of Altamir’s share capital and voting rights, reinforcing its ability to influence key corporate decisions and governance outcomes. Historically, Altamir was created in 1995 to give public investors access to private equity through a listed vehicle linked to Apax, later Seven2. In that environment, Amboise SAS has emerged as a control vehicle and strategic consolidator, supporting a long-term ownership approach. Its expertise lies at the intersection of listed private equity, corporate governance and capital transactions, with demonstrated experience in structuring complex ownership moves and maintaining strategic continuity for a specialized listed investment company.
