Ardian takes majority stake in Diam
Context
This transaction represents the enterprise's fifth consecutive Leveraged Buyout (LBO), marking a significant yet familiar restructuring of its cap table. The incoming lead financial sponsor steps in to successfully provide an exit for several incumbent minority investment funds. A defining characteristic of this operation is the massive, broad-based reinvestment from the executive leadership and a vast cohort of key employees, ensuring profound strategic alignment. The overall capitalization is robustly structured, featuring a comprehensive senior debt package syndicated across multiple tranches by an expanded consortium of historical banking partners. Crucially, this financing architecture includes substantial, dedicated acquisition credit lines strictly earmarked to rapidly trigger an aggressive, inorganic external growth campaign immediately following the successful completion of the customary regulatory closing conditions.
In the past, the company had already been the subject of several LBOs, notably led by Ardian in 2016 and EMZ Partners / BNP Paribas Developpement / Idia Capital Investissement in 2018. These multiple LBO cycles illustrate the strong appeal for this type of asset.
Diam, which reported an EBITDA margin of [members only] in 2023, is valued in this transaction at an EV/EBITDA multiple of 5x–12x, standing directly in line with the average observed in the Business Services sector (10.4x in 2024).
