Private equity firm PAI Partners and Italy’s sovereign wealth vehicle Fondo Italiano d’Investimento have signed a deal to purchase Mecaer Aviation Group from the holding arm Fondo Italiano Consolidamento e Crescita and Stellex Capital Management. Mecaer, a specialist in flight‑critical systems, will join a consortium that also includes LGT Capital Partners and the company’s own management team, and will reshape its capital structure.

Last year Mecaer generated €242 million in revenue, underscoring its strong position in the aerospace supply chain. The founding families have agreed to roll over a portion of their equity alongside the new investors, signalling confidence in the growth plan that targets higher‑margin components and broader certification programmes. The deal also aligns Mecaer with EU defence initiatives, opening avenues for funded projects.

The transaction, valued in the low‑hundreds of millions, gives PAI Partners a foothold in Europe’s high‑tech aviation sector and provides Mecaer with capital to accelerate R&D and expand its global customer base. Investors will watch how the combined backing translates into market share gains as OEMs tighten supplier requirements. The financing package includes a revolving credit line to support working‑capital needs during the transition.
