Weinberg Capital Partners announces a new closing of €275 million for its Eiréné fund, dedicated to defense and security

Weinberg Capital Partners, a leading private equity firm in the small and mid-cap segment in France, announces that it has reached a new milestone for its Eiréné fund, which now stands at €275 million in commitments. This new closing, representing more than €60 million in additional commitments, confirms the attractiveness and relevance of the fund’s investment strategy.

Launched in 2020, Eiréné is the first LBO fund specifically dedicated to supporting SMEs and mid-cap companies in the defense and security sector. After an initial closing of €100 million in February 2023, followed by a second closing of €215 million in February 2025, the fund was reopened with the agreement of its existing investors in order to respond to numerous requests from institutional and private LPs wishing to participate in this project. This operation has enabled new investors, including some international ones, to come on board, demonstrating the growing interest in this strategic sector.

Under the leadership of Lionel Mestre, Partner and Managing Director of Eiréné, the team, composed of defense and finance specialists, has already completed four transformative acquisitions:

• Semip-Codechamp, European leader in high-performance angular position sensors;
• Chesneau Serret, recognized specialist in high-precision mechanics;
• Magellium Artal, an expert in satellite image processing and digital mapping;
• Groupe Adit, a key player in strategic intelligence and economic sovereignty.

Eiréné’s investment thesis is based on acquiring stakes in SMEs and mid-cap companies from the Defense Industrial and Technological Base (BITD) in order to support and accelerate their development. The objective is to build industrial champions capable of sustainable growth in France and internationally, leveraging structural strengths:

• technological excellence;
• fast-growing markets in France and abroad;
• a dual positioning (civilian and defense) that promotes growth and diversification;
• strong external growth potential in a sector that is still fragmented.
