The Chesneau-Serret Group, a leading player in high-precision mechanics, takes a new step forward with the acquisition of LGB, a specialist in machining complex parts. This transaction, carried out with the support of Weinberg Capital Partners through its Eir\u00e9n\u00e9 fund \u2014 the group\u2019s majority shareholder \u2014 and UI Investissement, marks a defining moment in Chesneau-Serret\u2019s development. It will enable the group, led by David R\u00e9mongin and Am\u00e9lie Pichol, to strengthen its offering, diversify its client portfolio, and reach a critical size.<\/strong><\/p>\n\n\n\n


Two leading players in the precision mechanics market<\/strong><\/h2>\n\n\n\n

Founded in 1965, Chesneau-Serret has established itself as a leading player in high-precision mechanics in France. The group designs and manufactures critical parts with complex geometries for demanding sectors such as civil and military aeronautics, as well as the medical industry. It relies on a team of nearly 100 employees spread across two sites located in Haute-Marne (Grand Est) and Dr\u00f4me (Auvergne-Rh\u00f4ne-Alpes).<\/p>\n\n\n\n

Founded in 1967, LGB specializes in multi-axis machining of precision mechanical parts for the defense and aeronautics industries. Based in the Centre-Val-de-Loire region, the company offers a wide range of expertise at its 3,000-square-meter site, which brings together nearly 40 employees: machining, electrical discharge machining, grinding, dimensional inspection, and associated services. The group also has a design office, enabling it to finalize the development of parts requested by clients when needed.<\/p>\n\n\n\n

A merger built on shared DNA and technical excellence<\/strong><\/h2>\n\n\n\n

This upcoming merger is based on strong technical and commercial complementarity between the two companies. It will allow Chesneau-Serret to expand its client portfolio and service offering while increasing its production capacity.<\/p>\n\n\n\n

Already well-known in its markets, Chesneau-Serret is thus consolidating its position with major contractors in the defense and aerospace sectors.<\/p>\n\n\n\n

Following the transaction, the group will reach a turnover of nearly \u20ac25 million.<\/p>\n\n\n\n

An operation supported by the group’s shareholders<\/strong><\/h2>\n\n\n\n

This merger comes less than a year after Eir\u00e9n\u00e9\u2019s entry into Chesneau-Serret\u2019s capital and is fully aligned with the fund\u2019s sector consolidation strategy. <\/p>\n\n\n\n

The transaction is expected to be finalized by the end of 2025, subject to the usual conditions precedent.<\/p>\n\n\n <\/div>\n <\/div>\n <\/div>\n\n
