Sales - 2025
JP MANGEANT, a regional leader in the installation of heating, ventilation, air-conditioning (HVAC) and plumbing solutions, today announced that it has joined Compagnie Financière Armoricaine, a specialist in the construction of new housing, student residences and serviced residences. This transaction was carried out with the support of Largillière Finance, and will create a major player in the Grand-Ouest region.
Founded in 1980 by Jean-Pierre Mangeant and managed since 2010 by his son, Stéphane Mangeant, the company specializes in the installation of HVAC and plumbing solutions for new construction projects. JP MANGEANT is based in Pocé-sur-Cisse near Tours (37) and in Nantes (44), and carries out large-scale projects in the Pays de la Loire region, ranging from 50 to 250 homes, for renowned property developers such as Nexity, Kaufman & Broad and Edouard Denis. With a solid order book of 28 projects underway, operated by 55 employees, and over €10 million in sales secured for the coming months, the company has strong growth prospects.
Based in Brittany, Pays de la Loire and Ile-de-France, Compagnie Financière Armoricaine (CFA), which also owns ISF Energies and Sogec Energie, is a group specializing in the construction of new multi-family housing, student and service residences and ERP (offices, hotels, etc.). With sales of over €30 million, Compagnie Financière Armoricaine delivered 2,520 housing units in 2022 and employs over 150 people.
Recognized for its expertise and strong presence in the Centre-Val de Loire and Pays de la Loire regions, JP Mangeant strengthens CFA's position in these regions, which offer significant growth prospects.
As part of this acquisition, Stéphane Mangeant will retain a minority share in the company's capital, and will continue to manage JP MANGEANT within CFA, in order to contribute to the group's growth dynamic.
According to Thomas Bureau, Managing Partner at Largillière Finance: “We are delighted to have supported JP MANGEANT in this transaction, as we are convinced that it will enable them to benefit from the backing of a solid and innovative group, offering enhanced prospects for accelerating their development and consolidating their position as leader in the HVAC and plumbing sector. This sale also guarantees a lasting handover and optimal support for the company’s growth strategy“.
With more than 40 employees, a strong international presence and nearly 30 operations in 2023, Largillière Finance confirms its leader position in small and midcap in France.
