12/2025HOLCIM GROUPALKERNFRANCEChemicals & Materials

Holcim has finalized the 100% acquisition of Alkern from the private equity firm Chequers Capital. This transaction marks the final exit for Chequers, which had supported Alkern’s growth since 2016. The strategic rationale for Holcim is the immediate reinforcement of its "Construction Solutions" pillar in the French market, positioning it alongside its existing Lafarge and PRB operations. The deal received clearance from the French Competition Authority in late December 2025. Alkern will maintain its operational autonomy, brand identity, and current management team led by Xavier Janin. The merger is designed to capture €11 million in EBITDA synergies by the third year, primarily through commercial cross-selling and operational optimization with Holcim’s sister companies. Access to Holcim’s global R&D center in Lyon will further accelerate Alkern’s innovation in carbon-capture concrete and water management infrastructure. This acquisition also includes the joint control of specialized entities EVBME and Sofama Vermeulen, broadening Holcim’s reach into niche molding and materials markets.

Sacred Group has finalized a majority BIMBO, valuing the company at less than €30 million. The transaction sees industrial partner Stéphane Tortrat take a 60% stake, integrating his company Fenec into the new entity. Historical backers Bpifrance and BNP Paribas Développement remain in the capital, while former majority owner reduced his stake from 75% to 9%. The strategic rationale is to reduce Sacred’s exposure to the automotive sector by leveraging Fenec’s non-auto client base in aerospace, defense, and medical sectors. The merger creates a consolidated group with €75 million in revenue and a strong international presence (40% outside Europe). The deal was supported by senior bank debt provided by Bpifrance Financement, Crédit Agricole, and Société Générale.

The deal is financed through an equity ticket of EUR 20–30 million and a unitranche debt facility provided by BNP Paribas AM, representing a leverage of approximately 3.0x EBITDA. The strategic rationale is to leverage the acquirer’s deep network in the food industry to accelerate Sopano's growth, with the ambition of doubling its turnover in the coming years.

For Fibo, the acquisition provides access to greater resources and the ability to collaborate with a larger group to further serve global customers.
