Forvis Mazars appointed by Valcalorie SA shareholders

July 2025 | Valcalorie SA, a company specialising in the installation of ventilation, heating, and sanitary systems, has joined the Hälg Group, a family-owned business focused on building technology. The financial advisory teams at Forvis Mazars supported Mr. Stéphane Gaillard and the other shareholders of Valcalorie SA throughout every stage of the process, providing their expertise to successfully complete this strategic transaction.

Valcalorie SA operates across the entire lifecycle of HVAC systems – from planning through to maintenance – and offers tailored services for various types of facilities.

Established in Sion in 1965 and backed by a team of 30 skilled employees, Valcalorie SA has become a trusted and essential service provider in the Valais region.

Hälg Group is a Swiss family-owned company specialising in building technology and integrated Facility Management, employing over 1,240 staff across 28 locations throughout Switzerland.

The acquisition of Valcalorie SA by Hälg Group represents a strategic milestone for both companies: Hälg Group enters the Valais market and continues its strategy of sustainable growth, while Valcalorie SA gains the support of a strong partner to further develop its business with enhanced resources and expertise.

The shareholders of Valcalorie SA engaged the financial advisory team at Forvis Mazars – comprising Samuel Romailler, Emilien Isakov, and Neziha Halilovikj – to support them throughout the project.
