InstallatørGruppen A/S (Ticker: IG DC) is a Danish provider of multi-disciplinary technical installation services, operating in Denmark and Switzerland through a decentralized network of locally anchored portfolio companies. The company provides installation, service and maintenance of technical systems across residential, commercial, industrial and public-sector end markets, including electrical installations, heating, ventilation, cooling, building automation, solar installations and fire safety solutions.

InstallatørGruppen plans to list on Nasdaq Copenhagen on June 11, 2026. According to published terms, the company is offering 70.0 million existing shares at DKK 15.00 per share, raising DKK 1.05 billion, or approximately $163 million. The implied market value at the offer price is DKK 4.5 billion, or approximately $698 million.

The offering consists entirely of secondary shares sold by FSN Capital-related funds and around 300 minority shareholders, so the company is not expected to receive IPO proceeds. The selling shareholders have granted a 15% overallotment option of up to 10.5 million additional shares, which would increase the offering to DKK 1.2 billion if exercised in full. The group was established in 2023 and has completed 47 acquisitions.
