InstallatrGruppen Completes Nasdaq Copenhagen IPO, Shares Begin Trading
InstallatørGruppen A/S, a Danish provider of multidisciplinary technical installation services, completed its initial public offering (IPO) on Nasdaq Copenhagen on 11 June 2026. The company’s shares, trading under the ticker IG and ISIN DK0064982565, opened for trading at 15 DKK per share.
The IPO involved the sale of 70 million shares at a fixed offer price of 15 DKK, giving the company a market value of roughly 4.5 billion DKK. The shares were sold by existing shareholders; InstallatørGruppen itself received no proceeds from the transaction. The offering attracted strong demand and was oversubscribed.
A total of 2,500 investors were allocated shares, with 4 % of the allocation reserved for retail investors in Denmark. The remaining shares were primarily allocated to Danish and international institutional investors. The principal shareholder, FSN Capital GP VI Limited, sold 57,445,743 shares on behalf of its various entities, including FSN Capital VI L.P., FSN Capital VI Invest L.P. and FSN Capital VI Lux SCSp.
In addition to the 70 million offer shares, the managers exercised an overallotment option for 10,499,850 shares, representing about 15 % of the offer. The option may be exercised within 30 calendar days after the first day of trading to cover overallotments or short positions. If fully exercised, the total number of shares placed in the offering would rise to 80,499,850, with a corresponding value of approximately 1.21 billion DKK.
The free float – the portion of the share capital held by new investors – is 25.8 % if the overallotment option is exercised in full, or 22.3 % if it is not. After the IPO, the principal shareholder will hold about 46.7 % of the total share capital and voting rights (or 49.5 % if the option is not exercised). The principal shareholder is subject to a 180‑day lock‑up period from the first day of trading, while other selling shareholders, including board members, executives and key employees, face a 360‑day lock‑up.
InstallatørGruppen’s CEO, Niels Eldrup Meidahl, said the listing was a milestone that reflected the strength of the business and its portfolio companies. Chair Jesper Teddy Lok added that the company was grateful to its new shareholders and thanked employees and portfolio companies for their commitment.
The IPO was managed by a syndicate of banks. ABG Sundal Collier Denmark, DNB Carnegie Investment Bank, Nordea Danmark and Skandinaviska Enskilda Banken served as joint global coordinators and bookrunners. Legal advisers for the company were Accura Advokatpartnerselskab and Davis Polk & Wardwell London LLP; the joint global coordinators and bookrunners were advised by Gorrissen Federspiel Advokatpartnerselskab and Milbank LLP.
Settlement of the offer shares is expected to occur on or around 15 June 2026 through Euronext Securities Copenhagen, with Euroclear and Clearstream handling the clearing and settlement. The offering is subject to the condition that it is not withdrawn before settlement and that the company makes an announcement confirming completion.
InstallatørGruppen, founded in 2023, operates through a network of independent companies in Denmark and Switzerland. Its services cover plumbing, heating, ventilation, refrigeration, electrical systems and specialist areas such as sprinkler systems, energy optimisation, building automation, fibre‑optic infrastructure and solar panel installations. The group aims to be a preferred partner for customers implementing the energy transition.
The company’s IPO marks the first step in a broader strategy to expand into new markets, with plans to enter a new market in 2027. Investors will now be able to trade the shares on Nasdaq Copenhagen, and the company will report its next financial results in the coming months.
The IPO announcement was issued under strict regulatory conditions, including a notice that the information is not an offer to sell securities in the United States and that the shares are not registered under the U.S. Securities Act. The release also contained detailed product governance statements for distributors in the European Economic Area and the United Kingdom.
In summary, InstallatørGruppen has successfully completed its IPO, raising 1.05 billion DKK from the sale of 70 million shares. The company’s shares are now publicly traded, and the principal shareholder retains a controlling stake. The next key events for the company will be its forthcoming earnings reports and any further corporate actions such as additional share issuances or potential acquisitions.
