VKR Holding, the Danish parent of roof-window maker VELUX, has agreed to acquire French building-products group StellaGroup from private equity firms PAI Partners and ICG, the companies said on 6 November 2026. Financial terms were not disclosed.
Why VKR Holding A/S is buying StellaGroup
VKR said StellaGroup would become a third business area alongside the VELUX Group and DOVISTA Group, extending its presence in products that manage daylight and indoor climate. StellaGroup will keep its name and management team.
“We are delighted to be adding a third business area to VKR Holding.”
Deal terms and financing
PAI Partners, the majority owner, ICG and management are selling. PAI described the deal as an offer by VKR to acquire StellaGroup, the usual French structure pending works-council consultation, while VKR said it had signed an agreement.
Regulatory approvals and timing
Completion is subject to information and consultation of StellaGroup's employee representative bodies and customary regulatory approvals.
