What Inwido does

Inwido AB is Europe's largest window and door manufacturer, headquartered in Malmö, Sweden, and listed on Nasdaq Stockholm (ticker INWI) since September 2014. The company operates through a decentralized structure of 37 business units across 19 countries, manufacturing PVC, timber, and aluminum windows and doors tailored to regional specifications. Its customer base spans consumers, contractors, developers, social housing providers, and local government authorities, with a product range positioned around energy efficiency to align with EU Green Deal-driven retrofit demand. The group is organized into four business areas: Scandinavia (FY2025 revenue SEK 4,430M), West/UK-Ireland (SEK 1,774M), East/Finland-Poland (SEK 1,743M), and e-Commerce (SEK 1,071M), supported by a portfolio of 25+ acquired local brands including Sidey Solutions, Pihla Group, Victorian Sliders, Dekko, and Allan Brothers.

Inwido's product portfolio spans uPVC sliding sash windows, timber and aluminum casements, and entry doors, with technical capabilities including energy-rated designs and an on-site PVC recycling facility at the Victorian Sliders site in Wales — the group's first fully integrated manufacturing facility with closed-loop recycling. A scalable e-commerce platform supports direct-to-consumer sales across 11 European markets through 16 brands, with production concentrated in Estonia, Poland, and Romania. Notable technical and operational differentiators include local production enabling short delivery times, brand-led market positioning, and SBTi-validated science-based emissions targets that support premium positioning in EU retrofit tenders.

Revenue is generated primarily through one-time sales of customized window and door specifications via two channels: B2B sales to contractors, developers, and social housing providers (including multi-year public sector frameworks), and B2C sales to individual homeowners through both local showrooms and owned e-commerce platforms. FY2025 net sales were SEK 9,002 million (approximately USD 850M), with operating EBITDA margin of 10.5%, operating EBITA of SEK 941M, and net debt of 1.7x EBITDA. Growth is delivered through a combination of organic initiatives and serial bolt-on acquisitions, with management targeting SEK 20 billion in revenue by 2030 — implying approximately 15% CAGR from current levels.
