WindowMaster: 2026 guidance points to back on track

WindowMaster International

In connection with yesterday’s adjustments to the 2025 guidance, WindowMaster has also provided guidance for 2026. The update points to a clear inflection in profitability, supported by improving order momentum and strong operational gearing.

For 2026, WindowMaster guides for organic revenue growth of 7–14% to DKK 290–310m and EBITDA of DKK 45–55m, implying an EBITDA margin of ~16–17%. This represents close to a doubling of margins year-on-year and highlights very strong operational gearing. In addition to the high operational leverage in the fixed salary-based project organisation, historical results also support earnings outpacing revenue growth by a wide margin, as EBITDA grew 93% in 2024 while revenue increased 24%.

The outlook and expectations of a gradually improving business environment during 2026 are partly supported by results and an order book that improved sequentially in H2 2025 compared to H1 2025.

From a valuation perspective, and assuming WindowMaster delivers on its 2026 guidance, the share trades at an appealing discount to the broader construction sector.

WWindowMaster offers advanced ventilation strategies, enabling the construction industry to significantly reduce its carbon footprint. Driven by the purpose ‘To create a better world where every person has fresh air indoors and a safe built environment’, the company develops, manufactures, and distributes facade and roof automation solutions for hybrid ventilation, natural ventilation, and smoke ventilation systems. Over the past four years (2020–2024), WindowMaster has delivered profitable growth with a 12% revenue CAGR, while improving both EBITDA and cash flow. The company’s performance has shown greater resilience than the broader building materials sector, underpinned by its exposure to the more stable renovation segment, the highly regulated smoke control market, and growing investments in the green transition. A disciplined capital allocation strategy has created substantial value through investments in innovation, own production capacity, and the global sales organisation. These initiatives have cemented WindowMaster’s strong market position across core markets in Europe and North America. With a robust platform for both organic and inorganic growth, WindowMaster is well positioned to create long-term shareholder value. In 2025, the company paid its first dividend since the IPO, reflecting its healthy financial foundation and commitment to shareholder value.
