Gurit

What Gurit does

Gurit Holding AG is a Swiss-listed supplier of advanced composite materials, engineering services, and tooling for the wind energy, marine, and industrial markets. Its core offering spans structural core materials (PET/Kerdyn PET, Corecell SAN foams, Balsaflex end-grain balsa, PVC foam), prepregs with proprietary SPRINT dry-fiber/resin-film technology, and a formulated epoxy range (Spabond, StrucPro, BondPro, Ampreg, PRIME, AMPRO), together with glass pultruded components, wind blade molds, and manufacturing automation. The OptiCore parametric design platform performs thousands of simultaneous optimizations to produce precision-engineered core kits containing over 1,600 components per blade, integrating materials supply with engineering IP.

The company monetizes through direct enterprise sales of materials, recurring multi-year kitting supply agreements with wind turbine OEMs, engineering and design services, and capital equipment (molds, automation). A flagship CHF 250 million five-year core kitting supply agreement with a leading wind OEM, based on OptiCore, anchors the order book alongside a separate Asia-Pacific pultruded blade-root contract and a multi-year subsea Corecell S contract. Distribution is supported by 27 strategically located fulfilment and manufacturing sites in Europe, Asia-Pacific, and the Americas. Gurit reported FY2025 net sales of CHF 319.6 million (exceeding CHF 300 million guidance), core EBIT of CHF 26 million (8.1% margin, +110bps YoY), and equity free cash flow of CHF 11 million, with net debt reduced to CHF 55 million.

The company's customer base is anchored by global wind turbine OEMs, marine yards (racing yachts, superyachts, commercial, military, and the Ika Rere electric ferry), and industrial composite manufacturers. Major product lines carry DNV, Lloyd's Register, ABS, RINA, BV, and IRS certifications, while Kerdyn PET enables up to 65% lower CO2 emissions versus conventional foam cores through a closed-loop recycling system processing nearly one billion post-consumer PET bottles annually. Gurit has operated under a transformation program in 2025 that absorbed CHF 69 million in restructuring costs, with new executive leadership (CEO Tobias Lührig from July 2025, CFO Viktor Bernhardt from December 2025) overseeing the next phase.
