This filing provides a comprehensive update on the strong financial and operational performance of SEALSQ Corp, a key subsidiary of Wisekey International Holding S.A. While a preliminary announcement was made on January 14, 2026, this filing adds significant detail regarding SEALSQ's FY 2025 results, including specific net loss figures, an exceptionally strong cash position, and detailed Q1 and full-year 2026 guidance. The reported 66% year-over-year revenue growth for FY 2025, coupled with expectations for over 100% growth in Q1 2026 and 50-100% growth for FY 2026, signals strong commercial momentum.
