WISeKey International Holding AG reported a 58% increase in total revenue to $19 million for fiscal year 2025, driven largely by the post‑quantum semiconductor subsidiary SEALSQ, which accounted for roughly 95% of the company’s sales. The growth was supported by strong demand for SEALSQ’s chips and the company’s expanding satellite and blockchain platforms.
The company posted a net loss of $38.2 million for the year, a figure that reflects the heavy investment in research and development, sales and marketing, and the integration of the IC'ALPS acquisition, which contributed about $3.5 million to revenue. The loss underscores the ongoing cost of scaling the new product portfolio and expanding the satellite constellation.
Revenue from SEALSQ rose sharply, while the satellite and blockchain segments contributed modest but growing amounts. The acquisition of IC'ALPS added a new revenue stream and broadened SEALSQ’s product offering, reinforcing the company’s position in the post‑quantum market. Satellite operations continue to expand, with the 21st satellite launched in March 2026, and the company aims to reach 100 satellites by 2027.
Management reiterated its 2026 guidance, projecting revenue growth of 50% to 100% year‑over‑year. The outlook is anchored by the commercial launch of the QS7001 microcontroller and the expansion of the satellite constellation, both expected to drive significant revenue in the coming year.
"The 58% revenue growth for WISeKey achieved in 2025 and the strong start into 2026 clearly demonstrate the transition of our semiconductor and post‑quantum strategy from investment to commercial acceleration. With exceptional liquidity, a rapidly expanding pipeline, and rising global demand for sovereign, quantum‑resistant infrastructure, WISeKey and SEALSQ are uniquely positioned to lead the next generation of secure digital ecosystems," said CEO Carlos Moreira.
The company’s cash position, exceeding $425 million at year‑end, provides a solid financial cushion to support continued investment in product development and satellite expansion, while the guidance signals confidence in sustaining high growth momentum in the post‑quantum and secure connectivity markets.
