WISeKey Appoints Gwenael Rouy-Poirier as Chief Financial Officer of WISeSat, its Satellite Connectivity Subsidiary
Geneva, Switzerland, February 10, 2026 – WISeKey International Holding Ltd (“WISeKey” or the “Company”) (SIX: WIHN, Nasdaq: WKEY), a global leader in cybersecurity, digital identity and Internet of Things (IoT) solutions, today announced the appointment of Gwenael Rouy-Poirier as Chief Financial Officer of its subsidiary WISeSat.Space Corp. (“WISeSat”) specialized in space-technology and secure satellite communications for IoT applications, effective February 2, 2026.
Of note, in November 2025, WISeSat announced a Business Combination Agreement with Columbus Acquisition Corp. (Nasdaq: COLA), a Cayman Islands–based public SPAC, paving the way for WISeSat to be listed on the Nasdaq Stock Exchange.
In his role, Mr. Rouy-Poirier will lead WISeSat’s finance, strategy and capital-markets activities as the business enters its next phase of growth as a secure satellite communications platform focused on IoT, defense and critical infrastructure applications. He will play a central role in strengthening financial governance, driving execution discipline, and enhancing investor readiness, while advancing value-creation initiatives that support WISeSat’s long-term ambition to scale its satellite-based secure connectivity services globally.
Mr. Rouy-Poirier brings over 25 years of international finance and operational leadership experience across aerospace, defense, industrial technology and advanced manufacturing, spanning both listed and private-equity-owned environments. He has held senior Group and divisional CFO roles at global industrial leaders including GKN Aerospace, Honeywell and Danaher, and has led complex transformation, restructuring, M&A and capital-markets initiatives across Europe, North America and Asia.
Mr. Rouy-Poirier currently serves as a board member and audit committee member of Coda Octopus Group (Nasdaq: CODA), a listed defense technology group, and sits on the Advisory Board of Bridgology, a Swiss-based infrastructure SaaS scale-up. Most recently, he has advised industrial and technology businesses on strategic finance, value creation and transaction execution. He brings deep experience in governance, investor communication and scaling finance organizations in regulated and capital-intensive environments, capabilities directly relevant to WISeSat’s positioning at the intersection of space, defense and critical infrastructure.
Mr. Rouy-Poirier holds a Master’s degree from EDHEC Business School, a French Baccalauréat in Mathematics and Science, and is a qualified private pilot.
Mr. Rouy-Poirier commented: “I am delighted to join WISeSat at this important stage of its evolution, as it prepares for its planned listing on the Nasdaq. Secure satellite connectivity is becoming a critical enabler for defense, IoT and sovereign infrastructure, and WISeSat occupies a unique position within the WISeKey ecosystem. I look forward to working with the team to strengthen financial discipline, support growth and ensure WISeSat is well positioned to meet the expectations of U.S. public-market investors, while delivering long-term value for stakeholders.”
Carlos Moreira, Founder and CEO of WISeKey, commented: “We are very pleased to welcome Gwenael as CFO of WISeSat at a pivotal moment in its development. His extensive experience as a senior finance leader in complex, technology-driven and highly regulated industries bring exactly the rigor, credibility and execution focus required, as WISeSat scales its operations and engages with the capital markets. Gwenael will be a key partner to the management team as we build a robust and financially disciplined satellite platform.”
John O’Hara, CFO of WISeKey, noted, “Gwenael joins us as CFO of WISeSat at an important time for the satellite communications industry, as demand for resilient, high-performance connectivity continues to accelerate. Gwenael’s depth of financial leadership and experience supporting capital-intensive, technology-driven businesses will be instrumental as we scale our capabilities and invest in our growth. I look forward to working closely with him as WISeSat prepares for the next phase of becoming a public company.”
