WISeKey Raises Revenue Guidance for Full Year 2023


Zug, Switzerland – November 15, 2023 – Ad-Hoc announcement pursuant to Art. 53 of SIX Listing Rules– WISeKey International Holding Ltd. (“WISeKey”) (SIX: WIHN, NASDAQ: WKEY), a leader in cybersecurity, digital identity, and Internet of Things (IoT) solutions operating as a holding company, today updated its full year (“FY”) 2023 revenue guidance to over $30 million, which represents an increase by over 25% compared to revenue reported for FY 2022.


For the nine-month period ended September 30, 2023, WISeKey’s total unaudited revenue was $22.6 million, marking a 21% increase from the nine-month period ended September 30, 2022. Of note, the semiconductor segment revenue saw a 20% increase to $22.1 million from $18.4 million in the nine-month period ended September 30, 2022.


WISeKey operates as a holding company with four subsidiaries: SEALSQ Corp (“SEALSQ”) (Nasdaq: LAES), WISeKey SA, WISeSat.Space, and WISe.ART, each dedicated to a unique aspect of its expansive technology portfolio, is also reporting a pipeline of opportunities for IoT semiconductors products totaling $60 million.


WISeKey’s diversified growth strategy is beginning to bear fruit, as evident from the accelerated progress at its semiconductors and cybersecurity sectors now delivering supply chain logistics projects, such as the innovative Smart Container initiative, and the increased level of investments and demand for WISeSat.Space related services and blockchain tokenization for the WISe.ART Digital Platform. While cybersecurity and semiconductors remain WISeKey’s primary revenue sources, these new ventures are demonstrating significant potential.


Carlos Moreira, CEO of WISeKey, discussing this revenue evolution, stated, “We are witnessing a strong and consistent customer demand for our cybersecurity, semiconductor products and Matter-related offerings, along with a growing market share. Our innovation efforts are especially noteworthy in areas like integrating semiconductors with post-quantum technologies, artificial intelligence, security, and cloud services. This progress strengthens our belief in our ability to capitalize on the numerous opportunities that lie ahead.”


Looking forward, Mr. Moreira added, “While 2024 is projected to be a year of transition for the WISeKey group, marked by a temporary slowdown in growth due to market shifts toward emerging new semiconductors at SEALSQ level, we are slowly but surely introducing new revenue sources from other verticals. In 2025-2026, we expect to see full production recovery and revenue surge in semiconductors, in additional to meaningful revenues to be generated from new verticals.”





Mr. Moreira continued, “Specifically, in 2024, we are strategically positioned to start generating revenue from our innovative Low Orbit satellite initiatives, notably in projects like Smart Container and Supply Chain supervised by satellite connections. Additionally, we are introducing a novel offering that encompasses the establishment of dedicated centers for cybersecurity and IoT Semiconductors personalization. This is a significant step in enhancing our service portfolio and meeting the evolving needs of our clients. Moreover, 2024 is set to be a pivotal year for our WISe.ART platform, as it is expected to reach full maturity and begin generating substantial transactional revenue. This growth will be driven by the rich collection of digital art already hosted on the platform, which we anticipate will attract significant interest and engagement from the digital art community. Looking further ahead, our sustained investments in the research and development of post-quantum resistant technology are projected to yield considerable returns starting from 2025/2026. This advancement is crucial in keeping pace with the rapidly changing technological landscape and maintaining our leadership in providing cutting-edge, secure solutions in an increasingly digital world.”
