Geneva - October 16, 2023 – WISeKey International Holding Ltd. (“WISeKey”) (SIX: WIHN, NASDAQ: WKEY), a global leader in cybersecurity, digital identity, and Internet of Things (IoT) solutions operating as a holding company, today announced that its partner, PLD Space, in an exciting advance for the space industry and technological innovation, is transforming the landscape in Spain and placing Elche, Teruel, and Huelva at the epicenter of the global space revolution. In the early hours of October 7, a historic milestone materialized with the successful launch of the first privately Spanish rocket into space: Miura 1. This achievement marks a turning point in Spain and Europe's independence in the field of satellite launches, quantum communication security, and low-orbit satellite design and manufacturing.

This goal, initially seeming virtual, is now becoming a reality with tangible results from companies like WISeKey, Fossa, and PLD Space. These companies, with their respective technologies, are paving the way toward creating the first phase of the Center for the Fourth Industrial Revolution.

With an estimate of 3,000 million connected objects in the coming years, the space revolution led by these entrepreneurs from Elche promises to transform the world of connected objects. Spain is on the path to becoming key players in the space and technological industry, and their bold vision is opening new frontiers in space and innovation in the fourth industrial revolution. This exciting journey promises to change the way we view space and its role in our future.

While the term "commercial space economy" has often been used without a clear definition of its limits in its initial stages, this multifaceted industry goes far beyond space tourism and continues to expand.

In 2021, the global space economy as a whole was estimated to reach $469 billion, an increase of over 60% compared to estimates made just a decade earlier. According to BofA Global Research's perspective, this growth trend is likely to continue, reaching approximately $1.1 trillion by the year 2030.

What drives this growth? While it's clear that governments around the world no longer have a monopoly in space, they continue to be key drivers of investment. In fact, the European Union (EU) announced in early 2022 that it will invest approximately $15 billion over the next five years in space exploration programs, Earth monitoring, and satellite launching.

This growth in the commercial space economy is due to a series of factors, including not only the expansion of space tourism but also the boom of new space companies that are developing innovative technologies, such as low orbit satellites for global connectivity and the rise of space mining. In addition, growing international collaboration on space projects is opening new opportunities and horizons.

The commercial space economy is a rapidly growing field that encompasses much more than space tourism, and its growth potential is significant thanks to ongoing government investment and technological innovation. Space has become fertile ground for exciting business opportunities, and the future of this industry promises to be extraordinary.
