HawkEye 360 Establishes First European Subsidiary in Luxembourg

New EU entity reinforces HawkEye 360's long-term commitment to European customers, allies and industry partners

PARIS, Sept. 15, 2026 /PRNewswire/ -- HawkEye 360, Inc. (NYSE: HAWK), today announced the establishment of its first European subsidiary, HawkEye 360 Luxembourg, S.à r.l., marking an important step in the Company's expansion of operations in the European Union and reinforcing its long-term commitment to European customers, allies and industry partners amid an increasingly complex security environment.

The announcement coincides with an engagement between HawkEye 360 Chief Executive Officer John Serafini and U.S. Ambassador to Luxembourg Stacey Feinberg during World Space Business Week in Paris. The meeting underscores HawkEye 360's commitment to building a stronger operational presence in Europe and deepening its partnerships with government, industry and space-sector organizations across the region.

"Europe, its allies and our partners across the region are central to HawkEye 360's long-term strategy," said John Serafini, Chief Executive Officer of HawkEye 360. "The security environment is changing rapidly, and European nations need proven capabilities that can contribute to missions today. Establishing a European entity in Luxembourg strengthens our ability to work alongside governments and industry, support sovereign national requirements, and bring our proven space-based RF capabilities closer to the customers and partners who need them."

The Luxembourg subsidiary will serve as the foundation for HawkEye 360's expanded operations in the European Union, supporting closer engagement with European customers, governments and industry partners. The new entity provides a local base from which HawkEye 360 can build deeper relationships across Europe's defense and space ecosystem and collaborate more directly with European partners pursuing major emerging defense programs.

Operating an EU-based entity positions HawkEye 360 to participate more directly in Europe's evolving defense and space industrial ecosystem. By working from within the region, the Company is better positioned to collaborate with sovereign partners, work alongside European industry, and support solutions designed around European mission and security requirements.

"Luxembourg has built a strong and forward-looking space and defense ecosystem, making it an excellent partner for U.S. companies committed to supporting Europe's security, resilience and technological leadership," said Stacey Feinberg, U.S. Ambassador to Luxembourg. "HawkEye 360's decision to establish its European hub here reflects the strength of Luxembourg's growing space sector and creates new opportunities for collaboration."

HawkEye 360 provides proven space-based RF data and analytics that help defense and national security organizations detect, characterize, and understand activity across the radio frequency spectrum. As European nations strengthen their defense capabilities in response to evolving security challenges, HawkEye 360 can provide an operationally relevant RF layer that complements sovereign and allied systems, delivering unclassified, shareable insights to support situational awareness and informed decision-making.

"Our commitment to Europe starts with being closer to the customers and partners we support," said Todd Probert, Chief Operating Officer of HawkEye 360. "Europe's defense requirements are accelerating, and customers need capabilities that can be integrated and operationalized quickly. A European entity gives us a stronger foundation to collaborate directly with European industry, respond to major emerging defense programs, and integrate our proven RF capabilities with sovereign technologies and solutions developed within the region."
