• Mayo Clinic, ranked #1 US hospital, adopts 4DMedical's CT:VQ™ technology
• 6th leading US Academic Medical Center to deploy CT:VQ™ in 7 months
• Deployment to support clinical workflow integration and clinician familiarity

4DMedical Limited, a global leader in respiratory imaging technology, has announced that Mayo Clinic, consistently ranked the number one hospital in the United States, has entered into an agreement for the use of CT:VQ™. Under the arrangement, Mayo Clinic will utilize CT:VQ™ for ventilation and perfusion analysis, enabling its clinical teams to build familiarity with the technology's advanced diagnostic outputs and assess its application across a range of clinical use cases. Mayo Clinic's decision to deploy CT:VQ™ represents one of the most significant institutional endorsements to date for 4DMedical's breakthrough respiratory imaging technology. As a globally respected and influential healthcare institution, Mayo's use of CT:VQ™ sends a powerful signal to the broader U.S. healthcare market about the clinical relevance and transformative potential of the technology. The deployment follows the successful commercial rollout of CT:VQ™ at five leading U.S. Academic Medical Centers: Stanford, Cleveland Clinic, UC San Diego Health, University of Chicago Medicine, and University of Miami. Mayo's engagement extends 4DMedical's footprint to six of the nation's most prestigious healthcare institutions, further reinforcing the Company's strategy of establishing CT:VQ™ at elite reference sites to drive broader market adoption. In approximately seven months since FDA clearance in September 2025, 4DMedical has now secured deployments at six of America's most respected Academic Medical Centers, reflecting the compelling clinical value proposition of CT:VQ™.

The Mayo Clinic deployment is strategically significant, as the institution's influence on clinical practice, treatment guidelines, and technology adoption across U.S. and global health systems is unparalleled. As Mayo's clinicians integrate CT:VQ™ into their workflows and develop confidence in its application, the institution has the potential to become a powerful reference site in 4DMedical's growing network, serving as a game-changing catalyst for broader commercial deployment. Combined with the Philips distribution partnership and 4DMedical's growing commercial pipeline, the Mayo deployment further strengthens the Company's position as it works to establish CT:VQ™ as the new standard of care in ventilation-perfusion imaging.
