QuidelOrtho Corporation (Nasdaq: QDEL) (the “Company” or “QuidelOrtho”), a global leader of innovative in vitro diagnostics, announced today it has completed the acquisition of LEX Diagnostics (“LEX”) for cash consideration of approximately $100 million. The LEX VELO System received U.S. Food and Drug Administration (“FDA”) 510(k) clearance and CLIA waiver in February 2026.

The LEX VELO System is a breakthrough molecular diagnostics platform that is designed to deliver highly sensitive, multiplex RT-PCR testing for Influenza A, Influenza B and COVID-19 directly from a swab sample in approximately six to ten minutes. Its proprietary cartridge-based design supports rapid clinical decision-making in decentralized care environments by eliminating the need for external liquid handling; delivering speed, reliability and ease of use. The acquisition of LEX marks a critical milestone in QuidelOrtho’s molecular diagnostics strategy to accelerate its growth in point-of-care molecular diagnostics by acquiring innovative technology within one of the fastest-growing segments of the diagnostics market.

“The FDA clearance of the LEX VELO System and the completion of our acquisition of LEX mark a pivotal moment for QuidelOrtho and for our customers,” said Brian J. Blaser, President and Chief Executive Officer of QuidelOrtho. “This ultra-fast PCR platform is designed to deliver lab-quality results in minutes and fits seamlessly into point-of-care workflows. It empowers providers to act faster, make better-informed decisions and ultimately improve patient outcomes. It also reflects our long-term commitment to bringing advanced diagnostics closer to the patient.”

Completing the acquisition of LEX expands QuidelOrtho’s molecular diagnostics portfolio while complementing the Company’s leadership positions in immunoassay, clinical chemistry and transfusion medicine. It reinforces QuidelOrtho’s ability to deliver integrated diagnostic solutions across the continuum of care, from point of care to hospital, lab to clinic.

“LEX achieved an extraordinary milestone with FDA clearance and CLIA waiver of the LEX VELO System,” said Ed Farrell, Chief Executive Officer of LEX. “We are proud to join QuidelOrtho and to bring this technology to customers worldwide. We believe we can redefine what is possible in point-of-care molecular diagnostics.”

QuidelOrtho expects to initiate the U.S. commercial launch of the LEX VELO System later this year. Global expansion is expected to follow, subject to local regulatory approvals.
