Dual-assay strategy designed to support outbreak response and surveillance efforts in affected regions

Potential blood-based Ebola assay would represent an important expansion of Co-Dx™ PCR point-of-care platform capabilities

SALT LAKE CITY , June 2, 2026 /PRNewswire/ -- Co-Diagnostics, Inc. (Nasdaq: CODX) ("Co-Dx" or "the Company"), a molecular diagnostics company with a unique, patented platform for the development of molecular diagnostic tests, today announced continued progress in its Ebola PCR development program with joint venture CoSara Diagnostics Pvt. Ltd. ("CoSara" or the "JV"). The program includes development of both a pan-Ebola assay designed to rapidly detect multiple ebolavirus species and a multiplex assay capable of differentiating among Sudan, Taï Forest, Zaire, and Bundibugyo ebolaviruses currently associated with outbreaks in Central Africa.

This dual-assay strategy is intended to provide flexibility in supporting outbreak response efforts, including those of potential NGO partners, subject to future development, validation, regulatory review, and deployment requirements.

"Our ability to rapidly develop and deploy molecular diagnostic solutions for emerging infectious disease threats is one of the most important differentiators of the Co-Dx platform," said Dwight Egan, Chief Executive Officer of Co-Diagnostics. "The progress we are making with Ebola reflects not only the flexibility of our assay design capabilities, but also the value of the international infrastructure we have built through CoSara. As outbreaks emerge around the world, combining rapid assay development with localized manufacturing and deployment capabilities positions us to respond quickly when new diagnostic needs arise."

The Ebola PCR assay workflow configurations also being developed to support point-of-care environments for the Co-Dx PCR point-of-care platform* would represent the first blood-based pathogen assay designed for use on the Co-Dx PCR Pro^®. This would significantly expand the platform's capabilities beyond swab-based infectious disease testing and increase the range of potential applications that may be addressed through future menu expansion.

Mr. Egan continued, "Many of the world's most serious infectious diseases are identified using blood samples, and expanding the platform to support those applications would represent an important step forward for Co-Diagnostics. The ability to bring rapid, high-quality PCR testing closer to patients, whether through respiratory, tuberculosis, HPV, or blood-borne disease applications, supports our broader goal of making molecular diagnostics more accessible in both developed and emerging markets."

*The Co-Dx PCR platform (including the PCR Home ^® , PCR Pro ^® , mobile app, and all associated tests) is subject to review by the FDA and/or other regulatory bodies and is not yet available for sale.
