About 20/20 Biolabs

We develop and commercialize AI-powered, laboratory-based blood tests for the early detection and prevention of cancers and chronic diseases. We offer two families of lab tests, both under our OneTest brand: (i) OneTest for Cancer, a multi-cancer early detection, or MCED, blood test which has been our primary commercial focus and source of revenues since we wound down our COVID-19 testing business, and (ii) OneTest for Longevity, which measures inflammatory biomarkers, that we expect to launch in the first half of 2026. Both tests are run in our CAP (College of American Pathologists) accredited, CLIA (Clinical Laboratory Improvement Amendments) licensed laboratory in Gaithersburg, MD. That laboratory also hosts our Clinical Laboratory Innovation Accelerator, or CLIAx, which we believe is the country’s first shared CLIA laboratory for overseas diagnostics start-ups seeking to launch novel lab tests in the U.S. without the expense of establishing and operating their own, independent lab. As noted above, during the COVID-19 pandemic, we also provided COVID-19 viral testing using polymerase chain reaction, or PCR, analytical equipment in our clinical laboratory. Our legacy business also includes a pioneering field test kit for screening suspicious powders for bioterror agents known as BioCheck. As of the date of this prospectus, we generate revenue from three sources: OneTest for Cancer (primarily as a lab test in the U.S. but we also license our algorithms to overseas labs), BioCheck and from our CLIAx. For each of the nine months ended September 30, 2025 and 2024, sales of OneTest for Cancer accounted for approximately 87% of our revenues, sales of BioCheck accounted for approximately 9% of our revenues, and our CLIAx accounted for approximately 4% of our revenues. For the years ended December 31, 2024 and 2023, sales of OneTest for Cancer accounted for approximately 85% and 65% of our revenues, respectively, sales of BioCheck accounted for approximately 10% and 13% of our revenues, respectively, our CLIAx accounted for approximately 5% and 4% of our revenues, respectively, and COVID-19 testing accounted for approximately 0% and 18% of our revenues, respectively. Our principal executive offices are located in Gaithersburg, MD.
