About Heart Test Laboratories, Inc.

Laboratories, Inc. (d/b/a HeartSciences) is medical technology company focused on applying innovative AI-based technology to an ECG (also known as an EKG) to expand and improve an ECG s clinical

usefulness. The Company s objective is to make an ECG a far more valuable cardiac screening tool, particularly in frontline or point-of-care clinical settings.

HeartSciences first product candidate for FDA clearance, the MyoVista wavECG, or the MyoVista, is a resting 12-lead ECG that is also designed to provide diagnostic information related to cardiac
