Tenon Medical, Inc.

Tenon Medical, Inc. ( we or the Company ) was incorporated in the State of Delaware on June 19, 2012 and was headquartered in San Ramon, California until June 2021 when it relocated to Los Gatos, California. We are a medical device company dedicated to transforming care for patients with certain sacro-pelvic disorders. We currently offer two systems to treat a diseased sacroiliac joint (the SI Joint ). We have developed The Catamaran SI Joint Fusion System ( The Catamaran System ) that offers a novel, less invasive approach to the SI Joint using a single, robust, titanium implant for treatment of the most common types of SI Joint disorders that cause lower back pain. We received U.S. Food and Drug Administration ( FDA ) clearance in 2018 for The Catamaran System and are currently focused on the US market. Since the national launch of The Catamaran System in October 2022, we have been focused on three commercial opportunities: 1) Primary SI Joint procedures, 2) Revision procedures of failed SI Joint implants and 3) SI Joint fusion adjunct to a spine fusion construct. In August 2025, we acquired substantially all of the assets of SiVantage, Inc. and SIMPL Medical, LLC, including the SImmetry + SI Joint Fusion System ( The SImmetry + System ) that treats disorders of the SI Joint through minimally invasive lateral access solution that incorporates well-established orthopedic fusion principles-including joint decortication, bone graft placement, and rigid fixation-with the goal of achieving a true biological fusion across the SI Joint.
