European Notified Body approves next-generation manufacturing process that increases production 5-fold, lowers manufacturing costs, improves safety and enables scalable commercial production

GelrinC^®, which is approved for sale in the European Union, is pioneering knee cartilage repair with an off-the-shelf cell-free hydrogel implant

HERZLIYA, IL / ACCESS Newswire / July 15, 2026 / Regentis Biomaterials Ltd. ("Regentis" or the "Company") (NYSE:RGNT), a regenerative medicine company focused on innovative tissue repair solutions, announced today it has received approval from the European Notified Body to manufacture GelrinC^® using its next-generation solvent-free manufacturing process.

The approval comes as Regentis prepares for the commercial launch of GelrinC^® in Europe, enabling the Company to manufacture commercial product using a process that increases production yield by approximately 400%, delivering five times more product from the same manufacturing volume while improving manufacturing efficiency and scalability. The solvent-free process also improves occupational and environmental safety. Extensive clinical testing of the new manufacturing process has validated consistent production quality and clinical performance.

"This approval represents an important commercial milestone for Regentis as we prepare to bring GelrinC^® to orthopedic surgeons across Europe," said Dr. Ehud Geller, CEO and Executive Chairman of Regentis. "Our new manufacturing process substantially improves production efficiency while maintaining the same product quality and clinical performance. Receiving European regulatory approval now allows us to move into commercialization with a manufacturing platform that is substantially more efficient, more scalable and better suited to support long-term global growth."

GelrinC^® is a proprietary, cell-free, ready-to-use hydrogel implant designed to regenerate durable, healthy cartilage through a synchronized erosion process. Unlike cell-based cartilage repair procedures that require tissue harvesting, laboratory processing and multiple surgeries. The 10-minute GelrinC procedure offers a safe and effective alternative to traditional microfracture and complex cell-based therapies addressing a market valued at $3 billion, in the U.S. alone.

The product has already received CE Mark approval in Europe and is being prepared for commercial introduction through Regentis' expanding network of European Centers of Excellence, surgeon training programs and collaborations with leading orthopedic institutions, including Humanitas Research Hospital in Milan.

About GelrinC^®

Regentis' lead product, GelrinC^®, is a cell-free, off-the-shelf hydrogel implant having synchronized erosion and resorption for the treatment of painful and debilitating injuries to focal articular knee cartilage. As an innovative regenerative medical product, GelrinC^® offers an unprecedented solution that gives surgeons and payers an off-the-shelf, ready to use, simple to perform, reliable, and cost-effective procedure that provides patients with a single, 10-minute procedure, faster recovery, sustained pain relief, and functional improvement for more than 5 years, based on clinical study results to date. To the Company's knowledge, there is no effective off-the-shelf, ready to use treatment for focal knee cartilage defects that is currently available on the market. GelrinC^® has CE Mark approval in the European Union and is now being evaluated in a pivotal U.S. Food and Drug Administration (FDA) study, which has completed over 50% enrollment.

About Regentis Biomaterials

Regentis Biomaterials Ltd is a regenerative medicine company dedicated to developing innovative tissue repair solutions that restore health and enhance quality of life. With an initial focus on orthopedic treatments, Regentis' Gelrin platform technology, based on synchronized, degradable hydrogel implants, regenerates damaged or diseased tissue including inflamed cartilage and bone. Regentis' lead product GelrinC^®, is a cell-free, off-the-shelf hydrogel that is eroded and resorbed in the knee, allowing the surrounding cells to regenerate the cartilage in a controlled and synchronous process. GelrinC^® aims to address a market of approximately 470,000 cases for cartilage knee repair annually in the U.S. where no off-the-shelf treatment is available.
