<div id="readability-page-1"><article>Momentum continues to build for Company as series of clinical milestones are met, design choices cement differentiation from competition, and timeline comes into focusWhite Bear Lake, Minnesota--(Newsfile Corp. - December 10, 2025) - Envoy Medical® Inc. (NASDAQ: COCH) (&#34;Envoy Medical&#34; or the &#34;Company&#34;), a hearing health company pioneering fully implanted hearing solutions, today announced the completion of the first set of activations in the final stage of the pivotal clinical study for the investigational fully implanted Acclaim® cochlear implant.These activations were performed at Shohet Ear Associates in Seal Beach, California and the Center for Neurosciences Ear and Hearing Center in Tucson, Arizona, two of the seven investigational sites involved in the study. While specific hearing results from these activations cannot be publicly disclosed until the trial is completed, Envoy Medical notes that no serious adverse events were reported and that the team is pleased with how the activation appointments went.&#34;The steady progress of our pivotal clinical study is exceeding my initial expectations,&#34; said Brent Lucas, Chief Executive Officer of Envoy Medical. &#34;Despite the holiday season and end of year crunch for surgical time, enrollment for the Study is moving along nicely. We continue to be encouraged by the high-level of interest from potential patients and professionals throughout the hearing industry and look forward to successfully completing the trial and preparing for robust commercial demand. &#34;The Acclaim® cochlear implant is an investigational first-of-its-kind cochlear implant designed to leverage the natural ear - not a microphone - to capture sound by using a combination of the Company's proprietary implanted piezoelectric sensor and the body's natural anatomy. Unlike traditional, partially-implanted cochlear implants, the fully implanted Acclaim® cochlear implant does not require a bulky external component to function. In addition, the fully implanted Acclaim® cochlear implant also does not have an implanted magnet to attach external components to the side of the patient's head, as there are no external wearable components required to hear with the Acclaim® device. Moreover, the design of the Acclaim® implant allows for several days approximately four to five days between any required recharging of the battery. The Acclaim® device design also has a removable battery pack that can be replaced by itself without requiring the full system to be explanted.Continued Lucas, &#34;I believe our amazing team has designed a cochlear implant for the future by putting the patient first and foremost with our design choices, and we look forward to bringing those with significant hearing loss a true breakthrough.&#34; Full enrollment of the pivotal trial is expected in early 2026.
