Envoy Medical Reports on Second Quarter 2025 Results

Financial and Corporate Highlights for Second Quarter and to date:

• Strong momentum continues in the pivotal clinical trial of its investigational novel hearing device, the fully implanted Acclaim® cochlear implant.
• Successful activation of all 10 study participants' fully implanted Acclaim® cochlear implants in the first stage of the Company's pivotal clinical trial.
• All 10 of the study participants in the first stage of the Company's pivotal clinical trial have successfully completed their one-month follow-up visits. The visits are proceeding as expected and no serious adverse events or unanticipated device events have been reported for any of the 10 participants. The Company anticipates these study participants will complete their three-month follow-up visits in the coming weeks.
• Five Category III CPT codes for totally implantable active middle ear implants, such as the Company's Esteem® device, were approved by the American Medical Association (AMA) Current Procedural Terminology (CPT) Editorial Panel and became effective on July 1, 2025.** The previous lack of CPT codes effectively limited market adoption of and access to these groundbreaking, fully implanted hearing devices. Further changes to reimbursement around the Esteem® device would provide additional business opportunities for the Company.
• Subsequent to the quarter end, two new patents in the US and three new patents in Australia were issued to Envoy Medical, further strengthening its intellectual property portfolio. The Company continues to pursue additional patent protection across the Globe and believes there is strong value in its intellectual portfolio roadmap.

Brent Lucas, CEO of Envoy Medical commented: "This quarter was another win for Envoy Medical as we continue to successfully execute our strategy. We continued to make significant strides with our clinical study as all 10 study participants in the Acclaim® trial were successfully activated and completed their one-month follow-up visits with zero reported serious adverse events or unanticipated device events. We are confident that, once approved, our fully implanted Acclaim® cochlear implant will enjoy substantial patient interest, allowing us a rare opportunity to disrupt an established market and grow into a significant market participant relatively quickly. We believe our investigational fully implanted Acclaim® cochlear implant is well-positioned to be able to capture market share as the industry moves towards fully implanted cochlear implants and away from bulky externals.

As it relates to the Esteem® fully implanted active middle ear implant, which already has FDA approval, we are excited to see the potential for renewed opportunity and possibility. Meaningful changes to reimbursement around this class of hearing devices would provide Envoy Medical with a viable pathway for a product that already has FDA approval, is currently one-of-a-kind in the marketplace, and has demonstrated patient demand. We continue to see wisdom in strategic investments around this product, as a shift in policy or reimbursement could rapidly change Envoy Medical's position in the market.

As we continue to execute our strategy and drive shareholder value, we remain steadfast in our belief that Envoy Medical will be a significant player in the hearing device industry in the near future."

About Envoy Medical, Inc.

Envoy Medical (NASDAQ: COCH) is a hearing health company focused on providing innovative technologies across the hearing loss spectrum. Envoy Medical has pioneered one-of-a-kind, fully implanted devices for hearing loss, including its fully implanted Esteem® active middle ear implant, commercially available in the U.S. since 2010, and the fully implanted Acclaim® cochlear implant, an investigational device. Envoy Medical is dedicated to pushing hearing technology beyond the status quo to improve access, usability, compliance, and ultimately quality of life.

About the Fully Implanted Acclaim® Cochlear Implant

We believe the fully implanted Acclaim Cochlear Implant ("Acclaim CI") is a first-of-its-kind hearing device. Envoy Medical's fully implanted technology includes a sensor designed to leverage the natural anatomy of the ear instead of a microphone to capture sound. The Acclaim CI is designed to address severe to profound sensorineural hearing loss that is not adequately addressed by hearing aids. The Acclaim CI is expected to be indicated for adults who have been deemed adequate candidates by a qualified physician.

The Acclaim Cochlear Implant received the Breakthrough Device Designation from the U.S. Food and Drug Administration (FDA) in 2019.

CAUTION The fully implanted Acclaim Cochlear Implant is an investigational device. Limited by Federal (or United States) law to investigational use.

About the Esteem® Fully Implanted Active Middle Ear Implant (FI-AMEI)

The Esteem fully implanted active middle ear implant (FI-AMEI) is the only FDA-approved, fully implanted* hearing device for adults diagnosed with moderate to severe sensorineural hearing loss allowing for 24/7 hearing capability using the ear's natural anatomy. The Esteem FI-AMEI hearing implant is invisible and requires no externally worn components and nothing is placed in the ear canal for it to function. Unlike hearing aids, you never put it on or take it off. You can't lose it. You don't clean it. The Esteem FI-AMEI hearing implant offers true 24/7 hearing.

*Once activated, the external Esteem FI-AMEI Personal Programmer is not required for daily use.

Important safety information for the Esteem FI-AMEI can be found at: https://www.envoymedical.com/safety-information.
