**Envoy Medical Reports Full Year 2025 Financial Results**

 

*Received FDA approval to expand fully implanted Acclaim® Cochlear Implant Pivotal Clinical Trial to final stage*

 

*Strengthened balance sheet by extinguishing $32 million in debt*

 

*Subsequent to year-end, closed on transformational capital raise led by established institutional healthcare investors and completed enrollment of Pivotal Clinical Trial for first-of-its-kind fully implanted cochlear implant*

**White Bear Lake, Minnesota – March 23, 2026** – Envoy Medical® Inc. (NASDAQ: COCH) ("Envoy Medical" or the "Company"), a hearing health company pioneering fully implanted hearing solutions, today announced its corporate and financial results for the full year ended December 31, 2025, as well as other subsequent events.

**Corporate and Financial Highlights for 2025:**

● Received FDA Approval to Expand Its Pivotal Clinical Trial to Final Stage Based on Submission of Promising Three-Month Data

● Extinguished over $32 Million in Debt, Strengthening Balance Sheet

● Completed First Set of Activations in Final Stage of Pivotal Clinical Study for its First-Of-Its-Kind Fully Implanted Acclaim(R) Cochlear Implant

● Achieved Six-Month Milestone with First 10 Patients in Acclaim(R) Cochlear Implant Clinical Trial

**Highlights Subsequent to 2025 Year End:**

● Completed enrollment of a 56-patient U.S. pivotal trial for the fully implanted Acclaim® Cochlear Implant

● Strengthened balance sheet with up to $78M public offering ($30M received, $48M potential from warrants)

● Expanded IP portfolio to 47 patents across North America, Europe, Asia, and Australia as of Feb. 20, 2026

Brent Lucas, CEO of Envoy Medical, commented: "We are extremely proud of the significant progress we made as a company in 2025, which included the FDA approval to expand our pivotal clinical trial to its final stage.

We were also, on the financial side, able to extinguish over $32 million in debt to create a much stronger balance sheet. In addition, we continued to further expand our global patent portfolio as a leading fully implanted hearing technology company.

The momentum from 2025 has set the stage for an exceptional start to 2026. In February, we closed a transformational capital raise that included established institutional healthcare investors and existing shareholders. In March, we announced complete enrollment of our pivotal clinical trial for investigational fully implanted Acclaim cochlear implant. We are now in a strengthened position as we continue to gather data and look forward to submitting our PMA application to the FDA.

The future is bright for Envoy Medical as we aim to revolutionize hearing health by providing fully implanted solutions to address the unmet needs of millions of individuals worldwide. We hope you join us on this meaningful and exciting journey."

**Financial Results for the Year Ended December 31, 2025 (dollars in thousands):**

Net Revenue was $241 as of December 31, 2025 compared to $225 for year ended December 31, 2024. The increase of $16 was primarily driven by the sales of the Esteem® FI-AMEI implant and related replacement components.

Cost of goods sold increased $132 compared to the year ended December 31, 2024. The increase is primarily due to an increase in scrap and non-recurring expenses of $190, which was partially offset by lower fees for third-parties performing work related to our products of $77.

R&D expenses, which include expenses related to the Acclaim pivotal clinical trial, increased by $2,307 for the year ended December 31, 2025 compared to the year ended December 31, 2024. This increase mainly reflects additional clinical trial expense during enrollment.

Sales and marketing expenses of December 31, 2025 were $1,220 compared to $1,734 for the year ended December 31, 2024 a decrease of $514. The decrease is primarily due to a reduction of legal fees associated with reimbursement work for the Esteem FI-AMEI product.

General and administrative expenses increased $1,105 to $7,931 for the year ended December 31, 2025 compared to $6,826 for the year ended December 31, 2024. The increase was primarily due to severance costs associated with the former Chief Financial Officer and increased consulting expenses.

As of December 31, 2025, cash was approximately $3.7 million.

The Acclaim® cochlear implant received Breakthrough Device Designation from the FDA in 2019 and is currently under investigation as part of a U.S. based pivotal clinical trial. For more information on the trial, visit www.envoymedical.com/acclaim-pivotal.

**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.

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

**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.
