**Exhibit 99.1**

**Envoy Medical Reports Landmark Accomplishments, Advancing Toward**

**FDA Approval of First-Of-Its-Kind Fully Implanted Cochlear Implant**

*Company Completes Historic Trial Enrollment, Secures Transformational Financing, and*

*Sees Promising Early Clinical Data Presented at Industry Conferences* 

**White Bear Lake, Minnesota – May 11, 2026** – Envoy Medical<sup>®</sup> Inc. (NASDAQ: COCH) ("Envoy Medical" or the "Company"), a hearing health company pioneering fully implanted hearing solutions, today reported first quarter 2026 results and landmark achievements that advance the Company another step closer toward commercialization of its investigational Acclaim<sup>®</sup> cochlear implant.

"The first quarter of 2026 marked a transformative period for Envoy Medical, highlighted by the completion of enrollment in our pivotal clinical trial and the successful execution of a significant financing," said Brent Lucas, Chief Executive Officer of Envoy Medical. "Achieving full enrollment in our pivotal clinical study represents a critical step. We continue to be encouraged by the trial's progress and remain focused on advancing toward PMA submission and, ultimately, commercialization. With a substantially strengthened balance sheet and the support of leading healthcare investors, we believe we are well positioned to execute on our strategic objectives and deliver on the roadmap ahead."

**Corporate and Financial Highlights for Q1 2026:**

● Pivotal Trial Enrollment Complete — A First for the Industry

In a defining milestone for the hearing health sector, Envoy Medical became the first cochlear implant company to achieve full enrollment of a U.S. pivotal clinical trial evaluating a fully implanted cochlear implant seeking FDA approval. The 56th and final patient was successfully implanted on March 11, 2026, completing enrollment across U.S. sites. The Company is now collecting 12-month follow-up data from all participants, with a Premarket Approval (PMA) submission to the FDA to follow.

● Transformational Capital Raise

Envoy Medical closed an upsized public offering for up to $78.0 million, including $30.0 million in gross proceeds at closing with up to an additional $48.0 million of potential aggregate gross proceeds upon the exercise in full of milestone-linked warrants. The financing was led by Nantahala Capital and included healthcare-dedicated funds such as Broadfin Holdings, as well as existing shareholders including members of the Board and management team.

● Expanded Intellectual Property Portfolio

As of February 20, 2026, Envoy Medical has expanded its global IP portfolio to 47 patents across North America, Europe, Asia, and Australia. In February alone, the Company secured three new patents strengthening its competitive position in the fully implanted hearing space.

**Highlights Subsequent to Q1 2026:**

● Promising Early Clinical Data Presented

Interim six-month clinical data from the first 10 patients in the pivotal study showed no study-defined serious adverse events, mean CNC word recognition improved from 15.2% to 39.2%, median daily device wear time of 24 hours, and improvements in quality-of-life and tinnitus scores. Initial safety and performance data for these 10 patients were presented at the American Academy of Audiology Annual Conference and the Combined Otolaryngology Spring Meetings.

● All 56 Pivotal Trial Patients Activated

Following the completion of enrollment, Envoy Medical confirmed that all 56 patients implanted in the pivotal clinical trial have been activated. This milestone validates that the full patient cohort is progressing through the study protocol on schedule, keeping the Company on track to collect the 12-month endpoint data required for its planned PMA submission to the FDA.

● Board Strengthened

Envoy Medical appointed medical device veteran Chas McKhann to its Board of Directors in April 2026, further enhancing the Company's expertise as it prepares to conclude its pivotal clinical study and prepare for commercial launch.

● First Patients Reach 12-Month Endpoint

The first three patients implanted in the pivotal trial successfully completed their 12-month endpoint visit, marking a key milestone in the study's progress. The primary endpoints for the trial are tied to 12-month data, and achieving this critical milestone on schedule underscores the Company's continued execution as it steadily marches toward PMA submission and commercialization.

**Financial Results for the Quarter Ended March 31, 2026 (dollars in thousands):**

Net Revenue was $39 for the three months ended March 31, 2026.

Cost of goods sold for the three months ended March 31, 2026, were $313, compared to $226. The $87 increase is primarily due to higher scrap and materials usage as well as increased fees for third-parties performing work related to our products.

R&D expenses for the three months ended March 31, 2026, were $3,642 compared to $2,748 for the three months ended March 31, 2025. This increase of $894 mainly reflects additional clinical trial activity and related personnel costs during enrollment.

Sales and marketing expenses for the three months ended March 31, 2026, were $164 compared to $358 for the three months ended March 31, 2025. The decrease of $194 is primarily due to the reallocation of resources to research and development activities in support of the clinical trial.

General and administrative expenses are $1,879 for the three months ended March 31, 2026, compared to $1,821 for the three months ended March 31, 2025. The increase of $58 was primarily due to higher investor relations and legal expenses.

As of March 31, 2026, cash was approximately $25,251.

The Acclaim<sup>®</sup> 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<sup>®</sup> 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<sup>®</sup> 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.
