08:36 AM EDT, 10/07/2025 (MT Newswires) -- Envoy Medical ( COCH ) shares soared 140% in Tuesday's premarket session after the company said it was granted US Food and Drug Administration approval to expand a clinical trial of its fully implanted Acclaim cochlear implant to the final stage.

The company said the approval, which was based on three-month data from the first 10 patients, has shortened its estimated timeline to commercialization by three to six months and has allowed it to reduce its expected capital needs by $10 million to $15 million.
