In brief

What this company does

Our lead solution is the Genio system, a CE-Marked and FDA approved, patient-centric next generation hypoglossal neurostimulation, or HGNS, therapy for the treatment of moderate to severe OSA, implanted via a single-incision procedure. We started generating revenue from the sale of the Genio system in Europe in July 2020. On August 8, 2025, the FDA approved the Genio system for a subset of adult patients with moderate to severe OSA with an Apnea-Hypopnea Index, or AHI, of greater than or equal to 15 and less than or equal to 65, and we started generating revenue from the sale of the Genio system in the U.S. in September 2025.

Written from the business description in Nyxoah SA's annual report to the U.S. Securities and Exchange Commission, filed 26 March 2026. Every sentence was checked against that document before publication.
