Nyxoah adjusts revenue guidance to €33M–€35M
Nyxoah expects U.S. growth to improve in Q4 2026 compared with Q3 as physicians and centers build experience with Genio.
Sentiment and the balance of points
Rhea-AI Sentiment reads the wording of the document, how positive or negative its language is on a 1 to 5 scale. The balance of points shown with the takes weighs what the document actually discloses, so the two can disagree, for example when a trial that missed its main goal is described in upbeat language.
Rhea-AI Filing Summary
Nyxoah SA adjusted its full-year revenue guidance to €33 to €35 million. The company expects U.S. growth to improve in Q4 compared with Q3 2026 and describes the U.S. sales ramp as more reflective of historical ramps for a new technology as physicians and centers build experience with Genio.
Nyxoah says it sees demand in growing numbers of active accounts and trained U.S. surgeons, and cites positive feedback on Genio. CEO Liam Kelly said the company remains confident in its ability to drive durable U.S. growth. Preliminary, unaudited third-quarter revenue results and cash, cash equivalents and financial assets are estimates subject to revision until Nyxoah reports full third-quarter results.

We continue to expect improving U.S. growth in Q4 compared to Q3 2026. The ramp in U.S. sales is more reflective of historical ramps for a new technology, as physicians and centers build experience with Genio. Our foundations are strong. Physicians and OSA patients want a choice in hypoglossal nerve stimulation therapy. We see this demand in the growing number of active accounts and trained surgeons in the U.S., and in the positive feedback we receive on the Genio system. We remain confident in our ability to drive durable growth in the U.S. and to improve care for OSA patients,” commented Liam Kelly, Nyxoah’s Chief Executive Officer.
The preliminary, unaudited revenue results and cash, cash equivalents and financial assets described in this press release are estimates only and are subject to revision until Nyxoah reports its full financial results for the third quarter of 2026, including in its Quarterly Report on Form 6-K.
About Nyxoah
Nyxoah is a medical technology company focused on the development and commercialization of innovative solutions to treat OSA. Nyxoah’s lead solution is the Genio system, a patient-centered, leadless and battery-free hypoglossal neurostimulation therapy for OSA, the world’s most common sleep disordered breathing condition that is associated with increased mortality risk and cardiovascular comorbidities. Nyxoah is driven by the vision that OSA patients should enjoy restful nights and feel enabled to live their life to its fullest.
Following the successful completion of the BLAST OSA study, the Genio system received its European CE Mark in 2019. Nyxoah completed two successful IPOs: on Euronext Brussels in September 2020 and NASDAQ in July 2021. Following the positive outcomes of the BETTER SLEEP study, Nyxoah received CE mark approval for the expansion of its therapeutic indications to Complete Concentric Collapse (CCC) patients, currently contraindicated in competitors’ therapy. Additionally, the Company announced positive outcomes from the DREAM IDE pivotal study in 2024 and received approval from the FDA in August 2025, with the treatment of CCC patients included in the warning section of our indications for use.
