Nyxoah Announces Preliminary Results for the Second Quarter of 2025

Mont-Saint-Guibert, Belgium – August 11, 2025, 7:00am CET / 1:00am ET – Nyxoah SA (Euronext Brussels/Nasdaq: NYXH) (“Nyxoah” or the “Company”), a medical technology company that develops breakthrough treatment alternatives for Obstructive Sleep Apnea (OSA), today announced certain preliminary, unaudited financial results for the second quarter of 2025 and other business updates.

Preliminary, Unaudited Second Quarter 2025 Financial Results and Business Updates

Announced on August 8, 2025, that the U.S. Food and Drug Administration (FDA) has approved the Genio® system for a subset of adult patients with moderate to severe OSA with an Apnea-Hypopnea Index (AHI) of greater than or equal to 15 and less than or equal to 65. Press Releases | Nyxoah Investors
Revenue for the second quarter of 2025 is anticipated to be approximately €1.3 million, a 73% increase over the second quarter of 2024.
Operating expenses for the second quarter of 2025 are anticipated to be approximately €20.7 million, a 50% increase over the second quarter of 2024.
Cash, cash equivalents and financial assets are anticipated to be approximately €43.0 million at June 30, 2025. The Company also has a term debt facility with €27.5 million of remaining availability which can be drawn down in two equal tranches subject to revenue and other financial milestones.
The Company expects to close patient enrollment in its ACCCESS clinical trial prior to enrolling all 106 potential patients. The study will continue, with the patients currently enrolled, with the co-primary endpoints, Apnea-Hypopnea Index (AHI) and Oxygen Desaturation Index (ODI) responder rates, assessed at 12 months post implant and followed for five years.
The Company reorganized its global R&D function and expects to transition all ongoing R&D activities from Israel to the U.S. and Belgium.
The Company received notice that Inspire Medical Systems, Inc. (“Inspire”) filed a lawsuit against the Company in the United States alleging infringement of certain patents owned by Inspire. The Company is well prepared, has the means and intends to vigorously defend itself in this matter.

“We are pleased with the growth we saw in the second quarter, which provides further evidence that our commercial proof of concept in Germany has been successful,” commented Olivier Taelman, Chief Executive Officer. “With FDA approval in hand, we expect to take the lessons learned from Germany and apply them to the U.S. as we bring our unique Genio system to the U.S. In addition, we believe that the patient population currently enrolled in the ACCCESS study will provide statistically significant results, which along with the outcomes from prior clinical evidence, will provide meaningful data with respect to the safety and efficacy of using Genio therapy in the patient population suffering from Complete Concentric Collapse (“CCC”). Patients with CCC represent a significant unmet need in the treatment of OSA as no FDA approved treatment currently exists.”

The preliminary, unaudited financial results described in this press release, including preliminary revenue and operating expenses for the second quarter of 2025 and preliminary cash, cash equivalents and financial assets as of June 30, 2025, are estimates only. These financial results could change as a result of further review. Accordingly, you should not place undue reliance on this information. Complete financial results for the second quarter of 2025 will be announced and issued on Monday, August 18, 2025 after NASDAQ market close. A webcast of the call will be accessible via the Investor Relations page of the Nyxoah website or through this link: Nyxoah's Q2 2025 Earnings Call Webcast.
