**Nyxoah Announces Preliminary Results for the Fourth Quarter and Full Year 2025 and Provides Revenue Guidance for the First Quarter of 2026**

*Strong Start in First Full Quarter of U.S. Commercialization*

**Mont-Saint-Guibert, Belgium – January 12, 2026, 10:05 pm CET / 4:05 pm 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) through neuromodulation, today reported certain preliminary unaudited fourth quarter and full year 2025 financial and operating results.

**Preliminary, Unaudited Fourth Quarter and Full Year 2025 Results**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· For the fourth quarter of 2025, gross revenue is expected to be approximately €6.3 million before
the deferral of approximately €0.6 million due to disposable patches that are to be delivered over time. Net revenue is expected
to be approximately €5.7 million, representing an increase of approximately 348% over revenue of €1.3 million for the fourth
quarter of 2024. U.S. gross revenue for the fourth quarter of 2025 is expected to be approximately €3.9m and net revenue (after deduction
of deferred revenue) is expected to be approximately €3.5 million.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· For the full year 2025, gross revenue is expected to be approximately €11.0 million before the deferral
of approximately €1.0 million due to disposable
patches that are to be delivered over time. Net revenue is expected to be approximately €10.0 million, representing an
increase of approximately 122% over 2024 revenue of €4.5 million. U.S. gross revenue for the full year of 2025 is expected to be
approximately €4.2m and net revenue (after deduction of deferred revenue) is expected to be approximately €3.7 million.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· As of December 31, 2025, the Company has trained 145 surgeons on the Genio system and has activated
57 accounts in the U.S.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· As of December 31, 2025, cash, cash equivalents and financial assets are expected to be approximately
 €47.9 million.

"Our first full quarter of U.S. commercialization post-FDA approval resulted in strong momentum," commented Olivier Taelman, Nyxoah's Chief Executive Officer. "Our first U.S. patients are experiencing great results; we have a waiting list for additional surgeon training and patients scheduled for implants. Global revenue exceeded €10 million due to the strong U.S. launch and further international geographical expansion. We have established a strong foundation for sustained growth and look forward to expanding Genio adoption in the U.S. throughout 2026."

**Revenue Guidance for the First Quarter of 2026**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· We expect U.S. net revenue for the first quarter of 2026 to grow by approximately 25% over the fourth quarter of 2025.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· International revenue is expected to follow a typical seasonal pattern.

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 2025 in its Annual Report on Form 20-F.

Nyxoah is a medical technology company focused on the development and commercialization of innovative solutions to treat OSA.

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 and receipt of approval from the FDA for a subset of adult patients with moderate to severe OSA with an AHI of greater than or equal to 15 and less than or equal to 65.
