Nyxoah Announces Preliminary Results for the Second Quarter of 2026

Nyxoah Announces Preliminary Results for the Second Quarter of 2026
Continued U.S. launch momentum drives second quarter global preliminary net revenue of €7.7 million
CMS proposes 2027 OPPS and ASC payment increase of 12% and 15% respectively

Second Quarter 2026 – Preliminary Sales and Market Metrics
| · | Financials |
| o | Global net revenue is expected to be approximately €7.7 million in the second quarter of 2026, which reflects 21% sequential growth over the first quarter of 2026 | |
| o | U.S. net revenue is expected to be approximately €5.2 million in the second quarter of 2026, which reflects 22% sequential growth over the first quarter of 2026 |
| · | Leading U.S. commercial indicators |
| o | 55 new surgeons trained in Q2, bringing the total to 262 surgeons trained | |
| o | 89 new accounts activated in Q2, bringing the total to 180 active high-volume accounts | |
| o | 427 patients submitted under prior authorization entering Q3 |
| · | Reimbursement US |
| o | CMS is proposing to increase hospital reimbursement for the Genio procedure (C8011) from $31,526 to $35,414, representing an increase of $3,888 (12%) | |
| o | CMS is proposing to increase ASC reimbursement from $27,563 to $31,722, an increase of $4,159 (15%) |

| o | As of June 30, 2026, cash, cash equivalents and financial assets are expected to be approximately €97.8 million |
"We closed Q2 with clear U.S. momentum: the scaling of our U.S. sales force allowed us to double the number of active accounts to 180 high-volume HGNS accounts and deliver a second consecutive quarter of over 20% sequential U.S. revenue growth. Additionally, the recent CMS proposed reimbursement increases in both hospital outpatient and ambulatory surgical centers are among the strongest within APC 5465 (Level 5 Neuromodulation) and, if approved, support continued economic value for the Genio procedure,” commented Olivier Taelman, Nyxoah's Chief Executive Officer. “With $110 million in new financing, the financial overhang is now behind us, and we are positioned to accelerate Genio's U.S commercial ramp and drive toward profitability."
Revenue Guidance for the Full Year 2026
| · | The Company continues to expect global net revenue for the full year 2026 to be in the range of €36 million to €40 million. |
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 second quarter of 2026, including in its Quarterly Report on Form 6-F.
