"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."
