fourth quarter marked our first full quarter of U.S. commercialization, and we are very pleased with the strong momentum we generated
which led to us exceeding our revenue expectations for the quarter," commented Olivier Taelman, Nyxoah's Chief Executive
Officer. "The feedback from surgeons and their patients has been positive and these procedures have been consistently reimbursed
by major commercial payors and Medicare to date. We are excited about the opportunity in front of us and feel confident we will deliver
significant growth going forward."
