Nyxoah Appoints Liam Kelly as Chief Executive Officer
Further strengthening the Company’s strategic U.S. presence and focus
Mont-Saint-Guibert, Belgium – September 28, 2026, 10:30 pm CET / 4:30 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 announced the appointment of Liam Kelly as Chief Executive Officer, effective October 1, 2026, succeeding Olivier Taelman.
The appointment reflects Nyxoah’s continued evolution into a U.S.-focused commercial organization following FDA approval and the launch of Genio in the United States.
Liam Kelly brings more than 25 years of leadership experience. He served as Chairman, President and Chief Executive Officer of Teleflex Incorporated (NYSE: TFX), a global provider of medical technology products, until January 2026. He led Teleflex as President and Chief Executive Officer from January 2018 and as Chairman of the Board from May 2020. Mr. Kelly joined Teleflex in 2009 and held a series of senior operating roles, including President of EMEA, President, International, President, Americas, and Chief Operating Officer. Before Teleflex, he spent ten years at Hill-Rom Holdings, Inc. in senior management roles. Mr. Kelly is a director of Enovis Corporation (NYSE: ENOV) and holds a Bachelor of Business Studies from the University of Limerick.
“Nyxoah is entering a new chapter, with the United States at the center of our growth strategy. We are very pleased to welcome Liam as our new CEO. He is a seasoned U.S. MedTech executive with a strong track record of scaling organizations, driving commercial performance and creating shareholder value,” said Robert Taub, Chairman of Nyxoah. “On behalf of the Board, I also want to thank Olivier for his leadership over the past seven years and his contribution in bringing Nyxoah from clinical development through FDA approval and into U.S. commercialization.”
“I am incredibly excited to join Nyxoah at this pivotal stage,” said Liam Kelly. “Genio is a truly differentiated technology in the treatment of sleep apnea. The technology has tremendous potential to impact patient lives globally. The U.S. launch is still in its early stages, and the momentum we’re seeing in physician adoption gives me great confidence in what lies ahead. Drawing on my experience at Teleflex building and scaling global businesses, I look forward to working with the Nyxoah team to scale the business and bring Genio to many more OSA patients.”
About Nyxoah
