Nyxoah Reports Third Quarter 2022 Financial and Operating Results

DREAM US pivotal 12-month clinical data expected in fall of 2023

Mont-Saint-Guibert, Belgium – November 8, 2022, 10:05pm CET / 4:05pm ET – Nyxoah SA (Euronext Brussels/Nasdaq: NYXH) (“Nyxoah” or the “Company”), a medical technology company focused on the development and commercialization of innovative solutions to treat Obstructive Sleep Apnea (OSA), today reported financial and operating results for the quarter ended September 30, 2022.

Third Quarter 2022 Financial and Operating Highlights

Completed 110 of 115 implants in the DREAM U.S. pivotal trial to date, with 12-month clinical data expected in the fall of 2023 and regulatory approval in the second quarter of 2024

Activated the first clinical sites in the ACCCESS U.S. pivotal trial to treat complete concentric collapse (CCC) patients in the U.S., with first implants expected in the fourth quarter of 2022

Reported revenue of €182,000 from the commercialization of Genio®; sales during the third quarter were impacted by a temporary inventory shortage in Germany due to a disruption at a component supplier, resulting in unfulfilled third quarter orders of approximately €700,000 in Germany; this supply disruption has subsequently been remedied and the vast majority of the open orders have since been filled

Ended the third quarter with 32 active sites in Germany, up from 26 sites at the end of the second quarter 2022; expects to have up to 40 active sites by the end of 2022

Launched the “Care4” program, using the AcuPebble home sleep test at selected centers of excellence in Germany to accelerate the time from CPAP failure to our Genio solution

Received CE Mark for the next-generation Genio system, Genio 2.1

“With 110 implants in the DREAM trial, we believe we are within weeks of completion of the implants, keeping us on track for 12-month data next fall,” commented Olivier Taelman, Nyxoah’s Chief Executive Officer. “Additionally, ACCCESS, our second US pivotal trial is launched, and first patients are expected to be implanted before year end. This trial is focused on addressing the unmet need of approximately 30% of OSA patients contra-indicated in the U.S. to hypoglossal nerve stimulation due to their complete concentric collapse.”

Mr. Taelman continued, “Commercially in Germany, where we have both CCC and non-CCC indications already, we continue to build on our momentum, as patients and clinicians increasingly recognize the unique benefits of the Genio solution. While third quarter sales reflected a temporary supply disruption, the fourth quarter is off to a strong start, as we are filling both open orders from the third quarter and new ones. This gives us confidence that we can be the German market leader exiting 2022.”

Revenue

Revenue was €182,000 for the third quarter of 2022, compared to €203,000 for the prior year period. The decrease in revenue was attributable to the temporary supply disruption that caused a delay in order fulfillment.

Cost of Goods Sold

Cost of goods sold was €63,000 for the three months ending September 30, 2022, representing a gross profit of €119,000, or gross margin of 65.3%. This compares to total costs of goods sold of €82,000 in the third quarter of 2021, for a gross profit of €121,000, or gross margin of 59.6%.

Research and Development Expenses

Research and development expenses were €4.2 million for the three months ending September 30, 2022, versus €3.5 million for the prior year period, reflecting the Company’s investments in the development of next generation versions of the Genio system as well as ongoing clinical studies, most notably DREAM in the U.S.

Selling, General and Administrative Expenses

General and administrative expenses rose to €4.8 million for the third quarter of 2022, up from €4.5 million in the third quarter of 2021. This was due primarily to increased commercial efforts in Germany and other European markets, as well as investments in Nyxoah’s corporate infrastructure. The Company expects to continue adding headcount across the organization ahead of U.S. commercial launch.

Operating Loss

Total operating loss for the third quarter of 2022 was €8.8 million versus €8.1 million in the third quarter of 2021. This was driven by the delay of third quarter revenue due to the temporary supply disruption, the acceleration in the Company’s R&D spending, and ongoing commercial and clinical activities. Nyxoah realized a net loss of €6.2 million for the third quarter of 2022, compared to a net loss of €8.8 million for the third quarter.

Cash Position

As of September 30, 2022, cash and financial assets totaled €115.4 million, compared to €135.5 million on December 31, 2021. Total cash burn was approximately €3.0 million per month during the third quarter of 2022, and is expected to increase going forward to account for the ACCCESS IDE trial in the U.S.
