Fourth Quarter and Full Year 2024 Results

Revenue

In the fourth quarter of 2024, the Company began recording a portion of the selling price for a Genio system related to disposable patches as deferred revenue and recognized €0.6 million in the quarter. Due to this deferral, reported revenue was €1.3 million for the fourth quarter ending December 31, 2024, and €4.5 million for the full year. Had the Company not recorded deferred revenue for its disposable patches, total revenue for the fourth quarter would have €1.9 million, up 46% versus the third quarter of 2024. Likewise, revenue for the full year 2024 would have been €5.1 million, up 18% from €4.3 million in 2023. The increase in full year revenue was attributable to the Company's commercialization of the Genio® system, primarily in Germany.

Cost of Goods Sold

Cost of goods sold was €0.3 million for the three months ending December 31, 2024, representing a gross profit of €0.9 million, or gross margin of 73%. This compares to total cost of goods sold of €0.7 million in the fourth quarter of 2023, for a gross profit of €1.1 million, or gross margin of 60%.

For the full year ending December 31, 2024, total cost of goods sold was €1.5 million, representing a gross profit of €3.0 million, or gross margin of 66%. This compares to total cost of goods sold of €1.7 million for the full year of 2023, for a gross profit of €2.7 million, or gross margin of 62%.

Research and Development

For the fourth quarter ending December 31, 2024, research and development expenses were €11.7 million, versus €7.3 million for the fourth quarter ending December 31, 2023. For the full year ending December 31, 2024, research and development expenses were €34.3 million, versus €26.7 million for the full year of 2023. The increase in research and development expenses was primarily driven by higher R&D activities and clinical expenses.

Selling, General and Administrative

For the fourth quarter ending December 31, 2024, selling, general and administrative expenses were €8.1million, versus €4.9 million for the fourth quarter ending December 31, 2023. For the full year ending December 31, 2024, selling, general and administrative expenses were €28.5 million, versus €21.7 million for the full year of 2023. The increase in selling, general and administrative expenses was mainly due to an increase of costs to support the commercialization of Genio® system in Europe and scale up of the Company.

Operating Loss

Total operating loss for the fourth quarter and full year 2024 was €18.3 million and €58.8 million, respectively, versus €10.8 million and €45.1 million in the fourth quarter and full year 2023, respectively. This was driven by the acceleration in the Company's R&D spending, as well as ongoing commercial and clinical activities.

Cash Position

As of December 31, 2024, cash and financial assets totaled €85.6 million, compared to €57.7 million on December 31, 2023.
