Fourth Quarter & Full Year 2025 Financial Results

Revenue was $1.5 million in the fourth quarter of 2025, an increase of 92% compared to $0.8 million in the same period of 2024. Revenue for the year ended December 31, 2025, was $3.9 million, an increase of 20% compared to $3.3 million in the year ended December 31, 2024. The increase in revenue for the year ended December 31, 2025 as compared to 2024 was primarily due to an increase in the number of surgical procedures in the back half of 2025 across both the Catamaran^® and SImmetry^®+ platforms, driven primarily by the adoption of new physician users.

Gross profit was $1.0 million, or 69% of revenue, in the fourth quarter of 2025, compared to $0.4 million, or 46% of revenue, in the fourth quarter of 2024. For the year ended December 31, 2025, gross profit was $2.4 million, or 60% of revenues, compared to $1.7 million, or 52% of revenue, for the year ended December 31, 2024. The eight percentage point gross margin improvement for the year ended December 31, 2025 was primarily driven by higher revenue in the second half of 2025, driving further absorption of fixed costs within cost of goods sold.

Operating expenses totaled $3.9 million in the fourth quarter of 2025, compared to $3.5 million in the fourth quarter of 2024. For the year ended December 31, 2025, operating expenses totaled $15.2 million compared to $15.5 million in the prior year period. The increase in the three months ended December 31, 2025, was primarily due to higher variable expenses within sales and marketing, driven by increased revenue in the period, while the decrease for the year ended December 31, 2025 was due to reduced general and administrative expenses, partially offset by increased sales and marketing investment to support increased sales and continued commercial expansion.

Net loss was $2.8 million, or $0.29 per share, in the fourth quarter of 2025, compared to a net loss of $3.1 million, or $0.98 per share, in the fourth quarter of 2024. For the year ended December 31, 2025, net loss was $12.6 million, or $1.70 per share, compared to a net loss of $13.7 million, or $11.26 per share, in the same year ago period. The year-over-year improvement in both periods was largely driven by increased revenue and reduced operating expenses fortifying operating leverage.

As of December 31, 2025, cash and cash equivalents totaled $3.8 million, compared to $6.5 million at December 31, 2024. The Company had no outstanding debt as of quarter-end, positioning it to continue executing on its strategic initiatives, including the development and launch of the acquired SiVantage assets and expanding the commercial team.
