Fourth Quarter 2025 Financial Results
Net revenue in the fourth quarter of 2025 increased 65% to $14.4 million, compared to $8.7 million in the fourth quarter of 2024. The increase was due to an increase in the number of implant systems sold, as well as an increase in the number of new customers.
Gross margin in the fourth quarter of 2025 was 76.7%, compared to 77.6% in the fourth quarter of 2024.

Selling, general, and administrative expenses in the fourth quarter of 2025 increased 79% to $16.3 million, compared to $9.1 million in the fourth quarter of 2024. The increase was primarily due to increased headcount in the commercial organization, higher legal costs related to litigation, higher variable selling expenses, and increased costs associated with becoming a public company.

Research and development expenses in the fourth quarter of 2025 increased 176% to $3.2 million, compared to $1.2 million in the fourth quarter of 2024. The increase was due to investment in new product development efforts, including an initial milestone payment and development related to the robotic platform strategic partnership.

Operating loss in the fourth quarter of 2025 was $8.5 million, compared to a loss of $3.5 million in the fourth quarter of 2024. Net loss in the fourth quarter of 2025 was $7.8 million, compared to a net loss of $3.8 million in the fourth quarter of 2024.

Adjusted EBITDA in the fourth quarter of 2025 was a loss of $7.0 million, compared to a loss of $2.6 million in the fourth quarter of 2024. The increase in loss was primarily due to the aforementioned increased operating expenses.

Full Year 2025 Financial Results
Net revenue in the full year of 2025 increased 50% to $47.3 million, compared to $31.6 million in the full year of 2024. The increase was due to an increase in the number of implant systems sold, as well as an increase in the number of new customers.

Selling, general, and administrative expenses in the full year of 2025 increased 59% to $54.8 million, compared to $34.5 million in the full year of 2024.

Net loss in the full year of 2025 was $40.4 million, compared to a net loss of $15.6 million in the full year of 2024. The increase in operating loss and net loss was primarily related to increased operating expenses and changes in the fair value of the company's preferred stock warrant liability and convertible notes.

Adjusted EBITDA in the full year of 2025 was a loss of $36.1 million, compared to a loss of $11.4 million in the full year of 2024.

Use of Non-GAAP Financial Measures and Key Business Metrics
In addition to our results and measures of performance determined in accordance with U.S. GAAP, we believe that non-GAAP financial measures can be useful in evaluating and comparing our financial and operational performance over multiple periods, identifying trends affecting our business, formulating business plans and making strategic decisions. We use and present Adjusted EBITDA for this purpose. We define Adjusted EBITDA as net loss before interest expense, net, income tax expense, depreciation and amortization, and stock-based compensation expense. We have reconciled our historic non-GAAP financial measures to the applicable most comparable GAAP measures in this press release.

We believe that Adjusted EBITDA, together with a reconciliation to net loss, provides meaningful supplemental information regarding our performance by excluding certain items that may not be indicative of our business, results of operations, or outlook. However, Adjusted EBITDA has limitations as an analytical tool, and you should not consider this measure in isolation or as a substitute for analysis of our financial results as reported under U.S. GAAP. Some of these potential limitations include: (i) other companies, including companies in our industry which have similar business arrangements, may report Adjusted EBITDA, or similarly titled measures but calculate them differently, which reduces their usefulness as comparative measures; (ii) although depreciation and amortization expenses are non-cash charges, the assets being depreciated and amortized may have to be replaced in the future, and Adjusted EBITDA does not reflect cash capital expenditures for such replacements or for new capital expenditure requirements; (iii) Adjusted EBITDA also does not reflect changes in, or cash requirements for, our working capital needs or the potentially dilutive impact of stock-based compensation; and (iv) Adjusted EBITDA does not reflect the interest expense, or the cash requirements necessary to service interest or principal payments, on existing or future debt that we may incur. Because of these and other limitations, you should consider Adjusted EBITDA only as supplemental to other GAAP-based financial measures.

In addition, we believe that the number of implant systems sold is a key business metric and a useful indicator of our ability to drive demand for our implant systems, generate net revenue and expand our business. We regularly review a number of operating and financial metrics to evaluate our business, measure our performance, identify trends affecting our business, formulate our business plan and make strategic decisions.
