Carlsmed® Reports Second Quarter 2025 Financial Results

Q2'25 revenue of $12.1 million, 99% YOY growth

Full year revenue guidance of $45.5M - $47.5M

CARLSBAD, Calif., August 28, 2025 (GLOBE NEWSWIRE) -- Carlsmed, Inc. (Nasdaq: CARL) (“Carlsmed” or the “Company”), a medical technology company pioneering AI-enabled personalized spine surgery solutions, today reported financial results for the second quarter ended June 30, 2025.

“Our strong commercial performance was driven by the continued adoption of our highly differentiated AI-enabled aprevo® technology platform and growing recognition of its ability to deliver more favorable patient outcomes than legacy devices,” said Mike Cordonnier, Chairman and CEO of Carlsmed. “Building upon our momentum in personalized lumbar fusion surgery, in July we successfully completed the first personalized cervical spine surgery using our aprevo® technology platform, launching in 2026. We enter the second half of 2025 well positioned for continued scale as we become the new standard of care in spine fusion surgery.”

Second Quarter Financial Results & Recent Highlights

●

Revenue was $12.1 million for the second quarter of 2025; a 99% increase compared to $6.1 million for the second quarter of 2024. This increase was driven by the increased number of surgical procedures utilizing the aprevo® technology platform in the second quarter of 2025, with average revenue per procedure flat between these periods.

●

Gross profit for the second quarter of 2025 was $8.9 million compared to $4.6 million for the second quarter of 2024, due to our increased revenue. Gross margin was 73.4% for the second quarter of 2025, compared with 75.0% for the second quarter of 2024; this decrease was primarily driven by expedite production fees charged by our contract manufacturer in the second quarter to meet customer timing requirements.

●

Operating expenses were $15.4 million for the second quarter of 2025, compared with $10.9 million for the second quarter of 2024.

Research and development expenses were $4.2 million for the second quarter of 2025, compared with $4.0 million for the second quarter of 2024. This increase was primarily driven by higher personnel costs to support product development and artificial intelligence initiatives, partially offset by lower prototype and materials costs and reduced COMPASS registry costs following enrollment completion in second half of 2024.

Sales and marketing expenses were $7.9 million for the second quarter of 2025, compared with $4.9 million for the second quarter of 2024. This increase was primarily driven by personnel additions and variable sales expenses associated with our revenue growth, as well as an increase in marketing expenses.

General and administrative expenses were $3.3 million for the second quarter of 2025, compared with $2.0 million for the second quarter of 2024. This increase was primarily due to personnel additions to support business growth and costs associated with the transition to being a publicly traded company, including associated legal, accounting, and other professional fees.

●

Net loss was $6.8 million for the second quarter of 2025, compared to a $6.3 million net loss for the second quarter of 2024.

●

Adjusted EBITDA loss was $6.2 million for the second quarters of 2025 and 2024.

●

Cash and cash equivalents were $33.5 million as of June 30, 2025. The Company received $93.5 million of net proceeds, after deducting underwriting discounts and commissions and before other additional offering expenses, from its initial public offering in July 2025.

●

The first personalized cervical spine surgery using the AI-enabled aprevo® technology platform was performed.

●

aprevo® cervical procedures received CMS New Technology Add-On Payment (NTAP) reimbursement, in effect October 1, 2025.

2025 Full Year Financial Outlook

●

Revenue for the full year 2025 is expected to be in the range of $45.5 million to $47.5 million, representing growth of 67% to 75% over 2024.

Non-GAAP Financial Measures

This press release contains certain financial information that is not presented in conformity with U.S. generally accepted accounting principles (“GAAP”), including Adjusted EBITDA. The non-GAAP financial measures are provided as supplemental information to Carlsmed’s financial measures presented in this press release that are calculated and presented in accordance with GAAP.

The Company calculates Adjusted EBITDA as net income (loss), as adjusted to exclude (i) net interest expense and income, (ii) income tax expense (benefit), (iii) depreciation and amortization expense, (iv) stock-based compensation expense and (v) change in fair value of warrant liabilities.

This non-GAAP measure is presented because management believes it allows investors to view the Company’s performance in a manner similar to the method used by management to evaluate financial performance for both strategic and annual operating planning. Management believes that to properly understand short-term and long-term financial trends, it is helpful for investors to understand the impact of the items excluded from the calculation of Adjusted EBITDA, in addition to considering the Company’s GAAP financial measures. The excluded items vary in frequency and/or impact on our results of operations and management believes that the excluded items are not reflective of the Company’s ongoing core business operations and financial condition. Excluding such items allows investors and analysts to compare our operating performance to other companies in our industry and to compare the Company’s period-over-period results.

The non-GAAP financial measures used by Carlsmed may not be the same or calculated in the same manner as those used and calculated by other companies. Non-GAAP financial measures have limitations as analytical tools and should not be considered in isolation or as a substitute for Carlsmed’s financial results prepared and reported in accordance with GAAP. This non-GAAP measure has limitations as an analytical tool and should not be construed as an inference that the Company’s future results will be unaffected by unusual or non-recurring items. We urge investors to review the reconciliation of these non-GAAP financial measures to the comparable GAAP financial measures included in this press release, and not to rely on any single financial measure to evaluate our business. A reconciliation of Adjusted EBITDA reported in this press release to the most comparable GAAP measure for the respective periods appears in the table captioned “Reconciliation of GAAP Net Income (Loss) to Adjusted EBITDA” later in this release. Within the accompanying financial tables presented, certain columns and rows may not add due to the use of rounded numbers.
