“Heartflow delivered an outstanding third quarter of 2025,” said John Farquhar, President and CEO of Heartflow. “Durable growth in our FFRCT business and rapid expansion of our installed base drove third quarter total revenue up 41% year-over-year. Physician interest continues to build in Heartflow Plaque Analysis, which increases our confidence in this second wave of growth following broad commercial payor coverage. With continued business momentum and a strengthened balance sheet following our IPO, we believe we are well-positioned to expand our market leadership.”

Total revenue was $46.3 million, a 41% increase year-over-year. U.S. revenue was $42.5 million, a 42% increase year-over-year. International and other revenue was $3.8 million, a 24% increase year-over-year. The year-over-year increase in total global revenue was primarily attributable to an increase in total U.S. FFRCT revenue.

Gross profit was $35.4 million, compared to $24.9 million in the prior year period. Non-GAAP gross profit was $35.5 million, compared to $25.0 million in the prior year period.

Gross margin was 76.5%, compared to 75.7% in the prior year period. Non-GAAP gross margin was 76.8%, compared to 75.9% in the prior year period. The year-over-year gross margin expansion was primarily attributable to an increase in revenue case volume and an increase in production team efficiency.

Total operating expenses were $50.5 million, or 109% of total revenue, compared to $39.9 million, or 121% of total revenue, in the prior year period. Non-GAAP total operating expenses were $46.7 million, or 101% of total revenue, compared to $37.6 million, or 114% of total revenue, in the prior year period. The year-over-year operating expense increase was primarily attributable to increased investment in personnel and related expenses.

Net operating loss was $15.1 million, compared to $14.9 million in the prior year period. Non-GAAP net operating loss was $11.1 million, compared to $12.6 million in the prior year period.

Net loss was $50.9 million, or ($1.04) net loss per share, compared to $19.1 million, or ($3.43) net loss per share, in the prior year period. Net loss for the third quarters of 2025 and 2024 included a noncash charge of $32.1 million and $0.6 million, respectively, resulting from the remeasurement of the fair value of the Company’s common stock warrant liability, with the higher charge in the 2025 period due to the increase in the Company’s stock price following its August 2025 IPO. As of October 22, 2025, the warrant holder has net exercised all warrants in full. Therefore, the fourth quarter of 2025 will be the last quarter that movements in the Company’s stock price will trigger a warrant revaluation and result in a noncash charge to net loss. Net loss for the third quarter of 2025 also included a $4.8 million noncash benefit, resulting from the remeasurement of the fair value of the Company’s derivative liability. The Company continued to record adjustments to the estimated fair value of the derivative liability until the conversion of its convertible notes in connection with its IPO in August 2025. Net loss for the third quarter of 2025 also included a $6.4 million loss on extinguishment of debt, related to the full prepayment of the remaining principal amount of the Company’s term loan in August 2025.

Non-GAAP net loss was $13.2 million, or ($0.27) non-GAAP net loss per share, compared to $16.2 million, or ($2.90) non-GAAP net loss per share, in the prior year period.

Adjusted EBITDA was ($9.8) million for the third quarter of 2025 compared to ($11.2) million for the third quarter of 2024.

Cash and cash equivalents totaled $291.2 million as of September 30, 2025. Subsequent to the IPO, the Company completed a mandatory $55.0 million debt repayment and elected to pay down the remaining principal amount of $60.1 million term loan balance, the impacts of which are reflected in the cash balance as of September 30, 2025.

Heartflow expects total revenue for the full year 2025 to be in the range of $173.0 million to $173.5 million, representing year-over-year growth of approximately 37.5% to 38.0%.

To supplement its consolidated financial statements prepared in accordance with U.S. generally accepted accounting principles (GAAP), the Company discloses non-GAAP gross profit and non-GAAP gross margin, non-GAAP total operating expenses, non-GAAP research and development expense, non-GAAP selling, general and administrative expense, non-GAAP operating loss, non-GAAP net loss, non-GAAP net loss per share, basic and diluted, and adjusted EBITDA (collectively, the “Non-GAAP Measures”) in this press release. As used by the Company, these measures are adjusted to exclude stock-based compensation expense from the comparable GAAP financial measure. Non-GAAP net loss and non-GAAP net loss per share, basic and diluted, are also adjusted for change in fair value of common stock warrant liability, change in fair value of derivative liability and loss on extinguishment of debt. In addition, Adjusted EBITDA is calculated by adding back to net loss or excluding, as appropriate, interest income and expense, provision for income taxes, and charges for depreciation and amortization and is further adjusted by adding back in or excluding, as appropriate, other income and expense items and stock-based compensation. Reconciliations of the Non-GAAP Measures to their most directly comparable GAAP financial measures are provided in the financial statement tables included at the end of this press release, and investors are encouraged to review the reconciliations. The Company believes the presentation of the Non-GAAP Measures, when shown in conjunction with the corresponding GAAP measures, provides useful information to investors as it provides visibility to the Company’s underlying continuing operating performance from period to period by excluding the impact of stock-based compensation. Because of the variety of equity awards used by companies, the varying methodologies for determining stock-based compensation expense, the subjective assumptions used in those determinations, and the volatility in valuations that can be driven by market conditions outside the Company’s control, we believe excluding stock-based compensation expense enhances the ability of management and investors to understand and assess the underlying performance of our business over time and compare it against our peers, a majority of whom also exclude stock-based compensation expense from their non-GAAP results. With respect to the presentation of Adjusted EBITDA, the Company believes it is a useful measure to evaluate the Company’s operating performance and it is used by the Company to evaluate ongoing operations and for planning and forecasting purposes. Adjusted EBITDA is also a measure frequently used by analysts, investors and other interested parties to evaluate companies in our same industry.

The Company’s definition of the Non-GAAP Measures may differ from similarly titled measures used by others. The Non-GAAP Measures should be considered only as a supplement to, and not as a substitute for, or superior to, their most directly comparable GAAP financial measures. Because the Non-GAAP Measures exclude the effect of items that increase or decrease the Company’s reported results of operations, management strongly encourages investors to review the reconciliations to the most comparable GAAP financial measures at the end of this press release and, when they become available, the Company’s consolidated financial statements and publicly filed Securities and Exchange Commission (“SEC”) reports in their entirety.
