(Heartflow) (Nasdaq: HTFL), the leader in AI technology for coronary artery disease (CAD), today reported financial results for the fourth quarter and full year ended December 31, 2025. Fourth Quarter 2025 Highlights Total revenue of $49.1 million, a 40% increase year-over-yearGross margin of 79.5%, non-GAAP gross margin of 79.9%Net operating loss of $17.8 million, non-GAAP net operating loss of $12.5 millionU.S. installed base of 1,465 accounts as of December 31, 2025U.S. Plaque installed base of 489 accounts as of December 31, 2025Aetna began coverage of Heartflow Plaque Analysis, bringing total U.S. covered lives for Plaque to approximately 75% 2026 Annual Guidance Total revenue of $218 million to $222 million (approximately 24% to 26% growth year-over-year)Non-GAAP gross margin of 80% to 81% “Our strong fourth quarter performance concluded a record year for Heartflow,” said John Farquhar, President and CEO of Heartflow. “The accelerating adoption of the Heartflow Platform, combined with our disciplined execution across commercial, innovation, and clinical initiatives, drove 40% fourth quarter and full year revenue growth and record gross margins. We also made significant strides in scaling account activations and driving early physician adoption of Heartflow Plaque Analysis. Our 2026 guidance reflects strong business fundamentals, a solid foundation for growth, and high confidence in consistent execution. With commercial, innovation and clinical catalysts on the horizon, our conviction in the business has never been higher.” Fourth Quarter 2025 Financial ResultsTotal revenue was $49.1 million, a 40% increase year-over-year. U.S. revenue was $44.8 million, a 41% increase year-over-year. International and other revenue was $4.3 million, a 35% increase year-over-year. The year-over-year increase in total global revenue was primarily attributable to an increase in total U.S. FFRCT volume. Gross profit was $39.1 million, compared to $26.3 million in the prior year period. Non-GAAP gross profit was $39.2 million, compared to $26.3 million in the prior year period. Gross margin was 79.5%, compared to 75.0% in the prior year period. Non-GAAP gross margin was 79.9%, compared to 75.3% in the prior year period. The year-over-year gross margin expansion was primarily attributable to an increase in revenue case volume and improved production team productivity driven by AI efficiency initiatives, partially offset by the hiring and training of production team personnel. Total operating expenses were $56.8 million, or 116% of total revenue, compared to $42.3 million, or 121% of total revenue, in the prior year period. Non-GAAP total operating expenses were $51.7 million, or 105% of total revenue, compared to $39.9 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 sales personnel and related expenses, as well as increased investments in technology and clinical research. Net operating loss was $17.8 million, compared to $16.1 million in the prior year period. Non-GAAP net operating loss was $12.5 million, compared to $13.5 million in the prior year period. Net loss was $24.4 million, or ($0.29) net loss per share, compared to $33.0 million, or ($5.59) net loss per share, in the prior year period. Net loss for the fourth quarters of 2025 and 2024 included a noncash charge of $9.3 million and $11.9 million, respectively, resulting from the remeasurement of the fair value of the Company’s common stock warrant liability. As of October 22, 2025, the warrant holder net exercised all warrants in full. Therefore, the fourth quarter of 2025 is 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. Non-GAAP net loss was $9.8 million, or ($0.12) non-GAAP net loss per share, compared to $18.6 million, or ($3.15) non-GAAP net loss per share, in the prior year period. Adjusted EBITDA was ($11.1) million, compared to ($12.0) million in the prior year period. Full Year 2025 Financial ResultsTotal revenue was $176.0 million, a 40% increase year-over-year. U.S. revenue was $160.6 million, a 41% increase year-over-year. International and other revenue was $15.4 million, a 26% increase year-over-year. The year-over-year increase in total global revenue was primarily attributable to an increase in total U.S. FFRCT volume. Gross profit was $135.2 million, compared to $94.4 million in the prior year period. Non-GAAP gross profit was $135.6 million, compared to $94.8 million in the prior year period. Gross margin was 76.8%, compared to 75.1% in the prior year period. Non-GAAP gross margin was 77.0%, compared to 75.3% in the prior year period. The year-over-year gross margin expansion was primarily attributable to an increase in revenue case volume and improved production team productivity driven by AI efficiency initiatives, partially offset by the hiring and training of production team personnel. Total operating expenses were $199.3 million, or 113% of total revenue, compared to $155.7 million, or 124% of total revenue, in the prior year period. Non-GAAP total operating expenses were $185.7 million, or 105% of total revenue, compared to $145.8 million, or 116% 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, as well as increased investments in technology and clinical research. Net operating loss was $64.1 million, compared to $61.2 million in the prior year period. Non-GAAP net operating loss was $50.1 million, compared to $51.0 million in the prior year period. Net loss was $116.8 million, or ($3.17) net loss per share, compared to $96.4 million, or ($17.98) net loss per share, in the prior year period. Non-GAAP net loss was $59.9 million, or ($1.62) non-GAAP net loss per share, compared to $69.6 million, or ($12.98) non-GAAP net loss per share, in the prior year period. Adjusted EBITDA was ($44.7) million, compared to ($45.7) million in the prior year period. Cash, cash equivalents and investments totaled $280.2 million as of December 31, 2025.

Use of Non-GAAP MeasuresTo 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 net 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, stock-based compensation and, as appropriate, other income and expense items that are not reflective of the Company’s underlying continuing operating performance. 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 and certain other items that are not reflective of the Company’s ongoing operations. 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. The Company is not able to provide a reconciliation without unreasonable efforts of its forward-looking guidance related to non-GAAP gross margin to the most directly comparable GAAP financial measure due to the unknown effect of stock-based compensation that is material to the comparable GAAP financial measure.
