EXPLANATORY NOTE

This Registration Statement is filed by Heartflow, Inc., a Delaware corporation (the “Company” or “Registrant”) to register additional securities issuable pursuant to the Heartflow, Inc. 2025 Performance Incentive Plan (the “PIP”) and the Heartflow, Inc. 2025 Employee Stock Purchase Plan (the “ESPP”), and consists of only those items required by General Instruction E to Form S-8.

The PIP includes an evergreen provision, which provides that the total number of shares reserved for issuance under the PIP (the “Share Limit”) will automatically increase if, on the last day of the fiscal year of the Company, the Share Limit has not increased during such fiscal year pursuant to any Board-approved increase(s) by an aggregate amount equal to or greater than five percent (5%) of the total number of shares of the Company’s common stock, par value $0.001 per share (the “Common Stock”), outstanding on the first day of such fiscal year (the “Minimum Annual Increase”), then in an amount equal to the difference between the Minimum Annual Increase and the aggregate amount in which the Share Limit increased pursuant to any Board-approved increase(s) during such fiscal year, effective as of the last day of such fiscal year. Notwithstanding the foregoing, the Company’s Board of Directors may act prior to the last day of such fiscal year to provide that an increase in the Share Limit will be a lesser number of shares of Common Stock than would otherwise occur pursuant to the preceding sentence.

The ESPP also includes an evergreen provision, which provides that the total number of shares reserved for issuance under the ESPP will automatically increase on the first trading day in January of each calendar year during the term of the ESPP by an amount equal to the lesser of (i) one percent (1%) of the total number of shares of Common Stock issued and outstanding on December 31 of the immediately preceding year or (ii) such number of shares of Common Stock as may be established by the Company’s Board of Directors.

Item 4.Description of Securities

Not applicable.

Item 5.Interests of Named Experts and Counsel

The validity of the issuance of Common Stock registered hereby is passed on for the Company by Angela Ahmad. Ms. Ahmad is the Chief Legal & Compliance Officer of the Company and is compensated by the Company as an employee. Ms. Ahmad owns 17,944 shares of Common Stock, 51,518 restricted stock units that are payable in an equivalent number of shares of Common Stock, and Company stock options to acquire up to an additional 379,435 shares of Common Stock. Ms. Ahmad is eligible to receive awards under the PIP and the ESPP.

Item 6.Indemnification of Directors and Officers

Section 145 of the General Corporation Law of the State of Delaware (the “Delaware General Corporation Law”) provides that a corporation may indemnify directors and officers as well as other employees and individuals against expenses (including attorneys’ fees), judgments, fines, and amounts paid in settlement actually and reasonably incurred by such person in connection with any threatened, pending, or completed actions, suits, or proceedings in which such person is made a party by reason of such person being or having been a director, officer, employee, or agent to the Registrant. The Delaware General Corporation Law provides that Section 145 is not exclusive of other rights to which those seeking indemnification may be entitled under any bylaw, agreement, vote of stockholders or disinterested directors, or otherwise. Article VIII of the Registrant’s amended and restated certificate of incorporation provides for indemnification by the Registrant of its directors and officers to the fullest extent permitted by the Delaware General Corporation Law. The Registrant has entered into indemnification agreements with each of its current directors, executive officers, and certain other officers to provide these directors and officers additional contractual assurances regarding the scope of the indemnification set forth in the Registrant’s amended and restated certificate of incorporation and to provide additional procedural protections. There is no pending litigation or proceeding involving a director or executive officer of the Registrant for which indemnification is sought.

Section 102(b)(7) of the Delaware General Corporation Law permits a corporation to provide in its certificate of incorporation that a director or an officer of the corporation shall not be personally liable to the corporation or its stockholders for monetary damages for breach of fiduciary duty as a director or an officer, except for liability (i) for any breach of the director’s or officer’s duty of loyalty to the corporation or its stockholders, (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) in the case of directors, for unlawful payments of dividends or unlawful stock repurchases, redemptions, or other distributions, or (iv) for any transaction from which the director or officer derived an improper personal benefit; provided that officers may not be indemnified for actions by or in the right of the corporation. The Registrant’s amended and restated certificate of incorporation provides for such limitation of liability.

The Registrant maintains standard policies of insurance under which coverage is provided (a) to its directors and officers against loss rising from claims made by reason of breach of duty or other wrongful act and (b) to the Registrant with respect to payments that may be made by the Registrant to such officers and directors pursuant to the above indemnification provision or otherwise as a matter of law.

Item 7.Exemption from Registration Claimed

Not applicable.

Item 8. Exhibits

See the attached Exhibit Index at page 7, which is incorporated herein by reference.

Item 9.Undertakings

(a)The undersigned Registrant hereby undertakes:

(1)To file, during any period in which offers or sales are being made, a post-effective amendment to this Registration Statement:

(i)To include any prospectus required by Section 10(a)(3) of the Securities Act;

(ii)To reflect in the prospectus any facts or events arising after the effective date of this Registration Statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in this Registration Statement;

(iii)To include any material information with respect to the plan of distribution not previously disclosed in this Registration Statement or any material change to such information in this Registration Statement;

provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the Commission by the Registrant pursuant to Section 13 or 15(d) of the Exchange Act that are incorporated by reference in this Registration Statement.

(2)That, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(3)To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

(b)The undersigned Registrant hereby undertakes that, for purposes of determining any liability under the Securities Act, each filing of the Registrant’s annual report pursuant to Section 13(a) or 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Exchange Act) that is incorporated by reference in this Registration Statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(c)Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the Registrant pursuant to the provisions described in Item 6 above, or otherwise, the Registrant has been advised that in the opinion of the Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer or controlling person of the Registrant in the successful defense of any action,

suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.
