Equity Offering

On April 14, 2026, Revolution Medicines, Inc. (the “Company”) entered into an underwriting agreement (the “Equity Underwriting Agreement”) with J.P. Morgan Securities LLC, TD Securities (USA) LLC and Guggenheim Securities, LLC, as representatives of the several underwriters named therein (collectively, the “Equity Underwriters”), to issue and sell 10,563,381 shares of the Company’s common stock, $0.0001 par value per share (“Common Stock”), at a public offering price of $142.00 per share (the “Equity Offering”).

In addition, the Company granted the Equity Underwriters a 30-day option to purchase up to an additional 1,584,506 shares of Common Stock, on the same terms and conditions, which the Equity Underwriters exercised in full on April 15, 2026. The net proceeds from the Equity Offering are expected to be approximately $1,650.4 million, after deducting the underwriting discounts and commissions and estimated offering expenses payable by the Company.

The shares of Common Stock described above were offered pursuant to an automatic shelf registration statement (File No. 333-277640) filed with the U.S. Securities and Exchange Commission (the “SEC”) on March 4, 2024. A final prospectus supplement dated April 14, 2026 relating to and describing the terms of the Equity Offering was filed with the SEC on April 15, 2026. The Equity Offering closed on April 16, 2026.

The Equity Underwriting Agreement contains customary representations, warranties and covenants. In the Equity Underwriting Agreement, the Company has also agreed to indemnify the Equity Underwriters against certain liabilities, including liabilities under the Securities Act of 1933, as amended, or to contribute payments that the Equity Underwriters may be required to make because of such liabilities.

A copy of the Equity Underwriting Agreement is filed as Exhibit 1.1 and is incorporated herein by reference. The foregoing description of the Equity Underwriting Agreement does not purport to be complete and is qualified in its entirety by reference to such exhibit.

A copy of the opinion of Latham & Watkins LLP relating to the validity of the issuance and sale of the shares of Common Stock in the Equity Offering is filed herewith as Exhibit 5.1.

Convertible Note Offering

Concurrently with the Equity Offering, on April 14, 2026, the Company entered into a separate underwriting agreement with J.P. Morgan Securities LLC, TD Securities (USA) LLC and Guggenheim Securities, LLC, as representatives of the several underwriters named therein, relating to the offer and sale of $500,000,000 aggregate principal amount of the Company’s 0.50% Convertible Senior Notes due 2033 (the “Convertible Note Offering”). The Convertible Note Offering is expected to close on April 17, 2026, subject to customary closing conditions.

Revolution

Medicines, Inc., a Delaware corporation (the “Company”), proposes to issue and sell to the several underwriters listed in Schedule 1 hereto (the “Underwriters”), for whom you are acting as

representatives (the “Representatives”), an aggregate of 10,563,381 shares of common stock, par value $0.0001 per share (the “Common Stock”), of the Company (the “Underwritten

Shares”) and, at the option of the Underwriters, up to an additional 1,584,506 shares of Common Stock of the Company (the “Option Shares”). The Underwritten Shares and the Option Shares are herein referred to

as the “Shares”. The shares of Common Stock of the Company to be outstanding after giving effect to the sale of the Shares are referred to herein as the “Stock”.

Substantially concurrently with the offering of the Shares, the Company will, among other things, issue and sell $500,000,000 aggregate

principal amount of its 0.50% Convertible Senior Notes due 2033 (the “Convertible Notes”), pursuant to a separate underwriting agreement and separate prospectus supplement (such offering, the “Concurrent

Offering”). The offering of the Shares is not contingent upon the completion of the Concurrent Offering, the Concurrent Offering is not contingent upon the completion of the offering of the Shares, and the Shares are not being offered

together with the Convertible Notes.

The Company hereby confirms its agreement with the several Underwriters concerning the

purchase and sale of the Shares, as follows:

1. Registration Statement. The Company has prepared and filed with the Securities and

Exchange Commission (the “Commission”) under the Securities Act of 1933, as amended, and the rules and regulations of the Commission thereunder (collectively, the “Securities Act”), a registration

statement on Form S-3 (File No. 333-277640), including a prospectus, relating to certain securities, including the Common Stock, to be issued from time to time by

the Company. Such registration statement and any post-effective amendment thereto, as amended at the time it became effective, including the information, if any, deemed pursuant to Rule 430A, 430B or 430C under the Securities Act to be part of the

registration statement at the time of its effectiveness (“Rule 430 Information”), is referred to herein as the “Registration Statement”; and as used herein, the term “Preliminary

Prospectus” means each prospectus included in such registration statement (and any amendments thereto) before effectiveness, any prospectus filed with the Commission pursuant to Rule 424(a) under the Securities Act and the prospectus

included in the Registration Statement at the time of its effectiveness that omits Rule 430 Information, and the term “Prospectus” means the prospectus in the form first used (or made available upon request of purchasers

pursuant to Rule 173 under the Securities Act) in connection with confirmation of sales of the Shares. If the Company has filed an abbreviated registration statement pursuant to Rule 462(b) under the Securities Act (the “Rule 462

Registration Statement”), then any reference herein to the term “Registration Statement” shall be deemed to include such Rule 462 Registration Statement. Any reference in this underwriting agreement (this

“Agreement”) to the Registration Statement, any Preliminary Prospectus or the Prospectus shall be deemed to refer to and include the documents incorporated by reference therein pursuant to Item 12 of Form S-3 under the Securities Act, as of the effective date of the Registration Statement or the date of such Preliminary Prospectus or the Prospectus, as the case may be, and any reference to “amend”,

“amendment” or “supplement” with respect to the Registration Statement, any Preliminary Prospectus or the Prospectus shall be deemed to refer to and include any documents filed after such date under the Securities Exchange

Act of 1934, as amended, and the rules and regulations of the Commission thereunder (collectively, the “Exchange Act”), that are deemed to be incorporated by reference therein. Capitalized terms used but not defined herein

shall have the meanings given to such terms in the Registration Statement and the Prospectus.

At or prior to the Applicable Time (as

defined below), the Company had prepared the following information (collectively with the pricing information set forth on Annex A, the “Pricing Disclosure Package”): a Preliminary Prospectus dated April 13, 2026 and

each “free writing prospectus” (as defined pursuant to Rule 405 under the Securities Act) listed on Annex A hereto.

“Applicable Time” means 6:30 P.M., New York City time, on April 14, 2026.

2. Purchase of the Shares.

(a) The Company agrees to issue and sell the Underwritten Shares to the several Underwriters as provided in this Agreement, and

each Underwriter, on the basis of the representations, warranties and agreements set forth herein and subject to the conditions set forth herein, agrees, severally and not jointly, to purchase at a price per share of $135.965 (the

“Purchase Price”) from the Company the respective number of Underwritten Shares set forth opposite such Underwriter’s name in Schedule 1 hereto.

In addition, the Company agrees to issue and sell the Option Shares to the several Underwriters as provided in this Agreement,

and the Underwriters, on the basis of the representations, warranties and agreements set forth herein and subject to the conditions set forth herein, shall have the option to purchase, severally and not jointly, from the Company the Option Shares at

the Purchase Price less an amount per share equal to any dividends or distributions declared by the Company and payable on the Underwritten Shares but not payable on the Option Shares. If any Option Shares are to be purchased, the number of Option

Shares to be purchased by each Underwriter shall be the number of Option Shares which bears the same ratio to the aggregate number of Option Shares being purchased as the number of Underwritten Shares set forth opposite the name of such Underwriter

in Schedule 1 hereto (or such number increased as set forth in Section 10 hereof) bears to the aggregate number of Underwritten Shares being purchased from the Company by the several Underwriters, subject, however, to such adjustments to

eliminate any fractional Shares as the Representatives in their sole discretion shall make.

The Underwriters may exercise

the option to purchase Option Shares at any time in whole, or from time to time in part, on or before the thirtieth (30th) day following the date of the Prospectus, by written notice from the Representatives to the Company. Such notice shall set

forth the aggregate number of Option Shares as to which the option is being exercised and the date and time when the Option Shares are to be delivered and paid for, which may be the same date and time as the Closing Date (as hereinafter defined) but

shall not be earlier than the Closing Date nor later than the tenth full business day (as hereinafter defined) after the date of such notice (unless such time and date are postponed in accordance with the provisions of Section 10 hereof). Any

such notice shall be given at least one business day prior to the date and time of delivery specified therein.

(b) The

Company understands that the Underwriters intend to make a public offering of the Shares, and initially to offer the Shares on the terms set forth in the Pricing Disclosure Package. The Company acknowledges and agrees that the Underwriters may offer

and sell Shares to or through any affiliate of an Underwriter.

(c) Payment for the Shares shall be made by wire transfer

in immediately available funds to the account specified by the Company to the Representatives in the case of the Underwritten Shares, at the offices of Davis Polk & Wardwell LLP, 900 Middlefield Road, Redwood City, California 94063 at 10:00

A.M., New York City time, on April 16, 2026, or at such other time or place on the same or such other date,

-3-

not later than the fifth business day thereafter, as the Representatives and the Company may agree upon in writing or, in the case of the Option Shares, on the date and at the time and place

specified by the Representatives in the written notice of the Underwriters’ election to purchase such Option Shares. The time and date of such payment for the Underwritten Shares is referred to herein as the “Closing

Date,” and the time and date for such payment for the Option Shares, if other than the Closing Date, is herein referred to as the “Additional Closing Date”.

Payment for the Shares to be purchased on the Closing Date or the Additional Closing Date, as the case may be, shall be made

against delivery to the Representatives for the respective accounts of the several Underwriters of the Shares to be purchased on the Closing Date or the Additional Closing Date, as the case may be, with any transfer taxes or other similar taxes

payable in connection with the sale of such Shares to the Underwriters duly paid by the Company. Delivery of the Shares shall be made through the facilities of The Depository Trust Company unless the Representatives shall otherwise instruct.

(d) The Company acknowledges and agrees that the Representatives and the other Underwriters are acting solely in the capacity

of an arm’s length contractual counterparty to the Company with respect to the offering of Shares contemplated hereby (including in connection with determining the terms of the offering) and not as a financial advisor or a fiduciary to, or an

agent of, the Company or any other person. Additionally, neither the Representatives nor the other Underwriters is advising the Company or any other person as to any legal, tax, investment, accounting or regulatory matters in any jurisdiction. The

Company shall consult with its own advisors concerning such matters and shall be responsible for making its own independent investigation and appraisal of the transactions contemplated hereby, and neither the Representatives nor the other

Underwriters shall have any responsibility or liability to the Company with respect thereto. Any review by the Representatives and the other Underwriters of the Company, the transactions contemplated hereby or other matters relating to such

transactions will be performed solely for the benefit of the Representatives and the other Underwriters and shall not be on behalf of the Company.

of their respective businesses requires such qualification, and have all power and authority necessary to own or hold their respective properties and to conduct the businesses in which they are engaged, except where the failure to be so qualified or

Securities Act. The Company has paid the registration fee for this offering pursuant to Rule 456(b)(1) under the Securities Act or will pay such fee within the time period required by such rule (without giving effect to the proviso therein) and in

any event prior to the Closing Date.

(ww) No Ratings. There are (and prior to the Closing Date, will be) no debt

securities, convertible securities or preferred stock issued or guaranteed by the Company or any of its subsidiaries that are rated by a “nationally recognized statistical rating organization”, as such term is defined in

Section 3(a)(62) under the Exchange Act.

(xx) Outbound Investments. Neither the Company nor any of its

subsidiaries is a “covered foreign person” as that term is used in the Outbound Investment Rules. Neither the Company nor any of its subsidiaries currently engages, or has any present intention to engage in the future, directly or

indirectly, in (i) a “covered activity” or a “covered transaction”, as each such term is defined in the Outbound Investment Rules, (ii) any activity or transaction that would constitute a “covered

activity” or a “covered transaction”, as each such term is defined in the Outbound Investment Rules, if the Company were a U.S. Person or (iii) any other activity that would cause the Underwriters to be in violation of the

Outbound Investment Rules or cause the Underwriters to be legally prohibited by the Outbound Investment Rules from performing under this Agreement. For the purpose of this Agreement, “Outbound Investment Rules” means the regulations

administered and enforced, together with any related public guidance issued, by the United States Treasury Department under U.S. Executive Order 14105 of August 9, 2023, or any similar law or regulation as of the date of this Agreement, and as

codified at 31 C.F.R. Part 850.

copies of the Prospectus (including all amendments and supplements thereto and documents incorporated by reference therein and each Issuer Free Writing Prospectus) as the Representatives may reasonably request. As used herein, the term

delivered (or required to be delivered but for Rule 172 under the Securities Act) in connection with sales of the Shares by any Underwriter or dealer.

(c) Amendments or Supplements, Issuer Free Writing Prospectuses. Before making, preparing, using, authorizing,

approving, referring to or filing any Issuer Free Writing Prospectus, and before filing any amendment or supplement to the Registration Statement, the Pricing Disclosure Package or the Prospectus, the Company will furnish to the Representatives and

counsel for the Underwriters a copy of the proposed Issuer Free Writing Prospectus, amendment or supplement for review and will not make, prepare, use, authorize, approve, refer to or file any such Issuer Free Writing Prospectus or file any such

(vii) of the receipt by the Company of any notice of objection of the Commission to the use of the Registration Statement or any post-effective amendment thereto pursuant to Rule 401(g)(2) under the Securities Act; and (viii) of the

receipt by the Company of any notice with respect to any suspension of the qualification of the Shares for offer and sale in any jurisdiction or the initiation or, to the knowledge of the Company, threatening of any proceeding for such purpose; and

the Company will use its reasonable best efforts to prevent the issuance of any such order suspending the effectiveness of the Registration Statement, preventing or suspending the use of any Preliminary Prospectus, the Pricing Disclosure Package or

the Prospectus or suspending any such qualification of the Shares and, if any such order is issued, will obtain as soon as possible the withdrawal thereof.

(e) Ongoing Compliance. (1) If during the Prospectus Delivery Period (i) any event or development shall occur

and forthwith prepare and, subject to paragraph (c) above, file with the Commission and furnish to the Underwriters and to such dealers as the Representatives may designate such amendments or supplements to the Prospectus (or any document to

-22-

be filed with the Commission and incorporated by reference therein) as may be necessary so that the statements in the Prospectus as so amended or supplemented (or any document to be filed with

the Commission and incorporated by reference therein) will not, in the light of the circumstances existing when the Prospectus is delivered to a purchaser, be misleading or so that the Prospectus will comply with applicable law and (2) if at

any time prior to the Closing Date or any Additional Closing Date, as the case may be, (i) any event or development shall occur or condition shall exist as a result of which the Pricing Disclosure Package as then amended or supplemented would

include any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in the light of the circumstances existing when the Pricing Disclosure Package is delivered to a purchaser, not

misleading or (ii) it is necessary to amend or supplement the Pricing Disclosure Package to comply with applicable law, the Company will promptly notify the Underwriters thereof and forthwith prepare and, subject to paragraph (c) above,

file with the Commission (to the extent required) and furnish to the Underwriters and to such dealers as the Representatives may designate, such amendments or supplements to the Pricing Disclosure Package (or any document to be filed with the

Commission and incorporated by reference therein) as may be necessary so that the statements in the Pricing Disclosure Package as so amended or supplemented will not, in the light of the circumstances existing when the Pricing Disclosure Package is

delivered to a purchaser, be misleading or so that the Pricing Disclosure Package will comply with applicable law.

7. Indemnification

and Contribution.

(a) Indemnification of the Underwriters. The Company agrees to indemnify and hold harmless each Underwriter,

its affiliates, employees, agents, directors and officers and each person, if any, who controls such Underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, from and against any and all losses,

claims, damages and liabilities (including, without limitation, legal fees and other expenses incurred in connection with any suit, action or proceeding or any claim asserted, as such fees and expenses are incurred), joint or several, that arise out

of, or are based upon, (i) any untrue statement or alleged untrue statement of a material fact contained or incorporated by reference in the Registration Statement or caused by any omission or alleged omission to state therein a material fact

required to be stated therein or necessary in order to make the statements therein, not misleading, or (ii) any untrue statement or alleged untrue statement of a material fact contained or incorporated by reference in the Prospectus (or any

amendment or supplement thereto), any Preliminary Prospectus, any Issuer Free Writing Prospectus, any “issuer information” filed or required to be filed pursuant to Rule 433(d) under the Securities Act, any road show as defined in Rule

433(h) under the Securities Act (a “road show”) or any Pricing Disclosure Package (including any Pricing Disclosure Package that has subsequently been amended), or caused by any omission or alleged omission to state therein

a material fact necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading, in each case except insofar as such losses, claims, damages or liabilities arise out of, or are based upon,

any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with any information relating to any Underwriter furnished to the Company in writing by such Underwriter through the Representatives

expressly for use therein, it being understood and agreed that the only such information furnished by any Underwriter consists of the information described as such in paragraph (b) below.

-28-

(b) Indemnification of the Company. Each Underwriter agrees, severally and not

jointly, to indemnify and hold harmless the Company, its directors, its officers who signed the Registration Statement and each person, if any, who controls the Company within the meaning of Section 15 of the Securities Act or Section 20

of the Exchange Act to the same extent as the indemnity set forth in paragraph (a) above, but only with respect to any losses, claims, damages or liabilities (including, without limitation, legal fees and other expenses incurred in connection

with any suit, action or proceeding or any claim asserted, as such fees and expenses are incurred) that arise out of, or are based upon, any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity

with any information relating to such Underwriter furnished to the Company in writing by such Underwriter through the Representatives expressly for use in the Registration Statement, the Prospectus (or any amendment or supplement thereto), any

Preliminary Prospectus, any Issuer Free Writing Prospectus, any road show or any Pricing Disclosure Package (including any Pricing Disclosure Package that has subsequently been amended), it being understood and agreed upon that the only such

information furnished by any Underwriter consists of the following information in the Prospectus furnished on behalf of each Underwriter: the concession figures appearing in the fourth paragraph under the caption “Underwriting” and the

information contained in the fifteenth and sixteenth paragraphs under the caption “Underwriting” relating to price stabilization, short positions and penalty bids.

(c) Notice and Procedures. If any suit, action, proceeding (including any governmental or regulatory investigation), claim or demand

shall be brought or asserted against any person in respect of which indemnification may be sought pursuant to the preceding paragraphs of this Section 7, such person (the “Indemnified Person”) shall promptly notify the

person against whom such indemnification may be sought (the “Indemnifying Person”) in writing; provided, that the failure to notify the Indemnifying Person shall not relieve it from any liability that it may have

under the preceding paragraphs of this Section 7 except to the extent that it has been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure; and provided, further, that the failure to notify

the Indemnifying Person shall not relieve it from any liability that it may have to an Indemnified Person otherwise than under the preceding paragraphs of this Section 7. If any such proceeding shall be brought or asserted against an

Indemnified Person and it shall have notified the Indemnifying Person thereof, the Indemnifying Person shall retain counsel reasonably satisfactory to the Indemnified Person (who shall not, without the consent of the Indemnified Person, be counsel

to the Indemnifying Person) to represent the Indemnified Person and any others entitled to indemnification pursuant to this Section that the Indemnifying Person may designate in such proceeding and shall pay the reasonable fees and expenses of such

counsel related to such proceeding, as incurred. In any such proceeding, any Indemnified Person shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such Indemnified Person unless

(i) the Indemnifying Person and the Indemnified Person shall have mutually agreed to the contrary; (ii) the Indemnifying Person has failed within a reasonable time to retain counsel reasonably satisfactory to the Indemnified Person;

(iii) the Indemnified Person shall have reasonably concluded that there may be legal defenses available to it that are different from or in addition to those available to the Indemnifying Person; or (iv) the named parties in any such

proceeding (including any impleaded parties) include both the Indemnifying Person and the Indemnified Person and representation of both parties by the same counsel would be inappropriate due to

-29-

actual or potential differing interests between them. It is understood and agreed that the Indemnifying Person shall not, in connection with any proceeding or related proceeding in the same

jurisdiction, be liable for the fees and expenses of more than one separate firm (in addition to any local counsel) for all Indemnified Persons, and that all such fees and expenses shall be paid or reimbursed as they are incurred. Any such separate

firm for any Underwriter, its affiliates, directors and officers and any control persons of such Underwriter shall be designated in writing by the Representatives and any such separate firm for the Company, its directors, its officers who signed the

Registration Statement and any control persons of the Company shall be designated in writing by the Company. The Indemnifying Person shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with

such consent, the Indemnifying Person agrees to indemnify each Indemnified Person from and against any loss or liability by reason of such settlement. Notwithstanding the foregoing sentence, if at any time an Indemnified Person shall have requested

that an Indemnifying Person reimburse the Indemnified Person for fees and expenses of counsel as contemplated by this paragraph, the Indemnifying Person shall be liable for any settlement of any proceeding effected without its written consent if

(i) such settlement is entered into more than 30 days after receipt by the Indemnifying Person of such request and (ii) the Indemnifying Person shall not have reimbursed the Indemnified Person in accordance with such request prior to the

date of such settlement. No Indemnifying Person shall, without the written consent of the Indemnified Person, effect any settlement of any pending or threatened proceeding in respect of which any Indemnified Person is or could have been a party and

indemnification could have been sought hereunder by such Indemnified Person, unless such settlement (x) includes an unconditional release of such Indemnified Person, in form and substance reasonably satisfactory to such Indemnified Person, from

all liability on claims that are the subject matter of such proceeding and (y) does not include any statement as to or any admission of fault, culpability or a failure to act by or on behalf of any Indemnified Person.

(d) Contribution. If the indemnification provided for in paragraphs (a) or (b) above is unavailable to an Indemnified Person or

insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each Indemnifying Person under such paragraph, in lieu of indemnifying such Indemnified Person thereunder, shall contribute to the amount paid or payable

by such Indemnified Person as a result of such losses, claims, damages or liabilities (i) in such proportion as is appropriate to reflect the relative benefits received by the Company, on the one hand, and the Underwriters on the other, from

the offering of the Shares or (ii) if the allocation provided by clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) but also the

relative fault of the Company, on the one hand, and the Underwriters on the other, in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations.

The relative benefits received by the Company, on the one hand, and the Underwriters on the other, shall be deemed to be in the same respective proportions as the net proceeds (before deducting expenses) received by the Company from the sale of the

Shares and the total underwriting discounts and commissions received by the Underwriters in connection therewith, in each case as set forth in the table on the cover of the Prospectus, bear to the aggregate offering price of the Shares. The relative

fault of the Company, on the one hand, and the Underwriters on the other, shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a

material fact relates to information supplied by the Company or by the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

-30-

(e) Limitation on Liability. The Company and the Underwriters agree that it would not

be just and equitable if contribution pursuant to paragraph (d) above were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation that does not

take account of the equitable considerations referred to in paragraph (d) above. The amount paid or payable by an Indemnified Person as a result of the losses, claims, damages and liabilities referred to in paragraph (d) above shall be

deemed to include, subject to the limitations set forth above, any legal or other expenses reasonably incurred by such Indemnified Person in connection with any such action or claim. Notwithstanding the provisions of paragraphs (d) and (e), in

no event shall an Underwriter be required to contribute any amount in excess of the amount by which the total underwriting discounts and commissions received by such Underwriter with respect to the offering of the Shares exceeds the amount of any

damages that such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the

Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ obligations to contribute pursuant to paragraphs (d) and (e) are several in proportion to their

respective purchase obligations hereunder and not joint.

(f) Non-Exclusive Remedies. The

remedies provided for in this Section 7 paragraphs (a) through (e) are not exclusive and shall not limit any rights or remedies which may otherwise be available to any Indemnified Person at law or in equity.

8. Effectiveness of Agreement. This Agreement shall become effective as of the date first written above.

9. Termination. This Agreement may be terminated in the absolute discretion of the Representatives, by notice to the Company, if after

the execution and delivery of this Agreement and on or prior to the Closing Date or, in the case of the Option Shares, prior to the Additional Closing Date (i) trading generally shall have been suspended or materially limited on or by any of

the New York Stock Exchange or The Nasdaq Stock Market; (ii) trading of any securities issued or guaranteed by the Company shall have been suspended on any exchange or in any

over-the-counter market; (iii) a general moratorium on commercial banking activities shall have been declared by federal or New York State authorities; or

(iv) there shall have occurred any outbreak or escalation of hostilities or any change in financial markets or any calamity or crisis, either within or outside the United States, that, in the judgment of the Representatives, is material and

adverse and makes it impracticable or inadvisable to proceed with the offering, sale or delivery of the Shares on the Closing Date or the Additional Closing Date, as the case may be, on the terms and in the manner contemplated by this Agreement, the

Pricing Disclosure Package and the Prospectus.

-31-

10. Defaulting Underwriter.

(a) If, on the Closing Date or the Additional Closing Date, as the case may be, any Underwriter defaults on its obligation to purchase the

Shares that it has agreed to purchase hereunder on such date, the non-defaulting Underwriters may in their discretion arrange for the purchase of such Shares by other persons satisfactory to the Company on the

terms contained in this Agreement. If, within 36 hours after any such default by any Underwriter, the non-defaulting Underwriters do not arrange for the purchase of such Shares, then the Company shall be

entitled to a further period of 36 hours within which to procure other persons satisfactory to the non-defaulting Underwriters to purchase such Shares on such terms. If other persons become obligated or agree

to purchase the Shares of a defaulting Underwriter, either the non-defaulting Underwriters or the Company may postpone the Closing Date or the Additional Closing Date, as the case may be, for up to five full

business days in order to effect any changes that in the opinion of counsel for the Company or counsel for the Underwriters may be necessary in the Registration Statement, the Prospectus or the Pricing Disclosure Package or in any other document or

arrangement, and the Company agrees to promptly prepare any amendment or supplement to the Registration Statement, the Prospectus or the Pricing Disclosure Package that effects any such changes. As used in this Agreement, the term

“Underwriter” includes, for all purposes of this Agreement unless the context otherwise requires, any person not listed in Schedule 1 hereto that, pursuant to this Section 10, purchases Shares that a defaulting Underwriter agreed

but failed to purchase.

(b) If, after giving effect to any arrangements for the purchase of the Shares of a defaulting Underwriter or

Underwriters by the non-defaulting Underwriters and the Company as provided in paragraph (a) above, the aggregate number of Shares that remain unpurchased on the Closing Date or the Additional Closing

Date, as the case may be, does not exceed one-eleventh of the aggregate number of Shares to be purchased on such date, then the Company shall have the right to require each

non-defaulting Underwriter to purchase the number of Shares that such Underwriter agreed to purchase hereunder on such date plus such Underwriter’s pro rata share (based on the number of Shares that such

Underwriter agreed to purchase on such date) of the Shares of such defaulting Underwriter or Underwriters for which such arrangements have not been made.

(c) If, after giving effect to any arrangements for the purchase of the Shares of a defaulting Underwriter or Underwriters by the non-defaulting Underwriters and the Company as provided in paragraph (a) above, the aggregate number of Shares that remain unpurchased on the Closing Date or the Additional Closing Date, as the case may be,

exceeds one-eleventh of the aggregate amount of Shares to be purchased on such date, or if the Company shall not exercise the right described in paragraph (b) above, then this Agreement or, with respect

to any Additional Closing Date, the obligation of the Underwriters to purchase Shares on the Additional Closing Date, as the case may be, shall terminate without liability on the part of the non-defaulting

Underwriters. Any termination of this Agreement pursuant to this Section 10 shall be without liability on the part of the Company, except that the Company will continue to be liable for the payment of expenses as set forth in Section 11

hereof and except that the provisions of Section 7 hereof shall not terminate and shall remain in effect.

-32-

(d) Nothing contained herein shall relieve a defaulting Underwriter of any liability it may

have to the Company or any non-defaulting Underwriter for damages caused by its default.

11.

Payment of Expenses.

(a) Whether or not the transactions contemplated by this Agreement are consummated or this Agreement is

terminated, the Company will pay or cause to be paid all costs and expenses incident to the performance of its obligations hereunder, including without limitation, (i) the costs incident to the authorization, issuance, sale, preparation and

delivery of the Shares to the Underwriters and any transfer taxes or other similar taxes payable in that connection, including any stock or other transfer taxes and any stamp or other duties payable upon the sale, issuance or delivery of the Shares

to the Underwriters pursuant to this Agreement; (ii) the costs incident to the preparation, printing and filing under the Securities Act of the Registration Statement, the Preliminary Prospectus, any Issuer Free Writing Prospectus, any Pricing

Disclosure Package and the Prospectus (including all exhibits, amendments and supplements thereto) and the distribution thereof; (iii) the fees and expenses of the Company’s counsel and independent accountants; (iv) the fees and

expenses incurred in connection with the registration or qualification and determination of eligibility for investment of the Shares under the state or foreign securities or blue sky laws of such jurisdictions as the Representatives may designate

and the preparation, printing and distribution of a Blue Sky Memorandum (including the related fees and expenses of counsel for the Underwriters); (v) the cost of preparing stock certificates; (vi) the costs and charges of any transfer

agent and any registrar; (vii) all expenses and application fees incurred in connection with any filing with, and clearance of the offering by, FINRA; provided, that the aggregate amount payable by the Company pursuant to clauses

(iv) and (vii) shall not exceed $25,000 (excluding filing fees); (viii) all expenses incurred by the Company in connection with any “road show” presentation to potential investors (provided, however, that the Underwriters and

the Company shall each pay 50% of the cost of chartering any aircraft to be used in connection with the road show by the Company and the Underwriters); and (ix) all expenses and application fees related to the listing of the Shares on the

Nasdaq Market. It is understood that except as provided in this Section 11 and in this Agreement, the Underwriters will pay all of their costs and expenses, including fees and disbursements of their counsel, transfer taxes or other similar

taxes payable on resale of any of the Shares by them and any advertising expenses connected with any offer they make.

(b) If (i) this

Agreement is terminated pursuant to clauses (i) or (ii) of Section 9, (ii) the Company for any reason fails to tender the Shares for delivery to the Underwriters or (iii) the Underwriters decline to purchase the Shares for any reason

permitted under this Agreement, the Company agrees to reimburse the Underwriters for all out-of-pocket costs and expenses (including the fees and expenses of their

counsel) reasonably incurred by the Underwriters in connection with this Agreement and the offering contemplated hereby. For the avoidance of doubt, it is understood that the Company shall not pay or reimburse any costs, fees, taxes or expenses

incurred by any Underwriter that defaults on its obligations to purchase the Shares.

-33-

12. Persons Entitled to Benefit of Agreement. This Agreement shall inure to the

benefit of and be binding upon the parties hereto and their respective successors and the officers and directors and any controlling persons referred to herein and the affiliates of each Underwriter referred to in Section 7 hereof. Nothing in

this Agreement is intended or shall be construed to give any other person any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision contained herein. No purchaser of Shares from any Underwriter shall be

deemed to be a successor merely by reason of such purchase.

13. Survival. The respective indemnities, rights of contribution,

representations, warranties and agreements of the Company and the Underwriters contained in this Agreement or made by or on behalf of the Company or the Underwriters pursuant to this Agreement or any certificate delivered pursuant hereto shall

survive the delivery of and payment for the Shares and shall remain in full force and effect, regardless of any termination of this Agreement or any investigation made by or on behalf of the Company or the Underwriters or the directors, officers,

“Common Stock Preliminary Prospectus Supplement”), relating to an offering of common stock (the “Common Stock Offering”), and Revolution Medicines, Inc.’s preliminary prospectus supplement, dated April 13, 2026 (the

“Convertible Note Preliminary Prospectus Supplement,” and, together with the Common Stock Preliminary Prospectus Supplement, the “Preliminary Prospectus Supplements”), relating to an offering of convertible senior notes due

2033 (the “Convertible Note Offering”), and supersedes the information in the applicable Preliminary Prospectus Supplement to the extent inconsistent with the information in that Preliminary Prospectus Supplement. Terms used, but not

defined, in this pricing term sheet have the respective meanings set forth in the applicable Preliminary Prospectus Supplement. As used in this pricing term sheet, “we,” “our” and “us” refer to Revolution

for general corporate purposes, including research and development expenses, expenses relating to the potential commercialization of one or more of our product candidates, general and administrative expenses and capital expenditures. We may also use

a portion of the net proceeds to in-license, invest in or acquire businesses, technologies, products or assets that we believe are complementary to our own, although we have no current plans, commitments or

agreements with respect to any such transactions. See “Use of Proceeds” in the Common Stock Preliminary Prospectus Supplement.

must, because the Notes initially will settle T+2, specify an alternate settlement cycle at the time of such trade to prevent a failed settlement. Those purchasers should consult their advisors.

immediately before the maturity date, at a cash redemption price equal to the principal amount of the Notes to be redeemed, plus accrued and unpaid interest, if any, to, but excluding, the redemption date, but only if the last reported sale price

per share of our Common Stock exceeds 130% of the conversion price on (1) each of at least 20 trading days, whether or not consecutive, during the 30 consecutive trading days ending on, and including, the trading day immediately before the date

we send the related redemption

notice; and (2) the trading day immediately before the date we send such notice. However, we may not redeem less than all of the outstanding Notes unless at least $100.0 million aggregate principal amount of Notes are

outstanding and not called for redemption as of the time we send the related redemption notice. In addition, calling any Note for redemption will constitute a make-whole fundamental change with respect to that Note, in which case the conversion rate

applicable to the conversion of that Note will be increased in certain circumstances if it is converted after it is called for redemption. See “Description of Notes—Optional Redemption” in the Convertible Note Preliminary

Prospectus Supplement.

Use of Proceeds

We estimate that the net proceeds to us from the Convertible Note Offering will be approximately $486.8 million, after deducting the underwriting discounts and commissions and our estimated offering expenses. We intend to use

the combined net proceeds from the Convertible Note Offering and the Common Stock Offering for general corporate purposes, including research and development expenses, expenses relating to the potential commercialization of one or more of our

product candidates, general and administrative expenses and capital expenditures. We may also use a portion of the net proceeds to in-license, invest in or acquire businesses, technologies, products or assets

If such make-whole fundamental change effective date or stock price is not set forth in the table above, then:

if such stock price is between two stock prices in the table above or the make-whole fundamental change effective

date is between two dates in the table above, then the number of additional shares will be determined by straight-line interpolation between the numbers of additional shares set forth for the higher and lower stock prices in the table above or the

earlier and later dates in the table above, based on a 365- or 366-day year, as applicable; and

if the stock price is greater than $1,250.00 (subject to adjustment in the same manner as the stock prices set

forth in the column headings of the table above are adjusted, as described in the Convertible Note Preliminary Prospectus Supplement under the caption “Description of Notes—Conversion Rights—Increase in Conversion Rate in

Connection with a Make-Whole Fundamental Change—Adjustment of Stock Prices and Number of Additional Shares”), or less than $142.00 (subject to adjustment in the same manner), per share, then no additional shares will be added to the

To the addressees set forth above:

The

undersigned understands that you, as representatives of the several Underwriters (the “Representatives”), propose to enter into an underwriting agreement (the “Underwriting Agreement”) with Revolution Medicines, Inc., a

Delaware corporation (the “Company”), providing for the public offering (the “Public Offering”) by the several Underwriters named in Schedule 1 to the Underwriting Agreement (the “Underwriters”), of common stock

of the Company (the “Securities”) pursuant to a Registration Statement on Form S-3 filed with the Securities and Exchange Commission (the “SEC”). Capitalized terms used herein and not

otherwise defined shall have the meanings set forth in the Underwriting Agreement.

In consideration of the Underwriters’ agreement

to purchase and make the Public Offering of the Securities, and for other good and valuable consideration, the receipt of which is hereby acknowledged, the undersigned hereby agrees that, without the prior written consent of the Representatives on

behalf of the several Underwriters, the undersigned will not, and will not cause any direct or indirect affiliate to, in each case subject to the exceptions set forth in this letter agreement (this “Letter Agreement”), during the period

beginning on the date of this Letter Agreement and ending at the close of business on the 45th day after the date of the final

prospectus supplement relating to the Public Offering (the “Prospectus”) (such period, the

“Restricted Period”), (1) offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, lend, or otherwise transfer or dispose of,

directly or indirectly, any shares of common stock, $0.0001 par value per share, of the Company (the “Common Stock”) or any securities convertible into or exercisable or exchangeable for Common Stock (including without limitation, Common

Stock or such other securities which may be deemed to be beneficially owned by the undersigned in accordance with the rules and regulations of the SEC and securities which may be issued upon exercise of a stock option or warrant) (collectively with

the Common Stock, the “Lock-Up Securities”), (2) enter into any hedging, swap or other agreement or transaction that transfers, in whole or in part, any of the economic consequences of ownership of

the Lock-Up Securities, whether any such transaction described in clause (1) or (2) above is to be settled by delivery of Common Stock or any other Lock-Up

Securities, in cash or otherwise or (3) make any demand for or exercise any right with respect to the registration of any Lock-Up Securities, or publicly disclose the intention to do any of the foregoing.

The undersigned acknowledges and agrees that the foregoing precludes the undersigned from engaging in any hedging or other transactions or arrangements (including, without limitation, any short sale or the purchase or sale of, or entry into, any put

or call option, or combination thereof, forward, swap or any other derivative transaction or instrument, however described or defined) designed or intended, or which could reasonably be expected to lead to or result in, a sale or disposition

(whether by the undersigned or someone other than the undersigned) or transfer of any economic consequences of ownership, in whole or in part, directly or indirectly, of any Lock-Up Securities, whether any

such transaction or arrangement (or instrument provided for thereunder) would be settled by delivery of Common Stock or other securities, in cash or otherwise.

Notwithstanding the foregoing, the undersigned may:

(a) transfer or dispose of the undersigned’s Lock-Up Securities:

(i) as a bona fide gift or gifts;

(ii) by will, other testamentary document or intestacy;

partnership or adoption, not more remote than first cousin);

(iv) to a partnership, limited liability company or other entity of which the

undersigned and/or the immediate family of the undersigned are the legal and beneficial owner of all of the outstanding equity securities or similar interests;

(v) to a nominee or custodian of a person or entity to whom a disposition or transfer would be permissible under clauses (i) through

(iv) above;

-2-

(vi) if the undersigned is a corporation, partnership, limited liability company, trust or

other business entity, as part of a distribution to the members, partners, stockholders or other equity holders of the undersigned, or to another corporation, partnership, limited liability company, trust or other business entity that is an

affiliate (as defined in Rule 405 promulgated under the Securities Act of 1933, as amended) of the undersigned, or to any investment fund or other entity controlling, controlled by, managing or managed by or under common control with the undersigned

or affiliates of the undersigned (including, for the avoidance of doubt, where the undersigned is a partnership, to its general partner or a successor partnership or fund, or any other funds managed by such partnership);

(vii) by operation of law pursuant to a qualified domestic order, divorce settlement, divorce decree, separation agreement or other court

order;

(viii) to the Company from an employee or other service provider of the Company in connection with the death, disability or

termination of employment or service, in each case, of such employee or service provider;

(ix) to the Company or in open market

transactions to cover tax withholdings or remittance payments upon a vesting, exercise or settlement event of any equity award granted under a stock incentive plan, stock purchase plan or other equity award plan (such a plan, an “Equity

Plan”) described in the Registration Statement, the Pricing Disclosure Package and the Prospectus (including the documents incorporated by reference therein), provided, that any such shares of Common Stock received upon such vesting,

exercise or settlement event (other than such shares as are transferred or surrendered to the Company or sold in open market transactions in connection with such vesting, exercise or settlement event) shall be subject to the terms of this Letter

Agreement; provided, further that any open market transactions pursuant to this clause (ix) shall be limited to sales of shares of Common Stock for tax withholdings or remittance payments in connection with the vesting or settlement of

restricted stock units outstanding as of the date hereof;

(x) pursuant to a bona fide third-party tender offer, merger, consolidation or

other similar transaction that is approved by the Board of Directors of the Company and made to all holders of the Company’s capital stock involving a Change of Control (as defined below) of the Company (for purposes hereof, “Change of

Control” shall mean the transfer (whether by tender offer, merger, consolidation or other similar transaction), in one transaction or a series of related transactions, to a person or group of affiliated persons, of shares of capital stock if,

after such transfer, such person or group of affiliated persons would hold more than 50% of the outstanding voting securities of the Company (or the surviving entity)); provided, that in the event that such tender offer, merger, consolidation

or other similar transaction is not completed, the undersigned’s Lock-Up Securities shall remain subject to the provisions of this Letter Agreement; and

(xi) in connection with the sale or other transfer of Common Stock made pursuant to a trading plan designed to comply with Rule 10b5-1 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”) (as such rule was in effect at the time any such trading plan was adopted) that has been entered into by the undersigned

prior to the date of this Letter Agreement;

-3-

provided, that (A) in the case of any transfer, distribution or other disposition pursuant to

clauses (a)(i), (ii), (iii), (iv), (v), (vi) and (vii), each donee, devisee, transferee or distributee shall execute and deliver to the Representatives a lock-up letter in the form of this Letter Agreement,

(B) in the case of any transfer, distribution or other disposition pursuant to clauses (a)(ii), (iii), (iv), (v) and (vi), no filing by any party (donor, donee, transferor, transferee, distributer or distributee) under the Exchange Act, or

other public announcement shall be required or shall be made voluntarily in connection with such transfer or distribution (other than a filing on a Form 5 made after the expiration of the Restricted Period referred to above or a filing on Schedule

13D, 13F or 13G that is required to be filed during the Restricted Period), (C) in the case of clauses (a)(i), (ii), (iii), (iv), (v) and (vi) above, such transfer shall not involve a disposition for value, and (D) in the case of any

transfer or other disposition pursuant to clauses (a)(i), (vii), (viii), (ix) and (xi), if the undersigned is required to make a Form 144 filing or a filing under Section 16 of the Exchange Act reporting a reduction in the aggregate beneficial

ownership of the undersigned’s Lock-Up Securities during the Restricted Period, the undersigned shall clearly indicate in the footnotes thereto that the filing relates to the circumstances described in

clauses (a)(i), (vii), (viii), (ix) or (xi), as the case may be (including in the case of transfers or dispositions pursuant to clause (a)(i) that such transferee has executed and delivered a lock-up letter to

the Representatives) and no other public filing or announcement shall be required or shall be made voluntarily in connection with such transfer or other disposition;

(b) establish one or more trading plans after the date of this Letter Agreement pursuant to Rule 10b5-1

under the Exchange Act for the transfer or disposition of Lock-Up Securities; provided, that (1) such plans are approved by the Company and do not provide for the transfer or disposition of Lock-Up Securities during the Restricted Period, and (2) no filing by any party under the Exchange Act or other public announcement shall be required or made voluntarily in connection with such trading plan

during the Restricted Period, except as required by law or regulation, provided that to the extent such filing under the Exchange Act or other public announcement is required by law or regulation, such filing or announcement shall include a

statement to the effect that no transfers may be made pursuant to such 10b5-1 Plan during the Restricted Period; and

(c) exercise an option to purchase shares of Common Stock granted under any Equity Plan described in the Registration Statement, the Pricing

Disclosure Package and the Prospectus (including the documents incorporated by reference therein), either through cash or “cashless” exercise (the term “cashless” exercise being intended to mean the surrender of a portion of

the option shares or previously owned shares to the Company to cover payment of the exercise price); provided, that (1) the underlying shares of Common Stock issued upon exercise (other than the shares surrendered to cover payment of the

exercise price) shall continue to be subject to the restrictions on transfer set forth in this Letter Agreement, and (2) any filing under Section 16 of the Exchange Act reporting a reduction in the aggregate beneficial ownership of the

undersigned’s Lock-Up Securities during the Restricted Period shall note the applicable circumstances that cause this exception to this Letter Agreement to apply, and no other public announcement shall

be required or shall be made voluntarily in connection with such transfer.

-4-

In furtherance of the foregoing, the Company, and any duly appointed transfer agent for the

registration or transfer of the securities described herein, are hereby authorized to decline to make any transfer of securities if such transfer would constitute a violation or breach of this Letter Agreement.

The undersigned hereby represents and warrants that the undersigned has full power and authority to enter into this Letter Agreement. All

authority herein conferred or agreed to be conferred and any obligations of the undersigned shall be binding upon the successors, assigns, heirs or personal representatives of the undersigned. This Letter Agreement may be delivered via facsimile,

electronic mail (including pdf or any electronic signature complying with the U.S. federal ESIGN Act of 2000, e.g., www.docusign.com) or other transmission method and any counterpart so delivered shall be deemed to have been duly and validly

delivered and be valid and effective for all purposes.

The undersigned understands that, if either (i) the Representatives or the

Company informs the other, prior to the execution of the Underwriting Agreement, that it has determined not to proceed with the Public Offering, (ii) the Registration Statement is withdrawn, (iii) the Underwriting Agreement does not become

effective by April 30, 2026, or (iv) the Underwriting Agreement (other than the provisions thereof which survive termination) shall terminate or be terminated prior to payment for and delivery of the Common Stock to be sold thereunder,

this Letter Agreement shall automatically terminate and be of no further force and effect and the undersigned shall be released from all obligations under this Letter Agreement. The undersigned understands that the Underwriters are entering into the

Underwriting Agreement and proceeding with the Public Offering in reliance upon this Letter Agreement.

This Letter Agreement and any

claim, controversy or dispute arising under or related to this Letter Agreement shall be governed by and construed in accordance with the laws of the State of New York without regard to the conflict of laws principles that would result in the

application of the laws of any other jurisdiction.

The undersigned acknowledges and agrees that the Underwriters have not provided any

recommendation or investment advice nor have the Underwriters solicited any action from the undersigned with respect to the Public Offering of the Securities and the undersigned has consulted their own legal, accounting, financial, regulatory and

tax advisors to the extent deemed appropriate. The undersigned further acknowledges and agrees that, although the Underwriters may provide certain Regulation Best Interest and Form CRS disclosures or other related documentation to you in connection

with the Public Offering, the Underwriters are not making a recommendation to you to participate in the Public Offering, enter into this letter agreement, or sell any Securities at the price determined in the Public Offering, and nothing set forth

in such disclosures or documentation is intended to suggest that any Underwriter is making such a recommendation.

Re:

Registration Statement No. 333-277640 on Form S-3; Up to 12,147,887 Shares of Common Stock, par value $0.0001 per share

To the addressee set forth

above:

We have acted as special counsel to Revolution Medicines, Inc., a Delaware corporation (the “Company”),

in connection with the proposed issuance of up to 12,147,887 shares of common stock of the Company, $0.0001 par value per share (the “Shares”). The Shares are included in a registration statement on Form S-3 under the Securities Act of 1933, as amended (the “Act”), filed with the Securities and Exchange Commission (the “Commission”) on March 4, 2024

(Registration No. 333-277640) (as so filed and as amended, the “Registration Statement”), a base prospectus dated March 4, 2024 included in the Registration Statement (the

“Base Prospectus”) and a prospectus supplement dated April 14, 2026 filed with the Commission pursuant to Rule 424(b) under the Act (together with the Base Prospectus, the “Prospectus”), and

an underwriting agreement dated April 14, 2026, by and among J.P. Morgan Securities LLC, TD Securities (USA) LLC, and Guggenheim Securities, LLC, as representatives of the several underwriters named in the underwriting agreement, and the

Company (the “Underwriting Agreement”).

This opinion is being furnished in connection with the requirements of

Item 601(b)(5) of Regulation S-K under the Act, and no opinion is expressed herein as to any matter pertaining to the contents of the Registration Statement or the Prospectus, other than as expressly stated

herein with respect to the issue of the Shares.

As such counsel, we have examined such matters of fact and questions of law as we have

considered appropriate for purposes of this letter. With your consent, we have relied upon certificates and other assurances of officers of the Company and others as to factual matters without having independently verified such factual matters. We

are opining herein as to the General Corporation Law of the State of Delaware (the “DGCL”), and we express no opinion with respect to any other laws.

April 16, 2026

Page

Subject to the foregoing and the other matters set forth herein, it is our opinion that, as

of the date hereof, when the Shares shall have been duly registered on the books of the transfer agent and registrar therefor in the name or on behalf of the purchasers, and have been issued by the Company against payment therefor in the

circumstances contemplated by the Underwriting Agreement, the issue and sale of the Shares will have been duly authorized by all necessary corporate action of the Company, and the Shares will be validly issued, fully paid and nonassessable.

In rendering the foregoing opinion, we have assumed that the Company will comply with

all applicable notice requirements regarding uncertificated shares provided in the DGCL.

This opinion is for your benefit in connection

with the Registration Statement and may be relied upon by you and by persons entitled to rely upon it pursuant to the applicable provisions of the Act. We consent to your filing this opinion as an exhibit to the Company’s Current Report on

Form 8-K dated April 16, 2026, and to the reference to our firm in the Prospectus under the heading “Legal Matters.” In giving such consent, we do not thereby admit that we are in the category

of persons whose consent is required under Section 7 of the Act or the rules and regulations of the Commission thereunder.

Sincerely,

/s/ Latham & Watkins LLP
