c/o Sachem Head Capital Management LP

250 West 55th Street, 34th Floor

New York, New York 10019

Ladies and Gentlemen:

Twilio Inc. (the “Company”), on the one hand, and Sachem Head Capital Management LP, together with each of the parties listed on Schedule A and their respective affiliates (collectively, “Sachem Head”), on the other hand, have mutually agreed to the terms contained in this letter agreement (this “Letter Agreement”). For purposes of this Letter Agreement, we refer to each of the Company and Sachem Head as a “Party” and, collectively, as the “Parties.”

(a) Concurrently with and effective upon the execution of this Letter Agreement, Sachem Head hereby agrees that it will be deemed to have irrevocably withdrawn the notice of shareholder proposals and nomination of candidates for election to the board of directors of the Company (the “Board of Directors” or the “Board”) at the Company’s 2024 annual meeting of shareholders (the “2024 Annual Meeting”), submitted to the Company on March 11, 2024.

(b) Concurrently with and effective upon the execution of this Letter Agreement, the Board shall have increased the size of the Board to ten (10) directors and, subject to the completion of a satisfactory customary background check, appointed Andrew J. Stafman (the “New Director”) as a Class II director of the Company with a term expiring at the 2024 Annual Meeting.

(c) The Company will include the New Director on the slate of nominees recommended by the Board in the Company’s proxy materials for the 2024 Annual Meeting, subject to the New Director (i) agreeing to serve and providing to the Company all customary materials and information as are provided by all other director candidates and as are required to be or customarily included in a proxy statement filed pursuant to the proxy rules of the Securities and Exchange Commission (the “SEC”), including the New Director’s consent to being named in the proxy statement for the 2024 Annual Meeting and to serving as a director of the Company if elected and (ii) executing all documents required to be executed by all other directors nominated for election at the 2024 Annual Meeting prior to such annual meeting, provided that the Company provides the New Director with such documents concurrently with providing them to each other such director (such conditions, the “Director Nomination Conditions”). Subject to the Director Nomination Conditions, the Company shall recommend and solicit proxies for the election of the New Director at the 2024 Annual Meeting in a manner no less rigorous and favorable than the manner in which the Company supports its other director nominees. Subject to the terms of this Letter Agreement, Sachem Head and the New Director acknowledge and agree that the policies and procedures applicable to other directors (collectively, “Company Policies”) will be applicable to the New Director during his or her term of service.

(d) Sachem Head represents and warrants that, as of the date hereof, Sachem Head beneficially owns such number of shares of Class A common stock, par value $0.001 per share, of the Company (“Common Stock”) as set forth in the disclosure letter delivered to the Company immediately prior to the execution of this Letter Agreement. Sachem Head acknowledges and agrees that if Sachem Head’s aggregate Net Long Position falls below 50% of its current beneficial ownership of outstanding Common Stock (as adjusted for any combinations, splits, recapitalizations or similar actions by the Company) (the “Minimum Ownership Requirement”), Sachem Head shall (i) promptly notify the Company that Sachem Head ceases to satisfy the Minimum Ownership Requirement and (ii) cause the New Director to tender his resignation from the Board of Directors to the Board, effective immediately. Concurrently with the execution and delivery of this Letter Agreement, the New Director shall execute and deliver an irrevocable resignation in the form attached hereto as Exhibit A. For the avoidance of doubt, the Company’s obligations under Sections 1(b), 1(c), 1(f) and 1(g) of this Letter Agreement shall cease once Sachem Head ceases to meet the Minimum Ownership Requirement.

(e) Until the Standstill Termination Date, each member of Sachem Head will (i) cause, in the case of all shares of Common Stock owned of record, and (ii) cause the record owner, in the case of all shares of Common Stock beneficially owned but not owned of record, in each case directly or indirectly, by it or by any of its controlled affiliates, as of the record date for the applicable annual meeting, by proxy or in person, to be (x) present for quorum purposes and (y) voted (A) in accordance with the Board’s recommendations, as such recommendations are set forth in the applicable definitive proxy statement filed in respect thereof, including with respect to nominees of the Company for election to the Board of Directors, any advisory vote on executive compensation, and the ratification of the appointment of the Company’s independent registered public accounting firm and (B) in Sachem Head’s sole discretion with respect to other matters, including any Extraordinary Transaction that results in a change in control of the Company or the sale of substantially all of the assets of the Company.

(f) Until the Standstill Termination Date and as long as Sachem Head’s Net Long Position remains at or above the Minimum Ownership Requirement, in the event the New Director is no longer able to serve as a director of the Company for any reason, Sachem Head shall be entitled to designate a candidate for replacement for such New Director on the Board (such replacement, a “Replacement Director”), subject to the approval of the Board (which approval shall not be unreasonably withheld, conditioned or delayed), provided, however, that if the Board does not approve such Replacement Director to the Board pursuant to this paragraph 1(f), the parties shall continue to follow the procedures set forth in this paragraph 1(f) until a Replacement Director is appointed to the Board. Upon a Replacement Director’s appointment to the Board, the Board and all applicable committees of the Board shall take all necessary actions to appoint such Replacement Director to any applicable committee of the Board of which the replaced director was a member immediately prior to such replaced director’s resignation or removal. The Parties agree that a Replacement Director appointed to the Board under this Section 1(f) shall be considered the New Director for purposes of this Letter Agreement.

-2-

(g) The Company agrees that the New Director shall receive (i) the same benefits of director and officer insurance, and any indemnity and exculpation arrangements available generally to the directors of the Board and (ii) such other benefits on the same basis as all other non-management directors on the Board. The Company agrees that the New Director shall receive all Board notices and other Board materials that the other directors of the Company receive from the Company in the same manner and form and at the same time as the other directors on the Board.
