Forward-looking statements generally relate to future events or our future financial or operating performance. In some cases, you can identify forward-looking statements because they contain words such as “may,” “can,” “will,” “would,” “should,” “expects,” “plans,” “anticipates,” “could,” “intends,” “target,” “projects,” “contemplates,” “believes,” “estimates,” “predicts,” “forecasts,” “potential” or “continue” or the negative of these words or other similar terms or expressions that concern our expectations, strategy, plans or intentions. Forward-looking statements contained in this proxy statement include, but are not limited to, statements about: our environmental, social, and governance efforts, our sustainability goals and our proposed sublease.

The outcome of the events described in these forward-looking statements is subject to known and unknown risks, uncertainties, and other factors that may cause our actual results, performance, or achievements to differ materially from those described in the forward-looking statements.

The forward-looking statements contained in this proxy statement are also subject to additional risks, uncertainties, and factors, including those more fully described in our most recent filings with the Securities and Exchange Commission (the “SEC”), including our Quarterly Report on Form 10-Q for the quarter ended March 31, 2022. Further information on potential risks that could affect actual results will be included in the subsequent periodic and current reports and other filings that we make with the SEC from time to time. Moreover, we operate in a very competitive and rapidly changing environment, and new

risks and uncertainties may emerge that could have an impact on the forward-looking statements contained in this proxy statement.

Forward-looking statements represent our management’s beliefs and assumptions only as of the date such statements are made. We undertake no obligation to update any forward-looking statements made in this proxy statement to reflect events or circumstances after the date of this proxy statement or to reflect new information or the occurrence of unanticipated events, except as required by law.

PROXY STATEMENT

FOR

2022 ANNUAL MEETING OF STOCKHOLDERS

PROCEDURAL MATTERS

This proxy statement and the enclosed form of proxy are furnished in connection with the solicitation of proxies by our board of directors for use at the 2022 annual meeting of stockholders of Twilio Inc., a Delaware corporation (referred to in this proxy statement as “Twilio,” the “Company,” “we,” “us,” or “our”), and any postponements, adjournments or continuations thereof (the “Annual Meeting”). The Annual Meeting will be held virtually on Wednesday, June 22, 2022 at 9:00 a.m. Pacific Time via live audio webcast. You will be able to attend the virtual Annual Meeting, vote your shares electronically and submit your questions during the live audio webcast of the meeting by visiting www.virtualshareholdermeeting.com/TWLO2022 and entering your 16-digit control number located on your proxy card. The Notice of Internet Availability of Proxy Materials (the “Notice”) containing instructions on how to access this proxy statement and our annual report is first being mailed on or about May 5, 2022 to all stockholders entitled to vote at the Annual Meeting.

The information provided in the “question and answer” format below is for your convenience only and is merely a summary of the information contained in this proxy statement. You should read this entire proxy statement carefully. Information contained on, or that can be accessed through, our website is not intended to be incorporated by reference into this proxy statement and references to our website address in this proxy statement are inactive textual references only.

What matters am I voting on?

You will be voting on:

How does the board of directors recommend I vote on these proposals?

Our board of directors recommends a vote:

1

Who is entitled to vote?

Holders of either class of our common stock as of the close of business on April 25, 2022, the record date for the Annual Meeting, may vote at the Annual Meeting. As of the record date, there were 171,843,299 shares of our Class A common stock outstanding and there were 9,817,605 shares of our Class B common stock outstanding. Our Class A common stock and Class B common stock will vote as a single class on all matters described in this proxy statement for which your vote is being solicited. Stockholders are not permitted to cumulate votes with respect to the election of directors. Each share of Class A common stock is entitled to one vote on each proposal and each share of Class B common stock is entitled to 10 votes on each proposal. Our Class A common stock and Class B common stock are collectively referred to in this proxy statement as our “common stock.”

Registered Stockholders.    If shares of our common stock are registered directly in your name with our transfer agent, you are considered the stockholder of record with respect to those shares, and the Notice was provided to you directly by us. As the stockholder of record, you have the right to grant your voting proxy directly to the individuals listed on the proxy card or to vote online at the Annual Meeting. Throughout this proxy statement, we refer to these registered stockholders as “stockholders of record.”

Street Name Stockholders.    If shares of our common stock are held on your behalf in a brokerage account or by a bank or other nominee, you are considered to be the beneficial owner of shares that are held in “street name,” and the Notice was forwarded to you by your broker or nominee, who is considered the stockholder of record with respect to those shares. As the beneficial owner, you have the right to direct your broker, bank or other nominee as to how to vote your shares. Beneficial owners are also invited to attend the Annual Meeting. However, since a beneficial owner is not the stockholder of record, you may not vote your shares of our common stock by Internet at the Annual Meeting unless you follow your broker’s procedures for obtaining a legal proxy. If you request a printed copy of our proxy materials by mail, your broker, bank or other nominee will provide a voting instruction form for you to use. Throughout this proxy statement, we refer to stockholders who hold their shares through a broker, bank or other nominee as “street name stockholders.”

How many votes are needed for approval of each proposal?

2

What is a quorum?

A quorum is the minimum number of shares required to be present at the Annual Meeting to properly hold an annual meeting of stockholders and conduct business under our second amended and restated bylaws and Delaware law. The presence, virtually or by proxy, of the holders of a majority of the voting power of all issued and outstanding shares of our common stock entitled to vote at the Annual Meeting will constitute a quorum at the Annual Meeting. Abstentions, withheld votes and broker non-votes are counted as shares present and entitled to vote for purposes of determining a quorum.

How do I vote?

If you are a stockholder of record, there are four ways to vote:

If you plan to attend the Annual Meeting, we recommend that you also vote by proxy so that your vote will be counted if you later decide not to attend the Annual Meeting.

If you are a street name stockholder, you will receive voting instructions from your broker, bank or other nominee. You must follow the voting instructions provided by your broker, bank or other nominee in order to direct your broker, bank or other nominee on how to vote your shares. Street name stockholders should generally be able to vote by returning a voting instruction form, or by telephone or on the Internet. However, the availability of telephone and Internet voting will depend on the voting process of your broker, bank or other nominee. As discussed above, if you are a street name stockholder, you may not vote your shares by Internet at the Annual Meeting unless you obtain a legal proxy from your broker, bank or other nominee.

Can I change my vote?

Yes. If you are a stockholder of record, you can change your vote or revoke your proxy any time before the Annual Meeting by:

We encourage stockholders to reach out to us by e-mail at legalnotices@twilio.com instead of physical mail to help ensure prompt receipt of any communications related to voting.

If you are a street name stockholder, your broker, bank or other nominee can provide you with instructions on how to change your vote.

3

Why won’t there be an in-person meeting this year?

We are leveraging technology to hold a virtual Annual Meeting that expands convenient access to, and enables participation by, stockholders from any location around the world. We believe the virtual format encourages attendance and participation by a broader group of stockholders, while also reducing the costs and environmental impact associated with an in-person meeting. You will be able to vote and submit your questions during the meeting at www.virtualshareholdermeeting.com/TWLO2022. There will not be a physical meeting location. Our virtual Annual Meeting will be governed by our rules of conduct and procedures, which will be posted at www.virtualshareholdermeeting.com/TWLO2022 on the date of the Annual Meeting. We have designed the format of the virtual Annual Meeting so that stockholders have the same rights and opportunities to vote and participate as they would have at a physical meeting. Stockholders will be able to submit questions online before and during the meeting, providing our stockholders with the opportunity for meaningful engagement with the Company.

What do I need to be able to attend the Annual Meeting online?

We will be hosting our Annual Meeting via live audio webcast only. If you are a stockholder as of the record date of April 25, 2022 and wish to virtually attend the Annual Meeting, you will need the 16-digit control number, which is located on your Notice of Internet Availability of Proxy Materials or on your proxy card (if you receive a printed copy of the proxy materials). Instructions on how to participate in the Annual Meeting are also posted online at www.proxyvote.com. The webcast will start at 9:00 a.m., Pacific Time on June 22, 2022. Stockholders may vote and ask questions while attending the Annual Meeting online.

Use of cameras and recording devices is prohibited while virtually attending the live audio webcast.

What is the effect of giving a proxy?

Proxies are solicited by and on behalf of our board of directors. Jeff Lawson and Khozema Shipchandler have been designated as proxy holders by our board of directors. When proxies are properly dated, executed and returned, the shares represented by such proxies will be voted at the Annual Meeting in accordance with the instructions of the stockholder. If no specific instructions are given, however, the shares will be voted in accordance with the recommendations of our board of directors as described above. If any matters not described in this proxy statement are properly presented at the Annual Meeting, the proxy holders will use their own judgment to determine how to vote the shares. If the Annual Meeting is adjourned, the proxy holders can vote the shares on the new Annual Meeting date as well, unless you have properly revoked your proxy instructions, as described above.

Why did I receive a Notice of Internet Availability of Proxy Materials instead of a full set of proxy materials?

In accordance with the rules of the SEC, we have elected to furnish our proxy materials, including this proxy statement and our annual report, primarily via the Internet. The Notice containing instructions on how to access our proxy materials is first being mailed on or about May 5, 2022 to all stockholders entitled to vote at the Annual Meeting. Stockholders may request to receive all future proxy materials in printed form by mail or electronically by e-mail by following the instructions contained in the Notice. We encourage stockholders to take advantage of the availability of our proxy materials on the Internet to help reduce the environmental impact and cost of our annual meetings of stockholders.

How are proxies solicited for the Annual Meeting?

Our board of directors is soliciting proxies for use at the Annual Meeting. All expenses associated with this solicitation will be borne by us. We will reimburse brokers or other nominees for reasonable expenses that they incur in sending our proxy materials to you if a broker, bank or other nominee holds

4

shares of our common stock on your behalf. In addition, our directors and employees may also solicit proxies in person, by telephone or by other means of communication. Our directors and employees will not be paid any additional compensation for soliciting proxies.

How may my brokerage firm or other intermediary vote my shares if I fail to provide timely directions?

Brokerage firms and other intermediaries holding shares of our common stock in street name for their customers are generally required to vote such shares in the manner directed by their customers. In the absence of timely directions, your broker will have discretion to vote your shares on our sole “routine” matter: the proposal to ratify the appointment of KPMG LLP as our independent registered public accounting firm for our fiscal year ending December 31, 2022. Your broker will not have discretion to vote on any other proposals, which are “non-routine” matters, absent direction from you.

Where can I find the voting results of the Annual Meeting?

We will announce preliminary voting results at the Annual Meeting. We will also disclose voting results on a Current Report on Form 8-K that we will file with the SEC within four business days after the Annual Meeting. If final voting results are not available to us in time to file a Current Report on Form 8-K within four business days after the Annual Meeting, we will file a Current Report on Form 8-K to publish preliminary results and will provide the final results in an amendment to the Current Report on Form 8-K as soon as they become available.

I share an address with another stockholder, and we received only one paper copy of the proxy materials. How may I obtain an additional copy of the proxy materials?

We have adopted a procedure called “householding,” which the SEC has approved. Under this procedure, we deliver a single copy of the Notice and, if applicable, our proxy materials, to multiple stockholders who share the same address, unless we have received contrary instructions from one or more of such stockholders. This procedure reduces our printing costs, mailing costs and fees. Stockholders who participate in householding will continue to be able to access and receive separate proxy cards. Upon written or oral request, we will deliver promptly a separate copy of the Notice and, if applicable, our proxy materials, to any stockholder at a shared address to which we delivered a single copy of any of these materials. To receive a separate copy, or, if a stockholder is receiving multiple copies, to request that we only send a single copy of the Notice and, if applicable, our proxy materials, such stockholder may contact us at (415) 914-1444 or:

Twilio Inc.

Attention: Investor Relations

San Francisco, California 94105

ir@twilio.com

We encourage stockholders to contact us by telephone or e-mail instead of physical mail to help ensure timely receipt of any request for proxy materials.

Street name stockholders may contact their broker, bank or other nominee to request information about householding.

What is the deadline to propose actions for consideration at next year’s annual meeting of stockholders or to nominate individuals to serve as directors?

Secretary in a timely manner. For a stockholder proposal to be considered for inclusion in our proxy statement for the 2023 annual meeting of stockholders, our Corporate Secretary must receive the written proposal at our principal executive offices not later than January 5, 2023.

Our second amended and restated bylaws also establish an advance notice procedure for stockholders who wish to present a proposal before an annual meeting of stockholders but do not intend for the proposal to be included in our proxy statement. Our second amended and restated bylaws provide that the only business that may be conducted at an annual meeting of stockholders is business that is (i) specified in our proxy materials with respect to such annual meeting, (ii) otherwise properly brought before such annual meeting by or at the direction of our board of directors or (iii) properly brought before such meeting by a stockholder of record entitled to vote at such annual meeting who has delivered timely written notice to our Corporate Secretary, which notice must contain the information specified in our second amended and restated bylaws. To be timely for the 2023 annual meeting of stockholders, our Corporate Secretary must receive the written notice at our principal executive offices:

In the event that we hold the 2023 annual meeting of stockholders more than 30 days before or more than 60 days after the one-year anniversary of the Annual Meeting, then, for notice by the stockholder to be timely, it must be received by the secretary not earlier than the close of business on the 120th day prior to such annual meeting and not later than the close of business on the later of the 90th day prior to such annual meeting, or the tenth day following the day on which public announcement of the date of such annual meeting is first made.

If a stockholder who has notified us of his, her or its intention to present a proposal at an annual meeting of stockholders does not appear to present his, her or its proposal at such annual meeting, we are not required to present the proposal for a vote at such annual meeting.

Nomination of Director Candidates

Holders of our common stock may propose director candidates for consideration by our nominating and corporate governance committee. Any such recommendations should include the nominee’s name and qualifications for membership on our board of directors and should be directed to our Chief Legal Officer at the address set forth above. For additional information regarding stockholder recommendations for director candidates, see the section titled “Board of Directors and Corporate Governance—Stockholder Recommendations and Nominations to the Board of Directors.”

In addition, our second amended and restated bylaws permit stockholders to nominate directors for election at an annual meeting of stockholders. To nominate a director, the stockholder must provide the information required by our second amended and restated bylaws. In addition, the stockholder must give timely notice to our Corporate Secretary in accordance with our second amended and restated bylaws, which, in general, require that the notice be received by our Corporate Secretary within the time periods described above under the section titled “Stockholder Proposals” for stockholder proposals that are not intended to be included in a proxy statement.

In addition to satisfying the foregoing requirements under our second amended and restated bylaws, to comply with the universal proxy rules in connection with our 2023 annual meeting, stockholders who

Director Independence

Our Class A common stock is listed on The New York Stock Exchange and the Long-Term Stock Exchange. Under the NYSE Listing Standards and the LTSE Listing Standards, independent directors must comprise a majority of a listed company’s board of directors. In addition, the NYSE Listing Standards and LTSE Listing Standards require that, subject to specified exceptions, each member of a listed company’s audit, compensation and nominating and corporate governance committees be independent. Under the NYSE Listing Standards and LTSE Listing Standards, a director will only qualify as an “independent director” if, in the opinion of that listed company’s board of directors, that director does not have a relationship that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director.

Audit committee members must also satisfy the additional independence criteria set forth in Rule 10A-3 under the Exchange Act, the NYSE Listing Standards and the LTSE Rules. Compensation and talent management committee members must also satisfy the additional independence criteria set forth in Rule 10C-1 under the Exchange Act, the NYSE Listing Standards and the LTSE Listing Standards.

Our board of directors has undertaken a review of the independence of each director. Based on information provided by each director concerning his or her background, employment and affiliations, our board of directors has determined that Messrs. Dalzell, Deeter, Epstein, Immelt and Patrick, and Mses. Dubinsky and Rottenberg do not have a relationship that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director and that each of these directors is “independent” as that term is defined under the NYSE Listing Standards and LTSE Listing Standards. In making these determinations, our board of directors considered the current and prior relationships that each non-employee director has with our Company and all other facts and circumstances our board of directors deemed relevant in determining their independence, including the beneficial ownership of our capital stock by each non-employee director, and the transactions involving them described in the section titled “Certain Relationships and Related Party Transactions.”

Board Leadership Structure

Chairperson of the Board

Mr. Lawson, our co-founder and Chief Executive Officer, also serves as Chairperson of our board of directors. As our co-founder and Chief Executive Officer, Mr. Lawson possesses detailed and in-depth knowledge of the issues, opportunities and challenges facing the company and its business and is best positioned to identify strategic priorities, lead critical discussions and execute our business plans. We believe this extensive company-specific experience and expertise of Mr. Lawson, together with the outside experience, oversight and expertise of our independent directors, allows for differing perspectives and roles regarding strategy development that benefit our stockholders.

Lead Independent Director

Our board has a strong and empowered lead independent director who provides an effective independent voice in our leadership structure. Since Mr. Lawson is the Chairperson of our board of directors and is not an “independent” director pursuant to the NYSE Listing Standards and LTSE Listing Standards, we appointed Mr. Jeff Epstein to serve as our lead independent director in December 2017. Mr. Epstein serves as a liaison between our Chief Executive Officer and Chairperson, and our independent directors, and performs such additional duties as our board of directors may otherwise determine and delegate. In addition, our independent directors, who are the sole members of each of our board

11

committees, provide strong independent leadership and oversight for each of these committees. Our independent directors generally meet in executive session after each meeting of the board of directors. At each such meeting, the presiding director for each executive session of our board of directors will be either (i) the lead independent director or (ii) chosen by the independent directors.

Our board believes that this leadership structure, coupled with a strong emphasis on board independence, provides effective independent oversight of management while allowing both the board of directors and management to benefit from Mr. Lawson’s leadership and years of experience in the company’s business and the technology industry.

We believe that the structure of our board of directors and committees of our board of directors provides effective independent oversight of management, while Mr. Lawson’s combined role enables strong leadership, creates clear accountability and enhances our ability to develop and execute our strategy and communicate our message clearly and consistently to stockholders.

Board Meetings and Committees

Our board of directors may establish the authorized number of directors from time to time by resolution. Our board of directors currently consists of eight members.

During our fiscal year ended December 31, 2021, our board of directors held six meetings (including regularly scheduled and special meetings), and each director attended at least 75% of the aggregate of (i) the total number of meetings of our board of directors held during the period for which he or she had been a director and (ii) the total number of meetings held by all committees of our board of directors on which he or she served during the periods that he or she served.

Although our Corporate Governance Guidelines do not have a formal policy regarding attendance by members of our board of directors at annual meetings of stockholders, we encourage, but do not require, our directors to attend. All members of our board of directors then serving in such capacity, other than Mr. Epstein, attended our 2021 annual meeting of stockholders.

Our board of directors has established an audit committee, a compensation and talent management committee and a nominating and corporate governance committee. The composition and responsibilities of each of the committees of our board of directors is described below. Members serve on these committees until their resignation or until as otherwise determined by our board of directors.

Audit Committee

Our audit committee consists of Mr. Epstein and Mses. Dubinsky and Rottenberg, with Mr. Epstein serving as Chairperson. Each member of our audit committee meets the requirements for independence under the NYSE Listing Standards, LTSE Listing Standards and SEC rules. Each member of our audit committee also meets the financial literacy and sophistication requirements of the NYSE Listing Standards and LTSE Listing Standards. In addition, our board of directors has determined that each of Mr. Epstein and Ms. Dubinsky is an audit committee financial expert within the meaning of Item 407(d) of Regulation S-K under the Securities Act of 1933, as amended (the “Securities Act”).

No member of our audit committee may simultaneously serve on the audit committee of more than three public companies unless our board of directors determines that such simultaneous service would not impair the ability of such member to effectively serve on our audit committee. Mr. Epstein currently serves on the audit committees of three other public companies. Given Mr. Epstein’s extensive experience as a Chief Financial Officer, his proficiency in accounting, and his knowledge of our Company, our board has determined that Mr. Epstein’s simultaneous service on the audit committees of more than three public companies does not impair his ability to effectively serve on our audit committee. Mr. Epstein attended 100% of the meetings held by our audit committee and board of directors during fiscal year 2021.

12

Our audit committee, among other things:

Our audit committee operates under a written charter that satisfies the applicable rules and regulations of the SEC, the NYSE Listing Standards and the LTSE Listing Standards. A copy of the charter of our audit committee is available on our website at https://investors.twilio.com.

Our audit committee held nine meetings during fiscal year 2021.

Compensation and Talent Management Committee

Our compensation and talent management committee consists of Messrs. Immelt and Patrick (and Mr. Dalzell, for a portion of 2021 and Ms. Donio until her resignation, effective April 29, 2022). Ms. Donio served as Chairperson of our compensation and talent management committee during 2021. Mr. Immelt succeeded Ms. Donio as Chairperson effective April 29, 2022 in connection with Ms. Donio’s resignation from our board of directors and compensation and talent management committee. Each member of our compensation and talent management committee meets the requirements for independence under the NYSE Listing Standards, LTSE Listing Standards and SEC rules. Each member of our compensation and talent management committee is also a non-employee director, as defined pursuant to Rule 16b-3 promulgated under the Exchange Act (“Rule 16b-3”). During fiscal year 2021, Mr. Dalzell also served on the compensation and talent management committee and resigned from the compensation and talent management committee effective April 1, 2021. Mr. Dalzell met the requirements for independence under the NYSE Listing Standards, LTSE Listing Standards and SEC rules, and he is a non-employee director, as defined pursuant to Rule 16b-3. Our compensation and talent management committee, among other things:

13

Our compensation and talent management committee operates under a written charter that satisfies the applicable rules of the SEC, the NYSE Listing Standards and the LTSE Listing Standards. A copy of the charter of our compensation and talent management committee is available on our website at https://investors.twilio.com.

Our compensation and talent management committee held six meetings during fiscal year 2021.

Nominating and Corporate Governance Committee

Our nominating and corporate governance committee consists of Ms. Rottenberg and Messrs. Dalzell and Deeter, with Ms. Rottenberg serving as Chairperson. Each member of our nominating and governance committee meets the requirements for independence under the NYSE Listing Standards, LTSE Listing Standards and SEC rules. Our nominating and corporate governance committee, among other things:

Our nominating and corporate governance committee operates under a written charter that satisfies the applicable NYSE Listing Standards and the LTSE Listing Standards. A copy of the charter of our nominating and corporate governance committee is available on our website at https://investors.twilio.com.

Our nominating and corporate governance committee held four meetings during fiscal year 2021.

Compensation and Talent Management Committee Interlocks and Insider Participation

During 2021, Ms. Donio and Messrs. Dalzell (with respect to Mr. Dalzell, for a portion of the year), Immelt and Patrick served on the compensation and talent management committee. Effective April 29, 2022, Ms. Donio resigned from our board of directors and compensation and talent management committee. None of the members of our compensation and talent management committee is or has been an officer or employee of our Company. None of our executive officers currently serves, or in the past year has served, as a member of the board of directors or compensation and talent management committee (or other board committee performing equivalent functions) of any entity that has one or more of its executive officers serving on our board of directors or compensation and talent management committee. See the section titled “Certain Relationships and Related Party Transactions” for information about related party transactions involving members of our compensation and talent management committee or their affiliates.

Identifying and Evaluating Director Nominees

The board of directors has delegated to the nominating and corporate governance committee the responsibility of identifying suitable candidates for nomination to the board of directors (including candidates to fill any vacancies that may occur) and assessing their qualifications in light of the policies and principles in our corporate governance guidelines and the committee’s charter. The nominating and corporate governance committee may gather information about the candidates through interviews, detailed questionnaires, comprehensive background checks or any other means that the nominating and corporate governance committee deems to be appropriate in the evaluation process. The nominating and corporate governance committee then meets as a group to discuss and evaluate the qualities and skills of each candidate, both on an individual basis and taking into account the overall composition and needs of

14

the board of directors. Based on the results of the evaluation process, the nominating and corporate governance committee recommends candidates for the board of directors’ approval as director nominees for election to the board of directors.

Minimum Qualifications and Membership on other Boards

Twilio has a highly effective and engaged board of directors, and members of our board of directors are expected to prepare for, attend, and participate in all board of directors and applicable committee meetings and are encouraged to attend our annual meetings of stockholders. The board of directors does not believe that explicit limits on the number of other boards of directors on which the directors may serve, or on other activities the directors may pursue, are appropriate. Rather, we believe that our directors’ service on other companies’ boards enables them to contribute valuable knowledge and perspective to our board of directors. Nonetheless, the board of directors recognizes that carrying out the duties of a director requires a significant commitment of time and attention, and excessive time commitments - whether other board service or otherwise—may interfere with the ability to fulfill Twilio board of director responsibilities. Our Corporate Governance Guidelines require directors to notify the chairperson of the nominating and corporate governance committee in connection with joining another board and regularly update the company regarding other directorship and significant other commitments, so that the potential for conflicts or other factors that may compromise a director’s ability to perform their duties may be fully assessed.

Our board of directors has delegated to our nominating and corporate governance committee the responsibility of identifying suitable candidates for nomination to our board of directors (including candidates to fill any vacancies that may occur) and assessing their qualifications in light of the policies and principles in our Corporate Governance Guidelines and the committee’s charter. Our nominating and corporate governance committee uses a variety of methods for identifying and evaluating director nominees and considers all facts and circumstances that it deems appropriate or advisable. In its identification and evaluation of director candidates, our nominating and corporate governance committee considers the current size and composition of our board of directors and the needs of our board of directors and the respective committees of our board of directors. Some of the qualifications that our nominating and corporate governance committee considers include:

In addition to the above criteria, and although there are no further stated minimum criteria for director nominees, although our nominating and corporate governance committee may also consider such other factors as it may deem, from time to time, are in our and our stockholders’ best interests.

Our nominating and corporate governance committee reviews the totality of the circumstances of each nominee and each board member to assess the ability of such individuals to devote the requisite time to fulfilling the responsibilities of service on our board of directors and applicable committees. Our nominating and corporate governance committee evaluates many factors when assessing the effectiveness and active involvement of each director, including the director’s attendance at board and committee

15

meetings, participation and level of engagement during these meetings, the role played by the director on our board of directors, as well as on the other boards, including committee membership and chairperson designation, and the experience and expertise of the director, including both relevant industry experience and service on other public company boards, which enable the director to serve on multiple boards effectively.

Although our board of directors does not maintain a specific policy with respect to the number of diverse individuals on our board of directors, our board of directors believes that our board of directors should be a diverse body, and our nominating and corporate governance committee endeavors to consider candidates who represent a mix of backgrounds including breadth and quality of experience, personal and professional experience, expertise, culture, race, ethnicity, gender and sexual orientation, including lived experience. In making determinations regarding nominations of directors, our nominating and corporate governance committee takes into account the benefits of diverse viewpoints. Our nominating and corporate governance committee also considers these and other factors as it oversees the annual board of directors and committee evaluations. After completing its review and evaluation of director candidates, our nominating and corporate governance committee recommends to our full board of directors the director nominees for selection.

Stockholder Recommendations and Nominations to the Board of Directors

Stockholders may submit recommendations for director candidates to the nominating and corporate governance committee by sending the individual’s name and qualifications to our Chief Legal Officer at Twilio Inc., 101 Spear Street, First Floor, San Francisco, California 94105, who will forward all recommendations to the nominating and corporate governance committee. The nominating and corporate governance committee will evaluate any candidates recommended by stockholders against the same criteria and pursuant to the same policies and procedures applicable to the evaluation of candidates proposed by directors or management.

Stockholder and Other Interested Party Communications

The board of directors provides to every stockholder and any other interested parties the ability to communicate with the board of directors, as a whole, and with individual directors on the board of directors through an established process for stockholder communication. For a stockholder communication directed to the board of directors as a whole, stockholders and other interested parties may send such communication to our Chief Legal Officer via U.S. Mail or Expedited Delivery Service to: Twilio Inc., 101 Spear Street, First Floor, San Francisco, California 94105, Attn: Board of Directors c/o Chief Legal Officer.

For a stockholder or other interested party communication directed to an individual director in his or her capacity as a member of the board of directors, stockholders and other interested parties may send such communication to the attention of the individual director via U.S. Mail or Expedited Delivery Service to: Twilio Inc., 101 Spear Street, First Floor, San Francisco, California 94105, Attn: [Name of Individual Director].

We encourage stockholders to e-mail any such communications to us at legalnotices@twilio.com to help ensure prompt receipt. Our Chief Legal Officer, in consultation with appropriate members of our board of directors as necessary, will review all incoming communications and, if appropriate, all such communications will be forwarded to the appropriate member or members of our board of directors, or if none is specified, to the Chairperson of our board of directors.

Corporate Governance Guidelines and Code of Conduct

Our board of directors has adopted Corporate Governance Guidelines that address items such as the qualifications and responsibilities of our directors and director candidates and corporate governance policies and standards applicable to us in general. In addition, our board of directors has adopted a code of

16

conduct that applies to all of our employees, officers and directors, including our Chief Executive Officer, Chief Financial Officer, Chief Operating Officer and other executive and senior financial officers. A copy of our Corporate Governance Guidelines and Code of Conduct is available on our Internet website at https://investors.twilio.com and may also be obtained without charge by contacting our Corporate Secretary at Twilio Inc., 101 Spear Street, First Floor, San Francisco, California 94105. We intend to disclose any amendments to our Code of Conduct, or waivers of its requirements, on our website or in filings under the Exchange Act, as required by the applicable rules and exchange requirements. During fiscal year 2021, no waivers were granted from any provision of our Code of Conduct.

Our Commitment to Environmental, Social and Governance Matters

At Twilio, we recognize the impact that a business can have on its surrounding community and environment, and we believe that an organization has the responsibility to be a good corporate citizen. We also value our employees and recognize the critical roles that they play in the achievement of our long-term goals and overall success. The following is intended as a summary of some of the steps we are taking to create a safe and inclusive workplace for our employees and to foster positive impact in our communities and for our stakeholders. More information about our environmental, social and governance efforts can be found in our 2021 Impact and DEI Report, available on the Governance section of our website at https://investors.twilio.com. Information referenced on our website does not constitute part of this proxy statement.

Board Oversight

We are committed to sound governance and oversight of our impact on the surrounding community and environment. This is one of the reasons that our board of directors has delegated formal oversight of our environmental, social and governance activities, programs and disclosure to our nominating and corporate governance committee. At each regularly scheduled meeting of our nominating and corporate governance committee, members of the Company’s management provide our nominating and corporate governance committee with formal updates on the Company’s environmental, social and governance activities and programs.

Environmental

We recognize the impact that companies can have on the environment and we are working to integrate sustainability initiatives into our business practices, including the evaluation of energy conservation initiatives and renewable energy purchases that can help reduce greenhouse emissions at our facilities. Our goal is to limit our impact on climate change and to carry out our business activities in a sustainable manner. As a business that is conducted largely online, our carbon footprint may be smaller than those of manufacturing or other businesses, but we still strive to limit our impact on climate change. We have also begun to measure our carbon footprint with the goal of setting a greenhouse gas reduction target in the future. Additionally, we are monitoring our water usage and creating a systematic global approach to responsibly dispose of our electronic waste, including through participation in vendor buy-back programs or e-cycling. Finally, we are fostering the promotion of conservation by recycling, composting, and source reduction in all of our offices globally.

Social Impact of Product Portfolio

Twilio’s mission is to unleash the imagination of builders. As a company, we’ve long been inspired by the imagination of builders tackling complex social problems. We started Twilio.org to be the engine behind social impact organizations, helping them use our digital engagement tools and financial resources to supercharge their reach and scale their impact. We partner with nonprofits, social enterprises, international NGOs, and local governments that deliver support in a crisis, connect people with life-changing resources, and inspire action for the greater good. Whether it’s fueling the technology behind crisis hotlines, building video applications that connect teachers and students for distance learning, or

17

using our voice and SMS products to organize underrepresented communities to vote, our social impact partners are engaging people around the world to build the future that they want. In 2021, impact organizations leveraged Twilio to reach over 500 million people.

Effective communication is critical in helping social impact organizations listen and engage with the people that they serve. That’s why we sell our communication products at a discount to these types of organizations. We then reinvest the profit back into our social initiatives. This means as our revenues grow, so does our social impact. This increased revenue translates to more grants, employee volunteering, and technical resources available for organizations using technology to advance their missions.

Community Involvement and Philanthropy

One form of employee volunteering is the WePledge 1% program that Twilio.org launched in 2019. WePledge 1% is our volunteer impact and giving program in which employees voluntarily pledge to give 1% of their own time, income, or equity (or a combination) to causes that resonate with them. Since the program’s launch in September 2019, over 3,400 of our employees have taken the pledge to commit 1%, resulting in the donation of over three million dollars and over 20,000 volunteer hours.

As the scale and frequency of global crises increase, social impact organizations are innovating to serve their communities and treat people as individuals with dignity. Our goal at Twilio.org is to unleash our product, people, and capital to support 1 billion people annually. We know that when organizations pair their local, first-hand expertise with the scale of technology, more people around the world have the opportunity to thrive.

In 2015, we reserved 1% of our Class A common stock to fund our social impact at Twilio.org. In March 2019, we increased the Twilio.org share reserve by 203,658 shares of Class A common stock to account for a similar program previously operated by SendGrid, Inc. (one of our wholly owned subsidiaries, which we acquired in February 2019). Since 2016, Twilio.org has given approximately $124 million in product credits, donations, grants and investments, consistent with its philanthropic goals.

Compliance & Ethics

Our culture of integrity starts with our Corporate Governance Guidelines and Code of Conduct, and includes efforts in risk assessment, development of policies, procedures, training, auditing, monitoring, investigations, and remediation of potential compliance matters. We have also implemented mandatory anti-harassment, anti-corruption and anti-bribery training as well as more targeted compliance training aimed at addressing the compliance risks of specific roles and business functions.

Furthermore, in order to promote a high standard of ethical and professional conduct within our Company, we have engaged with an impartial third party to administer an ethics reporting hotline where, as permitted by law, employees, contractors, customers and vendors may address any issues on a confidential and anonymous basis. Employees may choose the method with which they are most comfortable to discuss any issues or complaints, whether it is through their manager, our human resources partners, or the reporting hotline. In addition, our Code of Conduct applies to all of our employees, including our officers and board of directors. Violations of the Code of Conduct may result in disciplinary action, up to and including termination of employment.

Customer Protection and Data Privacy

We are committed to protecting the privacy and data of our developer ecosystem, customers and users. We have implemented policies and procedures that facilitate compliance with applicable privacy laws, including the California Consumer Privacy Act and the General Data Protection Regulation (“GDPR”), and work to use privacy by design in our review and building processes. For example, in 2016, even before GDPR became effective, we started the process of putting in place our own Binding Corporate Rules (“BCRs”)—considered one of the highest global standards for data protection that a

18

company can have. Our BCRs codify our guiding principles and approach to compliance with data protection laws when processing personal information.

In addition to working to maintain data privacy and security, we have proactively taken steps to provide increased visibility to the Twilio community around government requests received for customer information by municipal, state, provincial and federal governments globally. We do this by publishing semi-annual transparency reports. Our transparency reports document the total volume of government requests for information received by us, how we responded to the requests, and how often we notified users of the requests.

Data Security

Furthermore, we train employees on policies and procedures for secure data handling and use physical and procedural safeguards to help keep our facilities and equipment secure. All of our employees and contractors are required to complete privacy and security training every year.

Diversity & Inclusion

At Twilio, we are driving a diversity, equity and inclusion (“DEI”) strategy based on the principles of antiracism. We believe that we can effectively promote equity in the workplace when we focus on transformational change at the individual and leadership levels. By educating and empowering Twilions to think and operate through an antiracist lens, we’ll be able to build a more diverse workforce, promote equity for all communities in the workplace and foster safe, inclusive environments. Twilio publishes its gender and ethnic diversity data in its Impact and DEI Report, which is available on the Governance section of our website at https://investors.twilio.com.

In 2020 we created our first set of company-wide racial justice and equity business priorities and measures, and we have since began the work to embed and operationalize antiracism across the business, with a strong focus on education. In 2021, 100% of our executive team participated in two antiracism workshops and 86% of VPs and above participated in an in-depth antiracism workshop, with continued learning planned for more Twilions in 2022. We expanded our partnerships with global organizations to help us find, grow, and keep diverse talent in various demographics, regions, and countries. Lastly, 50% of employee resource group (“ERG”) specific programming and events promoted antiracist learning in the workplace.

We will continue to grow our DEI resources and global footprint to make sure our antiracism strategy scales along with the business. Most recently, we expanded the DEI team and launched new ERG chapters globally to ensure we are translating antiracism and amplifying DEI efforts across all teams and regions.

Risk Management

Risk is inherent with every business, and we face a number of risks, including strategic, financial, business and operational, cyber security, legal and compliance, and reputational. We have designed and implemented processes to manage risk in our operations. Management is responsible for the day-to-day management of risks the Company faces, while our board of directors, as a whole and assisted by its committees, has responsibility for the oversight of risk management. In addition, every employee is required to complete data privacy, cybersecurity and code of conduct training upon joining the Company and each year thereafter. In its risk oversight role, our board of directors has the responsibility to satisfy itself that the risk management processes designed and implemented by management are appropriate and functioning as designed.

Our board of directors believes that open communication between management and our board of directors is essential for effective risk management and oversight. Our board of directors meets with our Chief Executive Officer and other members of the senior management team at quarterly meetings of our board of directors, where, among other topics, they discuss strategy and risks facing the Company, as well as such other times as they deem appropriate.

19

While our board of directors is ultimately responsible for risk oversight, our board committees assist our board of directors in fulfilling its oversight responsibilities in certain areas of risk. Our audit committee assists our board of directors in fulfilling its oversight responsibilities with respect to risk management in the areas of internal control over financial reporting and disclosure controls and procedures, cybersecurity and security, legal and regulatory compliance, and discusses with management and the independent auditor guidelines and policies with respect to risk assessment and risk management. On a quarterly basis, members of our management team update the audit committee on the status of key risks impacting the Company. Our audit committee also reviews our major financial risk exposures and the steps management has taken to monitor and control these exposures. Our audit committee also monitors certain key risks on a regular basis throughout the fiscal year, such as risk associated with internal control over financial reporting and liquidity risk. Our nominating and corporate governance committee assists our board of directors in fulfilling its oversight responsibilities with respect to the management of risk associated with board organization, membership and structure, and corporate governance. Our compensation and talent management committee assesses risks created by the incentives inherent in our compensation programs, policies and practices and those related to human capital management issues. Finally, our full board of directors reviews strategic and operational risk in the context of reports from the management team, receives reports on all significant committee activities at each regular meeting, and evaluates the risks inherent in significant transactions.

Non-Employee Director Compensation

Non-Employee Director Compensation Policy

We have adopted a compensation policy for our non-employee directors (as amended and restated from time to time, the “Non-Employee Director Compensation Policy”) to attract, retain and award these individuals and align their long-term interests with those of the Company and our stockholders. Our non-employee directors are paid in the form of restricted stock units (“RSUs”) only and do not receive cash compensation. Employee directors receive no additional compensation for their service as a director.

Decisions regarding the Non-Employee Director Compensation Policy are approved by our board of directors based on recommendations from our compensation and talent management committee. Our compensation and talent management committee conducts an annual evaluation of the design and competitiveness of our Non-Employee Director Compensation Policy in light of best practices, market trends and a competitive market analysis of data for the Company’s compensation peer group prepared by its compensation consultant, and makes appropriate recommendations to our board of directors with respect to the compensation of our non-employee directors.

During 2021, our compensation and talent management committee engaged Compensia, Inc. (“Compensia”), a national compensation consulting firm, as its compensation consultant to advise on, among other things, non-employee director compensation matters. In doing so, our compensation and talent management committee reviewed and considered a peer group compensation data analysis prepared by Compensia. Our compensation and talent management committee targeted non-employee director compensation, to consist solely of RSUs, to the 50^th percentile relative to our peers. In May 2021, upon the recommendation of the compensation and talent management committee, our board of directors approved the following changes to our Non-Employee Director Compensation Policy for fiscal 2021: (i) increase the annual equity retainer for the lead independent director from $20,000 to $23,000; (ii) increase the annual equity retainer for members of the audit committee (other than the chairperson) from $11,000 to $13,000; (iii) increase the annual equity retainer for the audit committee chairperson from $22,000 to $26,000; (iv) increase the annual equity retainer for members of the compensation and talent management committee (other than the chairperson) from $9,000 to $10,000; (v) increase the annual equity retainer for the compensation and talent management committee chairperson from $18,000 to $20,000; (vi) increase the annual equity retainer for members of the nominating and corporate governance committee (other than the chairperson) from $5,000 to $6,000 (vii) increase the annual equity retainer for the nominating and

20

corporate governance committee chairperson from $10,000 to $12,000; (viii) increase the Initial Equity Grant (as defined below) from $440,000 to $575,000; and (ix) pay all annual retainers for board membership, lead independent director and committee membership in the form of RSUs in lieu of cash compensation.

For purposes of the amounts described in this section, the values are calculated as set forth in the Non-Employee Director Compensation Policy. For the aggregate grant date fair value of the RSUs awarded to the non-employee directors in the fiscal year ended December 31, 2021, calculated in accordance with FASB ASC Topic 718, please see “2021 Non-Employee Director Compensation Table” below.

Annual Equity Retainers

For fiscal 2021, our non-employee directors received compensation in the form of RSUs only, the values of which are as set forth below.

Annual Equity Grants

In addition, on the date of our annual meeting of stockholders, each non-employee director who continued as a member of our board of directors following such annual meeting of stockholders received a grant of RSUs having a value of $250,000 (the “Annual Equity Grant”).

During fiscal year 2021, the number of RSUs for the Annual Equity Grant was determined by dividing the applicable values by the average closing market price on The New York Stock Exchange (or such other market on which the Company’s Class A common stock is then principally listed) of one share of the Company’s Class A common stock over the trailing 30-day period ending five business days before the effective date of the grant.

The Annual Equity Retainer and Annual Equity Grants are granted in four quarterly installments over the course of the year that commences on the date of each annual meeting of stockholders, with such grants to be made on each September 15, December 15, March 15, and the earlier of (i) June 15 or (ii) the day that is immediately prior to the next subsequent annual meeting of stockholders (each such date, a “Quarterly Date,” and each such grant, a “Quarterly Grant”). The value of each Quarterly Grant shall be equal to the value of the portion of the Annual Equity Retainer and Annual Equity Grants applicable to the period beginning on the day after the immediately preceding Quarterly Date and ending on the then-current Quarterly Date (the “Quarterly Period”), based on the board and committee roles held by the non-employee director during such Quarterly Period. Each Quarterly Grant shall be fully vested upon the date of grant.

21

Initial Equity Grants

Our Non-Employee Director Compensation Policy during fiscal year 2021 provided that, upon initial election to our board of directors, each non-employee director would be granted RSUs having a value of $575,000 (the “Initial Equity Grant”). The Initial Equity Grant vests in equal annual installments over three years, subject to continued service as a director through the applicable vesting dates; provided, however, that if a non-employee director is elected on a date other than at the annual meeting of stockholders, one-third (1/3rd) of such value shall be pro-rated by the amount of time between such election and the next annual meeting of stockholders and such pro-rated portion shall vest on the day prior to the next annual meeting of stockholders, with the other two-thirds (2/3rds) vesting annually over the following two years following such initial vesting date.

During fiscal year 2021, the number of RSUs for the Initial Equity Grant was determined by dividing the applicable value by the average closing market price on The New York Stock Exchange (or such other market on which the Company’s Class A common stock is then principally listed) of one share of the Company’s Class A common stock over the trailing 30-day period ending five business days before the effective date of the grant.

Awards granted under our Non-Employee Director Compensation Policy are subject to full accelerated vesting upon a “sale event,” as defined in our 2016 Stock Option and Incentive Plan (as amended and restated, the “2016 Plan”).

Our Non-Employee Director Compensation Policy also provides that, pursuant to the 2016 Plan, the aggregate amount of compensation, including both equity compensation and cash compensation, paid to any non-employee director in a calendar year will not exceed $750,000 (or such other limit as may be set forth in the 2016 Plan or any similar provision of a successor plan).

We also reimburse all reasonable out-of-pocket expenses incurred by our non-employee directors for their attendance at meetings of our board of directors or any committee thereof.

Changes to Non-Employee Director Compensation effective for Fiscal 2022

Following a review with Compensia of peer company board compensation trends in March 2022, our compensation and talent management committee recommended, and our board of directors approved, the following changes to our non-employee director compensation effective fiscal 2022, targeting non-employee director compensation to the 50^th percentile relative to our peers: (i) increase the annual equity retainer for the lead independent director from $23,000 to $30,000 and (ii) increase the annual equity retainer for all non-employee members of the board of directors from $40,000 to $45,000.

Non-Employee Directors’ Deferred Compensation Program

In July 2017, we implemented a Non-Employee Directors’ Deferred Compensation Program to offer our non-employee directors the ability to defer the receipt of any RSUs granted to them from Initial Grants or Annual Grants under the 2016 Plan. In advance of an award of RSUs and in compliance with the program’s requirements, a non-employee director may elect to defer the receipt of all of his or her RSUs until the earliest of (i) 90 days after such non-employee director ceases to serve as a member of our board of directors; (ii) the consummation of a “sale event”; or (iii) 90 days after the non-employee director’s death (such earliest date, the “Payment Event”). Upon the vesting of the RSUs, any amounts that would otherwise have been paid in shares of Company common stock will be converted into deferred stock units (“DSUs”) on a one-to-one basis and credited to the non-employee director’s deferral account. The DSUs will be paid in shares of Company Class A common stock on a one-to-one basis in a single lump sum (and will cease to be held in the non-employee director’s deferred account) as soon as practicable following the Payment Event.

22

Death Equity Acceleration Policy

See “Executive Compensation—Other Compensation Policies and Practices—Death Equity Acceleration Policy” for a discussion of the treatment of equity awards upon the termination due to death of an employee’s or non-employee director’s employment or other service relationship with the Company or any of its subsidiaries.

Stock Ownership Policy

In April 2018, we adopted a stock ownership policy for our non-employee directors, which was amended and restated in September 2020 and March 2022. Our stock ownership policy, as amended, requires our non-employee directors to acquire and hold a number of shares of our Company’s common stock equal in value to five times (increased from four times in March 2022) the director’s annual retainer for regular service on the board of directors. We only count directly and beneficially owned shares, including shares purchased through our Company’s 2016 Employee Stock Purchase Plan (as amended and restated, the “ESPP”) or Section 401(k) plan, if applicable, and shares underlying vested RSUs that are held or deferred. We do not count shares underlying vested and unexercised in-the-money stock options. Each non-employee director has five years from the later of his or her initial election to the board of directors or from the effective date of the policy to attain the required ownership level.

2021 Non-Employee Director Compensation Table

The following table provides information regarding the total compensation that was earned by or paid to each of our non-employee directors in fiscal year 2021, all of which were paid solely in RSUs. Mr. Lawson, who is our Chief Executive Officer, did not receive any additional compensation for his service as a director. The compensation received by Mr. Lawson, as a named executive officer, is presented in “Executive Compensation—Summary Compensation Table.”

PROPOSAL NO. 1

ELECTION OF DIRECTORS

Our board of directors is currently composed of eight members. In accordance with our amended and restated certificate of incorporation, our board of directors is divided into three staggered classes of directors. At the Annual Meeting, two Class III directors will be elected for a three-year term to succeed the same class whose term is then expiring.

Each director’s term continues until the election and qualification of his or her successor, or such director’s earlier death, resignation or removal. Any increase or decrease in the number of directors will be distributed among the three classes so that, as nearly as possible, each class will consist of one-third of our directors. This classification of our board of directors may have the effect of delaying or preventing changes in the control of our Company.

Nominees

Our nominating and corporate governance committee has recommended, and our board of directors has approved, Donna L. Dubinsky and Deval Patrick as nominees for election as Class III directors at the Annual Meeting. If elected, each of Ms. Dubinsky and Mr. Patrick will serve as Class III directors until the 2025 annual meeting of stockholders and until their successors are duly elected and qualified. Each of the nominees is currently a director of our Company. For information concerning the nominees, please see the section titled “Board of Directors and Corporate Governance.”

If you are a stockholder of record and you sign your proxy card or vote by telephone or over the Internet but do not give instructions with respect to the voting of directors, your shares will be voted “FOR” the election of Ms. Dubinsky and Mr. Patrick. We expect that Ms. Dubinsky and Mr. Patrick will each accept such nomination; however, in the event that a director nominee is unable or declines to serve as a director at the time of the Annual Meeting, the proxies will be voted for any nominee designated by our board of directors to fill such vacancy. If you are a street name stockholder and you do not give voting instructions to your broker or nominee, your broker will leave your shares unvoted on this matter.

Vote Required

The election of directors requires a plurality of the voting power of the shares of our common stock be present virtually or by proxy at the Annual Meeting and entitled to vote thereon to be approved. Abstentions and broker non-votes will have no effect on this proposal. See “Procedural Matters—How many votes are needed for approval of each proposal?” for further information.

Recommendation of the Board of Directors

THE BOARD OF DIRECTORS RECOMMENDS A VOTE “FOR”

EACH OF THE NOMINEES NAMED ABOVE.

PROPOSAL NO. 2

RATIFICATION OF APPOINTMENT OF

INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Our audit committee has appointed KPMG LLP (“KPMG”), an independent registered public accounting firm, to audit our consolidated financial statements for our fiscal year ending December 31, 2022. During our fiscal year ended December 31, 2021, KPMG served as our independent registered public accounting firm.

Notwithstanding the appointment of KPMG, and even if our stockholders ratify the appointment, our audit committee, in its discretion, may appoint another independent registered public accounting firm at any time during our fiscal year if our audit committee believes that such a change would be in the best interests of our Company and our stockholders. At the Annual Meeting, our stockholders are being asked to ratify the appointment of KPMG as our independent registered public accounting firm for our fiscal year ending December 31, 2022. Our audit committee is submitting the appointment of KPMG to our stockholders because we value our stockholders’ views on our independent registered public accounting firm and as a matter of good corporate governance. However, neither the Company’s second amended and restated bylaws nor other governing documents or law require stockholder ratification of the selection of KPMG as the Company’s independent registered public accounting firm. Representatives of KPMG will be present at the Annual Meeting, and they will have an opportunity to make a statement and will be available to respond to appropriate questions from our stockholders.

If our stockholders do not ratify the appointment of KPMG, our audit committee may reconsider the appointment.

Fees Paid to the Independent Registered Public Accounting Firm

The following table presents fees for professional audit services and other services rendered to our Company by KPMG for our fiscal years ended December 31, 2020 and 2021.

Auditor Independence

In our fiscal year ended December 31, 2021, there were no other professional services provided by KPMG, other than those listed above, that would have required our audit committee to consider their compatibility with maintaining the independence of KPMG.

Audit Committee Policy on Pre-Approval of Audit and Permissible Non-Audit Services of Independent Registered Public Accounting Firm

Our audit committee has established a policy governing our use of the services of our independent registered public accounting firm. Under this policy, our audit committee is required to pre-approve all audit, internal control-related services and permissible non-audit services performed by our independent registered public accounting firm in order to ensure that the provision of such services does not impair the public accountants’ independence. All services provided by KPMG for our fiscal years ended December 31, 2020 and 2021 were pre-approved by our audit committee and were compatible with maintaining KPMG’s independence.

Vote Required

The ratification of the appointment of KPMG as our independent registered public accounting firm for our fiscal year ending December 31, 2022 requires the affirmative vote of a majority of the voting power of the shares of our common stock present virtually or by proxy at the Annual Meeting and entitled to vote thereon. Abstentions will have the effect of a vote against this proposal, and broker non-votes will have no effect.

As described in detail under the heading “Executive Compensation—Compensation Discussion and Analysis,” we seek to closely align the interests of our named executive officers with the interests of our stockholders.

Our compensation programs are designed to effectively align our executives’ interests with the interests of our stockholders by focusing on long-term equity incentives that correlate with the growth of sustainable long-term value for our stockholders.

Stockholders are urged to read the section titled “Executive Compensation” and, in particular, the section titled “Executive Compensation—Compensation Discussion and Analysis” in this proxy statement, which discusses how our executive compensation program policies and practices implement our compensation philosophy and contains tabular information and narrative discussion about the compensation of our named executive officers. Our board of directors and our compensation and talent management committee believe that these policies and practices are effective in implementing our compensation philosophy and in achieving our compensation program goals.

The vote on this resolution is not intended to address any specific element of compensation; rather, the vote relates to the compensation of our named executive officers, as described in this proxy statement in accordance with the compensation disclosure rules of the SEC.

Accordingly, we are asking our stockholders to vote on the following resolution at the Annual Meeting:

RESOLVED, that the stockholders hereby approve, on a non-binding advisory basis, the compensation paid to the Company’s named executive officers, as disclosed in the Company’s proxy statement for the 2022 Annual Meeting of Stockholders, pursuant to the compensation disclosure rules of the SEC, including the Compensation Discussion and Analysis, the compensation tables and the narrative discussions that accompany the compensation tables.

Vote Required

The approval of this advisory non-binding proposal requires the affirmative vote of a majority of the voting power of the shares of our common stock present virtually or by proxy at the Annual Meeting and entitled to vote thereon. Abstentions will have the effect of a vote “against” this proposal, and broker non-votes will have no effect.

The vote is advisory, which means that the vote is not binding on the Company, our board of directors or our compensation and talent management committee. To the extent there is any significant vote against our named executive officer compensation as disclosed in this proxy statement, our compensation and talent management committee will evaluate whether any actions are necessary to address the concerns of stockholders.

Recommendation of the Board of Directors

THE BOARD RECOMMENDS THAT YOU VOTE “FOR” THE APPROVAL, ON A NON-BINDING ADVISORY BASIS, OF THE COMPENSATION OF OUR NAMED EXECUTIVE OFFICERS, AS DISCLOSED IN THIS PROXY STATEMENT.

The audit committee reviews and assesses the audit committee’s performance and the adequacy of its charter on an annual basis.

With respect to our financial reporting process, our management is responsible for (1) establishing and maintaining internal controls and (2) preparing our consolidated financial statements.

It is the responsibility of the audit committee to oversee these activities. It is not the responsibility of the audit committee to prepare our financial statements. These are the fundamental responsibilities of management. In the performance of its oversight function, the audit committee has:

Based on the audit committee’s review and discussions with management and KPMG, the audit committee recommended to the board of directors that the audited financial statements be included in the Annual Report on Form 10-K for the fiscal year ended December 31, 2021.

This Compensation Discussion and Analysis describes the material elements of our executive compensation program during 2021 and certain aspects of our compensation program for 2022. It also provides an overview of our executive compensation philosophy and objectives. Finally, it discusses how our compensation and talent management committee of our board of directors arrived at the specific compensation decisions for our executive officers, including our named executive officers, for 2021, including the key factors that our compensation and talent management committee considered in determining their compensation.

Executive Summary

Business Overview

Twilio spent over a decade building the leading cloud communications platform, but communications is just the beginning. Twilio’s vision is to become the leading customer engagement platform, ultimately providing businesses with the holy grail—a single view of the customer journey and the ability to take action, delivering real-time, personalized communications. We believe the future of customer engagement will be written in software by the developers of the world—our customers.

Cloud platforms are a category of software that enable developers to build and manage applications without the complexity of creating and maintaining the underlying infrastructure. These platforms have arisen to enable a fast pace of innovation across a range of categories, such as computing and storage. As the leader in the cloud communications platform category, we enable developers to build, scale and operate real-time customer engagement within software applications.

We offer a customer engagement platform with software designed to address specific use cases, like account security and contact centers, and a set of Application Programming Interfaces (“APIs”) that handles the higher-level communication logic needed for nearly every type of customer engagement. These APIs are focused on the business challenges that a developer is looking to address, allowing our customers to more quickly and easily build better ways to engage with their customers throughout their journey. Our engagement platform also includes a set of APIs that enable developers to embed voice, messaging, video

32

and email capabilities into their applications, and are designed to support almost all the fundamental ways humans communicate, unlocking innovators to address just about any communication market. The Super Network is our software layer that allows our customers’ software to communicate with connected devices globally. It interconnects with communications networks and inbox service providers around the world and continually analyzes data to optimize the quality and cost of communications that flow through our platform. The Super Network also contains a set of APIs giving our customers access to more foundational components of our platform, like phone numbers and session initiation protocol (“SIP”) Trunking.

Our overall strategy is to develop great APIs that developers love. These developers are our champions and bring us “in” to companies of every type, most frequently utilizing our messaging and email tools as an entry point. This “in” motion creates initial relationships with customers of all sizes including major enterprises that allow us to move “up” the software stack and provide those companies with software solutions that address their customer engagement requirements from marketing to sales and support. Today, we offer Twilio Campaigns for marketing, Twilio Flex for customer support and Twilio Verify to onboard and recognize customers. The more strategic nature of these software products also allows us to move up the organization chart, interacting with more senior and strategic purchasers. This “in” and “up” strategy is a motion we work on improving every day. We will also continue to invest aggressively in our platform approach, which prioritizes increasing our reach and scale.

Fiscal 2021 Performance Highlights

In 2021, we continued to grow revenue and diversify our business, both internationally and across different customer sizes, and we achieved the following significant financial and operational results:

Please refer to Appendix A of this proxy statement for a more detailed discussion of how we measure Active Customer Accounts and other key business metrics and for a reconciliation of GAAP loss from operations to non-GAAP income (loss) from operations.

Fiscal 2021 Executive Compensation Highlights

Based on our overall operating environment and these results, our compensation and talent management committee took the following key actions with respect to the compensation of our named executive officers for 2021:

33

Fiscal 2021 Executive Transitions

Mr. Shipchandler was appointed Chief Operating Officer effective October 27, 2021. Prior to that time, Mr. Shipchandler served as our Chief Financial Officer. Also effective October 27, 2021, Mr. Boroditsky assumed an expanded role in his position as Chief Revenue Officer and subsequently became an executive officer.

Mr. Manor joined as Chief Product Officer as of November 15, 2021. Mr. Chew, our former Chief Product Officer, ceased to be employed by us as of May 17, 2021.

Mr. Wagner joined as Chief Legal Officer on December 13, 2021. Karyn Smith, our former General Counsel, ceased to be an executive officer as of December 15, 2021, but remained an employee of the Company until January 7, 2022.

Mr. Hu resigned as our Chief Operating Officer as of October 27, 2021. Following his resignation, Mr. Hu remained as a strategic advisor until January 3, 2022.

Pay-for-Performance Analysis

We believe our executive compensation program is reasonable and competitive, and appropriately balances the goals of attracting, motivating, rewarding and retaining our executive officers with the goal of aligning their interests with those of our stockholders. The annual compensation of our executive officers, including our named executive officers, varies from year to year based on our corporate financial and operational results and individual performance. While we do not determine either contingent (“variable”) or “fixed” pay for each named executive officer with reference to a specific percentage of target total direct compensation, consistent with our “pay-for-performance” philosophy, our executive compensation program heavily emphasizes “variable” pay over “fixed” pay.

34

In 2021, the majority of the target total direct compensation of our Chief Executive Officer consisted of variable pay in the form of long-term incentive compensation opportunities. Fixed pay, primarily consisting of base salary, made up only 1% of our Chief Executive Officer’s target total direct compensation, while variable pay, consisting of long-term incentive compensation in the form of equity awards, made up the remaining 99% of his target total direct compensation. Similar allocations applied to our other executive officers, including each of our other named executive officers. The following charts show the percentages of target variable pay versus target fixed pay for our Chief Executive Officer and our other named executive officers in 2021:

We believe that this approach provides balanced incentives for our executive officers to drive our financial performance and create long-term stockholder value.

Executive Compensation Policies and Practices

We endeavor to maintain sound governance standards consistent with our executive compensation policies and practices. Our compensation and talent management committee evaluates our executive compensation program on at least an annual basis to ensure that it is consistent with our short-term and long-term goals given the dynamic nature of our business and the market in which we compete for executive talent. The following summarizes our executive compensation and related policies and practices:

35

Annual Say-on-Pay Vote on Executive Compensation

Our board of directors has elected to hold an advisory vote on executive compensation on an annual basis (the “Say-on-Pay Vote”), thereby giving our stockholders the opportunity to provide feedback on the compensation of our named executive officers each year. As reported in our current report on Form 8-K filed with the SEC on June 16, 2021, approximately 73% of the votes cast on the proposal expressed support for the compensation program offered to our named executive officers as disclosed in last year’s proxy statement. We will be conducting our annual Say-on-Pay Vote as described in Proposal No. 3 of this

36

proxy statement at the 2022 Annual Meeting of Stockholders. The next Say-on-Pay Vote will be held at our 2023 Annual Meeting of Stockholders.

Commitment to Stockholder Engagement

As we manage our business with a focus on continued innovation and growth, we recognize that our compensation program must balance stockholder perspectives with our ability to retain and attract the highest caliber of talent to help facilitate growth at scale. Our board of directors and our compensation and talent management committee value the stockholder perspectives we receive, through direct engagement as well as through voting decisions, including our annual Say-on-Pay Vote at our annual stockholder meetings, and the compensation-related feedback we receive from stockholders is an important component that informs the compensation and talent management committee’s decision-making process when reviewing our executive compensation programs each year.

We have established a robust stockholder engagement program to help us better understand the perspectives of our stockholders. In 2021, in addition to our standard engagement with stockholders throughout the year, we conducted meetings with several of our large stockholders, with participation from our management team and certain members of our board of directors, including Ms. Rottenberg, the chairperson of our nominating and corporate governance committee, and, until her resignation from our board of directors, Ms. Donio, the former chairperson of our compensation and talent management committee on topics ranging from compensation strategy, to environmental, social and governance matters (“ESG”), including board structure and corporate governance. In addition, our head of investor relations regularly communicates stockholder feedback to senior management and the board of directors for consideration in their decision making.

The 2021 executive compensation program was implemented in early 2021, and the compensation and talent management committee, in connection with input from our full board of directors, determined at that time that our concentration on equity compensation, particularly the grant of equity awards in the form of 50% (by fair value) stock options and 50% (by fair value) RSUs with time-based vesting, is aligned with long-term stockholder value. However, our compensation and talent management committee continues to assess the Company’s equity compensation practices in light of the Company’s continued growth and maturation as well as discussions with stockholders and determined to implement changes to our executive compensation program beginning in 2022 to grant performance-based equity awards as part of our executive compensation program, as discussed in “Evolving our Executive Compensation Program” below.

We believe the addition of performance-based equity awards, as well as other enhancements to our governance practices and disclosures in response to stockholder feedback, such as increasing our stock ownership requirements for directors and executive offices and enhancing our ESG disclosures, have advanced our compensation practices and governance in a manner that both benefits stockholders and continues to align with our strategy and pay philosophy.

Executive Compensation Philosophy

We operate in an extremely competitive market where there is substantial and continuous competition for leadership with the experience and skill to lead in a dynamic and innovative industry. Our executive compensation program is guided by our overarching philosophy of paying for demonstrable performance and aligning the compensation of our executive officers with the long-term interests of our stockholders. Consistent with this philosophy, we designed our executive compensation program to achieve the following primary objectives:

37

Because we do not have a cash bonus program for our executive officers, generally, our compensation and talent management committee has sought to set base salaries at the higher end of the competitive market range to provide what it believes to be reasonable cash compensation levels and will serve to attract and retain our executive officers. Further, our compensation and talent management committee tends to weight the target total direct compensation opportunities of our executive officers more heavily towards equity compensation. We understand the importance of linking the individual performance of our executive officers and the financial and operational performance of our company to our overall executive compensation program. We believe our strong focus on, and heavy weighting toward, equity compensation supports that philosophy and has worked to align our executive compensation with the interests of our stockholders. However, we continue to review the current equity compensation trends as well as the feedback from our stockholders in regard to our executive compensation program.

Evolving our Executive Compensation Program

In March 2022, in addition to granting time-based restricted stock unit awards to our named executive officers, our compensation and talent management committee also granted performance-based restricted stock unit awards. The performance-based awards vest based on the achievement of certain goals over specified performance periods, including year-over year organic revenue growth rates and non-GAAP operating profit, and are intended to further align the interests of our named executive officers and our stockholders.

Oversight of Executive Compensation Program

Role of the Compensation and Talent Management Committee

Our compensation and talent management committee discharges many of the responsibilities of our board of directors relating to the compensation of our executive officers, including our named executive officers, and the non-employee members of our board of directors (as described further in “Board of Directors and Corporate Governance—Non-Employee Director Compensation” above). Our compensation and talent management committee has overall responsibility for overseeing our compensation structure, policies and programs generally, and overseeing and evaluating the compensation plans, policies and practices applicable to our executive officers. Our compensation and talent management committee also oversees the annual evaluation of our executive officers, including our named executive officers, for the prior fiscal year and has the authority to retain, and has retained, an independent compensation consultant to provide support to the committee in its review and assessment of our compensation programs.

Compensation-Setting Process

Our compensation and talent management committee determines the target total direct compensation opportunities for our executive officers, including our named executive officers. Our compensation and talent management committee does not use a single method or measure in developing its recommendations, nor does it establish one specific target for the total direct compensation opportunities of our executive officers. Rather, it retains flexibility to pay our executive officers within certain ranges. Nonetheless, our compensation and talent management committee generally begins its deliberations on cash and equity compensation levels with reference to various percentile levels for cash compensation and target total direct compensation as reflected in competitive market data, with an intended result of weighting compensation more heavily towards equity compensation.

38

When formulating its recommendations for the amount of each compensation element and approving each compensation element and the target total direct compensation opportunity for our executive officers, our compensation and talent management committee considers the following factors:

These factors provide the framework for compensation decision-making and final decisions regarding the compensation opportunity for each executive officer. No single factor is determinative in setting pay levels, nor was the impact of any factor on the determination of pay levels quantifiable. Our compensation and talent management committee reviews the base salary levels and long-term incentive compensation opportunities of our executive officers, including our named executive officers, each fiscal year at the beginning of the year, or more frequently as warranted. Long-term incentive compensation is granted on a regularly-scheduled basis, as described in “Other Compensation Policies and Practices—Equity Awards Grant Policy” below.

Role of Chief Executive Officer

In discharging its responsibilities, our compensation and talent management committee consults with members of our management, including our Chief Executive Officer. Our management assists our compensation and talent management committee by providing information on corporate and individual performance, market compensation data and management’s perspective on compensation matters. Our compensation and talent management committee solicits and reviews our Chief Executive Officer’s recommendations and proposals with respect to adjustments to annual cash compensation, long-term incentive compensation opportunities, program structures and other compensation-related matters for our executive officers, other than with respect to his own compensation.

Our compensation and talent management committee reviews and discusses these recommendations and proposals with our Chief Executive Officer and considers them as one factor in determining the compensation for our executive officers, including our other named executive officers. Our Chief Executive Officer recuses himself from all deliberations and determinations regarding his own compensation.

39

Role of Compensation Consultant

Our compensation and talent management committee engages an external independent compensation consultant to assist it by providing information, analysis and other advice relating to our executive compensation program and the decisions resulting from its annual executive compensation review. For 2021, our compensation and talent management committee engaged Compensia as its compensation consultant to advise on executive compensation matters, including competitive market pay practices for our executive officers, the selection of our compensation peer group, and data analysis. For 2021, the scope of Compensia’s engagement included:

The terms of Compensia’s engagement included reporting directly to our compensation and talent management committee and to our compensation and talent management committee chairperson. Compensia also coordinated with our management for data collection and job matching for our executive officers and provided data and analyses in connection with the review of our equity strategy. In 2021, Compensia did not provide any other services to us. In March 2021, our compensation and talent management committee evaluated Compensia’s independence pursuant to NYSE and LTSE Listing Standards and the relevant SEC rules and determined that no conflict of interest had arisen as a result of the work performed by Compensia.

Use of Market Data

For purposes of comparing our executive compensation against the competitive market, our compensation and talent management committee reviews and considers the compensation levels and practices of a group of peer companies. This compensation peer group consists of technology companies that are similar to us in terms of industry, revenue and market capitalization.

Our compensation and talent management committee reviews our compensation peer group at least annually and makes adjustments to its composition if warranted, taking into account changes in both our business and the businesses of the companies in the peer group, and input from its compensation consultant. Accordingly, the peer group that was used for comparative purposes for 2021 was approved in September 2020.

40

In developing the compensation peer group for 2021, the following criteria were evaluated in identifying comparable companies:

In September 2020, the compensation and talent management committee reviewed our compensation peer group and, upon the recommendation of its compensation consultant, added Ansys, Coupa Software, Fortinet, Intuit, Synopsys and The Trade Desk to the compensation peer group and removed Dropbox, Guidewire Software, Hubspot, New Relic, Paylocity Holding, Proofpoint and Zendesk. The peer group for 2021, which was approved by the compensation and talent management committee in September 2020, consisted of the following companies:

Our compensation and talent management committee uses data drawn from our compensation peer group, as well as data from the Radford Global Technology executive compensation survey (the “Radford Survey”), to evaluate the competitive market when formulating its recommendation for the total direct compensation packages for our executive officers, including base salary and long-term incentive compensation opportunities. The Radford Survey provides compensation market intelligence and is widely used within the technology industry.

In addition, subsets of the Radford Survey were incorporated into the competitive assessment prepared by Compensia and used by our compensation and talent management committee to evaluate the compensation of our executive officers. Specifically, our compensation and talent management committee received a custom report of survey results reflecting only companies from our compensation peer group in addition to survey results tailored solely based on revenue. The Radford Survey data supplements the compensation peer group data and provides additional information for our named executive officers and other executive positions for which there is less comparable public data available.

41

Individual Compensation Elements

In 2021, the principal elements of our executive compensation program, and the purposes for each element, were as follows:

Base Salary

Base salary represents the fixed portion of the compensation of our executive officers, including our named executive officers, and is an important element of compensation intended to attract and retain highly talented individuals.

Using the competitive market data provided by its compensation consultant, our compensation and talent management committee reviews and develops recommendations for adjusting the base salaries for each of our executive officers, including our named executive officers, as part of its annual executive compensation review. In addition, the base salaries of our executive officers may be adjusted by our compensation and talent management committee in the event of a promotion or significant change in responsibilities.

Generally, our compensation and talent management committee sets base salaries with reference to various percentile levels of the competitive range of our compensation peer group and applicable executive compensation survey data. Since our initial public offering, we have evaluated the base salaries of our executive officers in the context of establishing their total cash compensation at levels that are consistent with the target total cash compensation of executive officers holding comparable positions at public companies.

In 2021, consistent with the recommendation of our Chief Executive Officer, our compensation and talent management committee determined to increase the base salaries of our executive officers other than our Chief Executive Officer. In making these decisions, our compensation and talent management committee considered the current risks and challenges facing our company, our decision to forego the adoption of an annual cash bonus program, its objective of gradually positioning the target total cash compensation of our executive officers at levels that are more consistent with those of a public company in our industry, as well as the factors described in “Oversight of Executive Compensation Program—Compensation-Setting Process” above. We recognize that our Chief Executive Officer’s base salary is significantly lower than the peer group median, despite his success in the role and our willingness to pay him a market-based salary. However, at our Chief Executive Officer’s request to weight more of his target total direct compensation to variable pay in the form of long-term incentive compensation, our compensation and talent management committee determined to maintain his base salary at its 2019 and 2020 levels, other than a nominal increase for rounding purposes.

42

The base salaries of our named executive officers for 2020 and 2021 (effective January 1, 2021) were as follows:

The actual base salaries paid to our named executive officers in 2021 are set forth in the “Summary Compensation Table” below.

Cash Incentives

As our Chief Revenue Officer, Mr. Boroditsky’s responsibilities are focused on sales and his compensation includes participation in our sales commission plan (the “Sales Commission Plan”) with terms that are aligned with the results achieved by our global sales team.

For fiscal 2021, after considering competitive market data in consultation with a leading third-party consultancy for sales compensation, Mr. Boroditsky’s commission opportunity for fiscal 2021 was determined to be equal to 100% of his annual base salary, consistent with his opportunity for the prior fiscal year. The Sales Commission Plan is designed to reward Mr. Boroditsky based on annual performance of total estimated annual recurring revenue (“eARR”), software eARR and company revenue metrics, paid monthly. Mr. Boroditsky’s monthly payouts are based on performance against the annual target, additive,

43

with no cap. The performance target levels for Mr. Boroditsky were designed to be challenging to achieve. The Sales Commission Plan and performance criteria are evaluated annually with an eye to reducing risks while appropriately incentivizing performance.

Long-Term Incentive Compensation

We view long-term incentive compensation in the form of equity awards as a critical element of our executive compensation program. The realized value of these equity awards bears a direct relationship to our stock price, and, therefore, these awards are an incentive for our executive officers, including our named executive officers, to create value for our stockholders. Equity awards also help us retain qualified executive officers in a competitive market.

Long-term incentive compensation opportunities in the form of equity awards are granted by our compensation and talent management committee on a regularly-scheduled basis, as described in “Other Compensation Policies and Practices—Equity Awards Grant Policy” below. The amount and forms of such equity awards are determined by our compensation and talent management committee after considering the factors described in “Oversight of Executive Compensation Program—Compensation-Setting Process” above. The amounts of the equity awards are also intended to provide competitively-sized awards and resulting target total direct compensation opportunities that are competitive with the compensation opportunities offered by the companies in our compensation peer group and Radford Survey data for similar roles and positions for each of our executive officers, taking into consideration the factors described in “Oversight of Executive Compensation Program—Compensation-Setting Process” above.

In 2021, our compensation and talent management committee determined that the equity awards to be granted to our executive officers should be in the form of time-based stock options to purchase shares of our Class A common stock and time-based RSUs that may be settled for shares of our Class A common stock. Our compensation and talent management committee determined to grant equity awards in the form of 50% (by fair value) stock options and 50% (by fair value) time-based RSUs. Stock options only have value if our stock price appreciates above the exercise price thereof. Both stock options and RSUs have retention value over the vesting period. In determining the size of the individual grants to our executive officers, our compensation and talent management committee considered the factors described in “Oversight of Executive Compensation Program—Compensation-Setting Process” above, with emphasis on our exceptional growth in size and revenue during 2020. In addition, our compensation and talent management committee focused on the fact that many of our executive officers are in high demand in the market due, in part, to our excellent performance in 2020. Therefore, our compensation and talent management committee considered how best to retain our talent. In determining the size of the equity grants made to our Chief Executive Officer, the compensation and talent management committee also factored in Mr. Lawson’s relatively low base salary.

After consideration of these factors, our compensation and talent management committee determined to grant equity awards to our executive officers with a value in the range of the 70^th percentile to the 85^th percentile of our peer group range. Our compensation and talent management committee determined that the value of these awards was appropriate and necessary to sufficiently reward exceptional performance, to motivate our executive officers for continued effort to create value for our stockholders and to help ensure retention in a competitive market. Importantly, our compensation and talent management committee also determined to maintain the prior deviation from the historic vesting schedules for executive awards to balance the magnitude of the awards, and also to motivate long-term retention and team stability. Therefore, the stock options and RSUs granted to our executive officers in February 2021 vest over four years with 33% vesting in equal quarterly installments between the first and second anniversaries of the vesting commencement date of December 31, 2020, 33% vesting in equal quarterly installments between the second and third anniversaries of the vesting commencement date of December 31, 2020 and 34% vesting in equal quarterly installments between the third and fourth anniversaries of the vesting commencement date of December 31, 2020, subject to the executive’s

44

continued employment with us. In addition to the February 2021 grants, our compensation and talent management committee also granted equity awards to certain executive officers in 2021 in connection with new hires and promotions with specific vesting schedules, as described further in “Executive Compensation—Additional Executive Officer Awards” and “Executive Compensation—Grants of Plan-Based Awards Table” below.

After considering the factors described in “Oversight of Executive Compensation Program—Compensation-Setting Process” above, our compensation and talent management committee approved the following equity awards in February 2021 for our then-existing named executive officers in 2021 as part of its annual executive compensation review:

Additional Executive Officer Awards

Mr. Manor received a (1) one-time stock option award with a grant date fair value of $8,098,119 and (2) one-time restricted stock units award with a grant date fair value of $33,687,986 in connection with his commencement of employment with us in November 2021. The shares subject to the option vest over four years in equal monthly installments, and the RSUs vest over four years, with 1/16th of the RSUs vesting on February 15, 2022 and the remaining RSUs vesting in equal quarterly installments, in each case subject to continued employment with us.

Mr. Boroditsky received a (1) one-time stock option award with a grant date fair value of $5,158,566 and (2) one-time restricted stock units award with a grant date fair value of $5,131,560 in connection with his expanded role in his position as Chief Revenue Officer in October 2021. The shares subject to this

45

option vest in 24 equal monthly installments, and the RSUs vest over two years, with 1/8th of the RSU vesting on November 15, 2021 and the remaining RSUs vesting in equal quarterly installments, in each case subject to continued employment with us. On April 28, 2022, Mr. Boroditsky notified us of his intention to resign from his position as Chief Revenue Officer, effective immediately. Mr. Boroditsky’s last day of employment will be August 19, 2022 and the unvested portion of his stock option and RSUs will cease vesting and be cancelled as of such date.

Mr. Shipchandler also received (1) a one-time stock option award with a grant date fair value of $2,303,576 and (2) a one-time restricted stock unit award with a grant date fair value of $2,231,126 in connection with this appointment as Chief Operating Officer, with vesting schedules consistent with his February 2021 awards. Mr. Wagner commenced employment with us in December 2021 and did not receive any equity awards in fiscal 2021, but was granted a new hire RSU award in January 2022 in accordance with his employment offer letter. Please see “Summary Compensation Table,” “Grants of Plan-Based Awards Table” and “Employment Agreements or Offer Letters with Named Executive Officers” below for additional information.

Stock Options

We believe that stock options provide a strong reward for growth in the market price of our common stock as their entire value depends on future stock price appreciation, as well as a strong incentive for our executive officers to remain employed with our Company as they require continued service to our Company through the vesting period. In 2021, the stock options to purchase shares of our Class A common stock that were granted by our compensation and talent management committee generally had a 10-year term. To balance retention and incentive dynamics for the stock option grants made in February 2021, the vesting schedule for such grants were set as follows: 33% of the shares subject to the stock option vest in equal quarterly installments between the first and second anniversaries of the “vesting commencement date” (December 31, 2020), 33% of the shares subject to the stock option vest in equal quarterly installments between the second and third anniversaries of the vesting commencement date and 34% of the shares subject to the stock option vest in equal quarterly installments between the third and fourth anniversaries of the vesting commencement date, subject to continued employment through each such vesting date. The options subject to Mr. Borodistky’s October 2021 grant expire three years from the date of his separation from service due to termination by the company without Cause or by Mr. Boroditsky for Good Reason, as those terms are defined in the Boroditsky Letter (as defined below), or 10 years from the date of the grant, whichever comes first.

Stock options granted by our compensation and talent management committee to newly-hired executives generally have had a 10-year term and generally vested as to 25% of the shares subject to the stock option on the first anniversary of the employment commencement date and 1/48^th of the shares subject to the stock option each month thereafter for the following three years, subject to continued service through each such vesting date. Effective February 1, 2022, and applicable retrospectively to affected employees, stock options previously granted to our executive officers vest in equal monthly installments from the applicable vesting commencement date, subject to the executive’s continued employment with us. Please see “Summary Compensation Table” and “Grants of Plan-Based Awards Table” below for additional information.

Time-Based RSUs

We believe time-based RSUs also provide a strong retention incentive for our executive officers, provide a moderate reward for growth in the value of our Class A common stock and, because they use fewer shares than stock options, are less dilutive to our stockholders. In 2021, similar to the stock option grants, in order to balance retention and incentive dynamics for the time-based RSU grants that may be settled in shares of our Class A common stock, the vesting schedule for such grants were set as follows: 33% of the shares subject to the award vest in equal quarterly installments between the first and second anniversaries of the “vesting commencement date” (December 31, 2020), 33% of the shares subject to the

46

award vest in equal quarterly installments between the second and third anniversaries of the vesting commencement date and 34% of the shares subject to the award vest in equal quarterly installments between the third and fourth anniversaries of the vesting commencement date, subject to continued employment through each such vesting date.

Time-based RSUs that may be settled in shares of our Class A common stock that were granted by our compensation and talent management committee to newly-hired executives generally vested as to 25% of the shares subject to the award on the first anniversary of the first August 15, November 15, February 15 or May 15 to occur following the employment commencement date and 1/16^th of the shares subject to the award each quarter thereafter for the following three years, subject to continued employment through each such vesting date. Effective February 1, 2022, and applicable retrospectively to affected employees, RSUs granted to new executive officers vest in equal quarterly installments from the applicable vesting commencement date, subject to the executive’s continued employment with us.

The equity awards granted to our named executive officers in 2021 are set forth in the “Summary Compensation Table” and the “Grants of Plan-Based Awards Table” below.

Health and Welfare Benefits

Our executive officers, including our named executive officers, are eligible to receive the same employee benefits that are generally available to all of our full-time employees, subject to the satisfaction of certain eligibility requirements. These benefits include our medical, dental and vision insurance and life and disability insurance plans. In structuring these benefit plans, we seek to provide an aggregate level of benefits that are comparable to those provided by similar companies.

In addition, we maintain a tax-qualified Section 401(k) retirement plan that provides eligible U.S. employees with an opportunity to save for retirement on a tax-advantaged basis. Plan participants are able to defer eligible compensation subject to the applicable annual limits set forth in the Internal Revenue Code of 1986, as amended (the “Code”). In 2021, we matched 50% of the first 6% of contributions by plan participants, subject to annual contribution limits set forth in the Code. We have the ability to make discretionary contributions to the Section 401(k) plan but have not done so to date. The Section 401(k) plan is intended to be qualified under Section 401(a) of the Code with the plan’s related trust intended to be tax exempt under Section 501(a) of the Code. As a tax-qualified retirement plan, contributions to the Section 401(k) plan and earnings on those contributions are not taxable to the employees until distributed from the Section 401(k) plan.

Perquisites and Other Personal Benefits

Currently, we do not view perquisites or other personal benefits as a significant component of our executive compensation program. Accordingly, we do not provide significant perquisites or other personal benefits to our executive officers, including our named executive officers, except as generally made available to our employees, or in situations where we believe it is appropriate to assist an individual in the performance of his or her duties, to award long-standing service to us, to make our executive officers more efficient and effective and for recruitment and retention purposes.

During 2021, none of our named executive officers received perquisites or other personal benefits that were, in the aggregate, $10,000 or more for each individual, except for Mr. Lawson, our Chief Executive Officer, for whom we paid $3,350 for our matching contributions to his Section 401(k) account in 2021, and his $280,000 filing fee under HSR, as well as $5,595 and $275,335, respectively, for the related legal fees and tax gross-up. We believe that reimbursing our Chief Executive Officer for the HSR filing fee and its related legal fees and tax consequences was consistent with our decision to continue to compensate him almost entirely through equity-compensation arrangements. Absent this regulatory filing, our Chief Executive Officer would not be able to participate in our long-term incentive compensation program and, therefore, we determined that it was appropriate for us to reimburse him for this filing fee and any related tax liabilities.

47

In the future, we may provide perquisites or other personal benefits in limited circumstances. All future practices with respect to perquisites or other personal benefits will be approved and subject to periodic review by our compensation and talent management committee.

Post-Employment Compensation Arrangements

We believe that having in place reasonable and competitive post-employment compensation arrangements are essential to attracting and retaining highly qualified executive officers. In connection with our initial public offering in 2016, we adopted an executive severance plan (as amended and restated in June 2017, the “Amended and Restated Executive Severance Plan”) to provide more standardized severance payments and benefits to our executive officers. In March 2018, we divided our Amended and Restated Executive Severance Plan into three separate plans, which we further amended in March 2022. Our three plans currently apply to our Chief Executive Officer (the “CEO Severance Plan”), our key executive officers and senior vice-president level employees (the “Key Executive Severance Plan”, together with our CEO Severance Plan, the “Executive Severance Plans”) and our vice president-level employees (the “VP Severance Plan”). Our Chief Executive Officer participates in the CEO Severance Plan and our other named executive officers participate in the Key Executive Severance Plan.

The Executive Severance Plans, as discussed in more detail in “Potential Payments Upon Termination or Change in Control—Executive Severance Plans” below are designed to help ensure the continued service of key executive officers in the event of a potential acquisition, to provide reasonable compensation to executive officers who leave our employ under specified circumstances and to align the interests of our executive officers and our stockholders when considering our long-term future.

We believe that the severance payments and benefits provided to our executive officers under the Executive Severance Plans are appropriate in light of the post-employment compensation protections available to similarly-situated executive officers at companies in our compensation peer group and are an important component of each executive officer’s overall compensation as they help us to attract and retain our key executives who could have other job alternatives that may appear to them to be more attractive absent these protections.

We also believe that the occurrence or potential occurrence of a change in control transaction will create uncertainty regarding the continued employment of our executive officers. In order to encourage them to remain employed with us during an important time when their prospects for continued employment following the transaction are often uncertain, we provide our executive officers with the opportunity to receive additional severance protections during a change in control protection period. In addition, we provide additional payment and benefit protections if an executive officer voluntarily terminates employment with us for good reason in connection with a change in control of our Company, because we believe that a voluntary termination of employment for good reason is essentially equivalent to an involuntary termination of employment by us without cause. The primary purpose of these arrangements is to keep our most senior executive officers focused on pursuing potential corporate transactions that are in the best interests of our stockholders regardless of whether those transactions may result in their own job loss. Reasonable post-acquisition payments and benefits should serve the interests of both the executive officer and our stockholders.

To protect our Company’s interests, we require all participants of the Executive Severance Plans to sign a standard form of general release in favor of the Company prior to receiving any severance payments or benefits under the applicable plan.

In addition, under the Executive Severance Plans, all payments and benefits provided in the event of a change in control of the Company are payable only if there is a qualifying loss of employment by a named executive officer (commonly referred to as a “double-trigger” arrangement). In the case of the acceleration of vesting of outstanding equity awards, we use this double-trigger arrangement to protect against the loss of retention value following a change in control of the Company and to avoid windfalls, both of which could occur if the vesting of equity awards accelerated automatically as a result of the transaction.

48

We do not provide excise tax payments (or “gross-ups”) relating to a change in control of our Company and have no such obligations in place with respect to any of our named executive officers.

For detailed descriptions of the post-employment compensation arrangements we maintain with our named executive officers, as well as an estimate of the potential payments and benefits payable to our named executive officers under their post-employment compensation arrangements, see “Employment Agreements or Offer Letters with Named Executive Officers” and “Potential Payments Upon Termination or Change in Control” below.

Other Compensation Policies and Practices

Equity Awards Grant Policy

Under our Amended and Restated Equity Award Grant Policy, we generally grant equity awards on a regularly scheduled basis to enhance the effectiveness of our internal control over our equity award grant process and to alleviate several of the burdens related to accounting for such equity awards, as follows:

49

Death Equity Acceleration Policy

In December 2020, the compensation and talent management committee approved a policy providing that upon the termination due to death of an employee’s or non-employee director’s employment or other service relationship with the Company or any of its subsidiaries, any then outstanding equity awards held by the individual that vest solely based on continued employment or service will automatically receive two years of supplemental vesting. The policy applies both to awards granted prior to the adoption of the policy, as well as awards granted thereafter.

Policy Prohibiting Hedging and Pledging of Equity Securities

Our Amended and Restated Insider Trading Policy prohibits our employees, including our executive officers, and the non-employee members of our board of directors from engaging in any short sale and from buying or selling puts, calls, other derivative securities or any derivative securities that provide the economic equivalent of ownership of any of our securities or an opportunity, direct or indirect, to profit from any change in the value of our securities or engage in any other hedging transaction with respect to our securities, at any time. In addition, our Insider Trading Policy prohibits our employees, including our executive officers, and the non-employee members of our board of directors from using our securities as collateral in a margin account or from pledging our securities as collateral for a loan. Mr. Chew, our former Chief Product Officer, ceased to be employed by us as of May 17, 2021 and entered into pledging arrangements after his employment ceased with us.

Stock Ownership Policy

To further align the interests of our executive officers with those of our stockholders and to promote a long-term perspective in managing our Company, in April 2018, we adopted a stock ownership policy for our Chief Executive Officer and executive officers subject to Section 16 of the Exchange Act (“Section 16 Officers”), including each of our named executive officers. We amended and restated this stock ownership policy in September 2020 and in March 2022. In March 2022, we revised the stock ownership policy to, among other things, increase the salary-multiple for our named executive officers (other than our Chief Executive Officer) from one time to three times his or her annual base salary, eliminate pre-established share number thresholds, and eliminate vested but unexercised in-the-money options from the share ownership calculation.

Our stock ownership policy, as amended, requires each named executive officer to acquire and hold a number of shares of our common stock equal in value to a multiple of such named executive officer’s annual base salary until he or she ceases to be our Chief Executive Officer or a Section 16 Officer, as applicable. The multiple for our Chief Executive Officer is six times his annual base salary and the multiple for our other named executive officers is three times his or her annual base salary. For purposes of our stock ownership policy, we only count directly and beneficially owned shares, including shares purchased through our ESPP or Section 401(k) Plan, if applicable, and shares underlying vested RSUs that are held or deferred. Each named executive officer has five years from the later of his or her designation as our Chief Executive Officer or Section 16 Officer, as applicable, or from the original effective date of the policy to obtain the required ownership level.

Compensation Recovery Policy

We intend to adopt a compensation recovery (“clawback”) policy once the SEC adopts final rules implementing the requirement of Section 954 of the Dodd-Frank Wall Street Reform and Consumer Protection Act.

50

Tax and Accounting Considerations

Deductibility of Executive Compensation

Under Section 162(m) of the Internal Code (“Section 162(m)”), compensation paid to each of the Company’s “covered employees” that exceeds $1 million per taxable year is generally non-deductible. Although our compensation and talent management committee will continue to consider tax implications as one factor in determining executive compensation, it also looks at other factors in making its decisions and retains the flexibility to provide compensation for our executive officers in a manner consistent with the goals of our executive compensation program and the best interests of our stockholders, which may include providing for compensation that is not deductible by us due to the deduction limit under Section 162(m).

Taxation of “Parachute” Payments

Sections 280G and 4999 of the Code provide that executive officers and directors who hold significant equity interests and certain other service providers may be subject to significant additional taxes if they receive payments or benefits in connection with a change in control of the Company that exceeds certain prescribed limits, and that the Company (or a successor) may forfeit a deduction on the amounts subject to this additional tax. We have not agreed to provide any executive officer, including any named executive officer, with a “gross-up” or other reimbursement payment for any tax liability that the executive officer might owe as a result of the application of Sections 280G or 4999 of the Code.

Section 409A of the Internal Revenue Code

Section 409A of the Code imposes additional significant taxes in the event that an executive officer, director or service provider receives “deferred compensation” that does not satisfy the requirements of Section 409A of the Code. Although we do not maintain a traditional nonqualified deferred compensation plan for our executive officers, Section 409A of the Code does apply to certain severance arrangements, bonus arrangements and equity awards, and we have structured all such arrangements and awards in a manner to either avoid or comply with the applicable requirements of Section 409A of the Code. For our non-employee directors, we provide a Non-Employee Directors’ Deferred Compensation Program, which has been structured to comply with the applicable requirements of Section 409A of the Code.

Accounting for Stock-Based Compensation

We follow the Financial Accounting Standard Board’s Accounting Standards Codification Topic 718 (“FASB ASC Topic 718”) for our stock-based compensation awards. FASB ASC Topic 718 requires us to measure the compensation expense for all share-based payment awards made to our employees and non-employee members of our board of directors, including options to purchase shares of our common stock and other stock awards, based on the grant date fair value of these awards. This cost is recognized as an expense following the straight-line attribution method over the requisite service period. This calculation is performed for accounting purposes and reported in the executive compensation tables required by the federal securities laws, even though the recipient of the awards may never realize any value from such awards.

Compensation Risk Assessment

In consultation with management and Compensia, our compensation and talent management committee’s independent compensation consultant, in March 2021, our compensation and talent management committee assessed our compensation plans, policies and practices for named executive officers and other employees and concluded that they do not create risks that are reasonably likely to have a material adverse effect on us. This risk assessment included, among other things, a review of our cash and equity incentive-based compensation plans to ensure that they are aligned with our performance goals and overall target total direct compensation to ensure an appropriate balance between fixed and variable pay components. Our compensation and talent management committee conducts this assessment annually.

Potential Payments Upon Termination or Change in Control

Executive Severance Plans

We maintain three separate executive severance plans (i.e., the Chief Executive Officer Severance Plan and Key Executive Severance Plan, collectively the “Executive Severance Plans,” and the VP Severance Plan). We do not provide for any severance or change in control payments or benefits in our named executive officers’ employment offer letters (except for limited vesting acceleration provisions in our Chief Revenue Officer’s promotion letter). Each of our named executive officers, including our Chief

57

Executive Officer and Chief Operating Officer and Principal Financial Officer, is a participant in the applicable Executive Severance Plan, as further described below. The Executive Severance Plans provide for certain payments and benefits in the event of a termination of employment, including an involuntary termination of employment in connection with a change in control of the Company.

Our Executive Severance Plans provide that upon a termination of employment by us for any reason other than for “cause” (as defined in the applicable Executive Severance Plan), death or disability outside of the change in control period (i.e., the period beginning three months prior to and ending 12 months after, a “change in control,” as defined in the applicable Executive Severance Plan), an eligible participant will be entitled to receive, subject to the execution and delivery of an effective release of claims in our favor, (i) a lump sum cash payment equal to nine months of base salary for our Chief Executive Officer, and six months of base salary for our other named executive officers, and (ii) a monthly cash payment for up to nine months for our Chief Executive Officer and up to six months for our other named executive officers equal to the monthly contribution we would have made to provide health insurance to the named executive officer if he or she had remained employed by us. Pursuant to the CEO Severance Plan, our Chief Executive Officer is also entitled to such benefits upon a resignation of employment for “good reason” (as defined in the CEO Severance Plan) outside of the change in control period. In addition, upon a (i) termination of employment by us other than due to cause, death or disability or (ii) a resignation of employment for “good reason”, in each case, outside of the change in control period, our Chief Executive Officer will be entitled to 12 months of acceleration of vesting for outstanding and unvested time-based equity awards.

The Executive Severance Plans also provide that upon a (i) termination of employment by us other than due to cause, death or disability or (ii) a resignation of employment for “good reason” (as defined in the applicable Executive Severance Plan), in each case, within the change in control period, an eligible participant will be entitled to receive, in lieu of the payments and benefits above and subject to the execution and delivery of an effective release of claims in our favor, (1) a lump sum cash payment equal to 18 months of base salary for our Chief Executive Officer and 12 months of base salary for our other named executive officers, (2) a monthly cash payment for up to 18 months for our Chief Executive Officer and up to 12 months for our other named executive officers equal to the monthly contribution we would have made to provide health insurance to the named executive officer if he or she had remained employed by us, and (3) full accelerated vesting of all outstanding and unvested equity awards held by our named executive officers; provided, that the performance conditions applicable to any stock-based awards subject to performance conditions will be deemed satisfied at the target level specified in the terms of the applicable award agreement.

The payments and benefits provided under the Executive Severance Plans in connection with a change in control may not be eligible for a federal income tax deduction by us pursuant to Section 280G of the Code. These payments and benefits may also subject an eligible participant, including the named executive officers, to an excise tax under Section 4999 of the Code. If the payments or benefits payable to an eligible participant in connection with a change in control would be subject to the excise tax imposed under Section 4999 of the Code, then those payments or benefits will be reduced if such reduction would result in a higher net after-tax benefit to him or her.

Other Change in Control and Severance Arrangements

The following table presents information concerning estimated payments and benefits that would be provided in the circumstances described above for each of the named executive officers who were serving as named executive officers as of the end of the fiscal year ending December 31, 2021. Messrs. Hu and Chew resigned as of October 27, 2021 and May 17, 2021, respectively, and received no compensation in connection with their terminations.

The payments and benefits set forth below are estimated assuming that the termination or change in control event occurred on the last business day of our fiscal year ending December 31, 2021 using the

58

closing market price of our stock on that date. Actual payments and benefits could be different if such events were to occur on any other date or at any other price or if any other assumptions are used to estimate potential payments and benefits.
