General Information
https://cdn.kscope.io/fcbfc24a3e09261b277a8a847f670c2f-Tandem Logo Mark Primary Blue RGB.jpg
GENERAL INFORMATION
These proxy materials are being furnished in connection with the solicitation of proxies by the Board of Directors of Tandem Diabetes Care, Inc. for use during the 2023 annual meeting of stockholders, or the Annual Meeting, to be held on Wednesday, May 24, 2023, at 3:00 p.m. Pacific time, and at any adjournment or postponement thereof. Tandem Diabetes Care, Inc. is sometimes referred to herein as “we,” “us,” “our” or the “Company.”
Notice of Internet Availability of Proxy Materials
This Proxy Statement, together with the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2022, or the Annual Report, filed with the U.S. Securities and Exchange Commission, or SEC, on February 22, 2023, is being made available to stockholders at www.proxyvote.com. The Annual Report is not a part of the proxy solicitation material. This Proxy Statement is being made available to stockholders on or about April 12, 2023. However, if you would prefer to receive printed proxy materials, please follow the instructions included in the Notice prior to May 10, 2023.
Under SEC’s “notice and access” rules, we are providing access to the proxy materials for the Annual Meeting via the internet. Accordingly, on or about April 12, 2023, we mailed a Notice of Internet Availability of Proxy Materials, or Notice, to each of our stockholders. The Notice contains instructions on how to access our proxy materials how to vote your shares through the internet, by telephone, or by mail. Please review the proxy materials prior to voting.
Stockholders Entitled to Vote
Stockholders at the close of business on March 28, 2023 (the “Record Date”) are entitled to notice of, and to attend and vote at, the Annual Meeting and at any adjournment or postponement thereof. As of the Record Date, 64,606,732 shares of our Common Stock, were outstanding. Each stockholder is entitled to one vote for each share of Common Stock owned at the Record Date.
How to Vote
If you are a stockholder of record, you may vote by proxy through the internet, by mail, or by telephone as described below:
By Internet - go to www.proxyvote.com and follow the instructions provided on the website. You will need the QR code provided on your proxy card, or your unique 16-digit control number on the Notice or, if you requested to receive printed proxy materials, the control number from the proxy card that was mailed to you.
By telephone, call toll-free 1-800-690-6903 from any touch-tone telephone and follow the instructions. You will need the 16-digit control number from the Notice or, if you requested to receive printed proxy materials, the control number on the proxy card that was mailed to you.
By Mail - complete, date, sign your proxy card and mail it in the postage-paid envelope provided. You must sign your name exactly as it appears on the proxy card. If you are signing in a representative capacity (for example, as
an officer of a corporation, guardian, executor, or trustee), you must indicate your name and title or capacity.
If you vote via the internet or by telephone, they are both available 24 hours a day and will be accessible until 11:59 p.m. Eastern Time on Tuesday, May 23, 2023 for shares held directly and until 11:59 p.m. Eastern Time on Saturday, May 20, 2023 for shares held in a Plan.
You may also vote during the virtual Annual Meeting via the internet at www.virtualshareholdermeeting.com/TNDM2023. At this site you will be able to vote electronically.
You are considered to be a stockholder of record if your shares were registered directly in your name on the Record Date. If your shares are held in a brokerage account or by a bank, broker or other nominee, and not in your name, you are considered to be the beneficial owner of shares held in street name.
The nominee holding your shares is considered the holder of record for purposes of voting at the virtual Annual Meeting. As a beneficial owner, you have the right to direct your nominee on how to vote the shares in your account. The nominee will provide you with instructions that you must follow to have your shares voted. Please contact your nominee directly if you have any questions about voting your shares.
As a beneficial owner of shares held in street name, you are invited to attend the Annual Meeting virtually. However, since you are not the holder of record, you may not vote your shares at the Annual Meeting unless you request and obtain a valid “legal proxy” or a 16-digit control number from your nominee. Please contact your nominee for additional information about attending the Annual Meeting virtually.
Change of Vote or Revocation of Proxy
Stockholders of Record: If you are a stockholder of record you may revoke your proxy or change your vote at any time before the polls are closed at the Annual Meeting by:
Timely delivery of a valid, later-dated proxy or later-dated vote by internet or telephone; or
Written notice to the Corporate Secretary of Tandem Diabetes Care, Inc., 12400 High Bluff Drive, San Diego CA 92130; or
Voting during the virtual Annual Meeting.
Beneficial Owners: If you are a beneficial owner of shares held in street name and you have instructed your bank, broker or other nominee to vote your shares, you may change your vote by following the instructions provided to you by your nominee.
Your latest-dated internet or telephone proxy, or proxy card, will be the one that is counted at the Annual Meeting. If you revoke your proxy via the internet or by telephone, please make sure to do so by the deadline as described above. If you send a written notice of revocation, please make sure to do so with enough time for it to arrive by mail prior to the Annual Meeting.

General Information
https://cdn.kscope.io/fcbfc24a3e09261b277a8a847f670c2f-Tandem Logo Mark Primary Blue RGB.jpg
Attending the Annual Meeting
The Annual Meeting will be held virtually via live webcast at www.virtualshareholdermeeting.com/TNDM2023. You will be able to attend the Annual Meeting online, submit your questions, and vote your shares during the meeting. In order to attend and participate in the Annual Meeting, stockholders will need either the QR code provided on your proxy card, or your unique 16-digit control number located on your Notice, on your proxy card (if you received a printed copy of the proxy materials) or within the instructions that accompanied your proxy materials. The webcast will begin promptly at 3:00 p.m. Pacific time on Wednesday, May 24, 2023.
We will answer as many stockholder questions during the Annual Meeting as time permits and in accordance with our rules for the meeting. However, we reserve the right to exclude questions that are not pertinent to the Annual Meeting matters or that are otherwise inappropriate. If we receive substantially similar questions, we will group such questions together and provide a single response to avoid repetition.
Technical Assistance for the Annual Meeting
Online access will begin at approximately 2:45 p.m. Pacific Time on the day of the meeting to provide you ample time to log in, test your device, and review the rules and procedures for the meeting. We encourage you to access the webcast prior to the designated start time. If you experience any technical difficulties accessing the meeting website, a toll-free technical support number will be posted on the meeting website for assistance.
Quorum, Abstentions and Broker Non-Votes
A quorum of stockholders is required to hold the Annual Meeting. A quorum exists when at least a majority of the outstanding shares of our Common Stock entitled to vote as of the close of business on the Record Date, or 32,303,367 shares, are present or represented by proxy at the Annual Meeting (even if not voting). Virtual attendance at the Annual Meeting constitutes presence for purposes of a quorum at the Annual Meeting. If a quorum is not present, the Annual Meeting may be adjourned by the chair of the meeting or by the vote of a majority of the shares present in person or represented by proxy at the Annual Meeting, in accordance with our Amended and Restated Bylaws (“Bylaws”), and applicable law, to permit the further solicitation of proxies.
Votes withheld from any director, nominee, abstentions and broker “non-votes” are counted as present or represented by proxy for purposes of determining the presence or absence of a quorum for the Annual Meeting. A broker “non-vote” occurs when a bank, broker or other nominee holding shares for a beneficial owner has not received instructions from the beneficial owner regarding the voting of the shares and does not have discretionary authority to vote the shares for certain non-routine matters.
If you are a beneficial owner of shares held in street name and do not provide the nominee that holds your shares with specific voting instructions, the nominee may generally vote in its discretion on “routine” matters. However, if the nominee that holds your shares does not receive instructions from you on how to vote your shares on a “non-routine” matter, it will be
unable to vote your shares on that matter. Whether a particular matter is considered “routine” or “non-routine” is determined pursuant to applicable stock exchange rules.
Cost of Soliciting Proxies
The cost of soliciting these proxies is being paid by the Company. In addition to solicitation by mail, proxies may be solicited by directors, officers and other employees of the Company, personally, by telephone or by other means of communication. While we have not retained a proxy solicitor to assist in the solicitation of proxies, we may do so in the future, and do not believe the cost of any such proxy solicitor will be material. The Company will, upon request, reimburse brokers and other nominees for their reasonable out-of-pocket expenses in forwarding these proxy materials to beneficial owners of shares held in street name by such persons.
Announcement of Voting Results
In accordance with SEC rules, final voting results will be published in a Current Report on Form 8-K within four business days following the Annual Meeting, unless final results are not known at that time, in which case preliminary voting results will be published within four business days of the Annual Meeting and final voting results will be published once they are known by us.
Contact Information for Questions
If you have additional questions about this Proxy Statement or the Annual Meeting, please contact the Corporate Secretary, Tandem Diabetes Care, Inc., 12400 High Bluff Drive, San Diego CA 92130 or by telephone at (858) 366-6900.
Caution Concerning Forward-Looking Statements
This Proxy Statement contains forward-looking statements within the meaning of the federal securities laws. Forward-looking statements may relate to our future financial performance, business operations, and executive compensation decisions, or other future events. You can identify forward-looking statements by the use of words such as “may,” “will,” “could,” “anticipate,” “expect,” “intend,” “believe,” “continue,” or the negative of such terms, or other comparable terminology. Forward-looking statements include the assumptions underlying or relating to such statements. We have based these forward-looking statements largely on our current expectations and projections about future events and financial trends that we believe may affect our business, results of operations and financial condition.
The outcomes of the events described in these forward-looking statements are subject to risks, uncertainties and other factors described in the section entitled “Risk Factors” in our Annual Report, as well as other filings we make with the SEC from time to time. We cannot assure you that the events and circumstances reflected in the forward-looking statements will be achieved or occur, and actual results could materially differ from those expressed or implied in the forward-looking statements.

Proposal 1 >> Election of Directors
https://cdn.kscope.io/fcbfc24a3e09261b277a8a847f670c2f-Tandem Logo Mark Primary Blue RGB.jpg
MANAGEMENT PROPOSALS
PROPOSAL 1
Election of Directors
To elect four Class I directors and three Class III directors for a one-year term expiring at the 2024 annual meeting of stockholders.
Board Structure and Membership
We currently have ten members on our board of directors and no vacancies. Pursuant to our Amended and Restated Certificate of Incorporation (the “Certificate of Incorporation”) and Bylaws, our board of directors is currently divided into three classes, as follows:
Class I, which currently consists of Mr. Kim D. Blickenstaff, Mr. Joao Malagueira, Dr. Kathleen McGroddy-Goetz, and Mr. Christopher J. Twomey, whose terms will expire at the Annual Meeting;
Class II, which currently consists of Mr. Dick P. Allen, Ms. Rebecca B. Robertson, and Mr. Rajwant S. Sodhi, whose terms will expire at our 2024 annual meeting of stockholders; and
Class III, which currently consists of Mr. Myoungil Cha, Ms. Peyton R. Howell, and Mr. John F. Sheridan, whose terms will expire at the Annual Meeting.
The board of directors has nominated Mr. Blickenstaff, Mr. Cha, Ms. Howell, Mr. Malagueira, Dr. McGroddy-Goetz, Mr. Sheridan, and Mr. Twomey, comprising all of the current Class I and Class III directors, for re-election to the board. Following stockholder approval at our 2022 annual meeting of stockholders, we filed an amendment to our Certificate of Incorporation with the Delaware Secretary of State and our Board amended our Bylaws to remove the requirement that our board of directors shall be constituted as a classified board. As a result each director who stands for election or re-election at and after the 2022 annual meeting of stockholders will be elected for a one-year term, expiring at the next year’s annual stockholder meeting. Our board structure will be completely declassified by the 2024 annual meeting of stockholders. The declassification amendment did not change the current number of directors or our Board’s authority to change the number of directors and to fill any vacancies or newly created directorships.
Directors may only be removed for cause by the affirmative vote of a majority of the outstanding shares entitled to vote upon an election of directors, voting together as a single class. Any vacant directorships may be filled by the directors then in office.
Majority Voting Standard
Pursuant to the majority voting standard, in uncontested elections, directors will be elected by the affirmative vote of a majority of the votes cast by the shares of Common Stock present or represented by proxy and entitled to vote on the proposal at the Annual Meeting. In contested elections, which are elections where the number of director nominees exceeds the number of directors to be elected at a meeting of the stockholders, directors will be elected by a plurality of the votes cast at the meeting.

Pursuant to our Bylaws, if an incumbent director nominee in an uncontested election fails to receive the affirmative vote of a majority of the votes cast in his or her election, such director must promptly tender his or her resignation to our board of directors, and our board of directors must accept or reject the tendered resignation no later than 90 days following certification of the election results. Our board of directors will also publicly disclose its decision regarding the tendered resignation and the rationale behind its decision. Any director who tenders his or her resignation pursuant to this provision of our Bylaws may not participate in the decision of the board of directors with respect to his or her resignation. Such director will continue to serve as a director after submitting his or her resignation unless and until our board of directors accepts such resignation, or until his or her earlier death, resignation (for reasons other than such director’s failure to receive the required vote) or removal. If such director’s resignation is accepted by our board of directors after the director failed to receive the required vote, or if a nominee for director is not elected and the nominee is not an incumbent director, then our board of directors, in its sole discretion, may fill any resulting vacancy or decrease the size of our board of directors in accordance with our Bylaws.
Required Vote
The election of our director nominees at the Annual Meeting requires the affirmative vote of a majority of the votes cast by the shares of our Common Stock present in person or represented by proxy and entitled to vote on the proposal at the Annual Meeting. A “majority of the votes cast” means the number of shares voted “For” a director’s election exceeds 50% of the number of votes cast with respect to that director’s election.
This proposal is considered a non-routine matter under applicable stock exchange rules. A bank, broker or other nominee may not vote without instructions on this matter, so there may be broker non-votes in connection with this proposal. Abstentions and broker non-votes are not counted as votes “For” or “Against” a director nominee and will have no effect on the election of directors. If no contrary indication is made, returned proxies will be voted “For” each of the director nominees, or in the event that any nominee is unable to serve as a director at the time of the election, returned proxies will be voted “For” any nominee who is designated by our board of directors to fill the vacancy.
OUR BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS A VOTE “FOR” EACH OF THE CLASS I AND CLASS III DIRECTOR NOMINEES

Proposal 2 >> Approval of the 2023 Long-Term Incentive Plan
https://cdn.kscope.io/fcbfc24a3e09261b277a8a847f670c2f-Tandem Logo Mark Primary Blue RGB.jpg
PROPOSAL 2
2023 Long-Term Incentive Plan
To approve the Company’s 2023 Long-Term Incentive Plan, which will replace the 2013 Stock Incentive Plan scheduled to expire on November 15, 2023.
Summary
Our board of directors believes that granting long-term incentives in the form of equity-based awards is crucial for promoting our long-term financial growth and stability, thereby enhancing stockholder value. We are asking our stockholders to approve the Tandem Diabetes Care, Inc. 2023 Long-Term Incentive Plan (“2023 Plan”). Once approved, the 2023 Plan will replace the Company’s 2013 Stock Incentive Plan, which has a scheduled expiration date of November 15, 2023 (“Predecessor Plan”). The 2023 Plan provides for the grant of Options, Restricted Stock, Restricted Stock Units or Stock Appreciation Rights (collectively, the “Awards”) to our employees, officers, directors, consultants and other service providers upon whose judgment, initiative and efforts the successful conduct and development of the Company’s business largely depends.
The 2023 Plan was approved by the Board on April 7, 2023, and will become effective and adopted on the date that it is approved by stockholders (the “Effective Date”). If stockholder approval of this proposal is obtained at the Annual Meeting, we will not grant any additional awards under the Predecessor Plan. We commit to reduce the 2023 Plan share reserve by the number of shares that we grant under the Prior Plan, minus those recycled, between February 28, 2023 and May 24, 2023 (the Annual Meeting date), unless the proposal to adopt the 2023 Plan (this Proposal No. 2) is not approved by the stockholders at the Annual meeting. Awards previously granted under the Predecessor Plan would be unaffected by the adoption of the 2023 Plan, and they would remain outstanding under the terms pursuant to which they were previously granted. If stockholder approval of this proposal is not obtained at the Annual Meeting, awards may still be granted under the Predecessor Plan until its scheduled expiration date of November 15, 2023, following which date Tandem will no longer have an equity-based compensation plan and will no longer be able to issue customary annual long-term incentive awards and other equity awards. We are therefore requesting that the stockholders approve the 2023 Plan at the Annual Meeting. Under the 2023 Plan, we will be able to grant up to 2,634,000 shares of our Common Stock, in the form of new Awards.
The following table provides certain additional information regarding Tandem Diabetes Care, Inc.’s equity compensation plans, excluding the 2023 Plan:
Use of Shares That May Be Delivered Under All Equity Compensation PlansAs of February 28, 2023
Outstanding Appreciation Awards Under All Plans

Weighted-Average Remaining Term (in years)
5.96
Full Value Awards Outstanding Under All Equity Incentive Plans1,856,060 
Number of Shares Available for Grant Under All Equity Incentive Plans80,591 
We have relied on the advice of WTW (formerly known as Willis Towers Watson), our Compensation Committee’s independent compensation consultant, as well as consulting services and data modeling tools made available by certain proxy advisory services, to assist us in developing the size of the share reserve for the 2023 Plan. Based on this advice, we believe that our share reserve request is appropriate and within industry standards.

Plan Administration
Authority to control and manage the operation and administration of the 2023 Plan shall be vested in the Board, which may delegate such responsibilities in whole or in part to the Committee. Each of the members shall meet the independence requirements under the then applicable rules, regulations or listing requirements adopted by The Nasdaq Stock Market LLC or the principal exchange on which the Common Stock is then listed or admitted to trading. Members of the Committee may be appointed from time to time by, and shall serve at the pleasure of, the Board. The Board may limit the composition of the Committee to those persons necessary to comply with the requirements of Section 16 of the Exchange Act. As used herein, the term “Administrator” means the Board or, with respect to any matter as to which responsibility has been delegated to the Committee, the term Administrator shall mean the Committee.
Award Limitations
Any Award granted under the Plan shall be granted subject to a minimum vesting period of at least twelve (12) months, such that no such Awards shall vest prior to the first anniversary of the applicable grant date. Notwithstanding the foregoing, (i) up to 5% of the aggregate number of Shares authorized for issuance under this Plan (as described in Section 4.1 of the 2023 Plan) may be issued pursuant to Awards subject to any, or no, vesting conditions, as the Administrator determines appropriate, and (ii) the Administrator may accelerate the vesting of awards before the first anniversary of the applicable grant date.
Subject to adjustment as to the number and kind of shares under Section 4.2 of the 2023 Plan, for grants to Participants that are non-employee directors of the Company, the aggregate grant date fair value of Awards granted during any one fiscal year of the Company, together with the value of any cash compensation paid to the non-employee director during such fiscal year, may not exceed $750,000 (on a per-director basis); provided however that the limitation that will apply in the fiscal year in which the non-employee director is initially appointed or elected to the Board shall instead be $1,000,000. For purposes of this limitation, the grant date fair value of an Award shall be determined in accordance with the assumptions that the Company uses to estimate the value of share-based payments for financial reporting purposes. For the sake of clarity, neither Awards granted, nor compensation paid, to an individual for his or her service as an employee or consultant but not as a non-employee director, shall count towards this limitation.
Shares Subject to the Plan
The maximum number of shares of Common Stock reserved and available for issuance under this Plan shall be 2,634,000 shares, subject to adjustment as to the number and kind of shares pursuant to Section 4.2 of the 2023 Plan.

In addition, to the extent shares of Common Stock covered by a Full Value Award are retained or are otherwise not issued by the Company in order to satisfy withholding obligations for Tax-Related Items in connection with the Full Value Award, such shares of Common Stock shall again be available for grant or issuance under the Plan. The following shares of Common Stock may not again be made available for issuance as Awards under the Plan: (x) the gross number of shares of Common Stock subject to outstanding Stock Appreciation Rights settled in exchange for shares of Common Stock, (y) shares of Common Stock used to pay the Exercise Price related to outstanding Options, or (z) shares of Common Stock used to pay withholding taxes related to outstanding Options, Stock Appreciation Rights or Restricted Stock Units.

Amendment and Termination
The Board may from time to time alter, amend, suspend, or terminate this Plan in such respects as the Board may deem advisable. No such alteration, amendment, suspension, or termination shall be made which shall substantially affect or impair the rights of any Participant under an outstanding Award Agreement without such Participant’s consent. The Board may alter or amend the Plan to comply with requirements under the Code relating to Incentive Options or other types of options which give Optionees more favorable tax treatment than that applicable to Options granted under this Plan as of the Effective Date. Upon any such alteration or amendment, any outstanding Option granted hereunder may, if the Administrator so determines and if permitted by Applicable Law, be subject to the more favorable tax treatment afforded to an Optionee pursuant to such terms and conditions. The Board may also adopt amendments of the Plan relating to certain nonqualified deferred compensation under Section 409A of the Code and/or ensuring the Plan or any Awards granted under the Plan are exempt from, or compliant with, the requirements for nonqualified deferred compensation under Section 409A of the Code, subject to the limitations, if any, of Applicable Law. Unless this Plan shall theretofore have been terminated, the Plan shall terminate on the tenth (10th) anniversary of the Effective Date and no Awards may be granted under the Plan thereafter, but Award Agreements then outstanding shall continue in effect in accordance with their respective terms.
Foreign Participants
The Board may from time to time adopt such procedures, terms and conditions and sub-plans as are necessary or appropriate to facilitate participation in the Plan by Service Providers who are foreign nationals or employed or providing services outside the United States (provided that Board approval will not be necessary for immaterial modifications to the Plan or any Award Agreements that are required or advisable for compliance with the laws of the relevant foreign jurisdiction).
Tax Treatment
The Company or any Affiliated Company, as applicable, shall have the authority and the right to deduct or withhold, or to require a Participant to remit to the Company or one or more of its Affiliated Companies, the amount of any Tax-Related Items concerning a Participant arising as a result of the Participant’s participation in the Plan or to take such other action as may be necessary or appropriate in the opinion of the Company or an Affiliated Company, as applicable, to satisfy such Tax-Related Items. The Company may defer making payment of an Award if any such Tax-Related Items may be pending unless and until indemnified to its satisfaction, and neither the Company nor any Affiliated Company shall have any liability to any Participant for exercising the foregoing right. Although the Company may endeavor to (a) qualify an Award under the Plan for favorable or specific tax treatment under the laws of the United States or jurisdictions outside of the United States or (b) avoid adverse tax treatment, the Company makes no representation to that effect and expressly disavows any covenant to maintain favorable or avoid unfavorable tax treatment, anything to the contrary in the 2023 Plan, including Section 13.2 thereof, notwithstanding. The Company shall be unconstrained in its corporate activities without regard to the potential negative tax impact on holders of Awards under the Plan. Nothing in this Plan or in an Award Agreement shall provide a basis for any person to take any action against the Company or any Affiliated Company based on matters covered by Section 409A of the Code, including the tax treatment of any Awards, and neither the Company nor any Affiliated Company will have any liability under any circumstances to the Participant or any other party if the Award that is intended to be exempt from, or compliant with, Section 409A of the Code, is not so exempt or compliant or for any action taken by the Administrator with respect thereto.

Proposal 3 >> Say-on-Pay
https://cdn.kscope.io/fcbfc24a3e09261b277a8a847f670c2f-Tandem Logo Mark Primary Blue RGB.jpg
Proposal 3:
Say-on-Pay
To approve, on a non-binding, advisory basis, the compensation of our named executive officers.
Background
In accordance with applicable SEC rules, we are providing our stockholders with the opportunity to cast a non-binding, advisory vote on the compensation of our Named Executive Officers (“NEOs”) as described in this Proxy Statement, or a “say-on-pay” proposal. We believe it reflects a sound corporate governance practice to seek the views of our stockholders on our executive compensation program.
Summary
The primary objective of our executive compensation program is to compensate our executive officers in a manner that will attract, retain and motivate talented executives with the skills needed to manage a demanding and high-growth business in a rapidly evolving, competitive and highly-regulated industry, while creating long-term value for our stockholders. When designing our 2022 executive compensation program, our Compensation Committee considered a number of factors, including stockholder feedback, feedback and advice from our independent compensation consultant, peer group and market survey data, our business objectives, the 2022 budget that was approved by our board of directors, the intense competition for executive talent within the medical device and technology industries, and the importance of retaining and motivating our employees.
For 2022, we sought to advance our strong pay-for-performance philosophy and align the interests of our executives with those of our stockholders through the adoption of our 2022 performance-based short-term cash incentive program and the grant of equity-based awards, which we balanced with guaranteed elements of compensation such as base salary and standard employee benefits. Our short-term cash incentive program was designed to reward executives for achieving pre-established financial performance objectives, product development milestones, and customer-related objectives that the compensation committee believed were critical to both our short-term success and the creation of long-term stockholder value. We also sought to align the interests of our executives with those of our stockholders by tying a meaningful portion of total compensation to increases in our value through the grant of performance and restricted stock units and stock options that provided a mix of time-based and performance-based vesting.
In 2022, we delivered worldwide sales growth, high customer satisfaction and achieved product development progress, while navigating two unfavorable market dynamics in the U.S., which scaled throughout the year. These included new challenging economic conditions, including inflation, threat of recession and a highly competitive job market, as well as intensified commercial competition. As a result of these significant headwinds, notwithstanding our notable financial and commercial success during the year, we did not meet our 2022 company goals in their entirety and our NEOs did not earn their targeted compensation for the year. We believe the compensation paid to our NEOs in 2022 reflects our strong pay-for-performance philosophy, and strikes the appropriate balance between retaining and motivating our executives, and limiting compensation-related risk.
For additional information about our executive compensation program, please refer to the section of this Proxy Statement entitled “Compensation Discussion and Analysis” and the related compensation tables, notes and narrative discussion.

Proposal
In accordance with Section 14A of the Exchange Act, we are asking our stockholders to vote FOR the approval of the following resolution at the Annual Meeting:
“RESOLVED, that our stockholders approve, on a non-binding, advisory basis, the compensation of our named executive officers, as described in the Compensation Discussion and Analysis, including the related compensation tables, notes and narrative discussion, in the Proxy Statement for our 2023 Annual Meeting of Stockholders.”
Effect of Proposal
The resolution above reflects a non-binding, advisory proposal. The approval or disapproval of this proposal by stockholders will not require our board of directors or our compensation committee to take any action regarding our executive compensation practices. The final determination of the compensation of our executive officers will continue to be made by our board of directors and our compensation committee. Our board of directors, however, values the opinions of our stockholders as expressed through their votes, as well as through other communications with us. Accordingly, although the resolution is non-binding, our board of directors and our compensation committee will carefully consider the outcome of this advisory vote, as well as stockholder feedback received from other communications, when making future executive compensation decisions.
Required Vote
The approval of this non-binding proposal requires the affirmative vote of a majority of the outstanding shares of our Common Stock present in person or represented by proxy and entitled to vote on this proposal at the Annual Meeting. This proposal is considered a non-routine matter under applicable stock exchange rules. As a result, a bank, broker or other nominee may not vote without instructions on this matter, so there may be broker non-votes in connection with this proposal.

Proposal 4:
Appointment of Independent Registered Public Accounting Firm
To ratify the appointment of Ernst & Young LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2023.
Summary
Our audit committee has appointed Ernst & Young LLP as our independent registered public accounting firm for the year ending December 31, 2023. Although not required by applicable law or stock exchange listing standards, or our Certificate of Incorporation, as a matter of good corporate governance, we are asking our stockholders to ratify the appointment of Ernst & Young LLP as our independent registered public accounting firm. Ernst & Young LLP has been auditing our financial statements since 2008.
We expect representatives of Ernst & Young LLP will be present at the Annual Meeting and will be available to respond to appropriate questions from stockholders. Additionally, the representatives of Ernst & Young LLP will have an opportunity to make a statement if they so desire.
Effect of Proposal
If our stockholders do not vote to ratify the appointment of Ernst & Young LLP as our independent registered public accounting firm for the year ending December 31, 2023, our audit committee will reconsider whether to retain the firm. Even if the selection is ratified, our audit committee, in its discretion, may direct the appointment of a different independent registered public accounting firm at any time during the year if it determines that such a change would be in our and our stockholders best interests.
Required Vote
The ratification of the appointment of Ernst & Young LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2023, requires the affirmative vote of a majority of the outstanding shares of our Common Stock present in person or represented by proxy and entitled to vote on this proposal at the Annual Meeting. This proposal is considered a routine matter under applicable stock exchange rules. As a result, a bank, broker or other nominee may generally vote without instructions on this matter, so we do not expect any broker non-votes in connection with this proposal. Abstentions on this proposal will have the same effect as a vote against this proposal. If no contrary indication is made, returned proxies will be voted “For” this proposal.

Corporate Governance
Board Role in Risk Oversight
Risk is inherent in every business, and how well a business manages risk can ultimately determine its success. We face a number of risks, including risks relating to our business, operations, strategic direction and regulatory environment, as well as legal, financial, compliance, liability, information technology, human capital management, compensation, cybersecurity, environmental, social, governance, and reputational risks. Currently, we are continuing to assess and respond to the substantial operational and commercial risks relating to the growth of our business operations while also navigating impacts related to intensifying competition and global macroeconomic conditions.
Management is responsible for the day-to-day management of risks we face, while our board of directors, as a whole and through its committees, has responsibility for the oversight of risk management. 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 adequate and functioning as designed. The role of our board of directors in overseeing the management of our risks is realized primarily through committees of our board of directors, as discussed in greater detail in the descriptions of the roles and responsibilities of each of the committees below.
Management and our board of directors assesses the Company’s risk environment on at least a quarterly basis to ensure we are adequately anticipating future exposure to liability. The board (or the appropriate board committee in the case of risks that are under the purview of a particular committee) works closely with management, and outside advisors (as needed) on the identification, evaluation and management of short-, medium- and long-term risks to ensure they are prioritized on a timely basis. Risks are typically categorized based on the potential probability and severity of the risk and addressed or escalated as appropriate. Our risk assessment process aligns with our disclosure controls and procedures. When a board committee is responsible for evaluating and overseeing the management of particular risks, the chair of the relevant committee typically reports to the full board of directors during the next board meeting. For example, our nominating and corporate governance committee receives updates and its chair makes reports to the full board of directors relating to environmental, social, and governance risks, and to assessments by third-party experts concerning our cybersecurity, information security, and data privacy risks, as well as the mitigation of those risks. Specifically, with respect to data privacy and cybersecurity, our board of directors approved the formation of the privacy and security subcommittee of the nominating & corporate governance committee to assist in oversight of risk management and compliance functions related to cybersecurity and data privacy inherent in our business and operations.
Director Nomination Process
One of the objectives of our nominating and corporate governance committee is to assemble a well-rounded board of directors that consists of directors with backgrounds that are complementary to one another, reflecting a variety of experiences, skills and expertise appropriate for a company of our scale and maturity, such as:

In considering whether to recommend any candidate for inclusion in the slate of recommended nominees for our board of directors, including candidates recommended by our stockholders, the nominating and corporate governance committee applies the following selection criteria, which are consistent with those set forth in its charter:
Each director should be committed to enhancing long-term stockholder value and must possess a high level of personal and professional ethics, sound business judgment and integrity;
The board of directors should be well-rounded, consisting of directors with backgrounds that are complementary to one another, reflecting a variety and diversity of professional experiences, skills, education, expertise, socio-economic backgrounds, and personal characteristics (including, but not limited to, diversity of gender, ethnicity, race, sexual orientation and age);
Each director should be free of any conflicts of interest which would violate applicable laws, rules, regulations or listing standards, conflict with any of our corporate governance policies or procedures, or interfere with the proper performance of his or her responsibilities;
Each director should possess experience, skills and attributes which enhance his or her ability to perform duties on our behalf. In assessing these qualities, the nominating and corporate governance committee will consider the factors listed in the graphic above and other factors such as (i) sales, marketing, manufacturing, corporate governance, (ii) experience in diabetes care, the medical device industry, business model expansion or the healthcare industry generally, (iii) the oversight or performance of clinical research studies, and (iv) experience in global commercial operations of highly regulated industries, as well as other factors that would be expected to contribute to the overall effectiveness of our board of directors;
Each director should have the willingness and ability to devote the necessary time and effort to perform the duties and responsibilities of board membership; and
Each director should demonstrate his or her understanding that his or her primary responsibility is to our stockholders, and that his or her primary goal is to serve the best interests of those stockholders, and not his or her personal interests or the interests of a particular group or stockholder.

STOCKHOLDER NOMINEES
Our nominating and corporate governance committee currently has a policy of evaluating director nominees recommended by stockholders in the same manner as it evaluates other director nominees. Under our Bylaws, stockholders wishing to propose a director nominee should send the required information to Tandem Diabetes Care, Inc., 12400 High Bluff Drive, San Diego CA 92130, Attention: Corporate Secretary.

Director Independence, Agreements and Relationships
DIRECTOR INDEPENDENCE
Our board of directors has affirmatively determined that each of Mr. Allen, Mr. Cha, Ms. Howell, Mr. Malagueira, Dr. McGroddy-Goetz, Ms. Robertson, Mr. Sodhi, and Mr. Twomey meet the definition of “independent director” under applicable SEC and Nasdaq rules. Mr. Blickenstaff and Mr. Sheridan do not meet the definition of “independent director” because Mr. Blickenstaff was our employee until March 2020, and Mr. Sheridan is our current employee.
COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
Mr. Cha, Ms. Howell, and Ms. Robertson each served on our compensation committee during the fiscal year ended December 31, 2022. Each of these members was determined to be an independent director under applicable SEC and Nasdaq rules. None of the members of our compensation committee is or has ever been an officer or employee of the Company or any of its subsidiaries. None of the members of our compensation committee had any relationship with the Company requiring disclosure under Item 404 of Regulation S-K, nor is any such relationship currently contemplated. None of our executive officers currently serves, or in the past year has served, as a member of our board of directors or compensation committee (or other committee performing equivalent functions) of any entity that has one or more executive officers serving on our board of directors or compensation committee. No interlocking relationship exists between any member of our board of directors and any member of the compensation committee (or other committee performing equivalent functions) of any other company.
We have entered into an indemnification agreement with each of our directors, including each of the current members of our compensation committee.
CERTAIN RELATIONSHIPS AND RELATED-PARTY TRANSACTIONS
Except as set forth below, there are no family relationships between any director, director nominee or executive officer. In addition, there were no transactions or series of similar transactions since January 1, 2022, and there are no currently proposed transactions, to which we were or are a party that are required to be reported in accordance with applicable SEC rules in which:
the amount involved exceeds $120,000; and
any of our directors, director nominees, executive officers, any holder of more than 5% of our Common Stock, or any member of the immediate family of any of the foregoing, had or will have a direct or indirect material interest.
Mr. Sheridan, our President and Chief Executive Officer and a member of our board of directors, and Ms. Vosseller, our Executive Vice President, Chief Financial Officer and Treasurer, are involved in a personal relationship and share a primary residence. Ms. Vosseller reports directly to Mr. Sheridan. Our board of directors is informed of the relationship and, due to the direct reporting arrangement, we have taken appropriate actions to ensure compliance with Company policies and procedures. Mr. Sheridan and Ms. Vosseller have not been and will not be involved in setting compensation or benefits for one another, which will continue to be determined by our compensation committee. In addition, in consideration of the circumstances, following Mr. Sheridan’s promotion to President and Chief Executive Officer in 2019, our audit committee implemented certain additional internal controls and procedures.
Mr. Twomey, a member of our board of directors, is the brother-in-law of one of our employees who is a manufacturing engineer whom we have employed since August 2019. Mr. Twomey does not serve on our compensation committee and is not involved in decision-making regarding his brother-in-law’s compensation. For 2022, the aggregate amount of this employee’s annual compensation was approximately $192,000, which includes the employee’s base salary and cash incentive bonus paid in 2022 as well as the value of stock-based compensation granted in 2022. The compensation structure and aggregate compensation amount paid to this employee is commensurate with our other employees with similar titles, skills and levels of experience.

PROCEDURES FOR APPROVAL OF RELATED-PARTY TRANSACTIONS
Our board of directors has adopted a Related-Party Transaction Policy to assist us in identifying, reviewing and approving or rejecting related party transactions. Under the policy, our Compliance Officer (as defined in the policy) is charged with the primary responsibility for determining whether, based on the facts and circumstances, a related person has a direct or indirect material interest in a current or proposed transaction. To assist the Compliance Officer in making this determination, the policy sets forth certain categories of transactions that are deemed not to involve a direct or indirect material interest of the related person. If, after applying these categorical standards and weighing all of the facts and circumstances, the Compliance Officer determines that the related person would have a direct or indirect material interest in the transaction, the Compliance Officer must present the transaction to the audit committee for review or, if impracticable under the circumstances, to the Chair of the audit committee. The audit committee must then either approve or reject the transaction in accordance with the terms of the policy.
LEGAL PROCEEDINGS WITH DIRECTORS
There are no legal proceedings related to any of the directors or director nominees which require disclosure pursuant to applicable SEC rules.
Board Committees
Our board of directors has three standing committees: the audit committee, the compensation committee, and the nominating and corporate governance (N&CG) committee. The privacy and security subcommittee, formed in 2021, is a standing subcommittee of the N&CG committee, focused on cybersecurity and data privacy oversight. In addition, from time to time, special committees and subcommittees may be established under the direction of our board of directors when necessary to address specific issues. For instance, as needed we have established a pricing committee to determine the offering price and other terms of various financings we have pursued.
Each of the three standing committees and one subcommittee has a written charter that has been approved by our board of directors. A copy of each charter is available at https://investor.tandemdiabetes.com/corporate-governance/esg. However, the information contained on our website is not incorporated by reference in, or considered part of, this Proxy Statement and references in this Proxy Statement to our website are to inactive textual references only.

Board Leadership Structure
Our board of directors believes it is important to maintain flexibility in our board leadership structure to best serve the interests of our Company and stockholders at any particular time. In determining the appropriate structure, our board of directors considers multiple factors, including our business and strategic needs at the time and the composition of our board. The roles of Chair of our board of directors and Chief Executive Officer are currently separate and distinct. Our board believes separating these positions allows our Chief Executive Officer to focus on the day-to-day management of our business, while allowing our Chair to focus her primary attention on matters involving strategy, corporate governance and board oversight.
Ms. Robertson has served as the Chair of our board of directors since March 2023, and as a member of our board of directors since January 2019. In her role as Chair and as an independent director under applicable SEC and Nasdaq rules, Ms. Robertson leverages her extensive experience in management positions in the medical technology industry, as well as her background working with financial statements and implementing board processes and functions to advise the Company on identified and anticipated risks, and provides oversight of management and our board of directors, drives strategy and agenda setting at the board level, and leads executive sessions of our board of directors when only non-employees are present.
Mr. Blickenstaff, who served as Chair of our board of directors until March 2023, currently serves as a member of our board of directors.
Our board of directors also firmly supports having an “independent director” serve in a board leadership position at all times, and created a Lead Independent Director role in March 2019 primarily because Mr. Blickenstaff, the former Chair of our board of directors, and Mr. Sheridan, our President and Chief Executive Officer, did not qualify as independent directors due to their historical or current employment relationships with us. Mr. Allen served as our Lead Independent Director concurrent with Mr. Blickenstaff’s tenure as Chair of our board of directors, and his designation as Lead Independent Director was removed in March 2023 effective upon Ms. Robertson’s appointment as Chair of our board. Ms. Robertson is an independent director and therefore the Board has decided to no longer designate a separate Lead Independent Director.
While our board structure fulfills the needs of the Company at this time, our board of directors regularly assesses the most appropriate board leadership structure on a regular basis and may make changes to the structure based upon the evolving needs of our business, governance best practices, and other factors deemed relevant by our board of directors.
EXECUTIVE SESSIONS
In accordance with applicable Nasdaq rules, our independent directors meet in regularly scheduled executive sessions at which only independent directors are present.
Stockholder Engagement
We have consistently demonstrated our commitment to open and interactive dialogue with our stockholders. Our relationship with our stockholders, as the owners of our Company, is an important part of our success, and we seek to engage meaningfully with our stockholders to ensure their views are shared with our board of directors and management team, and actively considered in discussions of our strategy, operational performance, financial results, corporate governance, compensation programs, and related matters.
While our board of directors has a fiduciary duty to our stockholders and represents their interests, our management team is primarily responsible for investor relations. Our management team believes that active stockholder engagement drives increased corporate accountability, improves decision making, and ultimately creates long-term value for our stockholders.

In recent years, we have taken measures to evolve our executive compensation and governance practices as the Company matures. In alignment with these efforts, we have engaged in proactive stockholder outreach to solicit feedback on our practices, and to incorporate the feedback into our decision-making processes.

2022 BUSINESS HIGHLIGHTS
Since launching our t:slim insulin pump in 2012, we have transformed our Company from a domestic venture-backed insulin pump start-up to a self-sustaining, global diabetes technology company. As a result, we have meaningfully contributed to the expansion of the United States insulin pump market, which has grown by more than 55% to approximately 800,000 people, of which Tandem customers represent more than 30%. Outside the United States, we have approximately 130,000 customers using a t:slim X2 pump in approximately 25 different countries after only four full years of commercial sales.
In 2022, we continued to increase our record-high customer base to new levels with more than 420,000 in-warranty customers worldwide now using the t:slim X2 for their insulin therapy needs. This achievement was demonstrated while we navigated two unfavorable market dynamics in the U.S., which scaled throughout the year. These included challenging economic conditions, including inflation and threat of recession, and intensifying competition. Outside the United States, our 20% growth in people adopting our t:slim X2 pump was masked due to variability in ordering patterns as a result of broader supply chain challenges. These pressures were partially offset by our strong growth in the overall number of our existing customers purchasing renewal pumps, but also the rate of renewals, as the proportion of people eligible to renew who actually renewed increased steadily throughout the year. This, coupled with the strong retention of our in-warranty customers, demonstrates the high level of satisfaction people experience with our technology. This is a reflection of the overwhelming positive sentiment for our Control-IQ technology by customers and healthcare providers worldwide, with high regard for the immediate and sustained benefits it offers. This, in combination with the positive experience our customers report having with our technology and services, demonstrates that we are advancing our mission to improve the lives of people with diabetes.
The information below highlights some of the important progress made in our business during 2022:
Commercial Execution
and Financial Growth
Operating Effectiveness
and Financial Management
Product Pipeline Advancements
Increased worldwide installed base ~30% to approximately 420,000 customers.
Achieved 7% Adjusted EBITDA Margin*
Received U.S. FDA clearance and launched a feature that allows t:slim X2 customers to bolus using our t:connect Mobile App on Android and iOS devices.
Achieved 2022 sales exceeding $800 million, setting quarterly records throughout the year.
Ended the year with cash and short-term investments of $617 million.
Submitted a 510(k) pre-market notification to the U.S. FDA for the Mobi Insulin Delivery System.
Expanded worldwide insulin pump market with approximately half of new U.S. customers adopting t:slim X2 from using multiple daily injection.
Reinvested positive cash flow into R&D spending and strategic investments and acquisitions to drive long-term product pipeline.
Executed on our five-year product strategy with the acquisitions of Capillary Biomedical and AMF Medical SA in support of a portfolio approach to meet the needs of different segments of people living with diabetes.
*EBITDA, Adjusted EBITDA, and Adjusted EBITDA Margin are non-GAAP financial measures. GAAP refers to accounting principles generally accepted in the United States of America. EBITDA is defined as net income (loss) excluding income taxes, interest and other non-operating items and depreciation and amortization. Adjusted EBITDA further adjusts for the change in fair value of common stock warrants, non-cash stock-based compensation expense, acquired in-process research and development, and revenue adjustments for the Tandem Choice technology access program. Adjusted EBITDA Margin is calculated as Adjusted EBITDA divided by non-GAAP sales.

2022 COMPENSATION OVERVIEW
We entered 2022 expecting our business to achieve:
Substantial increases in product shipments and sales, both in the United States and outside the United States;
Improvement in our operating and gross margins;
Positive cash flow from operations; and
Various goals relating to our customer satisfaction and a new product submission to the U.S. Food and Drug Administration for the clearance of a new product.
When designing our 2022 executive compensation program, the Committee considered a number of factors, including the business objectives set forth above, the 2022 budget approved by our board of directors, and the intense competition for executive talent within the medical device and technology industries, both generally and within the geographic regions in which we operate. In addition, the Committee considered the continued importance of retaining and motivating our employees during uncertain global macroeconomic conditions and a particularly competitive environment for talent.
In making compensation decisions for 2022, the Committee focused on several key factors of our executive compensation program, as follows:
Stockholder feedback in response to our engagement outreach;
A peer group analysis performed by our independent compensation consultant;
Reviewing total NEO compensation compared to the 60th percentile of the peer group;
Allocating a meaningful proportion of the total cash compensation opportunity to our annual short-term cash incentive plan, under which executives are only eligible to receive cash bonuses upon the achievement of certain predetermined financial and operational performance goals; and
Allocating a meaningful proportion of the total compensation opportunity to longer-term incentive equity awards aligning with the interests of our stockholders.

Compensation Philosophy and Objectives
The primary objective of our executive compensation program is to attract and retain talented executives with the skills needed to manage and staff a demanding and high-growth business in a rapidly evolving, competitive and highly regulated industry, while motivating them to create long-term value for our stockholders. There is significant competition for talented executives, especially in the medical device and technology industries both generally and in the geographic regions in which we operate. When establishing our executive compensation program, the Committee is guided by the following four principles:
Attract, retain and motivate executives with the background and experience required for our future growth and success;
Provide a total compensation package that is competitive with other companies in the medical device and technology industry that are similar to us in size and stage of growth;
Align the interests of our executives with those of our stockholders by tying a meaningful portion of total compensation to increases in our value through the grant of equity-based awards; and
Apply a pay-for-performance philosophy by tying a meaningful portion of potential total short- and long-term compensation to the achievement of predetermined objectives that are important to our growth and success, which can increase or decrease to reflect achievement with respect to the objectives.
ROLES AND RESPONSIBILITIES
A well-designed, implemented, and communicated executive compensation program is important to the growth and success of our business. As such, the Committee, together with input from its independent compensation consultant and management, where appropriate, works throughout the year to monitor the effectiveness of the program design. To ensure the process is robust and effective, each group typically has a specific role in the process.
Compensation Committee
The Committee is comprised solely of directors who qualify as “independent directors” under Nasdaq rules and also meet the heightened independence requirements under SEC rules. The Committee is primarily responsible for developing, reviewing and approving our executive compensation program, including the compensation arrangements that apply to our NEOs, and regularly reporting to our board of directors regarding the adoption of such programs. In particular, the Committee is responsible for overseeing our short-term cash and long-term equity incentive plans, including approving individual grants or awards thereunder (subject to the delegation of limited discretion to certain executive officers to approve individual grants or awards to employees below the executive level). The Committee is also responsible for approving performance goals and objectives that are relevant to the compensation of our executive officers and other key employees.

https://cdn.kscope.io/fcbfc24a3e09261b277a8a847f670c2f-Tandem Logo Mark Primary Blue RGB.jpg
The Committee evaluates the total compensation of our NEOs and other executives relative to available compensation information from companies in our industry that are similar to us based on a number of factors, including size and stage of growth. The Committee’s historical practice has been to benchmark our total executive compensation to just above market at the 60th percentile compared to relevant survey data, in order to compete in the market for talented executives. However, this is only the starting point for the Committee’s determination of compensation, and it retains the discretion to adjust executive compensation based on a number of factors, including changes to our peer group, changing pay practices in our industry, executive retention concerns, individual executive performance, and overall Company performance.
The Committee has not established any formal policies or guidelines for allocating between long-term and short-term compensation, or between cash and equity compensation. In determining the amount and mix of compensation elements and whether each element provides the correct incentives in light of our compensation objectives, the Committee relies on its judgment and experience, as well as significant feedback from its independent compensation consultant, rather than adopting a formulaic approach to compensation decisions.
Management
Historically, our President and Chief Executive Officer, our Executive Vice President and Chief Administrative Officer, and our Senior Vice President, Human Resources and Organizational Development, have provided input and recommendations to the Committee on the compensation of executive officers and other senior management personnel. In addition, representatives from our finance and legal functions have provided information or recommendations to the Committee regarding incentive program design. The Committee reviews this input and information and considers these recommendations. However, all decisions affecting executive officer compensation are made by the Committee, in its sole discretion.
Independent Compensation Consultants
The Committee has sole authority to engage and retain independent compensation consultants and to directly oversee their work and compensation.
In August 2020, the Committee engaged WTW (formerly known as Willis Towers Watson) as its independent compensation consultant, to provide advisory services. These services included advising the Committee on the selection of an appropriate peer group of other publicly traded healthcare companies, collecting and analyzing compensation data from those companies, and performing an independent review of our compensation practices for our executive officers, as well as our non-employee directors, as compared to the peer group. The Committee selected WTW based on its experience providing expert, strategic and research-driven executive compensation advice to help companies balance talent and governance risks while driving business performance. In addition, the Committee assessed whether work performed or advice rendered by WTW would raise any conflicts of interest and determined that there are no conflicts of interest with respect to this advisor.
KEY CONSIDERATIONS
In designing our 2022 executive compensation program, stockholder feedback and WTW analysis and advisory services were key considerations for the Committee.
Stockholder Advisory Vote on Executive Compensation
At our 2022 annual meeting of stockholders, 98.45% of our stockholders approved, on a non-binding, advisory basis, the compensation of our NEOs (i.e., our “say-on-pay” proposal).
Our board of directors has adopted a policy providing for annual “say-on-pay” votes, which was approved by our stockholders in 2019. Our board of directors believes that allowing our stockholders to vote on our executive compensation practices on an annual basis aligns with market best practices and provides our stockholders with an important opportunity to provide meaningful feedback to us.
A vote on the frequency of future “say-on-pay” votes (commonly known as a “say-on-frequency” vote) is required every six years. Accordingly, we currently expect to hold the next “say-on-frequency” vote at our 2025 annual meeting of stockholders.

Additional Compensation Plan Considerations
In addition to stockholder feedback and independent compensation consultant analysis and input, in designing our executive compensation program the Committee also takes into account various factors, including:
Overall compensation strategy, philosophy and objectives;
Criticality of individual roles and positions;
Historical and current compensation levels;
Employee tenure;
Relative compensation levels across the executive team;
Existing levels of equity ownership;
Prior equity grants, including associated vesting schedules, inherent economic value and perceived retentive value; and
Individual factors specific to each NEO, including, but not limited to, experience, performance, leadership and expertise.
In addition, the Committee reviews market factors including peer group and market survey data, as discussed below.
MARKET FACTORS
Peer Group
WTW was engaged by the Committee to develop a set of peer group companies for use as a point of comparison in benchmarking 2022 compensation for executive officers and non-employee directors. Data compiled from this peer group was used as a baseline reference by the Committee to assist it in establishing and assessing target total compensation levels, as well as target compensation levels for individual components of compensation, for our executive officers.
The inputs used to identify the peer group companies reflect the Global Industry Classification Standard and the determination of such companies included review of companies traded on major U.S. stock exchanges, companies classified in the health care equipment and health care services industries, and revenue. The revenue for our 2022 peer group companies generally fell within a range of approximately 0.5x to 2.5x our projected 2022 revenue. However, not every company in our 2022 peer group satisfied each criterion and the Committee applied its judgment and experience in making final determinations for the companies included in the peer group. For example, Dexcom exceeded our target criteria range, but the Committee determined that they should be included in our 2022 peer group because of their strong similarities to our business operations and industry.
Our worldwide sales for 2021 were approximately $703 million, or an increase of 41% compared to 2020. This substantial year-over-year growth was considered in determining our 2022 peer group. Based on the factors discussed above, our 2022 peer group is comprised of the 18 companies listed below, all of which were part of our 2021 peer group:
AbiomedCryolifeICU Medical
Nevro
AtriCure
Dexcom
InogenQuidel
BioTelemetryGlaukosInsuletSTAAR Surgical
Cardiovascular Systems
Globus Medical
iRhythm Technologies
CONMED
Haemonetics
Masimo
We consider these companies to be our peers solely for executive and director compensation comparison purposes.

Compensation Survey Data
To supplement data regarding the peer group companies where sufficient information is not available or where the Committee requests further information, the Committee also reviews from Aon Hewitt’s Radford suite of surveys. These surveys include compensation data from medical technology and life sciences companies. WTW has used data specific to our business in terms of industry, size and geographic location when providing this additional information to the Committee. In addition, for prospective new hire candidates, the Committee reviews information from these compensation surveys as a factor in the development of compensation offers.
Compensation Elements
The Committee, with assistance from our independent compensation consultant and management, has developed an executive compensation program consisting of several key components. Each element of compensation has a specific purpose and they work together to advance our overall pay-for-performance compensation philosophy and support our compensation objectives. We believe the compensation elements are generally consistent with those paid to or awarded by our peer group companies.
Based on the information provided by our independent compensation consultants, the executive compensation program for our NEOs generally consists of a:
Base salary;
Short-term cash incentive program;
Long-term equity incentive program; and
Other benefits.
BASE SALARY
The purpose of this element is to provide a fixed compensation amount to each NEO in return for performance of core job responsibilities. We pay base salaries to attract and retain executives with the necessary experience to contribute to our future growth and success. The Committee establishes base salaries after reviewing peer group compensation data and considering a number of the other factors discussed above, including each executive officer’s title and responsibility level, tenure with us, individual performance and business experience. Salaries are reviewed and potentially adjusted annually, or more frequently if the Committee deems necessary or appropriate.
The base salary for each of our NEOs was generally shown to be in alignment with benchmark data at the 60th percentile. Accordingly, a merit increase of approximately 3% was provided to each of our NEOs in 2022.

SHORT-TERM CASH INCENTIVE PROGRAM
The purpose of this element is to reward executives for achieving pre-established financial and strategic goals that the Committee believes are critical to our short-term success and the creation of long-term stockholder value. Target short-term incentive opportunities are expressed as a percent of base salaries and reviewed as part of the Committee’s annual compensation analysis, which includes an assessment of each NEO’s title and level of responsibility, and perceived ability to impact overall Company results.
2022 SHORT-TERM CASH INCENTIVE PROGRAM TARGETS
In 2022, no changes were made to the short-term incentive bonus percentage targets for the NEOs compared to 2021. The 2022 base salary, target bonus percentage and target cash bonus amount for each NEO is set forth in the table below:
Name2022 Base Salary Target Bonus Percentage Target Cash Bonus
John F. Sheridan$710,700  100% $710,700

2022 SHORT-TERM CASH INCENTIVE PROGRAM SUMMARY AND RESULTS
The 2022 short-term cash incentive program is referred to as our 2022 Cash Bonus Plan. The 2022 Cash Bonus Plan was designed to reward plan participants for their individual contributions to our achievement of pre-established financial performance objectives, a significant product development milestone, and customer-related objective for 2022. Based on stockholder feedback, our plan design has 3 components with minimum and outperformance thresholds for each component of the plan. In addition, payments for outperformance achievements are capped at 200% for each component of the plan. The metrics were selected by the Committee as representative measures of overall corporate performance for the fiscal year in February 2022 and were consistent with the 2022 budget approved by our board of directors at that time. These metrics were determined to be appropriately rigorous as an interim step toward meeting our longer-term growth and financial objectives.

The goals associated with each component of the 2022 Cash Bonus Plan were set at the beginning of the year, and the Company’s performance against these goals was reviewed with the Committee periodically throughout 2022. For the financial performance objectives, a minimum threshold of 90% of the revenue target had to be achieved for 50% bonus to be earned. For achievement of 110% or greater of the revenue target, up to 200% of the bonus may be earned. For the portion of the cash bonuses that relates to product development, a regulatory submission must be completed within a required time period. In addition, there are predefined time periods serving as a minimum threshold for achieving 50% payout and outperformance threshold for achieving up to 200% payout under this component of the plan. For the portion of the cash bonuses that relates to customer satisfaction, an annual metric must be achieved with predefined metrics serving as a minimum threshold for achieving 50% payout and outperformance threshold for achieving up to 200% payout under this component of the plan.
The following table shows each of the components of the 2022 Cash Bonus Plan, their respective weightings, our level of achievement for each component as determined by the Committee, and the calculation of the payout for each component:

**EBITDA, Adjusted EBITDA, and Adjusted EBITDA Margin are non-GAAP financial measure. GAAP refers to accounting principles generally accepted in the United States of America. EBITDA is defined as net income (loss) excluding income taxes, interest and other non-operating items and depreciation and amortization. Adjusted EBITDA further adjusts for the change in fair value of common stock warrants, non-cash stock-based compensation expense, acquired in-process research and development, and revenue adjustments for the Tandem Choice technology access program. Adjusted EBITDA Margin is calculated as Adjusted EBITDA divided by non-GAAP sales.
Based on these achievements, the Committee approved cash bonuses to our NEOs in February 2023 in the amounts set forth opposite their names in the table below:

The performance-based cash bonuses paid to our NEOs pursuant to the 2022 Cash Bonus Plan were directly aligned with our financial performance, the achievement of critical strategic and operational objectives. Overall, the Committee believes the cash bonuses reflect our strong pay-for-performance philosophy.
LONG-TERM INCENTIVE EQUITY COMPENSATION PROGRAM
We leverage long-term incentive (“LTI”) equity as a component of our executive compensation program to align the interests of our executives with those of our stockholders by tying a meaningful portion of total compensation to increases in the value of our Company through the grant of equity-based awards. The executives’ interests are aligned with those of our stockholders because, as the value of our Company increases over time, the value of the executives’ equity grants increases as well. The Committee also believes that granting equity awards that vest upon the achievement of long-term performance metrics supports our pay-for-performance philosophy, while granting equity awards that vest over time promotes the retention of our executives.
Our board of directors and stockholders have approved our 2013 Plan, which allows for the issuance of equity awards to our officers, directors and employees in the form of stock options, restricted stock awards, stock appreciation rights, and restricted stock units (“RSUs”). Since 2019, the Committee has continued to evolve the long-term incentive equity programs for our NEOs to reflect incentives aligned with the Company’s maturation and evolving governance practices in response to stockholder feedback. For example, in 2020, the Committee evolved our NEO equity compensation model from issuing predetermined, fixed share-denominated option awards to predetermined, value-denominated equity awards. In 2021, we also began including PSUs, in addition to RSUs and options, and scaled the weighting of the PSUs in 2022.
Although the Committee has not yet made awards to our CEO during the current year, in 2023 we intend to further increase the weighting of the PSU component of his LTI plan so that PSUs represent 50% of Mr. Sheridan’s LTI opportunity, and RSUs and options each represent 25% of his LTI opportunity. In addition, the Committee plans to include a total stockholder return (“TSR”) metric compared to the Russell 3000 index for a portion of his PSU targets. The Committee plans to continue executing its strategy to evolve the Company’s compensation practices, while attracting, motivating and retaining top executive talent who are dedicated to the future growth and success of our business.

The Committee considered these allocations appropriate, as performance-orientation is reflected in PSUs (which only have value if the Company achieves certain pre-determined goals) and stock options (which only have value to the extent the Company’s stock price increases from the stock price on the grant date), while grants of RSUs allow the program to support retention throughout a full business cycle. When determining the type, number and value of equity awards to be granted to each executive, the Committee generally considers several factors, including WTW’s analysis based on data from our peer group companies, the title and level of responsibility of the executive, the executive’s tenure with us, survey information regarding the level of equity ownership by executives with similar titles and levels of responsibility, and other compensation survey data. The Committee also takes into account our achievement of significant milestones during the period prior to the grant date, such as revenue growth achievement, completing or receiving regulatory clearance or approval to commercialize products.
2022 LTI Equity Compensation Program
In May 2022, in light of the various factors described above, and based on data provided by WTW, the Committee approved equity award values to each of our NEOs pursuant to our 2013 Plan as set forth in the table below:

Susan M. Morrison$360,541 5,523$371,508 5,691$360,598 8,544
Each of the PSUs has a grant date fair value of $65.28 per share and vests based on three year criteria that correlate with the number of regulatory submissions filed for new delivery devices or Automated Insulin Dosing (AID) indications, which will be measured at the end of 2024 and paid in 2025. Each of the RSUs has a grant date fair value of $65.28 per share and vests over a period of 36 months, with 33% of the shares vesting on the date that is 12 months following the grant date, and the remaining 67% of the shares vesting in equal quarterly installments over the remaining 24 months, subject to continued employment and the terms of the 2013 Plan. Each of the stock options has an exercise price of $65.28 per share and vests over a period of 36 months, with 33% of the shares vesting on the date that is 12 months following the date of grant, and the remaining 67% of the shares vesting in equal monthly installments over the remaining 24 months, subject to continued employment and the terms of the 2013 Plan.
When establishing the plan design for the PSUs issued as part of the Company’s 2022 LTI equity program, the Committee identified that executing on its product portfolio strategy through the launch of new products was a key driver of long-term stockholder value, and in support of the Company’s priority to achieve meaningful sales growth, while improving gross margin and operating margin. We consider the number of regulatory submissions targeted to be commercially sensitive, and so are not disclosing the forward-looking goal due to risk of competitive harm, but will disclose the number on a backwards looking basis following the close of performance period. The PSU component of our 2022 LTI plan is as follows:

2023 COMPENSATION DECISIONS
In 2022, notwithstanding our notable financial and commercial success, we only partially achieved our company goals and as a result there was a decline in stockholder value. In alignment with our pay-for-performance philosophy, our NEOs did not earn their targeted compensation for the year and agreed there should be no increase in their salary or bonus target in 2023.
The Committee aligns its LTI award timing with its annual meeting of stockholders. Although awards have not yet been made to our NEOs during the current year, in 2023 the Committee intends to further increase the weighting of the PSU component of our Chief Executive Officer’s LTI plan so that PSUs represent 50% of his LTI opportunity, RSUs represent 25% and options represent 25% of his LTI opportunity. In addition, the Committee plans to include a Total Stockholder Return metric for a portion of his PSU targets. The Committee plans to continue executing its strategy to evolve the Company’s compensation practices, while attracting, motivating and retaining top executive talent who are dedicated to the future growth and success of our business.
These decisions will be more fully discussed in the proxy statement for our annual meeting of stockholders to be held in 2024.
BROAD-BASED BENEFIT PROGRAMS
All full-time employees may participate in our health and welfare benefit programs, including medical, dental and vision care coverage, disability and life insurance, our employee stock purchase plan and our 401(k) plan.
We have adopted a defined contribution 401(k) plan for the benefit of our employees. Employees are eligible to participate in the plan beginning on the first day of the calendar quarter following their date of hire. Under the terms of the plan, employees may make voluntary contributions as a percent of compensation. In 2022, we began offering a 401(k) match to all participating employees, which is a feature we did not offer historically.
We also offer a standard benefits package that we believe is necessary to attract and retain key executives. Our NEOs are eligible to participate in our health and welfare benefit programs on terms consistent with those of our other employees, including employer-sponsored disability and life insurance.
Compensation Governance
COMPENSATION RISK ASSESSMENT
We assess whether our compensation programs and strategy encourage undue or inappropriate risk taking by our executive officers and other employees. We believe that, although a portion of the compensation provided to our executive officers and other employees is subject to the achievement of specified Company performance criteria, our executive compensation program does not encourage excessive or unnecessary risk-taking. We do not believe our compensation programs are reasonably likely to have a material adverse effect on us.

2006 Stock Incentive Plan
Our 2006 Plan was originally approved by our board of directors in September 2006, was subsequently approved by our stockholders in July 2007 and was most recently amended in April 2013. We had 24,352 shares of our Common Stock for reserved issuance pursuant to awards that were outstanding under our 2006 Plan as of December 31, 2022.
2013 Stock Incentive Plan
Our board of directors and our stockholders have approved our 2013 Plan. Our 2013 Plan provides us flexibility with respect to our ability to attract and retain the services of qualified employees, officers, directors, consultants and other service providers upon whose judgment, initiative and efforts the successful conduct and development of our business depends, and to provide additional incentives to such persons to devote their effort and skill to the advancement of our Company, by providing them an opportunity to participate in the ownership of our Company and thereby have an interest in its success and increased value.
We had an aggregate of 118,843 shares of our Common Stock reserved for issuance under our 2013 Plan as of December 31, 2022. As of December 31, 2022 we had outstanding awards to issue 6,251,793 shares of our Common Stock under our 2013 Plan.
2023 Long-Term Incentive Plan
Our board of directors approved our 2023 Long-Term Incentive Plan in March 2023 and we are asking our stockholders to approve the 2023 Plan at the Annual Meeting. Once approved by stockholders, the 2023 Plan will replace the Company’s 2013 Stock Incentive Plan, which has a scheduled expiration date of November 15, 2023. Our board of directors believes that granting long-term incentives in the form of equity-based awards is crucial for promoting our long-term financial growth and stability, thereby enhancing stockholder value. Under the 2023 Plan, we will be able to grant up to 2,634,000 shares of our Common Stock, in the form of new Awards.
2013 Employee Stock Purchase Plan
Our board of directors and our stockholders have approved our ESPP. The purpose of our ESPP is to retain the services of new employees and secure the services of new and existing employees while providing incentives for such individuals to exert efforts toward our growth and success. Our ESPP is intended to qualify as an “employee stock purchase plan” within the meaning of Section 423 of the Internal Revenue Code.

Our ESPP authorizes the issuance of shares of our Common Stock pursuant to purchase rights granted to our employees or to employees of any of our designated affiliates. We had an aggregate of 953,415 shares of our Common Stock reserved for issuance under our ESPP as of December 31, 2022.
PAY RATIO DISCLOSURE
In accordance with applicable SEC rules, we determined that the 2022 annualized total compensation of the median compensated employee of all our employees who were employed as of November 1, 2022, other than our Chief Executive Officer at that time, Mr. Sheridan, was $82,629. Mr. Sheridan’s 2022 annualized total compensation was $6,378,515. Among other items, total compensation includes base salary, cash incentive awards and equity-based compensation awards (valued based on the grant date fair value of awards granted during 2022), calculated as of December 31, 2022. As calculated in this manner, Mr. Sheridan’s 2022 annual total compensation was approximately 77 times that of the 2022 annualized total compensation of our median compensated employee.
To identify the median compensated employee consistent with SEC rules, we used base salary for 2022 as a measure of annual total compensation. As of November 1, 2022, we had 2,525 employees who were employed and not on leaves of absence, consisting of 2,490 U.S. employees, and 35 employees located in Canada and Europe. As permitted by applicable SEC rules, we did not include any of our 35 employees located outside the United States, consisting of approximately 1% of our total employee population, pursuant to the de minimis exemption for foreign employees. Except for these foreign employees, we did not exclude from the calculation of the median employee any other employees pursuant to any other permitted exemptions. We did not apply any cost-of-living adjustments as part of the calculation.
We believe the pay ratio is a reasonable estimate calculated in a manner consistent with applicable SEC rules based on our internal payroll and employment records and the methodology described above.
However, because the SEC rules for identifying the median compensated employee and calculating the pay ratio based on that employee’s annual total compensation allow companies to adopt a variety of methodologies, to apply certain exclusions, and to make reasonable estimates and assumptions that reflect their compensation practices, the pay ratio reported by other companies (including other companies within our peer group) may not be comparable to the pay ratio reported above, as other companies may have different employment and compensation practices and may utilize different methodologies, exclusions, estimates and assumptions in calculating their own pay ratios.
PAY VERSUS PERFORMANCE TABLE
The table below sets forth the following information for the past three fiscal years: (i) the total compensation for our principal executive officer (“PEO”) and average total compensation for our non-PEO named executive officers (“NEOs”) ; (ii) the “compensation actually paid” to our PEO and the average compensation actually paid to our non-PEO NEOs (as determined under SEC rules); (iii) our TSR; (iv) the TSR of the Russell 3000 Index ; (v) our net income (loss); and (vi) our Company-selected financial measure, sales. “Compensation actually paid” does not represent the value of cash and shares of our Common Stock received by NEOs during the year, but rather is an amount calculated under SEC rules and includes year-over-year changes in the value of unvested equity-based awards. As a result of the calculation methodology required by the SEC, amounts under the caption “Compensation Actually Paid” below differ from compensation actually received by our NEOs and the compensation decisions described in the “Compensation Discussion and Analysis” section above.

Relationship Between Pay and Performance
We believe “Compensation Actually Paid” in each of the years reported above and over the three-year cumulative period is reflective of the Committee’s emphasis on “pay-for-performance.” The chart below shows how PEO and non-PEO NEO Compensation Actually Paid fluctuated year-over-year, primarily due to the result of our varying levels of achievement against pre-established performance goals under our short-term cash incentive plan (“STIP”).

Our Company-selected measures, worldwide sales and adjusted EBITDA Margin results as well as certain other important financial performance measures set forth in the table below, were stronger in 2020 and 2021 than in 2022, which led to higher compensation actually paid in those years.
PERFORMANCE MEASURES USED TO LINK COMPANY PERFORMANCE AND COMPENSATION
ACTUALLY PAID TO THE NEOS

The following is a list of financial and financial-related performance measures, which in our assessment represent the most important measures used by the Company to link compensation actually paid to our PEO and non-PEO NEOs for 2022. Worldwide sales and the associated Adjusted EBITDA Margin* achievement are the two primary measures that are factored into 80% of the weighing in our STIP. Because bringing innovative products to people living with diabetes is intended to drive sales growth and improve gross margin, the timing of regulatory submissions was included as 10% of the weighting in our STIP, and was the performance measure for the PSUs granted as part of our long-term incentive program. In addition, key performance indicator scores for our customer satisfaction were included as the remaining 10% of the weighting in our STIP. This measure was selected as satisfaction is a key factor for customers determining to purchase a new pump from Tandem once again, which drives sales growth and provides increased predictability for our business model. It also aligns as a mission driven measure as we work to improve the lives of people with diabetes worldwide.
Most Important Performance Measures Used to Link Compensation Actually Paid to Company Performance:
Sales (Company-selected measure)
Adjusted EBITDA Margin* (Company-selected measure)
Regulatory submission timing
Customer satisfaction
*EBITDA, Adjusted EBITDA, and Adjusted EBITDA Margin are a non-GAAP financial measure. GAAP refers to accounting principles generally accepted in the United States of America. EBITDA is defined as net income (loss) excluding income taxes, interest and other non-operating items and depreciation and amortization. Adjusted EBITDA further adjusts for the change in fair value of common stock warrants, non-cash stock-based compensation expense, acquired in-process research and development, and revenue adjustments for the Tandem Choice technology access program. Adjusted EBITDA Margin is calculated as Adjusted EBITDA divided by non-GAAP sales.
Please see the section entitled “Compensation Discussion and Analysis” for additional information regarding the metrics used in the Company’s executive compensation program.
HEDGING AND PLEDGING POLICY
Our insider trading policy prohibits our employees, including our NEOs, from engaging in transactions to “hedge” ownership of our Common Stock, including short sales or trading in any derivatives involving our Common Stock (or securities convertible or exchangeable for our Common Stock). We believe this policy is consistent with good corporate governance and with our pay-for-performance compensation model. Our policies also prohibit the pledging of our Common Stock. There are no outstanding pledged shares.
CLAWBACK POLICY
In accordance with the provisions of Section 304 of the Sarbanes-Oxley Act of 2002, if we are required, as a result of misconduct, to restate our financial results due to our material noncompliance with any financial reporting requirements under the federal securities laws, our Chief Executive Officer and Chief Financial Officer may be legally required to reimburse us for any bonus or other incentive-based or equity-based compensation they received as a result of the material noncompliance.

In 2020, our board of directors adopted a clawback policy to create greater accountability for our executive officers and employees. This policy establishes the circumstances under which we will seek recoupment of cash or equity bonus or incentive compensation paid to or received by, and to recover profits realized from the sale of shares of our Common Stock by, executive officers and certain other employees in the event we are required to restate any of our publicly reported financial statements.
If our audit committee determines that fraud or intentional misconduct by an executive officer caused or substantially caused an accounting restatement, we will seek to recover from that executive officer the amount or value of any incentive compensation the executive officer received during the three years preceding the restatement that exceeds that amount or value of incentive compensation the executive officer would have received on the basis of the restated financial statements. We will also seek to recover from such executive officer any net profits the executive officer realized from sales of our Common Stock during the 12-month period preceding the publication of the restated financial statements. Similar recoupment provisions apply with respect to non-executive officer employees.
Our board of directors believes the adoption of our clawback policy is consistent with our executive compensation philosophy and objectives, and in furtherance of the board of directors’ intention to follow sound corporate governance practices.
STOCK OWNERSHIP GUIDELINES
In August 2020, our board of directors adopted stock ownership guidelines, which were then amended in February 2022. These guidelines require all executive officers and directors to own a significant ownership interest in our Common Stock, subject to a phase-in period, in order to align their interests with those of our stockholders and in furtherance of the board of directors’ intention to follow sound corporate governance practices. The holding requirements are as follows:
President and Chief Executive Officer - 3x base salary
All executive vice presidents - 1x base salary
Any other executive officers - 1x base salary
Non-employee directors - 3x annual director cash retainer (excluding committee service retainer)
The holding requirements are subject to a three-year phase-in period for executive officers and a five-year phase in period for directors. In addition to unvested stock options, unvested shares of restricted stock, and unvested performance stock units, which were previously not included for purposes of calculating the holding requirements, the amended guidelines also do not include vested, unexercised stock options. The Committee evaluates compliance with our stock ownership guidelines annually. Currently, all executive officers and directors are in compliance with the holding requirements or are within the applicable phase-in periods.
TAX AND ACCOUNTING CONSIDERATIONS
In making executive compensation decisions, the Committee considers the impact of the provisions of Section 162(m) of the Code. This section generally limits the deductibility of compensation paid by a publicly held company to “covered employees” for a taxable year to $1.0 million, except for certain “performance-based compensation” payable pursuant to written contracts that were in effect on November 2, 2017 and that are not modified in any material respect on or after that date. “Covered employees” generally include our Chief Executive Officer, Chief Financial Officer and other highly compensated executive officers. Thus, our tax deduction with regard to compensation of these officers is limited to $1.0 million per taxable year with respect to each such officer. With respect to cash and equity awards that were in effect on November 2, 2017, and that are not modified in any material respect on or after that date, the Committee is mindful of the benefit to us and our stockholders of the full deductibility of compensation, it believes that it should not be constrained by the requirements of Section 162(m) where those requirements would impair flexibility in compensating our executive officers in a manner that can best promote our corporate objectives. Therefore, the Compensation Committee has not adopted a policy that requires that all compensation be deductible. Instead, the Compensation Committee intends to compensate our executive officers in a manner consistent with the best interests of our company and our stockholders.

The Committee also considers the impact of Section 409A of the Code, and in general, our executive plans and programs are designed to comply with the requirements of that section so as to avoid possible adverse tax consequences that may result from noncompliance.
Although we review and consider the tax and accounting laws, rules, and regulations that may impact our executive compensation program, we believe it is not in the best interests of our stockholders to restrict the Committee’s discretion and flexibility in developing appropriate compensation programs and thus also consider the competitiveness of our program in our market and the importance to our stockholders of incentivizing and rewarding executives for reaching desired performance levels and other goals.
EMPLOYMENT AGREEMENTS
We have not entered into employment agreements with any of our current executive officers.
EMPLOYMENT SEVERANCE AGREEMENTS
Our board of directors has approved employment severance agreements with all of our senior management personnel, including each of our NEOs. Our board of directors believes it is important to provide our executive officers with severance benefits under limited circumstances to provide them with enhanced financial security and sufficient incentive and encouragement to remain employed by us in the event of a potential change-of-control transaction.
Under the terms of each of the severance agreements, if within three months before or 12 months following a change of control (as defined in the severance agreements), the executive officer’s employment is terminated as a result of (i) an involuntary termination or (ii) a resignation for good reason (each as defined in the severance agreements), then the executive will continue to receive salary at the salary amount in effect at the time of such termination (less applicable withholdings and deductions) for the applicable severance period beginning immediately following such termination, as well as the executive’s target bonus for the year in which the termination occurs. The executive will also vest in and have the right to exercise all outstanding options, restricted stock awards and stock appreciation rights (“SARs”) (in each case, as applicable) that were unvested as of the date of such termination. Additionally, all of our repurchase rights with respect to any vested and unvested restricted stock will lapse and any right to repurchase any of our Common Stock will terminate.
If, within 12 months following a change of control, the executive officer’s employment is terminated as a result of voluntary resignation, termination for cause, disability or death, then the executive officer will not be entitled to receive severance change of control benefits except for those as may be established under our then-existing severance and benefit plans and practices or under other written agreements between us and such executive officer.
Under the terms of each of the severance agreements, upon the termination of the executive officer’s employment for any reason, we will pay the executive:
Any unpaid base salary due for periods prior to the termination date; and
All expenses reasonably and necessarily incurred and submitted on proper expense reports in connection with our business before the termination date.
The severance agreements are substantially identical for each of our current NEOs except that the severance period for Mr. Sheridan is 24 months and the severance period for each of the other NEOs is 18 months.
The benefits payable under the severance agreements may be immediately terminated in certain circumstances, including the unauthorized use by an executive officer of our material confidential information or any prohibited or unauthorized competitive activity undertaken by an executive officer.
