TABLE OF CONTENTS

How does the Board recommend that I vote?

Our Board recommends that you vote your shares:

• “ FOR ” each of the three nominees for Class I director named in this proxy statement;

• “ FOR ” the ratification of the appointment of PwC as our independent registered public accounting firm for our fiscal year ending December 31, 2023; and

• “ FOR ” the advisory non-binding vote to approve the compensation of our named executive officers.

Who is entitled to vote at the annual meeting?

Holders of our common stock as of the close of business on March 17, 2023, the Record Date for the annual meeting, are entitled to vote at the annual meeting. As of the Record Date, there were 60,366,631 shares of our common stock issued and outstanding. Stockholders are not permitted to cumulate votes with respect to the election of directors. Each share of common stock is entitled to one vote on each matter properly brought before the annual meeting.

Stockholder of Record: Shares Registered in Your Name. If, at the close of business on the Record Date for the annual meeting, your shares were registered directly in your name with our transfer agent, American Stock Transfer & Company, LLC, or AST, then you are a stockholder of record. As a stockholder of record, you have the right to grant your voting proxy directly to the individuals listed on the proxy card, to vote electronically at the virtual annual meeting, or by Internet or by telephone, or, if you received paper copies of the proxy materials by mail, to vote by mail by following the instructions on the proxy card or voting instruction card.

Beneficial Owner of Shares Held in “Street Name”: Shares Registered in the Name of a Broker, Bank or Other Nominee. If, at the close of business on the Record Date for the annual meeting, your shares were held not in your name, but rather in an account at a brokerage firm, bank or other nominee, then you are the beneficial owner of shares held in “street name” and the Notice of Internet Availability is being forwarded to you by that organization. The organization holding your account is considered the stockholder of record for purposes of voting at the annual meeting. As a beneficial owner, you have the right to direct your broker, bank or other nominee regarding how to vote the shares in your account by following the voting instructions your broker, bank or other nominee provides. You are also invited to attend the virtual annual meeting. However, since you are not the stockholder of record, you may not vote your shares electronically at the virtual annual meeting unless you obtain a legal proxy from your broker, bank or other nominee.

How can I vote my shares?

Stockholder of Record: Shares Registered in Your Name

If you are a stockholder of record, you may vote in one of the following ways:

• You may vote electronically at the annual meeting . If you plan to attend the virtual annual meeting, you may vote by proxy or electronically at the annual meeting.

• You may vote by mail . To vote by mail, complete, sign and date the proxy card that accompanies this proxy statement and return it promptly in the postage-prepaid envelope provided (if you received printed proxy materials). Your completed, signed and dated proxy card must be received prior to the annual meeting.

• You may vote by telephone . To vote over the telephone, call toll-free 1-800-690-6903 and follow the instructions. Have your Notice of Internet Availability or proxy card available when you call. You will be asked to provide the control number from your Notice of Internet Availability or proxy card. Telephone voting is available 24 hours a day, 7 days a week, until 11:59 p.m., Eastern time, on Tuesday, May 9, 2023.

• You may vote via the Internet . To vote via the Internet, go to www.proxyvote.com to complete an electronic proxy card (have your Notice of Internet Availability or proxy card in hand when you visit the website). You will be asked to provide the control number from your Notice of Internet Availability or proxy card.

TABLE OF CONTENTS

Beneficial Owner of Shares Held in “Street Name”: Shares Registered in the Name of a Broker, Bank or Other Nominee

If you are a beneficial owner of shares held of record by a broker, bank or other nominee, you will receive voting instructions from your broker, bank or other nominee. You must follow the voting instructions provided by your broker, bank or other nominee in order to instruct your broker, bank or other nominee on how to vote your shares. Beneficial owners of shares should generally be able to vote by returning the voting instruction card to their broker, bank or other nominee, or by telephone or via the Internet. However, the availability of telephone or Internet voting will depend on the voting process of your broker, bank or other nominee. As discussed above, if you are a beneficial owner, you may only vote your shares electronically at the annual meeting if you obtain a legal proxy from your broker, bank or other nominee.

Can I change my vote or revoke my proxy?

Stockholder of Record: Shares Registered in Your Name. If you are a stockholder of record, you can change your vote or revoke your proxy by:

• entering a new vote by telephone or via the Internet (until the applicable deadline for each method as set forth above);

• returning a later-dated proxy card (which automatically revokes the earlier proxy);

• providing a written notice of revocation prior to the annual meeting to our corporate secretary at our principal executive offices as follows: BlackLine, Inc., 21300 Victory Boulevard, 12 th Floor, Woodland Hills, California 91367, Attn: Corporate Secretary; or

• attending the virtual annual meeting and voting electronically. Attendance at the virtual annual meeting will not cause your previously granted proxy to be revoked unless you specifically so request or cast your vote electronically at the virtual annual meeting.

Beneficial Owner of Shares Held in “Street Name”: Shares Registered in the Name of a Broker, Bank or Other Nominee. If you are the beneficial owner of your shares, you must contact the broker, bank or other nominee holding your shares and follow their instructions to change your vote or revoke your proxy.

Why did I receive a notice in the mail regarding the Internet availability of the proxy materials instead of a paper copy of the full set of proxy materials?

In accordance with the rules of the Securities and Exchange Commission, or the SEC, we have elected to distribute our proxy materials, including the notice of annual meeting of stockholders, this proxy statement and our 2022 annual report, primarily via the Internet. As a result, we are mailing to our stockholders a Notice of Internet Availability instead of a paper copy of the proxy materials. The Notice of Internet Availability contains instructions on how to access our proxy materials on the Internet, how to vote on the proposals, how to request printed copies of the proxy materials and 2022 annual report, and how to request to receive all future proxy materials in printed form by mail or electronically by e-mail. We encourage stockholders to take advantage of the availability of the proxy materials on the Internet to help reduce our costs and the environmental impact of our annual meetings.

What is the effect of giving a proxy?

Proxies are solicited by and on behalf of our Board. The persons named in the proxy, Mark Partin, our Chief Financial Officer, and Karole Morgan-Prager, our Chief Legal and Administrative Officer and Secretary, have been designated as proxies for the annual meeting by our Board. When proxies are properly dated, executed and returned, the shares represented by such proxies will be voted electronically at the virtual annual meeting in accordance with the instruction of the stockholder on such proxy. If no specific instructions are given, however, the shares will be voted in accordance with the recommendations of our Board on the proposals as described above and, if any other matters are properly brought before the annual meeting, the shares will be voted in accordance with the proxies’ judgment.

How many votes do I have?

Holders of our common stock are entitled to one vote for each share held as of the Record Date.

TABLE OF CONTENTS

What is the quorum requirement for the annual meeting?

A quorum is the minimum number of shares or voting power required to be present or represented at the annual meeting for the meeting to be properly held under our amended and restated bylaws and Delaware law. The presence, virtually or represented by proxy, of a majority of the voting power of our stock issued and outstanding and entitled to vote at the annual meeting will constitute a quorum to transact business at the annual meeting. Abstentions, “WITHHOLD” votes, and “broker non-votes” are counted as present and entitled to vote for purposes of determining a quorum. If there is no quorum, the Chair of the meeting may adjourn the meeting to another time or place.

What are broker non-votes?

Broker non-votes occur when a beneficial owner of shares held in “street name” does not give instructions to the broker, bank or other nominee, as applicable, as to how to vote on matters deemed “non-routine” and there is at least one “routine” matter to be voted upon at the annual meeting. Generally, if shares are held in “street name,” the beneficial owner of the shares is entitled to give voting instructions to the broker, bank or other nominee holding the shares. If the beneficial owner does not provide voting instructions, the broker, bank or other nominee can still vote the shares with respect to matters that are considered to be “routine,” but not with respect to “non-routine” matters. In the event that a broker, bank or other nominee votes shares on the “routine” matters, but does not vote shares on the “non-routine” matters, those shares will be treated as broker non-votes with respect to the “non-routine” proposals. Accordingly, if you own shares through a nominee, such as a broker or bank, please be sure to instruct your nominee how to vote to ensure that your vote is counted on each of the proposals.

What matters are considered “routine” and “non-routine”?

The ratification of the appointment of PwC as our independent registered public accounting firm for our fiscal year ending December 31, 2023 (Proposal No. 2) is considered “routine” under applicable rules. The election of Class I directors (Proposal No. 1), and the advisory non-binding vote to approve the compensation of our named executive officers (Proposal No. 3) are considered “non-routine” under applicable rules.

What are the effects of abstentions and broker non-votes?

An abstention represents a stockholder’s affirmative choice to decline to vote on a proposal. Abstentions will be considered as shares present and entitled to vote at the annual meeting. As a result, abstentions will be counted for purposes of determining the presence or absence of a quorum and will also count as votes against a proposal in cases where approval of the proposal requires the affirmative vote of a majority of the voting power of the shares present virtually or represented by proxy and entitled to vote on the proposal (Proposals No. 2 and No. 3). However, because the outcome of Proposal No. 1 (election of directors) will be determined by a plurality vote, you may only vote “FOR” or “WITHHOLD” and abstentions will have no impact on the outcome of such proposal as long as a quorum exists.

Broker non-votes will be counted for purposes of calculating whether a quorum is present at the annual meeting but will not be counted for purposes of determining the voting power entitled to vote on a proposal. Therefore, a broker non-vote will make a quorum more readily attainable but will not otherwise affect the outcome of the vote on any of the proposals.

What is the voting requirement to approve each of the proposals?

Proposal No. 1: Election of Class I Directors. The election of Class I directors requires a plurality of the voting power of the shares present virtually or represented by proxy at the annual meeting and entitled to vote on the election of directors. This means that the three nominees for Class I director receiving the highest number of “FOR” votes will be elected as Class I directors. You may vote (i) “FOR” for each director nominee or (ii) “WITHHOLD” for each director nominee. Because this is an uncontested election where the number of nominees equals the number of directors to be elected, and the outcome of this proposal will be determined by a plurality vote, shares voted “WITHHOLD” will have no legal effect on the outcome of the proposal. Broker non-votes will not affect the outcome of this proposal.

Proposal No. 2: Ratification of Appointment of PwC. The ratification of the appointment of PwC requires the affirmative vote of a majority of the voting power of the shares present virtually or represented by proxy at

TABLE OF CONTENTS

the annual meeting and entitled to vote on the proposal. You may vote “FOR,” “AGAINST,” or “ABSTAIN” on this proposal. Abstentions will have the same effect as a vote against the proposal. Broker non-votes will not affect the outcome of this proposal.

Proposal No. 3: Advisory Non-Binding Vote to Approve the Compensation of Named Executive Officers . The advisory non-binding vote to approve the fiscal 2022 compensation of our named executive officers requires the affirmative vote of a majority of the voting power of the shares present virtually or represented by proxy at the annual meeting and entitled to vote on the proposal. You may vote “FOR,” “AGAINST,” or “ABSTAIN” on this proposal. Abstentions will have the same effect as a vote against the proposal. Broker non-votes will not affect the outcome of voting on this proposal. Because this vote is advisory only, it will not be binding on our Board. The Compensation Committee will review the voting results and take them into consideration when making future decisions regarding executive compensation.

Who will count the votes?

A representative of Broadridge Financial Solutions will tabulate the votes and act as inspector of elections.

What if I do not specify how my shares are to be voted or fail to provide timely directions to my broker, bank or other nominee?

Stockholder of Record: Shares Registered in Your Name . If you are a stockholder of record and you submit a proxy but you do not provide voting instructions, your shares will be voted:

• “ FOR ” each of the three nominees for Class I director named in this proxy statement;

• “ FOR ” the ratification of the appointment of PwC as our independent registered public accounting firm for our fiscal year ending December 31, 2023; and

• “ FOR ” the advisory non-binding vote to approve the compensation of our named executive officers.

In addition, if any other matters are properly brought before the annual meeting or any adjournments or postponements thereof, the persons named as proxies will be authorized to vote or otherwise act on those matters in accordance with their judgment.

Beneficial Owner of Shares Held in “Street Name”: Shares Registered in the Name of a Broker, Bank or Other Nominee . Brokers, banks and other nominees holding shares of common stock in “street name” for customers are generally required to vote such shares in the manner directed by their customers. In the absence of timely directions, your broker, bank or other nominee will have discretion to vote your shares on our sole “routine” matter—Proposal No. 2 (ratification of the appointment of PwC). Absent direction from you, however, your broker, bank or other nominee will not have the discretion to vote on Proposal No. 1 relating to the election of directors, and Proposal No. 3 relating to the approval of the compensation of our named executive officers.

TABLE OF CONTENTS

Beneficial Owner of Shares Held in “Street Name”: Shares Registered in the Name of a Broker, Bank or Other Nominee . If you were a beneficial owner of shares that are held in “street name” at the close of business on the Record Date, you may not vote your shares electronically at the virtual annual meeting unless you obtain a “legal proxy” from your broker, bank or other nominee who is the stockholder of record with respect to your shares. You may still attend the virtual annual meeting even if you do not have a legal proxy. For admission to the virtual annual meeting, visit www.virtualshareholdermeeting.com/BL2023 and enter the sixteen-digit control number located on your proxy card.

How are proxies solicited for the annual meeting and who is paying for such solicitation?

Our Board is soliciting proxies for use at the annual meeting by means of the proxy materials. We will bear the entire cost of proxy solicitation, including the preparation, assembly, printing, mailing and distribution of the proxy materials. Copies of solicitation materials will also be made available upon request to brokers, banks and other nominees to forward to the beneficial owners of the shares held of record by such brokers, banks or other nominees. The original solicitation of proxies may be supplemented by solicitation by telephone, electronic communication, or other means by our directors, officers or employees. No additional compensation will be paid to these individuals for any such services, although we may reimburse such individuals for their reasonable out-of-pocket expenses in connection with such solicitation. We do not plan to retain a proxy solicitor to assist in the solicitation of proxies.

Where can I find the voting results of the annual meeting?

We will announce preliminary voting results at the annual meeting. We will also disclose voting results on a Current Report on Form 8-K (Form 8-K) filed with the SEC within four business days after the annual meeting. If final voting results are not available to us in time to file a Form 8-K within four business days after the annual meeting, we will file a Form 8-K to publish preliminary results and, within four business days after final results are known, file an amendment to the Form 8-K to publish the final results.

What does it mean if I receive more than one Notice of Internet Availability or more than one set of printed materials?

If you receive more than one Notice of Internet Availability or more than one set of printed materials, your shares may be registered in more than one name and/or are registered in different accounts. Please follow the voting instructions on each Notice of Internet Availability or each set of printed materials, as applicable, to ensure that all of your shares are voted.

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

We have adopted an SEC-approved procedure called “householding,” under which we can deliver a single copy of the Notice of Internet Availability and, if applicable, the proxy materials and annual report, to multiple stockholders who share the same address unless we receive contrary instructions from one or more of the stockholders. This procedure reduces our printing and mailing costs. Stockholders who participate in householding will continue to be able to access and receive separate proxy cards. Upon written or oral request, we will deliver promptly a separate copy of the Notice of Internet Availability and, if applicable, the proxy materials and annual report, to any stockholder at a shared address to which we delivered a single copy of any of these documents. To receive a separate copy, or, if you are receiving multiple copies, to request that we only send a single copy of next year’s proxy materials and annual report, you may contact us as follows:

Our Board is currently comprised of nine members, divided into three classes of directors, each serving staggered three-year terms. Upon expiration of the term of a class of directors, directors in that class will be elected for a three-year term at the annual meeting of stockholders in the year in which that term expires. Each director’s term continues until the election and qualification of his or her successor, or his or her earlier death, resignation or removal. Any increase or decrease in the number of directors will be distributed among the three classes so that, as nearly as possible, each class will consist of one-third of the directors.

Anchor Stockholders’ Agreement

In connection with our initial public offering, we entered into an Amended and Restated Stockholders’ Agreement with Silver Lake Sumeru Fund, L.P., Silver Lake Technology Investors Sumeru, L.P., Iconiq Strategic Partners, L.P., ICONIQ Strategic Partners-B, L.P., Iconiq Strategic Partners Co-Invest, L.P., BL Series and Iconiq Strategic Partners Co-Invest, L.P., BL2 Series, Therese Tucker and Mario Spanicciati (together, the “Stockholder Parties”), dated as of October 27, 2016 (or the “Stockholders’ Agreement”). Pursuant to the Stockholders’ Agreement, only Ms. Tucker continues to beneficially own a sufficient number of shares to designate a designee on our Board. Ms. Tucker will continue to be entitled to membership on our Board for so long as she continues to hold the Designation Threshold as of the Ownership Measurement Date (each as defined in the Stockholder Agreement), provided, however, in the event that Ms. Tucker ceases to be employed by the Company for any reason and she beneficially owns less than the Designation Threshold she will be required to immediately tender her resignation from our Board effective only upon acceptance by our Board, and our Board may, in its sole discretion, accept or reject such resignation. If our Board rejects the resignation, Ms. Tucker will continue to have the right to be designated for membership on our Board; provided that our Board will have the right, by unanimous vote of the other directors (excluding Ms. Tucker), to require her resignation from our Board if our Board determines such resignation would be in the best interests of the Company, regardless of the number of shares of common stock held by Ms. Tucker. The affiliates of each of the Stockholder Parties who continue to hold shares have agreed to vote their shares in favor of Ms. Tucker.

Anchor Director Independence

Our Board believes that it should consist of a substantial majority of independent directors, and has undertaken a review of its composition and the independence of each director. The Board has determined that, except for Mr. Ryan and Ms. Tucker, each of the other seven current directors is independent within the meaning of the listing rules of the Nasdaq Stock Market (Nasdaq). In addition, our Board has undertaken a review of the composition of its committees and has determined that:

• Mr. Thompson, and Mses. Rios and Velastegui, who are members of our Audit Committee, satisfy the enhanced independence standards for Audit Committee members established by applicable SEC and Nasdaq rules.

• Messrs. Thompson, Unterman and Yoran, and Ms. Yamamoto, who are members of our Compensation Committee, satisfy the enhanced independence standards for Compensation Committee members established by applicable SEC and Nasdaq rules.

• Messrs. Unterman and Yoran and Ms. Whye, who are members of our Nominating and Corporate Governance Committee, satisfy the independence standards for Nominating and Corporate Governance Committee members established by applicable Nasdaq rules.

There are no family relationships among any of our directors or executive officers.

Anchor Board Leadership Structure

Our Board has adopted corporate governance guidelines that provide that there will at all times be a majority of independent directors on the Board, as defined by the applicable Nasdaq rules. The guidelines further provide that if the Board does not have an independent Chair, then a Lead Independent Director will be appointed by the Board, which we believe strengthens our governance and the independent role of the Board.

Chair of the Board

From January 2021 to January 2023, Ms. Tucker served as the Executive Chair of the Board, and the individual then serving as our President and Chief Executive Officer was a member of the Board, but did not serve as Chair of the Board. Because Ms. Tucker was not an independent director, during her period of service as Executive Chair, our Board appointed a Lead Independent Director.

In January 2023, Mr. Ryan was appointed Chair of the Board as part of a planned succession of Board leadership. At the time of his appointment, Mr. Ryan was an independent director and therefore the Board did not appoint a Lead Independent Director. When Mr. Ryan was appointed Co-CEO in March 2023, he was no longer an independent director, and accordingly the Board again appointed a Lead Independent Director. The role of the Lead Independent Director is described below. The Chair of the Board determines the agenda and presides over the meetings of the Board and may also call special meetings of the Board. The Chair of the Board also has the power to call special meetings of stockholders, to preside over meetings of the stockholders, and to perform such other duties as may be requested by the Board. The Board believes that having a strong strategic leader as Chair of the Board is important and enables the Board to best oversee and support the strategic direction of the Company.

Lead Independent Director

Graham Smith served as the Lead Independent Director from May 2021 to May 2022, at which time he left our Board in connection with the expiration of his term. Mr. Ryan served as the Lead Independent Director from May 2022 to January 2023, at which time he was elected Chair of the Board. When Mr. Ryan was appointed as Co-CEO, Mr. Unterman was appointed as Lead Independent Director. As a seasoned director with extensive experience as a public company executive and investment professional, Mr. Unterman has experience advising our senior management in key areas and has provided independent oversight in his roles on various committees. Mr. Unterman brings continuity to our Board and has been appointed as Lead Independent Director due to his experience as a strong independent leader. The Lead Independent Director determines the agenda and presides over the meetings of the independent directors, serves as a liaison between the independent directors and the non-independent directors, including the Co-CEOs, serves as spokesperson for the Company as requested, and as the majority of the independent directors may determine from time to time.

TABLE OF CONTENTS

The Board believes that this leadership structure, coupled with a strong emphasis on board independence, provides effective independent oversight of management while allowing both the Board and management to benefit from Mr. Ryan's leadership and years of experience in the technology industry. We believe the expertise of Mr. Ryan and Mr. Unterman serving in Board leadership roles and Mr. Ryan now as Co-CEO, together with the outside experience, oversight, and expertise of our independent directors, allows for different perspectives and facilitates effective strategy development that benefits our stockholders. This structure enables Mr. Ryan to act as the key link between the Board and other members of management. Further, the Board believes that Mr. Ryan's combined role enables decisive leadership in management and on the Board, ensures strategic and operational direction and enhances the Company's ability to communicate its message and strategy clearly and consistently to its stockholders, employees, customers and partners. At this time, the Board believes that stockholders are best served by this leadership structure.

Anchor Role of Board in Risk Oversight Process

Risk is inherent with every business, and we face a number of risks, including strategic, financial, business and operational, legal and compliance, and reputational. We have designed and implemented processes to manage risk in our operations, including longer term risks as well as near term risks and potential business continuity risks. Management is responsible for the day-to-day management of risks the Company faces, while our Board, as a whole and assisted by its committees, has responsibility for the oversight of risk management. Our Board reviews strategic and operational risk in the context of discussions, question and answer sessions, and reports from the management team at each regular Board meeting, receives reports on all significant committee activities at each regular Board meeting, and evaluates the risks inherent in significant transactions. In its assessment of risks and risk management, our Board and its committees consult with outside advisors, including the Company's independent auditors, legal counsel and the compensation consultant engaged by the Compensation Committee. Our Audit Committee assists our Board in fulfilling its oversight responsibilities with respect to oversight of risk assessment and risk management generally, and specifically in the areas of internal control over financial reporting and disclosure controls and procedures, legal and regulatory compliance, cybersecurity risk, and also, among other things, discusses guidelines with management and the independent auditor. Our Nominating and Corporate Governance Committee assists our Board in fulfilling its oversight responsibilities with respect to risks relating to our corporate governance practices, the independence of the Nominating and Corporate Governance Committee and potential conflicts of interest, as well as our policies and practices with regard to environmental, social and governance matters. In addition, as part of its oversight of the composition of our Board, our Nominating and Corporate Governance Committee takes into account the Company's business, risks and strategies to determine the appropriate expertise needed on our Board. Our Compensation Committee assesses risks relating to our executive compensation plans and arrangements, and whether our compensation policies and programs have the potential to encourage excessive risk taking.

Our Board believes its current leadership structure supports the risk oversight function of the Board. In particular, our Board believes that our lead independent director and our majority of independent directors provide a well-functioning and effective balance to the members of executive management and employees on our Board. Further, our Board and Compensation Committee review and discuss with management matters related to human capital management, including our commitments and progress on inclusion and diversity, employee engagement, compensation and benefits, business conduct and compliance, and executive succession planning. During 2022, the Board and its committees also reviewed and discussed with management on a regular basis the impact of the COVID-19 pandemic and unfavorable macroeconomic trends on BlackLine’s operations, as well as management’s strategies and initiatives to respond to and mitigate adverse impacts of the pandemic and economic uncertainty, such as risks related to continuing remote work by us and our customers, economic risk, longer sales cycles, and the impacts of continuing virtual customer events and remote sales activities.

Anchor Board Meetings and Committees

During our fiscal year ended December 31, 2022, our Board held twelve meetings (including regularly scheduled and special meetings), and each director attended at least 75% of the aggregate of (i) the total number of meetings of our Board held during the period for which he or she has been a director and (ii) the total number of meetings held by all committees of our Board on which he or she served during the periods when he or she served. We do not have a formal policy regarding attendance by members of our Board at annual meetings of stockholders, but we strongly encourage our directors to attend. A majority of the then-serving directors attended our 2022 annual meeting of stockholders.

Anchor Considerations in Evaluating Director Nominees

In its evaluation of director candidates, including the members of the Board eligible for re-election, our Nominating and Corporate Governance Committee considers the current size and composition of the Board, the needs of the Board and its respective committees, the directors nominated or designated in accordance with the Stockholders’ Agreement, if applicable, and the desired board qualifications, expertise and characteristics, including such factors as business experience and diversity. While we do not have a formal policy with respect to diversity, our Nominating and Corporate Governance Committee may consider such factors as differences in professional background, education, skill, race, ethnicity, gender, age and other individual characteristics, qualities and attributes that contribute to the total mix of viewpoints and experience represented on the Board. Our Board is committed to seeking out highly qualified women and individuals from underrepresented communities and diverse backgrounds, and we will comply with any applicable law or other requirement in this regard. Our Nominating and Corporate Governance Committee has engaged an executive search firm to assist in identifying and recruiting potential candidates for membership on our Board.

Our Nominating and Corporate Governance Committee evaluates each individual in the context of the membership of the Board as a group, with the objective of having a group that can best perpetuate the success of the business and represent stockholder interests with high character and integrity, and the exercise of sound judgment using its diversity of background and experience in various areas. The Board annually evaluates the performance of the Board and its committees. Our Nominating and Corporate Governance Committee reviews self-assessment questionnaires to evaluate the performance of individual members. In determining whether to recommend a director for re-election, our Nominating and Corporate Governance Committee also considers the director’s past attendance at meetings, participation in and contributions to the activities of the Board and the Company, and other qualifications and characteristics determined by the Board. Each director must ensure that other existing and anticipated future commitments do not materially interfere with his or her service as a director.

After completing its review and evaluation of director candidates, in accordance with the rules of Nasdaq, our Nominating and Corporate Governance Committee will recommend a director nominee for selection by our Board. Our Board has the final authority in determining the selection of director candidates for nomination to our Board.

Anchor Stockholder Recommendations for Nominations to Our Board

A stockholder that wants to recommend a candidate for election to the Board should direct the recommendation in writing by letter to the Company, attention of our Chief Legal and Administrative Officer at BlackLine, Inc., 21300 Victory Boulevard, 12 th Floor, Woodland Hills, California 91367. Such recommendation should include the candidate’s name, home and business contact information, detailed biographical data and relevant qualifications, a signed letter from the candidate confirming willingness to serve, information regarding any relationships between us and the candidate, and evidence of the recommending stockholder’s ownership of our stock. Such recommendation should also include a statement from the recommending stockholder in support of the candidate, particularly within the context of the criteria for Board membership. We do not have a formal policy regarding the consideration of director candidates recommended by stockholders, but subject to the foregoing, our independent directors will consider candidates recommended by stockholders in the same manner as candidates recommended from other sources. Our independent directors have discretion to decide which individuals to recommend for nomination as directors.

TABLE OF CONTENTS

12 th Floor, Woodland Hills, California 91367. Our Chief Legal and Administrative Officer will, in consultation with appropriate directors as necessary, review incoming stockholder communications and decide whether a response to any stockholder or interested party communication is necessary.

This procedure does not apply to (i) communications to non-management directors from our officers or directors who are stockholders or (ii) stockholder proposals submitted pursuant to Rule 14a-8 under the Securities Exchange Act of 1934, as amended, or the Exchange Act, which are discussed further in the section entitled “ Stockholder Proposal Deadlines for 2024 Annual Meeting” in this proxy statement.

Anchor Code of Business Conduct and Ethics

Our Board has adopted a written code of business conduct and ethics that applies to all of our employees, officers and directors, including our Co-CEOs, Chief Financial Officer, and other executive and senior financial officers. The full text of our code of business conduct and ethics is available on the corporate governance section of our website, which is located at http://investors.blackline.com. We intend to disclose any amendments to our code of business conduct and ethics, or waivers of its requirements, on our website or in filings under the Exchange Act. We are committed to maintaining high standards of financial integrity, open communication, and a workplace environment where employees can raise concerns free of harassment, discrimination or retaliation. We maintain a formal whistleblower policy which describes the means by which employees, directors and officers can report suspected violations of our code of business conduct and ethics. Reports of suspected violations may be made directly to human resources or the legal department, or through our reporting hotline, which allows anonymous reporting where permitted by law. Retaliation is strictly prohibited under both our code of business conduct and ethics and our whistleblower policy.

Anchor Director Stock Ownership Guidelines

In February 2020, the Compensation Committee and the Nominating and Corporate Governance Committee recommended, and our Board approved, stock ownership guidelines for our directors. Under these guidelines, each director is expected to attain minimum levels of stock ownership equal to 4x the director’s annual cash retainer for service on our Board (not including any additional fees received for committee service or serving as a Chair of a committee). For purposes of this requirement, shares counted toward these guidelines include any shares outright, and in-the-money value of vested but unexercised stock options. The value for purposes of satisfying this requirement is the 90-day trailing average of the closing price of our common stock as of the last trading day of the fiscal year prior to the compliance date. Directors have until the later of February 2025 or, if applicable, the fifth anniversary of the date they join our Board to attain the requisite level of ownership. If a director does not achieve the minimum level of ownership by the director’s compliance date, then 50% of the after-tax value of the director’s exercised options or vested RSUs will be retained until the minimum level of ownership for the director is met. As of December 31, 2022, five of our six non-employee directors had exceeded their requisite level of stock ownership under the guidelines.

Anchor Corporate Responsibility and Sustainability

BlackLine recognizes the importance of a thoughtful approach to corporate citizenship, and this is reflected in our Board's oversight of our environmental, social, and governance (“ESG”) programs. Our Nominating and Corporate Governance Committee oversees our programs relating to corporate responsibility and sustainability, including environmental, social, and corporate governance matters, and our Compensation Committee oversees our efforts to promote diversity and inclusion in our workforce, and management's efforts to foster a corporate culture in alignment with the Company's values and strategy.

During 2022, BlackLine's ESG committee continued its work of steering and reporting on BlackLine's ESG strategy and programs, with executive sponsorship and participation from our Chief Legal and Administrative Officer. As we continue to develop our ESG strategies and practices, we are also committed to growing and refining our programs using a stakeholder-focused approach. Our current programs include:

• Community Involvement. We drive social good through our commitment to responsible corporate citizenship across the communities in which we operate. We offer employer-matched charitable giving, and promote volunteer opportunities with local organizations such as the Los Angeles Regional Food Bank. Our charitable efforts are focused on three key areas that are shaped by BlackLine’s values and commitment to responsible corporate citizenship:

Diversity, equity and inclusion (“DEI”) are deeply rooted in our culture, and we continue to support this with a company-wide objective to strengthen our culture of diversity, equity, and inclusion in order to develop an agile, diverse, inclusive, and highly engaged workforce. Programs that advance our DEI strategy include employee training to reduce unconscious bias in the workplace, employee recruitment of underrepresented communities, and our employee-led and executive sponsored Employee Resource Groups, designed to help build community and foster a diverse and inclusive workplace by providing networking and team-building opportunities.

• Compliance with Laws. BlackLine is committed to complying with all applicable laws in all jurisdictions where it does business, including employment, human rights, and environmental laws and regulations.

• Health and Safety. BlackLine is committed to supporting the wellbeing of its employees around the world, and has continued to take a proactive approach to helping our employees remain healthy and productive.

Anchor COMPENSATION OF NON-EMPLOYEE DIRECTORS

Anchor Outside Director Compensation Policy

Members of our Board who are not employees are eligible for compensation under our Outside Director Compensation Policy, adopted in 2016 in connection with our initial public offering and amended in December 2022 to adjust certain cash retainer fees and reflect changes in the leadership structure of our Board. Accordingly, neither Ms. Tucker nor Mr. Huffman, each an employee of BlackLine in 2022, was eligible for awards under our Outside Director Compensation Policy for 2022, and neither Ms. Tucker nor Mr. Ryan, each an employee of BlackLine in 2023, is eligible for awards under our Outside Director Compensation Policy for 2023.

The Outside Director Compensation Policy was developed in consultation with Compensia, Inc., an independent compensation consulting firm, or Compensia. Compensia provided recommendations and competitive non-employee director compensation data and analyses. Our Board considered and discussed these recommendations and data, and considered the specific duties and committee responsibilities of particular directors. Our Board adopted Compensia’s recommendations when it approved our Outside Director Compensation Policy, which we believe provides our non-employee directors with reasonable and appropriate compensation that is commensurate with the services they provide and competitive with compensation paid by our peer group companies to their non-employee directors.

The Compensation Committee periodically reviews the type and form of compensation paid to our non-employee directors, which includes a market assessment and analysis by Compensia. As part of this analysis, Compensia reviews non-employee director compensation trends and data from companies comprising the same executive compensation peer group used by the Compensation Committee in connection with its review of executive compensation.

Under our Outside Director Compensation Policy as in effect for fiscal year 2022, non-employee directors received compensation in the form of equity and cash, as described below:

Cash Compensation

During fiscal year 2022, each non-employee director was eligible to receive the following annual cash retainers for certain Board and/or committee service:

Board/Committee			Member ($)
Board			40,000
Audit Committee			10,000
Compensation Committee			7,500
Nominating and Corporate Governance Committee			4,000

Each non-employee director serving as Lead Independent Director or a committee Chair was eligible to receive the following additional cash retainers:

Lead Independent Director: $30,000

Audit Committee Chair: $20,000

Compensation Committee Chair: $15,000

Nominating and Corporate Governance Committee Chair: $8,000

All cash payments to non-employee directors are paid quarterly in arrears on a prorated basis. 6

6 On December 30, 2022, our Outside Director Compensation Policy was amended to provide that each non-employee director serving as Lead Independent Director or a committee Chair is eligible to receive the following annual cash retainers, effective for service on and after January 1, 2023:

Chair of the Board: $43,000

Lead Independent Director: $30,000

Audit Committee Chair: $20,000

Compensation Committee Chair: $15,000

Nominating and Corporate Governance Committee Chair: $8,000

Equity Compensation

Non-employee directors are eligible to receive all types of equity awards (except incentive stock options) under our 2016 Equity Incentive Plan, or the 2016 Plan, (or the applicable equity plan in place at the time of grant) including discretionary awards not covered under our Outside Director Compensation Policy. All grants of awards under our Outside Director Compensation Policy are automatic and nondiscretionary.

Initial Award

During fiscal year 2022, upon joining our Board, a newly-elected non-employee director would receive an initial equity award having a grant date fair value equal to $185,000 multiplied by a fraction, (1) the numerator of which is (x) 12 minus (y) the number of full months between the date of the last annual meeting of stockholders and the date the individual becomes a member of the Board and (2) the denominator of which is 12 (rounded to the nearest whole share), or the Initial Award. The Initial Award was comprised of restricted stock units, or RSUs. The Initial Award is granted on the date on which such person first becomes a non-employee director.

Subject to the terms of the policy, the Initial Award vests as to 100% of the shares subject thereto upon the earlier of the one-year anniversary of the grant date or the day prior to our next annual meeting of stockholders, subject to the individual’s continued service through the applicable vesting date. An employee director who ceases to be an employee but remains a director will not receive an Initial Award.

Annual Award

On the date of our annual meeting of our stockholders, each non-employee director automatically was granted an equity award having a grant date value equal to $185,000, or the Annual Award subject to such individual continuing to be an outside director. The Annual Award was comprised of RSUs. Subject to the terms of the policy, each Annual Award vests as to 100% of the shares subject thereto upon the earlier of the one-year anniversary of the grant date or the day prior to our next annual meeting occurring after the grant date, subject to the individual’s continued service through the applicable vesting date.

The grant date value of all equity awards granted under our Outside Director Compensation Policy is determined in accordance with accounting principles generally accepted in the United States of America.

Any award granted under our Outside Director Compensation Policy will fully vest in the event of a change in control, as defined in our 2016 Plan, provided that the individual remains a director through such change in control.

Anchor Director Compensation Table

The following table provides information regarding compensation of our non-employee directors for service as directors, for the year ended December 31, 2022. The Company reimburses each outside director’s reasonable, customary and properly documented travel expenses to attend Board meetings.

Anchor PROPOSAL NUMBER 1

ELECTION OF CLASS I DIRECTORS

Our Board is currently comprised of nine directors and is divided into three staggered classes of directors. At the annual meeting, three Class I directors will be elected to our Board by the holders of our common stock to succeed the same class whose term is then expiring. Each director’s term continues until the expiration of the term for which such director was elected and until such director’s successor is elected and qualified or until such director’s earlier death, resignation or removal.

Anchor Nominees for Director

Our Nominating and Corporate Governance Committee has recommended to our Board, and upon such recommendation, our Board has nominated Ms. Tucker and Messrs. Unterman and Yoran for re-election as Class I directors at the 2023 annual meeting of stockholders. Mr. Yoran is standing for election by stockholders for the first time. He was initially recommended for consideration as a director by the Nominating and Corporate Governance Committee by a third-party search firm. If elected, Ms. Tucker and Messrs. Unterman and Yoran will serve as Class I directors until the 2026 annual meeting and until their respective successors are duly elected and qualified, or until their earlier death, resignation or removal. For more information concerning the nominees, please see the section entitled “ Board of Directors and Corporate Governance .”

Ms. Tucker and Messrs. Unterman and Yoran have agreed to serve as directors if elected, and management has no reason to believe that they will be unavailable to serve. If a nominee is unable or declines to serve as a director at the time of the annual meeting, proxies will be voted for any nominee who may be proposed by our Nominating and Corporate Governance Committee and designated by the present Board to fill the vacancy.

Anchor Required Vote

The Class I directors will be elected by a plurality of the voting power of the shares present virtually or represented by proxy at the annual meeting and entitled to vote on the election of directors. In other words, the three nominees receiving the highest number of “FOR” votes will be elected as Class I directors. You may vote (i) “FOR” for each director nominee or (ii) “WITHHOLD” for each director nominee. Shares represented by executed proxies will be voted, if authority to do so is not expressly withheld, for the election of Ms. Tucker and Messrs. Unterman and Yoran. “WITHHOLD” votes and broker non-votes will have no effect on the outcome of this proposal.

Anchor Board Recommendation

Our Board recommends a vote “FOR” the election to the Board of Therese Tucker, Thomas Unterman and Amit Yoran as Class I directors.

Anchor PROPOSAL NUMBER 2

RATIFICATION OF APPOINTMENT OF INDEPENDENT

REGISTERED PUBLIC ACCOUNTING FIRM

Our Audit Committee has appointed PricewaterhouseCoopers LLP, or PwC, as our independent registered public accounting firm for the year ending December 31, 2023. During 2022, PwC served as our independent registered public accounting firm.

Notwithstanding its appointment and even if our stockholders ratify the appointment, our Audit Committee, in its discretion, may appoint another independent registered public accounting firm at any time during the year if the Audit Committee believes that such a change would be in the best interests of the Company and its stockholders. Our Audit Committee is submitting the appointment of PwC to our stockholders because we value our stockholders’ views on our independent registered public accounting firm and as a matter of good corporate governance. If the appointment is not ratified by our stockholders, our Audit Committee may consider whether it should appoint another independent registered public accounting firm. A representative of PwC is expected to be telephonically present at the virtual annual meeting, where he or she will be available to respond to appropriate questions and, if he or she desires, to make a statement.

Anchor Fees Paid to the Independent Registered Public Accounting Firm

The following table presents the aggregate fees billed for professional audit services and other services rendered to us by PwC for our fiscal years ended December 31, 2022 and 2021.

	Fiscal Year Ended — 2022	2021
Audit Fees (1)	$2,794,000	$2,420,000
Audit-related Fees (2)	—	320,000

All Other Fees	12,900	12,900
Total Fees	$2,873,400	$3,173,232

(1) “Audit Fees” consist of professional services rendered in connection with the audit of our consolidated financial statements and review of our quarterly consolidated financial statements and services that are normally provided by the independent registered public accounting firm in connection with statutory and regulatory filings or engagements for those fiscal years. Fees for 2022 also included fees billed for professional services rendered in connection with our Form S-8 registration statement in February 2023. Fees for 2021 also included fees billed for professional services rendered in connection with our Form S-8 registration statement in February 2022, as well as equity evaluation for certain of our foreign employees.

(2) For 2021, “Audit related Fees” include fees related to the acquisition of FourQ Systems, Inc.

(3) “Tax Fees” consist of fees for professional services for tax compliance, tax advice and tax planning.

Anchor Auditor Independence

In 2022, there were no other professional services provided by PwC that would have required our Audit Committee to consider their compatibility with maintaining the independence of PwC.

Anchor Audit and Non-Audit Services Pre-Approval Policy

Our Audit Committee has established a policy governing our use of the services of our independent registered public accounting firm. Under this policy, our Audit Committee (or its delegate) may pre-approve services to be performed by our independent registered public accounting firm without consideration of specific case-by-case services or may require the specific pre-approval of the committee, in either case, in order to ensure that the provision of such services does not impair the public accountants’ independence. All fees paid to PwC for our fiscal years ended December 31, 2022 and 2021 were pre-approved by our Audit Committee.

Anchor Required Vote

Ratification of the appointment of PwC as our independent registered public accounting firm for the year ending December 31, 2023 requires the affirmative “FOR” vote of a majority of the voting power of the shares present virtually or represented by proxy at the annual meeting and entitled to vote on the proposal.

Anchor Audit Committee Report

BlackLine’s management is responsible for (i) establishing and maintaining internal controls and (ii) preparing BlackLine’s consolidated financial statements. BlackLine’s independent registered public accounting firm, PwC, is responsible for performing an independent audit of BlackLine’s consolidated financial statements and BlackLine’s internal control over financial reporting in accordance with the auditing standards of the Public Company Accounting Oversight Board (United States), or the PCAOB, and to issue a report thereon. It is the responsibility of the Audit Committee to oversee these activities. It is not the responsibility of the Audit Committee to prepare BlackLine’s financial statements. These are the fundamental responsibilities of management. In the performance of its oversight function, the Audit Committee has:

• reviewed and discussed the audited financial statements for fiscal year 2022 with the management of BlackLine and PwC;

• discussed with PwC the matters required to be discussed by the applicable requirements of the PCAOB; and

• received the written disclosures and the letter from PwC as required by applicable requirements of the PCAOB regarding the independent registered public accounting firm’s communications with the Audit Committee concerning independence, and has discussed with PwC that firm’s independence.

Based on the Audit Committee’s review of the audited financial statements and the various discussions with management and PwC, the Audit Committee recommended to the Board that the audited financial statements be included in our annual report on Form 10-K for the fiscal year ended December 31, 2022 for filing with the SEC. The Audit Committee has also appointed PwC as the Company’s independent registered public accounting firm for the year ending December 31, 2023.

ADVISORY NON-BINDING VOTE TO APPROVE THE COMPENSATION OF

NAMED EXECUTIVE OFFICERS

Our Board is asking Company stockholders to cast an advisory, non-binding vote to approve the compensation of our named executive officers during 2022 as disclosed in this proxy statement in accordance with the requirements of Section 14A of the Exchange Act. This Proposal gives our stockholders the opportunity to express their views on the design and effectiveness of our executive compensation program.

Anchor Advisory Vote on Compensation of Named Executive Officers

We believe that BlackLine’s compensation philosophy and program, as described below in the “Compensation Discussion and Analysis” section of this proxy statement, are effective in achieving our goals, and that the executive compensation reported in this proxy statement is appropriate, competitive, and aligned with our 2022 results. The compensation program for our named executive officers is focused on pay-for-performance principles. The program is designed to attract, motivate, and retain executive officers in a competitive market for executive talent, reward them with more than base salary if and to the extent BlackLine achieves challenging financial performance goals, and align the officers’ interests with the interests of our stockholders to create long-term shareholder value, while at the same time avoiding the encouragement of excessive risk-taking.

For a more detailed discussion of our compensation philosophy, objectives, principles, and programs, we strongly encourage our stockholders to review this proxy statement, and in particular the information contained in the “Compensation Discussion and Analysis” section below and in the compensation tables and narrative that follow it in the “Executive Compensation” section of this proxy statement.

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

Our Board believes that it is in the best interests of the Company and our stockholders to approve the 2022 compensation of our named executive officers, thereby encouraging them to remain in the Company’s employ and more closely align their interests with those of our stockholders.

Anchor Required Vote

The vote is advisory, which means that the vote is not binding on BlackLine, our Compensation Committee, or our Board. Abstentions are considered votes cast, and thus, will have the same effect as votes “against” the proposal. Broker non-votes will have no effect on the outcome of this proposal. Although the vote is non-binding, our Compensation Committee and Board value your opinion and will consider the outcome of the vote in making future compensation decisions.

Anchor Board Recommendation

Our Board recommends an advisory non-binding vote “FOR” the proposal to approve the 2022 compensation of our named executive officers.

Anchor Compensation Discussion and Analysis

The following Compensation Discussion and Analysis describes our executive compensation program and the material elements of our 2022 compensation program applicable to our named executive officers, or NEOs.

The purpose of this section is to provide a detailed discussion of our executive compensation program, policies, practices, and related corporate governance. This section is designed to assist our stockholders in understanding the approach we take to executive compensation, including how our program is designed and linked to our financial performance, and how our executive compensation practices align with the evolution of our business and organizational culture.

Our NEOs for 2022 are:

Therese Tucker , current Co-Chief Executive Officer (“Co-CEO”) and former Executive Chair

Marc Huffman , former President and former Chief Executive Officer (“CEO”)

Mark Partin , Chief Financial Officer (“CFO”)

Karole Morgan-Prager , Chief Legal and Administrative Officer (“CLAO”)

Mark Woodhams , Chief Revenue Officer (“CRO”)

Management Changes

Effective as of January 1, 2023, Ms. Tucker, our founder and former Chief Executive Officer, transitioned from her role as Executive Chair of the Board, and Mr. Ryan, who had been serving as Lead Independent Director, assumed the role of Chair of the Board. At that time, Ms. Tucker continued to serve as a member of the Board and as an employee of the Company. Effective as of March 6, 2023, Mr. Huffman ceased to serve as our President and Chief Executive Officer, and Ms. Tucker and Mr. Ryan were appointed as our Co-CEOs. Following this transition, Ms. Tucker and Mr. Ryan continue to serve as members of our Board, and Mr. Ryan continues to serve as Chair of the Board.

Fiscal Year 2022 Business Highlights

In fiscal year 2022, we delivered strong results from a financial and operational standpoint, as highlighted by the following:

• Total GAAP Revenue grew to $522.9 million, an increase of 23% over the prior year.

• GAAP net loss was $29.4 million, or $0.49 per basic and diluted share.

• Non-GAAP net income attributable to BlackLine was $46.2 million, or $0.64 per diluted share.

• Operating cash flow was $56.0 million, a decrease of 30% over the prior year.

• Free cash flow was $25.7 million, a decrease of 54% over the prior year.

• On January 26, 2022, we completed our acquisition of FourQ Systems, Inc., a leader in intercompany financial management technology.

Please see Appendix A to this proxy statement for a reconciliation of GAAP and non-GAAP net income and free cash flow.

Our Business

Our mission is to transform how finance and accounting departments operate by modernizing accounting through unifying data and processes, automating repetitive work, and driving accountability through visibility. We have created a comprehensive cloud-based software platform designed to automate, centralize, and streamline financial close operations and other key Finance & Accounting processes for large and midsize organizations.

Our Compensation Philosophy

We are committed to developing a compensation program that rewards our executives in direct alignment with the achievement of both near- and long-term business and strategic objectives (i.e., pay-for-performance). In furtherance of this objective, our Compensation Committee routinely considers appropriate adjustments to the

TABLE OF CONTENTS

design of our compensation program to reflect our strategic direction and evolving needs of our business. Additionally, our Compensation Committee seeks to set compensation levels for our executive officers at competitive levels so that we can attract, retain, and motivate highly qualified executives to contribute to our success. In assessing the overall compensation for executive officers, the Compensation Committee generally considers our financial performance, stockholder returns and position vs. selected peers, market compensation data, executive’s performance, awards given in previous years, and recommendations of our independent consultant.

When making executive compensation decisions, the Compensation Committee is guided by the following principles:

• Attracting and retaining senior executives with the right expertise necessary to achieve our strategic objectives and grow our organization

• Paying for performance to ensure that a significant portion of executives’ compensation is realized when the organization meets its financial results

• Aligning interests of our executives with stockholders to ensure that executives’ compensation payouts align with the achievement of results that are correlated with long-term value and stock price appreciation

• Rewarding achievement by providing appropriate levels of awards for attaining both short-term and long-term financial results

Our 2022 executive compensation program consisted of the following core elements:

• base salary;

• annual cash bonuses;

• long-term equity compensation (RSUs and stock options); and

• retirement and health benefits on the same terms as for similarly situated non-executive employees.

2022 Executive Compensation Highlights

	COMPENSATION HIGHLIGHT		UNDERLYING PHILOSOPHY/CONSIDERATIONS
	Pay-for-performance alignment		•		We strive to maintain a pay-for-performance alignment by allocating a meaningful
portion of the overall compensation opportunity for our NEOs in the form of performance-based compensation that is at risk and directly tied to specific financial objectives.
			•		Our performance-based compensation philosophy seeks to align the interests of our
NEOs to the interests of our stockholders.
	Alignment of performance metrics with key strategic
objectives		•		Identifying and selecting the right performance metrics for our performance-based
compensation is key to incentivizing our executives to achieve our strategic plan, which promotes the interest of our stockholders.
			•		In 2022, our strategic focus was to grow our top-line toward profitability. With
this in mind, we selected key performance metrics for the 2022 annual cash bonus plan to drive top-line performance: revenue and non-GAAP net income, and changed the mix our equity awards to our NEOs to eliminate stock options and to
include performance-based RSU awards vesting on satisfaction of revenue, annualized recurring revenue and non-GAAP net income.
	Market-based base salary increases		•		We adjusted the base salaries of each of our NEOs in 2022, in each case to better
align their base salaries with our competitive market and their expected contributions to our business.

	COMPENSATION HIGHLIGHT		UNDERLYING PHILOSOPHY/CONSIDERATIONS
	Continued focus on executive recruitment and retention		•		While we seek to develop our executive compensation program so that it closely
aligns with our pay-for-performance philosophy and rewards achievement of performance goals, this objective must complement other important objectives, including the hiring and retention of executives.
			•		To improve recruitment and strengthen retention, we continued our practice in
2022 of granting each NEO a portion of their annual equity awards in RSUs that vest solely over a time-based schedule and are not tied to company performance with the remaining portion of their annual equity awards granted in PSUs as
discussed below.
			•		The significant decrease in market prices throughout the industry, including at
the Company, resulted in the value of our NEOs’ unvested equity awards having decreased retention value. With the advice of the Compensation Committee’s independent compensation consultants, we made additional retention grants in December
2022 to each of our NEOs (in January 2023 for Ms. Tucker). These consisted of RSUs that vest over a time-based schedule for all NEOs other than Mr. Huffman, and PSUs that vest over a time-based schedule but subject to satisfaction of
long-term performance conditions that are aligned to our long-range plan for Mr. Huffman. The grant to Mr. Huffman was entirely performance-based and was based on longer-term performance goals, responding to some concern that our prior
PSU only had performance targets for one-year goals. The entirely performance-based grant makes up substantially all of the difference between Mr. Huffman’s 2021 and 2022 equity grant value.
	Strong Stockholder Support for our executive compensation
programs		•		At the 2022 annual meeting, over 94% of advisory votes cast by our stockholders
were in favor of our NEOs’ 2021 compensation. We believe that the results of this vote affirm our stockholders’ support of our approach to executive compensation.

Pay-for-Performance Discussion

Our executive compensation program is reasonable, competitive, and rigorously balances the goals of attracting, motivating, rewarding, and retaining our NEOs. To ensure our NEOs’ interests are aligned with those of our stockholders and to motivate and reward individual initiative and effort, a substantial portion of their annual target total direct compensation opportunity is “at-risk” and the actual amounts payable to our NEOs will vary above or below target levels commensurate with our performance.

We emphasize performance-based compensation that appropriately rewards our NEOs for delivering financial, operational, and strategic results that meet or exceed pre-established goals through our cash bonus plan and equity awards.

For SEC-mandated disclosure on pay versus performance for our CEO and other NEOs, please see the “Pay Versus Performance” section below.

Executive Compensation Policies and Practices

We maintain sound governance standards consistent with our executive compensation policies and practices. The Compensation Committee evaluates our executive compensation program regularly to ensure that it supports our short-term and long-term goals given the dynamic nature of our business and the market in which we compete for executive talent. These policies and practices were in effect during 2022:

What we do

✔ Independent Compensation Committee Advisor . The Compensation Committee engaged its own independent compensation consultant to assist with the design of the 2022 executive compensation program.

✔ Annual Executive Compensation Review . The Compensation Committee conducts an annual review of compensation for our NEOs and a review of compensation-related risks.

✔ Compensation At-Risk . The executive compensation program is designed so that a significant portion of executive annual compensation is “at risk” to align the interests of our NEOs and our stockholders. The 2022 Bonus Plan achievement for our NEOs was 82.00% of target based on the challenging goals set by the Compensation Committee and its review of our performance.

✔ Multi-Year Vesting Requirements . The equity awards granted to our NEOs vest over multiple years and generally no portion of these awards vests until approximately 12 months after the grant date, consistent with current market practice and our retention objectives.

✔ Limited Perquisites . We provide minimal perquisites and other personal benefits to our NEOs, except where they serve a legitimate business purpose.

✔ Stock Ownership Guidelines . We have robust stock ownership guidelines in order to encourage stock ownership among our directors and executive officers.

What we don’t do

✗ No “Golden Parachute” Tax Reimbursements . We do not provide any tax reimbursement payments (including “gross-ups”) on any tax liability that our NEOs might owe as a result of the application of Sections 280G or 4999 of the Internal Revenue Code (the “Code”).

✗ No Stock Options Granted with an Exercise Price Less Than Fair Market Value . All stock options are granted with an exercise price at the closing market price on the grant date.

✗ No Special Retirement Plans . We do not offer, nor do we have plans to provide, pension arrangements, retirement plans or nonqualified deferred compensation plans or arrangements exclusively to our NEOs.

✗ No Special Health and Welfare Benefits . Our NEOs participate in the same Company-sponsored health and welfare benefits programs as our other full-time, salaried employees.

✗ No “Single Trigger” Change of Control Arrangements . No change of control payments or benefits are triggered simply by the occurrence of a change of control. All change-of-control payments and benefits are based on a “double-trigger” arrangement (that is, they either require both a change of control of the Company plus a qualifying termination of employment before payments and benefits are paid or, in the case of certain performance awards, require a change of control of the Company and the award is not assumed in the acquisition).

✗ No Hedging or Pledging . We have a policy that restricts employees from hedging our securities or pledging our securities as collateral.

Anchor Governance of Executive Compensation Program

Role of the Compensation Committee

The Compensation Committee discharges the responsibilities of our Board relating to the compensation of our NEOs. With respect to our NEOs, the Compensation Committee reviews and approves at the beginning of the year, or more frequently as warranted, their annual base salaries; cash bonus opportunities and cash bonus payments; long-term equity incentive compensation; employment offers (including post-employment compensation arrangements); and other compensation, perquisites, and other personal benefits, if any.

The Compensation Committee’s practice of developing and maintaining compensation arrangements that are competitive includes a balance between hiring and retaining the best possible talent and maintaining a reasonable and responsible cost structure.

Compensation-Setting Process

We do not establish a specific target for setting the target total direct compensation opportunity of our NEOs. When determining and setting the amount of each compensation element, the Compensation Committee considers the following factors:

• our performance against the financial and operational objectives established by the Compensation Committee and our Board;

• each individual NEO’s skills, experience, and qualifications relative to other similarly situated executives at the companies in our compensation peer group;

• the scope of each NEO’s role compared to other similarly situated executives at the companies in our compensation peer group;

• the performance of each individual NEO, based on a subjective assessment of his or her contributions to our overall performance, ability to lead his or her business unit or function, and work as part of a team, all of which reflect our core values;

• compensation parity among our NEOs;

• with respect to NEOs other than our CEO and Ms. Tucker, our Executive Chair, the recommendations of the CEO; and

• the compensation practices of our compensation peer group and the positioning of each NEO’s compensation in a ranking of peer company compensation levels.

These factors provide the framework for compensation decision-making and final decisions regarding the compensation opportunities for each NEO.

Role of Management

The Compensation Committee believes each of our CEO, CFO and CLAO has valuable insight into the contributions of our NEOs and solicits advice and input from each with respect to performance objectives under our annual bonus plan. In addition, our CFO provides input with respect to the establishment of metrics and targets for our annual incentive plan and our performance-based equity awards. Our CEO also provides input with respect to adjustments to annual base salaries, annual cash bonus opportunities, long-term equity incentive compensation opportunities, program structures, and other compensation-related matters for our NEOs (other than with respect to compensation for our CEO and our Executive Chair). The Compensation Committee reviews and discusses this advice and input, along with the information, analysis and other advice it receives from its external compensation consultant, with our CEO (other than with respect to compensation for our CEO and our Executive Chair) and uses them as factors in determining and approving the compensation for our NEOs. None of our officers is involved in decisions regarding their own compensation.

Role of Compensation Consultant

The Compensation Committee engages an external compensation consultant to assist it by providing information, analysis, and other advice relating to our executive compensation program and the decisions

resulting from its annual executive compensation review. For 2022, the Compensation Committee retained Compensia to serve as its compensation advisor. This compensation consultant serves at the discretion of the Compensation Committee.

During 2022, Compensia regularly attended the meetings of the Compensation Committee and provided the following services:

• consulting with the Compensation Committee Chair and other members between Compensation Committee meetings;

• providing competitive market data based in part on the compensation peer group for our NEO positions and evaluating how the compensation we pay our NEOs compares both to our performance and to how the companies in our compensation peer group compensate their executives;

• assessing executive compensation trends within our industry, and updating on corporate governance and regulatory issues and developments;

• providing competitive market data based on the compensation peer group for our Board and evaluating how the compensation we pay the non-employee members of our Board compares to how the companies in our compensation peer group compensate their boards of directors; and

• reviewing market equity compensation practices, including “burn rate” and “overhang.”

In 2022, Compensia did not provide any services to us other than the consulting services provided to the Compensation Committee. The Compensation Committee regularly reviews the objectivity and independence of the advice provided by its compensation consultant on executive compensation. The Compensation Committee has considered the six specific independence factors adopted by the SEC and reflected in the listing standards of Nasdaq and determined that the work of Compensia did not raise any conflicts of interest.

Competitive Positioning

To compare our executive compensation against the competitive market, the Compensation Committee reviews and considers the compensation levels and practices of a group of comparable technology companies. The companies in this compensation peer group were selected on the basis of their similarity to us in size and industry focus. For 2022 pay decisions, the Compensation Committee used compensation data derived from the compensation peer group as updated in August 2021. The companies in this compensation peer group were selected on the basis of their similarity to us, based on these criteria:

• similar revenue size - ~0.5x to ~2.0x our last four fiscal quarter revenue of approximately $368 million (for Q4 of 2021);

• similar market capitalization - ~0.3x to ~3.0x our market capitalization of approximately $6.2 billion (around the time of the peer group review in August 2021);

• similar revenue growth and market-capitalization to revenue ratio;

• industry - application software, internet services and infrastructure, and systems software;

• executive positions similar in breadth, complexity, and/or scope of responsibility; and

• competitors for executive talent.

After consultation with Compensia, the Compensation Committee approved the following compensation peer group for 2022 compensation decisions:

Alteryx	Everbridge	Qualys
Anaplan	LivePerson	Rapid7
Appfolio	nCino	Smartsheet
Appian	New Relic	Varonis Systems
Avalara	Pager Duty	Workiva
Bill.com Holdings	Paylocity Holding
Coupa Software	Q2 Holdings

TABLE OF CONTENTS

To analyze the executive compensation practices of the companies in our compensation peer group, Compensia gathered data from public filings. This information is supplemented with survey data from the Radford Global Compensation Survey database of companies that are similar to us in revenue, market capitalization and industry for purposes of providing additional perspective in the case of executive positions where the compensation peer group offered a limited number of relevant data points. This market data was then used as a reference point for the Compensation Committee to assess our current executive compensation levels in its deliberations on compensation forms and amounts.

The Compensation Committee reviews our compensation peer group at least annually and adjusts its composition, taking into account changes in both our business and the businesses of the companies in the peer group.

Stockholder Advisory Votes on Named Executive Officer Compensation

Our stockholders have an opportunity to cast an advisory vote to approve (i) our NEOs’ compensation and (ii) the frequency of the vote to approve the NEOs’ compensation (“Say-on-Frequency”). We hold the advisory vote on our NEOs' compensation annually and the Say-on-Frequency vote every six years. Our next Say-on-Frequency vote will be held in 2025.

At the 2022 annual meeting, over 94% of the advisory votes cast on our NEOs’ 2021 compensation voted to approve and there was no vote on the frequency of this advisory vote. We believe that the results of this vote affirm our stockholders’ support of our approach to executive compensation, and therefore we have not made any significant changes to our executive compensation program. We will consider the results from this year’s and future years’ stockholder advisory votes on NEO compensation when making decisions about our executive compensation program.

Anchor Individual Compensation Elements

In 2022, the primary elements of our executive compensation program consisted of base salary, an annual cash bonus opportunity, and long-term equity incentive compensation in the form of time-based RSU and option awards.

Base Salary

Base salary represents the fixed portion of the compensation of our NEOs and is an important element of compensation intended to attract and retain highly talented individuals. Generally, we establish the initial base salaries of our NEOs through arm’s-length negotiation at the time we hire the individual NEO, taking into account competitive market data, his or her position, qualifications, experience, prior salary level, and the base salaries of our other NEOs. Thereafter, the Compensation Committee reviews the base salaries of our NEOs annually and makes adjustments to base salaries as it determines to be necessary or appropriate.

In March 2022, effective as of April 1, 2022, the Compensation Committee reviewed and approved an increase to the base salary of each of our NEOs other than Mr. Woodhams. In determining these adjustments, the Compensation Committee considered a competitive market data analysis provided by Compensia, and the recommendations of our CEO (other than with respect to base salaries for our CEO and our Executive Chair).

In June 2022, effective as of June 1, 2022, the Compensation Committee reviewed and approved an increase to the base salary of Mr. Woodhams. In determining this adjustment, the Compensation Committee considered a competitive market data analysis provided by Compensia, and the recommendations of our CEO.

The annual base salaries for our NEOs that were in effect as of the end of 2021 and 2022, respectively, are set forth below:

NEO	2021 Base Salary	2022 Base Salary	Percentage Increase
Therese Tucker	$328,000	$344,000	4.9%
Marc Huffman	$475,000	$500,000	5.3%
Mark Partin	$390,000	$410,000	5.1%
Karole Morgan-Prager	$370,000	$390,000	5.4%
Mark Woodhams	$380,000	$400,000	5.3%

Target Annual Cash Bonus Opportunities

Each NEO participated in the 2021 Bonus Plan, which was designed to motivate our NEOs to drive “top line” growth (using a revenue goal) as well as “bottom line” profitability (using a non-GAAP net income goal). Additionally, the Compensation Committee has the discretion to determine achievement of a discretionary component (weighted 20%), as described below.

Each NEO was assigned a target annual cash bonus opportunity for 2022, representing a percentage of his or her annual base salary.

In March 2022, the Compensation Committee reviewed the target annual cash bonus opportunities of our NEOs for 2022, taking into consideration a competitive market analysis prepared by Compensia, and the recommendations of our CEO (for all NEOs other than our CEO and our Executive Chair).

Following this review, the Compensation Committee determined to increase the target annual cash bonus opportunity percentage for Mr. Partin from 60% to 70% in consideration of the positioning of Mr. Partin’s cash compensation in relation to the market analysis. The Compensation Committee did not make any changes to the target annual cash bonus opportunity percentages of our other NEOs.

The 2022 target annual cash bonus opportunities of the NEOs were as follows:

NEO	2022 Target Annual Cash Bonus Opportunity (as a percentage of base salary)	2022 Target Annual Cash Bonus Opportunity
Therese Tucker	75%	$258,000
Marc Huffman	100%	$500,000
Mark Partin	70%	$287,000
Karole Morgan-Prager	50%	$195,000
Mark Woodhams	100%	$400,000

Each NEO participant in the 2022 Bonus Plan was eligible to earn a payment with respect to the financial portion applicable to his or her target annual cash bonus opportunity depending on our actual performance for the year as measured against the financial performance components, and additional amounts under the discretionary component of the 2022 Bonus Plan. As described in the section “2022 Bonus Plan Performance Matrix” below, overperformance against the bonus plan components could result in payments in excess of each NEO's target opportunity, while underperformance would result in payments below that target opportunity, or in no payment being earned with respect to one or more components.

2022 Bonus Plan Performance Matrix

In March 2022, the Compensation Committee, with input from management, approved revenue and non-GAAP net income as the performance measures for the financial component under the 2022 Bonus Plan. The Compensation Committee selected these performance measures because it believed that they were appropriate drivers for our business as they provided a balance between growing our business, and managing our expenses, which enhance stockholder value over the short term.

The 2022 Bonus Plan was to be funded based on (i) the extent of our achievement against the target level of each of the financial metrics and (ii) the discretion exercised by the Compensation Committee under the discretionary component, all as set forth below:

2022 Bonus Plan Performance Measure	Category	Target Level	Weighting (%)
Revenue	Financial Component	$536.0 million	50%
Net Income	Financial Component	$12.4 million	30%
Discretionary	Discretionary Component	$—	20%

TABLE OF CONTENTS

The revenue measure funded with respect to that performance measure as follows:

Percentage Achievement of 2022 Revenue target*			Payment Percentage of Revenue Measure*
97.5%			60%
100.0%			100%
102.0%			150%
104.0%			200%

The non-GAAP net income measure funded with respect to that performance measure as follows:

Percentage Achievement of 2022 Net Income target*			Payment Percentage of Net Income Measure*
85.5%			50%
100.0%			100%
132.3%			125%

If Revenue and Net Income achievement during 2022 is between the percentage levels identified above, then the payment percentage with respect to the applicable performance metric is calculated based on a linear interpolation between those levels (rounded to one decimal).

For purposes of the 2022 Bonus Plan, the financial performance measures had the following meanings:

	Performance Measure	Meaning
	Revenue	“Revenue” is defined as the Company’s total subscription, support, and
professional services revenue recognized under Generally Accepted Accounting Principles (“GAAP”) during the Performance Period, excluding revenues from acquisitions completed in 2022 with the exception of FourQ.
	Net Income	“Net Income” is defined as the Company’s non-GAAP net income (loss) for the
Performance Period as defined in the Company’s Earnings Release filed on February 10, 2022 on Form 8-K. The Net Income performance measure shall exclude expenses related to acquisitions completed during the Company’s 2022 fiscal year with
the exception of FourQ. Please see Appendix A to this proxy statement for a reconciliation of GAAP and non-GAAP net income (loss).

The discretionary component was included to provide the Compensation Committee with flexibility to incent achievement of business goals and objectives that may evolve after the beginning of the year. The Compensation Committee believed that retaining discretion to fund a portion of the 2022 Bonus Plan irrespective of achievement of the financial component was important to reward our NEOs for achievements not directly captured by these financial performance measures.

2022 Bonus Plan Decisions

In February 2023, the Compensation Committee reviewed our overall performance for 2022, including performance against the performance measures established under the 2022 Bonus Plan. Using the 2022 Bonus Plan performance measures, the discretion it reserved under the discretionary component, the target performance, actual performance and relative weighting were as follows:

Performance Measure	Target Performance Level	Actual Performance Level	Weighted Payment Percentage
Revenue	$536.0 million	$522.9 million	61%
Net Income	$12.4 million	$46.3 million	125%
Discretionary	$—	$—	70%

The Compensation Committee determined the payment percentage under the discretionary component after assessing the contributions of our NEOs in 2022 toward our execution on key initiatives that we expect to have long-term benefits on our business and to drive stockholder value over the long-term, including strong

achievements in bookings, execution on expense control, opening the India Development Center, product roadmap and integration, our BeyondTheBlack user conference and increasing the number of our premier customers.

Based on this level of achievement, the 2022 Bonus Plan funded at 82% of the target amount for each of our NEOs.

The target annual cash bonus opportunities and the actual cash bonus payments made to the NEOs for 2022 are as follows:

NEO	Target Annual Cash Bonus Opportunity	Total Actual 2022 Cash Bonus Payment
Therese Tucker	$258,000	$ 211,570
Marc Huffman	$500,000	$410,020
Mark Partin	$287,000	$235,351
Karole Morgan-Prager	$195,000	$159,908
Mark Woodhams	$400,000	$328,016

Long-Term Equity Compensation

The Compensation Committee believes long-term equity compensation is an effective means for focusing our NEOs on driving increased stockholder value over a multi-year period, providing a meaningful reward for appreciation in our stock price and long-term value creation, and motivating them to remain employed with us.

Annual Long-Term Equity Awards

In March 2022, the Compensation Committee reviewed its past practice of granting a mix of time-based restricted stock unit awards that are settled in shares of our common stock (RSUs) and stock options to our executive officers in light of an analysis of long-term equity compensation granted by its peers that was created by its compensation consultant, Compensia. Based on this analysis, the Compensation Committee determined that awards of long-term equity compensation to our executive officers for 2022 would be made in a mix of RSUs and performance-based restricted stock units that are settled in shares of our common stock (PSUs).

In March and April 2022, the Compensation Committee determined the sizes of the 2022 equity awards for our NEOs and granted equity awards to all our NEOs other than Ms. Tucker in the form of 50% time-based RSU awards and 50% performance-based PSUs. In consideration of Ms. Tucker’s role as Executive Chair in 2022, we granted her equity awards for 2022 in the form of time-based RSU awards only. The Compensation Committee believed that providing an equal mix of time-based RSUs and performance-based PSUs for NEOs other than Ms. Tucker was important to remain competitive with our compensation peer companies, many of whom use a similar mix and to provide a performance-based element to more directly align such NEOs’ compensation with stockholder value creation. RSU awards provide retention incentives for our NEOs and reward them for long-term stock price appreciation while at the same time providing some value even if the market price of our common stock declines. PSU awards provide these same benefits, along incentives for our NEOs to achieve performance milestones intended to grow our business and drive value for our stockholders.

As with their other elements of compensation, the Compensation Committee determined the amount of long-term incentive compensation for our NEOs for 2022 as part of its annual compensation review and after taking into consideration a competitive market analysis, the recommendations of our CEO (except with respect to long-term equity compensation for our CEO and our Executive Chair), each NEO’s skills, experience, and role within the organization, the outstanding equity holdings of each NEO (including the vested and unvested status of such equity holdings), the proportion of our total shares outstanding used for annual employee long-term equity compensation awards (our “burn rate”) in relation to the companies in our compensation peer group, the potential voting power dilution to our stockholders (our “overhang”) in relation to the companies in our compensation peer group, and the other factors described above.

(2) The number of shares was determined by dividing 50% of the targeted grant value by the 30 trading day average price ended on March 15, 2022 and rounding up to the nearest 10 shares.

The RSU award listed in the table above for Ms. Tucker vests as to 50% of the shares underlying the award on each of February 20, 2023 and February 20, 2024, subject to her continued service with us through the applicable date.

Each of the RSU awards listed in the table above for our other NEOs vests as to 25% of the shares underlying the award on February 20, 2023 and as to 1/16 th of the shares underlying the award each quarter thereafter, subject to the NEO’s continued service with us through the applicable date.

Each of the PSU awards listed in the table above vests as to one-third of the shares underlying the award on each of February 20, 2023, 2024 and 2025, in each case subject to the NEO’s continued service with us through the applicable date, and in each case subject to our satisfaction of applicable performance-based conditions for the calendar year preceding the vesting date. These performance goals will be determined on an annual basis. The performance goals for vesting of the PSU awards which were eligible to vest on February 20, 2023 were determined at the time of grant, relate to our performance in 2022, and are detailed in the section “2022 Performance-Based Restricted Stock Unit Performance Matrix” below.

Ms. Tucker’s annual equity grant was made entirely in time-based RSUs, and not performance-based PSUs, taking into account corporate governance considerations in light of Ms. Tucker’s role as Executive Chair of our Board, with responsibility for oversight of the Company.

All of these awards are subject to additional vesting acceleration as described in the “Potential Payments Upon Termination or Change of Control” section below.

2022 Performance-Based Restricted Stock Unit Performance Matrix

In March 2022, the Compensation Committee, with input from management, approved revenue, annualized recurring revenue (ARR), and non-GAAP net income as the performance measures for 2022 as the performance metrics for the portion of the 2022 performance-based RSUs scheduled to vest on February 20, 2023. The Compensation Committee selected these performance measures because it believed that they were appropriate drivers for our business as they provided a balance between growing our business, and managing our expenses, which enhance stockholder value over the short term.

The portion of the 2022 performance-based RSUs scheduled to vest on February 20, 2023 was to be available for vesting based on the extent of our achievement against the target level of each of the financial metrics, as set forth below:

2022 Bonus Plan Performance Measure	Target Level	Weighting
Revenue	$536 million	40%
ARR	$569 million	30%
Non-GAAP net income	$12.4 million	30%

TABLE OF CONTENTS

The portion of the 2022 performance-based RSUs scheduled to vest on February 20, 2023 that is subject to the revenue metric will be available for vesting based on attainment of that performance measure as follows:

Percentage Achievement of 2022 Revenue target*			Percentage of Subject Award Available for Vesting*
97.57%			50%
100.0%			100%
102.0%			125%
104.0% and above			150%

The portion of the 2022 performance-based RSUs scheduled to vest on February 20, 2023 that is subject to the ARR metric will be available for vesting based on attainment of that performance measure as follows:

Percentage Achievement of 2022 ARR target*			Percentage of Subject Award Available for Vesting*
93.67%			50%
100.0%			100%
104.9%			125%
110.0% and above			150%

The portion of the 2022 performance-based RSUs scheduled to vest on February 20, 2023 that is subject to the non-GAAP net income metric will be available for vesting based on attainment of that performance measure as follows:

Percentage Achievement of 2022 non-GAAP net income target*			Percentage of Subject Award Available for Vesting*
85.5%			50%
100.0%			100%
164.5%			125%
229.0%			150%

If Revenue and non-GAAP net income achievement during 2022 is between the percentage levels identified above, then the payment percentage with respect to the applicable performance metric is calculated based on a linear interpolation between those levels (rounded to the nearest hundred thousand dollars).

For purposes of the portion of the 2022 performance-based RSUs scheduled to vest on February 20, 2023, the financial performance measures had the following meanings:

	Performance Measure	Meaning
	Revenue	“Revenue” is defined as the Company’s total subscription, support, and
professional services revenue recognized under Generally Accepted Accounting Principles (“GAAP”) during the Performance Period, excluding revenues from acquisitions completed in 2022 with the exception of FourQ.
	ARR	“ARR” is defined as the Company’s contracted annualized recurring subscription
and support revenue. ARR shall exclude the impact of any acquisitions completed during the company’s 2022 fiscal year with the exception of FourQ.
	Net Income	The Company’s “non-GAAP net income (loss)” for the Company’s 2022 fiscal year as
determined in accordance with how such term is defined in the Company’s annual report filed on its Form 10-K for the Company’s 2022 fiscal year, excluding expenses related to acquisitions completed during 2022 with the exception of FourQ.
Please see Appendix A to this proxy statement for a reconciliation of GAAP and non-GAAP net income (loss).

2022 Performance-Based Restricted Stock Unit Performance Decisions

In February 2023, the Compensation Committee reviewed our overall performance for 2022, including performance against the performance measures established under the 2022 performance-based PSU awards for

TABLE OF CONTENTS

shares eligible to vest on February 20, 2023. Considering the performance measures established for those awards, the target performance, actual performance, and percent available for vesting before relative weighting were as follows:

Performance Measure	Target Performance Level	Actual Performance Level	Pre-Weighting Vesting Percentage
Revenue	$536.0 million	$522.9 million	0%
ARR	$569.0 million	$533.4 million	50.6%
Non-GAAP net income	$12.4 million	$46.2 million	150%

For context, we believe the target for non-GAAP net income was the appropriate goal for that metric despite it being lower than the Company’s fiscal 2021 non-GAAP net income. When the target was set in early 2022, we believed that integration costs and dilution associated with our FourQ acquisition, increased hosting costs associated with our continued migration to the public cloud, and additional investments to accelerate our go-to-market strategy made the achievement of $12.4 million in non-GAAP net income a rigorous goal. Our overachievement in 2022 with respect to non-GAAP net income was the result of focused work and leadership related to our cost structure as we addressed the challenging macroeconomic environment that developed during the year. Based on this level of achievement, the Compensation Committee determined that, with respect to the shares eligible to vest on February 20, 2023 under the 2022 performance-based PSU awards, 60.2% of the target amount for each of our NEOs were eligible to vest.

The numbers of shares available for vesting on February 20, 2023 under the 2022 performance-based PSUs for each of our NEOs are as follows:

Named Executive Officer	Target 2022 PSUs Eligible to Vest on 2/20/2023 (Number of Shares)	Total 2022 PSUs Earned and Vesting on 2/20/2023 (Number of Shares)
Therese Tucker	—	—
Marc Huffman	21,743	13,082
Mark Partin	10,873	6,541
Karole Morgan-Prager	5,653	3,401
Mark Woodhams	6,523	3,924

Retention Long-Term Equity Awards

In the fall and winter of 2022, the Compensation Committee considered an additional grant of long-term equity awards to our executive officers in light of an analysis of the retentive value of long-term equity compensation granted by the Company’s peers that was created by its compensation consultant, Compensia. Based on this analysis and concerns over the retentive value the then current outstanding long-term equity awards for our executive officers, the Compensation Committee determined to grant additional awards of performance-based PSUs for Mr. Huffman and of time-based RSUs for our other executive officers. Ms. Tucker’s award was granted in connection with her assumption of an operating role at the Company as she transitioned away from service as Executive Chair of the Board while continuing to serve on our Board.

In December 2022, the Compensation Committee approved retention equity awards to our NEOs, the material terms of which are described below:

Named Executive Officer	Retention PSUs or RSUs (Number of Shares) (2)	Equity Awards (Targeted Grant Value) (1)
Therese Tucker	23,680	$ 1,500,000
Marc Huffman	189,400	$12,000,000
Mark Partin	55,240	$ 3,500,000
Karole Morgan-Prager	39,460	$ 2,500,000
Mark Woodhams	28,410	$ 1,800,000

(1) The number of shares was determined by dividing the targeted grant value by the 30 trading day average price ended on December 15, 2022 and rounding to the nearest 10 shares.

(2) The award for Ms. Tucker was made effective as of January 1, 2023. All other awards listed here were made effective as of December 30, 2022.

TABLE OF CONTENTS

The retention RSU award for Ms. Tucker listed in the table above vests as to 1/8 th of the shares underlying the award on a quarterly basis, beginning on February 20, 2023, in each case subject to Ms. Tucker’s continued service with us through the applicable date.

Each of the retention RSU awards for our NEOs other than Ms. Tucker and Mr. Huffman listed in the table above vests as to 2/3rd of the shares underlying the award on November 20, 2024, and as to 1/3rd of the shares underlying the award on November 20, 2025, in each case subject to the NEO’s continued service with us through the applicable date.

The retention performance-based PSU award for Mr. Huffman listed in the table above was eligible to vest as to up to 200% of the shares available for vesting under the award on February 20, 2026, or, if not then vested, on February 20, 2027, in each case subject to Mr. Huffman’s continued service with us through the applicable date, and subject to our satisfaction of applicable performance-based conditions, as described in the following section. Because Mr. Huffman’s employment terminated prior to February 20, 2026, he forfeited all of this award.

Retention Performance-Based Restricted Stock Unit Performance Matrix

In December 2022, the Compensation Committee, with input from management, approved performance metrics for the retention performance-based PSU award granted to Mr. Huffman, relating to the Company’s revenue growth, operating margin, and relative total shareholder return (relative TSR). The Compensation Committee selected these performance measures because it believed that they were aligned with our long-range plan and provided appropriate drivers for our business as they provide a balance between growing our business and managing our expenses, which enhance stockholder value, and directly address our stock performance relative to our peers.

The percentage of retention performance-based RSUs for Mr. Huffman that would have been eligible to vest on February 20, 2026 will equal the product of (i) the revenue growth plus operating margin multiplier for 2025 determined under the first table below, multiplied by (ii) the relative TSR multiplier determined under the second table below.

If the revenue growth plus operating margin multiplier for 2025 was less than 100%, then an additional percentage of the retention performance-based RSUs for Mr. Huffman would become eligible to vest under this award on February 20, 2027, which will equal the excess, if any, of (A) the revenue growth plus operating margin multiplier for 2026 (or if lower, 100%) over (B) the revenue growth plus operating margin multiplier for 2025, in each case determined under the first table below.

For purposes of these awards, the revenue growth plus operating margin multiplier for a given year will be determined based on the sum of the Company’s revenue growth for that year, and the Company’s operating margin for that year, as provided in the following table:

Fiscal year revenue growth plus fiscal year operating margin			Revenue growth plus operating margin multiplier*
40%			160%
39%			125%
38%			100%
36%			75%
32%			50%
Below 32% (or in any case, if revenue growth is below 20%)			0%

For performance falling between two adjacent “bands” in the first column, the multiplier will be calculated by linear interpolation between (a) the two adjacent bands represented as percentages of growth plus margin and (b) the two achievement percentages set forth in the multiplier column that correspond to the two adjacent bands of percentages of growth plus margin.

TABLE OF CONTENTS

For purposes of these awards, the relative TSR multiplier will be determined based on the Company’s total shareholder return for the period beginning on December 31, 2022 (measured based on the average closing price for the 20 trading days ending on that date) and ending on December 31, 2025 (measured based on the average closing price for the 20 trading days ending on that date) relative to the corresponding TSRs of the members of the S&P Software and Services Select Industry Index, expressed as a percentile, as provided in the following table:

Relative TSR percentile			Revenue TSR multiplier*
75 th or higher			125%
50 th			100%
25 th or below			75%

For performance falling between two adjacent “bands” in the first column, the multiplier will be calculated by linear interpolation between (a) the two adjacent bands represented as percentiles of relative TSR and (b) the two achievement percentages set forth in the multiplier column that correspond to the two adjacent bands of percentages of growth plus margin.

For purposes of the retention performance-based PSU awards granted to Mr. Huffman, the financial performance measures had the following meanings:

	Performance Measure	Meaning
	Revenue growth	The sum of Company’s subscription revenue plus services revenue for the given
fiscal year, divided by the sum of the Company’s subscription revenue plus services revenue for the Company’s immediately prior fiscal year; all as determined under GAAP, but excluding revenue related to acquisitions during the
performance period to the extent that any such acquisition is of an entity with greater than $50M in trailing twelve-month revenue at the time of the acquisition.
	Non-GAAP operating margin	The Company’s non-GAAP income from operations divided by its total revenues, as
determined under GAAP.
	Non-GAAP income from operations	The Company's non-GAAP income from operations means the Company’s GAAP income
(loss) from operations, adjusted for: amortization of intangible assets, stock-based compensation, the change in the fair value of contingent consideration, transaction-related costs, legal settlement gains and costs, restructuring
charges, impairment charges related to goodwill, impairment charges related to tangible and intangible assets, and the costs of natural disasters. To the extent the Company completes an acquisition of an entity with greater than
$50 million in trailing twelve-month revenue, the revenue and transaction costs associated with that transaction shall be removed from the calculation of Revenue Growth and Non-GAAP income from operations for the purposes of calculated
achievement.

Employee Benefits

Our NEOs are eligible to participate in our employee benefit programs on the same basis as our other full-time, salaried employees. We sponsor a Section 401(k) profit-sharing plan, which is intended to qualify for favorable tax treatment under Section 401(a) of the Code. Our eligible U.S. employees, including the NEOs, are entitled to participate on the first day of the month following the date of hire. The Section 401(k) plan includes a salary deferral arrangement under which participants may elect to defer up to 100% of their current eligible compensation up to the statutorily prescribed limit. All participants’ interests in their deferrals are 100% vested when contributed. The Section 401(k) plan permits us to make matching contributions and profit-sharing contributions to eligible participants. In 2022, we paid discretionary matching contributions that are fully vested.

In addition, our NEOs are eligible to participate in our employee benefit programs on the same basis as all of our employees. These benefits include medical, dental and vision benefits, disability insurance, basic life insurance coverage, health savings accounts, and accidental death and dismemberment insurance. All NEOs, except for Ms. Tucker, are also eligible to participate in our employee stock purchase plan (ESPP).

TABLE OF CONTENTS

We design our employee benefits programs to be affordable and competitive in relation to the market, as well as compliant with applicable laws and practices. We adjust our employee benefits programs as needed based upon regular monitoring of applicable laws and practices and the competitive market.

Perquisites, Special Bonuses and Other Personal Benefits

Currently, we do not view perquisites, special bonuses, or other personal benefits as a significant component of our executive compensation program. Accordingly, we do not provide perquisites, special bonuses, or other personal benefits to our NEOs, except in situations where we believe it is appropriate to assist an individual in the performance of his or her duties, to make our NEOs more efficient and effective, and for recruitment and retention purposes.

Employment Arrangements

We have entered into written employment offer letters with each of our NEOs, other than Mr. Ryan and Ms. Tucker, and an employment agreement with each of Mr. Ryan and Ms. Tucker. Each of these employment arrangements was approved on our behalf by the Compensation Committee or, in certain instances, by our Board. Each of these employment arrangements provides for “at will” employment and set forth the compensation arrangements for the NEO, including base salary and an annual cash bonus opportunity.

On March 5, 2023, in connection with Ms. Tucker’s transition to become Co-CEO, we entered into an employment agreement with Ms. Tucker, which supersedes her prior employment agreement. We entered into an employment agreement with Mr. Ryan at the same time on substantially the same terms. In connection with this transition, the Compensation Committee approved an increase to Ms. Tucker’s base salary in connection with her transition from Executive Chair to co-CEO. In determining this adjustment, the Compensation Committee considered a competitive market data analysis provided by Compensia.

In filling each of our executive positions, our Board or the Compensation Committee, as applicable, recognized that it would need to develop competitive compensation packages to attract qualified candidates in a dynamic labor market. At the same time, our Board and the Compensation Committee were sensitive to the need to integrate new executive officers into the executive compensation structure that we were seeking to develop, balancing both competitive and internal equity considerations.

For information on the specific terms and conditions of the employment arrangements of the NEOs, see the discussion of “Executive Employment Arrangements” below.

Post-Employment Compensation

We entered into written participation agreements under our Change of Control and Severance Policy, or the Policy, with each of our NEOs (other than Ms. Tucker) and a written employment agreement with Ms. Tucker, providing for change of control and severance payments and benefits.

On March 5, 2023, in connection with Ms. Tucker’s transition to become Co-CEO, we entered into an employment agreement providing for post-employment compensation with Ms. Tucker, which supersedes her prior employment agreement.

We believe that having in place reasonable and competitive post-employment compensation arrangements are essential to attracting and retaining highly qualified executive officers. Our post-employment compensation arrangements are designed to provide reasonable compensation to executive officers who leave our Company under certain circumstances to facilitate their transition to new employment. Further, we seek to mitigate any potential employer liability and avoid future disputes or litigation by requiring a departing executive officer to sign a separation and release agreement acceptable to us as a condition to receiving post-employment compensation payments or benefits.

We do not consider specific amounts payable under these post-employment compensation arrangements when establishing annual compensation. We do believe, however, that these arrangements are necessary to offer compensation packages that are competitive.

We believe that these arrangements are designed to align the interests of management and stockholders when considering the long-term future for the Company. The primary purpose of these arrangements is to keep

TABLE OF CONTENTS

our most senior executive officers focused on pursuing all corporate transaction activity that is in the best interests of stockholders regardless of whether those transactions may result in their own job loss. Reasonable post-acquisition payments and benefits should serve the interests of both the executive and our investors.

All payments and benefits in the event of a change of control of the Company are payable only if there is a subsequent loss of employment by an executive officer (a so-called “double-trigger” arrangement). In the case of the acceleration of vesting of outstanding equity awards, we use this double-trigger arrangement to protect against the loss of retention power following a change of control and to avoid windfalls, both of which could occur if vesting accelerated automatically as a result of the transaction.

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

For information on the change of control and severance agreements for the NEOs, as well as an estimate of the potential payments and benefits payable under these agreements as of the end of 2022, see “Executive Employment Arrangements” and “Potential Payments Upon Termination or Change of Control” below.

Anchor Other Compensation Policies and Practices

Policy Prohibiting Hedging or Pledging of Our Equity Securities

Our Insider Trading Compliance Policy prohibits all our employees, including our NEOs, and the members of our Board from engaging in derivative securities transactions, including hedging, with respect to our common stock and from pledging our securities as collateral or holding our securities in a margin account.

Executive Stock Ownership Guidelines

In February 2020, the Compensation Committee and the Nominating and Corporate Governance Committee recommended, and our Board approved, stock ownership guidelines for our executive officers. Under these guidelines, each executive officer is expected to attain minimum levels of stock ownership equal to 1x (or 5x, in the case of the CEO and Executive Chair, if applicable) the executive officer’s annual base salary. For purposes of this requirement, shares counted toward these guidelines include any shares owned outright and in-the-money value of vested but unexercised stock options. The value for purposes of satisfying this requirement is the 90-day trailing average of the closing price of our common stock as of the last trading day of the fiscal year prior to the compliance date. Executive officers have until the later of February 2025 or, if applicable, the fifth anniversary of the date they become an executive officer or are appointed to their position to comply with these guidelines. If an executive officer does not achieve the minimum level of ownership by the executive officer’s compliance date, then 50% of the after-tax value of the executive officer’s exercised options or vested RSUs will be retained until the minimum level of ownership for the executive officer is met. As of December 31, 2022, all of our executive officers had exceeded the current guidelines.

Anchor Tax and Accounting Considerations

Deductibility of Executive Compensation

Section 162(m) of the Code generally limits the amount we may deduct from our federal income taxes for compensation paid to our CEO and certain other current and former executive officers that are “covered employees” within the meaning of Section 162(m) of the Code to $1 million per individual per year, subject to certain exceptions. The regulations promulgated under Section 162(m) of the Code contain a transition rule that applies to companies, such as ours, that become subject to Section 162(m) of the Code by reason of becoming publicly held. Pursuant to this rule, certain compensation granted during a transition period (which ended on the 2020 annual meeting for us) currently is not counted toward the deduction limitations of Section 162(m) of the Code if the compensation is paid under a compensation arrangement that was in existence before the effective date of the initial public offering and certain other requirements are met. While certain of our equity awards may be eligible to be excluded from our deductibility limitation of Section 162(m) of the Code pursuant to this transition rule, the Compensation Committee has not adopted a policy that all equity or other compensation must be deductible.

In approving the amount and form of compensation for our NEOs in the future, the Compensation Committee generally considers all elements of the cost to us of providing such compensation, including the

TABLE OF CONTENTS

potential impact of Section 162(m) of the Code, as well as our need to maintain flexibility in compensating executive officers in a manner designed to promote our goals. The Compensation Committee may, in its judgment, authorize compensation payments that will or may not be deductible when it believes that such payments are appropriate to attract, retain or motivate executive talent.

Accounting for Stock-Based Compensation

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

Risk Considerations

The Compensation Committee, in cooperation with management, reviewed our 2022 compensation programs. Our Compensation Committee believes that the mix and design of the elements of such programs do not encourage our employees to assume excessive risks and accordingly are not reasonably likely to have a material adverse effect on our Company. We have designed our compensation programs to be balanced so that our employees are focused on both short and long-term financial and operational performance. In particular, the weighting towards long-term incentive compensation discourages short-term risk taking. Goals are appropriately set with targets that encourage growth in the business, while doing so in a manner that encourages profitability.

Anchor Executive Employment Arrangements

Therese Tucker. On August 24, 2016, we entered into an employment agreement with Ms. Tucker, which remained in effect through March 5, 2023. The employment agreement had an initial term of three years from January 1, 2016 and was expected to automatically renew on each year thereafter, unless either party provided the other with at least 30 days written notice. The employment agreement automatically renewed for a one-year term on January 1, 2022. In the event of a “change in control” (as defined in Ms. Tucker’s agreement), the term would extend for an additional two years from the date of such change in control.

The employment agreement provided Ms. Tucker with an initial annual base salary of $350,000 and an on-target bonus opportunity equal to 100% of her base salary, based upon achievement of performance objectives to be determined by our Compensation Committee. Effective January 2021, in connection with her transition to Executive Chair, Ms. Tucker’s annual base salary was reduced to $328,000 and her on-target bonus opportunity was reduced to 75% of her base salary. Effective April 1, 2022, Ms. Tucker’s annual base salary was increased to $344,000.

Ms. Tucker’s employment agreement also provided that if her employment was terminated by us without “cause” (excluding by death or disability), we decided to not renew Ms. Tucker’s agreement, or Ms. Tucker resigned for “good reason” (as such terms were defined in Ms. Tucker’s agreement), Ms. Tucker would receive (i) a lump sum payment equal to 18 months of Ms. Tucker’s base salary then in effect; (ii) a lump sum payment equal to the premium costs for Ms. Tucker and her eligible dependents to continue health insurance coverage under COBRA for 18 months; (iii) a lump sum amount equal to the prorated portion of Ms. Tucker’s annual bonus for the year of termination that would have been paid to Ms. Tucker had Ms. Tucker been employed by us for the entire fiscal year of termination, based on actual performance for the year (and assuming any individual performance goals would have been met at target levels); and (iv) a lump sum amount equal to the earned but unpaid bonus for the prior fiscal year, if any.

Ms. Tucker’s employment agreement also provided that if her employment was terminated by us without “cause” (excluding by death or disability), we decided to not renew Ms. Tucker’s agreement, or Ms. Tucker resigned for “good reason” and such termination occurs in connection with, or within three months before or 24 months after a “change of control” (as such term is expected to be defined in Ms. Tucker’s agreement), Ms. Tucker would receive (i) a lump sum payment equal to 12 months of Ms. Tucker’s base salary then in effect, or, if greater, as in effect immediately prior to the change of control; (ii) a lump sum payment equal to the

TABLE OF CONTENTS

premium costs for Ms. Tucker and her eligible dependents to continue health insurance coverage under COBRA for 12 months; (iii) a lump sum amount equal to the earned but unpaid bonus for the prior fiscal year, if any; and (iv) 100% of the shares subject to Ms. Tucker’s outstanding company equity awards would vest and, to the extent applicable, become exercisable.

Ms. Tucker’s employment agreement also provided that if her employment was terminated due to her death or disability, Ms. Tucker would receive (i) a lump sum amount equal to the earned but unpaid bonus for the prior fiscal year, if any and (ii) a lump sum amount equal to Ms. Tucker’s target bonus, pro-rated to reflect time served in the year of termination.

Any receipt of severance benefits by Ms. Tucker was be contingent upon her execution and non-revocation of a separation agreement and release of claims against us. In the event any of the payments provided for under Ms. Tucker’s employment agreement or otherwise payable to Ms. Tucker would constitute “parachute payments” within the meaning of Section 280G of the Internal Revenue Code of 1986, as amended, or the Code, could be subject to the related excise tax under Section 4999 of the Code, she would be entitled to receive either full payment of benefits or such lesser amount which would result in no portion of the benefits being subject to the excise tax, whichever resulted in the greater amount of after-tax benefits to her. Ms. Tucker’s employment agreement did not require us to provide any tax gross-up payments.

On March 5, 2023, in connection with Ms. Tucker’s transition to Co-CEO, effective as of March 6, 2023, we entered into an employment agreement with Ms. Tucker, which supersedes her prior employment agreement. Under this new employment agreement, as Co-CEO, Ms. Tucker will earn an annual base salary of $485,000 and have a target bonus of 100% of her salary.

TABLE OF CONTENTS

Anchor Stock Option Exercises and Stock Awards Vested During 2022

The following table sets forth the number of shares acquired and the value realized upon exercise of stock options during 2022 by each of our NEOs. The value realized on exercise of stock options is calculated based on the difference between the market price of our common stock upon exercise and the exercise price of the stock options.

Named Executive Officer	Option Awards — Number of Shares Acquired on Exercise (#) (1)	Value Realized on Exercise ($) (2)	Stock Awards — Number of Shares Acquired on Vesting (#)	Value Realized on Vesting ($)
Therese Tucker	—	—	40,797	2,853,824
Marc Huffman	—	—	73,263	5,455,262

(2) These estimates of cash severance payable to Ms. Tucker include: for termination upon a qualifying termination not in connection with a change of control, lump sum payments of 18 months of base salary and COBRA premium costs and prorated annual bonus for the year of termination; for termination due to death or disability, a prorated annual bonus for the year of termination; and for a qualifying termination in connection with a change of control, lump sum payments of 12 months of base salary and COBRA premium costs.

(3) For purposes of valuing accelerated vesting, the values indicated in the table are calculated, with respect to stock options, as the aggregate difference between $67.27, the closing price of a share of our common stock on December 31, 2022 (the last trading day of 2022), and the exercise price of the applicable option, multiplied by the number of unvested shares accelerated, with respect to time-based RSUs, $67.27 multiplied by the number of unvested RSUs accelerated, and, with repsect to performance-based PSUs, $67.27 multiplied by the number of PSUs for which performance conditions would be satisfied, or for which time-based vesting requirements would be accelerated.

(4) These estimates of cash severance payable to Mr. Huffman include: for termination upon a qualifying termination not in connection with a change of control, a lump sum payment of 12 months of base salary; and for a qualifying termination in connection with a change of control, a lump sum payment of 18 months of base salary.

(5) These estimates of continued health coverage reflect the present value of monthly COBRA premium payments for the applicable severance period.

(6) These estimates of cash severance payable to Mr. Partin, Ms. Morgan-Prager and Mr. Woodhams include: for termination upon a qualifying termination not in connection with a change of control, a lump sum payment of 6 months of base salary; and for a qualifying termination in connection with a change of control, a lump sum payment of 12 months of base salary.

Therese Tucker

We entered into an employment agreement with Ms. Tucker that provides for change of control and severance benefits under certain circumstances. See “Executive Employment Arrangements— Therese Tucker ” for further details.

Marc Huffman, Mark Partin, Karole Morgan-Prager, and Mark Woodhams

On May 12, 2022, our Compensation Committee conducted a periodic review of the severance and change in control protections provided to our NEOs other than Ms. Tucker under the Change of Control and Severance Policy. Based on such review, conducted with Compensia, the committee made certain modifications to such protections to align them with protections provided at compensation peer companies.

For Mr. Huffman, upon a qualifying termination in connection with a change of control, his cash severance would increase from six months of base salary to 18 months of base salary and his benefits continuation protection would increase from six months to 18 months. In addition, the change of control protection period for Mr. Huffman was extended to include a three-month period prior to the change of control. Upon a qualifying termination outside of the change of control period, his cash severance would increase from six months of his base salary to 12 months of his base salary and his benefits continuation protection period would increase from six months to 12 months. No changes were made to provide increased equity acceleration.

For the Company's NEOs other than Ms. Tucker and Mr. Huffman, upon a qualifying termination in connection with a change of control, the NEO's cash severance will increase from six months of base salary to 12 months of base salary, and benefits continuation protection will increase from six months to 12 months. No changes were made to benefits for a qualifying termination outside of the change of control period, and no changes were made to provide increased equity acceleration.

After the modifications to the Policy on May 12, 2022, the Policy provides for the following change of control and severance benefits for our NEOs and other key employees, other than Ms. Tucker:

If we terminate an executive officer’s employment other than for “cause,” death or “disability” or such participant resigns for “good reason” during the period from the period beginning on (or for Mr. Huffman, three months prior to) a “change of control” (as such terms are defined in the Policy) and ending 12 months following a change of control (the “change of control period”), such executive officer will be eligible to receive the following severance benefits (less applicable tax withholdings):

• 100% of the executive officer’s then-outstanding and unvested equity awards granted in 2020 through 2022 or in connection with his or her hiring or promotion, as applicable, will become fully vested and exercisable and any applicable performance goals will be deemed achieved at 100% of target levels;

• A lump sum cash amount equal to one year (or for Mr. Huffman, 18 months) of the executive officer’s base salary in effect immediately prior to the termination (or if the termination is due to a resignation for good reason based on a material reduction in base salary, then the executive officer’s annual base salary in effect immediately prior to such reduction) or the change of control, whichever is greater; and

TABLE OF CONTENTS

• Payment or reimbursement of continued health coverage for the executive officer and the executive officer’s eligible dependents under COBRA for a period of up to 12 months (or for Mr. Huffman, 18 months) or a taxable lump sum payment in lieu of payment or reimbursement, as applicable.

If we terminate an executive officer’s employment other than for “cause,” death, or “disability” outside of the applicable change of control period, such executive officer will be eligible to receive the following severance benefits (less applicable tax withholdings):

• A lump sum cash amount equal to six months (or for Mr. Huffman, 12 months) of the executive officer’s base salary in effect immediately prior to the termination; and

• Payment or reimbursement of continued health coverage for the executive officer and the executive officer’s eligible dependents under COBRA for a period of up to six months (or for Mr. Huffman, 12 months) or a taxable lump sum payment in lieu of payment or reimbursement, as applicable.

To receive the severance benefits upon a qualifying termination, an executive officer must sign and not revoke our standard separation agreement and release of claims within the timeframe set forth in the Policy. If any of the payments provided for under the Policy or otherwise payable to an executive officer would constitute “parachute payments” within the meaning of Section 280G of the Code and would be subject to the related excise tax under Section 4999 of the Code, then the executive officer will be entitled to receive either full payment of benefits or such lesser amount which would result in no portion of the benefits being subject to the excise tax, whichever results in the greater amount of after-tax benefits to him or her. The Policy does not require us to provide any tax gross-up payments to any executive officer.

On March 5, 2023, we entered into a separation agreement and release with Mr. Huffman in connection with his separation from the Company, effective as of March 6, 2023. Because Mr. Huffman’s separation was a termination without cause under the Policy, in accordance with Mr. Huffman’s existing rights under the Policy for a termination without cause, that separation agreement provides for payment of 12 months of salary and continuation of benefits for 12 months, as well as accrued compensation through the date of Mr. Huffman’s departure. In addition, pursuant to that separation agreement, Mr. Huffman has agreed to provide certain consulting services for 12 months following the end of his employment with the Company during which time his time-based equity awards will continue to vest based on the original terms of such awards and he will be paid $80,000 in consulting fees.

(3) Consists of 16,421,759 shares of our common stock reserved for issuance under our 2016 Plan and 926,972 shares of our common stock reserved for issuance under our 2018 Employee Stock Purchase Plan. Our 2016 Plan provides that on the first day of each fiscal year beginning with the 2017 fiscal year, the number of shares of our common stock available for issuance thereunder will be increased in an amount equal to the least of (i) 6,196,000 shares, (ii) 5% of the total number of shares of our common stock outstanding on the last day of the immediately preceding fiscal year or (iii) a lower number of shares determined by our Board or a committee thereof. On January 1, 2023, the number of shares of our common stock reserved for issuance under our 2016 plan increased by 3,000,841 shares pursuant to this provision. This increase is not reflected in the table above.

Anchor CEO Pay Ratio

Under rules adopted pursuant to the Dodd-Frank Act, we are required to calculate and disclose the total compensation paid to our median paid employee, as well as the ratio of the total compensation paid to the median employee as compared to the total compensation paid to our Chief Executive Officer (the “CEO Pay Ratio”). The paragraphs that follow describe our methodology and the resulting CEO Pay Ratio.

Measurement Date

We identified the median employee using our employee population on November 1, 2022 (including all employees, whether employed on a full-time, part-time, seasonal or temporary basis).

Consistently Applied Compensation Measure (CACM)

Under the relevant rules, we are required to identify the median employee by use of a “consistently applied compensation measure,” or CACM. We chose a CACM that closely approximates the annual target total direct compensation of our employees. Specifically, we identified the median employee by aggregating, for each employee: a) annual base pay, b) annual target cash incentive opportunity, and c) the estimated grant date fair value for equity awards granted as of November 1, 2022. In identifying the median employee, we converted compensation amounts paid in foreign currencies based on the applicable year-to-date average exchange rate as of November 1, 2022, and annualized the compensation values of individuals that joined our Company during 2022. We did not exclude workers in non-U.S. countries and did not make any cost-of-living adjustments.

Methodology and Pay Ratio

After applying our CACM methodology, we identified the median employee. Once the median employee was identified, we calculated the median employee’s annual target total direct compensation in accordance with the requirements of the Summary Compensation Table.

Our median employee compensation as calculated using Summary Compensation Table requirements was $187,628. Our Chief Executive Officer’s compensation as reported in the Summary Compensation Table was $21,871,907. Therefore, our CEO Pay Ratio for 2022 is approximately 117 to 1.

This information is being provided for compliance purposes and is a reasonable estimate calculated in a manner consistent with SEC rules, based on our internal records and the methodology described above. The SEC rules for identifying the median compensated employee allow companies to adopt a variety of methodologies, to apply certain exclusions and to make reasonable estimates and assumptions that reflect their employee populations and compensation practices. Accordingly, the pay ratio reported by other companies may not be comparable to the pay ratio reported above, as other companies have different employee populations and compensation practices and may use different methodologies, exclusions, estimates and assumptions in calculating their own pay ratios. Neither the Compensation Committee nor management of the Company used the CEO Pay Ratio measure in making compensation decisions.

TABLE OF CONTENTS

Description of Relationships Between Compensation Actually Paid and Performance

Compensation Actually Paid, as determined under rules adopted pursuant to the Dodd-Frank Act and reflected in the Pay Versus Performance table above (“CAP”) for our CEOs, and cumulative total shareholder return, were both lower in 2022 and 2021 relative to 2020. Our CEO CAP was higher in 2022 than in 2021, while our cumulative TSR was lower in 2022 than in 2021, but this was largely due to the year-end fair value of performance-based equity awards (including retention awards) granted to Mr. Huffman in 2022. As disclosed above under the Section titled “Compensation Discussion and Analysis – Individual Compensation Elements – Long-Term Equity Compensation,” because Mr. Huffman’s employment terminated effective March 6, 2023, he forfeited the majority of these awards (including all such retention awards).

Our average NEO CAP was also lower in 2022 and 2021 relative to 2020, but, in contrast to our CEO CAP, our average NEO CAP saw a smaller increase from 2021 to 2022. This smaller increase is also largely due to our 2022 grants of retention awards. Our average NEO CAP figures also reflect that the NEOs included in each year, as determined under the relevant rules, are different in each of the disclosed years.

During the three-year period covered by this disclosure, our cumulative TSR measured for each disclosed year outperformed the cumulative TSR of the S&P 500 Software & Services Select Index measured on the same basis.

Our net income was lower in 2021 relative to 2020 and then increased in 2022 so that net income in 2022 was higher relative to each of 2021 and 2020. These changes are directionally aligned with changes in our CEO CAP and average NEO CAP over these years.

Our revenue increased each year from 2020 to 2022. These increases are not directionally aligned with overall decreases in our CEO CAP and average NEO CAP from 2020 to 2022, but are directionally aligned with increases in our CEO CAP and average NEO CAP from 2021 to 2022.

TABLE OF CONTENTS

Section 145 of the General Corporation Law of the State of Delaware provides that a corporation may indemnify any person made a party to an action by reason of the fact that he or she was a director, executive officer, employee or agent of the corporation or is or was serving at the request of a corporation against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by him or her in connection with such action if he or she acted in good faith and in a manner he or she reasonably believed to be in, or not opposed to, the best interests of the corporation and, with respect to any criminal action or proceeding, had no reasonable cause to believe his or her conduct was unlawful, except that, in the case of an action by or in right of the corporation, no indemnification may generally be made in respect of any claim as to which such person is adjudged to be liable to the corporation.

We have entered into indemnification agreements with our directors and executive officers, in addition to the indemnification provided for in our amended and restated certificate of incorporation and amended and restated bylaws, and intend to enter into indemnification agreements with any new directors and executive officers in the future.

We have purchased and intend to maintain insurance on behalf of each and any person who is or was one of our directors or officers against any loss arising from any claim asserted against him or her and incurred by him or her in any such capacity, subject to certain exclusions.

Anchor Policies and Procedures for Related Party Transactions

In connection with our initial public offering, our Audit Committee and our Board approved a Related Party Transactions Policy which provides that our Audit Committee is responsible for reviewing and approving any related party transaction, taking into account whether the transaction is on an arms-length basis, whether there are business reasons for the transaction, whether the transaction would impair a director’s independence and whether the related party transaction would present an improper conflict of interest. The Related Party Transaction Policy applies to any transaction, arrangement or relationship, or any series of similar transactions, arrangements or relationships, in which we are to be a participant, the amount involved exceeds $120,000 and a related person had or will have a direct or indirect material interest. Our full Board (with any interested director recusing him or herself) reviewed and approved our related party transactions prior to our initial public offering and following our initial public offering, our Audit Committee will approve all of our related party transactions.

We believe that we have executed all the transactions described above on terms no less favorable to us than we could have obtained from unaffiliated third parties. It is our intention to ensure that all future related party transactions are approved by our Audit Committee, and are on terms no less favorable to us than those that we could obtain from unaffiliated third parties.
