PROXY STATEMENT

INFORMATION CONCERNING VOTING AND SOLICITATION

General

Your proxy is solicited on behalf of the board of directors of ON24, Inc., a Delaware corporation (“ON24,” the “Company,” “we,” “us” or “our”), for use at our 2025 Annual Meeting of Stockholders (the “Annual Meeting”) to be held on June 20, 2025, at 8:30 a.m., Pacific Time, or at any continuation, postponement or adjournment thereof, for the purposes discussed in this proxy statement, as well as any business properly brought before the Annual Meeting. Proxies are solicited to give all stockholders of record an opportunity to vote on matters properly presented at the Annual Meeting. The Annual Meeting will be held in person at our corporate headquarters at 50 Beale Street, 8th Floor, San Francisco, California 94105. You will have the ability to submit questions during the Annual Meeting.

We have elected to provide access to our proxy materials over the Internet. Accordingly, on or about April 29, 2025, we are commencing delivery of a Notice of Internet Availability of Proxy Materials to most of our stockholders of record, and paper copies of the proxy materials to certain other stockholders of record. All stockholders will have the ability to access the proxy materials on the website referred to in the notice or request to receive a printed set of the proxy materials. You can find instructions on how to request a printed copy by mail or electronically on the notice and on the website referred to in the notice, including an option to request paper copies on an ongoing basis. Although we encourage stockholders to review our proxy materials in electronic form, we will deliver to those stockholders entitled to vote at the Annual Meeting who have properly requested paper copies of such materials.

Availability of Proxy Materials for the 2025 Annual Meeting

Our proxy materials are available at www.ProxyVote.com. This website address contains: the Notice of Annual Meeting of Stockholders, the proxy statement and proxy card sample and the 2024 Annual Report on Form 10-K. You are encouraged to access and review all of the important information contained in the proxy materials before voting.

Who Can Vote, Outstanding Shares

Record holders of our common stock as of the close of business on April 23, 2025, the record date for the Annual Meeting (the “Record Date”), are entitled to vote at the Annual Meeting on all matters to be voted upon. As of the Record Date, there were 42,474,461 shares of our common stock outstanding. On each matter presented to our stockholders for vote, the holders of common stock are entitled to one vote per share held as of the Record Date.

Voting of Shares

You may vote at the Annual Meeting or via the Internet, via telephone at 1-800-690-6903 or by submitting a proxy. The method of voting by proxy differs depending on whether you are (1) viewing our proxy materials via the Internet or received a paper copy and (2) a record holder or hold your shares in “street name.”

Record Holder. If you hold your shares of common stock as a record holder and you are viewing our proxy materials via the Internet, you may vote by submitting a proxy over the Internet by following the instructions on the website referred to in the Notice of Internet Availability of Proxy Materials previously delivered to you. If you hold your shares of common stock as a record holder and you received a paper copy of our proxy materials, you may vote your shares by completing, dating and signing the proxy card that was included with the proxy statement and promptly returning it in the pre-addressed, postage paid envelope provided to you, or by submitting a proxy over the Internet or by telephone by following the instructions on the proxy card.

Hold in Street Name. If you hold your shares of common stock in street name, which means your shares are held of record by a broker, bank or other nominee (each, a “broker”), you will receive a notice from your broker that includes instructions on how to vote your shares. Your broker will allow you to deliver your voting instructions over the Internet and may also permit you to vote by telephone. In addition, you may request paper copies of the proxy statement and proxy card from your broker by following the instructions on the notice provided by your broker.

General. If you vote through the Internet or by telephone, you should be aware that you may incur costs such as usage charges from telephone companies or Internet service providers and that these costs must be borne by you. If you vote through these facilities, then you need not return a written proxy card by mail. The cost of soliciting proxies will be borne by us. We may reimburse brokers representing beneficial owners for their reasonable out-of-pocket costs. We may use the services of our officers, directors and others to solicit proxies, personally or by telephone, facsimile or electronic mail, without additional compensation.

YOUR VOTE IS VERY IMPORTANT. We encourage you to submit your proxy even if you plan to attend the Annual Meeting in person. If you are a stockholder of record on the Record Date, you are invited to attend the Annual Meeting in person and you may vote your shares during the Annual Meeting. If you properly give your proxy and submit it to us in time to vote, one of the individuals named as your proxy will vote your shares as you have directed.

All shares entitled to vote and represented by properly submitted proxies (including those submitted electronically, telephonically and in writing), and not revoked or superseded, will be voted at the Annual Meeting in accordance with the instructions indicated on those proxies. If no direction is indicated on a proxy, your shares will be voted as follows:

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

•FOR the ratification of the selection of KPMG LLP as our independent registered public accounting firm.

The proxy gives each of Sharat Sharan, Steven Vattuone and William Weesner discretionary authority to vote your shares in accordance with their best judgment with respect to all additional matters that might come before the Annual Meeting. If you receive more than one proxy card or Notice of Internet Availability of Proxy Materials, it means you hold shares that are registered in more than one account. To ensure that all of your shares are voted, sign and return each proxy card or, if you submit a proxy by telephone or the Internet, submit one proxy for each proxy card or Notice of Internet Availability of Proxy Materials you receive.

Revocation of Proxy

If you are a stockholder of record, you may revoke your proxy at any time before your proxy is voted at the Annual Meeting by taking any of the following actions:

•delivering to our Corporate Secretary a signed written notice of revocation, bearing a date later than the date of the proxy, stating that the proxy is revoked;

•signing and delivering a new paper proxy, relating to the same shares and bearing a later date than the original proxy;

•submitting another proxy by telephone or over the Internet (your latest telephone or Internet voting instructions are followed); or

•attending the Annual Meeting in person and voting, although attendance at the Annual Meeting will not, by itself, revoke a proxy.

Written notices of revocation and other communications with respect to the revocation of Company proxies should be addressed to:

ON24, Inc.

50 Beale Street, 8th Floor

San Francisco, CA 94105

Attention: Corporate Secretary

If your shares are held in “street name,” you may change your vote by submitting new voting instructions to your broker. You must contact your broker to find out how to do so. See below regarding how to vote live if your shares are held in street name.

Attendance at the Annual Meeting

We are excited to invite stockholders to join us at our corporate headquarters at 50 Beale Street, 8th Floor, San Francisco, California 94105 for this year’s Annual Meeting. Admission to the Annual Meeting will be limited to our stockholders of record, persons holding proxies from our stockholders and beneficial owners of our common stock.

If you are a stockholder of record (or a registered stockholder), we will verify your ownership at the meeting in our list of stockholders as of the Record Date (April 23, 2025). If your shares are held through a broker, you must bring proof of your ownership of the shares as of the Record Date (April 23, 2025). This proof could consist of, for example, a brokerage firm account statement or a letter from your broker confirming your ownership as of the Record Date.

In order to allow ample time for check-in, you will need to plan to arrive at 50 Beale Street, 8th Floor, San Francisco, California 94105 on June 20, 2025, no later than 8:00 a.m. Pacific Time. Next, at the registration table, you will need to present a government-issued photo identification, along with proof of your stock ownership.

Upon completion of these steps, you will be issued a visitor badge, which you must wear at all times. Prohibited items include backpacks, purses or bags larger than 12”x 6”x 12,” coolers and camera cases.

Visitors must always be escorted by ON24, Inc. security or personnel, and should return the visitor badge when leaving the building after the Annual Meeting is adjourned.

Broker Non-Votes

Brokers who hold shares of common stock in “street name” for a beneficial owner of those shares typically have the authority to vote in their discretion on “routine” proposals when they have not received instructions from beneficial owners. However, brokers are not allowed to exercise their voting discretion with respect to the election of directors or for the approval of other matters that are considered “non-routine” matters without specific voting instructions from the beneficial owner. These non-voted shares are referred to as “broker non-votes.” If your broker holds your common stock in “street name,” your broker will vote your shares on “non-routine” proposals only if you provide instructions on how to vote by filling out the voter instruction form sent to you by your broker with this proxy statement. Only Proposal No. 2 (ratifying the appointment of our independent registered public accounting firm) is considered a routine matter. Proposal No. 1 (election of directors) is not considered a routine matter and, without your instruction, your broker cannot vote your shares for the election of directors.

Quorum and Votes Required

The inspector of elections appointed for the Annual Meeting will tabulate votes cast by proxy or at the Annual Meeting. The inspector of elections will also determine whether a quorum is present. In order to constitute a quorum for the conduct of business at the Annual Meeting, a majority of the votes entitled to be cast represented in person or by proxy at the Annual Meeting must be present in person or represented by proxy at the Annual Meeting. Shares that abstain from voting on any proposal, or that are represented by broker non-votes, will be treated as shares that are present and entitled to vote at the Annual Meeting for purposes of determining whether a quorum is present.

Proposal No. 1: Election of Directors. A plurality of the votes cast in the election of directors at the Annual Meeting is required for the election of directors. Accordingly, the two Class I director nominees receiving the highest number of votes will be elected. “Withhold” votes and broker non-votes will have no effect on the outcome of the election of directors. Stockholders are not permitted to cumulate votes with respect to the election of directors.

Proposal No. 2: Ratification of Independent Registered Public Accounting Firm. The number of votes “for” must exceed the number of votes “against” in order to ratify the selection of KPMG LLP as our independent registered public accounting firm. Abstentions are considered to be votes not cast on this proposal and thus will have no effect. Brokers generally have discretionary authority to vote on the ratification of our independent registered public accounting firm, thus broker non-votes are not expected to result from the vote on Proposal No. 2.

In their discretion, the proxy holders named in the proxy are authorized to vote on any other matters that may properly come before the Annual Meeting and at any continuation, postponement or adjournment thereof. The board of directors knows of no other items of business that will be presented for consideration at the Annual Meeting other than those described in this proxy statement.

Solicitation of Proxies

Our board of directors is soliciting proxies for the Annual Meeting from our stockholders. We will bear the entire cost of soliciting proxies from our stockholders. In addition to the solicitation of proxies by delivery of the Notice of Internet Availability of Proxy Materials or proxy statement, we will request that brokers that hold shares of our common stock, which are beneficially owned by our stockholders, send Notices of Internet Availability of Proxy Materials, proxies and proxy materials to those beneficial owners and secure those beneficial owners’ voting instructions. We will reimburse those record holders for their reasonable expenses. We may use several of our regular employees, who will not be specially compensated, to solicit proxies from our stockholders, either personally or by telephone, Internet, facsimile or special delivery letter. It is contemplated that additional solicitation of proxies will be made in the same manner under the engagement and direction of Okapi Partners, 1212 Avenue of the Americas, Floor 24, New York, NY 10036, at an anticipated cost of $14,000, plus reimbursement of out-of-pocket expenses.

Communicating with our Board of Directors

Those who wish to communicate with our board of directors or specific individual directors may do so by letter sent to our principal executive offices, addressed to the attention of our Corporate Secretary. Our Corporate Secretary reviews all communications and forwards them to the intended recipient(s) consistent with a screening policy, which provides that sales materials, routine items, and items unrelated to the duties and responsibilities of the board of directors are not relayed to directors.

Stockholder List

A list of stockholders eligible to vote at the Annual Meeting will be available for inspection, for any purpose germane to the Annual Meeting, at our principal executive offices during regular business hours for a period of no less than ten days prior to the Annual Meeting. Information required to gain access to the list of stockholders eligible will also be provided upon request during the same time period.

Forward-Looking Statements

This proxy statement contains “forward-looking statements” (as defined in the Private Securities Litigation Reform Act of 1995). These statements are based on our current expectations and involve risks and uncertainties, which may cause results to differ materially from those set forth in the statements. The forward-looking statements may include statements regarding actions to be taken by us. We undertake no obligation to publicly update any forward-looking statement, whether as a result of new information, future events or otherwise, except as required by law. Forward-looking statements should be evaluated together with the many uncertainties that affect our business, particularly those mentioned in the risk factors in Item 1A of our Annual Report on Form 10-K for the year ended December 31, 2024, and in our periodic reports on Form 10-Q and our current reports on Form 8-K.

CORPORATE GOVERNANCE

Our board of directors consists of nine members. Our directors hold office until their successors have been elected and qualified or until the earlier of their resignation or removal.

On December 17, 2024, Irwin Federman notified the Company that he will not stand for reelection to the Board at the Annual Meeting. Mr. Federman will continue to serve on the Board until the Annual Meeting. In connection with Mr. Federman’s departure, on December 17, 2024, the Board also resolved to reduce the size of the Board from nine directors to eight directors, effective upon the Annual Meeting.

Cynthia Paul and Ronald Mitchell were appointed to our board of directors in March 2023 in connection with the Cooperation Agreement with Indaba Capital Management, L.P. (“Indaba”), dated March 11, 2023. Ms. Paul was elected at the 2023 annual meeting of stockholders (the “2023 Annual Meeting”) as a Class II director with a term expiring at the 2026 annual meeting of stockholders (the “2026 Annual Meeting”). Mr. Mitchell serves as a Class I director with a term expiring at the Annual Meeting. On March 17, 2025, the Company and Indaba came to an arrangement that if the Board (i) renominated Mr. Mitchell for election at the Annual Meeting and recommended, supported and solicited proxies for the election of Mr. Mitchell at the Annual Meeting in the same manner as for all other director nominees, and (ii) maintains Mr. Mitchell as a member of the Nominating and Corporate Governance Committee of the Board, in exchange, Indaba agreed that it would not conduct a proxy fight at the Annual Meeting and it will not conduct any public campaign or make any public statements regarding the Issuer before the earlier of: (i) August 15, 2025; or (ii) the day after the public release of the Issuer's earnings for the second quarter of 2025.

Our Certificate of Incorporation and Bylaws provide that our directors may be removed from our board of directors with or without cause by the affirmative vote of at least 66 2/3% of the voting power of all of our then-outstanding shares of capital stock entitled to vote generally in the election of directors, voting together as a single class. In addition, our Certificate of Incorporation provides that, subject to the rights granted to one or more series of preferred stock then outstanding, any newly created directorship on the board of directors that results from an increase in the number of directors and any vacancies on our board of directors will be filled only by the affirmative vote of a majority of the remaining directors, even if less than a quorum, or by a sole remaining director.

Director Independence

Our board of directors has determined that each member of our board of directors, except Sharat Sharan, is an “independent director,” as defined under the rules of the New York Stock Exchange (“NYSE”) and the Securities and Exchange Commission (“SEC”). In making this determination, our board of directors applied the standards set forth under Rule 10A-3 of the Securities Exchange Act of 1934, as amended (“Exchange Act”) and related SEC and NYSE rules. Our board of directors considered all relevant facts and circumstances known to it in evaluating the independence of these directors, including their current and historical employment, any compensation we have paid to them, any transactions we have had with them, their beneficial ownership of our capital stock, their ability to exert control over us, all other material relationships they have had with us and the same facts with respect to their immediate families.

The composition and functioning of our board of directors and each of our committees complies with all applicable requirements of the NYSE and the rules and regulations of the SEC.

Declassifying Board of Directors

In accordance with the declassification amendment to our Certificate of Incorporation that our stockholders approved at the 2023 Annual Meeting, the declassification of our board of directors is being phased-in. Beginning with the class of directors standing for election at the 2024 Annual Meeting, directors are being elected for shorter terms until our board of directors is fully declassified at the 2026 annual meeting of stockholders (the “2026 Annual Meeting”) and at which point directors will stand for one-year terms. Until such time, the board of directors is divided into three classes with staggered terms, as follows:

•the Class I directors are Irwin Federman, Ronald Mitchell and Anthony Zingale, and their terms will expire at the Annual Meeting. At the Annual Meeting, each of Mr. Mitchell and Mr. Zingale will stand for election to serve a one-year term that will expire at the 2026 Annual Meeting;

•the Class II directors are Teresa Anania, Cynthia Paul and Barry Zwarentstein, and their terms will expire at the 2026 Annual Meeting; and

•the Class III directors are Anil Arora, Sharat Sharan and Dominique Trempont, and their terms will expire at the 2026 Annual Meeting.

Commencing with the election of directors at the 2026 Annual Meeting and at each annual meeting thereafter, our board of directors will no longer be classified and all directors will be elected to serve one-year terms. Until the board of directors is fully declassified, 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. The current classification of our board of directors may have the effect of delaying or preventing changes in control of our company.

Board Leadership Structure

Our board of directors has adopted corporate governance guidelines covering, among other things, the duties and responsibilities of and independence standards applicable to our directors and board committee structures and responsibilities. These guidelines are available on the “Governance” section of our website at https://investors.on24.com/governance/governance-documents. Our Bylaws and Corporate Governance Guidelines provide our board of directors with flexibility to combine or separate the positions of Chair of the Board and Chief Executive Officer. If the Chair of the Board is also a director who does not otherwise qualify as an independent director, the independent directors may elect from among themselves a Lead Independent Director who calls and chairs the regularly scheduled executive sessions of the independent directors and serves as a non-exclusive liaison among the independent directors and the other members of our board of directors. Sharat Sharan is the current Chair of the Board and Chief Executive Officer, and Anil Arora currently serves as the Lead Independent Director of our board of directors.

Our board of directors has concluded that our current leadership structure is appropriate at this time. Our board of directors believes that the combined role of Chair of the Board and Chief Executive Officer is appropriate at this time, in light of Mr. Sharan’s extensive experience in overseeing our day-to-day business, supervising our management, regularly communicating with all of our directors, and designing and executing our business strategies since our formation. Mr. Sharan has demonstrated the ability to effectively manage the competing demands for his time such that our board of directors believes he can effectively lead our board of directors. Meanwhile, Mr. Arora has served on our board of directors since April 2022 and has served in several board leadership positions for public companies, has served as a public company Chief Executive Officer, and is one of our independent directors and a member of the nominating and corporate governance committee and the compensation committee, thereby providing a strong, experienced voice for our independent directors. Our board of directors believes this leadership structure provides the appropriate balance of authority between independent and non-independent directors and is an effective governance model for us and for our stockholders at this time.

Attendance by Members of the Board at Meetings

Our board of directors held six meetings during the year ended December 31, 2024. During 2024, all of our then incumbent directors attended at least 75% of the combined total of (1) all board meetings and (2) all meetings of committees of our board of which the incumbent director was a member. Currently, we do not maintain a formal policy regarding director attendance at the Annual Meeting; however, we invite and encourage each member of our board of directors to attend our annual meetings of stockholders. Seven of our then incumbent directors joined our 2024 annual meeting of stockholders in person or by telephone.

Executive Sessions

Our non-management directors meet regularly in executive sessions without management, to consider such matters as they deem appropriate. Our Lead Independent Director, Mr. Arora, presides over all executive sessions.

Committees of our Board of Directors

Our board of directors has established an audit committee, a compensation committee and a nominating and corporate governance committee, each of which operates pursuant to a written charter adopted by our board of directors. Our board of directors may also establish other committees from time to time to assist the board of directors. The composition and functioning of all of our committees comply with all applicable requirements of the Sarbanes-Oxley Act, NYSE and SEC rules and regulations. Each committee has a charter, which is available on the “Governance” section of our website at https://investors.www.on24.com/governance/governance-documents. Information contained on, or that can be accessed through, our website is not part of and is not incorporated by reference into this proxy statement, and you should not consider information on our website to be part of this proxy statement.

Audit Committee

Ms. Anania and Messrs. Federman, Trempont and Zwarenstein serve on the audit committee, which is chaired by Mr. Zwarenstein. The audit committee met four times during 2024. Our board of directors has determined that each member of the audit committee is “independent” as that term is defined in the SEC and the NYSE rules, meets the heightened independence requirements for audit committees required under Section 10A of the Exchange Act and related SEC and the NYSE rules, and has sufficient knowledge in financial and auditing matters to serve on the audit committee. Our board of directors has designated Mr. Zwarenstein as an “audit committee financial expert,” as defined under the applicable rules of the SEC. The audit committee’s responsibilities include:

•appointing, approving the compensation of and assessing the independence of our independent registered public accounting firm;

•pre-approving audit and permissible non-audit services, and the terms of such services, to be provided by our independent registered public accounting firm;

•reviewing the overall audit plan with our independent registered public accounting firm and members of management responsible for preparing our financial statements;

•reviewing and discussing with management and our independent registered public accounting firm our annual and quarterly financial statements and related disclosures as well as critical accounting policies and practices used by us;

The nominating and corporate governance committee met four times during 2024. Our board of directors has determined that each member of the nominating and corporate governance committee is “independent” as defined in the NYSE rules.

The nominating and corporate governance committee will consider director candidates recommended by stockholders on the same basis that it evaluates other nominees for director. Stockholders who wish to recommend a candidate to our nominating and corporate governance committee for consideration for nomination should send to us, at our principal executive offices, information regarding the candidate. In order to identify potential director candidates, the committee may utilize its or our existing networks or retain a third-party recruiting firm.

Pursuant to our Corporate Governance Guidelines, when considering the nominees for election as directors at an annual meeting or to fill an existing vacancy, the nominating and corporate governance committee reviews the needs of our board of directors for various skills, background, experience and expected contributions and the qualification standards established from time to time by the nominating and corporate governance committee. When reviewing potential nominees, including incumbents, the nominating and corporate governance committee considers the perceived needs of our board of directors as a whole and the candidate’s relevant background, experience, skills and expected contributions to our board of directors. The nominating and corporate governance committee’s goal is to assemble a board of directors that brings to our company a diversity of experience in areas that are relevant to our activities. Directors should possess the highest personal and professional ethics, integrity and values and be committed to representing the long-term interests of our stockholders. They must have an inquisitive and objective outlook and mature judgment. They must also have experience in positions with a high degree of responsibility and be leaders in the companies and institutions with which they are, or have been, affiliated. When

considering the nomination of directors, the nominating and corporate governance committee considers the diversity of its directors and nominees in terms of knowledge, experience, background, skills, expertise and other demographic factors. Director candidates must have sufficient time available in the judgment of the nominating and corporate governance committee to perform all responsibilities that will be expected of them as members of our board of directors and its committees. We expect our directors to rigorously prepare for, attend and participate in all meetings of our board of directors and their applicable committees.

None of the members of our compensation committee has during the prior fiscal year been one of our officers or employees or had a relationship requiring disclosure under “Relationships and Related Party Transactions.” None of our executive officers currently serves, nor in the past fiscal year has served, as a member of the board of directors or compensation committee of any entity that has one or more executive officers serving on our board of directors or compensation committee.

INSIDER TRADING POLICY

We have adopted an insider trading policy that applies to our employees, directors, officers, and consultants, their family members and entities over which such individuals have or share voting or investment control, in addition to anyone who receives material non-public information (“MNPI”) from an ON24 insider or is otherwise designated under the policy (collectively, “covered persons”). The insider trading policy also applies to ON24 itself when it transacts in securities, including generally prohibiting the grant of option awards while in possession of MNPI and providing guidelines around repurchases of our securities. Our insider trading policy is designed to promote compliance with applicable insider trading laws, rules and regulations and applicable listing standards. Among other things, our insider trading policy (i) prohibits trading by covered persons in our securities while in possession of MNPI about ON24, except under trading plans that meet the requirements of Rule 10b5-1 under the Exchange Act, or in the securities of any other company with respect to which such covered persons have received MNPI as a result of their relationship with or employment by ON24, (ii) prohibits disclosing MNPI to others who may trade in ON24 securities or in the securities of any other publicly traded company on the basis of such MNPI, and (iii) specifies our blackout periods (and who is subject to such periods), our insider trading windows and pre-clearance procedures (and who is subject to such procedures) and requirements and procedures regarding Rule 10b5-1 trading plans. A copy of our insider trading policy was filed as Exhibit 19 to our 2024 Annual Report on Form 10-K filed with the SEC on March 13, 2025.

CODE OF CONDUCT

We have a written code of business conduct and ethics that applies to our directors, officers and employees, including our principal executive officer, principal financial officer, principal accounting officer or controller, or persons performing similar functions. A copy of the code is available on the “Governance” section of our website at https://investors.on24.com/governance/governance-documents. In addition, we intend to post on our website all disclosures that are required by law or the NYSE listing standards concerning any amendments to, or waivers from, any provision of the code. If we make any substantive amendments to, or grant any waivers from, the code for any officer or director, we will disclose the nature of such amendment or waiver on our website or in a current report on Form 8-K.

The assumptions used in calculating the grant date fair value of equity awards are set forth in Note 11 to our audited consolidated financial statements filed with our Annual Report on Form 10-K for the year ended December 31, 2024.

Our board of directors has adopted a non-employee director compensation policy that is designed to enable us to attract and retain, on a long-term basis, highly qualified non-employee directors (the “Non-Employee Director Compensation Policy”). We pay the annual fees set forth below to non-employee directors:


						Annual Fee ($)
Member of the Audit Committee						10,000
Chair of the Audit Committee						25,000
Member of the Compensation Committee						6,000
Chair of the Compensation Committee						15,000
Member of the Nominating and Corporate Governance Committee						3,750
Chair of the Nominating and Corporate Governance Committee						10,000
Lead Independent Director						40,000
Annual Board Service Retainer						50,000

In addition, each new non-employee director who joins our board of directors automatically receives an RSU for common stock having a value of $450,000 based on the average fair market value of our common stock for the 20 trading days prior to and ending on the date of grant (the “Initial RSU”). Each Initial RSU will vest over three years, with one-third of the Initial RSU vesting on the first, second, and third anniversary of the date of grant. Moreover, on the date of each annual meeting of our stockholders, each person who is then a non-employee director will automatically receive an RSU for common stock having a value of $175,000 based on the average fair market value of the underlying common stock for the 20 trading days prior to and ending on the date of grant (the “Annual RSU”). Each Annual RSU will vest on the earlier of (i) the date of the following

year’s annual meeting of our stockholders (or the date immediately prior to the next annual meeting of our stockholders if the non-employee director’s service as a director ends at such meeting due to the director’s failure to be re-elected or the director not standing for re-election); or (ii) the first anniversary of the date of grant. Vesting of Initial RSUs and Annual RSUs is subject to the non-employee director’s continuous service on each applicable vesting date. For each non-employee director who remains in continuous service with us until immediately prior to a “change of control” (as defined in our 2021 Equity Incentive Plan (the “2021 Plan”)), the shares subject to his or her then outstanding equity awards will become fully vested as of immediately prior to the change of control.

We will reimburse each non-employee director for ordinary, necessary, and reasonable out-of-pocket travel expenses to cover in-person attendance at, and participation in, meetings of our board of directors and any of its committees.

PROPOSAL 1

ELECTION OF DIRECTORS

Pursuant to our Certificate of Incorporation and our Bylaws, the total number of directors constituting the board of directors is fixed from time to time by the board. In December 2024, the board of directors resolved to reduce the size of the Board from nine directors to eight directors, effective upon the Annual Meeting. The board of directors is divided into three classes, each containing as nearly as possible an equal number of directors. The current term of office of our Class I directors expires at the Annual Meeting, while the term for our Class II directors and Class III directors will expire at our 2026 Annual Meeting. Commencing with the election of directors at our 2026 Annual Meeting and at each annual meeting thereafter, our board of directors will no longer be classified and all directors will be elected to serve one-year terms. Based upon the recommendation of our nominating and corporate governance committee, the board has nominated Ronald Mitchell and Anthony Zingale, both current Class I directors, for re-election at the Annual Meeting. Each director elected at the Annual Meeting will serve a one-year term expiring at our 2026 Annual Meeting and until his successor is duly elected and qualified as a Class I Director, or until his earlier death, resignation or removal. At the Annual Meeting, proxies cannot be voted for a greater number of individuals than the two nominees named in this proxy statement.

The board of directors and the nominating and corporate governance committee believe the skills, qualities, attributes and experience of our directors provide us with business acumen and a diverse range of perspectives to engage each other and management to effectively address our evolving needs and represent the best interests of our stockholders.

Vacancies on the board, including any vacancy created by an increase in the size of the board, may be filled only by a majority of the directors remaining in office, even though less than a quorum of the board, or a sole remaining director. A director elected by the board to fill a vacancy will serve until the next election of the class of directors for which such director was chosen and until such director’s successor is elected and qualified, or until such director’s earlier retirement, resignation, disqualification, removal or death.

If any nominee should become unavailable for election prior to the Annual Meeting, an event that currently is not anticipated by the board of directors, the proxies will be voted in favor of the election of a substitute nominee or nominees proposed by the board of directors or the number of directors may be reduced accordingly. Each nominee has agreed to serve if elected and the board of directors has no reason to believe that any nominee will be unable to serve.

(1)Effective as of July 1, 2025

Bonus and Commission

We grant annual incentives intended to create a direct correlation between the executive’s role and responsibilities and the ability to earn variable pay. During the fiscal year ended December 31, 2024, Sharat Sharan and Steven Vattuone were eligible to earn annual incentives based on the achievement of a weighted mix of corporate performance objectives relating to net ARR growth and non-GAAP EBITDA. James Blackie does not participate in the same annual incentive program and instead, as our Chief Revenue Officer, participates in a commission program, pursuant to which he receives commissions based on a weighted mix of bookings measures. For the fiscal year ended December 31, 2024, Sharat Sharan, Steven Vattuone and James Blackie had an annual opportunity targeted at 95%, 70% and 90%, respectively, of each’s base salary. We have based the annual opportunity for each of our named executive officers entirely on the achievement of these objectives.

Long-Term Equity Incentive Awards

We grant equity incentive awards when we determine it is appropriate to do so in order to align the interests of our named executive officers with those of our stockholders and to motivate them to make impactful contributions to our performance. These awards are all subject to time-based vesting conditions and, in the case of performance awards (PSUs), they are also subject to certain performance conditions.

Employment Arrangements with our Named Executive Officers

Sharat Sharan

We are party to a continuing employment letter with Mr. Sharan, our Chief Executive Officer and a member of our board of directors. The employment letter does not have a specific term. Mr. Sharan’s base salary is $520,000 subject to annual review and his annual target bonus is $495,000. Mr. Sharan is eligible to participate in our standard health and welfare benefits programs.

In the event of an “involuntary termination” or if we terminate his employment without “cause,” Mr. Sharan is entitled to receive, subject to his execution of a general release of claims, a severance payment equivalent to 12 months of his base salary (or 18 months for a “change of control termination”), 100% of his target bonus (or 150% for a “change of control termination”), a pro rata portion of his target bonus for the year, and 12 months of COBRA premiums (18 months in the event of a change of control termination), and 75% of his then unvested equity awards shall immediately vest and become exercisable. In these circumstances, Mr. Sharan will be permitted to purchase any vested portion of those awards through the date those awards are scheduled to expire.

If we consummate a “change of control” while Mr. Sharan is employed or we enter into an agreement to effect a change of control within 90 days following termination of his employment that we ultimately consummate, then immediately prior to the consummation of such change of control, 75% of his then unvested equity awards shall immediately vest and become exercisable. In the event of a change of control termination, all of Mr. Sharan’s unvested equity awards shall immediately vest and become exercisable.

Notwithstanding the terms of Mr. Sharan’s employment letter, we granted 341,404 PSUs and 341,404 RSUs to Mr. Sharan in 2022 and 484,244 PSUs and 484,244 RSUs to Mr. Sharan in 2024 that have different acceleration or vesting provisions than the terms of Mr. Sharan’s employment letter. The RSU agreement provides that, in the event of (i) termination without Cause or an Involuntary Termination, Mr. Sharan will be credited with an additional 12 full months of service, and (ii) a Change in Control, the RSU will be assumed, substituted, or accelerated and if Mr. Sharan is terminated 90 days before or one year following the Change in Control, the RSU will vest in full. The PSU agreement provides that if Mr. Sharan’s service terminates for any reason prior to the end of a performance period, all unvested PSUs are forfeited, except that in the case of a Change in Control a portion of the PSU will vest based on the transaction price and prorated portion of the performance period, with the remainder vesting based on time. Both the RSU agreement and the PSU agreement provide that these terms supersede the terms of Mr. Sharan’s employment letter.

Under Mr. Sharan’s employment letter:

•“Involuntary termination” means (i) his voluntary termination of employment following a material reduction in cash compensation or benefits or the assignment of additional material job responsibilities or a reduction in job responsibilities materially inconsistent with his position and responsibilities prior to a change of control; or the relocation of his workplace by more than 60 miles; (ii) the termination of his employment as a result of his inability to perform the material and substantial duties of his position for a period of 30 days as a result of incapacity due to physical or mental injury or illness; or (iii) the termination of his employment as a result of his death.

•“Cause” means his uncured material breach of any material terms his employment letter, conviction of a felony or entry of a plea of nolo contendere as to a felony, commission of a fraud, repeated unexplained or unjustified absence from the company, willful breach of fiduciary duty, or gross negligence or willful misconduct that has resulted or is likely to result in material damage to the company.

•“Change of control” means our merger, consolidation or similar reorganization with any other corporation or entity, other than a merger or consolidation which would result in our outstanding voting securities continuing to represent at least 50% of the total voting power of the surviving entity immediately after such merger or consolidation, or our sale or disposition of all or substantially all of our assets.

•“Change of control termination” means an involuntary termination or termination without cause occurs during the period starting 90 days prior to the consummation of a change of control and ending on the first anniversary of that change of control.

Steven Vattuone

We are party to a continuing employment letter with Mr. Vattuone, our Chief Financial Officer. The employment letter does not have a specific term and provides that Mr. Vattuone’s employment is at-will. Mr. Vattuone’s current annual base salary is $383,000. Effective July 1, 2025, Mr. Vattuone’s base salary will be $425,000. His target bonus is determined by our compensation committee. Mr. Vattuone is eligible to participate in our standard health and welfare benefits programs.

James Blackie

We are party to a continuing employment letter with Mr. Blackie, our Chief Revenue Officer. The employment letter does not have a specific term and provides that Mr. Blackie’s employment is at-will. Mr. Blackie’s current annual base salary is $475,000 and his target bonus, which is paid as a commission, is determined by our compensation committee. Mr. Blackie is eligible to participate in our standard health and welfare benefits programs.

Executive Severance Program

We have entered into severance program agreements with our executive officers, excluding Mr. Sharan. Under the severance program agreements, if we terminate the employment of our executive officers without “cause,” he or she is entitled to receive a severance payment equivalent to six months of his or her base salary and reimbursement of up to six months of COBRA premiums, in addition to standard entitlements such as earned but unpaid wages, including any bonus he or she is otherwise entitled to, reimbursement for unpaid expenses incurred and payment of other vested benefits.

If, on or within twelve months of a “change in control,” an executive officer’s employment is terminated without “cause,” or if he or she resigns for “good reason,” he or she is entitled to receive a severance payment equivalent to one year of his or her then-current base salary, accelerated vesting of 100% of the shares underlying his or her then-unvested equity awards and reimbursement of up to twelve months of COBRA premiums, in addition to standard entitlements such as earned but unpaid wages, including any bonus he or she is otherwise entitled to, reimbursement for unpaid expenses incurred and payment of other vested benefits.

Under the severance program, “cause” means (i) theft, dishonesty, willful misconduct, breach of fiduciary duty for personal profit, or falsification of any Participating Company documents or records; (ii) the executive’s material failure to abide by our code of conduct or other policies (including, without limitation, policies relating to confidentiality and reasonable workplace conduct); (iii) the executive’s unauthorized use, misappropriation, destruction or diversion of any tangible or intangible asset or corporate opportunity of a ours (including, without limitation, the executive’s improper use or disclosure of our or proprietary information); (iv) any intentional act by the executive which has a material detrimental effect on our reputation or business; (v) the executive’s repeated failure or inability to perform any reasonable assigned duties after written notice from us of, and a reasonable opportunity to cure, such failure or inability; (vi) any material breach by the executive of any employment or service agreement between the executive and us, which breach is not cured pursuant to the terms of such agreement; or (vii) the executive’s conviction (including any plea of guilty or nolo contendere) of any criminal act involving fraud, dishonesty, misappropriation or moral turpitude, or which impairs the executive’s ability to perform his or her duties with us.

Under the severance program, “change in control” means (i) a transaction in which the stockholders of ON24 immediately before the transaction do not retain immediately after the transaction direct or indirect beneficial ownership of more than 50% of the total combined voting power of the outstanding securities entitled to vote generally in the election of Directors or the entity to which all or substantially all of our assets were transferred or (ii) a date specified by the board of directors following approval by the stockholders of a plan of complete liquidation or dissolution of ON24, unless a majority of the members of the board of directors of the continuing, surviving or successor entity or parent thereof, immediately after such transaction is comprised of incumbent directors. This offering will not constitute a change in control under the severance program.

Under the severance program agreement, “good reason” means resignation from employment with us following the occurrence of any of the following events without the executive’s prior written consent: (i) a significant reduction in the executive’s duties, position or responsibilities in effect immediately prior to such reduction, other than where the executive is asked to assume substantially similar duties and responsibilities in a larger entity after such change in control (which may involve a different title); (ii) a material reduction in current base salary; or (iii) a relocation to a worksite that is more than 50 miles from the then-existing worksite.

EMPLOYEE BENEFIT AND EQUITY COMPENSATION PLANS

2021 Equity Incentive Plan

In connection with our IPO, we adopted our 2021 Plan, effective in February 2021. We use it to provide incentives that will assist us to attract, retain, and motivate employees, including officers, consultants, and directors. We may provide these incentives through the grant of stock options, stock appreciation rights, restricted stock, RSUs, performance shares, and units and other cash-based or share-based awards. In addition, the 2021 Plan contains a mechanism through which we may adopt a deferred compensation arrangement in the future.

A total of 6,400,000 shares of our common stock were initially authorized and reserved for future issuance under the 2021 Plan. This reserve automatically increases on January 1, 2022 and each subsequent anniversary through 2031, by an amount equal to the smaller of:

•5.0% of the number of shares of common stock issued and outstanding on the immediately preceding December 31; and

•an amount determined by our board of directors.

Appropriate adjustments will be made in the number of authorized shares and other numerical limits in the 2021 Plan and in outstanding awards to prevent dilution or enlargement of participants’ rights in the event of a stock split or other change in our capital structure. Shares subject to awards which expire or are cancelled or forfeited will again become available for issuance under the 2021 Plan.

The shares available under the 2021 Plan will not be reduced by awards settled in cash, but will be reduced by shares withheld to satisfy tax withholding obligations with respect to stock options and stock appreciation rights (but not other types of awards). The gross number of shares issued upon the exercise of stock appreciation rights or options exercised by means of a net exercise or by tender of previously owned shares will be deducted from the shares available under the 2021 Plan.

The 2021 Plan generally will be administered by the compensation committee of our board of directors. Subject to the provisions of the 2021 Plan, the compensation committee will determine in its discretion the persons (other than the CEO and members of our board of directors) to whom and the times at which awards are granted, the sizes of such awards and all of their terms and conditions. The compensation committee will have the authority to construe and interpret the terms of the 2021 Plan and awards granted under it. The 2021 Plan provides, subject to certain limitations, for indemnification by us of any director, officer, or employee against all reasonable expenses, including attorneys’ fees, incurred in connection with any legal action arising from such person’s action or failure to act in administering the 2021 Plan.

During any year, no non-employee director may be granted one or more awards pursuant to the 2021 Plan which, taken together with any cash compensation paid to such non-employee director during such year, exceeds $1,000,000.

The 2021 Plan authorizes the compensation committee, without further stockholder approval, to provide for the cancellation of stock options or stock appreciation rights with exercise prices in excess of the fair market value of the underlying shares of common stock on the date of grant in exchange for new options or other equity awards with exercise prices equal to the fair market value of the underlying common stock on the date of grant or a cash payment.

Awards may be granted under the 2021 Plan to our employees, including officers, directors, or consultants or those of any present or future parent or subsidiary corporation or other affiliated entity. All awards will be evidenced by a written agreement between us and the holder of the award and may include any of the following:

•Stock options. We may grant non-statutory stock options or incentive stock options (as described in Section 422 of the Code), each of which gives its holder the right, during a specified term (not exceeding ten years) and subject to any specified vesting or other conditions, to purchase a number of shares of our common stock at an exercise price per share determined by the administrator, which may not be less than the fair market value of a share of our common stock on the date of grant.

•Stock appreciation rights. A stock appreciation right (“SAR”), gives its holder the right, during a specified term (not exceeding ten years) and subject to any specified vesting or other conditions, to receive the appreciation in the fair market value of our common stock between the date of grant of the award and the date of its exercise. We may pay the appreciation in shares of our common stock or in cash.

•Restricted stock. The administrator may grant restricted stock awards either as a bonus or as a purchase right at a price determined by the administrator. Shares of restricted stock remain subject to forfeiture until vested, based on such terms and conditions as the administrator specifies. Holders of restricted stock will have the right to vote the shares and to receive any dividends paid, except that the dividends may be subject to the same vesting conditions as the related shares.

•Restricted stock units. Restricted stock units (“RSUs”), represent rights to receive shares of our common stock (or their value in cash) at a future date without payment of a purchase price, subject to vesting or other conditions specified by the administrator. Holders of RSUs have no voting rights or rights to receive cash dividends unless and until shares of common stock are issued in settlement of such awards. However, the administrator may grant RSUs that entitle their holders to dividend equivalent rights.

•Performance awards. Performance awards, consisting of either performance shares or performance units, are awards that will result in a payment to their holder only if specified performance goals are achieved during a specified performance period. The administrator establishes the applicable performance goals based on one or more measures of business performance, such as revenue, gross margin, net income or total stockholder return. To the extent earned, performance awards may be settled in cash, in shares of our common stock or a combination of both in the discretion of the administrator. Holders of performance shares or performance units have no voting rights or rights to receive cash dividends unless and until shares of common stock are issued in settlement of such awards. However, the administrator may grant performance shares that entitle their holders to dividend equivalent rights.

•Cash-based awards and other share-based awards. The administrator may grant cash-based awards that specify a monetary payment or range of payments or other share-based awards that specify a number or range of shares or units that, in either case, are subject to vesting or other conditions specified by the administrator. Settlement of these awards may be in cash or shares of our common stock, as determined by the administrator. Their holders will have no voting rights or right to receive cash dividends unless and until shares of our common stock are issued pursuant to the awards. The administrator may grant dividend equivalent rights with respect to other share-based awards.

In the event of a change in control as described in the 2021 Plan, the acquiring or successor entity may assume or continue all or any awards outstanding under the 2021 Plan or substitute substantially equivalent awards. The compensation committee may provide for the acceleration of vesting of any or all outstanding awards upon such terms and to such extent as it determines, except that the vesting of all awards held by members of the board of directors who are not employees will automatically be accelerated in full. Any awards that are not assumed, continued, or substituted for in connection with a change in control or are not exercised or settled prior to the change in control will terminate effective as of the time of the change in control. The 2021 Plan also authorizes the compensation committee, in its discretion and without the consent of any participant, to cancel each or any outstanding award denominated in shares upon a change in control in exchange for a payment to the participant with respect to each share subject to the cancelled award of an amount equal to the excess of the consideration to be paid per share of common stock in the change in control transaction over the exercise price per share, if any, under the award.

The 2021 Plan will continue in effect until it is terminated by our compensation committee, provided, however, that all awards will be granted, if at all, within ten years of its effective date. The compensation committee may amend, suspend or terminate the 2021 Plan at any time, provided that without stockholder approval, the plan cannot be amended to increase the number of shares authorized, change the class of persons eligible to receive incentive stock options, or effect any other change that would require stockholder approval under any applicable law or listing rule.

2014 Stock Option Plan

Our 2014 Stock Option Plan (the “2014 Plan”), was originally adopted by our board of directors and approved by our stockholders in June 2014. As of December 31, 2024, we had options to purchase 5,530,529 shares of common stock outstanding under our 2014 Plan. In connection with the closing of our IPO, our board of directors terminated the 2014 Plan

and will not grant any further awards under such plan, but the 2014 Plan will continue to govern outstanding awards granted thereunder. Our compensation committee administers the 2014 Plan and has the authority, among other things, to construe and interpret the terms of the 2014 Plan and awards granted thereunder.

Timing of Equity Awards

Our insider trading policy provides that option awards granted under our equity compensation plans must generally be granted (a) during open trading windows, and (b) more than four business days before, and more than one business day after, our release of earnings for the most recently completed fiscal period or filing with the SEC. The release of MNPI may not be timed or otherwise manipulated with the intent of affecting the value of an equity award.

401(k) Plan

We maintain a retirement savings plan (“401(k) Plan”), for the benefit of our eligible employees, including our named executive officers. Our 401(k) Plan is intended to qualify under Sections 401 of the Internal Revenue Code. Each participant in the 401(k) Plan may contribute up to the statutory limit of his or her pre-tax compensation. In addition, we can make discretionary matching contributions. All salary deferrals, rollovers and matching contributions are 100% vested when contributed. The 401(k) Plan provides for automatic salary deferrals of 3% of compensation with a 1% escalator each year. Participants are permitted to waive the automatic deferral provision.

PROPOSAL 2

RATIFICATION OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Our audit committee has appointed KPMG LLP to serve as our independent registered public accounting firm for our fiscal year ending December 31, 2025. KPMG LLP served as our independent registered public accounting firm for our fiscal year ended December 31, 2024.

Notwithstanding the appointment of KPMG LLP, and even if our stockholders ratify their appointment, our audit committee, in its discretion, may appoint another independent registered public accounting firm at any time during our fiscal year if our audit committee believes that such a change would be in the best interests of our Company and our stockholders. At the Annual Meeting, our stockholders are being asked to ratify the appointment of KPMG LLP as our independent registered public accounting firm for our fiscal year ending December 31, 2025. Our board of directors is submitting the appointment of KPMG LLP 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 our stockholders do not ratify the appointment of KPMG LLP, our audit committee may reconsider the appointment or may continue to retain KPMG LLP for 2025. Representatives of KPMG LLP are expected to be present at the Annual Meeting, and they will have an opportunity to make a statement and are expected to be available to respond to appropriate questions from our stockholders.

OTHER MATTERS

Delinquent Section 16(a) Reports

Section 16(a) of the Exchange Act requires our executive officers, directors and persons who own more than ten percent of a registered class of our equity securities to file reports of ownership and changes in ownership with the SEC. Executive officers, directors and greater than ten-percent stockholders are required by SEC regulation to furnish us with copies of all Section 16(a) forms they file.

Based solely on our review of the copies of such forms furnished to us and the written representations from certain of the reporting persons that no other reports were required during the fiscal year ended December 31, 2024, all executive officers, directors and greater than ten-percent beneficial owners complied with the reporting requirements of Section 16(a).

Stockholder Proposals and Nominations

Stockholders who intend to have a proposal considered for inclusion in our proxy materials for presentation at our 2026 Annual Meeting pursuant to Rule 14a-8 under the Exchange Act must submit the proposal to our Secretary at our offices at 50 Beale Street, 8th Floor, San Francisco, California 94015 not later than December 30, 2025

Stockholders intending to present a proposal at the 2026 Annual Meeting, but not to include the proposal in our proxy statement, or to nominate a person for election as a director, must comply with the requirements set forth in our Bylaws. Our Bylaws require, among other things, that our Secretary receive written notice from the stockholder of record of their intent to present such proposal or nomination not less than 90 days nor more than 120 days prior to the first anniversary of the preceding year’s annual meeting. Therefore, we must receive notice of such a proposal or nomination for the 2026 Annual Meeting no earlier than the close of business on February 20, 2026 and no later than the close of business on March 22, 2026. The notice must contain the information required by the Bylaws, a copy of which is available upon request to our Secretary as well as on EDGAR. In the event that the date of our 2025 Annual Meeting of Stockholders is more than 30 days before or more than 30 days after June 20, 2026, then our Secretary must receive such written notice not later than the close of business on the 90th day prior to the 2026 Annual Meeting or, if later, the 10th day following the day on which public disclosure of the date of such annual meeting is first made by us. SEC rules permit management to vote proxies in its discretion in certain cases if the stockholder does not comply with this deadline and, in certain other cases notwithstanding the stockholder's compliance with this deadline. We reserve the right to reject, rule out of order, or take other appropriate action with respect to any proposal that does not comply with these or other applicable requirements.

In addition to satisfying the foregoing requirements, to comply with the universal proxy rules, stockholders who intend to solicit proxies in support of director nominees other than the Company’s nominees in connection with our 2026 Annual Meeting must provide notice that sets forth the information required by Rule14a-19 under the Exchange Act no later than April 21, 2026

Householding of Proxy Materials

The SEC has adopted rules that permit companies and brokers to satisfy the delivery requirements for proxy statements and annual reports with respect to two or more stockholders sharing the same address by delivering a single proxy statement addressed to those stockholders. This process, which is commonly referred to as “householding,” potentially means extra convenience for stockholders and cost savings for companies.

This year, a number of brokers with account holders who are our stockholders will be householding our proxy materials. A single proxy statement will be delivered to multiple stockholders sharing an address unless contrary instructions have been received from the affected stockholders. Once you have received notice from your broker that it will be householding communications to your address, householding will continue until you are notified otherwise or until you revoke your consent. If, at any time, you no longer wish to participate in householding and would prefer to receive a separate proxy statement and annual report, please (1) notify your broker, (2) direct your written request to: 50 Beale Street, 8th Floor, San Francisco, California 94015, or (3) request from the Company by calling (415) 369-8000. Stockholders who currently receive multiple copies of the proxy statement at their address and would like to request householding of their communications should contact their broker.

Other Business

As of the date of this proxy statement, the board of directors knows of no business, other than that described in this proxy statement, that will be presented for consideration at the 2025 Annual Meeting. If any other business comes before the 2025 Annual Meeting or any adjournment or postponement thereof, proxy holders may vote their respective proxies at their discretion.
