Questions and Answers about these Proxy Materials and Voting

WHY DID I RECEIVE A NOTICE REGARDING THE AVAILABILITY OF PROXY MATERIALS ON THE INTERNET?

Pursuant to rules adopted by the Securities and Exchange Commission (the “SEC”), we have elected to provide access to our proxy materials on the internet. Accordingly, we have sent you a Notice of Internet Availability of Proxy Materials (the “Notice”) because our board of directors (the “Board” or “Board of Directors”) is soliciting your proxy to vote at the 2026 Annual Meeting of Stockholders, including at any adjournments or postponements of the meeting. 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. Instructions on how to access the proxy materials over the internet or to request a printed copy may be found in the Notice.

We intend to first mail this Notice and make our proxy materials available to stockholders on or about April 21, 2026.

HOW DO I ATTEND THE ANNUAL MEETING?

The Annual Meeting will be held on Thursday, June 4, 2026 at 8:00 a.m. Pacific Time by live webcast. There will not be a physical meeting location and you will not be able to attend the meeting in-person physically. We invite you to attend the Annual Meeting by live webcast. Online check-in will begin approximately 15 minutes prior to the start of the Annual Meeting. We encourage our stockholders to enter the meeting in advance of the designated start time to have ample time for check-in procedures. To attend the Annual Meeting virtually via the internet, please visit www.virtualshareholdermeeting.com/SIBN2026 and use the 16-digit control number provided on your proxy card or voting instruction card you receive in order to be above to submit your questions and vote your shares. Therefore, it is important to retain a copy of your proxy card or voting instruction card you receive to enable you to gain participation access to the Annual Meeting.

Stockholder of Record: Shares Registered in Your Name

If on April 6, 2026, your shares are registered directly in your name with our transfer agent, Equiniti Trust Company, LLC, then you are a stockholder of record.

Beneficial Owner: Shares Registered in the Name of a Broker or Bank

If on April 6, 2026, your shares are held, not in your name, but rather in an account at a brokerage firm, bank or other similar organization, then you are the beneficial owner of shares held in “street name” and the Notice is being forwarded to you by that organization. The organization holding your account is considered to be 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 stockholder of record regarding how to vote the shares in your account. You are also invited to attend the Annual Meeting. Many stockholders of record will provide you with a 16-digit control number via email or in a voting instruction form with the Notice in order to attend, submit your questions and vote your shares at the Annual Meeting. If you did not receive a 16-digit control number via email or on the Notice or voting instruction form, you will be provided with other instructions from your broker, bank or other stockholder of record that must be followed, including any requirement to obtain a valid legal proxy, in order for your broker, bank or other stockholder of record to vote your shares per your instructions or to attend and vote your shares at the Annual Meeting. Many brokers, banks or other stockholders of record allow a stockholder to obtain a valid legal proxy either online or by mail, and we recommend that you contact your broker, bank or other stockholder of record to do so.

WHO CAN ASK QUESTIONS AT THE ANNUAL MEETING?

If you are attending the Annual Meeting as a stockholder of record or as a beneficial owner, questions can be submitted by accessing the meeting center at www.virtualshareholdermeeting.com/SIBN2026, entering your 16-digit control number and following the instructions.

If I AM A STOCKHOLDER OF RECORD AND I DO NOT VOTE, OR IF I RETURN A PROXY CARD OR OTHERWISE VOTE WITHOUT GIVING SPECIFIC VOTING INSTRUCTIONS, WHAT HAPPENS?

If you are a stockholder of record and do not vote by completing your proxy card, by telephone, through the internet or via webcast at the Annual Meeting, your shares will not be voted.

If any other matter is properly presented at the meeting, your proxy holder (one of the individuals named on your proxy card) will vote your shares using his or her best judgment.


SI-BONE, Inc.			3			2026 Proxy Statement

IF I AM A BENEFICIAL OWNER OF SHARES HELD IN STREET NAME AND I DO NOT PROVIDE MY BROKER OR BANK WITH VOTING INSTRUCTIONS, WHAT HAPPENS?

If you are a beneficial owner of shares held in street name and you do not instruct your broker, bank or other stockholder of record how to vote your shares, your broker, bank or other stockholder of record may still be able to vote your shares in its discretion. In this regard, under the rules of the New York Stock Exchange (“NYSE”), which are also applicable to Nasdaq-listed companies, brokers, banks and other securities intermediaries may use their discretion to vote your “uninstructed” shares with respect to matters considered to be “routine” under NYSE rules, but not with respect to “non-routine” matters. In this regard, Proposals Nos. 1 and 3 are considered to be “non-routine” under NYSE rules meaning that your broker may not vote your shares on those proposals in the absence of your voting instructions. However, Proposal No. 2 is considered to be a “routine” matter under NYSE rules meaning that if you do not return voting instructions to your broker by its deadline, your shares may be voted by your broker in its discretion on Proposal No. 2.

WHO IS THIS PROXY SOLICITATION MADE BY?

Your proxy is being solicited on behalf of the Board for use at the Annual Meeting.

WHO IS PAYING FOR THIS PROXY SOLICITATION?

We will pay for the entire cost of soliciting proxies. In addition to these proxy materials, our directors and employees may also solicit proxies in person, by telephone, or by other means of communication. Directors and employees will not be paid any additional compensation for soliciting proxies. We may also reimburse brokerage firms, banks and other stockholders of record for the cost of forwarding proxy materials to beneficial owners.

WHAT DOES IT MEAN IF I RECEIVE MORE THAN ONE NOTICE?

If you receive more than one Notice, your shares may be registered in more than one name or in different accounts. Please follow the voting instructions on the Notices to ensure that all of your shares are voted.

CAN I CHANGE MY VOTE AFTER SUBMITTING MY PROXY?

Stockholder of Record: Shares Registered in Your Name

Yes. You can revoke your proxy at any time before the final vote at the meeting. If you are the record holder of your shares, you may revoke your proxy in any one of the following ways:

•You may submit another properly completed proxy card with a later date.

•You may grant a subsequent proxy by telephone or through the internet.

•You may send a timely written notice that you are revoking your proxy to SI-BONE, Inc., Attn: Secretary and Chief Business & Legal Affairs Officer, at 471 El Camino Real, Suite 101, Santa Clara, California 95050.

•You may attend the Annual Meeting and vote via webcast. Simply attending the meeting will not, by itself, revoke your proxy.

Unless you vote via webcast, your most current proxy card or telephone or internet proxy is the one that is counted.

Beneficial Owner: Shares Registered in the Name of Broker or Bank

If your shares are held by your broker, bank or other stockholder of record, you should follow the instructions provided by your broker, bank or other stockholder of record regarding how to change or revoke your proxy. Simply attending the meeting will not, by itself, revoke your proxy.

WHEN ARE STOCKHOLDER PROPOSALS DUE FOR NEXT YEAR’S ANNUAL MEETING?

To be considered for inclusion in next year’s proxy materials, your proposal must be submitted in writing and received by our Secretary no later than December 22, 2026. All such proposals should be addressed to SI-BONE, Inc., Attn: Chief Business & Legal Affairs Officer, at 471 El Camino Real, Suite 101, Santa Clara, California 95050, or if sent after July 1, 2026, at 88 W Plumeria Dr, San Jose, California 95131. However, if the 2027 annual meeting of stockholders is held before May 5, 2027 or after July 4, 2027, then your proposal must be submitted in writing and received by our Secretary a reasonable time before we begin to print and send our proxy materials.


SI-BONE, Inc.			4			2026 Proxy Statement

If you wish to submit a proposal (including a director nomination) at the meeting that is not to be included in next year’s proxy materials, your proposal must be submitted in writing and received by our Secretary no earlier than the close of business on February 4, 2027 and no later than the close of business on March 6, 2027. All such proposals should be addressed to SI-BONE, Inc., Attn: Chief Business & Legal Affairs Officer, at 88 W Plumeria Dr, San Jose, California 95131. However, if the 2027 annual meeting of stockholders is held before May 5, 2027, or after July 4, 2027, then your proposal must be submitted in writing and received by our Secretary no earlier than the close of business on the one hundred twentieth (120th) day prior to such annual meeting and not later than the close of business on the later of the ninetieth (90th) day prior to such annual meeting or the tenth (10th) day following the day on which public announcement of the date of such meeting is first made.

In addition, to comply with the universal proxy rules, stockholders who intend to solicit proxies in support of director nominees other than our nominees must provide notice that sets forth the information required by Rule 14a-19 under the Exchange Act no later than April 5, 2027. However, if the 2027 annual meeting of the stockholders is held before May 5, 2027, or after July 4, 2027, for your notice to be timely, it must be so received by our Secretary by the later of sixty (60) days prior to such annual meeting or the tenth (10th) day following the day on which public announcement of the date of such annual meeting is first made.

Stockholders wishing to make stockholder proposals or nominations for directors should consult our bylaws and Rule 14a-19 under the Exchange Act, which contain additional requirements and information regarding these matters.

HOW ARE VOTES COUNTED?

Votes will be counted by the inspector of election appointed for the meeting, who will separately count: (a) with respect to the proposal to elect directors, votes “For,” votes “Withheld,” and broker non-votes; (b) with respect to the ratification of selection by the Audit Committee of the Board of Directors of PricewaterhouseCoopers LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2026, votes “For”, votes “Against,” and abstentions; (c) with respect to the advisory approval of the compensation of our named executive officers, as disclosed in this proxy statement in accordance with SEC rules, votes “For”, votes “Against,” abstentions, and broker non-votes; and (d) for any other proposals, votes “For”, votes “Against,” abstentions and, if applicable, broker non-votes.

Abstentions will be counted towards the vote total for each of Proposals No. 2 and No. 3 and will have the same effect as “Against” votes. Broker non-votes on Proposals No. 1 and No. 3 will have no effect and will not be counted towards the vote total for any of those proposals. As Proposal No. 2 is a “routine” matter we do not expect there to be any broker non-votes, but if there are broker non-votes, they will have no effect and will not be counted towards the vote total.

WHAT ARE “BROKER NON-VOTES”?

As discussed above, when a beneficial owner of shares held in street name does not give voting instructions to his or her broker, bank or other securities intermediary holding his or her shares as to how to vote on matters deemed to be “non-routine” under NYSE rules, the broker, bank or other securities intermediary cannot vote the shares. These unvoted shares are counted as “broker non-votes.”

WHAT IS THE QUORUM REQUIREMENT?

A quorum of stockholders is necessary to hold a valid meeting. A quorum will be present if stockholders holding at least a majority of the outstanding shares entitled to vote are present at the meeting via webcast or represented by proxy.

Thus, the holders of 22,121,858 shares must be present at the meeting via webcast or represented by proxy to have a quorum.

If you are a stockholder of record your shares will be counted towards the quorum only if you submit a valid proxy (or one is submitted on your behalf by your broker, bank or other securities intermediary) or if you vote via webcast at the meeting.

If there is no quorum, the chairperson of the meeting or the holders of a majority of shares present at the meeting via webcast or represented by proxy may adjourn the meeting to another date.

HOW CAN I FIND OUT THE RESULTS OF THE VOTING AT THE ANNUAL MEETING?

Preliminary voting results will be announced at the Annual Meeting.

Proposal No. 1
Election of Directors

Our Board of Directors is divided into three classes. Each class consists, as nearly as possible, of one-third of the total number of directors, and each class has a three-year term. Vacancies on the Board of Directors may be filled only by persons elected by a majority of the remaining directors. A director elected by the Board of Directors to fill a vacancy in a class, including vacancies created by an increase in the number of directors, shall serve for the remainder of the full term of that class and until the director’s successor is duly elected and qualified.

Our Board of Directors currently has eight members. There are three directors in Class II, the term of which class expires in 2026: Jeffrey W. Dunn, John G. Freund, M.D., and Gregory K. Hinckley. Each is currently a member of our Board of Directors. Mr. Dunn and Mr. Freund have been nominated for re-election as directors at the Annual Meeting. Mr. Hinckley is not standing for re-election and will therefore step down as a director and as a member of the Compensation Committee upon the expiration of his term at the conclusion of the Annual Meeting. Mr. Hinckley’s decision not to stand for re-election is not due to any disagreement with the Company on any matter relating to the Company’s operations, policies or practices. Accordingly, the size of our Board of Directors will be reduced to seven directors effective at the close of the Annual Meeting. If elected at the Annual Meeting, each of the nominees would serve until the 2029 annual meeting and until his successor has been duly elected and qualified, or, if sooner, until the director’s death, resignation or removal. It is our policy to encourage directors and nominees for director to attend the Annual Meeting. All eight of our current directors attended our 2025 annual meeting of stockholders.

Mr. Dunn and Mr. Freund were previously elected by our stockholders.

The following table presents, for the Class II nominees for election at the Annual Meeting and our other directors who will continue in office after the Annual Meeting, their independence and position or office held, as well as their age as of April 21, 2026:

SI-BONE, Inc.			14			2026 Proxy Statement

Information Regarding the Board of Directors and Corporate Governance

FAMILY RELATIONSHIPS

There are no family relationships among the directors and executive officers.

INDEPENDENCE OF THE BOARD OF DIRECTORS

As required under the Nasdaq Global Market (“Nasdaq”) listing standards, a majority of the members of a listed company’s Board of Directors must qualify as “independent,” as affirmatively determined by the Board of Directors. The Board of Directors consults with SI-BONE’s counsel to ensure that the Board of Directors’ determinations are consistent with relevant securities and other laws and regulations regarding the definition of “independent,” including those set forth in pertinent listing standards of Nasdaq, as in effect from time to time.

Consistent with these considerations, after review of all relevant identified transactions or relationships between each director, or any of his or her family members, and SI-BONE, its senior management and its independent auditors, the Board of Directors has affirmatively determined that (i) the following current directors are independent directors within the meaning of the applicable Nasdaq listing standards: Mr. Davis, Ms. Hilleman, Mr. Hinckley (who is not standing for re-election at the Annual Meeting), Ms. Nishimura, and Mr. West, and (ii) Dr. Freund, a current director as well as a nominee for director, is an independent director within the meaning of the applicable Nasdaq listing standards. In making this determination, the Board of Directors found that none of the directors or nominees for director other than Mr. Dunn and Ms. Francis had a material or other disqualifying relationship with SI-BONE and that each of these directors is “independent” as that term is defined under the Nasdaq Global Market listing standards. Mr. Dunn is not independent given his position as our former Executive Chairperson until May 1, 2023, but he is expected to become independent on May 1, 2026. Ms. Francis is not independent given her position as our Chief Executive Officer. Accordingly, a majority of our directors are independent, as required under applicable Nasdaq listing standards.

TERM OF SERVICE OF DIRECTORS

As described in Proposal No. 1 above, our directors serve for staggered three-year terms. We believe that a classified board, with a supermajority vote of our stockholders required to amend our certificate of incorporation and bylaws and thereby change this structure and/or to take other significant stockholder actions, is in the best long-term interest of our stockholders because it improves board stability and encourages long-term planning. These governance structures are also shared among a majority of our peer companies, including within our compensation peer group described below. As our company matures, we will continue to evaluate this and other decisions we have made regarding our corporate governance structures. Members of our leadership team hold regular meetings with investors and their governance representatives to discuss their views. While some stockholders have, as a matter of general application, a preference for one-year terms for directors and a simple majority vote to amend our certificate of incorporation or bylaws, we have not generally encountered significant or specific objections to the corporate governance decisions we have made.

BOARD SKILLS AND ATTRIBUTES

The following matrix provides information regarding our current directors, including certain types of knowledge, skills, experiences and attributes possessed by one or more of our directors which our Board of Directors believes are most relevant to our business and industry, and which may vary from year to year. The matrix does not encompass all of the knowledge, skills, experiences or attributes of our directors, and the fact that a particular knowledge, skill, experience or attribute is not listed does not mean that a director does not possess it. In addition, the absence of a particular knowledge, skill, experience or attribute with respect to any director does not mean such director is unable to contribute to the decision-making process in that area. The type and degree of knowledge, skill and experience listed below may vary among our directors. Currently three of our directors (38%) are women and one of our directors (13%) represents a diverse demographic background.

BOARD LEADERSHIP STRUCTURE

Our Board of Directors is currently chaired by Mr. Dunn. Mr. Dunn served as our Executive Chairperson from April 2021, when he ceased to serve as our Chief Executive Officer, until May 2023, at which time he became non-executive Chairperson of the Board. We believe that the separation of the two roles of Chairperson of the Board and Chief Executive Officer is most beneficial in furthering SI-BONE’s ability to develop and implement strategy. In particular, in making this determination, Mr. Dunn, as our former Chief Executive Officer, will continue to have intimate knowledge of our operations, both historically and currently, which will enable him to continue to act as a bridge between management and the Board. Further, Mr. Dunn serving as Chairperson alleviates the need for Ms. Francis to take on the responsibilities of Chairperson, enabling her to focus on her responsibilities in her role as our Chief Executive Officer.

Mr. Dunn is not independent given his position as our former Executive Chairperson until May 1, 2023, and he is expected to become independent on May 1, 2026. As such, during this time, the Board of Directors believes that our stockholders have been best served by having a Lead Independent Director, who has been an integral part of our Board structure and a critical aspect of effective corporate governance. Mr. Davis has served our Lead Independent Director and will continue to serve in such role until the conclusion of the Annual Meeting. Mr. Davis has brought considerable skills and experience, as described above, to the role. Upon Mr. Dunn’s expected attainment of independence on May 1, 2026, the Board believes that the separation of the roles of the non-executive Chairperson and Chief Executive Officer, with Mr. Dunn serving as an independent Chairperson, will provide independent Board leadership, and accordingly, Mr. Davis’ Lead Independent Director role will not continue following the conclusion of the Annual Meeting.

ROLE OF THE BOARD OF DIRECTORS IN RISK OVERSIGHT

One of the key functions of our Board of Directors is to inform oversight of our risk management process. In particular, our Board is responsible for monitoring and assessing strategic risk exposure. Our executive officers are responsible for the day-to-day management of the material risks we face. Our Board of Directors administers its oversight function directly as a whole, as well as through various standing committees of our Board of Directors that address risks inherent in their respective areas of oversight. For example, our Audit Committee is responsible for overseeing the management of risks associated with our financial reporting, accounting and auditing matters and cybersecurity; our Compensation Committee oversees the


SI-BONE, Inc.			16			2026 Proxy Statement

management of risks associated with our compensation policies and programs; and our Nominating and Corporate Governance Committee oversees the management of risks associated with director independence, conflicts of interest, composition and organization of our Board of Directors, director succession planning, development of and reporting on our sustainability program, and oversight of healthcare, regulatory, and fraud and abuse compliance.

MEETINGS OF THE BOARD OF DIRECTORS

Our Board of Directors met four times during 2025. Each member of the Board of Directors attended 75% or more of the aggregate number of meetings of the Board of Directors and of the committees on which he or she served, held during the portion of the last fiscal year for which he or she was a director or committee member.

BOARD COMMITTEES AND MEETINGS

Our Board of Directors has three committees: an Audit Committee, a Compensation Committee and a Nominating and Corporate Governance Committee. The following table provides membership and meeting information during 2025 for each of the Board committees (neither Mr. Dunn nor Ms. Francis has served on any committee to date):

Following the 2026 Annual Meeting and as recommended by our Nominating and Corporate Governance Committee and approved by our Board of Directors, Mr. Dunn is expected to join the Compensation Committee as a member.

Our Board of Directors has adopted a written charter for each of the Audit Committee, the Compensation Committee, and the Nominating and Corporate Governance Committee. All of these charters are available to stockholders on SI-BONE’s website at www.si-bone.com.

Below is a description of each committee of the Board of Directors.

AUDIT COMMITTEE

Our Audit Committee currently consists of Mr. Davis, Ms. Hilleman, and Mr. West, each of whom satisfies the independence requirements under the Nasdaq Global Market listing standards and Rule 10A-3(b)(1) of the Exchange Act. The chairperson of our Audit Committee is Ms. Hilleman. Our Board has determined that each of Mr. Davis, Ms. Hilleman, and Mr. West is “audit committee financial expert” within the meaning of SEC regulations. Our Board has also determined that each member of our Audit Committee has the requisite financial expertise required under the applicable requirements of the Nasdaq Global Market. In arriving at this determination, the Board has examined each Audit Committee member’s scope of experience and the nature of their employment in the corporate finance sector.

The primary purpose of the Audit Committee is to discharge the responsibilities of our Board with respect to our accounting, financial, and other reporting and internal control practices and to oversee our independent registered public accounting firm. Specific responsibilities of our Audit Committee include, but are not limited to:

•selecting a qualified firm to serve as the independent registered public accounting firm to audit our financial statements;

•evaluating the qualifications, independence and performance of the independent registered public accounting firm;


SI-BONE, Inc.			17			2026 Proxy Statement

•determining the scope of the annual audit and the audit fee;

•reviewing our financial statements and our management’s discussion and analysis of financial condition and results of operations to be included in our annual and quarterly reports to be filed with the SEC;

•considering the adequacy of our internal controls;

•developing and overseeing procedures for employees to submit concerns anonymously about questionable accounting or audit matters;

•reviewing related party transactions;

•reviewing and discussing the adequacy and effectiveness of our accounting and financial reporting processes, and the annual audits of our financial statements;

•approving (or, as permitted, pre-approving) all audit and all permissible non-audit service to be performed by the independent registered public accounting firm;

•reviewing our guidelines and policies with respect to financial and information security risk management and the use of artificial intelligence impacting financial reporting and internal controls; and

•reviewing, at least annually, the Audit Committee charter and the committee’s performance.

Our Board reviews the Nasdaq listing standards’ definition of independence for Audit Committee members on an annual basis and has determined that all Audit Committee members are independent (as independence is currently defined in Rule 5605(c)(2)(A)(i) and (ii) of the Nasdaq listing standards).

COMPENSATION COMMITTEE

Our Compensation Committee currently consists of Mr. Davis, Mr. Hinckley, and Mr. West. The chairperson of our Compensation Committee is Mr. Davis. At the conclusion of the 2026 Annual Meeting, Mr. Hinckley will cease to serve as a member of our Compensation Committee upon the expiration of his term, and as recommended by our Nominating and Corporate Governance Committee and approved by our Board of Directors, Mr. Dunn is expected to join the Compensation Committee as a member. Our Board has determined Mr. Davis, Mr. Hinckley, and Mr. West to be independent under the Nasdaq Global Market listing standards, and a “non-employee director” as defined in Rule 16b-3 promulgated under the Exchange Act. Mr. Dunn is not independent given his position as our former Executive Chairperson until May 1, 2023, but he is expected to become independent on May 1, 2026.

The primary purpose of our Compensation Committee is to discharge the responsibilities of our Board to oversee our compensation policies, plans, and programs and to review and determine the compensation to be paid to our executive officers, directors, and other senior management, as appropriate. Specific responsibilities of our Compensation Committee include:

•reviewing and approving, or in the case of our Chief Executive Officer, recommending that our Board approves compensation of our executive officers;

•reviewing and recommending to our Board the compensation of our directors;

•reviewing and approving, or recommending that our Board approve, the terms of compensatory arrangements with our executive officers;

•administering our employee stock purchase and equity incentive plans;

•selecting independent compensation consultants and assessing whether there are any conflicts of interest with any of the committee’s compensation advisors;

•reviewing and approving, or recommending that our Board approve, incentive compensation and equity plans, severance agreements, change-of-control protections, and any other compensatory arrangements for our executive officers and other senior management, as appropriate;

•reviewing and establishing general policies relating to compensation and benefits of our employees; and

•reviewing our overall compensation philosophy.


SI-BONE, Inc.			18			2026 Proxy Statement

Compensation Committee Processes and Procedures

Typically, our Compensation Committee meets at least four times annually and with greater frequency if necessary. The agenda for each meeting is usually developed by the chairperson of the Compensation Committee, in consultation with the Chief Business & Legal Affairs Officer. The Compensation Committee meets regularly in executive session. However, from time to time, various members of management and other employees as well as outside advisors or consultants may be invited by the Compensation Committee to make presentations, to provide financial or other background information or advice or to otherwise participate in Compensation Committee meetings. The Chief Executive Officer may not participate in, or be present during, any deliberations or determinations of the Compensation Committee regarding her compensation or individual performance objectives. The charter of the Compensation Committee grants the Compensation Committee full access to all of our books, records, facilities and personnel. In addition, under the charter, the Compensation Committee has the authority to obtain, at our expense, advice and assistance from compensation consultants and internal and external legal, accounting or other advisors and other external resources that the Compensation Committee considers necessary or appropriate in the performance of its duties. The Compensation Committee has direct responsibility for the oversight of the work of any consultants or advisers engaged for the purpose of advising the Compensation Committee. In particular, the Compensation Committee has the sole authority to retain, in its sole discretion, compensation consultants to assist in its evaluation of executive and director compensation, including the authority to approve the consultant’s reasonable fees and other retention terms. Under the charter, the Compensation Committee may select, or receive advice from, a compensation consultant, legal counsel or other adviser to the Compensation Committee, other than in-house legal counsel and certain other types of advisers, only after taking into consideration six factors, prescribed by the SEC and Nasdaq, that bear upon the adviser’s independence; however, there is no requirement that any adviser be independent.

During the past fiscal year, after taking into consideration the six factors prescribed by the SEC and Nasdaq described above, the Compensation Committee engaged Compensia, Inc., a national compensation consulting firm with compensation expertise relating to technology and life science companies, as its compensation consultant. The Compensation Committee requested that Compensia:

•evaluate the efficacy of our existing compensation strategy and practices in supporting and reinforcing our long-term strategic goals;

•assist in refining our compensation strategy and in developing and implementing an executive compensation program to execute that strategy;

•benchmark our use of equity in our compensation program against equity utilization of its peers;

•review the adequacy and appropriateness of our compensation of our independent directors and recommend annual updates to our non-employee director compensation policy; and

•perform an annual independent compensation risk assessment.

As part of its engagement, the Compensation Committee requested Compensia to develop a comparative group of companies and to perform analyses of competitive performance and compensation levels for that group. Compensia also conducted individual interviews with members of the Compensation Committee and senior management to learn more about our business operations and strategy, key performance metrics and strategic goals, as well as the labor markets in which we compete. Compensia ultimately developed recommendations that were presented to the Compensation Committee for its consideration. Following an active dialogue with Compensia, the Compensation Committee approved the recommendations of Compensia.

Historically, the Compensation Committee has made most of the significant adjustments to annual compensation, determined bonus and equity awards and established new performance objectives over the course of several meetings held during the fourth quarter of the preceding year and the first quarter of the year. However, the Compensation Committee also considers matters related to individual compensation, such as compensation for new executive hires, as well as high-level strategic issues, such as the efficacy of our compensation strategy, potential modifications to that strategy and new trends, plans or approaches to compensation, at various meetings throughout the year. Generally, the Compensation Committee’s process comprises two related elements: the determination of compensation levels and the establishment of the Company’s performance objectives for the current year. For executives other than the Chief Executive Officer, the Compensation Committee solicits and considers evaluations and recommendations submitted to the Compensation Committee by the Chief Executive Officer. In the case of the Chief Executive Officer, the Board conducts the evaluation of her performance, which determines any adjustments to her compensation as well as awards to be granted. For all executives and directors as part of its deliberations, the Compensation Committee may review and consider, as appropriate, materials such as financial reports and projections, operational data, tax and accounting information, tally sheets that set forth the total compensation that may become payable to executives in various hypothetical scenarios, executive and director stock ownership information, company stock performance data, analyses of historical executive compensation levels and current Company-wide compensation levels


SI-BONE, Inc.			19			2026 Proxy Statement

and recommendations of the Compensation Committee’s compensation consultant, including analyses of executive and director compensation paid at other companies identified by the consultant.

Compensation Committee Interlocks and Insider Participation

During the fiscal year ended December 31, 2025, our Compensation Committee consisted of Mr. Davis, Mr. Hinckley, and Mr. West. None of the members of our Compensation Committee is currently or has been at any time one of our officers or employees. During the fiscal year ended December 31, 2025, none of our executive officers served on the board of directors or compensation committee of any other company that has an executive officer serving on our Board of Directors or our Compensation Committee.

NOMINATING AND CORPORATE GOVERNANCE COMMITTEE

Our Nominating and Corporate Governance Committee currently consists of Dr. Freund, Ms. Hilleman, and Ms. Nishimura. The chairperson of our Nominating and Corporate Governance Committee is Ms. Nishimura. Our Board of Directors has determined Dr. Freund, Ms. Hilleman, and Ms. Nishimura each to be independent under the Nasdaq Global Market listing standards.

Specific responsibilities of our Nominating and Corporate Governance Committee include:

•identifying, evaluating, and selecting, or recommending that our Board approve, nominees for election to our Board;

•overseeing the process of evaluating the performance of our Board of Directors;

•reviewing developments in corporate governance practices;

•evaluating the adequacy of our corporate governance practices and reporting;

•developing and making recommendations to our Board regarding corporate governance guidelines and matters; and

•overseeing administration of our healthcare compliance program.

The Nominating and Corporate Governance Committee believes that director candidates should have certain minimum qualifications, including the ability to read and understand basic financial statements, being over 21 years of age and having the highest personal integrity and ethics. The Nominating and Corporate Governance Committee also intends to consider such factors as possessing relevant expertise upon which to be able to offer advice and guidance to management, having sufficient time to devote to our affairs, having demonstrated excellence in his or her field, having the ability to exercise sound business judgment and having the commitment to rigorously represent the long-term interests of our stockholders. However, the Nominating and Corporate Governance Committee retains the right to modify these qualifications from time to time. Potential director candidates are reviewed in the context of the current composition of the Board, our operating requirements and the long-term interests of our stockholders. In conducting this assessment, the Nominating and Corporate Governance Committee considers diversity of skills, experience, personal background, perspective and such other factors as it deems appropriate, given the current needs of the Board and the Company, to maintain a balance of knowledge, experience and capability.

The Nominating and Corporate Governance Committee appreciates the value of thoughtful Board refreshment, and regularly identifies and considers qualities, skills and other director attributes that would enhance the composition of the Board. In the case of incumbent directors whose terms of office are set to expire, the Committee reviews these directors’ overall service to the Company during their terms, including the number of meetings attended, level of participation, quality of performance and any other relationships and transactions that might impair the directors’ independence. In the case of potential director candidates, the Nominating and Corporate Governance Committee also determines whether they are independent based upon applicable Nasdaq listing standards, applicable SEC rules and regulations and the advice of counsel, if necessary. The Nominating and Corporate Governance Committee then uses its network of contacts to compile a list of potential director candidates, but may also engage, if it deems appropriate, a professional search firm. The Nominating and Corporate Governance Committee conducts any appropriate and necessary inquiries into the backgrounds and qualifications of potential director candidates after considering the function and needs of the Board. The Nominating and Corporate Governance Committee meets to discuss and consider the potential director candidates’ qualifications and then selects a candidate for recommendation to the Board by majority vote.

The Nominating and Corporate Governance Committee will consider director candidates recommended by stockholders. The Nominating and Corporate Governance Committee does not intend to alter the manner in which it evaluates director candidates, including the minimum criteria set forth above, based on whether or not the director candidate was recommended by a stockholder. Stockholders who wish to recommend individuals for consideration by the Nominating and Corporate Governance Committee to become nominees for election to the Board may do so by delivering a written recommendation to

We believe our responsiveness to stockholder communications with our directors has been excellent. Stockholders may communicate with the Board or any of our directors.

We have a whistleblower hotline and website where people can report violations of the Code of Business Conduct and Ethics anonymously or by name; to date we have never had a good-faith complaint alleging violations of our Code of Conduct come into the hotline.

CORPORATE GOVERNANCE GUIDELINES

In July 2018, the Board of Directors adopted, and in January 2021, December 2022, June 2023, June 2025 and December 2025 revised, our Corporate Governance Guidelines to assure that the Board has the necessary authority and policies in place to review and evaluate our business operations as needed and to make decisions that are independent of our management. The guidelines are also intended to align the interests of directors and management with those of our stockholders. The Corporate Governance Guidelines set forth the practices the Board intends to follow with respect to board composition and selection including qualifications, board meetings and involvement of senior management, Chief Executive Officer performance evaluation and succession planning, board committees and compensation, board and committee self-assessments, and our prohibition on engaging in hedging, pledging or other inherently speculative transactions in our stock. The Corporate Governance Guidelines, as well as the charters for each committee of the Board, may be viewed at www.si-bone.com.

INSIDER TRADING POLICY

We have adopted an Insider Trading Policy governing the purchase, sale, and/or other dispositions of our securities by directors, officers, and employees that is designed to promote compliance with insider trading laws, rules, and regulations, as well as procedures designed to further the foregoing purposes. From time to time, we may engage in transactions in our securities. It is our policy to comply with applicable laws and regulations relating to insider trading. A copy of our insider trading policy is filed as an exhibit to our Annual Report on Form 10-K for our fiscal year ended December 31, 2025.

As set forth in our Insider Trading Policy and Corporate Governance Guidelines, no director, employee or consultant may engage in short sales, transactions in put or call options, hedging transactions, margin accounts, pledges, or other inherently speculative transactions with respect to our stock at any time.

STOCK OWNERSHIP GUIDELINES

In December 2020, the Board of Directors adopted stock ownership guidelines applicable to each of our directors and executive officers. Pursuant to these guidelines, our Chief Executive Officer is expected to own shares of our common stock with a value of at least three times his or her annual base pay, each of our executive officers other than our Chief Executive Officer is expected to own shares of our common stock with a value of at least his or her annual base salary, and each of our directors is expected to own shares of our common stock with a value of at least three times our annual retainer for independent directors for service on the Board of Directors. The guidelines provide that the applicable person has five years from the later of the adoption of this policy and the time the person becomes subject to this policy to achieve their applicable stock ownership.

CYBERSECURITY

We recognize the importance of protecting our information technology (“IT”) systems. With this in mind, we have certain IT and cybersecurity measures on both an enterprise level and on an individual employee level. We have in place various types and levels of IT and cybersecurity measures, depending on the nature of the IT system and data, which are aimed at protecting IT systems to help secure long-term value for our stockholders and other stakeholders. By way of example, these measures may include the following:

•utilization of detection and protection technologies such as endpoint detection and vulnerability and patch management programs;

•ongoing end-user security awareness training;

•security metric reporting to senior organizational leaders; and

•periodic risk assessments and maturity assessments to gauge current level of operational efficiency and effectiveness.

Our Audit Committee and senior management are responsible for overseeing matters relating to our IT and cybersecurity practices and initiatives, and our Audit Committee is briefed at least quarterly by our senior management on cybersecurity matters. To assist our senior management and Audit Committee, we have designated specific roles for officers and other employees within our company who are responsible for and directly oversee our IT and cybersecurity measures. Among the members of our Board of Directors, two served as Chief Financial Officers having direct oversight of Information Technology / Cybersecurity functions, developed expertise in this area, and either served or still serve on the audit committees of other companies’ boards exercising cybersecurity oversight as well.

SUSTAINABILITY OVERSIGHT AND ACTIVITIES

We strive to advance the interests of all our stakeholders - including patients, healthcare professionals, employees, investors, and our communities - by operating in an ethical and sustainable way. We do this by holding true to our core values of operating with Purpose, Agility and Creativity, and as a single Team. These values are at the heart of our sustainability activities.

Proposal No. 2
Ratification of Selection of Independent Registered Public Accounting Firm

The Audit Committee of the Board of Directors has selected PricewaterhouseCoopers LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2026, and has further directed that management submit the selection of PricewaterhouseCoopers LLP as our independent registered public accounting firm for ratification by the stockholders at the Annual Meeting. PricewaterhouseCoopers LLP has audited our financial statements since our inception in 2008. Representatives of PricewaterhouseCoopers LLP are expected to be present at the Annual Meeting. They will have an opportunity to make a statement if they so desire and will be available to respond to appropriate questions.

Neither our bylaws or other governing documents nor law require stockholder ratification of the selection of PricewaterhouseCoopers LLP as our independent registered public accounting firm. However, the Audit Committee of the Board is submitting the selection of PricewaterhouseCoopers LLP to the stockholders for ratification as a matter of good corporate practice. If the stockholders fail to ratify the selection, the Audit Committee of the Board will reconsider whether or not to retain PricewaterhouseCoopers LLP. Even if the selection is ratified, the Audit Committee of the Board in its discretion may direct the appointment of different independent auditors at any time during the year if they determine that such a change would be in the best interests of the Company and its stockholders.


The Board of Directors recommends a vote IN FAVOR of Proposal No. 2.

PRINCIPAL ACCOUNTANT FEES AND SERVICES

The following table represents aggregate fees billed to the Company for the fiscal years ended December 31, 2025 and 2024, respectively, by PricewaterhouseCoopers LLP, our independent registered public accounting firm.

•Audit Fees consist of fees incurred for professional services rendered for the audit of our annual consolidated financial statements, review of our quarterly consolidated financial statements, and other services normally provided by PricewaterhouseCoopers LLP in connection with regulatory filings.

•Tax Fees consist of fees for professional services for tax compliance, tax advice and tax planning.

•All Other Fees consist of fees for professional services other than the services reported above, including permissible consulting services.

All fees described above were pre-approved by the Audit Committee.

PRE-APPROVAL POLICIES AND PROCEDURES

Our Audit Committee has adopted a policy and procedures for the pre-approval of audit and non-audit services rendered by our independent registered public accounting firm, PricewaterhouseCoopers LLP. The policy generally pre-approves specified services in the defined categories of audit services, audit-related services and tax services up to specified amounts. We also maintain a small standing authority for management to direct pre-approved fees, the uses of which are reviewed by the Audit Committee and the pre-approved amount of which is replenished as necessary at each meeting of the Audit Committee. Pre-approval may also be given as part of the Audit Committee’s approval of the scope of the engagement of the independent auditor or on an individual, explicit, case-by-case basis before the independent auditor is engaged to provide each service. The pre-approval of services may be delegated to one or more of the Audit Committee’s members, but the decision must be reported to the full Audit Committee at its next scheduled meeting.

The Audit Committee has determined that the rendering of services other than audit services by PricewaterhouseCoopers LLP is compatible with maintaining the principal accountant’s independence.

Report of the Audit Committee of the Board of Directors

Our Audit Committee has reviewed and discussed the audited financial statements for the fiscal year ended December 31, 2025 with our management. The Audit Committee has discussed with the independent registered public accounting firm the matters required to be discussed by the applicable requirements of the Public Company Accounting Oversight Board (“PCAOB”) and the Securities and Exchange Commission. The Audit Committee has also received the written disclosures and the letter from the independent registered public accounting firm required by applicable requirements of the PCAOB regarding the independent accountants’ communications with the Audit Committee concerning independence and has discussed with the independent registered public accounting firm its independence. Based on the foregoing, the Audit Committee has recommended to the Board of Directors that the audited financial statements be included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2025.

Proposal No. 3
Advisory, Non-Binding Vote on Executive Compensation

Under the Dodd-Frank Wall Street Reform and Consumer Protection Act, or the Dodd-Frank Act, and Section 14A of the Exchange Act, our stockholders are entitled to vote to approve, on an advisory basis, the compensation of our named executive officers as disclosed in this proxy statement in accordance with SEC rules.

This vote is not intended to address any specific item of compensation, but rather the overall compensation of our named executive officers and the philosophy, policies and practices described in this proxy statement. The compensation of our named executive officers subject to the vote is disclosed in the compensation tables and the related narrative disclosure contained in this proxy statement. As discussed in those disclosures, we believe that our compensation policies and decisions are focused on pay-for-performance principles and strongly aligned with our stockholders’ interests, consistent with current market practices. Compensation of our named executive officers is designed to enable us to attract and retain talented and experienced executives to lead our company successfully in a competitive environment. Please see the Compensation Discussion & Analysis for a description of our compensation policies and decisions.

Accordingly, the Board is asking our stockholders to indicate their support for the compensation of our named executive officers as described in this proxy statement by casting a non-binding advisory vote “FOR” the following resolution:

“RESOLVED, that the compensation paid to our named executive officers, as disclosed pursuant to Item 402 of Regulation S-K, including the compensation tables and narrative discussion, is hereby APPROVED.”

Because the vote is advisory, it is not binding on the Board of Directors or us. Nevertheless, the views expressed by our stockholders, whether through this vote or otherwise, are important to management and the Board and, accordingly, the Board and the Compensation Committee intend to consider the results of this vote in making determinations in the future regarding executive compensation arrangements.

Unless the Board decides to modify its policy regarding the frequency of soliciting advisory votes on the compensation of our named executives, the next scheduled say-on-pay vote will be at the 2027 Annual Meeting of Stockholders.


The Board of Directors recommends a vote IN FAVOR of Proposal No. 3.

Executive Compensation

COMPENSATION DISCUSSION & ANALYSIS

This material is intended to assist our stockholders in understanding our executive compensation program by providing an overview of our executive compensation-related policies, practices, and decisions for fiscal 2025. It also explains how we determined the material elements of compensation for our principal executive officer and our other two executive officers as of the end of fiscal 2025, and who we refer to as our “Named Executive Officers.” For 2025, our Named Executive Officers were:

•Laura A. Francis, our Chief Executive Officer (our “CEO”);

•Anshul Maheshwari, our Chief Operating Officer & Chief Financial Officer;

•Michael A. Pisetsky, our Chief Business & Legal Affairs Officer; and

•Anthony J. Recupero, our former President, Commercial Operations.

Effective February 15, 2026, Mr. Recupero retired and was succeeded by Nikolas Kerr as Chief Commercial Officer.

We provide an overview of our executive compensation philosophy, the overall objectives of our executive compensation program, and each compensation element that we provide to our Named Executive Officers. In addition, we explain how and why the Compensation Committee of our Board of Directors (the “Compensation Committee”) and, in the case of our Chief Executive Officer, our Board of Directors after receiving the recommendation of our Compensation Committee, arrived at the specific compensation decisions for our Named Executive Officers in 2025.

OVERVIEW

We are a leader in developing innovative procedural solutions for compromised bone, grounded in expertise in biomechanical design and anatomy-specific innovation. As pioneers of minimally invasive treatment for sacroiliac joint dysfunction and degeneration, we have developed a deep competency in addressing the challenges of low-density bone in the sacrum. With our additive manufacturing, or 3D-printing, experience developed in sacroiliac fusion, we have established a technology platform that now extends to meet critical unmet needs in thoracolumbar fixation and fusion and pelvic trauma. Our products include a series of patented titanium implants, and the instruments used to implant them, as well as implantable bone products. Since launching our first generation iFuse in 2009, we have launched multiple implant product lines, including iFuse-3D in 2017, iFuse TORQ in 2021, iFuse Bedrock Granite in 2022, and iFuse INTRA and iFuse TORQ TNT in 2024. In the United States, iFuse, iFuse-3D, iFuse TORQ and iFuse Bedrock Granite have clearances for applications in sacroiliac joint dysfunction, adult spinal deformity and pelvic trauma. iFuse TORQ TNT has clearances for applications in pelvic trauma and sacroiliac joint dysfunction. We market our products primarily with a direct sales force as well as a number of third-party sales agents in the United States, and with a combination of a direct sales force, and sales agents and resellers in other countries.

2025 Business Highlights

2025 was a strong year for us in many critical areas of performance, including continued revenue growth, record growth in our active surgeon base and improving operating leverage.

•Achieved worldwide revenue of $200.9 million, representing an annual increase of ~20%;

•Over 2,400 U.S. physicians performed nearly 22,000 procedures;

•Surpassed 140,000 procedures performed by physicians worldwide since inception;

•Net loss of $18.9 million, representing an annual improvement of ~39%;

2025 Executive Compensation Highlights

Our approach to executive compensation in 2025 reflected our measured approach to attracting, retaining, and incentivizing key members of our management team, and aligning their interests with our stockholders. Our overall compensation program consists of three components: base salary, annual cash incentive bonus, and long-term equity incentive compensation. Following are highlights of key compensation actions that were taken with respect to our Named Executive Officers for 2025:

•Base Salaries. At the beginning of 2025, after considering our compensation philosophy and the competitive market environment, we provided: Ms. Francis with a 5% increase in base salary, Mr. Maheshwari with a 4% increase in base salary, Mr. Recupero with 3% increase in base salary, and Mr. Pisetsky with 4% increase in base salary, as further described in “Base Salary” below.

•Annual Cash Bonuses. Our annual cash bonus program in 2025 was based on the achievement of financial goals – Revenue Growth and Adjusted EBITDA – and operational metrics. For 2025, our Compensation Committee made the determination to increase the annual cash incentive targets as a percentage of base salary for Ms. Francis from 90% to 100%, for Mr. Maheshwari from 55% to 60%, and for Mr. Pisetsky from 45% to 50%. No changes were made for Mr. Recupero. Based on achievement against our 2025 targets, the actual cash incentive compensation payments made to our Named Executive Officers for 2025 represented 106.5% of their target cash bonus opportunities. Details of this program appear in “Annual Cash Bonuses” below.

•Long-Term Equity Incentive Compensation. For 2025, we granted a combination of restricted stock units (“RSUs”) and performance-based restricted stock units (“PSUs”) to our Named Executive Officers. Ms. Francis’ 2025 equity grants were issued 50% as RSUs and 50% as PSUs; Messrs. Maheshwari, Recupero, and Pisetsky’s 2025 equity grants were issued 75% as RSUs and 25% as PSUs. RSU grants serve to align the interests of management and our stockholders and act as an important retention mechanism, and PSUs, which are based on a combination of financial performance metrics and SI-BONE’s total shareholder return relative to a group of industry peers, reinforce both operational execution and stockholder value creation. These programs are detailed in “Long-Term Incentive Compensation” below.

SAY-ON-PAY VOTE RESULTS

At our Annual Meeting of stockholders in June 2025, our stockholders had the opportunity to cast an annual advisory vote on the compensation of our Named Executive Officers (commonly known as a “say-on-pay” vote). Approximately 98.3% of the votes cast on the proposal approved, on an advisory basis, the compensation of our Named Executive Officers as disclosed in last year’s proxy statement. Although the vote is non-binding, our Compensation Committee considers the results of the say-on-pay vote when making compensation decisions, allowing our stockholders to provide input on our compensation philosophy, policies and practices. The Compensation Committee believes that our voting results reflect our efforts to properly align pay with performance while also aligning management and stockholder interests. We value the opinions of our stockholders, and our Compensation Committee and Board of Directors will continue to consider the outcome of future

advisory votes, including the say-on-pay vote which will take place at the Annual Meeting, when making compensation decisions for the Named Executive Officers.

Stockholder Engagement on Executive Compensation

During 2025, we reached out to holders of 73% of our outstanding common stock across 22 firms, seeking to engage with them on executive compensation and other governance topics.

We found these discussions to be extremely useful and received valuable feedback on our executive compensation program. In response to this feedback, we took the following actions:

•We increased the weight of Adjusted EBITDA goals in our compensation program by introducing financial metric-based PSUs for the CEO.

•We are continuing to exercise discipline around our equity burn rate.

We intend to continue to initiate dialogue with our stockholders on executive compensation and other governance topics. In addition, we welcome stockholder communication with the Board of Directors through the channels set forth in this proxy statement.

Pay-for-Performance Alignment

We believe our executive compensation program is reasonable and competitive, and appropriately balances the goals of attracting, motivating, and retaining a talented leadership team and appropriately rewarding them for their contributions to the business. Our 2025 executive compensation program was heavily weighted towards “at-risk” compensation:

•Cash incentive opportunities under the annual bonus plan would have value only to the extent that we achieved certain predetermined financial and operational performance goals;

•The value of the PSUs depends on our total shareholder return relative to that of a group of industry peers over one, two, and three-year performance periods and our financial performance metrics, including revenue and adjusted EBITDA.

•The value of both RSUs and PSUs depends on our operational execution and success in building and sustaining long-term shareholder value.

The following charts illustrate the target pay mix for our Chief Executive Officer and our other Named Executive Officers in 2025:

The percentages in the charts above represent the target compensation for our CEO and the average target compensation for our other Named Executive Officers for 2025.


SI-BONE, Inc.			31			2026 Proxy Statement

Governance Policies and Practices

We endeavor to maintain sound executive compensation policies and practices, including compensation-related corporate governance standards, consistent with our executive compensation philosophy. During 2025, the following executive compensation policies and practices were in place, including both policies and practices we have implemented to drive performance and policies and practices that either prohibit or minimize behaviors that we do not believe serve our stockholders’ long-term interests:

What We Do

What We Don’t Do

Actively engage in year-round dialogue with our stockholders and incorporate feedback into our compensation programs

No pension plans or Supplemental Executive Retirement Plans

Significant portion of compensation for Named Executive Officers is “at-risk” based on company performance (financial & stock price)

No hedging or pledging of our securities

Provide compensation mix that more heavily weights variable pay and long-term equity

No excise tax gross-up upon a change of control

Stock ownership requirements apply to all Named Executive Officers and non-employee directors

No significant perquisites to our Named Executive Officers

An independent compensation consultant advises the Compensation Committee

No single-trigger equity acceleration or excessive severance benefits

Annually assess the risk-reward balance of our compensation programs in order to mitigate undue risks in our programs

Maintain a fully independent Compensation Committee

Maintain a clawback policy that provides for the recoupment of incentive compensation in the case of a financial restatement

Our Board of Directors maintains a robust succession strategy

COMPENSATION PHILOSOPHY AND GUIDING PRINCIPLES

We have designed our executive compensation program to reward our Named Executive Officers at a level consistent with our overall strategic and financial performance and to provide remuneration sufficient to attract, retain, and motivate them to exert their best efforts in the highly competitive environment in which we operate. We believe that competitive compensation packages consisting of a combination of base salaries, annual cash bonus opportunities, and long-term incentive opportunities in the form of equity awards that are earned over a multi-year period enable us to attract top talent, motivate successful short-term and long-term performance, satisfy our retention objectives, and align the compensation of our executive officers with our performance and long-term value creation for our stockholders.

The Compensation Committee periodically reviews and analyzes market trends and the prevalence of various compensation delivery vehicles and adjusts the design and operation of our executive compensation program from time to time as it deems necessary and appropriate. In designing and implementing the various elements of our executive compensation program, the Compensation Committee considers market and industry practices, as well as the tax efficiency of our compensation structure and its impact on our financial condition. While the Compensation Committee considers all of the factors in its deliberations, it places no formal weighting on any one factor.

As we continue to grow, the Compensation Committee evaluates our compensation philosophy and program objectives as circumstances require. At a minimum, the Compensation Committee reviews executive compensation annually.


SI-BONE, Inc.			32			2026 Proxy Statement

COMPENSATION-SETTING PROCESS

Role of the Compensation Committee

The Compensation Committee, among its other responsibilities, establishes our overall compensation philosophy and reviews and approves our executive compensation program, including the specific compensation of our Named Executive Officers (recommends to our Board of Directors in the case of our CEO). The Compensation Committee has the authority to retain special counsel and other advisors, including compensation consultants, to assist in carrying out its responsibilities to determine the compensation of our Named Executive Officers. The Compensation Committee’s authority, duties, and responsibilities are described in its charter, which is reviewed annually and revised and updated as warranted. The charter is available on our Company website at https://investor.si-bone.com/corporate-governance/governance-highlights.

At the beginning of each year, the Compensation Committee reviews our executive compensation program, including any incentive compensation plans and arrangements, to assess whether our compensation elements, actions, and decisions (i) are properly coordinated, (ii) are aligned with our mission, vision, values, and corporate goals, (iii) provide appropriate short-term and long-term incentives for our executive officers, (iv) achieve their intended purposes, and (v) are competitive with the compensation of executives in comparable positions at our peer companies. Following this assessment, the Compensation Committee makes any necessary or appropriate modifications to our existing plans and arrangements or adopts new plans or arrangements.

The factors considered by the Compensation Committee in determining the compensation of our Named Executive Officers for 2025 (or recommending to the Board of Directors in the case of our CEO) included:

•the recommendations of our CEO (except with respect to her own compensation) as described below;

•our corporate growth and other elements of financial performance;

•our corporate achievements against one or more short-term and long-term performance objectives;

•the individual performance of each Named Executive Officer against his or her management objectives;

•a review of the relevant competitive market data and executive retention analysis as prepared by its compensation consultant (as described below);

•the expected future contribution of the individual Named Executive Officer;

•historical compensation awards we have made to our Named Executive Officers; and

•internal pay equity based on the impact on our business and performance.

The Compensation Committee did not weight these factors in any predetermined manner, nor did it apply any formulas in making its decisions. The members of the Compensation Committee considered this information in light of their individual experience, knowledge of the company, knowledge of each Named Executive Officer, knowledge of the competitive market, and business judgment.

As part of this process, the Compensation Committee also evaluates the performance of our CEO each year and makes all decisions regarding recommending to the Board of Directors her base salary adjustments, target annual cash bonus opportunities, actual cash bonus payments, and long-term incentives in the form of equity awards. Our CEO is not present during any of the deliberations regarding her compensation, and no Named Executive Officer is present during any deliberations regarding their compensation.

Role of Our CEO

Our CEO works closely with the Compensation Committee in determining the compensation of our other senior executives, including our other Named Executive Officers. Typically, our CEO works with the Compensation Committee to recommend the structure of the annual bonus plan, to identify and develop corporate performance objectives for such plan, and to evaluate actual performance against the selected measures. At the beginning of each year, our CEO reviews the performance of our other senior executives for the previous year, and then shares these evaluations with, and makes recommendations to, the Compensation Committee for each element of compensation. Using her subjective evaluation of each senior executive’s performance and taking into consideration historical compensation awards to our senior executives and our corporate performance during the preceding year, these recommendations concern base salary adjustments, target annual cash bonus opportunities, and long-term incentives in the form of equity awards for each of our senior executives (other than herself) based on our results, the individual executive’s contribution to these results, and his or her performance toward achieving his or her individual performance goals. The Compensation Committee then reviews these recommendations and considers the other factors described above and makes decisions as to the target total direct compensation of each senior executive (other than our CEO), as well as each individual compensation element.


SI-BONE, Inc.			33			2026 Proxy Statement

While the Compensation Committee considers our CEO’s recommendations, as well as the competitive market analysis prepared by its compensation consultant, these recommendations and market data serve as only two of several factors in making its decisions with respect to the compensation of our senior executives. Ultimately, the Compensation Committee applies its own business judgment and experience to determine the individual compensation elements and amount of each element for our senior executives.

Role of Compensation Consultant

Pursuant to its charter, the Compensation Committee has the authority to engage its own legal counsel and other advisors, including compensation consultants, as it determined in its sole discretion, to assist in carrying out its responsibilities. The Compensation Committee makes all determinations regarding the engagement, fees, and services of these advisors, and any such advisor reports directly to the Compensation Committee.

In 2025, pursuant to this authority, the Compensation Committee engaged Compensia, Inc., a national compensation consulting firm, to provide information, analysis, and other assistance relating to our executive compensation program on an ongoing basis. The nature and scope of the services provided to the Compensation Committee by Compensia in 2025 were as follows:

•Reviewed and updated the compensation peer group;

•Provided advice with respect to compensation best practices and market trends;

•Conducted an analysis of the levels of overall compensation and each element of compensation for our Named Executive Officers and for the members of our Board of Directors; and

•Provided ad hoc advice and support on compensation and governance topics throughout the year.

Representatives of Compensia attend meetings of the Compensation Committee as requested and communicate with the Compensation Committee outside of meetings. Compensia reports to the Compensation Committee rather than to management, although Compensia may meet with members of management, including our CEO and members of our executive compensation staff, for purposes of gathering information on proposals that management may make to the Compensation Committee. During 2025, Compensia met with various executive officers to collect data and obtain managements’ perspective on various executive compensation proposals.

The Compensation Committee may replace its compensation consultant or hire additional advisors at any time. Compensia has not provided any other services to us and has received no compensation other than with respect to the services described above.

The Compensation Committee has assessed the independence of Compensia taking into account, among other things, the various factors as set forth in Exchange Act Rule 10C-1 and the enhanced independence standards and factors set forth in the applicable listing standards of the Nasdaq Stock Market, and has concluded that its relationship with Compensia and the work of Compensia on behalf of the Compensation Committee has not raised any conflict of interest.

Competitive Positioning

Given our unique business profile, history, and market competitors, the Compensation Committee believes that the competitive market for executive talent includes primarily medical device and equipment companies and, to a lesser extent, the broader healthcare sector. Accordingly, it develops a compensation peer group to contain a carefully selected cross-section of such public companies with revenues and market capitalizations that are similar to ours, using factors described below. The Compensation Committee considers the compensation practices of these peer group companies as one factor in its compensation deliberations. This peer group data is supplemented with executive compensation survey data representing public medical device, technology, and life sciences companies that are of similar size to SI-BONE, as well as market trends and best practices in executive compensation and the judgment of the Compensation Committee members. Other important factors taken into consideration when determining executive pay levels include employee knowledge, skills and experience; individual performance; scope of responsibilities; and any retention concerns.


SI-BONE, Inc.			34			2026 Proxy Statement

2025 Compensation Peer Group

In September 2024, the Compensation Committee, with the assistance of Compensia, approved the following target criteria for determining the composition of our peer group for purposes of evaluating the compensation of our Named Executive Officers for 2025.

•Revenue: 0.4x to 2.5x our revenue

•Market capitalization: 0.25x to 4.0x our market capitalization

•Industry: medical device and equipment

•Location: public companies headquartered in the United States

Accordingly, the following 18 companies were selected by the Compensation Committee as the defined peer group for purposes of 2025 executive compensation decisions:


Alphatec Holdings, Inc.	OrthoPediatrics Corp.	Silk Road Medical, Inc.
Artivion, Inc.	Paragon 28, Inc.	STAAR Surgical Company
Axogen, Inc.	PROCEPT BioRobotics Corporation	Tactile Systems Technology, Inc.
Cerus Corporation	Pulmonx Corporation	Treace Medical Concepts, Inc.
LeMaitre Vascular, Inc.	RxSight, Inc.	Vericel Corporation
Orthofix Medical Inc.	Sight Sciences, Inc.	Zynex, Inc.

The Compensation Committee reviews the compensation peer group on an annual basis and adjusts the company composition as needed based on the current financial profile and business focus of the included companies relative to SI-BONE. As part of its process for developing our 2025 peer group, the Compensation Committee made the following changes to our 2024 peer group:

•Removed Cutera, Nevro and Glaukos due to their revenue and/or market capitalization.

•Added Artivion, Tactile Systems Technology, and Vericel based on the criteria above.

COMPENSATION ELEMENTS

The three primary elements of our executive compensation programs are: (1) base salary, (2) annual cash bonus opportunities, and (3) long-term incentives in the form of equity awards as described below:


SI-BONE, Inc.			35			2026 Proxy Statement

Compensation Element

What This Element Rewards

Purpose and Key Features of Element

Base salary

Individual performance, level of experience, expected future performance and contributions

Provides competitive level of fixed compensation determined by the market value of the position, with actual base salaries established based on the facts and circumstances of each executive officer and each individual position

Annual cash bonuses

Achievement of pre-established corporate performance objectives for 2025

Motivates executive officers to achieve or exceed our corporate and financial short-term goals that are aligned with stockholders’ interests

Long-term incentives/equity awards

Achievement of long-term performance objectives, including total stockholder return and annual financial performance (Revenue Growth and Adjusted EBITDA), as well as continued service through time-based vesting.

Annual equity awards provide a variable “at risk” pay opportunity. RSUs vest over four years and PSUs vest over three years subject to meeting established total shareholder return (“TSR”) performance criteria and certain financial metrics.

Because the ultimate value of these equity awards is directly related to the market price of our common stock, and the awards are only earned over an extended period of time subject to vesting, they serve to focus management on the creation and maintenance of long-term stockholder value

Our Named Executive Officers also participate in the standard employee benefit plans available to most of our employees. In addition, our Named Executive Officers are eligible for modest post-employment (severance and change in control) payments and benefits under certain circumstances.

Each of these compensation elements is discussed in detail below, including a description of the particular element, how it fits into our overall executive compensation program, and summary of the amounts of compensation paid to our Named Executive Officers in 2025 under each of these elements.

Base Salary

We believe that a competitive base salary is a necessary element of our executive compensation program, so that we can attract and retain a stable management team. Base salaries for our Named Executive Officers are also intended to be competitive with those received by other individuals in similar positions at the companies with which we compete for talent, as well as equitable across the executive team.

Generally, we establish the initial base salaries of our Named Executive Officers through arm’s-length negotiation at the time we hire the individual executive officer, taking into account his or her position, qualifications, experience, and the base salaries of our other executive officers.

Thereafter, the Compensation Committee reviews the base salaries of our Named Executive Officers annually and makes adjustments to base salaries (recommends to our Board of Directors in the case of our CEO) as it determines to be necessary or appropriate.

In 2025, the Compensation Committee reviewed the base salaries of our executive officers, taking into consideration a competitive market analysis performed by Compensia and the recommendations of our CEO (except with respect to her own base salary), as well as the other factors described above. Following this review, the Compensation Committee set (recommended to our Board of Directors in the case of our CEO) the base salaries of our executive officers at levels that it believed were appropriate to maintain their competitiveness.

The base salaries of our Named Executive Officers established at the beginning of 2025 were as follows:


Named Executive Officer	2024 Base Salary ($)	2025 Base Salary ($)	Percentage Adjustment (%)

Laura A. Francis	652,000	685,000	5
Anshul Maheshwari	477,565	496,668(1)	4
Anthony J. Recupero	486,000	500,580	3
Michael A. Pisetsky	474,430	493,407	4

1.Mr. Maheshwari received an additional 4.5% increase to $477,565, in August 2024 to reflect expanded responsibilities. For 2025, his base salary was increased 4% to $496,668.


SI-BONE, Inc.			36			2026 Proxy Statement

The actual base salaries earned by our Named Executive Officers during 2025 are set forth in the “2025 Summary Compensation Table” below.

Annual Cash Bonuses

We use annual bonuses to motivate our executive officers, including our Named Executive Officers, to achieve our short-term financial and operational objectives while making progress towards our longer-term growth and other goals. Consistent with our executive compensation philosophy, these annual bonuses are intended to help us deliver a competitive total direct compensation opportunity to our executive officers. Annual cash bonuses are entirely performance-based, are not guaranteed, and may vary materially from year-to-year.

Typically, the Compensation Committee establishes (recommends to our Board of Directors in the case of our CEO) cash bonus opportunities pursuant to a formal cash bonus plan that measures and rewards our executive officers for our actual corporate performance over the fiscal year. The cash bonus plan is designed to pay above-target bonuses when we exceed our annual corporate objectives and below-target bonuses (or no bonuses) when we do not achieve these objectives.

In January 2025, the Compensation Committee determined to award (recommend to our Board of Directors in the case of our CEO) cash bonus opportunities to our Named Executive Officers, pursuant to the cash bonus plan for 2025. The Compensation Committee has the authority to select the performance measures and related target levels applicable to the annual cash bonus opportunities for our executive officers. The Compensation Committee may also, in its sole discretion, increase, reduce, or eliminate a participant’s actual bonus payment.

Target Bonus Opportunities

The 2025 target annual cash bonus opportunities for each of our Named Executive Officers under the 2025 cash bonus plan, expressed as a percentage of his or her annual base salary, were as follows:


Named Executive Officer	2025 Base Salary ($)	2025 Target Bonus Percentage (%)	Total 2025 Target Bonus Opportunity ($)

Laura A. Francis	685,000	100	685,000
Anshul Maheshwari	496,668	60	298,001
Anthony J. Recupero	500,580	75	375,435
Michael A. Pisetsky	493,407	50	246,704

The target annual cash bonus opportunities of our executive officers, including the Named Executive Officers, were driven entirely by achievement of corporate financial and operational objectives. The Compensation Committee determined this allocation to be appropriate to focus our executive officers on our short-term financial objectives as reflected in our annual operating plan while, at the same time, recognizing their contributions to the achievement of these objectives and the successful execution of their individual roles and responsibilities.

Corporate Performance Objectives

For purposes of the 2025 cash bonus plan, the Compensation Committee selected the following as the corporate performance measures, all of which are measured over the 2025 fiscal year performance period:

•Revenue Growth, weighted 40%;

•Adjusted EBITDA, weighted 25%;

•New product milestones ((i) Product 1 510(k) submission (weighted 10%), (ii) Product 2 510(k) submission or First in Patient use (“FIP”) (weighted 10%), and (iii) Product 3 FIP (weighted 5%)); and

•People and culture metric weighted 10% based on achievement to a retention rate target.

In addition, the 2025 cash bonus plan provided an upside opportunity of 5% of target bonus if the Company’s employee engagement score, based on the average results of two surveys administered through the Energage platform during 2025, increases by at least two percentage points year-over-year. Engagement performance is measured in percentage points, not percentage change. This engagement component operates solely as a positive modifier and does not reduce payouts if the target is not achieved.


SI-BONE, Inc.			37			2026 Proxy Statement

The Compensation Committee believed these performance measures were appropriate for our business because they provide a balance between generating revenue, managing our expenses, and growing our business, which it believes most directly influence long-term stockholder value. At the same time, the Compensation Committee established target performance levels for each of these measures at levels that it believed to be challenging, but attainable, through the successful execution of our annual operating plan.

Potential payouts under the 2025 cash bonus plan range from 0% if the threshold performance level is not met, 80% of target at threshold performance, 125% of target for upper performance, and, for revenue growth, 150% of target for maximum performance. The actual bonus payouts under the 2025 cash bonus plan with respect to each corporate performance measure are determined independently. For 2025, the threshold, target, upper and maximum levels of achievement for each corporate performance measure, were as follows.

2025 Performance Results and Bonus Decisions

In January 2026, the Compensation Committee approved (recommended to our Board of Directors in the case of our CEO) our actual achievement with respect to the corporate performance objectives under the 2025 cash bonus plan as follows:


Corporate Performance Measure	Weight (%)	Actual Achievement	Achievement Payout Level (%)	Bonus Contribution (%)

Revenue Growth	40	20.2%	110	44.0
Adjusted EBITDA	25	$8.9M	125	31.2

SI-BONE, Inc.			38			2026 Proxy Statement

The Compensation Committee determined that, (i) based on our actual performance with respect to each corporate performance measure, the corporate performance objectives had been achieved, in the aggregate, at a level resulting in payout of 106.5% of target and (ii) based on our actual performance with respect to the employee engagement score component, the target engagement performance had not been achieved. Accordingly, the Compensation Committee (our Board of Directors in the case of our CEO) approved bonus payments as follows for our Named Executive Officers:


Named Executive Officer	Target Annual Cash Bonus Opportunity ($)	Bonus Achievement Percentage (%)	Actual Annual Cash Bonus Payment ($)

Laura A. Francis	685,000	106.5	729,525
Anshul Maheshwari	298,001	106.5	317,371
Anthony J. Recupero	375,435	106.5	399,838
Michael A. Pisetsky	246,704	106.5	262,739

The actual annual cash bonuses paid to our Named Executive Officers for 2025 are also set forth in the “2025 Summary Compensation Table” below.

Long-Term Incentive Compensation

We use long-term incentive compensation in the form of equity awards to motivate our executive officers, including our Named Executive Officers, by providing them with the opportunity to build an equity interest in the company and to share in the potential appreciation of the value of our common stock. The Compensation Committee views equity awards, whether the awards are subject to time-based vesting requirements or are to be earned based on the attainment of specific performance objectives, as inherently variable since the grant date fair value of these awards may not necessarily be indicative of their value when, and if, the shares of our common stock underlying these awards are ever earned or vested. The Compensation Committee further believes these awards enable us to attract and retain key talent in our industry and align our executive officers’ interests with the long-term interests of our stockholders.

Generally, in determining the size of the equity awards granted to our executive officers, the Compensation Committee takes into consideration the recommendations of our CEO (except with respect to her own equity awards), and other factors, including the comparative awards granted to similar positions at our peer companies, the performance and expected performance of the executive officer, the existing equity holdings of each executive officer, including the current economic value of their unvested equity awards and the ability of these unvested holdings to satisfy our retention objectives, overall market data, and information provided by our compensation consultant. The Compensation Committee also considers the dilutive effect of our long-term incentive compensation practices, and the overall impact that these equity awards, as well as awards to other employees, will have on stockholder value.

In February 2025, the Compensation Committee (our Board of Directors in the case of our CEO) granted PSU awards and RSU awards to our Named Executive Officers. The PSUs granted to Ms. Francis are weighted 75% based on relative total shareholder return (“TSR”) and 25% based on financial performance metrics, while the PSUs granted to Messrs. Maheshwari, Recupero, and Pisetsky are 100% based on relative TSR. The Compensation Committee determined Ms. Francis’ 2025 long-term incentive mix would be 50% PSUs and 50% RSUs, and Messrs. Maheshwari, Recupero, and Pisetsky’s mix would be 25% PSUs and 75% RSUs. The Compensation Committee determined the mix of RSUs and PSUs for each of our Named Executive Officers with reference to market norms and predominant practices among our peer companies. The equity awards granted to our Named Executive Officers in 2025 were as follows:


Named Executive Officer	Number of RSUs (#)	Target Number of Financial-based PSUs (#)	Target Number of Relative TSR PSUs (#)	Total Target Value(1) ($)

Laura A. Francis	122,315	30,579	91,736	4,099,999
Anshul Maheshwari	71,599	—	23,866	1,599,993
Anthony J. Recupero	55,937	—	18,646	1,250,011
Michael A. Pisetsky	58,174	—	19,391	1,299,989

1.The amounts reported in this column represent the target value of equity awards made in 2025. The target value assumes the payout of the PSU component at Target or 100%. This differs from the aggregate grant date fair value of awards as computed in accordance with FASB ASC 718 and reported in the “2025 Summary Compensation Table” below. Target values were converted to shares using our stock price of $16.76 as of January 31, 2025.


SI-BONE, Inc.			39			2026 Proxy Statement

Relative TSR PSUs

The relative TSR PSU awards are designed to be earned based on our TSR as compared to a group of industry peers in equal tranches over one-, two-, and three-year performance periods. In each period, the target performance is the median of the industry peer group. A maximum payout of 200% of target is earned if the company’s performance exceeds the industry group median by 50 percentage points or more; no payout is earned if the company’s performance trails the industry group median by 50 percentage points or more.

The PSUs granted to our Named Executive Officers in February 2025 include interim payout opportunities after the end of the first and second years of the three-year performance period. The first interim payout opportunity is capped at one-third of the target level payout for the PSUs, while up to 200% of the target shares associated with the second-year performance period may be earned following that performance period, based on relative TSR performance and continued service through the end of the relevant year. Up to 200% of the total target shares under the whole award may be earned after the conclusion of the three-year performance period based on relative TSR performance through the end of the three-year performance period, less any shares previously earned and paid out for the first and second interim periods.

The group of relative TSR industry peers was selected using objective criteria determined in advance of the start of the performance period. For 2025, the Compensation Committee determined to include constituents of the S&P Healthcare Equipment Select Index and other executive compensation peers with market cap between ~0.25x and ~4.0x SI-BONE.

The RSU awards granted to our Named Executive Officers in February 2025 are subject to a time-based vesting requirement providing that these awards are to vest quarterly over four years, subject to the continued service of the applicable Named Executive Officers on each such vesting date.
