Forward-looking statements are based upon various estimates and assumptions, as well as information known to us as of the date hereof and are subject to risks and uncertainties. Accordingly, actual results could differ materially from those expressed or implied due to a variety of factors.

1535 Steele Avenue SW, Suite B

Grand Rapids, Michigan 49507

**PROXY STATEMENT FOR THE 2026 ANNUAL MEETING OF STOCKHOLDERS JUNE 26, 2026**

We have sent you this Proxy Statement and the enclosed proxy card because the Board of Directors (the "Board") of Shoulder Innovations, Inc., a Delaware corporation (referred to herein as the "Company," "Shoulder Innovations," "we," "us," or "our") is soliciting your proxy to vote at our 2026 Annual Meeting of Stockholders (the "Annual Meeting"), which will be held on Friday, June 26, 2026, at 3:00 p.m. Eastern Time. The Annual Meeting will be held online at www.virtualshareholdermeeting.com/SI2026.

• This Proxy Statement summarizes information about the proposals to be considered at the Annual Meeting and other information you may find useful in determining how to vote.

• The proxy card is the means by which you authorize another person to vote your shares in accordance with your instructions.

Pursuant to the "Notice and Access" rules adopted by the SEC, we have elected to provide access to our proxy materials, which include the Notice of the 2026 Annual Meeting of Stockholders, this Proxy Statement and the accompanying proxy card and our Annual Report, over the internet in lieu of mailing printed copies. We will begin mailing the Notice of Internet Availability to our stockholders of record as of April 27, 2026 (the "Record Date") for the first time on or about April 29, 2026. The Notice of Internet Availability will contain instructions on how to access and review the proxy materials and will also contain instructions on how to request a printed copy of the proxy materials. In addition, we have provided brokers, dealers, banks, voting trustees, and their nominees, at our expense, with additional copies of our proxy materials so that our stockholders of record can supply these materials to the beneficial owners of shares of our common stock as of the Record Date. The Annual Report is also available in the "*Investors—Financial Information—SEC Filings*" section of our website at www.shoulderinnovations.com.

The only outstanding voting securities of Shoulder Innovations are shares of common stock, $0.001 par value per share (the "common stock"), of which there were 20,727,949 shares outstanding as of the Record Date. The holders of a majority in voting power of the shares of common stock issued and outstanding and entitled to vote, present by remote communication or represented by proxy, are required to constitute a quorum for the transaction of business at the Annual Meeting.

&nbsp;&nbsp;&nbsp;&nbsp;2026 Proxy Statement 1

------

**INFORMATION ABOUT THE PROXY PROCESS AND VOTING**

**Why am I receiving these materials?**

We have made the Notice of the Annual Meeting, the Proxy Statement and accompanying proxy card and the Annual Report available to you on the internet or, upon your request, have delivered printed proxy materials to you, because the Board is soliciting your proxy to vote at the Annual Meeting, including at any adjournments or postponements of the Annual Meeting. You are invited to attend the Annual Meeting online to vote on the proposals described in this Proxy Statement. However, you do not need to attend the Annual Meeting to vote your shares. Instead, you may complete, sign, and return the proxy card, or follow the instructions below to submit your proxy over the telephone or on the internet.

The Notice of Internet Availability, the Notice of the Annual Meeting, the Proxy Statement and accompanying proxy card and the Annual Report will be first made available for access on or about April 29, 2026, to all stockholders of record entitled to vote at the Annual Meeting.

**Who can vote at the Annual Meeting?**

Only stockholders of record at the close of business on the Record Date will be entitled to vote at the Annual Meeting. At the close of business on the Record Date, there were 20,727,949 shares of common stock issued and outstanding and entitled to vote.

*Stockholder of Record*

If, on the Record Date, your shares were registered directly in your name with the transfer agent for our common stock, Broadridge Corporate Issuer Solutions, LLC, then you are a stockholder of record. As a stockholder of record, you may vote at the Annual Meeting by attending the Annual Meeting online or you may vote by proxy. Whether or not you plan to attend the Annual Meeting online, we encourage you to fill out and return the proxy card or vote by proxy over the telephone or on the internet as instructed below to ensure your vote is counted.

*Beneficial Owner*

If, on the Record Date, your shares were held in an account at a brokerage firm, bank, dealer, custodian, or other similar organization acting as nominee (each, a "broker"), then you are the beneficial owner of shares held in "street name" and these proxy materials are being forwarded to you by your broker. The broker holding your account is considered the stockholder of record for purposes of voting at the Annual Meeting. As a beneficial owner, you have the right to direct your broker or other agent on how to vote the shares in your account.

**What am I being asked to vote on?**

You are being asked to vote on two proposals:

• Proposal No. 1—the election of two Class I directors, each to serve a three-year term until the 2029 annual meeting of stockholders and until the election and qualification of such director's successor, or such director's earlier death, resignation, or removal; and

• Proposal No. 2—the ratification of the appointment of Deloitte & Touche LLP as our independent registered public accounting firm for the year ending December 31, 2026.

In addition, you are entitled to vote on any other matters that are properly brought before the Annual Meeting.

&nbsp;&nbsp;&nbsp;&nbsp;2026 Proxy Statement 2

------

**How do I vote?**

• For Proposal No. 1, you may either vote "For" the nominees to the Board or you may "Withhold" your vote for the nominees.

• For Proposal No. 2, you may either vote "For" or "Against" or abstain from voting.

Please note that by casting your vote by proxy, you are authorizing the individuals listed on the proxy card to vote your shares in accordance with your instructions and in their discretion with respect to any other matter that properly comes before the Annual Meeting or any adjournments or postponements thereof.

The procedures for voting are as follows:

*Stockholder of Record*

If you are a stockholder of record, you may vote at the Annual Meeting online by logging in at www.virtualshareholdermeeting.com/SI2026 and entering the 16-digit control number listed on your proxy card. Alternatively, you may vote by proxy before the Annual Meeting in the following ways:

• via the internet at www.ProxyVote.com;

• by telephone by calling 1-800-690-6903; or

• by signing and returning the proxy card in the supplied prepaid business reply envelope included in your proxy materials to Vote Processing, c/o Broadridge, 51 Mercedes Way, Edgewood, NY 11717.

Whether or not you plan to attend the Annual Meeting online, we encourage you to vote by proxy to ensure your vote is counted. Even if you have submitted a proxy before the Annual Meeting, you may still attend the Annual Meeting online and vote online. In such case, your previously submitted proxy will be disregarded.

*Beneficial Owner*

If you are a beneficial owner, you should have received a voting instruction card and voting instructions with these proxy materials from your broker. To ensure your vote is counted, you must complete and mail the voting instruction card. To vote at the Annual Meeting online, you must obtain a valid proxy from your broker. Follow the instructions from your broker included with these proxy materials or contact your broker to request a proxy form.

**Who counts the votes?**

A delegate of Broadridge Financial Services, Inc. will serve as the inspector of election (the "Inspector of Election").

**How are votes counted?**

Votes will be counted by the Inspector of Election, who will separately count "For" votes for all proposals, and, with respect to Proposal No. 2, "Against" votes, abstentions, and broker non-votes (if any). In addition, with respect to Proposal No. 1, the Inspector of Election will count the number of "Withheld" votes and broker non-votes received.

**What are "abstentions"?**

Abstentions occur when shares of our common stock present at the Annual Meeting are marked "Abstain." Under Delaware law, abstentions are counted as present and entitled to vote for purposes of determining whether a quorum is present. At the Annual Meeting, pursuant to Delaware law and the terms of our Amended and Restated Certificate of Incorporation (the "Certificate of Incorporation") and our Amended and Restated Bylaws (the "Bylaws"), abstentions and, with respect to Proposal No. 1, proxies marked "Withhold" for either one of the nominees to the Board will have no effect on Proposal No. 1 for the election of such nominee to the Board. Abstentions will have no effect on Proposal No. 2.

&nbsp;&nbsp;&nbsp;&nbsp;2026 Proxy Statement 3

------

**What are "broker non-votes"?**

Broker non-votes occur when a beneficial owner of shares held in "street name" does not give instructions to the broker of the shares as to how to vote on matters deemed "non-routine." Generally, if shares are held in "street name," the beneficial owner of the shares is entitled to give voting instructions to the broker holding the shares. If the beneficial owner does not provide voting instructions, the broker can still vote the shares with respect to matters that are considered to be "routine," but not with respect to "non-routine" matters. In the event that a broker or other stockholder of record indicates on a proxy that it does not have discretionary authority to vote certain shares on a particular proposal, then those shares will be treated as broker non-votes with respect to that proposal. Accordingly, if you own shares in "street name," please be sure to instruct your broker how to vote to ensure that your vote is counted on each of the proposals.

**Which proposals are considered "routine" or "non-routine"?**

Proposal No. 2, or the ratification of the appointment of Deloitte & Touche LLP as our independent registered public accounting firm for the year ending December 31, 2026, is considered routine under applicable rules. A broker may generally vote on routine matters, and therefore no broker non-votes are expected to exist in connection with Proposal No. 2.

Proposal No. 1, or the election of two Class I directors, each to serve a three-year term until the 2029 annual meeting of stockholders and until the election and qualification of such director's successor, or such director's earlier death, resignation, or removal, is considered non-routine under applicable rules. A broker cannot vote without instructions on non-routine matters, and therefore there may be broker non-votes on Proposal No. 1.

**How many votes are needed to approve the proposal?**

• With respect to Proposal No. 1, a plurality of the votes cast shall be sufficient to elect a director.

• With respect to Proposal No. 2, the affirmative vote of the holders of a majority in voting power of the votes cast (excluding abstentions and broker non-votes) is required for approval.

**How many votes do I have?**

On each proposal, you have one vote for each share of common stock you own as of the Record Date.

**What if I return a proxy card but do not make specific choices?**

If we receive a signed and dated proxy card that does not specify how your shares are to be voted, your shares will be voted as follows:

• "For" the election of the two nominees for director; and

• "For" the ratification of the appointment of Deloitte & Touche LLP as our independent registered public accounting firm for the year ending December 31, 2026.

If any other matter is properly presented at the Annual Meeting, your proxy (one of the individuals named on your proxy card) will vote your shares in his or her discretion.

**Who is paying for this proxy solicitation?**

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

&nbsp;&nbsp;&nbsp;&nbsp;2026 Proxy Statement 4

------

**What does it mean if I receive more than one set of materials?**

If you receive more than one set of materials, your shares are registered in more than one name or are registered in different accounts. In order to vote all the shares you own, you must either sign and return all of the proxy cards or follow the instructions for any alternative voting procedure on each of the proxy cards.

**Can I change my vote after submitting my proxy?**

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

• submitting another properly completed proxy with a later date;

• sending a written notice that you are revoking your proxy to Shoulder Innovations, Inc., Attn: Corporate Secretary, 1535 Steele Avenue SW, Suite B, Grand Rapids, Michigan 49507; or

• attending the Annual Meeting online and voting during the Annual Meeting. Simply attending the Annual Meeting online will not, by itself, revoke your proxy.

If your shares are held by your broker, you should follow the instructions provided by them.

**How do I attend the virtual Annual Meeting?**

The live audio webcast of the Annual Meeting will begin promptly at 3:00 p.m. Eastern Time on Friday, June 26, 2026. Online access to the audio webcast will open approximately 15 minutes prior to the start of the Annual Meeting to allow time for our stockholders to log in and test their devices' audio system. We encourage you to access the meeting in advance of the designated start time.

To attend the Annual Meeting, you will need to log in at www.virtualshareholdermeeting.com/SI2026 by using the 16-digit control number listed on your proxy card.

**Is technical assistance provided before and during the virtual Annual Meeting?**

Beginning 15 minutes prior to the start of and during the virtual Annual Meeting, we will have a support team ready to assist stockholders with any technical difficulties they may have accessing or hearing the virtual meeting.

If you encounter any difficulties accessing the virtual meeting during the check-in or meeting time, please call the technical support number that will be posted on the virtual stockholder meeting log in page.

**When are stockholder proposals due for the 2027 annual meeting of stockholders?**

Our stockholders are entitled to present proposals for action at a forthcoming meeting if they comply with the requirements of our Certificate of Incorporation, our Bylaws, and the rules established by the SEC.

To be considered for inclusion in next year's proxy materials for the 2027 annual meeting of stockholders under Rule 14a-8 under the Securities Exchange Act of 1934, as amended (the "Exchange Act"), your proposal must be submitted in writing by December 30, 2026, to Shoulder Innovations, Inc., Attn: Corporate Secretary, 1535 Steele Avenue SW, Suite B, Grand Rapids, Michigan 49507.

Pursuant to our Bylaws, in order for a stockholder to present a proposal for the 2027 annual meeting of stockholders, other than proposals to be included in the proxy statement as described above, or to nominate a director, you must do so between February 26, 2027 and March 28, 2027; provided, however, that if the date of the 2027 annual meeting of stockholders is more than 30 days before or more than 60 days after June 26, 2027, you must give notice not earlier than the 120th day prior to such annual meeting date and not later than the 90<sup>th</sup> day prior to such annual meeting date or, if later, the 10<sup>th</sup> day following the day on which disclosure of such annual meeting date is first made public. You are also advised to review our Bylaws, which contain additional requirements about advance notice of stockholder proposals and director nominations. In addition to satisfying the foregoing requirements under our Bylaws, to comply with the universal proxy rules,

&nbsp;&nbsp;&nbsp;&nbsp;2026 Proxy Statement 5

------

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, to the extent applicable.

**What is the quorum requirement?**

A quorum of stockholders is necessary to hold a valid meeting. A quorum will be present if the holders of a majority in voting power of the shares of common stock issued and outstanding and entitled to vote are present by remote communication or represented by proxy at the Annual Meeting. On the Record Date, there were 20,727,949 shares outstanding and entitled to vote.

Your shares will be counted toward the quorum only if you submit a valid proxy or vote at the Annual Meeting online. Abstentions and broker non-votes will be counted toward the quorum requirement. If there is no quorum, either the chair of the Annual Meeting or a majority in voting power of the stockholders entitled to vote at the Annual Meeting present by remote communication or represented by proxy, may adjourn the Annual Meeting to another time or place.

**How can I find out the results of the voting at the Annual Meeting?**

Voting results will be announced by the filing of a Current Report on Form 8-K within four business days after the Annual Meeting. If final voting results are unavailable at that time, we will file an amended Current Report on Form 8-K within four business days of the day the final results are available.

**Implications of being an "emerging growth company."**

We are an "emerging growth company" as that term is used in the Jumpstart Our Business Startups Act of 2012 and, as such, have elected to comply with certain reduced public company reporting requirements. These reduced reporting requirements include reduced disclosure about our executive compensation arrangements and no non-binding advisory votes on executive compensation. We will remain an emerging growth company until the earlier of: (a) the last day of the fiscal year following the fifth anniversary of the consummation of our initial public offering, (b) the last day of the fiscal year in which we have total annual gross revenue of at least $1.235 billion, (c) the last day of the fiscal year in which we are deemed to be a large accelerated filer, which means the market value of our common stock that is held by non-affiliates exceeds $700.0 million as of the last business day of the second fiscal quarter of such year, or (d) the date on which we have issued more than $1.0 billion in non-convertible debt during the prior three-year period.

**PROPOSAL NO. 1 ELECTION OF CLASS I DIRECTORS**

Our Board currently consists of eight members who are divided into three classes, designated as Class I, Class II, and Class III. Each class has a staggered, three-year term. Class I directors' terms expire at the Annual Meeting, Class II directors' terms expire at the 2027 annual meeting of stockholders, and Class III directors' terms expire at the 2028 annual meeting of stockholders. At each annual meeting of stockholders, directors whose terms are expiring will be succeeded by newly-elected directors, who will serve from the time of their election and qualification until the third subsequent annual meeting of stockholders. Vacancies on the Board may be filled by persons elected by a majority of the directors then in office, although less than a quorum, or by a sole remaining director, and such persons shall serve for the remainder of the full term of the class of directors in which the vacancy occurred and until their successors are elected and qualified.

The Board has nominated Robert Ball and Andrew Hykes to serve as Class I directors until the 2029 annual meeting of stockholders or until their successors are duly elected and qualified. Each of Messrs. Ball and Hykes has agreed to serve if elected, and there is no reason to believe that any of them will be unable to serve. On March 6, 2026, Michael Carusi, a Class I director, notified the Company of his intention to not stand for re-election as a Class I director at the Annual Meeting upon the conclusion of his current term. Mr. Carusi's term with the Board will conclude effective following the Annual Meeting, and the Board has resolved to decrease the size of the Board to seven directors effective upon the election of the Company's directors at the Annual Meeting.

Shares represented by executed proxies will be voted, if authority to do so is not withheld, for the election of Messrs. Ball and Hykes. In the event that a nominee should be unavailable for election as a result of an unexpected occurrence, such shares will be voted for the election of such substitute nominee as the Board may propose. Alternatively, the Board may leave the position vacant and/or reduce the size of the Board.

Each director will be elected by a plurality of the votes cast at the Annual Meeting. This means that the two individuals nominated for election to the Board at the Annual Meeting receiving the highest number of "FOR" votes will be elected. You may vote "FOR" either one of the nominees to the Board, or you may "WITHHOLD" with respect to the nominees to the Board. Shares represented by proxies will be voted "FOR" the election of each of the Class I nominees, unless the proxy is marked to withhold authority to so vote.

The following table sets forth information with respect to our two director nominees and the continuing directors, as of the Record Date.

**PROPOSAL NO. 2 RATIFICATION OF SELECTION OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM**

The Audit Committee has appointed Deloitte & Touche LLP ("Deloitte") as our independent registered public accounting firm for the year ending December 31, 2026, and is seeking ratification of such selection by our stockholders at the Annual Meeting. Deloitte has audited our financial statements for each of our fiscal years since the year ended December 31, 2023.

Although ratification of the Audit Committee's appointment of Deloitte is not required, we value the opinions of our stockholders and believe that stockholder ratification is a good corporate governance practice. If this proposal does not receive the affirmative approval of a majority of the voting power of the votes cast (excluding abstentions and broker non-votes) at the Annual Meeting, the Audit Committee would reconsider the appointment of Deloitte as our independent registered public accounting firm for the year ending December 31, 2026. Notwithstanding its selection, and even if our stockholders ratify the selection, our Audit Committee, in its discretion, may appoint another independent registered public accounting firm at any time during the year ending December 31, 2026 if the Audit Committee believes that such a change would be in our best interests and the interests of our stockholders.

Representatives of Deloitte are expected to be in attendance online at the Annual Meeting, will have an opportunity to make a statement if they so desire, and will be available to respond to appropriate questions.

**Principal Accountant Fees and Services**

The Audit Committee has considered the scope and fee arrangements for all services provided by Deloitte, taking into account whether the provision of non-audit-related services is compatible with maintaining Deloitte's independence. The following table represents aggregate fees billed by Deloitte for the years ended December 31, 2025 and 2024.

(1)"Audit Fees" consist of fees for professional services provided primarily in connection with the annual audit of our financial statements, quarterly reviews and services associated with SEC registration statements and other documents issued in connection with our initial public offering including comfort letters and consents.

**Pre-Approval Policies and Procedures**

The Audit Committee's charter mandates that the Audit Committee or its delegate pre-approve all audit and non-audit services provided by its independent registered public accounting firm, unless the engagement is entered into pursuant to appropriate additional pre-approval policies established by the Audit Committee or if such service falls within available exceptions under SEC rules. In accordance with its charter, the Audit Committee approved all of the audit services provided by Deloitte for the years ended December 31, 2025 and 2024, including the audit services provided by Deloitte following our initial public offering, and in each case, the estimated costs of those services. Actual amounts billed, to the extent in excess of the estimated amounts, are periodically reviewed and approved by the Audit Committee.

**REPORT OF THE AUDIT COMMITTEE OF THE BOARD OF DIRECTORS**

The material in the following Report of the Audit Committee is not considered "soliciting material," is not deemed "filed" with the Securities and Exchange Commission (the "SEC"), and is not to be incorporated by reference into any filing of Shoulder Innovations, Inc. ("Shoulder Innovations" or "our") under the Securities Act of 1933, as amended, or the Securities Exchange Act of 1934, as amended.

The primary purpose of the Audit Committee is to oversee our financial reporting processes on behalf of our Board. The Audit Committee's functions are more fully described in its charter, which is available in the "*Investors—Corporate Governance—Documents & Charters*" section of our website at www.shoulderinnovations.com. Management has the primary responsibility for our financial statements and reporting processes, including our systems of internal controls. In fulfilling its oversight responsibilities, the Audit Committee reviewed and discussed with management Shoulder Innovations' audited financial statements as of and for the year ended December 31, 2025.

The Audit Committee has discussed with Deloitte & Touche LLP ("Deloitte"), Shoulder Innovations' independent registered public accounting firm, the matters required to be discussed by the applicable requirements of the Public Company Accounting Oversight Board (the "PCAOB") and the SEC. In addition, the Audit Committee has received the written disclosures and the letter from Deloitte required by applicable requirements of the PCAOB regarding Deloitte's communications with the Audit Committee concerning independence, and the Audit Committee has discussed with Deloitte their independence from the Company and its management. Finally, the Audit Committee discussed with Deloitte, with and without management present, the scope and results of Deloitte's audit of such financial statements.

Based on these reviews and discussions, the Audit Committee has recommended to our Board of Directors that such audited financial statements be included in Shoulder Innovations' Annual Report on Form 10-K for the year ended December 31, 2025, for filing with the SEC.

**CORPORATE GOVERNANCE**

**Code of Ethics and Conduct**

We have adopted a written Code of Ethics and Conduct that applies to all of our directors, officers, and employees, including our principal executive officer, principal financial officer, and principal accounting officer or controller, or persons performing similar functions, and agents and representatives. The full text of our Code of Ethics and Conduct is available in the "*Investors—Corporate Governance—Documents & Charters*" section of our website at www.shoulderinnovations.com. Reference to our website does not constitute incorporation by reference of the information contained at or available through our website into this Proxy Statement.

The Audit Committee of our Board is responsible for overseeing our Code of Ethics and Conduct and any waivers applicable to any director, executive officer, or employee. We intend to disclose any future amendments to certain provisions of our Code of Ethics and Conduct, or waivers of such provisions applicable to our directors, officers, and employees, including our principal executive officer, principal financial officer, principal accounting officer or controller, or persons performing similar functions, and agents and representatives, on our website identified above or in public filings.

**Corporate Governance Guidelines**

We endeavor to maintain sound corporate governance policies and practices and have adopted formal Corporate Governance Guidelines to enhance our effectiveness. Our Board adopted the Corporate Governance Guidelines in order to ensure that it has the necessary practices in place to review and evaluate our business operations as needed and to make decisions that are independent of our management. The Corporate Governance Guidelines are also intended to align the interests of directors with those of our stockholders. The Corporate Governance Guidelines set forth the practices our Board follows with respect to, among other things, Board and committee composition and selection, Board meetings, and succession planning. A copy of our Corporate Governance Guidelines is available in the "*Investors—Corporate Governance—Documents & Charters*" section of our website at www.shoulderinnovations.com.

**Independence of the Board**

As required under the New York Stock Exchange ("NYSE") rules and regulations, a majority of the members of a listed company's board of directors must qualify as "independent," as affirmatively determined by such board. The Board consults with the Company's counsel to ensure that the Board's determinations are consistent with all relevant securities and other laws and regulations regarding the definition of "independent," including those set forth in pertinent NYSE rules, as in effect from time to time.

Our Board has determined that each of the following continuing directors and director nominees qualify as "independent" directors in accordance with the rules of the NYSE: Paul Buckman, Michael Carusi, Casey Tansey, Kevin Sidow, Andrew Hykes and Richard J. Buchholz. Additionally, the Board has determined that Geoff Pardo, who served as a director from February 2023 to February 2026, was independent during his period of service as a director. Messrs. Ball and Ahearn are not considered independent by virtue of their position as our Chief Executive Officer and Chief Operating Officer, respectively. Under the NYSE rules, the definition of independence includes a series of objective tests, such as that the director is not, and has not been for at least three years, one of our employees and that neither the director nor any of his or her family members has engaged in various types of business dealings with us. In addition, as required by the NYSE rules, our Board has made a subjective determination as to each independent director that no relationship exists that, in the opinion of our Board, would interfere with the exercise of independent judgment in carrying out the responsibilities of a director. In making these determinations, our Board reviewed and discussed information provided by the directors and us with regard to each director's business and personal activities and relationships as they may relate to us and our management. There are no current family relationships among any of our directors or executive officers.

&nbsp;&nbsp;&nbsp;&nbsp;2026 Proxy Statement 12

------

As required under NYSE rules and regulations, our independent directors meet in regularly scheduled executive sessions at which only independent directors are present. Each of the Audit Committee, Compensation Committee, and Nominating and Corporate Governance Committee of our Board is comprised entirely of directors determined by the Board to be independent within the meaning of the NYSE and SEC rules and regulations applicable to the members of such committees.

**Leadership Structure of the Board**

Our Corporate Governance Guidelines provide our Board with flexibility to combine or separate the positions of Chair of the Board and Chief Executive Officer and to implement a lead independent director in accordance with its determination regarding which structure would be in the best interests of the Company. Mr. Ball currently serves as the Chief Executive Officer and Executive Chairman of the Board, and Mr. Buckman has served as our Lead Independent Director since April 2026. The Board believes that its current leadership structure is appropriate, as it allows the Chief Executive Officer to focus on managing the Company, while leveraging our Lead Independent Director's experience to drive accountability at the Board level and carry out its roles and responsibilities on behalf of the Company's stockholders, including its oversight of management and corporate governance matters. Our Lead Independent Director is responsible for coordinating the activities of the independent directors, including:

• presiding over all meetings of the Board at which the Chairman of the Board is not present, including any executive sessions;

• approving Board meeting schedules and agendas;

• acting as a liaison between the independent directors and the Chief Executive Officer and the Chairman of the Board;

• convening meetings of the independent directors as appropriate;

• being available for consultation and direct communication with stockholders as appropriate; and

• performing such other functions as the Board may delegate.

Our Board is committed to continuously reviewing its leadership structure and composition, along with its policies and practices, as our Company grows and evolves.

**Role of Board in Risk Oversight Process**

Risk assessment and oversight are an integral part of our governance and management processes. Our Board encourages management to promote a culture that incorporates risk management into our corporate strategy and day-to-day business operations. Management discusses strategic and operational risks regularly at management meetings, and conducts specific strategic planning and review sessions during the year that include a focused discussion and analysis of the strategic risks facing the Company. Throughout the year, our management team reviews these strategic risks with the Board regularly at Board meetings as part of management presentations that focus on particular business functions, operations, or strategies, and presents the steps taken by management to mitigate or eliminate such risks.

Our Board does not have a standing risk management committee, but rather administers this oversight function directly through our Board as a whole, as well as through various standing committees of our Board that address risks inherent in their respective areas of oversight. While our Board is responsible for monitoring and assessing strategic risk exposure, our Audit Committee is responsible for overseeing company-wide and information security risk assessment processes, our major financial risk exposures, regulatory compliance, and the steps our management has taken to monitor and control these risks and exposures. The Audit Committee then reviews these matters with the full Board as part of the Audit Committee's regular reports to the Board. The Audit Committee also approves or disapproves any related person transactions. Our Nominating and Corporate Governance Committee monitors the effectiveness of

&nbsp;&nbsp;&nbsp;&nbsp;2026 Proxy Statement 13

------

our Corporate Governance Guidelines and risks related to environmental, social, and governance issues. Our Compensation Committee assesses and monitors whether any of our compensation policies and programs has the potential to encourage excessive risk-taking.

**Cybersecurity Risk Oversight** 

The Company has invested resources in and is committed to maintaining a robust cybersecurity risk management program designed to identify, assess, and mitigate cybersecurity risks, including those related to data breaches, phishing, ransomware, insider threats, third-party relationships, software vulnerabilities, regulatory compliance, cloud security, artificial intelligence, and end-user computing. While everyone at the Company plays a part in managing these risks, our Board as a whole and our Audit Committee oversee and monitor our cybersecurity risks. Information relating to cybersecurity and information security is contained in the section entitled "Cybersecurity" in our Annual Report.

**Board Committees**

Our Board has established an Audit Committee, a Compensation Committee, and a Nominating and Corporate Governance Committee. Our Board may establish other committees to facilitate the management of our business. The composition and functions of each committee are described below. Members serve on these committees until their resignation or until otherwise determined by our Board. Each committee has a written charter that satisfies the applicable rules and regulations of the SEC and NYSE rules, which are available in the "*Investors—Corporate Governance—Documents & Charters*" section of our website at www.shoulderinnovations.com.

*Audit Committee*

Our Audit Committee oversees the integrity of the Company's financial statements, the Company's compliance with legal and regulatory requirements, the qualification and independence of the Company's independent registered public accounting firm, and the performance of the Company's internal audit function and independent registered public accounting firm. Among other matters, the Audit Committee's responsibilities include:

• appointing, engaging, compensating, evaluating, terminating, retaining and overseeing the Company's independent registered public accounting firm;

• approving all audit and permissible non-audit services to be performed by our independent registered public accounting firm;

• reviewing and monitoring our accounting principles, accounting policies, financial and accounting controls, and compliance with legal and regulatory requirements;

• reviewing our policies on risk assessment and risk management, including overseeing financial risks and information technology risks, including cybersecurity and data privacy risks;

• establishing procedures for the receipt, retention and treatment of complaints regarding accounting, internal accounting controls or auditing matters, and confidential and anonymous submissions by employees of concerns regarding questionable accounting, internal accounting controls, fraud or auditing matters;

• providing a report of the Audit Committee for inclusion in the Company's annual proxy statements;

• reviewing and approving related person transactions; and

• reviewing and granting, if appropriate, waivers from the Code of Ethics and Conduct.

Our Audit Committee is composed of Messrs. Buchholz, Buckman and Sidow, with Mr. Buchholz serving as the Chairman of the Audit Committee. Our Board has determined that Messrs. Buchholz, Buckman and Sidow are independent under the NYSE rules and Rule 10A-3(b)(1) of the Exchange Act, and that each of Messrs. Buchholz, Buckman and Sidow are financially literate and an "audit committee financial expert."

&nbsp;&nbsp;&nbsp;&nbsp;2026 Proxy Statement 14

------

*Compensation Committee*

Our Compensation Committee oversees policies relating to the compensation and benefits of our executive officers and directors. Among other matters, the Compensation Committee's responsibilities include:

• reviewing and approving the corporate goals and objectives for the compensation of our Chief Executive Officer, evaluating the performance of the Chief Executive Officer in light of such goals and objectives, and setting the Chief Executive Officer's compensation;

• overseeing the evaluation of the Company's executive officers (other than the Chief Executive Officer) and reviewing and setting, or making recommendations to the Board to set, the compensation of such executive officers;

• reviewing and approving any employment and severance agreements or arrangements for the Company's executive officers;

• reviewing and making recommendations to the Board regarding director compensation;

• administering, reviewing, approving or making recommendations to the Board regarding the Company's incentive compensation and equity-based plans and arrangements;

• reviewing and discussing annually with management our "Compensation Discussion and Analysis" disclosure and a report of the Compensation Committee for inclusion in the Company's annual proxy statements, if and to the extent then required by SEC rules;

• appointing and overseeing any compensation consultants; and

• administering and overseeing the Company's Policy for Recovery of Erroneously Awarded Compensation (the "Clawback Policy").

Our Compensation Committee is composed of Messrs. Hykes, Sidow, and Tansey, with Mr. Sidow serving as the Chairman of the Compensation Committee. Our Board has determined that all members are non-employee directors, are independent under and meet all requirements imposed under the rules of the NYSE and SEC.

The Compensation Committee has retained FW Cook, an independent executive compensation consulting firm, to advise the committee on executive and non-employee director compensation levels and design, including our peer group, our incentive compensation plans, our compensation-related disclosures, and other material compensation decisions. In compliance with the disclosure requirements of the SEC regarding the independence of compensation consultants, FW Cook addressed each of the six independence factors established by the SEC with the Compensation Committee. Each of the responses affirmed the independence of FW Cook on executive compensation matters. Based on this assessment, the Compensation Committee determined that the engagement of FW Cook does not raise any conflicts of interest or similar concerns. In addition, the Compensation Committee evaluated the independence of its other outside advisors to the Compensation Committee, including outside legal counsel, based on the same independence factors and concluded their service does not raise any conflicts of interest.

*Nominating and Corporate Governance Committee*

Our Nominating and Corporate Governance Committee oversees the identification of individuals qualified to serve on the Board and the development and recommendation to the Board of corporate governance policies and practices. Among other matters, the Nominating and Corporate Governance Committee's responsibilities include:

• identifying individuals qualified to become members of our Board, consistent with criteria approved by our Board, and ensuring that the Board has the requisite expertise;

• reviewing and recommending to the Board changes to the Board's committee structure and individuals qualified to serve on each of the Board's committees;

• reviewing and assessing the appropriateness of the Company's Board leadership structure;

&nbsp;&nbsp;&nbsp;&nbsp;2026 Proxy Statement 15

------

• reviewing and assessing the adequacy of the Company's Corporate Governance Guidelines and recommending any changes to the Board;

• overseeing the annual self-assessments of the Board and its committees;

• making recommendations to the Board regarding governance matters; and

• reviewing and overseeing the Company's strategy, initiatives, policies and risks concerning environmental and social matters.

Our Nominating and Corporate Governance Committee is composed of Messrs. Buckman, Buchholz and Tansey, with Mr. Buckman serving as Chairman of the Nominating and Corporate Governance Committee. Our Board has determined that all members are independent under the rules of the NYSE.

Our Nominating and Corporate Governance Committee, in recommending director candidates for election to the Board, and the Board, in nominating director candidates, will consider candidates who have a high level of personal and professional integrity, strong ethics and values and the ability to make mature business judgments as set out in our Corporate Governance Guidelines. In evaluating director candidates, the Nominating and Corporate Governance Committee may consider, among other things, a candidate's: (i) experience in corporate management; (ii) experience as a Board member of other companies; (iii) professional and academic experience relevant to the Company's industry; (iv) leadership skills and any potential conflicts of interest; (v) experience in finance and accounting and/or executive compensation practices; (vi) capacity and ability to dedicate the time required for the preparation, participation and attendance at Board meetings and meetings of the Board's committees, if applicable; and (vii) ability to contribute to the mix of experience, backgrounds, qualifications and skills of the Board. Our Nominating and Corporate Governance Committee and the Board may also consider such other factors as it may deem, from time to time, are in the best interests of our Company and our stockholders. Our Board evaluates each individual in the context of the Board as a whole, with the objective of assembling a group that can best maximize the success of the business and represent stockholder interests through the exercise of sound judgment using its diversity of experience in these various areas. Although the Nominating and Corporate Governance Committee may consider whether nominees assist in achieving a mix of Board members that represents a diversity of background and experience, we have no formal policy regarding board diversity.

The Nominating and Corporate Governance Committee will consider director candidates recommended by stockholders. For a stockholder to make any nomination for election to the Board at an annual meeting, the stockholder must provide notice to the Company, which notice must be delivered to, or mailed and received at, the Company's principal executive offices, located at 1535 Steele Avenue SW, Suite B, Grand Rapids, Michigan 49507, not less than 90 days and not more than 120 days prior to the one-year anniversary of the preceding year's annual meeting; provided, however, that if the date of the annual meeting is more than 30 days before or more than 60 days after such anniversary date, the stockholder's notice must be delivered, or mailed and received, not more than 120 days prior to such annual meeting and not later than 90 days prior to such annual meeting or, if later, the 10<sup>th</sup> day following the day on which public disclosure of the date of such annual meeting was first made by the Company. The notice must contain the information required by our Bylaws, and any stockholders who intend to solicit proxies in support of director nominees other than the Company's nominees must also comply with the additional requirements of Rule 14a-19(b) of the Exchange Act, to the extent applicable. Any stockholder wishing to make a nomination for director should review a copy of our Bylaws, as amended and restated to-date, which is available, without charge, from our Corporate Secretary at Shoulder Innovations, Inc., 1535 Steele Avenue SW, Suite B, Grand Rapids, Michigan 49507.

**Meetings of the Board, Board and Committee Member Attendance, and Annual Meeting Attendance**

Our Board met eleven times during 2025. The Audit Committee met four times. The Compensation Committee met four times. The Nominating and Corporate Governance Committee met four times. During 2025, each Board member attended at least 75% of the meetings of the Board and of the committees of the Board on which he served, in each case, to the extent appointed as a Board member at the relevant time of each meeting.

This is our first annual meeting of stockholders as a public company. While we encourage all of our directors and nominees for director to attend our annual meeting of stockholders, attendance is not mandatory.

**Stockholder Communications with the Board**

Should stockholders wish to communicate with the Board or any specified individual directors, such correspondence should be sent to the attention of our Corporate Secretary of the Company at Shoulder Innovations, Inc., 1535 Steele Avenue SW, Suite B, Grand Rapids, Michigan 49507, who will forward the communication to our Board.

**Clawback Policy** 

In July 2025, we adopted the Clawback Policy, which applies to our current and former executive officers (as defined in Rule 10D-1(d) of the Exchange Act). Our Clawback Policy provides that if the Company is required to prepare an accounting restatement to correct the Company's material noncompliance with any financial reporting requirement under securities laws, including restatements that correct an error in previously issued financial statements (i) that is material to the previously issued financial statements, or (ii) that would result in a material misstatement if the error were corrected in the current period or left uncorrected in the current period, then the Company shall recover the portion of any incentive-based compensation that was erroneously awarded unless the Compensation Committee has determined that such recovery would be impractical. Under the terms of our Clawback Policy, incentive-based compensation includes any compensation that is granted, earned, or vested based wholly or in part upon the attainment of one or more financial reporting measures and received by a person: (i) after such person beginning service as an executive officer; (ii) who served as an executive officer at any time during the performance period for that compensation; (iii) while the Company has a class of securities listed on a national securities exchange or association; and (iv) during the applicable three-year period. A copy of our Clawback Policy is filed as Exhibit 97.1 to our Annual Report.

**Insider Trading Policy**

We have adopted an Insider Trading Compliance Policy (the "Insider Trading Policy"), which governs the purchase, sale, and/or other dispositions of our securities by directors, officers, and employees of the Company. Our Insider Trading Policy is designed to promote compliance with insider trading laws by informing, educating and creating reasonable processes to prevent the Company and its directors, officers, and employees from insider trading violations and the appearance of any related improper conduct. The Insider Trading Policy also prohibits the trading of the Company's securities on the basis of material nonpublic information, establishes quarterly blackout periods when directors, officers, and employees of the Company are prohibited from trading in our securities, and requires legal compliance for any insider trading plans intended to rely on the affirmative defense against insider trading liability in accordance with Rule 10b5-1 under the Exchange Act. Additionally, the Insider Trading Policy specifically prohibits (i) short sales, (ii) engaging in transactions in puts, calls or other derivative securities involving the Company's equity securities, (iii) hedging transactions, (iv) pledging securities, and (v) purchasing securities on margin or placing Company securities in a margin account. A copy of our Insider Trading Policy is filed as Exhibit 19.1 to our Annual Report.

**Equity Award Timing Policies and Practices**

Our Compensation Committee has not established policies and practices regarding the timing of stock option grants in relation to the release of material nonpublic information and does not take material nonpublic information into account when determining the timing and terms of stock option awards to executive officers. We do not time the disclosure of material nonpublic information for the purpose of affecting the value of executive compensation. The annual grants of stock options are generally based on a predetermined schedule in January of each year as part of the Company's annual compensation process. Grants of stock options may occur at other times during the year due to business needs, such as for newly hired employees or officers or newly appointed directors. The Board and Compensation Committee does not anticipate the

&nbsp;&nbsp;&nbsp;&nbsp;2026 Proxy Statement 17

------

timing of disclosure of material nonpublic information when determining the timing and terms of such awards. The exercise price of stock options are based on the closing price of the underlying common stock on the grant date, subject to the applicable rules for nonqualified stock options and incentive stock options under the 2025 Incentive Award Plan (the "2025 Plan").

There were no grants of stock options to our named executive officers within four business days before or one business day after the release of material nonpublic information on Forms 8-K, 10-Q, or 10-K in the year ended December 31, 2025. As such, no table of such stock option grants is presented under Item 402(x) of Regulation S-K.

**Related Person Transactions Policy** 

Our Board has adopted the Related Person Transaction Policy and Procedures (the "Related Person Transaction Policy") setting forth the policies and procedures for the review and approval or ratification of related person transactions. A "related person transaction" is defined as an existing or proposed transaction, arrangement or relationship (or any series of similar existing or proposed transactions, arrangements or relationships) in which the Company (including any of its subsidiaries) was, is or will be a participant, the amount involved exceeds $120,000, and in which any related person had, has or will have a direct or indirect material interest; *provided that*, if the Company qualifies as a "smaller reporting company" pursuant to the rules of the SEC, a "related person transaction" is a transaction, arrangement or relationship (or any series of similar transactions, arrangements or relationships) in which the Company (including any of its subsidiaries) was, is or will be a participant and the amount involved exceeds the lesser of (i) $120,000 or (ii) one percent of the average of the Company's total assets at fiscal year-end for the last two completed fiscal years, and in which any related person had, has or will have a direct or indirect material interest. A "related person" is defined as (i) any person who is, or at any time since the beginning of the Company's last fiscal year was, a director or executive officer of the Company or a nominee to become a director of the Company; (ii) any person who is known to be the beneficial owner of more than 5% of any class of the Company's voting securities; and (iii) any immediate family member of any of the foregoing persons, which means any child, stepchild, parent, stepparent, spouse, sibling, mother-in-law, father-in-law, son-in-law, daughter-in-law, brother-in-law or sister-in-law of the director, executive officer, nominee or more than 5% beneficial owner, and any person (other than a tenant or employee) sharing the same household of such director, executive officer, nominee or more than 5% beneficial owner.

The Company's finance team is primarily responsible for developing and implementing processes and procedures to obtain information regarding related persons with respect to potential related person transactions and then determining, based on the facts and circumstances, whether such potential related person transactions do, in fact, constitute related person transactions. In addition, any potential related person transaction that is proposed to be entered into by the Company must be reported to the Company's Chief Financial Officer (or his designee) by both the related person and the person at the Company responsible for such potential related person transaction. If the Company's finance team determines that a transaction or relationship is a related person transaction, then the Chief Financial Officer (or his designee) shall present to the Audit Committee each such related person transaction, including all relevant known facts and circumstances relating thereto. The Audit Committee shall review the relevant known facts and circumstances of each related person transaction, including whether the transaction is on terms comparable

&nbsp;&nbsp;&nbsp;&nbsp;2026 Proxy Statement 21

to those that could be obtained in arm's length dealings with an unrelated third party, whether the transaction is inconsistent with the interests of the Company and its stockholders, and the extent of the related person's interest in the transaction, taking into account the conflicts of interest and corporate opportunity provisions of the Company's organizational documents and Code of Ethics and Conduct, and either approve or disapprove the related person transaction.

**DIRECTOR COMPENSATION**

**Non-Employee Director Compensation Program**

Prior to the consummation of our initial public offering, we did not have a formal policy to provide any cash or equity compensation to our non-employee directors for their service on our Board or the committees of the Board. In connection with our initial public offering, we adopted, and our stockholders approved, a Non-Employee Director Compensation Program (the "Director Compensation Program"), which became effective upon the closing of our initial public offering. The Director Compensation Program is intended to attract and retain non-employee directors and align the interests of our Board and stockholders. The Director Compensation Program consists of cash and equity compensation payable to directors who are not an employee of the Company or any of its parents or subsidiaries (each, an "Eligible Director"). The material terms of the Director Compensation Program are described below.

The Director Compensation Program consists of the following components:

*Cash Compensation*

*Equity Compensation*

• *Initial Awards:* An Eligible Director who was serving on the Board as of the effective date of the Director Compensation Program was granted a RSU award with a value of $115,000, with the number of RSUs subject to the award determined by dividing $115,000 by the price per share to the public of the Company's common stock as determined on the pricing date of the Company's initial public offering (the "Initial Award"). Each Initial Award shall vest in full on the earlier of (i) the one-year anniversary of the effective date of the Director Compensation Program, and (ii) the date of the Annual Meeting, subject to the Eligible Director's continued service through the applicable vesting date.

In addition, each equity award granted to an Eligible Director under the Director Compensation Program will vest in full immediately prior to the occurrence of a "change in control" (as defined in the 2025 Plan).

**Narrative to Summary Compensation Table**

*2025 Salaries*

The named executive officers each receive a base salary to compensate them for services rendered to our Company. The base salary payable to each named executive officer is intended to provide a fixed component of compensation reflecting the executive's skill set, experience, role and responsibilities.

For the year ended December 31, 2025, Messrs. Ball, Points and Blue had annual salaries of $467,944, $378,144 and $364,455, respectively. Their salaries for the year ending December 31, 2026 are $675,000, $470,000 and $400,000, respectively.

*2025 Option Awards*

We have historically used stock options as the primary incentive for long-term compensation to our employees, including our named executive officers, because our employees are only able to profit such awards if our stock price increases relative to the stock option's exercise price, which generally is set at or above the fair market value of our common stock as of the applicable grant date.

In April 2025, our Board, with participation by every independent member of our Board, granted each of Messrs. Ball, Points and Blue a stock option award to purchase an aggregate of 172,650, 34,530 and 51,795 shares of our common stock, respectively (the "2025 Option Awards"). The 2025 Option Awards vest at a rate of 1/4<sup>th</sup> of the total number of shares underlying each stock option on April 1, 2026, and thereafter in 12 equal increments on the last date of each fiscal quarter beginning on June 30, 2026, subject to the named executive officer's continued employment through the applicable vesting date.

*2025 Non-Equity Incentive Plan Compensation*

For the year ended December 31, 2025, our named executive officers were eligible to earn a cash incentive bonus based on our achievement of pre-determined revenue, Adjusted EBITDA and personal goals (the "2025 Bonus Plan"). Pursuant to the 2025 Bonus Plan, the revenue and Adjusted EBITDA performance goals and personal goals were weighted as 60%, 20% and 20% of each named executive officer's quarterly bonus opportunity, respectively. For the year ended December 31, 2025, the target bonuses for Messrs. Ball, Points and Blue were 50% of each named executive officer's respective base salary, and the named executive officers were eligible to receive up to 200% of the executive's target bonus opportunity upon achievement of maximum financial goals.

**2025 Outstanding Equity Awards at Fiscal Year-End** 

The following table summarizes the number of shares of common stock underlying outstanding stock option awards for each named executive officer as of December 31, 2025.

**Executive Compensation Arrangements**

*Employment Arrangements*

The following is a description of the employment agreements that were in effect in 2025 with each of our named executive officers.

Each of the agreements is an "at will" employment agreement, pursuant to which Messrs. Ball, Points and Blue are entitled to receive a base salary, which was originally $400,000, $360,000 and $300,000, respectively, at the time such agreements were entered into. Each of the employment agreements also provided for an annual performance bonus of up to 50% of base salary at the time such agreements were entered into. This annual performance bonus was payable on a quarterly basis and was based on both individual and Company performance, as determined by our Board, and subject to the applicable executive's continued employment through the payment date. Each employment agreement also provided the executive the ability to participate in our standard employee benefit plans.

If the employment of any executive is terminated by us without "cause" or by the executive for "good reason" (each, as defined in the applicable employment agreement), he will be entitled to receive (i) continued payments of base salary for 12 months following the date of termination and (ii) reimbursement for the cost of COBRA premiums for up to 12 months. These severance payments and benefits are subject to the executive's timely execution and non-revocation of a release of claims in our favor.

Each employment agreement includes a non-disclosure of confidential information provision, which applies indefinitely. The employment agreements for Messrs. Ball and Blue also include a non-competition provision and an employee and customer non-solicitation provision, both of which apply during employment and for either twelve months thereafter, in the event of a termination by us for "cause" or by the executive without

&nbsp;&nbsp;&nbsp;&nbsp;2026 Proxy Statement 28

"good reason," or six months thereafter, in the event of a termination by us without "cause" or by the executive for "good reason." The employment agreement for Mr. Points includes an employee and customer non-solicitation provision, which applies during employment and for twelve months thereafter.

Further, the employment agreement with Mr. Points provides that in the event any "parachute payments" (within the meaning of Section 280G of the Code) become payable to Mr. Points that are subject to excise taxes under Section 4999 of the Code, we will provide Mr. Points with an additional amount sufficient to cover any such taxes up to $500,000.

*Acceleration Policy*

We maintain a policy that provides stock options granted under our Amended and Restated Stock Option Plan (the "Stock Option Plan"), which was superseded by the 2025 Plan, will become fully vested and exercisable if the optionholder's employment is terminated by us without "cause" or by the optionholder for "good reason," in either case, within the period starting three months prior to, and ending 12 months after, a "change in control" (each, as defined in the policy). Pursuant to our Director Compensation Program, an eligible non-employee director's equity awards will vest in full immediately prior to a change of control (as defined in the Non-Employee Director Compensation Policy).

• each of our named executive officers;

• each of our current directors, and nominees for directors; and

• all of our current executive officers and directors as a group.

Under these rules, beneficial ownership includes any shares as to which the individual or entity has sole or shared voting power or investment power.

The percentage ownership is based on 20,727,949 shares of common stock outstanding as of the Record Date. In computing the number of shares beneficially owned by an individual or entity and the percentage ownership of that person, shares of common stock subject to stock options, warrants or other rights held by such person that are currently exercisable or will become exercisable within 60 days of the Record Date, or issuable pursuant to RSUs, which are subject to vesting and settlement conditions expected to occur within 60 days of the Record Date, are considered outstanding, although these shares are not considered outstanding for purposes of computing the percentage ownership of any other individual or entity. Unless otherwise indicated, the individual or entity identified in this table have sole voting and investment power with respect to all shares shown as beneficially owned by them, subject to applicable community property laws.

**ADDITIONAL INFORMATION**

**Stockholder Proposals to be Presented at the 2027 Annual Meeting of Stockholders**

For additional information on the requirements for submitting a proposal for consideration at the 2027 annual meeting of stockholders, please refer to the information contained in the "*When are stockholder proposals due for the 2027 annual meeting of stockholders?*" section of this Proxy Statement.

**Householding of Proxy Materials**

The SEC has adopted rules that permit companies and intermediaries (such as brokers) to implement a delivery procedure called "householding." Under this procedure, multiple stockholders who reside at the same address may receive a single copy of our Annual Report and proxy materials unless the affected stockholder has provided other instructions. This procedure reduces printing costs and postage fees, and helps protect the environment as well.

We expect that a number of brokers with account holders who are our stockholders will be "householding" our Annual Report and proxy materials. A single set of the Annual Report and other proxy materials will be delivered to multiple stockholders sharing an address unless contrary instructions have been received from one or more of the affected stockholders. Once you have received notice from your broker that it will be "householding" communications to your address, "householding" will continue until you are notified otherwise or until you revoke your consent. Stockholders may revoke their consent at any time by contacting their broker.

Upon written or oral request, we undertake to promptly deliver a separate copy of the Annual Report and other proxy materials to any stockholder at a shared address to which a single copy of any of those documents was delivered. To receive a separate copy of the Annual Report and other proxy materials now or in the future, you may write to our Corporate Secretary at Shoulder Innovations, Inc., 1535 Steele Avenue SW, Suite B, Grand Rapids, Michigan 49507 or call (616) 294-1026.

Any stockholders who share the same address and currently receive multiple copies of our Annual Report and other proxy materials who wish to receive only one copy in the future can contact their bank, broker or other holder of record to request information about "householding" or our Corporate Secretary at the address or telephone number listed above.

**Where You Can Find More Information**

We are subject to the informational requirements of the Exchange Act, and, in accordance therewith, file electronically with the SEC our annual, quarterly and current reports, proxy statements and other information. We make available on the Investor Relations page of our website at www.shoulderinnovations.com, free of charge, copies of these reports, as soon as reasonably practicable after we electronically file such material with, or furnish it to, the SEC. The SEC maintains a website that contains reports, proxy and information statements, and other information regarding issuers that file electronically with the SEC. The address of that website is www.sec.gov. The information in or accessible through any website referenced throughout this Proxy Statement is not incorporated into, and is not considered part of, this Proxy Statement.
