Important Notice Regarding the Availability of Proxy Materials for the Stockholder Meeting to be Held on May 31, 2024:

You are cordially invited to attend the meeting in person via live webcast. Whether or not you expect to attend the meeting, please complete, date, sign and return the proxy mailed to you, or vote over the telephone or the internet as instructed in these materials, as promptly as possible so that your shares may be voted in accordance with your wishes and in order that the presence of a quorum may be assured. Even if you have voted by proxy, you may still vote in person if you attend the meeting via live webcast. Please note, however, that if your shares are held of record by a broker, bank or other nominee and you wish to vote at the meeting, you must obtain a proxy issued in your name from that record holder. Your vote is important.

You may vote by proxy by completing and mailing the proxy card mailed to you. If you submit a proxy card, we will vote your shares as you direct. If you submit a proxy card without giving specific voting instructions for a particular proposal or nominee, those shares will be voted as recommended by our Board of Directors with respect to such proposal or nominee.

You may also vote by proxy via the Internet by going to the website www.proxyvote.com, and following the instructions provided there, or by telephone, by calling the following number: 1-800-690-6903 using a touch-tone phone and follow the recorded instructions. You will be asked to provide the control number found on the proxy card. Your proxy card, Internet or telephone vote must be received by 11:59 p.m., Eastern Time, on May 30, 2024, to be counted.

If your shares are held by a broker, bank, or other agent, you are considered the beneficial owner of those shares, and your shares are held in “street name.” If you hold your shares in “street name” you will receive instructions from your broker, bank or other agent describing how to vote your shares. If you hold shares in “street name” and do not receive instructions on how to vote your shares, you should contact your broker, bank or other agent promptly and request this information.

Even if you have voted by proxy via one of the procedures listed above, you may still vote in person if you attend the Annual Meeting via live webcast. Please note, however, that if your shares are held of record by a broker, bank or other agent and you wish to vote at the Annual Meeting, you must obtain a proxy issued in your name from that record holder.

The Notice also provides instructions on how to inform us whether to send future proxy materials to you electronically by e-mail or in printed form by mail. If you choose to receive future proxy materials by e-mail, you will receive an e-mail next year with instructions containing a link to those materials and a link to the proxy voting site. Your election to receive proxy materials by e-mail or printed form will remain in effect until you terminate or change it.

Choosing to receive future proxy materials by e-mail allows us to provide you with the information you need in a more timely manner, saves us the cost of printing and mailing documents to you, and conserves natural resources.

ELECTRONIC DELIVERY OF FUTURE PROXY MATERIALS

If you would like to reduce the costs incurred by Lumos Pharma, Inc. in mailing proxy materials, you can consent to receiving all future proxy statements, proxy cards and annual reports electronically via e-mail or the Internet. To sign up for electronic delivery, please follow the instructions above to vote using the Internet and, when prompted, indicate that you agree to receive or access proxy materials electronically in future years.

You should read this entire proxy statement carefully.

Our principal executive offices are located at 4200 Marathon Boulevard #200, Austin, Texas 78756.

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, or the SEC, we have elected to provide access to our proxy materials over the internet. Accordingly, we have sent you a Notice of Internet Availability of Proxy Materials, which we refer to as the Notice, because our Board is soliciting your proxy to vote at the Annual Meeting, 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 to 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 of the proxy materials are contained in the Notice.

We intend to mail the Notice to all stockholders of record entitled to vote at the Annual Meeting on or about April 15, 2024. In addition, stockholders may request to receive future proxy materials in printed form by mail or electronically by e-mail. A stockholder’s election to receive proxy materials by mail or e-mail will remain in effect until the stockholder terminates it.

How do I attend the Annual Meeting?

    The Annual Meeting will be held via live webcast at www.virtualshareholdermeeting.com/LUMO2024 on Friday, May 31, 2024 at 9:00 a.m., Central Time. You will be able to participate in the Annual Meeting, vote your shares electronically and submit your questions during the live webcast by entering your 16-digit control number found on the Notice. Information on how to vote at the Annual Meeting is discussed below.

Who can vote at the Annual Meeting?

    Only stockholders of record as of April 8, 2024 (the "Record Date") will be entitled to vote on matters brought before the Annual Meeting. On the Record Date, there were 8,116,488 shares of common stock outstanding and entitled to vote.

Stockholder of Record: Shares Registered in Your Name

    If on April 8, 2024 your shares were registered directly in your name with our transfer agent, Computershare Shareowner Services LLC, then you are a stockholder of record. As a stockholder of record, you may vote at the Annual Meeting or vote by proxy. Whether or not you plan to attend the meeting, we urge you to vote by proxy over the telephone or on the internet as instructed below, or to fill out and return a proxy card that you may request or that we may elect to deliver at a later time, to ensure your vote is counted.

1

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

    If on April 8, 2024 your shares were held, not in your name, but rather in an account at a brokerage firm, bank, dealer 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 or other agent regarding how to vote the shares in your account in accordance with the instructions you have received from your brokerage firm, bank, dealer or other similar organization. You are also invited to attend the meeting via live webcast. However, since you are not the stockholder of record, you may not vote your shares at the Annual Meeting unless you request and obtain a valid proxy from your broker or other agent.

What am I voting on?

There are four matters scheduled for a vote:

1.Election of the Board of Directors’ nominees for director, Chad A. Johnson and Lota S. Zoth, to serve until the 2027 Annual Meeting of Stockholders;

2.Advisory approval of the compensation of our named executive officers, as disclosed in this proxy statementin accordance with SEC rules;

3.Advisory selection of the frequency period to hold the advisory vote regarding the approval of the compensation of our named executive officers; and

4.Ratification of the selection, by the Audit Committee of our Board, of KPMG LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2024.

What if another matter is properly brought before the meeting?

    We know of no other matters that will be presented for consideration at the Annual Meeting. If any other matters are properly brought before the meeting, it is the intention of the persons named in the accompanying proxy to vote on those matters in accordance with their best judgment.

How do I vote?

    With respect to Proposal No. 1 (Election of Directors), you may either vote “For” all the nominees to our Board or you may “Withhold” your vote for any nominee you specify. With respect to Proposal No. 3 (Frequency of Compensation Vote), you may either select a frequency period of "One Year," "Two Years" or "Three Years" or abstain from voting. For each of the other matters to be voted on, you may vote “For” or “Against” or abstain from voting.

The procedures for voting are:

Stockholder of Record: Shares Registered in Your Name

    If you are a stockholder of record, you may vote at the Annual Meeting, vote by proxy over the telephone, vote by proxy through the internet, or vote by proxy using a proxy card that you may request or that we may elect to deliver at a later time. Whether or not you plan to attend the meeting, we urge you to vote by proxy to ensure that your vote is counted. You may still attend the meeting and vote even if you have already voted by proxy.

•To vote at the Annual Meeting, visit the following website: www.virtualshareholdermeeting.com/LUMO2024. You will be able to participate in the Annual Meeting, vote your shares electronically and submit your questions during the live webcast by entering your 16-digit control number found on the voting form provided.

•To vote using a proxy card, simply complete, sign and date the proxy card that may be delivered to you and return it promptly in the envelope provided. If you return your signed proxy card to us before the meeting, we will vote your shares as you direct.

•To vote over the telephone, dial toll-free 1-800-690-6903 using a touch-tone phone and follow the recorded instructions. You will be asked to provide the company number and control number from the Notice.

•To vote through the internet, go to www.proxyvote.com to complete an electronic proxy card. You will be asked to provide the control number from the Notice.

Your proxy, telephone or internet vote must be received by 11:59 p.m., Eastern Time, on May 30, 2024 to be counted.

2

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

    If you are a beneficial owner of shares registered in the name of your broker, bank, or other agent, you should have received a Notice containing voting instructions from that organization rather than from us. Simply follow the voting instructions in the Notice to ensure that your vote is counted. To vote in person at the Annual Meeting via live webcast, you must obtain a valid proxy from your broker, bank or other agent. Follow the instructions from your broker or bank included with these proxy materials, or contact your broker or bank to request a proxy form.

Internet proxy voting may be provided to allow you to vote your shares online, with procedures designed to ensure the authenticity and correctness of your proxy vote instructions. However, please be aware that you must bear any costs associated with your internet access, such as usage charges from internet access providers and telephone companies.

How many votes do I have?

    On each matter to be voted upon, you have one vote for each share of common stock you own as of April 8, 2024. Common stock is the only class of voting securities currently outstanding and entitled to vote.

What happens if I do not vote?

Stockholder of Record: Shares Registered in Your Name

If you are a stockholder of record and do not vote (1) by completing and returning your proxy card, (2) by telephone, (3) through the internetor (4) in person at the Annual Meeting via live webcast, your shares will not be voted.

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

    If you are a beneficial owner and do not instruct your broker, bank, or other agent how to vote your shares, the question of whether your broker or nominee will still be able to vote your shares depends on whether the New York Stock Exchange (NYSE) deems the particular proposal to be a “routine” matter. Brokers and nominees can use their discretion to vote “uninstructed” shares with respect to matters that are considered to be “routine,” but not with respect to “non-routine” matters. Under the rules and interpretations of the New York Stock Exchange, “non-routine” matters are matters that may substantially affect the rights or privileges of stockholders, such as mergers, stockholder proposals, elections of directors (even if not contested), executive compensation (including any advisory stockholder votes on executive compensation and on the frequency of stockholder votes on executive compensation), and certain corporate governance proposals, even if management-supported. These rules apply to brokers holding our shares even though our common stock is traded on the NASDAQ Global Market. Accordingly, your broker or nominee may not vote your shares on Proposal No. 1 (Election of Directors), Proposal No. 2 (Advisory Vote on Compensation of Our Named Executive Officers), or Proposal No. 3 (Frequency of Compensation Vote) but may vote your shares on Proposal No. 4 (Ratification of Selection of KPMG LLP as Our Independent Registered Public Accounting Firm) even in the absence of your instruction.

What if I return a proxy card or otherwise vote but do not make specific choices?

    If you return a signed and dated proxy card or otherwise vote without marking voting selections, your shares will be voted, as applicable, “For” the election of the nominees for director, “For” the advisory approval of executive compensation, "One Year" for the frequency of future advisory votes on executive compensation, and “For” ratification of the selection, by the Audit Committee of our Board, of KPMG LLP as our independent registered public accounting firm for our fiscal year ending December 31, 2024. If any other matter is properly presented at the meeting, your proxyholder (one of the individuals named on your proxy card) will vote your shares using his or her best judgment.

3

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 agents 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. For example, you may own some shares directly as a stockholder of record and other shares through a broker, or you may own shares through more than one broker. Please follow the voting instructions on each Notice 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 Annual 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 the Company’s Secretary at 4200 Marathon Boulevard #200, Austin, TX 78756; or

•You may attend the Annual Meeting and vote in person via live webcast (simply attending the meeting will not, by itself, revoke your proxy).

    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 or bank as a nominee or agent, you should follow the instructions provided by your broker or bank.

When are stockholder proposals due for next year’s annual meeting?

    In accordance with Rule 14a-8 of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), to be considered for inclusion in next year’s proxy materials, your proposal must be submitted in writing and received by December 13, 2024 to Corporate Secretary, Lumos Pharma, Inc., 4200 Marathon Boulevard #200, Austin, TX 78756.If you wish to submit a director nomination or a proposal at next year’s annual meeting that is not to be included in next year’s proxy materials, you must do so by no later than the close of business on March 2, 2025, nor earlier than the close of business on January 31, 2025 and you must comply with the requirements of Section 5(b) in our amended and restated bylaws ("Bylaws"), including submitting written notice to our Corporate Secretary as set forth above. However, if the date of next year’s annual meeting is more than 30 days before or more than 30 days after May 31, 2025, then we must receive your notice no earlier than the close of business on the one hundred twentieth (120th) day prior to such meeting and no later than the close of business on the later of the ninetieth (90th) day prior to such meeting or the tenth (10th) day following the day on which public announcement of the date of such meeting is first made.

If you intend to solicit proxies in support of director nominees other than the Company’s nominees, then we must receive notice providing the information required by Rule 14a-19 of the Exchange Act, postmarked no later than April 1, 2025. However, if the date of next year’s annual meeting is more than 30 days before or more than 30 days after May 31, 2025, then we must receive your notice by the close of business on the later of the sixtieth (60th) day prior to such meeting or the tenth (10th) day following the day on which public announcement of the date of such meeting is first made.

You are also advised to review our Bylaws, which contain additional requirements regarding advance notice of stockholder proposals and director nominations.

4

What happens if I do not provide instructions on how to vote or if other matters are presented for determination at the Annual Meeting?

    If you are a stockholder of record and return your proxy card without instructions, the persons named as proxy holders on the proxy card will vote in accordance with the recommendations of the Board of Directors.

    If you are a beneficial owner as noted above you generally cannot vote your shares directly and must instead instruct your broker, trustee, bank or nominee how to vote your shares using the voting instructions form provided by that intermediary. If you do not provide voting instructions, whether your shares can be voted by your broker, bank or nominee depends on the type of item being considered.

•Non-Discretionary Items. If you do not provide voting instructions for any of the non-discretionary items at the Annual Meeting, your broker, bank or nominee cannot vote your shares, resulting in a “broker non-vote.” All items of business other than Proposal No. 4 (Ratification of Selection of KPMG LLP as Our Independent Registered Public Accounting Firm) are non-discretionary items. Shares constituting broker non-votes will be counted as present for the purpose of determining a quorum at the Annual Meeting, but generally are not counted or deemed to be present in person or by proxy for the purpose of voting on any of the non-discretionary items.

•Discretionary Items. Even if you do not provide voting instructions, your broker, bank or nominee may vote in its discretion on Proposal No. 4 (Ratification of Selection of KPMG LLP as Our Independent Registered Public Accounting Firm) because it is a discretionary item.

What items are being voted upon, how does the Board recommend that you vote, and what are the standards for determining whether an item has been approved?

Proposal Number	Proposal Description	Board Recommendation	Vote Required for Approval	Effect of Abstentions	Effect of Broker Non-Vote
1	Election of Directors	FOR each director nominee	Nominees receiving the most “For” votes	No effect	None
2	Advisory Vote on Compensation of Our Named Executive Officers	FOR	“For” votes from a majority of shares present in person or represented by proxy and entitled to vote on the matter	Against	None
3	Advisory Vote on Frequency of Future Advisory Votes on Compensation of Our Named Executive Officers	ONE YEAR	Frequency period receiving the most votes	No effect	None
4	Ratification of Selection of KPMG LLP as Our Independent Registered Public Accounting Firm	FOR	“For” votes from a majority of shares present in person or represented by proxy and entitled to vote on the matter	Against	Not applicable

What is the quorum requirement?

    A quorum of stockholders is necessary to hold a valid meeting. A quorum will be present if stockholdersholdinga majority of the outstanding shares entitled to vote are present in person via live webcast or represented by proxy. On the Record Date, there were 8,116,488sharesoutstanding and entitled to vote. Thus, the holders of 4,058,245 shares must be present at the meeting or represented by proxy at the meeting to have a quorum.

    Your shares will be counted toward the quorum only if you submit a valid proxy (or one is submitted on your behalf by your broker, bank or other nominee) or if you vote in person via live webcast at the meeting. Abstentions and broker non-votes will be counted towards the quorum requirement. If there is no quorum, the holders of a majority of shares represented at the meeting may adjourn the meeting to another date.

5

How can I find out the results of the voting at the annual meeting?

    Preliminary voting results will be announced at the Annual Meeting. In addition, final voting results will be published in a current report on Form 8-K that we expect to file within four business days after the Annual Meeting. If final voting results are not available to us in time to file a Form 8-K within four business days after the Annual Meeting, we intend to file a Form 8-K to publish preliminary results and, within four business days after the final results are known to us, file an additional Form 8-K to publish the final results.

PROPOSAL 1

ELECTION OF DIRECTORS

    Our Board 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 our Board may be filled only by persons elected by a majority of the remaining directors. A director elected by our Board 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 presently has seven members. There are two directors in the class whose term of office expires in 2024, each of whom has been nominated for re-election. Chad A. Johnson currently serves on our Board and was previously elected by the stockholders in 2021. Lota S. Zoth currently serves on our Board and was previously elected by the stockholders in 2021. If elected at the Annual Meeting, each nominee would serve until the 2027 Annual Meeting of Stockholders and until such person's successor has been duly elected and qualified, or, if sooner, until the director’s death, resignation or removal.

    Directors are elected by a plurality of the votes of the holders of shares present in person at the Annual Meeting or represented by proxy and entitled to vote on the election of directors. If a choice is specified on the proxy card by a stockholder, their shares will be voted as specified. If a choice is not specified on the proxy card, and authority to do so is not withheld, the shares will be voted “FOR” the election of nominees named below. Shares represented by executed proxies will be voted, if authority to do so is not withheld, for the election of the nominees named below. If any nominee becomes unavailable for election as a result of an unexpected occurrence, shares that would have been voted for that nominee will instead be voted for the election of a substitute nominee proposed by us. Each person nominated for election has agreed to serve if elected. Our management has no reason to believe that any nominee will be unable to serve.

Class III Director Nominees

    Below is a brief biography of each nominee and each director whose term will continue after the Annual Meeting, including the ages of each nominee and director as of April 1, 2024. Each individual listed below is nominated for election for a three-year term expiring at the 2027 Annual Meeting.

INFORMATION REGARDING OUR BOARD OF DIRECTORS AND CORPORATE GOVERNANCE

Independence of our Board of Directors

    In determining independence, our Board considers the definition of “independent” set forth in the listing standards of the NASDAQ Stock Market, or NASDAQ, as well as other factors that contribute to effective oversight and decision-making by our Board. Our independence standards are set forth in our Corporate Governance Guidelines on our website at www.lumos-pharma.com in the “Investors & Media - Corporate Governance” section. As required under the NASDAQ listing standards, a majority of the members of a listed company’s board of directors must qualify as “independent,” as affirmatively determined by our Board. Our Board consults with our counsel to ensure that our Board’s 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 our Company, its senior management and its independent auditors, our Board has affirmatively determined that the following directors are independent directors within the meaning of the applicable NASDAQ listing standards: Dr. van Es-Johansson, Mr. Johnson, Mr. Lalande, Dr. McCracken, Dr. Raffin and Ms. Zoth. In making its independence assessments, our Board found that none of these directors or nominees for director had a material or other disqualifying relationship with our Company.

    Mr. Hawkins is not an independent director by virtue of his employment with our Company.

    There are no family relationships among any of our directors, director nominees and executive officers.

Board Leadership

    Our Board is currently chaired by our Chief Executive Officer, Mr. Hawkins. Our Board has appointed Dr. Raffin as Lead Independent Director.

    We believe that combining the positions of Chief Executive Officer and Chair of our Board, which we refer to as the Chair, helps to ensure that our Board and management act with a common purpose. We believe combining the positions of Chief Executive Officer and Chair is appropriate for a biopharmaceutical company focused on drug development in that it enhances our Board’s focus on our progress on scientific research, clinical trials and commercialization as inputs to developing and implementing strategy. We believe that combining the positions of Chief Executive Officer and Chair provides a single, clear chain of command to execute our strategic initiatives and business plans related to drug development and commercialization. In addition, we believe that a combined Chief Executive Officer and Chair is well-positioned to act as a bridge between management and our Board, facilitating the regular flow of information. We also believe that it is advantageous to have a Chair with an extensive history with and knowledge of our Company (as is the case with our Chief Executive Officer) as compared to a relatively less informed independent Chair at this stage in our development.

    Our Board appointed Dr. Raffin as the Lead Independent Director to help reinforce the independence of our Board as a whole. The position of Lead Independent Director has been structured to serve as an effective balance to a combined Chief Executive Officer and Chair. The Lead Independent Director is empowered, among other duties and responsibilities, to develop, together with the Chief Executive Officer, the agenda for meetings of our Board, to develop, together with committee chairs, the agendas for meetings of committees, to preside over Board meetings in the absence of the officers and to oversee our Board’s annual evaluation of the Chief Executive Officer’s performance.

11

Role of Our Board of Directors on Risk Oversight

    One of our Board’s key functions is informed oversight of our risk management process. 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 Board standing committees that address risks inherent in their respective areas of oversight. In particular, while our Board is responsible for monitoring and assessing strategic risk exposure, our Audit Committee has the responsibility to consider and discuss the major financial risk exposures and the steps management has taken to monitor and control these exposures, including guidelines and policies to govern the process by which risk assessment and management is undertaken. Our Audit Committee also monitors compliance with legal and regulatory requirements with respect to SEC regulations, NASDAQ listing standards, pharmaceutical industry regulations and corporate risk management, in addition to oversight of the performance of our accounting and financial reporting processes. Our Nominating and Corporate Governance Committee monitors the effectiveness of the corporate governance guidelines, including whether they are successful in preventing illegal or improper liability-creating conduct, and is responsible for overseeing our cybersecurity risk management processes. Our Compensation Committee assesses and monitors whether any compensation policies and programs have the potential to encourage excessive risk-taking. The entire Board and its committees address risk management issues from time-to-time and meet at least annually with the employees responsible for risk management in the committees’ respective areas of oversight. Both our Board as a whole and the various standing committees receive periodic reports from the employees responsible for risk management, as well as incidental reports as matters may arise. It is the responsibility of the committee chairs to report findings regarding material risk exposures to our Board as quickly as possible.

Meeting Attendance

    Our Board met seven times during the fiscal year ended December 31, 2023. Our Audit Committee met four times during the 2023 fiscal year, our Compensation Committee met five times during the 2023 fiscal year, and our Nominating and Corporate Governance Committee met four times during the 2023 fiscal year. None of our incumbent directors attended fewer than 75% of the meetings of the Board and committee meetings of which he or she was a member.

    It is our policy to encourage directors and nominees for director to attend the Annual Meeting. Each of our directors attended our virtual 2023 Annual Meeting of Stockholders.

Committees of our Board of Directors

    The following table sets forth the current membership of each of our Audit Committee, Compensation Committee and Nominating and Corporate Governance Committee:

Name	Audit	Compensation	Nominating and Corporate Governance
An van Es-Johansson, M.D.			X
Chad A. Johnson	X		Chair
Kevin Lalande		X
Joseph McCracken	X
Thomas A. Raffin, M.D.		Chair	X
Lota S. Zoth	Chair	X

Each of the committees has authority to engage legal counsel or other experts or consultants, as it deems appropriate to carry out its responsibilities. Our Board has determined that, except as specifically described below,each current member of each committee meets the applicable NASDAQ rules and regulations regarding “independence” and that each member is free of any relationship that would impair his or her individual exercise of independent judgment with regard to the Company.

12

Board Diversity

We value diverse perspectives and believe different points of view brought through diverse representation lead to better business performance, decision making and understanding. Our Board takes a multi-dimensional approach to diversity. In addition to industry expertise and professional experience, our Board values representation that reflects diversity in other important categories including gender, race/ethnicity and sexual orientation.

The matrix below summarizes our current board composition:

Board Diversity Matrix (As of March 31, 2024)
Board Size:
Total Number of Directors	7
Gender	Male	Female
Number of directors based on gender identity	5	2

White	5	2

    Below is a description of each committee of our Board.

Audit Committee

    Our Audit Committee was established by our Board in accordance with Section 3(a)(58)(A) of the Exchange Act to oversee our corporate accounting and financial reporting processes and audits of our financial statements. For this purpose, our Audit Committee performs several functions. Our Audit Committee evaluates the performance of and assesses the qualifications of the independent auditors; determines and approves the engagement of the independent auditors; determines whether to retain or terminate the existing independent auditors or to appoint and engage new independent auditors; reviews and approves the retention of the independent auditors to perform any proposed permissible non-audit services; monitors the rotation of partners of the independent auditors on our audit engagement team as required by law; confers with management and the independent auditors regarding the effectiveness of internal controls over financial reporting; establishes procedures, as required under applicable law, for the receipt, retention and treatment of complaints received by the Company regarding accounting, internal accounting controls or auditing matters and the confidential and anonymous submission by employees of concerns regarding questionable accounting or auditing matters, oversees corporate risk management of the company as a whole; and meets to review our annual audited financial statements and quarterly financial statements with management and the independent auditor, including a review of our disclosures in our Annual Report on Form 10-K under the heading “Management’s Discussion and Analysis of Financial Condition and Results of Operations.”

    Our Audit Committee is currently comprised of three directors: Ms. Zoth, Mr. Johnson and Dr. McCracken. Our Board has adopted a written Audit Committee charter that is available to stockholders on our website at www.lumos-pharma.com in the “Investors & Media - Corporate Governance” section.

    Our Board reviews the NASDAQ listing standards definition of independence for Audit Committee members on an annual basis and has determined that each current member of our Audit Committee meets the independence requirement (as independence is currently defined in Rule 5605(c)(2)(A)(i) and (ii) of the NASDAQ listing standards).

    Our Board has also determined that Ms. Zoth qualifies as an “audit committee financial expert,” as defined in applicable SEC rules. Our Board made a qualitative assessment of Ms. Zoth’s level of knowledge and experience based on a number of factors, including her formal education and her years of experience.

Compensation Committee

    The Compensation Committee of our Board is currently comprised of three directors: Dr. Raffin, Mr. Lalande, and Ms. Zoth. All current members of our Compensation Committee are independent (as independence is currently defined in Rule 5605(d)(2) of the NASDAQ listing standards). Additionally, all current members of our Compensation Committee are non-employee directors under Rule 16b-3 of the Exchange Act. Our Board has adopted a written Compensation Committee charter

13

that is available to stockholders on our website at www.lumos-pharma.com in the “Investors & Media - Corporate Governance” section.

    The 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 directors, executive officers and other senior management. The scope of authority and specific responsibilities of our Compensation Committee include:

•determining the compensation and other terms of employment of our executive officers and reviewing and approving corporate performance goals and objectives relevant to such compensation;

•evaluating and recommending to our Board the compensation plans and programs advisable for the Company, and evaluating and recommending the modification or termination of existing plans and programs;

•reviewing and approving the terms of any employment agreements, severance arrangements, change in control protections and any other compensatory arrangements for our executive officers;

•selecting, retaining and terminating compensation consultants to assist in its evaluation of executive and director compensation, including the sole authority to approve the consultant’s reasonable fees and other retention terms; and

•reviewing and recommending to our Board the type and amount of compensation to be paid or awarded to members of our Board.

For fiscal year 2023, our Compensation Committee retained Setren & Associates, Inc. ("Setren & Associates"), as its independent compensation consultant to advise on various aspects of executive compensation and our overall equity practices. Setren & Associates was retained by and reported directly to our Compensation Committee. Setren & Associates did not provide any other consulting services to our Company.

Annually, our Compensation Committee has considered the following six factors, as set forth by the SEC and NASDAQ, when engaging Setren & Associates and evaluating its independence: (i) the provision of other services to our Company by Setren & Associates; (ii) the amount of fees from our Company paid to Setren & Associates as a percentage of Setren & Associates' total revenue; (iii) Setren & Associates' policies and procedures that are designed to prevent conflicts of interest; (iv) any business or personal relationship of Setren & Associates with an executive officer of our Company; (v) any business or personal relationship of the individual compensation advisor with any member of our Compensation Committee; and (vi) any stock of our Company owned by Setren & Associates. Based on its review, our Compensation Committee has determined that the work of Setren & Associates has not raised any conflict of interest that would adversely affect Setren & Associates' independence.

Nominating and Corporate Governance Committee

    Our Nominating and Corporate Governance Committee of our Board is responsible for overseeing our corporate governance functions on behalf of our Board, making recommendations to our Board regarding corporate governance issues, identifying, reviewing and evaluating candidates to serve as directors of the Company consistent with criteria approved by our Board, reviewing and evaluating incumbent directors, recommending to our Board for selection candidates for election to our Board and making other recommendations to our Board regarding affairs relating to the directors of the Company, including director compensation.

    Our Nominating and Corporate Governance Committee is currently comprised of three directors: Mr. Johnson, Dr. van Es-Johansson and Dr. Raffin. All current members of our Nominating and Corporate Governance Committee are independent (as independence is currently defined in Rule 5605(a)(2) of the NASDAQ listing standards). Our Board has adopted a written Nominating and Corporate Governance Committee charter that is available to stockholders on our website at www.lumos-pharma.com in the “Investors & Media - Corporate Governance” section.

    Our Nominating and Corporate Governance Committee believes that candidates for director 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. Our Nominating and Corporate Governance Committee also considers whether the candidate possesses the following factors among others: relevant expertise upon which to base advice and guidance to management, sufficient time to devote to the affairs of the Company, demonstrated excellence in his or her field, the ability to exercise sound business judgment and the commitment to rigorously represent the long-term interests of our stockholders. Candidates for director nominees are reviewed in the context of the current composition of our Board, the operating requirements of the Company and the long-term interests of stockholders. In conducting this assessment, our Nominating and Corporate Governance Committee typically considers diversity, age, skills and such other factors as it deems appropriate given the current needs of our Board and the Company to maintain a balance of knowledge, experience and capability. Our

14

Nominating and Corporate Governance Committee does not have a policy regarding how it considers diversity in selecting candidates.

    In the case of incumbent directors whose terms of office are set to expire, our Nominating and Corporate Governance 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 relationships and transactions that might impair the directors’ independence. Our Nominating and Corporate Governance Committee also takes into account the results of our Board’s self-evaluation, conducted annually on a group and individual basis. In the case of new director candidates, our Nominating and Corporate Governance Committee also determines whether the nominee is independent for NASDAQ purposes, which determination is based upon applicable NASDAQ listing standards, applicable SEC rules and regulations and the advice of counsel, if necessary. Our Nominating and Corporate Governance Committee then uses its network of contacts to compile a list of potential candidates, but may also engage, if it deems appropriate, a professional search firm. Our Nominating and Corporate Governance Committee conducts any appropriate and necessary inquiries into the backgrounds and qualifications of possible candidates after considering the function and needs of our Board. Our Nominating and Corporate Governance Committee meets to discuss and consider the candidates’ qualifications and then selects a nominee for recommendation to our Board by majority vote.

    In identifying potential candidates for Board membership, our Nominating and Corporate Governance Committee relies on suggestions and recommendations from our Board, stockholders, management and others. Our Nominating and Corporate Governance Committee will consider director candidates recommended by stockholders that are properly and timely submitted by stockholders in accordance with our policies and Bylaws. Our Nominating and Corporate Governance Committee does not intend to alter the manner in which it evaluates candidates, including the minimum criteria set forth above based on whether or not the candidate was recommended by a stockholder.

Code of Business Conduct and Ethics

    The Company has adopted its Code of Business Conduct and Ethics that applies to all officers, directors and employees. The Code of Business Conduct and Ethics is available on our website at www.lumos-pharma.com in the “Investors & Media - Corporate Governance” section. Any future amendments or waivers to our code of ethics will be promptly disclosed on our website and as required by applicable laws, rules and regulations of the SEC and NASDAQ.

Corporate Governance Guidelines

Our Board adopted Corporate Governance Guidelines to assure that our Board will have the necessary authority and practices 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 our Board intends to follow with respect to board composition and selection, board meetings and involvement of senior management, Chief Executive Officer performance evaluation and succession planning and board committees and compensation. The Corporate Governance Guidelines, as well as the charters for each committee of our Board, may be viewed at www.lumos-pharma.com in the “Investors & Media - Corporate Governance” section.

Executive Sessions of Independent Directors

To encourage and enhance communication among independent directors, and as required under applicable Nasdaq rules, our Corporate Governance Guidelines provide that the independent directors meet in executive sessions without management directors or management present on a periodic basis, no less than four times per year. These executive sessions are chaired by Dr. Raffin as Lead Independent Director.

PROPOSAL 2

ADVISORY VOTE ON COMPENSATION OF OUR NAMED EXECUTIVE OFFICERS

At the 2018 Annual Meeting of Stockholders, our stockholders indicated their preference that the Company solicit a non-binding advisory vote on the compensation of the named executive officers, commonly referred to as a “say-on-pay vote,” every year. Our Board has adopted a policy that is consistent with that preference.

This vote is being provided pursuant to Section 14A of the Exchange Act. It 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, the Company believes that its compensation policies and decisions are consistent with our strategic compensation and retention needs. Further, our compensation policies and decisions are designed to align our executive officers’ compensation with our business objectives and the interests of its stockholders, to incentivize and reward our executive officers for our success and to promote teamwork within our executive management team. Compensation of our named executive officers is designed to enable the Company to attract and retain talented and experienced executives to lead the Company successfully in a competitive environment.

Accordingly, our Board is asking the 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 our Board or our Company. Nevertheless, the views expressed by the stockholders, whether through this vote or otherwise, are important to management and our Board and, accordingly, our Board and our Compensation Committee intend to consider the results of this vote in making determinations in the future regarding executive compensation arrangements.

Advisory approval of this proposal requires the affirmative vote of the majority of shares present in person or represented by proxy at the Annual Meeting and entitled to vote generally on the subject matter. Abstentions will be counted toward the tabulation of votes on proposals presented to the stockholders and will have the same effect as negative votes. Broker non-votes are counted toward a quorum but are not counted for any purpose in determining whether this matter has been approved.

Unless our Board decides to modify its policy regarding the frequency of soliciting advisory votes on the compensation of our named executive officers, the next scheduled say-on-pay vote will be at the 2025 Annual Meeting of Stockholders.

OUR BOARD OF DIRECTORS RECOMMENDS A VOTE IN FAVOR OF PROPOSAL 2.

16

PROPOSAL 3

ADVISORY VOTE ON THE FREQUENCY OF FUTURE ADVISORY VOTES ON THE COMPENSATION OF OUR NAMED EXECUTIVE OFFICERS

The Dodd-Frank Act enables our stockholders to indicate how frequently they believe we should seek a non-binding advisory vote from our stockholders on the compensation of our named executive officers, i.e., how frequently to request future “Say-on-Pay” votes from stockholders. We are accordingly seeking a non-binding, advisory vote from stockholders as to the frequency with which our stockholders should have an opportunity to provide an advisory approval of our named executive officer compensation. We are providing our stockholders with the choice of selecting a frequency of one year, two years or three years, or abstaining from this advisory vote. The alternative of every one year, two years, or three years that receives the highest number of votes cast by stockholders in person or by proxy at this meeting will be considered to be the preferred frequency that has been recommended by our stockholders.

The vote on this proposal is advisory; therefore, it is not binding on the Company, our Board or our Compensation Committee. We may determine in the future that it is in the best interests of the Company and our stockholders to hold Say-on-Pay votes more or less frequently than the frequency indicated by stockholders in voting on this proposal or as currently recommended by our Board. However, we plan to consider the results of the vote on this proposal in determining the frequency of our Say-on-Pay votes because we value the opinions of our stockholders.

Currently, we believe that it is in the best interests of the Company and our stockholders to hold a Say-on-Pay vote every year, and this is the frequency recommended by our Board. We believe this frequency will enable our stockholders to vote, on a non-binding, advisory basis, on our most recent executive compensation practices and decisions as presented in our annual proxy statements, which will lead to greater transparency and more meaningful and timely communication between us and our stockholders regarding the compensation of our named executive officers.

Accordingly, we recommend that our stockholders indicate a preferred voting frequency period of “One Year” in response to the following non-binding advisory resolution:

“RESOLVED, that the alternative of every one year, two years, or three years that receives the highest number of votes cast by stockholders in person or by proxy at this meeting will be considered to be the preferred frequency with which the Company is to hold an advisory vote on the compensation of the Company’s named executive officers.”

OUR BOARD OF DIRECTORS RECOMMENDS THAT STOCKHOLDERS VOTE FOR THE OPTION OF ONE YEAR AS THE PREFERRED FREQUENCY PERIOD.

PROPOSAL 4

RATIFICATION OF SELECTION OF KPMG LLP AS INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

    Our Audit Committee has selected KPMG LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2024 and has further directed that management submit the selection of independent registered public accounting firm for ratification by the stockholders at the Annual Meeting. KPMG LLP has audited our financial statements since 1999. From 2015 through the Merger, KPMG LLP audited Private Lumos' financial statements. Representatives of KPMG LLP are expected to be available 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 nor other governing documents or law require stockholder ratification of the selection of KPMG LLP as our independent registered public accounting firm. However, our Audit Committee is submitting the selection of KPMG LLP to the stockholders for ratification as a matter of good corporate practice. If the stockholders fail to ratify the selection, our Audit Committee will reconsider whether or not to retain that firm. Even if the selection is ratified, our Audit Committee 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 our Company and our stockholders.

    The affirmative vote of the majority of shares present or represented by proxy at the Annual Meeting and entitled to vote generally on the subject matter will be required to ratify the selection of KPMG LLP.Abstentions will be counted toward the tabulation of votes on proposals presented to the stockholders and will have the same effect as negative votes. Broker non-votes are counted towards a quorum but are not counted for any purpose in determining whether this matter has been approved.

The pre-approval of services has been delegated to the Chair of our Audit Committee, but the decision must be reported to the full Audit Committee at its next scheduled meeting.

In connection with the audit of the 2023 financial statements, our Audit Committee entered into an engagement agreement with KPMG LLP that sets forth the terms by which KPMG LLP was to perform audit services for the Company.

Narrative Disclosure to Summary Compensation Table

    Our executive compensation program consists of three primary components: base salary, short-term incentives, and long-term equity incentives.

Base Salary

Base salary is the primary fixed element of our executive compensation program. We use base salary to compensate our executive officers for services rendered during the fiscal year, and to ensure that we remain competitive in attracting and retaining executive talent.

Upon joining us, each of our executive officers, received an offer letter that provided for an initial base salary. These initial base salaries are the product of negotiation with the executive, but we generally seek to establish salaries that we believe are commensurate with the salaries paid to industry peers with comparable qualifications, experience, responsibilities and performance at similar companies. Our Compensation Committee has also relied on its members’ collective experience in the marketplace for determining what they believe to be the market rate of salaries for executives of comparable companies.

Historically, we have not applied, nor do we intend to apply, specific formulas to determine base salary increases. Instead, we annually review corporate and individual performance. Our Compensation Committee examines numerous factors, including the executive’s expertise, seniority, position, functional role, level of responsibility and individual performance

26

during the previous year. Further, our Compensation Committee reviews peer and market data as provided by Setren & Associates.

Short-Term Cash Incentives

Our performance-based cash incentives are designed to provide executive officers with the opportunity to earn annual cash awards based upon the achievement of pre-specified corporate and individual performance objectives which align with and support our business strategy.

Shortly before the end of each fiscal year, our Board determines the annual target bonus percentages for our executive officers for the upcoming fiscal year based on the recommendations of our Compensation Committee. Generally, each executive officer is eligible for a discretionary annual cash incentive payment up to a specified percentage of the executive officer’s salary. Our Board sets these annual target bonus percentages at levels that, upon achievement of the target percentage, are likely to result in cash bonus payments that our Board believes to be approximately the level paid to high-performing executives of comparable companies in the biopharmaceutical industry.

For 2023, based upon recommendations of our Compensation Committee with the assistance of Setren & Associates, our Board maintained target bonus amounts for Mr. Hawkins, Mr. McKew and Ms. Lawley equal to 55%, 50% and 40% of their respective base salaries. Our Board reserved the ability to grant bonuses in excess of the executives’ target bonus percentages for extraordinary performance.

2023 Performance Objectives

The performance goals for each fiscal year are determined by the Board in the first quarter of each fiscal year, and typically include corporate and individual performance objectives which are tailored to each executive’s role and responsibilities.

For 2023, the Company had the following corporate goals:

Metric	Weight
Clinical: •100% enrollment of randomized patients in OraGrowtH210 by end of Q2 and deliver top-line six month data by year end (15%) •OraGrowtH210 Trial six month AHV analysis from up to 24 subjects by year end (15%) •Bioavailability trial initiated by year end (10%)	40%
CMC: •Drug products shipped and available at clinical site by Q4 2023 for relative bioavailability and other studies (10%) •Complete tech-transfer of drug substance manufacturing process and stability study initiation of 10 kg and 25 kg scale by state of Q4 2023 (5%) •Completion of analytical, quality and manufacturing process related factors for Phase 3 drug product manufacture readiness by end of Q2 2023 (5%)	20%
Finance: •Secure financing through a combination of strategic transaction, regional license deal(s), financial sources and/or operational improvements to extend cash runway by an additional 6 to 12 months with Board approval	30%
R&D and Business Development: •Successful negotiation of the license agreement and go/no-go decision by Board by the end of the year and generate scale up and pharmacology data necessary for final decision on option deal	10%

At the end of the fiscal year, our Compensation Committee assesses the accomplishments of each executive versus each of the aforementioned goals and recommends earned bonus amounts to the Board for approval. The Compensation Committee retains the ability to apply discretion to adjust bonus amounts higher or lower based on other corporate performance factors.

27

2023 Earned Bonuses

For 2023, the Compensation Committee continued to take a two-tiered approach at determining the amount of earned bonus for each executive based on the current company conditions as well as actual performance. First, the Compensation Committee looked at the performance of each executive against each of the stated performance goals. Secondly, in light of current events and biotech industry conditions as a whole, the Compensation Committee determined it to be in the best interests of the company and its stockholders to use the bonus earning as a retention device in efforts to retain key personnel. Additionally, the Compensation Committee, at its discretion, determined that Dr. McKew should receive a supplemental bonus because he provided contributions to the Company that are expected to increase stockholder value. Dr. McKew's contributions include extensive leadership during the analysis and reporting of our top line data analysis for our OraGrowtH210 and OraGrowtH212 Trials, as well as considerable contributions and guidance throughout the process of acquiring patent protection for a novel formulation of LUM-201 to extend exclusivity to 2042.

For 2023, the Compensation Committee determined that performance with respect to the stated goals would result in a 70% payout, and bonuses were paid accordingly.

Final bonus payouts for 2023 performance were as follows:

Executive	2023 Target Bonus		2023 Earned Bonus			Supplemental Bonus(4)	Total Bonus Payout
	%(1)	$	%(2)	%(3)	$
Richard J. Hawkins	55	$320,443	70	38.5	$224,311	$0	$224,311
John C. McKew	50	$267,750	70	35.0	$187,425	$100,000	$287,425
Lori Lawley	40	$156,400	70	28.0	$109,480	$0	$109,480

(1) Target bonus percentage represents a percentage of base salary.

(2) Bonus awarded at 70% in consideration of goal achievement.

(3) Represents bonus percentage actually awarded.

(4) Represents a supplemental bonus award at the discretion of the Board.

Long-Term Equity Compensation

Equity incentives represent the largest at-risk element of our executive compensation program. Our equity incentives are designed to align the interests of our executive officers with those of our stockholders by creating an incentive for our executive officers to maximize stockholder value and to remain employed with us despite a competitive labor market.

In 2023, target long-term incentive awards were delivered in the form of time-based stock options, performance-based stock options and RSUs. The Compensation Committee looked to the successful nature of meeting company objectives and granted stock options and RSUs are a means to help retain executives and drive the company into the future. The Compensation Committee believes this vehicle mix further reinforces our pay for performance philosophy, as value is only provided to executives if stockholder value is created and the executive remains with the company.

The awards had the following vesting and performance criteria:

Time-vested Options - These options vest and become exercisable in a series of 48 successive, substantially equal monthly installments.

Performance-based Options - These options vest and become exercisable in three substantially equal installments on the first of the month following an increase of closing stock price, as defined as the closing stock price on Nasdaq Stock Market by at least 50%, 100% and 150%, respectively, above the closing stock price on December 31, 2022, when measured over 30 consecutive calendar days, provided such increase occurs within two years of the date of grant, otherwise such options shall be cancelled.

2023 Equity Grants

On February 1, 2023, our Compensation Committee granted the following equity awards to our executives as follows:

28

Executive	Time-vesting Stock Options (#)	Performance-based Stock Options (#)	RSUs (#)
Richard J. Hawkins	17,700	17,700	4,500
John C. McKew	8,000	8,000	2,000
Lori Lawley	6,000	6,000	1,000

Anti-Hedging and Anti-Pledging Policies

We have adopted a Policy on Stock Trading by Employees, Officers and Directors. That policy expressly prohibits our employees and directors from: (i) engaging in hedging transactions or (ii) pledging our stock as collateral.

Federal Tax Considerations

Section 162(m) of the Internal Revenue Code generally disallows public companies a tax deduction for federal income tax purposes of remuneration in excess of $1 million paid to the chief executive officer and certain other highly compensated executive officers in any taxable year. While our Compensation Committee considers tax deductibility as one of the factors in determining executive compensation, the Compensation Committee believes that we should retain the flexibility to provide compensation to our named executive officers that is not fully tax deductible when it believes that such payments are appropriate to attract and retain executive talent or meet other business objectives. Our Compensation Committee intends to continue to compensate our named executive officers in a manner consistent with the best interests of our Company and our stockholders even if any portion of such compensation is non-deductible.

In addition to considering the tax consequences, the Compensation Committee considers the accounting consequences of its decisions, including the impact of expenses being recognized in connection with equity-based awards, in determining the size and form of different equity-based awards.

Accounting Considerations

We account for equity compensation paid to our employees in accordance with Accounting Standards Codification, or ASC, topic 718, which requires us to measure and recognize compensation expense in our financial statements for all share-based payments based upon an estimate of their fair value over the service period of the award. We record cash compensation as an expense at the time the obligation is incurred.

401(k) Plan

Our employees, including our executive officers, are eligible to participate in our 401(k) plan. Our 401(k) plan is intended to qualify as a tax qualified plan under Section 401 of the Code. Pursuant to the terms of our 401(k) plan, we provide a non-elective employer contribution of up to 5% of each participant’s eligible compensation, with a possibility of additional discretionary contributions.

Other Benefits and Perquisites

We pay at least a portion of the premiums for medical insurance, dental insurance, life insurance and accidental death and dismemberment insurance benefits to all full-time employees, including our executive officers. These benefits are available to all employees, subject to applicable laws.

Employment Agreements

We have entered into employment agreements with each of the named executive officers. The material terms of the agreements that were in effect during fiscal 2023 for the named executive officers are summarized below. Each of these agreements also contains severance and change of control provisions discussed under the heading “Potential Payments Upon Termination or Change in Control” beginning on page 32 of this proxy statement.

29

Employment Agreement with Richard J. Hawkins

Pursuant to the employment agreement between us and Mr. Hawkins dated March 27, 2020, Mr. Hawkins earns an annual base salary, which is subject to annual review and adjustment by our Board. For 2023, Mr. Hawkins earned an annual base salary of $582,624. Mr. Hawkins is also eligible to receive an annual performance bonus based on his achievement of certain milestones and performance objectives. In 2023, Mr. Hawkins’ target bonus was set at 55% of his annual base salary, which was the same level as 2022.

Potential Payments Upon Termination or Change in Control

Under our 2019 Plan, the vesting of stock options granted to our employees and officers may be accelerated in connection with specified corporate transactions and change in control transactions. Other than as set forth in the tables below, none of our other option grants provide for acceleration of vesting of any options in connection with such a transaction, except for certain options originally granted under our 2000 Equity Incentive Plan that may vest upon a change in control if the acquirer does not assume outstanding option grants. In addition, under our 2010 Non-Employee Directors’ Stock Award Plan, in the event of a change in control, 100% of the shares subject to each director’s options will vest.

Under the terms of employment agreements with certain of our named executive officers in effect as of December 31, 2020, if we terminate such named executive officer’s employment for “cause” or such named executive officer resigns without “good reason,” such named executive officer is entitled to the following: (i) any salary earned but unpaid prior to termination; (ii) any benefits accrued prior to termination; (iii) all accrued but unused vacation; and (iv) any business expenses that were incurred but not reimbursed as of the date of termination (collectively, the “Accrued Obligations”). Following such termination, vesting of such named executive officer’s then outstanding stock options shall cease on the date of such termination.

Under the terms of employment agreements with such named executive officers, if we terminate such named executive officer’s employment without cause or such named executive officer resigns with good reason (other than in connection with a change in control), and in each case such named executive officer signs a general release and written acknowledgment of his or

32

her continuing obligations under his or her confidentiality and inventions assignment agreement with us, such named executive officer is entitled to the following: (i) payment of the Accrued Obligations; (ii) depending on the named executive officer and as described in the tables below, the equivalent of 12 or months of such named executive officer’s base salary as in effect immediately prior to the termination date, payable on the same basis and at the same time as previously paid and subject to employment tax withholdings and deductions; (iii) for certain of the named executive officers and as described in the tables below, a bonus payout equal to the most recent annual bonus paid to the named executive officer or a portion thereof; (iv) depending on the named executive officer and as described in the tables below, payment of such named executive officer’s COBRA premiums for 12 or 6 months to be paid in order for such named executive officer to maintain medical insurance coverage that is substantially equivalent to that which such named executive officer received immediately prior to the termination payment of premiums for his or her group health insurance and (v) 12 months accelerated vesting of such named executive officer’s equity compensation awards (so such executive becomes vested in the portion of such awards that would have become vested if executive remained employed for 365 days after the termination date) and depending on the named executive officer and as described in the tables below, extension of the window to exercise such options for up to 12 months. In the event that such named executive officer breaches his or her confidentiality, non-compete or non-solicitation obligations under his or her confidentiality and inventions assignment agreement with us, the payments described above, except for the Accrued Obligations, shall cease, and we shall have no further obligations to such named executive officer with respect thereto. Our obligation to pay such named executive officer’s COBRA premiums ceases upon such named executive officer’s eligibility for comparable coverage provided by a new employer.

Under the terms of the employment agreements with the named executive officers in effect as of December 31, 2021, if we (or any surviving or acquiring corporation) terminate a named executive officer’s employment without cause or a named executive officer resigns with good reason within one month prior to or 13 months following the effective date of a change in control (either constituting a “Change of Control Termination”), and in each case such named executive officer signs a general release and written acknowledgment of his or her continuing obligations under his or her confidentiality and inventions assignment agreement with us, such named executive officer is entitled to the following: (i) payment of the Accrued Obligations; (ii) depending on the named executive officer and as described in the tables below, the equivalent of 24, 18 or 12 months of such named executive officer’s base salary as in effect immediately prior to the termination date, payable on the same basis and at the same time as previously paid and subject to employment tax withholdings and deductions; (iii) depending on the named executive officer and as described in the tables below, a bonus payout equal to two, one and one-half or one times the most recent annual cash bonus paid to the named executive officer; (iv) depending on the named executive officer as described in the tables below, payment of such named executive officer’s COBRA premiums for 24, 18 or 12 months to be paid in order for such named executive officer to maintain medical insurance coverage that is substantially equivalent to that which such named executive officer received immediately prior to the termination payment of premiums for his or her group health insurance; and (v) we will vest 100% of the shares subject to such named executive officer’s equity compensation awards and such vesting shall occur upon the occurrence of the change of control in the case of a Change of Control Termination occurring prior to the change in control or upon termination in the case of a Change of Control Termination occurring after the change of control. If a named executive officer breaches his or her confidentiality, non-compete or non-solicitation obligations under his or her confidentiality and inventions assignment agreement with us, the payments described above, except for the Accrued Obligations, shall cease, and we shall have no further obligations to such named executive officer with respect thereto. Our obligation to pay such named executive officer’s COBRA premiums ceases upon such named executive officer’s eligibility for comparable coverage provided by a new employer.

The following tables reflect the estimated potential payments that would be payable to each named executive officer, upon a termination or change in control of us under the terms of his or her employment agreement in effect as of December 31, 2022. The amounts shown below reflect only the additional payments or benefits that each named executive officer would have received upon the occurrence of the respective triggering events listed below, but they do not include the value of payments or benefits that would have been earned, or any amounts associated with equity awards that would have vested, absent the triggering event. For purposes of calculating the potential payments set forth in the tables below, we have assumed that (i) the date of termination was December 31, 2023 and (ii) the stock price was $3.18, which was the per share closing price of our common stock on the NASDAQ Global Market on December 31, 2023.

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS, AND DIRECTOR INDEPENDENCE

We have not been a party since January 1, 2023 to any transactions, in which the amount involved in the transaction exceeds $120,000 (which is less than 1% of the average of our total assets at the end of the last two completed fiscal years), and in which any of our directors, executive officers or to our knowledge, beneficial owners of more than 5% of our capital stock had or will have a direct or indirect material interest, other than compensation, termination and change in control arrangements, which are described in more detail in the section entitled "Executive Compensation" beginning on page 24 of this proxy statement.

Policies and Procedures for Related Person Transactions

Our Board has adopted written policies and procedures for the review of any transaction, arrangement or relationship in which we are a participant, the amount involved exceeds $120,000 and one of our executive officers, directors, director nominees or 5% stockholders (or their immediate family members), each of whom we refer to as a "related person," has a direct or indirect material interest.

If a related person proposes to enter into such a transaction, arrangement or relationship, which we refer to as a "related person transaction," the related person must report the proposed related person transaction to our Audit Committee. The policy calls for the proposed related person transaction to be reviewed and, if deemed appropriate, approved by our Audit Committee. Whenever practicable, the reporting, review and approval will occur prior to entry into the transaction. If advance review and approval is not practicable, our Audit Committee will review, and, in its discretion, may ratify the related person transaction. Any related person transactions that are ongoing in nature will be reviewed annually.

A related person transaction reviewed under the policy will be considered approved or ratified if it is authorized by our Audit Committee after full disclosure of the related person’s interest in the transaction. As appropriate for the circumstances, our Audit Committee will review and consider:

•the related person's interest in the related person transaction;

•the approximate dollar value of the amount involved in the related person transaction;

•the approximate dollar value of the amount of the related person's interest in the transaction without regard to the amount of any profit or loss;

•whether the transaction was undertaken in the ordinary course of our business;

•whether the terms of the transaction are no less favorable to us than terms that could have been reached with an unaffiliated third party;

•the purpose of, and the potential benefits to us of, the transaction; and

•any other information regarding the related person transaction or the related person in the context of the proposed transaction that would be material to investors in light of the circumstances of the particular transaction.

Our Audit Committee may approve or ratify the transaction only if the Audit Committee determines that, under all of the circumstances, the transaction is in, or is not inconsistent with, our best interests. Our Audit Committee may impose any conditions on the related person transaction that it deems appropriate.

In addition to the transactions that are excluded by the instructions to the SEC’s related person transaction disclosure rule, our Board has determined that the following transactions do not create a material direct or indirect interest on behalf of related persons and, therefore, are not related person transactions for purposes of this policy:

•interests arising solely from the related person’s position as an executive officer of another entity (whether or not the person is also a director of such entity), that is a participant in the transaction, where (a) the related person and all other related persons own in the aggregate less than a 10% equity interest in such entity, (b) the related person and his or her immediate family members are not involved in the negotiation of the terms of the transaction and do not receive any special benefits as a result of the transaction or (c) the amount involved in the transaction equals less than the greater of $200,000 or 5% of the annual consolidated gross revenues of our receiving payment under the transaction; and

•a transaction that is specifically contemplated by provisions of our certificate of incorporation or bylaws.

The policy provides that transactions involving compensation of executive officers shall be reviewed and approved by our Compensation Committee in the manner specified in its charter.

Limitation of Liability and Indemnification

Our Bylaws require us to indemnify our directors to the fullest extent not prohibited by law and permit us to indemnify our officers, employees and other agents as set forth under Delaware law. We will indemnify any such person in connection with a proceeding initiated by such person only if such indemnification is expressly required by law, the proceeding was authorized by our Board, the indemnification is provided by us, in our sole discretion, pursuant to the Delaware General Corporation Law or other applicable law or is otherwise expressly required by our Bylaws. Section 145 of the Delaware General Corporation Law permits indemnification of officers, directors and other agents under specified circumstances and subject to specified limitations. Delaware law also permits a corporation not to hold its directors personally liable for monetary damages for breach of their fiduciary duties as directors, except for liability for:

•breach of their duty of loyalty to the corporation or its stockholders;

•acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law;

•unlawful payments of dividends or unlawful stock repurchases or redemptions; and

•any transaction from which the director derived an improper personal benefit.

These limitations of liability do not affect the availability of equitable remedies such as injunctive relief or rescission.

Our Bylaws also permit us to secure insurance on behalf of any officer, director, employee or other agent for any liability arising out of his or her actions in this capacity. We have obtained directors’ and officers’ liability insurance to cover certain liabilities described above.

We have entered into indemnity agreements with each of our directors that require us to indemnify such persons against any and all expenses, including attorneys’ fees, witness fees, judgments, fines, settlements and other amounts incurred, including expenses of a derivative action, in connection with any action, suit or proceeding or alternative dispute resolution mechanism, inquiry hearing or investigation, whether threatened, pending or completed, to which any such person may be made a party by reason of the fact that such person is or was one of our directors, officers or employees, provided that such person’s conduct did not constitute a breach of his or her duty of loyalty to us or our stockholders, and was not an act or omission not in good faith or which involved intentional misconduct or a knowing violation of laws. The indemnity agreements also set forth procedures that will apply in the event of a claim for indemnification thereunder. We believe that these provisions and agreements are necessary to attract and retain qualified persons as our directors.

At present, other than the previously mentioned matters, there is no pending litigation or proceeding involving any or our directors or officers for which indemnification is required or permitted, and we are not aware of any threatened litigation or proceeding that may result in a claim for indemnification.

Insofar as indemnification for liabilities arising under the Securities Act may be permitted by directors, executive officers or persons controlling us, we have been informed that in the opinion of the SEC, such indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable.

The Company has not yet selected the date of the annual meeting of stockholders for next year but currently plans to hold the meeting in May 2025. If the date of the 2025 annual meeting is advanced or delayed more than 30 days before or after the anniversary of the date of this Annual Meeting, notice by the stockholder to be timely must be so received no earlier than the close of business on the 120th day prior to such 2025 annual meeting and not later than the close of business on the later of the 90th day prior to such 2025 annual meeting or the 10th day following the day on which public announcement of the date of such meeting is first made.

Any such submission must be accompanied by the written consent of the proposed nominee to be named as a nominee and to serve as a director if elected.

Householding of Proxy Materials

The SEC has adopted rules that permit companies and intermediaries (e.g., brokers) to satisfy the delivery requirements for Notice of Internet Availability of Proxy Materials or other Annual Meeting materials with respect to two or more stockholders sharing the same address by delivering a single Notice of Internet Availability of Proxy Materials or other Annual Meeting materials addressed to those stockholders. This process, which is commonly referred to as “householding,” potentially means extra convenience forstockholders and cost savings for companies.

This year, a number of brokers with account holders who are Lumos stockholders will be “householding” our proxy materials. A single Notice of Internet Availability of Proxy Materialswill be delivered to multiple stockholders sharing an address unless contrary instructions have been received from the affected stockholders. Once you have received notice from your broker that they will be “householding” communications to your address, “householding” will continue until you are notified otherwise or until you revoke your consent. If, at any time, you no longer wish to participate in “householding” and would prefer to receive a separate Notice of Internet Availability of Proxy Materials, please notify your broker or Lumos. Direct your written request to Corporate Secretary, Lumos Pharma, Inc., 4200 Marathon Boulevard #200, Austin, TX 78756 or contact our Corporate Secretary at (512) 215-2630. We undertake to promptly deliver, upon written or oral request, a separate copy of our Notice of Internet Availability of Proxy Materials to stockholders at a shared address to which a single copy of such documents was delivered. Stockholders who currently receive multiple copies of Notice of Internet Availability of Proxy Materialsat their addresses and would like to request “householding” of their communications should contact their brokers.
