Board of Directors

Our board of directors is divided into three classes, with members of each class holding office for staggered three-year terms. There are currently two Class I directors (Brian Windsor, Ph.D. and Alan A. Musso), whose terms expire at the 2024 annual meeting of stockholders; one Class II director (William C. Fairey), whose term expires at the 2025 annual meeting of stockholders; and three Class III directors (Manuel C. Alves Aivado, M.D., Ph.D., Reinhard J. Ambros, Ph.D. and Josef H. von Rickenbach), whose terms expire at the 2026 annual meeting of stockholders.

Set forth below are the names of and certain information for each board member. The information presented includes each director’s principal occupation and business experience for the past five years and the names of other public companies of which he has served as a director during the past five years.

Mr. Musso holds a B.S. in accounting from Saint Mary’s College of California, and a Master’s Degree from the Thunderbird School of Global Management. We believe Mr. Musso is qualified to serve on our board of directors due to his extensive management and financial experience in the life sciences industry.

Class II Director

William C. Fairey has served as a member of our board of directors since October 2023. Mr. Fairey served as executive vice president and chief commercial officer of MyoKardia, Inc., a clinical-stage biopharmaceutical company discovering and developing targeted therapies for the treatment of serious cardiovascular diseases, from January 2019 to November 2020 prior to its acquisition by Bristol Myers Squibb in October 2020.

Dr. Aivado is a German board-certified physician for internal medicine, hematology, and medical oncology. He received an M.D. and Ph.D. from the Medical School of the University of Dusseldorf in Germany. We believe that Dr. Aivado is qualified to serve on our board of directors due to his previous service as our President and Chief Executive Officer, previous role as our Chief Medical Officer, extensive knowledge of our company, and significant background in pharmaceutical research and development.

Reinhard J. Ambros, Ph.D., has served as a member of our board of directors since June 2013.

Corporate Governance Matters

Our board of directors believes that good corporate governance is important to ensure that our company is managed for the long-term benefit of stockholders. This section describes key corporate governance guidelines and practices that our board of directors has adopted. Complete copies of our corporate governance guidelines, committee charters and code of conduct are available on the “Investors & Media—Corporate Governance” section of our website, which is located at www.aileronrx.com. Alternatively, you can request a copy of any of these documents by writing us at Aileron Therapeutics, Inc., 12407 N. Mopac Expy. Suite 250 #390, Austin, Texas 78758, Attention: Brian Windsor, Ph.D., President and Chief Executive Officer.

Corporate Governance Guidelines

Our board of directors has adopted corporate governance guidelines to assist in the exercise of its duties and responsibilities and to serve the best interests of our company and our stockholders. These guidelines, which provide a framework for the conduct of our board of directors’ business, provide that:

Board Leadership Structure

Our corporate governance guidelines provide that the nominating and corporate governance committee shall periodically assess the board of directors’ leadership structure, including whether the offices of Chief Executive Officer and chair of the board of directors should be separate. Our guidelines provide the board of directors with flexibility to determine whether the two roles should be combined or separated based upon our needs and the board of directors’ assessment of its leadership from time to time. We currently separate the roles of Chief Executive Officer and chair of the board of directors. Separating the duties of the chair of the board from the duties of the Chief Executive Officer allows our Chief Executive Officer to focus on our day-to-day business, while allowing the chair of the board to lead the board of directors in its fundamental role of providing advice to and independent oversight of management. Specifically, the chair of our board of directors presides over meetings of the board of directors, facilitates communications between management and the board of directors and assists with other corporate governance matters.

Our board of directors has three standing committees that currently consist of, and are chaired by, independent directors. Our board of directors delegates substantial responsibilities to the committees, which then report their activities and actions back to the full board of directors. We believe that the independent committees of our board of directors and their chairpersons promote effective independent governance. We believe this structure represents an appropriate allocation of roles and responsibilities for our company at this time because it strikes an effective balance between management and independent leadership participation in our board of director proceedings.

Our board of directors oversees our risk management processes directly and through its committees. Our management is responsible for risk management on a day-to-day basis. The role of our board of directors and its committees is to oversee the risk management activities of management. Our board of directors fulfills this duty by discussing with management the policies and practices utilized by management in assessing and managing risks and providing input on those policies and practices. In general, our board of directors oversees risk management activities relating to business strategy, acquisitions, capital allocation, organizational structure and certain operational risks; our audit committee oversees risk management activities related to financial controls and legal and compliance risks; our compensation committee oversees risk management activities relating to our compensation policies and practices; and our nominating and corporate governance committee oversees risk management activities relating to the composition of our board of directors and management succession planning. Each committee reports to the full board of directors on a regular basis, including reports with respect to the committee’s risk oversight activities as appropriate. In addition, since risk issues often overlap, committees from time to time request that the full board of directors discuss particular risks.

Board Determination of Independence

Applicable Nasdaq rules require a majority of a listed company’s board of directors to be comprised of independent directors within one year of listing. In addition, the Nasdaq rules require that, subject to specified exceptions, each member of a listed company’s audit, compensation and nominating and corporate governance committees be independent. Audit committee members must also satisfy the independence criteria set forth in Rule 10A-3 under the Securities Exchange Act of 1934, as amended, or the Exchange Act, and compensation committee members must also satisfy the independence criteria set forth in Rule 10C-1 under the Exchange Act. Under applicable Nasdaq rules, a director will only qualify as an “independent director” if, in the opinion of the listed company’s board of directors, that person does not have a relationship that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director. In order to be considered independent for purposes of Rule 10A-3, a member of an audit committee of a listed company may not, other than in his or her capacity as a member of the audit committee, the board of directors, or any other board committee, accept, directly or indirectly, any consulting, advisory, or other compensatory fee from the listed company or any of its subsidiaries or otherwise be an affiliated person of the listed company or any of its subsidiaries. In order to be considered independent for purposes of Rule 10C-1, the board must consider, for each member of a compensation committee of a listed company, all factors specifically relevant to determining whether a director has a relationship to such company which is material to that director’s ability to be independent from management in connection with the duties of a compensation committee member, including, but not limited to: the source of compensation of the director, including any consulting, advisory or other compensatory fee paid by such company to the director; and whether the director is affiliated with the company or any of its subsidiaries or affiliates.

In January 2024, in connection with the 2023 annual meeting of stockholders, our board of directors undertook a review of the composition of our board of directors and its committees and the independence of each director. Based upon information requested from and provided by each director concerning his or her background, employment and affiliations, including family relationships, our board of directors determined that, as of the 2023 annual meeting of stockholders, each of our directors, with the exception of Manuel C. Alves Aivado, M.D., Ph.D., was an “independent director” as defined under applicable Nasdaq rules, including, in the case of all the members of our audit committee, the independence criteria set forth in Rule 10A-3 under the Exchange Act, and in the case of all the members of our compensation committee, the independence criteria set forth in Rule 10C-1 under the Exchange Act. In making such determination, our board of directors considered the relationships that each such non-employee director has with our company and all other facts and circumstances that our board of directors deemed relevant in determining his or her independence, including the beneficial ownership of our capital stock by each non-employee director. Dr. Aivado was not an independent director under these rules because he was our President and Chief Executive Officer as of the 2023 annual meeting of stockholders. Our board of directors will undertake a review of the composition of our board of directors and its committees and the independence of each director in connection with the 2024 annual meeting of stockholders.

Board of Director Meetings and Attendance

Our board of directors held 13 meetings during the year ended December 31, 2023, or fiscal 2023. During fiscal 2023, each of the directors then in office attended at least 75% of the aggregate of the number of board of director meetings held during the period which the person has been a director and the number of meetings held by all committees of the board of directors on which such director then served (during the periods that such person served). Our corporate governance guidelines provide that directors are expected to attend the annual meeting of stockholders. Dr. Aivado and Mr. von Rickenbach attended the 2023 annual meeting of stockholders.

Communicating with our Directors

Our board of directors provides a process for stockholders to send communications to the board. Any interested party with concerns about our company may report such concerns to the board of directors, or the chair of our board of directors, or otherwise the chair of the nominating and corporate governance committee, by submitting a written communication to the attention of such director at the following address:

c/o Aileron Therapeutics, Inc.

12407 N. Mopac Expy. Suite 250, #390

Austin, Texas 78758

You may submit your concern anonymously or confidentially by postal mail. You may also indicate whether you are a stockholder, customer, supplier, or other interested party.

A copy of any such written communication may also be forwarded to our legal counsel, and a copy of such communication may be retained for a reasonable period of time. The director may discuss the matter with our legal counsel, with independent advisors, with non-management directors, or with our management, or may take other action or no action as the director determines in good faith, using reasonable judgment and discretion.

Communications may be forwarded to all directors if they relate to important substantive matters and include suggestions or comments that may be important for the directors to know. In general, communications relating to corporate governance and long-term corporate strategy are more likely to be forwarded than communications relating to ordinary business affairs, personal grievances, and matters as to which we tend to receive repetitive or duplicative communications.

The audit committee oversees the procedures for the receipt, retention, and treatment of complaints received by us regarding accounting, internal accounting controls, or audit matters, and the confidential, anonymous submission by employees of concerns regarding questionable accounting, internal accounting controls, or auditing matters. We have also established a toll-free telephone number for the reporting of such activity, which is 866-869-5217.

Committees of the Board of Directors

We have established an audit committee in accordance with Section 3(a)(58)(A) of the Exchange Act, a compensation committee, and a nominating and corporate governance committee. Each of these committees operates under a charter that has been approved by our board of directors. A copy of each committee’s charter can be found under the “Investors & Media—Corporate Governance” section of our website, located at www.aileronrx.com.

Audit Committee

The current members of our audit committee are Reinhard J. Ambros, Ph.D., Alan A. Musso, and Josef H. von Rickenbach. Mr. Musso has served as chair of our audit committee since October 31, 2023.

connection with the Lung Acquisition. William T. McKee served as a member and chair of our audit committee and Jodie P. Morrison served as member of our audit committee until their resignations from our board of directors on October 31, 2023 in connection with the Lung Acquisition. In fiscal 2023, our audit committee met eight times. Our audit committee’s responsibilities include:

All audit and non-audit services, other than de minimis non-audit services, to be provided to us by our independent registered public accounting firm must be approved in advance by our audit committee.

Our board of directors has determined that Mr. Musso is an “audit committee financial expert” as defined in applicable SEC rules and that each of the members of our audit committee possesses the financial sophistication required for audit committee members under Nasdaq rules. We believe that the composition of our audit committee meets the requirements for independence under current Nasdaq and SEC rules and regulations.

Compensation Committee

The current members of our compensation committee are Dr. Ambros, William C. Fairey, and Mr. Musso. Dr. Ambros has served as the chair of the compensation committee since October 31, 2023.

7

Our compensation committee may delegate to one or more executive officers the power to grant options or other stock awards pursuant to our incentive plans to employees of the company who are not executive officers or Senior Vice Presidents.

We believe that the composition of our compensation committee meets the requirements for independence under current Nasdaq and SEC rules and regulations.

Nominating and Corporate Governance Committee

The current members of our nominating and corporate governance committee are Mr. Fairey and Mr. von Rickenbach. Mr. Fairey has served as the chair of the nominating and corporate governance committee since October 31, 2023.

In fiscal 2023, our nominating and corporate governance committee did not meet. Our nominating and corporate governance committee’s responsibilities include:

We believe that the composition of our nominating and corporate governance committee meets the requirements for independence under current Nasdaq and SEC rules and regulations.

Director Nomination Process

The process followed by our nominating and corporate governance committee to identify and evaluate director candidates includes requests to board members and others for recommendations, meetings from time to time to evaluate biographical information and background material relating to potential candidates and interviews of selected candidates by members of the nominating and corporate governance committee and our board of directors.

Criteria and Diversity

In considering whether to recommend to our board of directors any particular candidate for inclusion in our board of directors’ slate of recommended director nominees, including candidates recommended by stockholders, the nominating and corporate governance committee of our board of directors applies the criteria set forth in our corporate governance guidelines. These criteria include the candidate’s integrity, business acumen, knowledge of our business and industry, the ability to act in the interests of all stockholders and lack of conflicts of interest.

8

Our nominating and corporate governance committee does not have a policy (formal or informal) with respect to diversity, but believes that our board, taken as a whole, should embody a diverse set of skills, experiences and backgrounds. In this regard, the nominating and corporate governance committee also takes into consideration the diversity (for example, with respect to gender, race and national origin) of our board members. The nominating and corporate governance committee does not make any particular weighting of diversity or any other characteristic in evaluating nominees and directors.

Stockholder Nominations

Stockholders may recommend individuals to our nominating and corporate governance committee for consideration as potential director candidates by submitting their names, together with appropriate biographical information and background materials and a statement as to whether the stockholder or group of stockholders making the recommendation has beneficially owned more than 5% of our common stock for at least a year as of the date such recommendation is made, to Aileron Therapeutics, Inc., Attention: Nominating and Corporate Governance Committee, 12407 N. Mopac Expy. Suite 250 #390, Austin, Texas 78758. Assuming that appropriate biographical and background material has been provided in accordance with the procedures set forth in our definitive proxy statement for our 2023 annual meeting of stockholders filed with the SEC on January 29, 2024 (the “2023 Proxy Statement”) under the heading “Other Matters – Stockholder Proposals for our 2024 Annual Meeting”, the committee will evaluate stockholder-recommended candidates by following substantially the same process, and applying substantially the same criteria, as it follows for candidates submitted by others. If the board of directors determines to nominate a stockholder-recommended candidate and recommends his or her election, then his or her name will be included in our proxy card for the next annual meeting.

Stockholders also have the right under our by-laws to directly nominate director candidates, without any action or recommendation on the part of the nominating and corporate governance committee or our board of directors, by following the procedures set forth in our 2023 Proxy Statement under “Other Matters – Stockholder Proposals for our 2024 Annual Meeting.”

Board Diversity Matrix

In accordance with Nasdaq’s recently adopted board diversity listing standards, we are also disclosing aggregated statistical information about the members of our board directors as voluntarily identified to us by each of our directors.

Anti-Hedging Policy

Our insider trading policy expressly prohibits all of our employees, including our named executive officers, as well as our directors, from engaging in speculative transactions in our stock, including short sales, puts/calls, hedging transactions and margin accounts or pledges.

Clawback Policy

In November 2023, we adopted a “clawback policy” compliant with Nasdaq listing standards which provides that, in the event that we are required to prepare an accounting restatement for periods ending on or after October 2, 2023, we will attempt to recover from our current or former executive officers the pre-tax amount of incentive-based compensation in excess of what would have been paid to such executive officer after giving effect to the accounting restatement during the three completed fiscal years immediately preceding the earlier of (i) the date the board of directors, or a committee of the board of directors, or the officer or officers of the company authorized to take such action if board action is not required, concludes, or reasonably should have concluded, that the company is required to prepare an accounting restatement, or (ii) the date a court, regulator, or other legally authorized body directs the company to prepare an accounting restatement. For purposes of the policy, incentive-based compensation means any compensation that is granted, earned or vested based wholly or in part upon the attainment of any measures determined and presented in accordance with the accounting principles used in preparing the Company’s financial statements, and any measures that are derived wholly or in part from such measures (whether or not such measures are presented within the company’s financial statements or included in a filing made with the SEC); stock price; and total stockholder return. If the incentive-based compensation is based on our stock price or total stockholder return and the amount of excess incentive-based compensation is not calculable directly from the information in an accounting restatement, the amount recovered shall be based on a reasonable estimate of the effect of the accounting restatement on the stock price or total stockholder return upon which the incentive-based compensation was received.

Code of Business Conduct and Ethics

We have adopted a written code of business conduct and ethics that applies to our directors, officers and employees, including our principal executive officer and principal financial officer. A copy of the code is available on the “Investors & Media—Corporate Governance” section of our website, which is located at www.aileronrx.com. Our board of directors is responsible for overseeing the code of business conduct and ethics and must approve any waivers of the code for directors, officers and employees. If we make any substantive amendments to, or grant any waivers from, the code of business conduct and ethics for any officer or director, we will disclose the nature of such amendment or waiver on our website or in a current report on Form 8-K.

Item 11. Executive Compensation.

This section discusses the material elements of our executive compensation policies for our “named executive officers” and the most important factors relevant to an analysis of these policies. For 2023, our “named executive officers” are Dr. Aivado, our former Chief Executive Officer; Dr. Windsor, our President and Chief Executive Officer who was serving as an executive officer as of December 31, 2023 and was our other most highly compensated executive officer serving at year end (other than our Chief Executive Officer); and one individual who was no longer serving as an executive officer as of December 31, 2023, D. Allen Annis, Ph.D., our former Senior Vice President, Research. In addition, this section provides qualitative information regarding the manner and context in which compensation is awarded to and earned by our named executive officers and is intended to place in perspective the data presented in the following tables and the corresponding narrative.

Summary Compensation Table

The following table sets forth information regarding compensation awarded to, earned by or paid to our named executive officers during the years indicated.

Narrative Disclosure to Summary Compensation Table

We review compensation for our executive officers annually. The material terms of the elements of our executive compensation program for 2023 are described below.

Our compensation committee sets base salaries and bonus targets, and grants bonuses and equity incentive awards to our executive officers. In setting base salaries and bonus targets and granting equity incentive awards, our compensation committee considers compensation for comparable positions in the market, the historical compensation levels of our executives, individual and corporate performance as compared to our expectations and objectives, our desire to motivate our employees to achieve short- and long-term results that are in the best interests of our stockholders, and a long-term commitment to our company. In granting bonuses, our compensation committee considers corporate and individual performance.

As part of our annual compensation process, our President and Chief Executive Officer prepares performance evaluations for the other executive officers and recommends annual salary increases, annual stock option awards

11

and cash bonuses to the compensation committee. The compensation committee conducts a performance evaluation of our President and Chief Executive Officer. The compensation committee consults with the board of directors as to the achievement of corporate objectives that drive compensation awards.

In February 2022 and December 2022, the compensation committee engaged Radford as its independent compensation consultant to provide comparative data on executive and director compensation practices in our industry and assess our executives’ and directors’ compensation relative to comparable companies for 2022 and 2023 respectively.

Base Salary

We use base salaries to recognize the experience, skills, knowledge and responsibilities required of all our employees, including our named executive officers. None of our named executive officers is currently party to an employment agreement or other agreement or arrangement that provides for automatic or scheduled increases in base salary.

In March 2022, based upon comparative data on executive compensation provided by Radford and annual performance reviews conducted by our compensation committee of our named executive officers, our compensation committee increased (i) Dr. Aivado’s annual base salary to $587,336, and (ii) Dr. Annis’ annual base salary to $404,100.

Our compensation committee determined not to make any adjustments to our named executive officers’ base salaries in 2023. Our compensation committee has not yet determined whether to make any adjustments to our named executive officers’ base salaries for 2024.

Cash Incentives

The compensation committee awards annual performance-based cash bonuses to our executive officers for up to a specific percentage of his salary as a vehicle to reward achievement of value-driving milestones and recognize individual performance.

Pursuant to the terms of Dr. Aivado’s September 2018 employment agreement, Dr. Aivado was eligible to receive, commencing in 2019 and for each calendar year thereafter that Dr. Aivado is employed by us, a discretionary performance target bonus of up to 50% of his annual base salary based on the achievement of performance milestones set by either our board of directors or the compensation committee of the board.

Pursuant to the terms of Dr. Windsor’s employment agreement, Dr. Windsor is eligible to receive an annual bonus based on a bonus target of 45% of his annual base salary based on performance against goals and at the discretion of our board of directors.

The compensation committee determined not to award cash bonuses to our executive officers for their performance in 2022. In addition, the compensation committee determined not to change the target performance-based cash bonuses for our executive officers for 2023, which remained at 50% for Dr. Aivado and 45% for Dr. Windsor.

On February 9, 2024, the compensation committee determined to award a cash bonus of $204,375 to Dr. Windsor for his performance in 2023. The compensation committee determined not to award cash bonuses to our other executive officers for their performance in 2023.

Equity Incentives

Although we do not have a formal policy with respect to the grant of equity incentive awards to our executive officers, or any formal equity ownership guidelines applicable to them, we believe that equity grants provide our

12

executives with a strong link to our long-term performance, create an ownership culture and help to align the interests of our executives and our stockholders. In addition, we believe that equity grants with a time-based vesting feature promote executive retention because this feature incents our executive officers to remain in our employment during the vesting period, and equity grants with a performance-based feature incents our executive officers to focus on what we see as key business goals. Accordingly, the compensation committee periodically reviews the equity incentive compensation of our named executive officers and from time to time may grant equity incentive awards to them in the form of stock options.

Our compensation committee determined not to grant equity awards to our executive officers in for their performance in 2022 or 2023.

All Other Compensation

We determined to cease providing our executive officers with commuting reimbursements, beginning May 1, 2023.

Outstanding Equity Awards at Fiscal Year End 2023

The following table sets forth information regarding outstanding equity awards held by our named executive officers as of December 31, 2023:

Director Compensation

Our non-employee directors receive compensation under our director compensation program. We intend to review our director compensation program in 2024.

Cash Retainer

Under this program, we pay our non-employee directors a cash retainer for service on the board of directors and for service on each committee on which the director is a member. The chair of each committee and the chair of the board of directors receive higher retainers for such service. These fees are payable in arrears in four equal quarterly installments on the last day of each quarter, subject to proration for any portion of such quarter that the director is not serving on our board of directors, on such committee or in such position. The fees paid to non-employee directors for service on the board of directors and for service on each committee of the board of directors on which the director is a member are as follows:

Equity Grants

In March 2022, based upon comparative data on board compensation provided by Radford, the board of directors revised the director compensation program to increase the annual stock option grants, such that each non-employee director who has served on our board of directors for at least six months will receive an option to purchase will receive an option to purchase 2,725 shares of our common stock immediately following each annual meeting of our stockholders. In addition, the compensation committee revised the director compensation program to increase the initial grant, such that each new member of the board will receive an option to purchase 5,450 shares of our common stock upon election to the board. All other provisions of the director compensation program, including the vesting terms for such grants, remain unchanged.

We also reimburse our non-employee directors for reasonable travel and out-of-pocket expenses incurred in connection with attending our board of directors and committee meetings.

We do not pay any compensation to Dr. Windsor, our President and Chief Executive Officer, in connection with his service on our board of directors. The compensation that we pay to Dr. Windsor and Dr. Aivado, our former Chief Executive Officer is discussed earlier in this “Executive Compensation” section.

The following table sets forth information regarding compensation earned by our non-employee directors for service during fiscal 2023. Jeffrey A. Bailey, William T. McKee and Jodie P. Morrison resigned from the board as of October 31, 2023. Mr. Fairey and Mr. Musso joined the board as of October 31, 2023 in connection with the Lung Acquisition.

As of December 31, 2023, our non-employee directors that served in such capacity during fiscal 2023 held the following stock options, including stock options assumed by us in the Lung Acquisition, all of which were granted under (a) our 2017 Stock Incentive Plan, or 2017 Plan, (b) our 2021 Plan and (c) Lung’s 2013 Plan:

Item 12. Security Ownership of Certain Beneficial Owners and Management and Related Stockholder Matters.

Unless otherwise provided below, the following table sets forth information regarding beneficial ownership of our common stock as of April 25, 2024, by:

Beneficial ownership is determined in accordance with the rules and regulations of the SEC and includes voting or investment power with respect to our common stock. Percentage of beneficial ownership is based on 16,868,480 shares of our common stock outstanding as of April 25, 2024. In addition, shares of common stock

15

subject to options, warrants, or other rights currently exercisable or exercisable within 60 days of April 25, 2024, are deemed outstanding and beneficially owned for the purpose of computing the percentage beneficially owned by (i) the person or entity holding such options, warrants or other rights (but not any other person or entity) and (ii) the directors and executive officers as a group. Except as otherwise noted, the persons and entities in this table have sole voting and investing power with respect to all of the shares of our common stock beneficially owned by them, subject to community property laws, where applicable. Except as otherwise set forth below, the address of the beneficial owner is c/o Aileron Therapeutics, Inc., 12407 N. Mopac Expy. Suite 250 #390, Austin, Texas 78758.

Securities Authorized for Issuance Under Equity Compensation Plans

The following table contains information about our equity compensation plans as of December 31, 2023. As of December 31, 2023, we had five equity compensation plans, each of which was approved by our stockholders: our 2006 Equity Incentive Plan, as amended, or the 2006 Plan, our 2016 Stock Incentive Plan, or the 2016 Plan, our 2017 Plan, our 2021 Plan, and our 2017 Employee Stock Purchase Plan, or 2017 ESPP.

Item 13. Certain Relationships and Related Transactions, and Director Independence.

Transactions with Related Persons

Since January 1, 2022, we have engaged in the following transactions in which the amount involved exceeded the lesser of $120,000 or one percent of our total assets at year end for fiscal years 2023 and 2022, and any of our executive officers, directors, or beneficial holders of more than 5% of any class of voting securities, or any of their affiliates, had a direct or indirect material interest. We believe that all of these transactions were on terms comparable to terms that could have been obtained from unrelated third parties.

Lung Acquisition and Financing

Upon the closing of the Lung Acquisition, entities associated with Bios Partners became beneficial owners of more than 5% of our voting securities. Immediately following the closing of the Lung Acquisition, we entered into a Stock and Warrant Purchase Agreement, or the Purchase Agreement, with a group of accredited investors, or the Investors, led by Bio Partners, the majority stockholder of Lung prior to the closing of the Lung Acquisition, and including Nantahala Capital, as well as additional undisclosed investors, pursuant to which we issued and sold (i) an aggregate of 4,707 shares of Series X Preferred Stock, and (ii) warrants, or the Warrants, to purchase up to an aggregate of 2,353,500 shares of common stock, or the Warrant Shares, for an aggregate purchase price of approximately $18.4 million, which included the conversion of certain convertible promissory notes in the aggregate principal amount of approximately $1.6 million issued by Lung to Bios Partners prior to the closing of the Lung Acquisition at a 10% discount to the per share price of the Series X Preferred Stock, or the Financing.

Upon the closing of the Financing, (i) Bios Clinical Opportunity Fund, LP purchased 1,136 shares of Series X Preferred Stock and a warrant to purchase 568,000 shares of common stock for a purchase price of approximately $4.4 million, (ii) Bios Fund III NT, LP purchased 125 shares of Series X Preferred Stock and a warrant to purchase 62,500 shares of common stock for a purchase price of approximately $0.5 million, (iii) Bios Fund III QP, LP purchased 777 shares of Series X Preferred Stock and a warrant to purchase 388,500 shares of common stock for a purchase price of approximately $3.0 million, and (iv) Bios Fund III, LP purchased 119 shares of Series X Preferred Stock and a warrant to purchase 59,500 shares of common stock for a purchase price of approximately $0.5 million. In addition, certain convertible promissory notes issued by Lung to Bios Clinical Opportunity Fund, LP in an amount of approximately $1.6 million were converted, at a 10% discount to the per share price of the Series X Preferred Stock, into 444 shares of Series X Preferred Stock and a warrant to purchase 222,000 shares of common stock.

18

Lock-up Agreements

Concurrently and in connection with the Lung Acquisition, we entered into lock-up agreements with entities associated with Bios Partners, pursuant to which each entity is subject to a 180-day lockup on the sale or transfer of shares of common stock or any securities convertible into or exercisable or exchangeable for shares of common stock (including without limitation, shares of common stock or such other securities which may be deemed to be beneficially owned by such entity in accordance with the rules and regulations of the SEC and our securities which may be issued upon exercise of an option to purchase shares of common stock or a warrant to purchase shares of common stock) that were held by such entity at the closing of the Lung Acquisition and hereafter owned by such entity, including those shares issued in the Lung Acquisition, subject to certain customary exceptions.

Registration Rights Agreement

In connection with the Financing, we entered into a Registration Rights Agreement with the a group of accredited investors, or the Investors, led by Bio Partners, the majority stockholder of Lung prior to the closing of the Lung Acquisition, and including Nantahala Capital, as well as additional undisclosed investors. Pursuant to the Registration Rights Agreement, we agreed to prepare and file a resale registration statement with the SEC by the within 90 calendar days following the closing of the Financing and such registration statement was declared effective on February 5, 2024. The Registration Rights Agreement also contains customary terms, including an obligation to indemnify the Investors, their officers, directors, agents, partners, members, managers, stockholders, affiliates and employees under the registration statement from certain liabilities and pay all fees and expenses (excluding any underwriting discounts and selling commissions and all legal fees and expenses of legal counsel for the Investors, except for reasonable and documented fees and expenses in an amount not to exceed $30,000 of the Investors that hold a majority in interest of the registrable securities in connection with the review of the registration statement) incident to our obligations under the Registration Rights Agreement.

Indemnification Agreements

Our restated certificate of incorporation, as amended, provides that we will indemnify our directors and officers to the fullest extent permitted by Delaware law. In addition, we have entered into indemnification agreements with each of our officers and directors that may be broader in scope than the specific indemnification provisions contained in the Delaware General Corporation Law. See “Executive Compensation—Limitations on Liability and Indemnification” for additional information regarding these agreements.

Policies and Procedures for Related Person Transactions

Our board of directors has adopted a written related person transaction policy to set forth 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, 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 Chief Executive Officer. The policy calls for the proposed related person transaction to be reviewed and 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, the committee will review and, in its discretion, may ratify the related person transaction. The policy also permits the chair of the audit committee to review and, if deemed appropriate, approve proposed related person transactions that arise between committee meetings, subject to ratification by the committee at its next meeting. Any related person transactions that are ongoing in nature will be reviewed annually.

19

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

The audit committee may approve or ratify the transaction only if the committee determines that, under all of the circumstances, the transaction is in our best interests. The 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 of directors 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:

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

Employment Agreements

Brian Windsor, Ph.D.

In February 2014, Lung entered into an employment agreement with Brian Windsor, Ph.D., as amended by a letter agreement between Dr. Windsor and Lung in February 2023 and as amended by a letter agreement between Dr. Windsor and Lung in October 2023. Pursuant to the employment agreement, as amended, Dr. Windsor is entitled to an annual base salary of $500,000 and is eligible to receive an annual bonus based on a bonus target of 45% of his annual base salary based on performance against goals and at the discretion of the board of directors. In addition, pursuant to the employment agreement, in the event that Dr. Windsor is terminated without cause or resigns for good reason then, subject to the execution of a release agreement, Dr. Windsor will be eligible to receive twelve (12) months’ base salary in the form of severance payments, less statutory deductions and withholdings, payable in the form of salary continuation.

20

Manuel C. Alves Aivado, M.D., Ph.D.

In September 2018, in connection with our appointment of Dr. Aivado as our President and Chief Executive Officer, we entered into a new employment agreement with Dr. Aivado, which superseded his July 2014 employment agreement with us. Pursuant to the terms of Dr. Aivado’s September 2018 employment agreement, we agreed to pay Dr. Aivado a base salary at a rate of $41,666.67 per month, which was based on an annualized base salary of $500,000. Beginning in 2019, following the end of each calendar year that Dr. Aivado is employed by us, Dr. Aivado will be eligible to receive a discretionary performance target bonus of up to 50% of his then annual base salary based on the achievement of performance milestones set by either our board of directors or the compensation committee of the board. The employment agreement also provided that following the end of the 2018 calendar year, Dr. Aivado was eligible to receive a discretionary performance target bonus calculated on the basis of 35% of his base salary as of August 31, 2018 pro-rated for the first eight months of the fiscal year, and 50% of his current base salary under the employment agreement pro-rated for the remaining four months of the fiscal year. The amount of such bonus and the achievement of such milestones were determined by our board in its sole discretion. Dr. Aivado is also entitled to receive reimbursement of up to $4,400 per month for travel and living accommodations pursuant to the employment agreement.

On March 11, 2024, Dr. Aivado agreed that his employment with us would cease and he would resign from his position as Chief Executive Officer of the Company, effective as of March 11, 2024 (the “Separation Date”).

In connection with Dr. Aivado’s separation from the Company, and in accordance with the Severance Agreement, dated as of September 6, 2018, between the Company and Dr. Aivado (the “Severance Agreement”), Dr. Aivado is entitled to receive his base salary for eighteen (18) months following the Separation Date, payments on Dr. Aivado’s behalf of the monthly premiums for medical insurance coverage under COBRA until the earlier of the date that is eighteen (18) months following the Separation Date or the date on which Dr. Aivado becomes eligible to receive group health insurance coverage through another employer, a lump sum payment equal to one and one-half times Dr. Aivado’s target bonus for the 2024 calendar year, and acceleration in full of the vesting of any unvested equity awards. Dr. Aivado’s receipt of these post-separation benefits under the Severance Agreement is conditioned upon his execution of a severance and release of claims agreement with the Company.

D. Allen Annis, Ph.D.

In November 2007, we entered into an employment offer letter with D. Allen Annis, Ph.D. The offer letter established Dr. Annis’ title, his base salary, his eligibility for an annual bonus, and his eligibility for benefits made available to employees generally. The offer letter established that Dr. Annis’ employment was at will. Pursuant to the offer letter, we granted Dr. Annis options to purchase 3,750 shares of our common stock under our 2006 Plan, at a price per share equal to the fair market value of one share of our common stock on the date of the option grant as determined by our board.

On April 24, 2023, we entered into a separation and release of claims agreement with Dr. Annis, which provided for Dr. Annis’ separation of employment as our Senior Vice President, Research, effective as of April 15, 2023. In accordance with the terms of the separation agreement, we agreed to provide Dr. Annis with (i) a lump sum payment representing an aggregate amount equal to nine months of Dr. Annis’ salary as of April 15, 2023, subject to applicable taxes and withholdings, and (ii) payment on Dr. Annis’ behalf of the monthly premiums for group medical insurance coverage under COBRA until the earlier of the date that is nine months after April 15, 2023 and the date on which Dr. Annis becomes eligible to receive the same or substantially similar group health insurance coverage through another employer. The separation agreement also contains a release of claims by Dr. Annis, subject to customary exceptions, and covenants not to solicit or disparage and to cooperate with us.

In April 2023, we also entered into a consulting agreement with Dr. Annis for an initial term of six months. We will pay Dr. Annis an hourly consulting fee equal to $500 per hour for his services under the consulting

21

agreement, which may not exceed 10 hours per month without our prior written consent. The consulting agreement also provides that Dr. Annis may be eligible to receive a cash bonus award in recognition of his services under the consulting agreement, in an amount not to exceed $50,000, as determined in the sole discretion of our compensation committee. Pursuant to the terms of the consulting agreement, Dr. Annis’ options to purchase shares of our common stock continue to vest and be exercisable during the term of the consulting agreement. The consulting agreement may be terminated by Dr. Annis or us for any reason upon fifteen days’ advance written notice to the other party.

Other Agreements

We have also entered into employee confidentiality, inventions, non-solicitation and non-competition agreements with each of our named executive officers. Under the employee confidentiality, inventions, non-solicitation and non-competition agreements, each named executive officer has agreed (1) not to compete with us during his employment and for a period of one year after the termination of his employment, (2) not to solicit our employees during his employment and for a period of two years after the termination of his employment, (3) to protect our confidential and proprietary information and (4) to assign to us related intellectual property developed during the course of his employment.

401(k) Retirement Plan

We maintain a 401(k) retirement plan that is intended to be a tax-qualified defined contribution plan under Section 401(k) of the Internal Revenue Code. In general, all of our employees are eligible to participate, beginning on the first day of the month following commencement of their employment. The 401(k) plan includes a salary deferral arrangement pursuant to which participants may elect to reduce their current compensation by up to the statutorily prescribed limit, equal to $20,500 in 2022 and $22,500 in 2023, and have the amount of the reduction contributed to the 401(k) plan. Participants over the age of 50 are entitled to an additional catch-up contribution up to the statutorily prescribed limit, equal to $6,500 and 2022 and $7,500 in 2023. In March 2021, our compensation committee adopted a 100% match on the first 4% of eligible compensation, which remained applicable in 2022 and 2023. This was a non-voluntary contribution by the Company for 2022 and 2023.

Limitations on Liability and Indemnification

As permitted by Delaware law, we adopted provisions in our restated certificate of incorporation, as amended, that limit or eliminate the personal liability of our directors. Our restated certificate of incorporation, as amended, limits the personal liability of directors for breach of fiduciary duty to the maximum extent permitted by the General Corporation Law of the State of Delaware and provides that no director will have personal liability to us or to our stockholders for monetary damages for breach of fiduciary duty. However, these provisions do not eliminate or limit the liability of any of our directors:

Any amendment to or repeal of these provisions will not eliminate or reduce the effect of these provisions in respect of any act, omission or claim that occurred or arose prior to such amendment or repeal. If the General Corporation Law of the State of Delaware is amended to provide for further limitations on the personal liability of directors of corporations, then the personal liability of our directors will be further limited to the greatest extent permitted by the General Corporation Law of the State of Delaware.

In addition, our restated certificate of incorporation, as amended, provides that we must indemnify our directors and officers and we must advance expenses, including attorneys’ fees, to our directors and officers in connection with legal proceedings, subject to very limited exceptions.

22

We maintain a general liability insurance policy that covers specified liabilities of our directors and officers arising out of claims based on acts or omissions in their capacities as directors or officers. In addition, we entered into indemnification agreements with each of our officers and directors. These indemnification agreements require us, among other things, to indemnify each such director or officer for some expenses, including attorneys’ fees, judgments, fines and settlement amounts, incurred by him or her in any action or proceeding arising out of his or her service as one of our directors or officers.

Some of our non-employee directors may, through their relationships with their employers, be insured or indemnified against specified liabilities incurred in their capacities as members of our board of directors.

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

Item 14. Principal Accounting Fees and Services.

Audit Fees and Services

Our audit committee appointed the firm of Marcum LLP, or Marcum, an independent registered public accounting firm, as independent auditors for the fiscal year ended December 31, 2023 on January 10, 2024, and we formally engaged Marcum on January 9, 2024. Prior to the appointment of Marcum, PricewaterhouseCoopers LLP, or PricewaterhouseCoopers, served as our independent registered public accounting firm. On October 30, 2023, the audit committee dismissed PricewaterhouseCoopers from service as our independent registered public accounting firm, effective as of the closing of the Lung Acquisition.

PricewaterhouseCoopers was our independent registered public accounting firm for the year ended December 31, 2022 and the subsequent interim period from January 1, 2023 to October 31, 2023. The following table summarizes the fees of PricewaterhouseCoopers for the year ended December 31, 2022 as well as the subsequent interim period from January 1, 2023 to October 31, 2023. All such services and fees were pre-approved by our audit committee in accordance with the “Pre-Approval Policies and Procedures” described below. During the years ended December 31, 2023 and December 31, 2022, no services were provided to us by Marcum.

“Audit Fees” consist of fees for the audit of our annual financial statements, the review of the interim financial statements included in our quarterly reports on Form 10-Q and other professional services provided in connection with regulatory filings or engagements.

(2) “All Other Fees” consist of database subscription fees paid to PricewaterhouseCoopers.

Pre-Approval Policies and Procedures

Our audit committee has adopted procedures requiring the pre-approval of all non-audit services performed by our independent registered public accounting firm in order to assure that these services do not impair the auditor’s independence. These procedures generally approve the performance of specific services subject to a cost limit for all such services. This general approval is to be reviewed, and if necessary modified, at least annually. Management must obtain the specific prior approval of the audit committee for each engagement of the independent registered public accounting firm to perform other audit-related or other non-audit services. The audit committee does not delegate its responsibility to approve services performed by the independent registered

23

public accounting firm to any member of management. Our audit committee has delegated authority to the committee chair to pre-approve any audit or non-audit service to be provided to us by our independent registered public accounting firm provided that the fees for such services do not exceed $100,000. Any approval of services by the committee chair pursuant to this delegated authority must be reported to the audit committee at the next meeting of the committee.

The standard applied by the audit committee, or the chair of the audit committee, in determining whether to grant approval of any type of non-audit service, or of any specific engagement to perform a non-audit service, is whether the services to be performed, the compensation to be paid therefore and other related factors are consistent with the independent registered public accounting firm’s independence under guidelines of the SEC and applicable professional standards. Relevant considerations include whether the work product is likely to be subject to, or implicated in, audit procedures during the audit of our financial statements, whether the independent registered public accounting firm would be functioning in the role of management or in an advocacy role, whether the independent registered public accounting firm’s performance of the service would enhance our ability to manage or control risk or improve audit quality, whether such performance would increase efficiency because of the independent registered public accounting firm’s familiarity with our business, personnel, culture, systems, risk profile and other factors, and whether the amount of fees involved, or the non-audit services portion of the total fees payable to the independent registered public accounting firm in the period would tend to reduce the independent registered public accounting firm’s ability to exercise independent judgment in performing the audit.

Pursuant to the requirements of Section 13 or 15(d) of the Securities Exchange Act of 1934, as amended, the Registrant has duly caused this Report to be signed on its behalf by the undersigned, thereunto duly authorized.
