Audit Committee

Our Audit Committee is composed of three directors: Messrs. Ricks, Holmen and Humer.

The Board reviews the Nasdaq Stock Market (“Nasdaq”) listing standards definition of independence for Audit Committee members on an annual basis and has determined that all members of the Audit Committee are independent (as independence is currently defined in Rule 5605(c)(2)(A)(i) and (ii) of the Nasdaq listing standards and under Rule 10A-3 under the Exchange Act).

The Board has also determined that Mr. Ricks qualifies as an “audit committee financial expert,” as defined in applicable SEC rules. The Board made a qualitative assessment of Mr. Ricks’ level of knowledge and experience based on a number of factors, including his formal education and experience as a chief financial officer for public reporting companies.

In addition, shareholders who intend to solicit proxies in support of director nominees other than our nominees must also comply with the additional requirements of Rule 14a-19(b).

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, principal financial officer, principal accounting officer or controller, or persons performing similar functions. Our code of business conduct and ethics is available under the Corporate Governance section of our website at www.senseibio.com. The nominating and corporate governance committee is responsible for overseeing the Code of Conduct and must approve any waivers of the Code of Conduct for executive officers and directors. If we make any substantive amendments to the Code of Conduct or grants any waiver from a provision of the Code of Conduct to any executive officer or director, we will promptly disclose the nature of the amendment or waiver on our website. The reference to our website address does not constitute incorporation by reference of the information contained at or available through our website, and you should not consider it to be a part of this Amendment or the Form 10-K.

Section 16(a) Beneficial Ownership Reporting Compliance

Section 16(a) of the Exchange Act requires our directors and officers and holders of more than 10% of our common stock to file with the SEC initial reports of ownership of our common stock and other equity securities on a Form 3 and reports of changes in such ownership on a Form 4 or Form 5. Directors and officers and holders of 10% of our common stock are required by SEC regulations to furnish us with copies of all Section 16(a) forms they file.

To our knowledge, based solely on a review of our records and representations made by our directors and officers and certain of our more than 10% stockholders regarding their filing obligations, we believe that during the year ended December 31, 2022, our directors, executive officers and more than 10% stockholders complied with all applicable Section 16(a) filing requirement, other than one Form 4 that was filed late on February 8, 2022 by each of Cambrian BioPharma, Inc. and Dr. Peyer, one Form 4 that was filed late on July 19, 2022 by Apeiron Investment Group Ltd. and one amendment to a Form 4 that was filed on September 1, 2022 to amend a Form 4 previously filed on February 17, 2022 to correct the number of shares owned by Robert Pierce, our former Chief R&D Officer.

Narrative to the Summary Compensation Table

We review compensation annually for all employees, including our executive officers. In setting executive base salaries and bonuses and granting equity incentive awards, we consider compensation for comparable positions in the market, the historical compensation levels of our executives, individual 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. Our Compensation Committee generally strives to set cash compensation at approximately the 50th percentile of our peer company data for comparable positions and total equity award value between the 50th and 75th percentile, though variations on this pay positioning may occur from year to year.

The Compensation Committee has historically determined our executives’ compensation. Our Compensation Committee typically reviews and discusses management’s proposed compensation with the Chief Executive Officer for all executives other than the Chief Executive Officer. Based on those discussions and its discretion, the Compensation Committee then, without members of management present, discusses and ultimately approves the compensation of our executive officers.

Annual Base Salary

Our named executive officers receive a base salary to compensate them for services rendered to us. The base salary payable to each named executive officer is intended to provide a fixed component of compensation reflecting the executive’s skill set,

experience, role and responsibilities. Mr. Celebi’s annual base salary was $500,000 from January 1, 2022 to February 28, 2022 and was $515,000 from March 1, 2022 to December 31, 2022. Ms. Colgan’s annual base salary, which was adjusted in connection with her appointment to Chief Financial Officer effective January 2022, was $410,000 at all relevant dates in 2022. Dr. van der Horst’s annual base salary was $325,000 from January 1, 2022 to December 6, 2022 and $350,000 from December 7, 2022 to December 31, 2022 (with such increase approved in connection with his promotion to Chief Scientific Officer). Dr. Pierce's annual base salary was $450,000 at all relevant dates in 2022.

Annual Bonus

We seek to motivate and reward our executives for achievements relative to our corporate goals and expectations and individual performance for each fiscal year. Our named executive officers are eligible to receive annual bonuses of up to a percentage of the applicable executive’s gross base salary based on performance metrics, as determined by our board of directors. For 2022, the target bonus for each of Mr. Celebi, Ms. Colgan and Dr. van der Horst was 55%, 40% and 35%, respectively, of their respective base salaries. Dr. Pierce’s target bonus was 40%, but he did not receive a bonus for 2022 because his employment ended during 2022. For 2023, the target bonus for Mr. Celebi is 55% and for each of Ms. Colgan and Dr. van der Horst is 40% of their respective base salaries. Dr. van der Horst’s target bonus percentage was increased in 2023 compared to 2022 as a result of his promotion to Chief Scientific Officer.

The actual performance-based annual bonus paid, if any, has historically been calculated by multiplying the executive’s annual base salary, target bonus percentage, the percentage attainment of the corporate goals established by the Board or Compensation Committee for such year, and the percentage attainment of individual goals. However, the Compensation Committee is not required to calculate bonuses in this manner and retains discretion in the amounts it awards and the factors it takes into consideration in determining bonus amounts. After the end of the year, the Compensation Committee reviews our performance against our goals and approves the extent to which our executives achieved each of our corporate and individual goals, as applicable, and, for each named executive officer, the amount of the bonus awarded.

Our 2022 corporate goals consisted of research and development, business development and financial objectives. In early 2023, the Compensation Committee determined that the 2022 corporate goals were achieved at a 80.5% level. After considering the achievement of the 2022 corporate goals together with individual goals where applicable, the Compensation Committee awarded Mr. Celebi, Ms. Colgan and Dr. van der Horst 80.5%, 80.5% and 84.5% of their target bonuses, respectively, for the year ended December 31, 2022. The actual bonus amounts paid are reflected in the “Non-Equity Incentive Plan Compensation” column of the Summary Compensation Table above.

In connection with the approval of annual bonuses for the achievement of 2022 corporate goals, the Compensation Committee approved a one-time deviation in the method of payment of annual bonuses, pursuant to which certain members of our management team, including our named executive officers, were paid one-third of their annual bonuses in the form of RSUs in lieu of cash. The Compensation Committee approved this change in line with the belief that equity awards provide our executives with a strong link to our long-term performance, create an ownership culture, and help to align the interests of our executives and stockholders. In addition, awarding a portion of the annual bonuses in equity is anticipated to help preserve our cash for the continued development of our pipeline. The Compensation Committee effected this change for the 2022 performance period only.

Accordingly, the Compensation Committee approved the following annual bonuses for 2022 for the Company’s named executive officers, which are based on a partial achievement of 2022 corporate goals:

						Number of Shares of Common Stock
Name		Cash (2/3 of Total Bonus)				underlying RSUs (1/3 of Total Bonus)
John Celebi		$	152,771				51,893
Erin Colgan		$	88,453				30,046
Edward van der Horst, Ph.D.		$	69,374				23,565

The RSUs were fully vested as of the grant date, February 15, 2023, and granted pursuant to the standard form of RSU grant notice and award agreement in substantially the form previously approved by the Board.

Termination or Change in Control Benefits

Our named executive officers may become entitled to certain benefits in connection with a qualifying termination. Each of our named executive officers’ employment agreements entitles them to certain benefits, upon a qualifying termination. For additional discussion, please see “Employment Agreements with our Named Executive Officers.”

Health and Welfare; Perquisites

All of our current named executive officers are eligible to participate in our employee benefit plans, including our medical, dental, vision, disability and life insurance plans, in each case on the same basis as all of our other employees. We generally do not

6

provide perquisites or personal benefits to our named executive officers, except in limited circumstances (including Mr. Celebi’s housing and vehicle allowances and the housing allowance provided to Dr. Pierce during his employment with us).

401(k) Plan

We maintain a safe harbor 401(k) plan that provides eligible U.S. employees with an opportunity to save for retirement on a tax advantaged basis. Eligible employees are able to defer eligible compensation up to certain limits of the Internal Revenue Code (the "Code"), which are updated annually. We have the ability to make matching and discretionary contributions to the 401(k) plan. Currently, we make matching contributions or discretionary contributions to the 401(k) plan up to a maximum of 4% of such employee’s annual compensation. The 401(k) plan is intended to be qualified under Section 401(a) of the Code, with the related trust intended to be tax exempt under Section 501(a) of the Code. As a tax-qualified retirement plan, contributions to the 401(k) plan are deductible by us when made, and contributions and earnings on those amounts are not generally taxable to the employees until withdrawn or distributed from the 401(k) plan.

Employment Agreements with our Named Executive Officers

Below are descriptions of our employment agreements with our named executive officers. The agreements generally provide for at-will employment and set forth the named executive officer’s initial base salary, eligibility for employee benefits and severance benefits upon a qualifying termination of employment. Furthermore, each of our named executive officers has executed a form of our standard proprietary information and inventions assignment agreement. The key terms of the employment agreements with our named executive officers, including potential payments upon termination or change of control, are described below.

Employment Agreements

We have entered into employment agreements with our named executive officers, which for Mr. Celebi became effective upon the closing of our initial public offering. Our employment agreement with Ms. Colgan was most recently amendedted effective January 1, 2022 in connection with her appointment as our Chief Financial Officer. Our employment agreement with Dr. van der Horst was most recently amended and restated effective December 7, 2022 in connection with his appointment as our Chief Scientific Officer. The agreements generally provide for at-will employment and set forth the named executive officer’s base salary, target bonus and eligibility for employee benefits and severance benefits upon a qualifying termination of employment.

The employment agreements provide that, subject to certain conditions and limitations, upon the termination of the employment of an eligible executive officer without Cause or resignation for Good Reason (each, as defined in the employment agreements) not in connection with a Change in Control (as defined in each employment agreement):

	•		Mr. Celebi will be eligible to receive a cash severance benefit equal to 12 months’ base salary; Ms. Colgan and Dr. van der Horst will be eligible to receive a cash severance benefit equal to nine months’ base salary; and

	•		each executive officer shall be eligible to receive COBRA premiums for the applicable length of the severance period as described above.

In addition, the employment agreements provide that, subject to certain conditions and limitations, upon the termination of the employment of an eligible executive officer without Cause or resignation for Good Reason (each, as defined in the employment agreements) within 12 months following a Change in Control:

	•		Mr. Celebi will be eligible to receive a cash severance benefit equal to 18 months’ base salary and 150% of his target bonus; Ms. Colgan and Dr. van der Horst will be eligible to receive a cash severance benefit equal to 12 months’ base salary and 100% of the officer’s target bonus;

	•		such executive officer shall be eligible to receive COBRA premiums for the applicable length of the severance period as described above; and

 

	•		all unvested equity awards held by such executive officer will become immediately vested and fully exercisable.

 

The severance benefits described above are conditioned upon the executive officer’s execution and non-revocation of a separation agreement, including a release of claims, and compliance with certain restrictive covenants.

Severance Benefits for Dr. Pierce

Our employment agreement with Dr. Pierce became effective upon the closing of our initial public offering. In December 2022, we notified Dr. Pierce that his employment as Chief R&D Officer of the Company would terminate, effective as of December 7, 2022. In accordance with his employment agreement, contingent upon Dr. Pierce’s execution of a separation agreement, including a release of claims and compliance with certain restrictive covenants, Dr. Pierce was provided severance benefits consisting of an amount equal to Dr. Pierce’s then-current salary for nine months and continued COBRA premiums for nine months.

Consulting Agreement with Dr. Pierce

In addition to the above, in connection with Dr. Pierce's separation of employment he agreed to serve as a consultant for the Company, effective December 7, 2022. In connection therewith, we entered into a consulting agreement with Dr. Pierce’s consulting entity, pursuant to which Dr. Pierce provides consulting services to the Company (the “Consulting Agreement”), including the following compensation terms: (i) a 6-month cash retainer at $12,800 per month for up to 32 hours of consulting services per month, with an hourly rate of $400 per hour if the consulting services exceed 32 hours (the “Retainer Period”), (ii) an hourly rate of $500 per hour for up to 8 hours of consulting services per week following the Retainer Period and (iii) continued vesting of outstanding equity awards held by Dr. Pierce during the term of the Consulting Agreement, and an extension of the exercise period for Dr. Pierce’s outstanding stock options (as of the effective date of the Consulting Agreement, and to the extent then-vested and that subsequently become vested) to the latter of (A) December 7, 2025 or (B) until such time as provided for in the applicable equity plan and Dr. Pierce’s applicable option award agreement.

Equity-Based Incentive Awards

We believe that equity awards provide our 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. We believe that our equity awards are an important retention tool for our executive officers, as well as for our other employees.

We award equity awards broadly to our employees. Grants to our executives and other employees are made at the discretion of our board of directors and Compensation Committee.

Prior to 2022, we only used stock option grants for this purpose because we believed they are an effective means by which to align the long-term interests of our executive officers with those of our stockholders. The use of stock options also can provide tax and other advantages to our executive officers relative to other forms of equity compensation.

Beginning in 2022, we introduced a mix of RSUs and stock options for compensating our employees. In January 2022, Mr. Celebi, Ms. Colgan, Dr. van der Horst and Dr. Pierce were granted annual equity grants consisting of 53,900, 21,000, 21,000 and 21,000 RSUs, respectively, and stock options to purchase 161,600 shares, 62,000 shares, 44,000 shares and 62,000 shares, respectively, each effective as of February 15, 2022. The RSUs vest in four equal installments on February 15, 2023, February 15, 2024, February 15, 2025 and February 15, 2026, subject to the officer’s continuous service as of the applicable vesting date. One-fourth of the shares underlying the stock options vest on February 15, 2023, with the remainder vesting monthly over the remaining 36 months.

For additional information about equity grants made historically to our named executive officers, please see “—Outstanding Equity Awards as of December 31, 2022” below.

Indemnification Agreements

Our amended and restated certificate of incorporation contains provisions limiting the liability of directors, and our amended and restated bylaws provides that we will indemnify each of our directors and officers to the fullest extent permitted under Delaware law. Our amended and restated certificate of incorporation and amended and restated bylaws also provide our board of directors with discretion to indemnify our employees and other agents when determined appropriate by the board. In addition, we have entered into an indemnification agreement with each of our directors and executive officers, which requires us to indemnify them.

Policies and Procedures for Related Person Transactions

Our board of directors has adopted a written related person transaction policy setting forth the policies and procedures for the review and approval or ratification of related-person transactions. This policy covers, with certain exceptions set forth in Item 404 of Regulation S-K under the Securities Act, any transaction, arrangement or relationship, or any series of similar transactions, arrangements or relationships in which we were or are to be a participant, where the amount involved exceeds $120,000 and a related person had or will have a direct or indirect material interest, including, without limitation, purchases of goods or services by or from the related person or entities in which the related person has a material interest, indebtedness, guarantees of indebtedness and employment by us of a related person. In reviewing and approving any such transactions, our Audit Committee is tasked to consider all relevant facts and circumstances, including whether the transaction is on terms comparable to those that could be obtained in an arm’s length transaction and the extent of the related person’s interest in the transaction. The transactions described in this section occurred prior to the adoption of this policy or were approved and/or ratified by our Audit Committee in accordance with our related person transaction policy.

Independence of the Board of Directors

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 the board of directors. Our board of directors consults with our counsel to ensure that the 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.

Our board of directors has undertaken a review of the independence of the directors and considered whether any director has a material relationship with us that could compromise his or her ability to exercise independent judgment in carrying out his or her responsibilities. Based upon information requested from and provided by each director concerning such director’s background, employment and affiliations, including family relationships, our board of directors determined that all of our directors except for Mr. Celebi, representing eight of our nine directors, are “independent directors” as defined under current rules and regulations of the SEC and the listing standards of the Nasdaq Stock Market. In making these determinations, our board of directors considered the current and prior relationships that each non-employee director has with our company and all other facts and circumstances that our board of directors deemed relevant in determining their independence.

In addition, each of the members of each of the Audit Committee, the Compensation Committee and the Nominating and Corporate Governance Committee are independent, as determined in accordance with the applicable independence requirements for such committee.

Pre-Approval Policies and Procedures

The Audit Committee has adopted a policy and procedures for the pre-approval of audit and non-audit services rendered by the Company’s independent auditors, Deloitte & Touche LLP. The Audit Committee generally pre-approves specified services in the defined categories of audit services, audit-related services and tax services up to specified amounts. Pre-approval may also be given as part of the Audit Committee’s approval of the scope of the engagement of the independent auditor or on an individual, explicit, case-by-case basis before the independent auditor is engaged to provide each service. The pre-approval of services may be delegated to one or more of the Audit Committee’s members, but the decision must be reported to the full Audit Committee at its next scheduled meeting.

All of the services of Deloitte & Touche LLP for the years ended December 31, 2022 and 2021 described above were pre-approved in accordance with the Audit Committee Pre-Approval Policy.
