Item 5.02 Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers

On June 25, 2026, the Compensation Committee of the Board of Directors of the SeaStar Medical Holding Corporation (the “Company”) approved retention bonuses for each of Eric Schlorff and Kevin Chung (“Executives”) in the amount set forth below, (a) one-third of which will vest and be payable on July 1, 2026, (b) one-third of which will vest and be payable on November 1, 2026, and (c) one-third of which will vest and be payable on March 1, 2027, in each case subject to continued employment through the applicable vesting date. Executives will receive an additional amount equal to 25% of each payment in shares of the Company’s common stock under the Company’s 2022 Omnibus Incentive Plan, with the number of shares being determined based on the share price at the close of business on each applicable vesting date. If an Executive departs prior to the applicable vesting date, no future payments will be made. If an Executive is separated from the Company without cause, he will receive a pro-rata amount for the then current upcoming payment. These bonuses were part of a broader retention program affecting additional long-serving Company employees. On June 29, 2026, the Company entered into a 2026 Retention Bonus Program Agreement with each of the Executives (the “Agreements’). The foregoing description of the Agreements do not purport to be complete and are qualified in their entirety by reference to the Agreements, which are filed as Exhibit 10.1 and Exhibit 10.2 to this Current Report on Form 8-K and are incorporated herein by reference.

Re: 2026 Retention Bonus Program Agreement (“Agreement”)

Dear Eric,

We appreciate your continued work and dedication as an employee of SeaStar Medical (“the Company”). As an incentive for you to stay with the Company, we would like offer you the opportunity to receive a retention bonus, in addition to your normal compensation, subject to the terms and conditions described below.

1. Retention Payment. If you meet all of the requirements described in Section 3 below, the Company will pay you a cash retention bonus in the aggregate amount of $ 200,000.00 (the “Retention Payment”), less applicable deductions and withholdings. The Retention Payment shall be divided into three installments, and will be paid as outlined in Section 3, below.

2. Restricted Stock Unit: In the discretion of the Compensation Committee of the Board of Directors of the Company, the Company may grant you a restricted stock unit award (“RSU Grant”) in an aggregate amount equal to 25% of the aggregate Retention Payment. Any such RSU Grant shall vest in three installments on the date of the Retention Periods outlined in Section 3, below. Such RSU Grant will be made pursuant to a separate award agreement, which shall be provided to you at the time of the RSU Grant if and when made. See Appendix A for an illustrative example

3. Retention Periods. You will be entitled to the following Retention Payment if you meet the eligibility requirements set forth in Section 4 and continue to be employed with the Company on the following dates (“Retention Periods”) in accordance with the following Retention Schedule:

Retention Schedule

Retention Period

Retention Payment

Through July 1, 2026

$66,666.66

Through November 1, 2026

$66,666.67

Through March 1, 2027

$66,666.67

4. Eligibility for Retention Payment. To receive the Retention Payment described in Section 1, you must meet the following requirements:

(A)

Remain employed by the Company in good standing through the applicable Retention Period set forth in the Retention Schedule.

(B)

Continue to perform your duties at an acceptable level through the applicable Retention Period set forth in the Retention Schedule.

You will not be eligible for any Retention Payment if you leave the Company prior to the end of the applicable Retention Period. However, if you are terminated from the company without Cause prior to the end of the given Retention Period, you will receive a pro-rated amount for the number of days that you were actively employed during the given Retention Period. For any Retention Period in which you were on an approved leave of absence, the Retention Bonus will be pro-rated with respect to the number of days in the Retention Period that you were not on such leave of absence.

For the purposes of this Agreement, “Cause” shall mean: (i) a material breach of any material Company policy; (ii) breach of fiduciary duties, gross negligence or willful misconduct or any act of dishonesty, theft or fraud with respect to the Company or any of its subsidiaries; (iii) indictment (or equivalent) for a serious crime (including, without limitation, a crime involving moral turpitude, embezzlement, dishonesty, theft or fraud); (v) other conduct causing the Company substantial public disgrace or disrepute or economic harm; or (vi) any act or omission that would make the continuance of your employment by the Company or any of its subsidiaries materially detrimental to the Company or such subsidiary.

5. Timing of Bonus Payment. The Retention Payment for a given Retention Period will be made on the first regularly scheduled payday following the end of Retention Period indicated in the Retention Schedule.

6. At-Will Status. This Agreement does not alter the “at-will” status of your employment, and the Company reserves the right to terminate you at anytime with or without cause. This Agreement is not a guarantee or promise of employment for any specific length of time.

7. Applicable Law. This Agreement shall be governed by the laws of the State of Colorado without regard to conflicts of law principles.
