EXHIBIT 10.25.2

SEPARATION AGREEMENT AND GENERAL RELEASE

This Separation Agreement and General Release (“Agreement”) is between Longeveron Inc. (“Company”) and Wa’el Rashad (“Employee”), together the “Parties.”

WHEREAS, the Company terminated Employee's employment effective as of Tuesday, September 9, 2025 (“Termination Date”);

WHEREAS, the terms and conditions of Employee's employment and separation are governed by the agreement entered into between the parties on or about February 21, 2023, as amended on January 17, 2025 (“Terms of Employment”), which were reviewed by counsel for Employee;

WHEREAS, the Company is willing to pay Employee certain severance in exchange for a release of claims and other commitments.

NOW THEREFORE, intending to be legally bound and for good and valuable consideration, Company and Employee agree as follows:

1.
Recitals. The foregoing recitals are true and correct and incorporated herein.
2.
Termination of Employment.
(a)
The Company timely paid or will timely pay Employee, in accordance with its normal payroll and other procedures (or as otherwise required by law), for (i) Employee’s work through the Termination Date, (ii) Employee’s accrued but unused vacation pay, and (iii) Employee’s properly reported and reimbursable business expenses, less all required tax withholdings and other deductions.
(b)
Employee’s eligibility to participate in the Company’s group insurance and other welfare benefit plans and programs ceased as of the Termination Date, except that Employee's group insurance medical benefits ceased or will cease on September 30, 2025, unless otherwise extended under COBRA.
(c)
The foregoing payments and benefits have been or will be provided to Employee regardless of whether Employee signs or revokes this Agreement.
3.
Severance. In exchange for Employee signing and not revoking this Agreement, thereby releasing any and all claims Employee has or may have against the Released Parties (as defined in Section 4(a) of this Agreement) as well as abiding by the terms of this Agreement (all as set forth in Section 4(e) of Employee's Terms of Employment), the Company will agree to pay Employee the following Separation Benefits:
(a)
The Company will continue to pay Employee at the rate of Employee’s current annual salary of Five Hundred and Eight Five Thousand Dollars ($585,000.00 (excluding bonuses, commissions, incentive payments, and any other form of supplemental

1

compensation), less all required tax withholdings and other deductions, for twelve (12) months following the Effective Date of this Agreement (“Salary Severance”). The Company will pay the Salary Severance in substantially equal installments, at least monthly, commencing on the first regular payroll date after the Effective Date of this Agreement (as defined in Section 5(b) below), but in no event later than the sixtieth (60th) day following Employee’s Termination Date. The first payment of Salary Severance shall include payment of all amounts of such severance that otherwise would have been due prior to such date (without interest), applied as though such payments commenced on the next normal pay date immediately following Employee’s Termination Date.
(b)
The Company will pay Employee a prorated portion of the incentive bonus in the amount of Two Hundred Eighty-Two Thousand, Seven Hundred Twenty-Three dollars and Twenty-Nine cents ($282,723.29) as described in the amount of Section 4(b)(iv) of Employee’s Terms of Employment (“Target Bonus Severance”). The Company will pay the Target Bonus Severance within 60 days following the Termination Date, subject to the terms of Employee’s Compensation Deferral Agreement under the Longeveron, Inc. Deferred Compensation Plan.
(c)
If Employee timely elects to continue Employee’s group health benefits under COBRA, the Company will pay Employee’s COBRA premiums for coverage for eighteen (18) months following the Termination Date so long as Employee remains eligible to receive COBRA. Thereafter, Employee must pay the full cost of Employee’s COBRA premiums to continue Employee’s COBRA coverage. 1

 

1 Be aware that if you cancel COBRA coverage in the future, then that may be deemed a voluntary relinquishment (and not a “qualifying event”) and, if so, this can delay the time when you could acquire coverage through an Affordable Care Act marketplace plan.

(d)
As of the Effective Date of this Agreement, the Company will accelerate: (i) the grant of the 79,166 unvested options from Grant Numbers ES-171 and ES-232 that must be exercised within 90 days of the Termination Date, (ii) the vesting of the Employee’s RSUs in the amount of 38,333 shares from Grant Number ES-138, (iii) the vesting of the Employee's RSUs in the amount of 7,188 shares from Grant Number ES-147, and (iv) the vesting of the Employee's RSUs in the amount of 15,000 shares from Grant Number ES-207.
(e)
The separation benefits referred to in Subparagraphs 3(a)-(d) are referred to throughout this Agreement collectively as “Severance Benefits.”
(f)
For avoidance of doubt, Employee is not entitled to any of the Severance Benefits in this Section in the event Employee fails to sign this Agreement or if Employee revokes this Agreement or if Employee fails to abide by the terms of this Agreement. The Company is also not obligated to make the payments identified in this Section in the event Employee fails to return any Company Property, including but not limited to any company vehicle, company laptop, company mobile phone, company data, and documents, regardless of the format.

Release of Claims.
(a)
Subject to Sections 4(b) and (c), Employee, on behalf of Employee and Employee's heirs and personal representatives (“Releasors”), hereby releases and forever discharges the Company, its direct and indirect subsidiaries, divisions, parents, affiliates, companies under common control of any of the foregoing, predecessors, successors, and assigns, and its and their past, present and future shareholders, partners, principals, managers, members, directors, officers, employees, agents, attorneys, insurers, employee benefit plans, trustees and all others acting in concert with them (collectively, the “Released Parties”), from any and all claims, actions, suits, proceedings, complaints, causes of action, grievances, debts, costs and expenses (including attorney’s fees), at law or in equity, known or unknown, that Employee has or may have through the date Employee signs this Agreement, arising out of, based on, or relating in any way to any acts or omissions that occurred, in whole or in part, prior to the time that Employee signs this Agreement, including, but not limited to, claims for breach of any express or implied contract, wrongful termination, retaliation, defamation of character, personal injury, intentional or negligent infliction of emotional distress, discrimination or harassment based on race, religion, sex, age, color, handicap and/or disability, national origin or any other protected class and any other claim based on or related to Employee’s employment with the Company or Employee’s departure therefrom, including, but not limited to, including, but not limited to, claims for violation of the Executive Retirement Income Security Act of 1974, Title VII of the Civil Rights Act of 1964, the Age Discrimination in Employment Act of 1967, the Older Workers’ Benefit Protection Act of 1990, the Americans with Disabilities Act, the Americans With Disabilities Act Amendments Act, the Worker Adjustment and Retraining Notification Act, the Equal Pay Act of 1963 as amended, the Ledbetter Fair Pay Act, the Civil Rights Acts of 1866, 1871 and 1991, the Immigration Reform and Control Act, the Rehabilitation Act of 1973, the Occupational Safety and Health Act of 1970, the Fair Credit Reporting Act, the Family and Medical Leave Act, the False Claims Act, the California Worker Adjustment and Retraining Notification Act; the California Occupational Safety and Health Act; the California Family Rights Act (“CFRA”); The California Fair Employment and Housing Act (“FEHA”); the California Labor Code; the California Consumer Privacy Act; the California Equal Pay and Fair Pay Act; the California Unruh Civil Rights Act; the California Ralph Civil Rights Act; the California Bane Civil Rights Act; and any other international, federal, state or local law, ordinance, Executive order, code, rule, regulation, or statute, all as amended.

Note: The claims being waived and released expressly include claims of age discrimination under the Age Discrimination in Employment Act, as amended (“ADEA”).

(b)
Notwithstanding anything in this Agreement to the contrary, the release set forth in Section 4(a) does not and is not intended to release any claims that cannot be released by law, such as claims for vested pension benefits or claims for workers' compensation benefits, or release any rights to a defense or indemnification from the Company or its insurers for actions Employee took or failed to take during the course of Employee's employment with the Company.
(c)
Notwithstanding anything in this Agreement to the contrary, the release set forth in Section 4(a) does not and is not intended to prevent, restrict or otherwise interfere with Employee's right to (i) file a charge or complaint with any appropriate federal, state or local agency or court, (ii) testify, assist, participate in, or cooperate with the investigation of any charge or

3

complaint pending before or being investigated by such agency or court, (iii) enforce this Agreement, (iv) seek a judicial determination of the validity of the release of Employee's rights under the Age Discrimination in Employment Act, or (v) report violations of any law administered by the Securities and Exchange Commission (“SEC”) or Occupational Safety and Health Administration (“OSHA”), (vi) receive any financial awards from the SEC or OSHA for reporting possible violations of federal law or regulation, (vii) make other disclosures protected under the whistleblower provisions of state or federal law or regulation, or (viii) report or disclose facts related to any unlawful activity in the workplace, including but not limited to sexual assault and harassment.
(d)
If an administrative agency or court assumes jurisdiction over any charge or complaint involving claims that are released by Section 4(a) of this Agreement, Employee hereby agrees to not, directly or indirectly, accept, recover or receive any resulting monetary damages or other equitable relief that otherwise would be due, and Employee hereby expressly waives any rights to any such recovery or relief, except as permitted by Section 4(c)(vi).
(e)
Waiver of California Civil Code Section 1542. This Agreement is intended to be effective as a general release of and bar to all claims as stated in this Section. Accordingly, the Releasors specifically waive all rights under California Civil Code Section 1542, which states, “A GENERAL RELEASE DOES NOT EXTEND TO CLAIMS THAT THE CREDITOR OR RELEASING PARTY DOES NOT KNOW OR SUSPECT TO EXIST IN HIS OR HER FAVOR AT THE TIME OF EXECUTING THE RELEASE AND THAT, IF KNOWN BY HIM OR HER, WOULD HAVE MATERIALLY AFFECTED HIS OR HER SETTLEMENT WITH THE DEBTOR OR RELEASED PARTY.” The Employee acknowledges that the Employee may later discover claims or facts in addition to or different from those which the Employee now knows or believes to exist with regards to the subject matter of this Agreement, and which, if known or suspected at the time of executing this Agreement, may have materially affected its terms. Nevertheless, the Releasors waive any and all Claims that might arise as a result of such different or additional claims or facts.
5.

Employee acknowledges and agrees that Employee received this Agreement and has up to twenty-one (21) days from the date Employee received this Agreement to consider its terms. Any changes to this Agreement during that period, whether material or not, will not extend the 21-day period. If Employee signs this Agreement, Employee may still revoke Employee's acceptance of the Agreement for up to seven (7) days after Employee signs it, by notifying the Company in writing before the expiration of that seven-day period. The written notice should be delivered in person or, if sent by mail, postmarked no later than the 7th day and mailed to: Longeveron, Attn. Paul Lehr, General Counsel, 1951 NW 7th Avenue, Suite 520, Miami, FL 33136.
(b)
If not revoked, this Agreement will become effective on the 8th day after Employee signs it. If Employee does not sign this Agreement within the 21-day period, or if Employee timely revokes this Agreement during the seven-day revocation period, this Agreement will not become effective.
