**Employment Agreements**

First Seacoast Bank has entered into employment agreements with each of Messrs. Brannen, Donovan and Dargan. The employment agreements for Messrs. Brannen and Donovan had an initial term of three years and the employment agreement for Mr. Dargan had an initial term of two years. Commencing as of March 1<sup>st</sup> of each year, the Board of Directors may renew the agreement for an additional year so that the remaining term again becomes three years for Messrs. Brannen and Donovan and two years for Mr. Dargan. In addition to base salary, the agreements provide for, among other things, participation in bonus programs and other benefit plans and arrangements applicable to executive employees. The current terms of the agreements with Messrs. Brannen and Donovan expire on March 1, 2029, and the current term of the agreement with Mr. Dargan expires on March 1, 2028. The current base salaries for Messrs. Brannen, Donovan, and Dargan are $350,000, $340,000 and $265,000, respectively. Current base salary reflects salary adjustments made after the end of fiscal year 2025. First Seacoast Bank may terminate the employment of each of the executives for cause at any time, in which event they would have no right to receive compensation or other benefits under the employment agreements for any period after their termination of employment.

Certain events resulting in an executive's termination or resignation will entitle the executive to payments of severance benefits following the termination of employment. In the event of an executive's involuntary termination for reasons other than for cause or if the executive resigns during the term of the agreement following (i) the failure to appoint the executive to the executive position set forth in the agreement or a material change in function, duties or responsibilities resulting in a reduction of the responsibility, scope, or importance of the executive's position, (ii) a relocation by more than 50 miles, (iii) a material reduction in the benefits or perquisites paid to the executive (unless the reduction is part of a reduction that is generally applicable to employees of First Seacoast Bank), (iv) a liquidation or dissolution of First Seacoast Bank or (v) a material breach of the employment agreement by First Seacoast Bank, then the executive would become entitled to a lump sum cash severance payment equal to the base salary and bonuses or incentive awards the executive would have earned for the lesser of the remaining unexpired term of the employment agreement or 24 months. In addition, the executive would become entitled, at no expense to him, to the continuation of non-taxable medical and dental coverage for the lesser of the remaining unexpired term of the employment agreement or the time at which the executive receives coverage under another employer's plan. If the health and dental coverage is not permitted by applicable law or if providing the benefits would subject First Seacoast Bank to penalties, the executive will receive a cash lump sum payment equal to the value of the benefits.

If there is a change in control of the Company or First Seacoast Bank, followed by an executive's involuntary termination other than for cause or upon the executive's resignation for one of the reasons set forth above, the executive would become entitled to a lump sum cash severance payment equal to three times the executive's "base amount," as that

------

term is defined for purposes of Internal Revenue Code Section 280G (<u>i.e.</u>, the average annual taxable income paid to him for the five taxable years preceding the taxable year in which the change in control occurs). In addition, the executive would become entitled, at no expense to him, to the continuation of non-taxable medical and dental coverage for 36 months following his termination of employment, or if the coverage is not permitted by applicable law or if providing the benefits would subject First Seacoast Bank to penalties, the executive will receive a cash lump sum payment equal to the value of the health and dental benefits.

If an executive dies, the executive's estate or beneficiaries will be paid the executive's base salary for a period of six months and the executive's dependents will be entitled to continued non-taxable medical, dental and other insurance for one year following the executive's death.

Under each employment agreement, if the executive becomes disabled within the meaning of the term under Internal Revenue Code Section 409A and as set forth in the employment agreement, he will receive benefits under any short-term or long-term disability plans maintained by First Seacoast Bank. First Seacoast Bank will make up any difference, if any, between the executive's base salary and the disability benefits for a period of one year.

Under each employment agreement, if the executive retires following his attainment of age 65, he will receive benefits under any applicable retirement or other plans maintained by First Seacoast Bank.

Upon termination of an executive's employment (other than following a change in control), the executive will be subject to certain restrictions on the executive's ability to compete or to solicit business or employees of First Seacoast Bank for a period of one year following his termination of employment.

**Salary Continuation Agreement**

First Seacoast Bank is a party to a salary continuation agreement with Mr. Brannen. Under the agreement, if he separates from service other than at or following a change in control, he will receive a fixed annual benefit of $64,817, which equals the accrued benefit determined under the agreement as of January 1, 2025. Unless Mr. Brannen becomes disabled or dies, the benefit payments will begin on the first day of the second month following his separation from service and will be paid monthly for a period of 120 months. If Mr. Brannen becomes disabled, the benefit will be paid in 120 monthly installments commencing on the first day of the month following the date he reaches age 66. Hardship distributions may also become payable under the agreement if he experiences an unforeseeable emergency.

If Mr. Brannen dies before a separation from service, his beneficiary will receive the benefit paid in a lump sum on the first day of the second month following his death. If he dies following his separation from service but before receiving benefits under the agreement, his beneficiary will receive the benefits he would have otherwise continued to have received, paid in a lump sum on the first day of the second month following his death. If Mr. Brannen dies while receiving benefits, his beneficiary will continue to receive the benefit payments (at the same time and in the same form) he would have continued to have received under the agreement.

**Employee Stock Ownership Plan**

First Seacoast Bank maintains the First Seacoast Bank Employee Stock Ownership Plan (the "ESOP"), a tax-qualified defined contribution plan for eligible employees. The named executive officers are eligible to participate in the ESOP on the same terms as other eligible employees of First Seacoast Bank.

The ESOP trustee holds the shares purchased by the ESOP in an unallocated suspense account, and shares will be released from the suspense account on a pro-rata basis as the trustee repays the loan used to purchase the shares. The trustee will allocate the shares released among participants based on each participant's proportional share of compensation relative to all participants. A participant will fully vest in his or her account balance after five years of service.

**401(k) Plan**

First Seacoast Bank maintains the First Seacoast Bank 401(k) Plan (the "401(k) Plan"), a tax-qualified defined contribution plan for eligible employees. The named executive officers are eligible to participate in the 401(k) Plan on the same terms as other eligible employees of First Seacoast Bank.

------

Under the 401(k) Plan, a participant may elect to defer, on a pre-tax basis, the maximum amount of compensation permitted by the Internal Revenue Code. In addition to salary deferral contributions, First Seacoast Bank makes safe harbor matching contributions equal to 100% of a participant's salary deferrals, up to 4% of the participant's compensation. First Seacoast Bank may also make other discretionary matching contributions and other discretionary employer contributions to the plan. A participant is always 100% vested in his or her salary deferral contributions and employer contributions under the plan.

**Equity Incentive Plans**

The Company has adopted the 2021 Equity Incentive Plan and the 2024 Equity Incentive Plan, both of which were approved by stockholders. Each one provides for the granting of incentive and non-statutory stock options to purchase shares of Company common stock and the granting of awards of restricted stock and restricted stock units.

**Outstanding Equity Awards at December 31, 2025**

The following table provides information as of December 31, 2025, regarding equity awards that are outstanding to each named executive officer.

***Supplemental Director Retirement and Fee Continuation Agreements***. First Seacoast Bank has entered into Supplemental Director Retirement Agreements with each of its non-employee directors, except Mr. Lynch with whom it has entered into a Director Fee Continuation Agreement which is substantially the same as the Supplemental Director Retirement Agreements. Under the agreements, a director who remains in service on the Board of Directors until the normal retirement age specified in the agreement (age 70) will be entitled to receive an annual retirement benefit of equal to $20,000. The payments will be made to the director upon his or her separation from service in annual installments for ten years. If a director separates from service before age 70, he or she is entitled to the vested percentage of his or her accrued liability balance under the agreement, paid in annual installments over ten years. Directors vest under their agreements over a ten-year period (0% during the first 6 years, 25% after 7 years, 50% after 8 years, 75% after 9 years and 100% after 10 years). Upon a change in control, directors receive the present value of a stream of $20,000 payments for 10 years. Upon death, a director's beneficiary will receive the vested portion of the director's accrued liability balance, paid in a lump sum within 30 days following the director's death.

***Director Deferred Fee Plan.*** First Seacoast Bank maintains a deferred directors fee plan, pursuant to which non-employee directors may elect to defer a portion of their director's fees each year. The Bank credits the deferred amounts with earnings at a rate equivalent to the yield for the 7-year Treasury Bill Rate (compounded monthly). Directors become eligible to receive their deferred fees and earnings on a separation from service or a specified date and payable in a lump sum or installments over a 5- or 10-year period, as elected by each director. If elected by a director, benefits will be paid in a lump sum if the director separates from service within two years of a change in control. Benefits are also payable upon a director's death.

**ITEM 13. <u>Certain Relationships and Relate</u><u>d Transactions, and Director Independence</u>**

**Transactions with Certain Related Persons**

***Loans and Extensions of Credit.*** Federal law generally prohibits publicly traded companies from making loans to their executive officers and directors, but it contains a specific exemption from the prohibition for loans made by federally insured financial institutions, such as First Seacoast Bank, to their executive officers and directors in compliance with federal banking regulations. At December 31, 2025, all of our loans to directors and executive officers were made in the ordinary course of business, were made on substantially the same terms, including interest rates and collateral, as those prevailing at the time for comparable loans with persons not related to First Seacoast Bank, and did not involve more than the normal risk of collectability or present other unfavorable features. At December 31, 2025, these loans were performing in accordance with their original repayment terms that were substantially similar to those prevailing at the time for comparable loans with persons not related to First Seacoast Bank and were made in compliance with federal banking regulations.

***Other Transactions.*** Neither the Company nor First Seacoast Bank has entered into any other transactions since January 1, 2025, in which the amount involved exceeded $120,000 and in which any related persons had or will have a direct or indirect material interest.

**Director Independence**

Because the Company is listed on the Nasdaq Stock Market, the Company has adopted the definition of "independent director" contained in the listing standards of the Nasdaq Stock Market when determining the independence of its directors. All of the Company's directors are considered independent under the listing standards of the Nasdaq Stock Market, except for James R. Brannen who is employed by the Company and First Seacoast Bank in his capacity as Chief Executive Officer. To the Company's knowledge, there were no other transactions between the Company and any director or entity controlled by any director, which would interfere with the director's exercise of independent judgment in carrying out his or her responsibilities as a director.

**ITEM 14. <u>Principal Accou</u><u>ntant Fees and Services</u>**

The fees that Wolf & Company, P.C. billed to the Company for the years ended December 31, 2025 and 2024 are as follows:

---

| | | |
|:---|:---|:---|
|  | **2025** | **2024** |
| Audit Fees <sup>(1)</sup> | $210000 | $175000 |
| Audit-Related Fees |  |  |
| Tax Fees |  |  |
| All Other Fees <sup>(2)</sup> | 29250 | 41000 |

---

------

(1)Consists of fees for professional services rendered for the audit of the consolidated financial statements included in the Annual Report on Form 10-K, for the review of financial statements included in the Quarterly Reports on Form 10-Q and for services normally provided by the independent registered public accounting firm in connection with statutory and regulatory filings or engagements.

(2)Consists of fees for professional services rendered in connection with WolfPAC modules.

The Audit Committee is responsible for appointing, setting compensation and overseeing the work of the independent registered public accounting firm. In accordance with its charter, the Audit Committee approves, in advance, all audit and permissible non-audit services to be performed by the independent registered public accounting firm. This approval process ensures that the independent registered public accounting firm does not provide any non-audit service to us prohibited by law or regulation.
