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&#8217;s beneficiary will receive the vested portion of the director&#8217;s accrued liability balance, paid in a lump sum within 30 days following the director&#8217;s death.</span></p><p style="text-indent:6.667%;font-size:10pt;margin-top:10pt;font-family:Times New Roman;margin-bottom:0;text-align:left;"><span style="color:#000000;white-space:pre-wrap;font-weight:bold;font-size:10pt;font-family:Times New Roman;font-style:italic;font-kerning:none;min-width:fit-content;">Director Deferred Fee Plan.</span><span style="color:#000000;white-space:pre-wrap;font-size:10pt;font-family:Times New Roman;font-kerning:none;min-width:fit-content;">  First Seacoast Bank maintains a deferred directors fee plan, pursuant to which non-employee directors may elect to defer a portion of their director&#8217;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&#8217;s death.</span></p><p style="font-size:10pt;margin-top:10pt;font-family:Times New Roman;margin-bottom:0;text-align:left;" id="item_12_security_ownership_certain_benef"><span style="color:#000000;white-space:pre-wrap;font-weight:bold;font-size:10pt;font-family:Times New Roman;font-kerning:none;min-width:fit-content;">ITEM 12. </span><span style="color:#000000;white-space:pre-wrap;font-weight:bold;text-decoration:underline solid;font-size:10pt;font-family:Times New Roman;font-kerning:none;min-width:fit-content;">Security Ownership of Certain Beneficial Ow</span><span style="color:#000000;white-space:pre-wrap;font-weight:bold;text-decoration:underline solid;font-size:10pt;font-family:Times New Roman;font-kerning:none;min-width:fit-content;">ners and Management and Related Stockholder Matters</span></p><div class="item-list-element-wrapper" style="margin-left:6.667%;display:flex;margin-top:10pt;justify-content:flex-start;align-items:baseline;margin-bottom:0;min-width:3.333%;text-align:left;"><span style="color:#000000;white-space:pre-wrap;font-size:10pt;font-family:Times New Roman;font-kerning:none;min-width:3.571084182443509%;word-break:keep-all;display:inline-flex;justify-content:flex-start;">(a)</span><div style="display:inline;"><span style="color:#000000;white-space:pre-wrap;font-size:10pt;font-family:Times New Roman;font-kerning:none;min-width:fit-content;">Securities Authorized for Issuance Under Stock-Based Compensation Plans</span></div></div><p style="text-indent:6.667%;font-size:10pt;margin-top:10pt;font-family:Times New Roman;margin-bottom:0;text-align:left;"><span style="color:#000000;white-space:pre-wrap;font-size:10pt;font-family:Times New Roman;font-kerning:none;min-width:fit-content;">The following information is presented for the First Seacoast Bancorp, Inc. 2024 Equity Incentive Plan as of December 31, 2025:</span></p><p style="text-indent:6.667%;font-size:10pt;margin-top:0;font-family:Times New Roman;margin-bottom:0;text-align:left;"><span style="white-space:pre-wrap;font-size:10pt;font-family:Times New Roman;font-kerning:none;min-width:fit-content;">&#160;</span></p>

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.</span></p><p style="text-indent:6.667%;font-size:10pt;margin-top:10pt;font-family:Times New Roman;margin-bottom:0;text-align:left;"><span style="color:#000000;white-space:pre-wrap;font-weight:bold;font-size:10pt;font-family:Times New Roman;font-style:italic;font-kerning:none;min-width:fit-content;">Other Transactions.</span><span style="color:#000000;white-space:pre-wrap;font-size:10pt;font-family:Times New Roman;font-kerning:none;min-width:fit-content;">  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.</span><span style="color:#000000;white-space:pre-wrap;font-size:10pt;font-family:Times New Roman;font-kerning:none;min-width:fit-content;"> </span></p><p style="font-size:10pt;margin-top:10pt;font-family:Times New Roman;margin-bottom:0;text-align:left;"><span style="color:#000000;white-space:pre-wrap;font-weight:bold;font-size:10pt;font-family:Times New Roman;font-kerning:none;min-width:fit-content;">Director Independence</span></p><p style="text-indent:6.667%;font-size:10pt;margin-top:10pt;font-family:Times New Roman;margin-bottom:0;text-align:left;"><span style="color:#000000;white-space:pre-wrap;font-size:10pt;font-family:Times New Roman;font-kerning:none;min-width:fit-content;">Because the Company is listed on the Nasdaq Stock Market, the Company has adopted the definition of &#8220;independent director&#8221; contained in the listing standards of the Nasdaq Stock Market when determining the independence of its directors.
