This is a summary of the annual report Form 5500 Annual Return/Report of Small Employee Benefit Plan of Colonial Federal Savings Bank 401(k) Plan and Employer Identification Number 04-1983105/Plan Number 003 for the plan year 01/01/2024 through 12/31/2024. The Form 5500-SF annual report has been filed with the Employee Benefits Security Administration, as required under the Employee Retirement Income Security Act of 1974 (ERISA). Your plan is a single employer, defined contribution plan with the following characteristics: ERISA section 404(c), total participant-directed account, code section 401(k) feature, code section 401(m) arrangement, total or partial participant-directed account, pre-approved pension.

The value of plan assets, after subtracting liabilities of the plan, was $10,797,596 as of the end of the plan year, compared to $8,924,326 as of the beginning of the plan year. During the plan year the plan experienced a change in its net assets of $1,873,270.

The plan had total income of $1,922,843, including employer contributions of $19,351, employee contributions of $193,501, other contributions/other income of $0 and earnings from investments of $1,709,991.

#### Information Regarding Plan Assets

The U.S. Department of Labor's regulations require that an independent qualified public accountant audit the plan's financial statements unless certain conditions are met for the audit requirement to be waived. This plan met the audit waiver conditions for the plan year beginning 01/01/2024 and therefore has not had an audit performed. Instead, the following information is provided to assist you in verifying that the assets reported on the Form 5500-SF were actually held by the plan.

At the end of the plan year, the plan had qualifying plan assets at the following institution(s):

Empower Trust Company, LLC

$10,715,668.98

The plan receives year-end statements from these regulated financial institutions that confirm the above information.

The remainder of the plan's assets were held in individual participant accounts with investments directed by participants and beneficiaries and with account statements from regulated financial institutions furnished to the participant or beneficiary at least annually and loans to participants and other qualifying assets.

Plan participants and beneficiaries have a right, on request and free of charge, to get copies of the financial institution year-end statements. If you want to examine or get copies of the financial institution year-end statements, please contact Pentegra Services Inc., the plan administrator, at 701 Westchester Avenue, Suite 320e, White Plains, NY 10604 and phone number, 866-633-4015.
