URSBBancorp, Inc. Announces Expected Closing Date of Initial Public Offering

Carteret, NJ; March 20, 2026 – URSB Bancorp, Inc. (the “Company”), the proposed holding company of United Roosevelt Savings Bank (the “Bank”), announced today that all final regulatory approvals have been received to complete its initial public offering in connection with the mutual-to-stock conversion of United Roosevelt, MHC (the “MHC”), the Bank’s mutual holding company. At a Special Meeting of Depositors held on February 26, 2026, the Bank’s depositors approved the MHC’s Plan of Conversion and the establishment and funding of a charitable foundation in connection with the conversion transaction.

The conversion transaction is expected to close on March 26, 2026. The Company’s common stock is expected to begin quotation the OTCQB Market on March 27, 2026 (trading symbol pending).

The Company intends to sell 2,314,375 shares of common stock, which includes 186,750 shares to be sold to the Bank’s Employee Stock Ownership Plan, for gross offering proceeds (before deducting offering expenses) of approximately $23.1 million based on the offering price of $10.00 per share. The Company also intends to contribute 20,000 shares of common stock to URSB Charitable Foundation, Inc., to be established and funded in connection with the conversion transaction. The Company expects to have 2,334,375 shares of common stock issued and outstanding upon closing of the transaction.

As previously reported, the Company conducted a Subscription Offering, which was oversubscribed in the third priority category by the Bank’s supplemental eligible account holders as of the close of business on December 31, 2025. Valid subscription orders for more than the $23,143,750 adjusted maximum of the offering range were received. As a result of the oversubscription, the subscription orders are subject to the priorities and allocation procedures disclosed in the Company’s Prospectus dated January 9, 2026. Subscribers wishing to confirm their subscription orders may do so by calling the Stock Information Center at 1-(866) 344-7952 (toll-free).

Pacific Stock Transfer Company, the Company’s transfer agent, plans to mail Direct Registration System (“DRS”) Book-Entry statements for the shares purchased in the Subscription Offering, and refund and interest checks, on or about March 27, 2026.
