## Exhibit 99.1

**COLUMBIA FINANCIAL, INC.** 

**ANNOUNCES COMMENCEMENT OF SECOND-STEP CONVERSION OFFERING; RECEIPT OF REGULATORY APPROVALS FOR THE CONVERSION AND THE ACQUISITION OF NORTHFIELD BANCORP, INC.** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**Fair Lawn, New Jersey** (May 11, 2026): Columbia Financial, Inc. ("Columbia Financial") (NASDAQ: CLBK), the mid-tier holding company for Columbia Bank (the "Bank"), announced today that on or about May 21, 2026 Columbia Financial, Inc., a newly formed Maryland corporation and the proposed successor holding company of the Bank ("Columbia Financial, Inc."), expects to commence its offering of common stock in connection with the proposed conversion of Columbia Bank MHC (the "MHC") from the mutual holding company to the stock holding company form of organization.

Columbia Financial, Inc., Columbia Financial and the MHC have received all requisite regulatory approvals and authorizations to commence the offering. In addition, Columbia Financial, Inc. and Columbia Bank have received conditional approval of the Board of Governors of the Federal Reserve System and the Office of the Comptroller of the Currency to acquire Northfield Bancorp, Inc., Woodbridge, New Jersey ("Northfield") and Northfield Bank immediately upon completion of the second-step conversion.

Columbia Financial, Inc. is offering for sale, on a best efforts basis, up to 192,625,000 shares of its common stock at a purchase price of $10.00 per share. The shares will be offered for sale in a subscription offering to eligible depositors and certain borrowers of the Bank and to the Bank's employee stock ownership plan. Any shares of common stock not purchased in the subscription offering may be offered for sale to the general public in a community offering, with a preference first given to natural persons residing in Bergen, Burlington, Camden, Essex, Gloucester, Middlesex, Monmouth, Morris, Passaic, Somerset and Union Counties in New Jersey and then to existing stockholders of Columbia Financial (other than Columbia Bank MHC) and to the general public. Columbia Financial, Inc. will also offer shares of common stock not purchased in the subscription offering and community offering, if any, in a firm commitment underwritten offering.

All questions concerning the conversion and stock offering or requests for stock offering materials should be directed to the Stock Information Center at (844) 265-9680 (toll-free). The Stock Information Center will be open Monday through Friday between 10:00 a.m. and 4:00 p.m., Eastern time, beginning on May 22, 2026. The Stock Information Center will be closed on bank holidays.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Columbia Financial, Inc. must sell at least 142,375,000 shares of its common stock in the offering in order to complete the conversion and offering. If Columbia Financial, Inc. does not receive orders for at least 142,375,000 shares of common stock in the offering, shares that Columbia Financial, Inc. issues to stockholders of Northfield in connection with the acquisition of Northfield can be counted to reach the minimum number of shares sold in the offering. Completion of the conversion and offering is also subject to the approvals of the stockholders of Columbia Financial and the members of the MHC, and the satisfaction of other customary closing conditions.

Keefe Bruyette & Woods, Inc., *A Stifel Company*, is acting as marketing agent for the subscription and community offerings and the lead left book-running manager for any firm commitment underwritten offering conducted by Columbia Financial, Inc. in connection with the second-step conversion.

Kilpatrick Townsend & Stockton LLP is serving as legal counsel to Columbia Financial, Inc., Columbia Financial, the MHC and the Bank. Nutter McClennen & Fish LLP is serving as legal counsel to Keefe Bruyette & Woods, Inc.
