Columbia Financial, Inc. Announces the Results of Its Offering; Final Merger Consideration; and Anticipated Closing Date

FAIR LAWN, N.J., July 16, 2026 (GLOBE NEWSWIRE) — Columbia Financial, Inc. (the “Company”), a Maryland corporation and the proposed successor to Columbia Financial, Inc. (Nasdaq Global Select Market: CLBK), a Delaware corporation and the mid-tier holding company for Columbia Bank (the “Holding Company” or “Columbia”), announced today that it has completed its firm commitment underwritten offering in connection with Columbia’s second-step conversion. As a result of the firm commitment underwritten offering and the recently completed subscription offering, the Company expects to sell 167,236,353 shares of its common stock at a purchase price of $10.00 per share for total offering proceeds of $1.67 billion.

Orders for a total of 52,291,781 shares at a purchase price of $10.00 per share have been accepted in the firm commitment underwritten offering, for which Keefe, Bruyette & Woods, Inc., A Stifel Company, served as the lead-left book running manager, Piper Sandler & Co. acted as co-book running manager and Brean Capital, LLC acted as co-manager. The Company received orders for 114,944,572 shares in the subscription offering portion of its second-step conversion, for which Keefe, Bruyette & Woods, Inc., A Stifel Company, acted as selling agent, including 5,017,091 shares subscribed for by the Company’s ESOP. Existing shares of the Holding Company common stock held by the minority shareholders will be exchanged for 2.2000x shares of Company common stock. Cash in lieu of fractional shares will be paid at a rate of $10.00 per share.  

The Company also announced that, immediately upon completion of the conversion, it expects to complete the acquisition of Northfield Bancorp Inc. Based on the final valuation report of the independent appraiser, Northfield stockholders will receive either $14.25 in cash or 1.425 shares of Company common stock for each share of Holding Company common stock, or a combination thereof, subject to the elections they made and proration procedures, for aggregate merger consideration of $580 million. For Northfield stockholders who did not make an election (“non-election shares”), such stockholders will receive a mix of cash and Company common stock for the non-election shares of Northfield common stock held by such stockholders based on the proration procedures in the Agreement and Plan of Merger, which will result in final aggregate merger consideration of 70% stock and 30% cash. As previously announced, the election deadline for Northfield stockholders was 5:00 p.m., New York time, on Friday, July 10, 2026.

The transactions are scheduled to close on July 20, 2026, at which time Columbia Bank MHC will cease to exist, the Company will become a fully public company and the Northfield merger will have been completed. The shares of common stock sold in the offering and issued in the exchange and the shares of Company stock issued as merger consideration are expected to begin trading on the Nasdaq Global Select Market on July 21, 2026 under the symbol “CLBK”.

Examples of forward-looking statements include, but are not limited to, statements regarding the outlook and expectations of Columbia and Northfield, respectively, with respect to the proposed transaction, the strategic benefits and financial benefits of the proposed transaction, including the expected impact of the proposed transaction on the combined company’s future financial performance (including anticipated accretion to earnings per share, the tangible book value earn-back period and other operating and return metrics), the timing of the closing of the proposed transaction, and the ability to successfully integrate the combined businesses. Such statements are often characterized by the use of qualified words (and their derivatives) such as “may,” “will,” “anticipate,” “could,” “should,” “would,” “believe,” “contemplate,” “expect,” “estimate,” “continue,” “plan,” “project” and “intend,” as well as words of similar meaning or other statements concerning opinions or judgment of Columbia or Northfield or their respective management about future events.

Forward-looking statements are based on assumptions as of the time they are made and are subject to risks, uncertainties and other factors that are difficult to predict with regard to timing, extent, likelihood and degree of occurrence, which could cause actual results to differ materially from anticipated results expressed or implied by such forward-looking statements. Such risks, uncertainties and assumptions, include, among others, the following: (i) the outcome of any legal proceedings that may be instituted against Columbia or Northfield; (ii) the possibility that the anticipated benefits of the proposed transaction, including anticipated cost savings and strategic gains, are not realized when expected or at all, including as a result of changes in, or problems arising from, general economic and market conditions, interest and exchange rates, monetary policy, laws and regulations and their enforcement, and the degree of competition in the geographic and business areas in which Columbia and Northfield operate; (iii) the possibility that the integration of the two companies may be more difficult, time-consuming or costly than expected; (iv) the impact of purchase accounting with respect to the proposed transaction, or any change in the assumptions used regarding the assets acquired and liabilities assumed to determine their fair value and credit marks; (v) the diversion of management’s attention from ongoing business operations and opportunities; (vi) potential adverse reactions of Columbia’s or Northfield’s customers or changes to business or employee relationships, including those resulting from the completion of the proposed transaction; (vii) a material adverse change in the financial condition of Columbia or Northfield; (vii) changes in Columbia’s or Northfield’s share price before closing; (viii) risks relating to the potential dilutive effect of shares of Columbia’s common stock to be issued in the proposed transaction; (ix) general competitive, economic, political and market conditions, including the impact of any potential government shutdown; (x) major catastrophes such as earthquakes, floods or other natural or human disasters, including infectious disease outbreaks; and (xi) other factors that may affect future results of Columbia or Northfield, including, among others, changes in asset quality and credit risk; the imposition of tariffs and any retaliatory responses; the inability to sustain revenue and earnings growth; changes in interest rates; deposit flows; inflation; customer borrowing, repayment, investment and deposit practices; the impact, extent and timing of technological changes; capital management activities; and other actions of the Federal Reserve Board and legislative and regulatory actions and reforms.

These factors are not necessarily all of the factors that could cause Columbia’s, Northfield’s or the combined company’s actual results, performance or achievements to differ materially from those expressed in or implied by any of the forward-looking statements. Other factors, including unknown or unpredictable factors, also could harm Columbia’s, Northfield’s or the combined company’s results.

Although each of Columbia and Northfield believes that its expectations with respect to forward-looking statements are based upon reasonable assumptions based on its existing knowledge of its business and operations, there can be no assurance that actual results of Columbia or Northfield will not differ materially from any projected future results expressed or implied by such forward-looking statements. Additional factors that could cause results to differ materially from those described above can be found in Columbia’s most recent annual report on Form 10-K for the fiscal year ended December 31, 2025, quarterly reports on Form 10-Q, and other documents subsequently filed by Columbia with the Securities Exchange Commission (the “SEC”), and in Northfield’s most recent annual report on Form 10-K for the fiscal year ended December 31, 2025, and its other filings with the SEC and quarterly reports on Form 10-Q, and other documents subsequently filed by Northfield with the SEC. The actual results anticipated may not be realized or, even if substantially realized, they may not have the expected consequences to or effects on Columbia, Northfield or each of their respective businesses or operations.
