On December 10, 2021 a Stipulation and Agreement of Compromise, Settlement and Release (the “Settlement Agreement”) was filed in relation to a lawsuit involving Columbia Financial, Inc. (the “Company”) and certain of its current and former directors pending in the Court of Chancery of the State of Delaware entitled Pascal v. Czerwinski, et. al., C.A. No. 2020-0320-SG (the “Settlement”). The Settlement resolves a lawsuit (the “Litigation”) challenging the equity compensation granted on or about July 23, 2019 to persons who were then-directors of the Company (the “Defendants”) (collectively, “2019 Equity Grants”). The Litigation alleged, derivatively on behalf of current holders of stock of the Company, that the granting of the 2019 Equity Grants violated the directors’ fiduciary duties and sought, among other things, cancellation of the 2019 Equity Grants made to the Defendants. The Litigation further asserted class claims brought on behalf of stockholders of the Company on April 12, 2019 and their successors and assigns (the “Class”) alleging that the proxy statement disseminated to obtain stockholder approval of the Company’s 2019 Equity Incentive Plan was false and misleading, and that the stockholders’ approval of that plan was therefore legally invalid. The clams challenging the disclosures in the proxy statement were dismissed, subject to a right of appeal.

Without admitting the validity of any of the claims asserted in the Litigation, or any liability with respect thereto, and expressly denying all allegations of wrongdoing, fault, liability, or damage against the Company and the Defendants arising out of any of the conduct, statements, acts or omissions alleged, or that could have been alleged, in the Litigation, the Company and the Defendants have concluded that it is desirable that the claims be settled on the terms and subject to the conditions set forth in the Settlement Agreement. The Company and the Defendants are entering into the Settlement Agreement for settlement purposes only and solely to avoid the costs, risks, distraction, and uncertainties of continued litigation. Pursuant to the Settlement, and subject to final approval of the Settlement by the Delaware Court of Chancery, and in exchange for a release of all claims by the plaintiffs and a dismissal of the Litigation with prejudice, the Company has agreed to submit the 2019 Equity Grants to a binding vote of its stockholders at a stockholder meeting to be held in 2022 at a date to be determined that is within four months from the date of final approval of the Settlement by the Delaware Court of Chancery.

On December 15, 2021, the Delaware Court of Chancery entered an order preliminarily certifying the Class for purposes of the Settlement and providing for notice to stockholders of the final certification of the Class and of Settlement. The Court will consider whether to enter an order providing for final certification of the Class and approval of the Settlement at a hearing currently scheduled for February 7, 2022, at 11:30 a.m. The Company respectfully refers you to full copies of (a) the Settlement Agreement; (b) the Notice of Pendency of Derivative Action, Proposed Settlement, and Settlement Hearing; and (c) the Court’s Order Approving Notice of Settlement and Scheduling Settlement Approval Hearing and (d) the proposed Final Order and Judgment that the Court will be asked to enter if the Settlement is approved.. These documents are attached as exhibits to this Form 8-K, incorporated by reference herein, and are available on the Company’s website at https://ir.columbiabankonline.com/news/default.aspx. Information contained in or accessible through the Company’s website does not constitute part of, and is not incorporated into, this Current Report on Form 8-K.

The Company does not expect the Settlement and related matters, including any future award of attorney’s fees to the Plaintiff’s counsel, to have a material impact on its financial condition or results of operations.
