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 occurrence of any event, change or other circumstances that could give rise to the right of one or both of the parties to terminate the merger agreement; (ii) the failure to obtain necessary regulatory approvals (and the risk that such approvals may result in the imposition of conditions that could adversely affect the combined company or the expected benefits of the proposed transaction) and the possibility that the proposed transaction does not close when expected or at all because required regulatory approvals, the approval by Columbia’s and/or Northfield’s stockholders, or other approvals and the other conditions to closing are not received or satisfied on a timely basis or at all; (iii) the outcome of any legal proceedings that may be instituted against Columbia or Northfield; (iv) 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; (v) the possibility that the integration of the two companies may be more difficult, time-consuming or costly than expected; (vi) Columbia’s ability to successfully complete its second step conversion; (vi) the possibility that the final independent appraisal of Columbia will differ from the preliminary independent appraisal of Columbia; (viii) 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; (ix) the possibility that the proposed transaction may be more expensive or take longer to complete than anticipated, including as a result of unexpected factors or events; (x) the diversion of management’s attention from ongoing business operations and opportunities; (xi) potential adverse reactions of Columbia’s or Northfield’s customers or changes to business or employee relationships, including those resulting from the announcement or completion of the proposed transaction; (xii) a material adverse change in the financial condition of Columbia or Northfield; (xiii) changes in Columbia’s or Northfield’s share price before closing; (xiv) risks relating to the potential dilutive effect of shares of Columbia’s common stock to be issued in the proposed transaction; (xv) general competitive, economic, political and market conditions, including the impact of any potential government shutdown; (xvi) major catastrophes such as earthquakes, floods or other natural or human disasters, including infectious disease outbreaks; and (xvii) 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.

Investors are cautioned not to rely too heavily on any such forward-looking statements. Columbia and Northfield urge you to consider all of these risks, uncertainties and other factors carefully in evaluating all such forward-looking statements made by Columbia and Northfield.
