These forward-looking statements include, but are not limited to, statements regarding the proposed transaction between OceanFirst and Flushing and the proposed investment by Warburg, including statements as to the expected timing, completion and effects of the proposed transaction. These statements are based on various assumptions, whether or not identified in this Current Report on Form 8-K, and on the current expectations of OceanFirst’s and Flushing’s management and are not predictions of actual performance, and, as a result, are subject to risks and uncertainties. These forward-looking statements are provided for illustrative purposes only and are not intended to serve as, and must not be relied on by any investor as, a guarantee, an assurance, a prediction or a definitive statement of fact or probability.

The forward-looking statements are intended to be subject to the safe harbor provided by Section 27A of the Securities Act of 1933, as amended, Section 21E of the Securities Exchange Act of 1934, as amended, and the Private Securities Litigation Reform Act of 1995.

These forward-looking statements are subject to a number of risks and uncertainties, including, but not limited to: (i) the risk that the proposed transaction may not be completed in a timely manner or at all; (ii) the failure to satisfy the conditions to the consummation of the proposed transaction, including obtaining the necessary regulatory approvals (and the risk that such regulatory approvals may result in the imposition of conditions that could adversely affect the combined company or the expected benefits of the transaction); (iii) the occurrence of any event, change or other circumstance that could give rise to the termination of the merger agreement between OceanFirst and Flushing; (iv) the inability to obtain alternative capital in the event it becomes necessary to complete the proposed transaction; (v) the effect of the announcement or pendency of the proposed transaction on OceanFirst’s and Flushing’s business relationships, operating results and business generally; (vi) risks that the proposed transaction disrupts current plans and operations of OceanFirst and Flushing; (vii) potential difficulties in retaining OceanFirst and Flushing customers and employees as a result of the proposed transaction; (viii) OceanFirst’s and Flushing’s estimates of its financial performance; (ix) changes in general economic, political, or industry conditions, including persistent inflation, supply chain issues or labor shortages, instability in global economic conditions and geopolitical matters, as well as volatility in financial markets; (x) uncertainty in U.S. fiscal and monetary policy, including the interest rate policies of the Federal Reserve; (xi) the credit risks of lending activities, which may be affected by deterioration in real estate markets and the financial condition of borrowers, and the operational risk of lending activities, including the effectiveness of OceanFirst’s and Flushing’s underwriting practices and the risk of fraud; (xii) fluctuations in the demand for loans; (xiii) the ability to develop and maintain a strong core deposit base or other low cost funding sources necessary to fund OceanFirst’s and Flushing’s activities particularly in a rising or high interest rate environment; (xiv) the rapid withdrawal of a significant amount of deposits over a short period of time; (xv) results of examinations by regulatory authorities of OceanFirst or Flushing and the possibility that any such regulatory authority may, among other things, limit OceanFirst’s or Flushing’s business activities, restrict OceanFirst’s or Flushing’s ability to invest in certain assets, refrain from issuing an approval or non-objection to certain capital or other actions, increase OceanFirst’s or Flushing’s allowance for credit losses, result in write-downs of asset values, restrict OceanFirst’s or Flushing’s ability or that of OceanFirst’s or Flushing’s bank subsidiary to pay dividends, or impose fines, penalties or sanctions; (xvi) the impact of bank failures or other adverse developments at other banks on general investor sentiment regarding the stability and liquidity of banks; (xvii) changes in the markets in which OceanFirst and Flushing compete, including with respect to the competitive landscape, technology evolution or regulatory changes; (xviii) changes in consumer spending, borrowing and saving habits; (xix) slowdowns in securities trading or shifting demand for security trading products; (xx) the impact of pandemics and other catastrophic events or disasters on the global economy and financial market conditions and our business, results of operations, and financial condition; (xxi) legislative or regulatory changes; (xxii) changes in U.S. trade policies, including the imposition of tariffs and retaliatory tariffs, (xxiii) impact of operating in a highly competitive industry; (xxiv) reliance on third party service providers; (xxv) competition in retaining key employees; (xxvi) risks related to data security and privacy, including the impact of any data security breaches, cyberattacks, employee or other internal misconduct, malware, phishing or ransomware, physical security breaches, natural disasters, or similar disruptions; (xxvii) changes to accounting principles and guidelines; (xxviii) potential litigation relating to the proposed transaction that could be instituted against OceanFirst, Flushing or their respective directors and officers, including the effects of any outcomes related thereto; (xxix) volatility in the trading price of OceanFirst’s or Flushing’s securities; (xxx) the ability to implement business plans, forecasts, and other expectations after the completion of the proposed transaction, and identify and realize additional opportunities; (xxxi) the possibility that the transaction may be more expensive to complete than anticipated, including as a result of unexpected expenses, factors or events; (xxxii) the possibility that the anticipated benefits of the transaction are not realized when expected or at all, including as a result of the impact of, or problems arising from, the integration of the two companies or as a result of the strength of the economy and competitive factors in the areas where OceanFirst and Flushing do business; and (xxxiii) the dilution caused by OceanFirst’s issuance of additional shares of its capital stock in connection with the transaction. The foregoing list of factors is not exhaustive. All forward-looking statements are expressly qualified in their entirety by the cautionary statements set forth above.

You should carefully consider the foregoing factors and the other risks and uncertainties described in the “Risk Factors” section of OceanFirst’s registration statement on Form S-4 that contains a joint proxy statement/prospectus and other documents filed by OceanFirst or Flushing from time to time with the U.S. Securities and Exchange Commission. These filings do and will identify and address other important risks and uncertainties that could cause actual events and results to differ materially from those contained in the forward-looking statements. If any of these risks materialize or our assumptions prove incorrect, actual events and results could differ materially from those contained in the forward-looking statements. There may be additional risks that neither OceanFirst nor Flushing presently knows or that OceanFirst or Flushing currently believes are immaterial that could also cause actual events and results to differ from those contained in the forward-looking statements. In addition, forward-looking statements reflect OceanFirst’s and Flushing’s expectations, plans or forecasts of future events and views as of the date of this Current Report on Form 8-K. OceanFirst and Flushing anticipate that subsequent events and developments will cause OceanFirst’s and Flushing’s assessments to change. While OceanFirst and Flushing may elect to update these forward-looking statements at some point in the future, OceanFirst and Flushing specifically disclaim any obligation to do so, unless required by applicable law. These forward-looking statements should not be relied upon as representing OceanFirst’s and Flushing’s assessments as of any date subsequent to the date of this Current Report on Form 8-K. Accordingly, undue reliance should not be placed upon the forward-looking statements. Forward-looking statements speak only as of the date they are made. Neither OceanFirst nor Flushing gives any assurance that either OceanFirst or Flushing, or the combined company, will achieve the results or other matters set forth in the forward-looking statements.
