OceanFirst Financial Corp. Announces Agreements to Acquire Two River Bancorp & Country Bank Holding Company, Inc. August 9, 2019 Exhibit 99.1

Forward Looking Statements Investor Presentation This communication contains “forward-looking statements” within the meaning of the federal securities laws, including Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. These forward-looking statements may include: management plans relating to either the proposed transaction with Two River Bancorp (“Two River” or “TRCB”, and such transaction the “Two River Transaction”) or the proposed transaction with Country Bank Holding Company, Inc. (“Country Bank” or “CYHC”, and such transaction the “Country Bank Transaction”); the expected timing of the completion of either the Two River Transaction or Country Bank Transaction or both such transactions; the ability to complete either the Two River Transaction or Country Bank Transaction or both such transactions; the ability to obtain any required regulatory, stockholder or other approvals; any statements of the plans and objectives of management for future operations, products or services, including the execution of integration plans relating to either the Two River Transaction or Country Bank Transaction or both such transactions; any statements of expectation or belief; projections related to certain financial metrics; and any statements of assumptions underlying any of the foregoing. Forward-looking statements are typically identified by words such as “believe,” “expect,” “anticipate,” “intend,” “seek”, “plan”, “will”, “would”, “target,” “outlook,” “estimate,” “forecast,” “project” and other similar words and expressions or negatives of these words. Forward-looking statements are subject to numerous assumptions, risks and uncertainties, which change over time and are beyond our control. Forward-looking statements speak only as of the date they are made. Neither OceanFirst nor Two River nor Country Bank assumes any duty and does not undertake to update any forward-looking statements. Because forward-looking statements are by their nature, to different degrees, uncertain and subject to assumptions, actual results or future events could differ, possibly materially, from those that OceanFirst, Two River or Country Bank anticipated in its forward-looking statements, and future results could differ materially from historical performance. Factors that could cause or contribute to such differences include, but are not limited to, those included under Item 1A “Risk Factors” in OceanFirst’s Annual Report on Form 10-K, those included under Item 1A “Risk Factors” in Two River’s Annual Report on Form 10-K and those disclosed in OceanFirst’s and Two River’s other periodic reports filed with the Securities and Exchange Commission (the “SEC”), as well as the possibility that expected benefits of either the Two River Transaction or Country Bank Transaction or both such transactions and the recently completed acquisition of Capital Bank of New Jersey by OceanFirst (the “Recent Acquisition”) may not materialize in the timeframe expected or at all, or may be more costly to achieve; that either the Two River Transaction or Country Bank Transaction or both such transactions may not be timely completed, if at all; that prior to the completion of either of Two River Transaction or Country Bank Transaction or both such transactions or thereafter, OceanFirst’s, Two River’s and Country Bank’s respective businesses may not perform as expected due to transaction-related uncertainty or other factors; that the parties are unable to successfully implement integration strategies related to either the Two River Transaction or Country Bank Transaction or both such transactions or the Recent Acquisition; that, with respect to either the Two River Transaction or Country Bank Transaction or both such transactions, required regulatory, stockholder or other approvals are not obtained or other customary closing conditions are not satisfied in a timely manner or at all; reputational risks and the reaction of the companies’ stockholders, customers, employees and other constituents to the Two River Transaction or Country Bank Transaction or both such transactions, and diversion of management time as a result of the matters related to either the Two River Transaction or Country Bank Transaction or both such transactions. As they relate to the Two River Transaction, these risks, as well as other risks associated with both proposed transactions, will be more fully discussed in the prospectus of OceanFirst and proxy statement of Two River. As they relate to the Country Bank Transaction, these risks, as well as other risks associated with both proposed transactions, will be more fully discussed in the prospectus of OceanFirst and proxy statement of Country Bank. These prospectuses, proxy statements and risk factors will be included in the registration statements on each Form S-4 that will be filed with the SEC in connection with each of the proposed transactions. The list of factors presented here, and the list of factors that will be presented in the registration statements on Form S-4, is not, and should not be considered, a complete statement of all potential risks and uncertainties. Unlisted factors may present significant additional obstacles to the realization of forward looking statements. For any forward-looking statements made in this communication or in any documents, OceanFirst, Two River and Country Bank claim the protection of the safe harbor for forward-looking statements contained in the Private Securities Litigation Reform Act of 1995. Annualized, pro forma, projected and estimated numbers are used for illustrative purposes only, are not forecasts and may not reflect actual results.
