Forward Looking Statements
This presentation contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. These forward-looking statements include, but are not limited to, statements about (i) the benefits of the merger between Provident Financial Services (“Provident” or “PFS”) and First Sentinel Bancorp, Inc. (“First Sentinel” or “FSLA”), including future financial and operating results, cost savings and accretion to reported earnings that may be realized from the merger; (ii) Provident’s and First Sentinel’s plans, objectives, expectations and intentions and other statements contained in this presentation that are not historical facts; and (iii) other statements identified by words such as “expects,” “anticipates,” “intends,” “plans,” “believes,” “seeks,” “estimates” or words of similar meaning. These forward-looking statements are based upon the current beliefs and expectations of Provident’s and First Sentinel’s management and are inherently subject to significant business, economic and competitive uncertainties and contingencies, many of which are beyond our control. In addition, these forward-looking statements are subject to assumptions with respect to future business strategies and decisions that are subject to change. Actual results may differ materially from the anticipated results discussed in these forward-looking statements.
The following factors, among others, could cause actual results to differ materially from the anticipated results or other expectations expressed in the forward-looking statements: (1) the businesses of Provident and First Sentinel may not be combined successfully, or such combination may take longer to accomplish than expected; (2) the cost savings from the merger may not be fully realized or may take longer to realize than expected; (3) operating costs, customer loss and business disruption following the merger, including adverse effects on relationships with employees, may be greater than expected; (4) governmental approvals of the merger may not be obtained, or adverse regulatory conditions may be imposed in connection with governmental approvals of the merger; (5) the stockholders of First Sentinel or Provident may fail to approve the merger; (6) adverse governmental or regulatory policies may be enacted; (7) the interest rate environment may further compress margins and adversely affect net interest income; (8) the risks associated with continued diversification of assets and adverse changes to credit quality; (9) difficulties associated with achieving expected future financial results; (10) competition from other financial services companies in Provident’s and First Sentinel’s markets; (11) the risk of an economic slowdown that would adversely affect credit quality and loan originations. Additional factors that could cause actual results to differ materially from those expressed in the forward-looking statements are discussed in Provident’s and First Sentinel’s reports (such as Annual Reports on Form 10-K, Quarterly Reports on Form 10-Q and Current Reports on Form 8-K) filed with the Securities and Exchange Commission and available at the SEC’s Internet site (http://www.sec.gov). All subsequent written and oral forward-looking statements concerning the proposed transaction or other matters attributable to Provident or First Sentinel or any person acting on their behalf are expressly qualified in their entirety by the cautionary statements above. Except as required by law, Provident and First Sentinel do not undertake any obligation to update any forward-looking statement to reflect circumstances or events that occur after the date the forward-looking statement is made.
