We are pleased to share that earlier today we announced that Bryn Mawr Bank Corporation has agreed to combine with WSFS Financial to create the premier, locally headquartered bank and wealth management franchise in the Greater Philadelphia and Delaware region.

WSFS Bank, founded in 1832 and headquartered in Wilmington, Delaware, is the oldest and largest bank and trust company headquartered in the Greater Philadelphia and Delaware region; WSFS is one of the ten oldest banks in the United States continuously operating under the same name.

This combination will provide you with more locations and access to one of the region’s largest ATM networks. Bryn Mawr Trust will be the prominent brand in our combined wealth premier division. Together, we will strengthen our efforts as we serve our neighbors and friends, continuing to provide the highest levels of support and service you expect.

The closing of the combination of our two organizations is projected for early in the fourth quarter, 2021. Until then, we will continue to operate separately as BMT and WSFS, with the same products, services, and solutions.

At this time, no action is required on your part. Please continue to use your current BMT locations and resources, and visit bmt.com for the most up-to-date information on this historic partnership. In the meantime, should you have any questions, please call our Customer Care Center at 610.525.1700.

Thank you for trusting us with your banking needs. We appreciate your business and look forward to providing you timely updates on our progress as we combine our organizations and build the best bank for our region and you.

Sincerely,

Frank Leto

President, CEO and Director

Bryn Mawr Bank Corp.

Forward-Looking Statements

This communication contains estimates, predictions, opinions, projections and other “forward-looking statements” as that phrase is defined in the Private Securities Litigation Reform Act of 1995. Forward-looking statements include, without limitation, statements relating to the impact WSFS and Bryn Mawr expect their proposed merger to have on the combined entity’s operations, financial condition, and financial results, and WSFS’s and Bryn Mawr’s expectations about their ability to successfully integrate their respective businesses and the amount of cost savings and overall operational efficiencies WSFS and Bryn Mawr expect to realize as a result of the proposed acquisition. The forward-looking statements also include predications or expectations of future business or financial performance as well as goals and objectives for future operations, financial and business trends, business prospects, and management’s outlook or expectations for earnings, revenues, expenses, capital levels, liquidity levels, asset quality or other future financial or business performance, strategies or expectations. The words “believe,” “intend,” “expect,” “anticipate,” “strategy,” “plan,” “estimate,” “approximately,” “target,” “project,” “propose,” “possible,” “potential,” “should” and similar expressions, among others, generally identify forward-looking statements. Such forward-looking statements are based on various assumptions (many of which are beyond the control of WSFS and Bryn Mawr) and are subject to risks and uncertainties (which change over time) and other factors which could cause actual results to differ materially from those currently anticipated. Such risks and uncertainties include, but are not limited to, the possibility that the proposed acquisition does not close when expected or at all because required regulatory, stockholder or other approvals and other conditions to closing are not received or satisfied on a timely basis or at all; the delay in or failure to close for any other reason; changes in WSFS’s share price before closing; the outcome of any legal proceedings that may be instituted against WSFS or Bryn Mawr; the occurrence of any event, change or other circumstance that could give rise to the right of one or both parties to terminate the merger agreement providing for the merger; the risk that the businesses of WSFS and Bryn Mawr will not be integrated successfully; the possibility that the cost savings and any synergies or other anticipated benefits from the proposed acquisition may not be fully realized or may take longer to realize than expected; disruption from the proposed acquisition making it more difficult to maintain relationships with employees, customers or other parties with whom WSFS or Bryn Mawr have business relationships; diversion of management time on merger-related issues; risks relating to the potential dilutive effect of the shares of WSFS common stock to be issued in the proposed transaction; the reaction to the proposed transaction of the companies’ customers, employees and counterparties; uncertainty as to the extent of the duration, scope, and impacts of the COVID-19 pandemic on WSFS, Bryn Mawr and the proposed transaction; and other factors, many of which are beyond the control of WSFS and Bryn Mawr. We refer you to the “Risk Factors” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” sections of WSFS’s Annual Report on Form 10-K for the year ended December 31, 2020, Bryn Mawr’s Annual Report on Form 10-K for the year ended December 31, 2020 and any updates to those risk factors set forth in WSFS’s and Bryn Mawr’s Quarterly Reports on Form 10-Q, Current Reports on Form 8-K and other filings, which have been filed by WSFS and Bryn Mawr with the SEC and are available on the SEC’s website at www.sec.gov.
