Two Banks.

GROWING STRONGER TO SERVE YOU BETTER

One Partnership.


LOGO

In June 2011, Parkvale Financial Corporation, the holding company of Parkvale Savings Bank, announced the intent to merge with F.N.B. Corporation, the holding company of First National Bank of Pennsylvania, based in Hermitage, PA. Upon completion of the merger, Parkvale’s name will change to First National Bank of Pennsylvania, but the same friendly service you have come to expect will remain.

Here’s What You Can Expect.

Parkvale Savings Bank will become part of the fourth largest Pennsylvania-based banking institution with approximately $11.6 billion in combined assets post merger. The merger fits well with the commitment of both banks to serve the banking needs of residents and businesses of our communities in Pennsylvania, Eastern Ohio and West Virginia. Both banks have a genuine concern for their customers and their communities.

Although the name and logo will change, you should experience no service interruptions throughout the merger process. In fact, you can expect business-as- usual. The goal is to complete the transition seamlessly while providing you with even more product and service choices, including expanded wealth management, insurance and investment offerings and enhanced Business Banking Solutions, to name a few.

You will also be delighted to know that Parkvale employees, who have worked so hard to make your banking experience and your bank one of the best in the region, will continue to serve you like before.

You can expect consistent, up-to-date communications from both banks regarding your accounts. If you have any questions regarding an account, please contact your local office.
