Exhibit 99.1

June 2, 2016

To the Shareholders of Foundation Bancorp, Inc.

Dear Fellow Shareholder:

On April 26, 2016, Foundation Bancorp, Inc. (“Foundation”) and Pacific Continental Corporation (“Pacific Continental”) announced the signing of a merger agreement pursuant to which Foundation shall be merged with and into Pacific Continental subject to the terms and conditions set forth in the agreement. Pacific Continental is a bank holding company headquartered in Eugene, Oregon. As of March 31, 2016, Pacific Continental had approximately $1.97 billion in total assets, $1.70 billion in total deposits and approximately $1.41 billion in net loans.

On a pro forma combined basis, the combined company would have total assets of $2.4 billion, total loans outstanding of $1.7 billion and total deposits of $2.1 billion as of March 31, 2016 (unaudited), including $443.8 million in loans and $561.9 million in deposits in the Seattle metropolitan area.

The proposed merger with Pacific Continental offers the ability to enhance shareholder value for Foundation shareholders, and provides significant opportunities to continue to expand and diversify the respective customer bases of Foundation and Pacific Continental. As Pacific Continental’s common shares are traded on NASDAQ, its shares are a much more liquid asset for investors.

The headquarters for Pacific Continental will remain in Eugene, Oregon. Subject to regulatory approval, it is expected that Pacific Continental’s existing branch in Bellevue, Washington will be consolidated into Foundation’s branch. Two representatives from Foundation, Thomas Ellison and Duane Woods, will be appointed to the board of directors of Pacific Continental following the merger. Roger S. Busse will continue to serve as President and Chief Executive Officer of Pacific Continental.

We are very excited about the opportunities that this merger will bring to our company, our shareholders and our customers. We enclose with this letter a copy of the press release that was issued when the merger was announced. We are confident you will find the merger highlights outlined in the press release impressive.

In due course you will receive a detailed prospectus and proxy statement that will set forth complete information concerning the transaction. It is very important that you carefully review the prospectus and proxy statement in full before you decide how to vote on the merger.

Thank you for your continued loyalty and support.
