F.N.B. Corporation is a financial services corporation based in Pittsburgh, Pennsylvania, and the holding company for its largest subsidiary, First National Bank. As of October 19, 2017, FNB has total assets of $31 billion. There are more than 400 First National Bank offices in Pennsylvania, Ohio, Maryland, West Virginia, North Carolina and South Carolina. The company has more than 4,800 employees.

First National Bank was founded in Mercer County, Pennsylvania in 1864 under the name The First National Bank of West Greenville and operated out of the house of then Bank President, Samuel P. Johnston, in Greenville, Pennsylvania.

The bank remained a fixture in Mercer County through World War I, the Great Depression and World War II. In 1946, bank assets totaled approximately $2 million and the bank was still housed in one office.

Across the next three decades, the bank continued to grow, and in 1974, F.N.B. Corporation was established as a financial services holding company for a growing family of business entities which included the bank, under then name The First National Bank of Mercer County and with an asset size of $120 million, and Regency Finance Company.

Along with completing the acquisition of ten branch offices from First National Bank of Pennsylvania in July 1992, First National Bank of Mercer County acquired the name and formally changed its name to the current First National Bank of Pennsylvania. Around this time, the First National Bank of Western Pennsylvania in nearby New Castle changed its name to First Western Bank to avoid confusion; that bank is now part of Huntington Bancshares after several other mergers.

As of 2003, the company had grown to assets of $4.6 billion with more than 125 banking offices and began trading common shares on the New York Stock Exchange under the ticker symbol “FNB.” Today, it is included in Standard & Poor’s MidCap 400 Index with the Global Industry Classification Standard (GICS) Regional Banks Sub-Industry Index.

Current Chief Executive Officer Vincent J. Delie, Jr., joined the bank in 2005 as President of the Pittsburgh Region. Since then, the company has shown tremendous growth, both organically and through a series of major mergers.

In 2012, FNB acquired Parkvale Savings Bank, which was based in Monroeville.

Today, FNB is the second largest bank based in Pennsylvania measured by assets. The company has locations in metropolitan markets including: Pittsburgh, Pennsylvania; Baltimore, Maryland; Cleveland, Ohio; and Charlotte, Raleigh, Durham and the Piedmont Triad (Winston-Salem, Greensboro and High Point) in North Carolina.

In 2016, FNB agreed to a $1.4 billion deal with Yadkin Financial of Raleigh, North Carolina, the largest deal in the company's history, giving FNB 98 branches in North Carolina. The merger was completed on March 11, 2017.

In May 2017, FNB announced its regional headquarters would locate in a 22-story building in Raleigh to be called FNB Tower, with groundbreaking set for December 2017 and completion in 2019.

In July 2014, FNB announced that Pittsburgh had officially been named the corporation’s headquarters. FNB’s growth in Pittsburgh has expanded from a single banking office in 1997 to more than 100 locations and a top three retail deposit market share today. Over the course of the last 10 years, FNB has continued to expand its Pittsburgh campus to include executive offices, commercial banking, capital markets, private banking, commercial real estate lending, mortgage banking, marketing and more. FNB is the second-largest bank holding company based in Pittsburgh, measured by total assets.

Vincent J. Delie, Jr., is President and CEO of F.N.B. Corporation and First National Bank. He joined F.N.B. in 2005 as head of the Pittsburgh Region. In 2011, Delie became President of F.N.B. Corporation and in 2012 he was additionally named Chief Executive Officer and elected to the Board of Directors. Delie reassumed his role as President of First National Bank when John Williams retired from the position in 2015.
