Cautionary Statement Regarding Forward-Looking Information
and Non-GAAP Financial Information
2
This presentation and the reports F.N.B. Corporation files with the Securities and Exchange Commission often contain “forward-looking 
statements” relating to present or future trends or factors affecting the banking industry and, specifically, the financial operations, markets and
products of F.N.B. Corporation. These forward-looking statements involve certain risks and uncertainties. There are a number of important factors
that could cause F.N.B. Corporation’s future results to differ materially from historical performance or projected performance. These factors 
include, but are not limited to: (1) a significant increase in competitive pressures among financial institutions; (2) changes in the interest rate
environment that may reduce interest margins; (3) changes in prepayment speeds, loan sale volumes, charge-offs and loan loss provisions; (4)
general economic conditions; (5) various monetary and fiscal policies and regulations of the U.S. government that may adversely affect the
businesses in which F.N.B. Corporation is engaged; (6) technological issues which may adversely affect F.N.B. Corporation’s financial operations
or customers; (7) changes in the securities markets; (8) risk factors mentioned in the reports and registration statements F.N.B. Corporation files
with the Securities and Exchange Commission; (9) housing prices; (10) job market; (11) consumer confidence and spending habits; (12) estimates
of fair value of certain F.N.B. Corporation assets and liabilities; (13) transaction risks associated with the pending merger of BCSB Bancorp, Inc.,
and integration challenges related to the recently completed mergers with PVF Capital Corp. and Annapolis Bancorp, Inc. and the difficulties
encountered in expanding into a new market and (14) the effects of current, pending and future legislation, regulation and regulatory actions. 
F.N.B. Corporation undertakes no obligation to revise these forward-looking statements or to reflect events or circumstances after the date of this
presentation.
To supplement its consolidated financial statements presented in accordance with Generally Accepted Accounting Principles (GAAP), the
Corporation provides additional measures of operating results, net income and earnings per share (EPS) adjusted to exclude certain costs,
expenses, and gains and losses.  The Corporation believes that these non-GAAP financial measures are appropriate to enhance the
understanding of its past performance as well as prospects for its future performance.  In the event of such a disclosure or release, the Securities
and Exchange Commission’s Regulation G requires: (i) the presentation of the most directly comparable financial measure calculated and
presented in accordance with GAAP and (ii) a reconciliation of the differences between the non-GAAP financial measure presented and the most
directly comparable financial measure calculated and presented in accordance with GAAP. 
The Appendix to this presentation contains non-GAAP financial measures used by the Corporation to provide information useful to investors in
understanding the Corporation's operating performance and trends, and facilitate comparisons with the performance of the Corporation's peers. 
While the Corporation believes that these non-GAAP financial measures are useful in evaluating the Corporation, the information should be
considered supplemental in nature and not as a substitute for or superior to the relevant financial information prepared in accordance with GAAP. 
The non-GAAP financial measures used by the Corporation may differ from the non-GAAP financial measures other financial institutions use to
measure their results of operations.  This information should be reviewed in conjunction with the Corporation’s financial results disclosed on
October 17, 2013 and in its periodic filings with the Securities and Exchange Commission.
