CORPORATION (NASDAQ: FBAN) WWW.FNBCORPORATION.COM NAPLES, FL 34102 FOR IMMEDIATE RELEASE DATE: July 17, 2001 CONTACT: Clay W. Cone Vice President-Corporate Affairs 941-436-1676 F.N.B. CORPORATION REPORTS 23 PERCENT INCREASE IN SECOND QUARTER OPERATING INCOME NAPLES, FL, July 17 - F.N.B. Corporation (Nasdaq: FBAN) today reported second quarter 2001 core operating earnings of $13.2 million, or $0.50 per diluted share. This represents an increase of 23% when compared to the $10.7 million, or $0.41 per diluted share, in core operating earnings reported for the second quarter of last year. These results were in line with analysts' consensus estimates and company targets. F.N.B.'s second quarter 2001 core operating results, which exclude merger-related and other nonrecurring charges, represent a return on average assets (ROA) of 1.3% and a return on average equity (ROE) of 15.2%. The company's second quarter operating revenue totaled $63.2 million (FTE), an increase of 13% over the second quarter of last year. For the first six months of 2001, the company reported core operating earnings of $24.2 million, or $0.92 per diluted share, up 13% when compared to the $21.4 million, or $0.82 per diluted share, in core operating earnings reported for the same period a year earlier. "F.N.B. continues to enjoy solid revenue and income growth while maintaining a keen eye on credit quality," said Gary L. Tice, President and Chief Executive Officer of F.N.B. Corporation. "The company is also achieving success in its efforts to boost fee income, which grew to a third of total revenues during the second quarter of this year." Including one-time, merger-related and other nonrecurring expenses, net income for the second quarter was $11.0 million, or 0.41 per diluted share. For the first six months of 2001, net income was more than $17.2 million, or $0.65 per diluted share. "These latest results are consistent with those discussed in prior releases and keep F.N.B. Corporation on track with its previously disclosed estimates of $0.51 per share core 3 operating earnings in the third quarter of 2001 and $0.55 per share in the fourth quarter of 2001," Tice said. "This sets the stage for what we anticipate will be another record year." During the second quarter, F.N.B. completed the affiliation of Citizens Community Bancorp Inc., the parent of Citizens Community Bank of Florida. Based on Marco Island, Florida, Citizens Community Bank had $150 million in deposits and four branch offices. With the completion of this merger, F.N.B. is now the second-largest financial institution in the Naples/Collier County area with 11 offices and more than $725 million in deposits. Also during the quarter, F.N.B. completed the relocation of its principal executive offices. The company has reincorporated in the state of Florida and now legally operates from its corporate headquarters located in Naples, Florida. The relocation plan originally was announced in March and was approved by shareholders at the Annual Meeting in April. The company also began to realize the cost savings related to its charter consolidation plan, which was implemented during the first quarter of 2001. Under the program, each of F.N.B.'s community bank affiliates was combined under a single operating charter for each state. This plan has resulted in significant savings by eliminating operational redundancies. "The consolidation program improved the efficiency of our operations in Pennsylvania and Florida, producing after-tax benefits of approximately $2.9 million," Tice said. "It should also be noted that all this was accomplished without disruption to our valued customers." On June 14, 2001, F.N.B. Corporation and Promistar Financial Corporation announced the signing of a definitive agreement in which Promistar will merge with and into F.N.B. Promistar, headquartered in Johnstown, Pennsylvania, is a bank holding company with total assets of more than $2.3 billion and 82 offices in southwestern Pennsylvania. Due diligence on the transaction has been completed by both parties and completion of the transaction is subject to the normal regulatory approvals as well as the approval of F.N.B. and Promistar shareholders. The transaction is scheduled for completion in the first quarter of 2002 and is expected to be accounted for as a pooling of interests. "We have been actively meeting with Promistar management and employees and are making considerable progress in combining these two fine organizations," Tice said. "This merger will be very beneficial to the shareholders and customers of both F.N.B. and Promistar." For the second quarter of 2001, noninterest income, which includes earnings from trust, investment management services and other sources of fee income, was $20.1 million. 4 This was an increase of 38% over the same period a year earlier. For the first half of 2001, noninterest income was $38.7 million, up 32% from the first six months of 2000. "We are particularly pleased with the results of our ongoing initiative to boost fee income," Tice said. "By doing so, the company will significantly reduce its dependance on net interest income and produce a much more predictable revenue stream in the future." Net interest income on a tax equivalent basis was $43.1 million in the second quarter of 2001, a 4% increase from the $41.3 million in the second quarter of 2000. The net interest margin was 4.63% in the second quarter of 2001 compared to 4.67% in the second quarter of 2000. The net interest margin was improved from 4.50% in the first quarter of 2001. Noninterest expense for the quarter, excluding merger-related and other nonrecurring charges, was $40.2 million, up 10% from the $36.6 million in the second quarter of 2000. For the first half of 2001, noninterest expense, excluding merger-related and other nonrecurring charges, was $80.7 million, up 11% from the first six months of 2000. The increase in noninterest expense reflects the company's expansion into insurance, wealth management and other fee-based lines of business during the second half of 2000. The company continues to maintain excellent asset quality. As of June 30, 2001, the allowance for loan losses as a percentage of total loans was 1.30%, compared to 1.28% a year earlier. Non-performing assets represented 0.42% of total loans, compared with 0.43% in the second quarter of last year. For the second quarter of 2001, net charge-offs were 0.41% of average loans, compared to 0.28% for the same period a year earlier. Book value per common share increased 10%, from $12.42 per share at the end of the second quarter of 2000 to $13.62 per share at the end of the second quarter of 2001. Shareholders' equity also grew 10% to $353 million compared to $322 million a year ago. F.N.B. Corporation is a $4.1 billion diversified financial services company headquartered in Naples, Florida.
