| 2 Disclaimer & Forward Looking FORWARD-LOOKING STATEMENTS This communication includes “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995, Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended, with respect to the beliefs, goals, intentions, and expectations of PFIS and FNCB regarding the proposed transaction, revenues, earnings, earnings per share, loan production, asset quality, and capital levels, among other matters; our estimates of future costs and benefits of the actions we may take; our assessments of expected losses on loans; our assessments of interest rate and other market risks; our ability to achieve our financial and other strategic goals; the expected timing of completion of the proposed transaction; the expected cost savings, synergies, returns and other anticipated benefits from the proposed transaction; and other statements that are not historical facts. Forward‐looking statements are typically identified by such words as “believe,” “expect,” “anticipate,” “intend,” “outlook,” “estimate,” “forecast,” “project,” “will,” “should,” and other similar words and expressions, and are subject to numerous assumptions, risks, and uncertainties, which change over time. These forward-looking statements include, without limitation, those relating to the terms, timing and closing of the proposed transaction. Additionally, forward‐looking statements speak only as of the date they are made; and except as required by law, PFIS and FNCB do not assume any duty, and do not undertake, to update such forward‐looking statements, whether written or oral, that may be made from time to time, whether as a result of new information, future events, or otherwise. Furthermore, because forward‐looking statements are subject to assumptions and uncertainties, actual results or future events could differ, possibly materially, from those indicated or implied in such forward-looking statements as a result of a variety of factors, many of which are beyond the control of PFIS and FNCB. Such statements are based upon the current beliefs and expectations of the management of PFIS and FNCB and are subject to significant risks and uncertainties outside of the control of the parties. Caution should be exercised against placing undue reliance on forward-looking statements. The factors that could cause actual results to differ materially include the following: the occurrence of any event, change or other circumstances that could give rise to the right of one or both of the parties to terminate the definitive merger agreement between PFIS and FNCB; the outcome of any legal proceedings that may be instituted against PFIS or FNCB; the possibility that the proposed transaction will not close when expected or at all because required regulatory, shareholder or other approvals are not received or other conditions to the closing are not satisfied on a timely basis or at all, or are obtained subject to conditions that are not anticipated (and the risk that required regulatory approvals may result in the imposition of conditions that could adversely affect the surviving corporation or the expected benefits of the proposed transaction); the ability of PFIS and FNCB to meet expectations regarding the timing, completion and accounting and tax treatments of the proposed transaction; the risks related to capital actions of PFIS, FNCB and the combined entity, including related to actions concerning dividends; the risk that any announcements relating to the proposed transaction could have adverse effects on the market price of the common stock of either or both parties to the proposed transaction; the possibility that the anticipated benefits of the proposed transaction will not be realized when expected or at all, including as a result of the impact of, or problems arising from, the integration of the two companies or as a result of the strength of the economy and competitive factors in the areas where PFIS and FNCB do business; the risks related to PFIS and FNCB not achieving their estimated financial performance; the risks related to changes in the interest rate environment, including the recent increases in the Board of Governors of the Federal Reserve System benchmark rate and duration at which such increased interest rate levels are maintained, which could adversely affect PFIS’ and FNCB’s revenue and expenses, the value of assets and obligations, and the availability and cost of capital and liquidity; risks related to the uncertainty in U.S. fiscal and monetary policy, including the interest rate policies of the Board of Governors of the Federal Reserve System; risks related to the volatility and disruptions in global capital and credit markets; risks related to the movements in interest rates; risks related to reform of LIBOR, the credit risks of lending activities, which may be affected by deterioration in real estate markets and the financial condition of borrowers, and the operational risk of lending activities, including the effectiveness of PFIS’ and FNCB’s underwriting practices and the risk of fraud; risks related to the fluctuations in the demand for loans; risk related to the ability to develop and maintain a strong core deposit base or other low cost funding sources necessary to fund PFIS’ and FNCB’s activities particularly in a rising or high interest rate environment; risks related to the rapid withdrawal of a significant amount of deposits over a short period of time; the risk related to the impact of other bank failures or other adverse developments at other banks on general investor sentiment regarding the stability and liquidity of banks; risks related to the impact of natural disasters or health epidemics; risks related to data security and privacy, including the impact of any data security breaches, cyberattacks, employee or other internal misconduct, malware, phishing or ransomware, physical security breaches, natural disasters, or similar disruptions; risks related to volatility in the trading price of PFIS’ and FNCB’s common stock; certain restrictions during the pendency of the proposed transaction that may impact the parties’ ability to pursue certain business opportunities or strategic transactions; the possibility that the transaction may be more expensive to complete than anticipated, including as a result of unexpected factors or events; diversion of management’s attention from ongoing business operations and opportunities; the possibility that the parties may be unable to achieve expected synergies and operating efficiencies in the merger within the expected timeframes or at all and to successfully integrate FNCB's operations and those of PFIS; such integration may be more difficult, time-consuming or costly than expected; revenues following the proposed transaction may be lower than expected; PFIS and FNCB's success in executing their respective business plans and strategies and managing the risks involved in the foregoing; the dilution caused by PFIS issuance of additional shares of its capital stock in connection with the proposed transaction; effects of the announcement, pendency or completion of the proposed transaction on the ability of PFIS and FNCB to retain customers and retain and hire key personnel and maintain relationships with their suppliers, and on their operating results and businesses generally;
