Forward Looking Statements This presentation contains certain statements that may be considered forward-looking statements under the Private Securities Litigation Reform Act of 1995 and other federal securities laws, including certain plans, exceptions, goals, projections, and statements, which are subject to numerous risks, assumptions, and uncertainties. Forward-looking statements can be identified by the use of the words “believe,” “expect,” “anticipate,” “intend,” “estimate,” “assume,” “plan,” “target,” or “goal” or future or conditional verbs such as “will,” “may,” “might,” “should,” “could” and other expressions which predict or indicate future events or trends and which do not relate to historical matters. Forward-looking statements should not be relied on, because they involve known and unknown risks, uncertainties and other factors, some of which are beyond the control of Camden National Corporation (the “Company”). These risks, uncertainties and other factors may cause the actual results, performance or achievements of the Company to be materially different from the anticipated future results, performance or achievements expressed or implied by the forward-looking statements. The following factors, among others, could cause the Company’s financial performance to differ materially from the Company’s goals, plans, objectives, intentions, expectations and other forward-looking statements: weakness in the United States economy in general and the regional and local economies within the New England region and Maine, which could result in a deterioration of credit quality, an increase in the allowance for loan losses or a reduced demand for the Company’s credit or fee-based products and services; changes in trade, monetary, and fiscal policies and laws, including interest rate policies of the Board of Governors of the Federal Reserve System; inflation, interest rate, market, and monetary fluctuations; competitive pressures, including continued industry consolidation and the increased financial services provided by non-banks; volatility in the securities markets that could adversely affect the value or credit quality of the Company’s assets, impairment of goodwill, the availability and terms of funding necessary to meet the Company’s liquidity needs, and could lead to impairment in the value of securities in the Company's investment portfolio; changes in information technology that require increased capital spending; changes in consumer spending and savings habits; changes in tax, banking, securities and insurance laws and regulations; and changes in accounting policies, practices and standards, as may be adopted by the regulatory agencies as well as the Financial Accounting Standards Board ("FASB"), and other accounting standard setters. You should carefully review all of these factors, and be aware that there may be other factors that could cause differences, including the risk factors listed in the Company’s filings with the SEC, including our Annual Report on Form 10-K for the year ended December 31, 2017, as updated by the Company's quarterly reports on Form 10-Q and other filings with the Securities and Exchange Commission. You should carefully review the risk factors described therein and should not place undue reliance on our forward-looking statements. These forward-looking statements were based on information, plans and estimates at the date of this report, and we undertake no obligation to update any forward-looking statements to reflect changes in underlying assumptions or factors, new information, future events or other changes, except to the extent required by applicable law or regulation. 1
