12 Forward-Looking Statements and Additional Information This presentation may contain “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995, as amended, including certain plans, expectations, 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,” “potential,” 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 inherent risks and uncertainties, some of which are beyond the control of Camden National Corporation (the “Company”), that could cause actual results to differ materially from what is reflected in the forward-looking statements. These risks and uncertainties include: weakness in the United States economy in general and the regional and local economies within the Northern New England region, which could result in a deterioration of credit quality, an increase in the allowance for credit 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 Federal Reserve interest rate policies or the imposition of tariffs or retaliatory tariffs and related litigation; inflation, interest rate, market, and monetary fluctuations; competitive pressures, including continued industry consolidation and the increased financial services provided by non-banks; deterioration in the value of the Company's investment securities; commercial real estate vacancies and their impact on the ability of borrowers to repay their loans; volatility in the securities markets that could adversely affect the value or credit quality of the Company’s assets, impairment of goodwill, or the availability and terms of funding necessary to meet the Company’s liquidity needs; changes in information technology and other operational risks, including cybersecurity and artificial intelligence, that require increased capital spending and introduce additional risk; changes in consumer spending and savings habits; changes in tax, banking, securities and insurance laws and regulations; the outcome of pending and future litigation and governmental proceedings, including tax-related examinations and other matters; changes in accounting policies, practices and standards; the effects of climate change on the Company and its customers, borrowers or service providers; the effects of civil unrest, international hostilities, including the continuation of conflict in the Middle East, or other geopolitical events; the effects of epidemics and pandemics; turmoil and volatility in the financial services industry; actions taken by governmental agencies to stabilize the financial system and the effectiveness of such actions; increases in deposit insurance assessments due to bank failures; changes to regulatory capital requirements; questions about the soundness of one or more financial institutions with which the Company does business; and the risks and uncertainties discussed in more detail in the “Risk Factors” section of the Company’s Annual Report on Form 10-K for the year ended December 31, 2025, and subsequent filings with the Securities and Exchange Commission (the “SEC”). Factors other than these risks could also materially affect the Company’s financial results and performance, and the readers should not consider the risks described above to be a comprehensive description of all potential risks and uncertainties that affect the Company. Readers should not place undue reliance on our forward-looking statements. The Company does not have any obligation to update forward-looking statements. This presentation includes non-GAAP financial measures to describe the Company’s performance. The Company uses these non-GAAP financial measures for purposes of measuring performance against the Company's peer group and other financial institutions, as well as for analyzing its internal performance. The Company also believes these non-GAAP financial measures help investors better understand the Company's operating performance and trends and allow for better performance comparisons to other banks. These non-GAAP financial measures also remove the impact of unusual items that may obscure trends in the Company’s underlying performance. These disclosures should not be viewed as a substitute for GAAP operating results, nor are they necessarily comparable to non-GAAP performance measures that may be presented by other financial institutions. Reconciliations to the comparable GAAP financial measures can be found by referring to the Company’s financial information filed with the SEC for the respective period.
