History of CNB Financial 1865: County National Bank of Clearfield established 1934: Reorganizes through a stock offering to existing depositors 1984: Forms CNB Financial Corporation holding company 2005: ERIEBANK is formed 2005: Purchases assets of Holiday Consumer Discount Company and forms Holiday Financial Services Corporation 2006: Conversion to a state banking charter 2010: Joseph Bower becomes CEO after retirement of William Falger 2008-2009: Receives approval to raise $21 million via TARP; CNB chooses not to participate 2010: Common Equity raise of $34.5 million 2013: Acquisition of FC Banc Corp. headquartered in Bucyrus, Ohio with $360 million in assets 2015: 150th Anniversary Celebration 2016: Acquisition of Lake National Bank headquartered in Mentor, Ohio with $153 million in assets 1865 1934 1984 2005 2006 2008 2009 2010 2013 2015 2016 2016: Subordinated Debt raise of $50 million

CNB’s Growth Model CNB’s strong growth, both organic and by M&A, has been a result of its business model which involves identifying the right market in which to operate based on market demographics that fit CNB’s lending expertise (small and mid-sized commercial and industrial lending) and then finding the right local person with market experience to deliver the CNB product set and sophistication of services to grow organically in the market CNB created its ERIEBANK franchise using this model and grew to over $500 million in loans in ten years In Ohio, CNB entered the greater Columbus market through its acquisition of FCBank but has since executed this same strategy to grow organically in the FCBank market through new offices and additional lenders The same opportunity exists in the greater Cleveland, OH market with CNB’s recent acquisition of Lake National Bank CNB has recently hired a local banker to oversee its entrance into Buffalo, New York with Bank on Buffalo M&A is not a priority in CNB’s growth strategy; however, it will remain opportunistic and would consider transactions that would meet its financial criteria and also expand its presence into new markets that fit its business model (e.g. FCBank, Lake National); bring significant talent; and/or fill in existing markets CNB raised $50 million of BBB- Kroll rated subordinated debt during the third quarter of 2016 to support its organic growth strategy

Market Overview Erie is the 4th largest city in Pennsylvania. Erie's vibrant business community is growing increasingly more diverse. The region's strong manufacturing history has helped encourage recent growth in smaller-scale steel and plastics manufacturers, as well as healthcare, insurance, tourism and education industries. The Erie region's largest employer, GE Transportation, maintains its world headquarters facility in Erie, Pennsylvania and is the largest employer in Erie, PA. Lord Corporation was founded in Erie and maintains major operations in the region. Diesel-electric locomotive building remains the largest manufacturer sector in Erie. More than 10% of American plastics are manufactured or completed in Erie-based plastics plants. Columbus' diversified economy is balanced among the services, trade, government, and manufacturing sectors. In the Columbus Region, manufacturing is thriving with more than 1,700 manufacturers employing more than 85,000 people. Hundreds of thousands of goods roll off production lines every day—from automobiles and fertilizer to beer and baby formula. Mentor is one of Northeast Ohio’s largest communities and the largest city in Lake County with a population of over 45,000. There are approximately 2,570 businesses located in Mentor and more than 34,000 employees working in a diverse range of businesses including major corporations, manufacturers, retailers, specialty shops and small businesses. Mentor, which serves as a retail hub for many of the eastern suburbs of Cleveland, ranks seventh in Ohio for total retail sales with approximately 600 stores and 3.3 million square feet of prime retail space.

Market Overview Source: Deposit market share at June 30, 2016. Pro forma to include Lake National Bank

At September 30, 2016: Ten branches One loan production office in Ashtabula, Ohio Entered the greater Cleveland market with the acquisition of Lake National Bank in Q3 2016, which allows for continued organic growth without needing new acquisitions (similar to our entry into Columbus) Logical market extension of ERIEBANK franchise Demographically attractive market with significant organic growth potential; One of very few community banks in a market dominated by larger institutions; and Known for its mid-sized commercial and industrial businesses, which is a core strength of CNB and a market it knows well. $658 million in loans and $752 million in deposits; organic loan growth of $49.9 million, or 10.3% since September 30, 2015 ERIEBANK, a division of CNB Bank, was created de novo in 2005

The acquisition of FC Banc Corp. in 2013 expanded CNB’s geographic footprint into Central Ohio with meaningful size and scale $345 million in loans and $349 million in deposits as of September 30, 2016 Loan growth of $59.9 million, or 21.0%, since September 30, 2015 Opportunity to replicate CNB’s already successful ERIEBANK model in a market conducive to CNB’s business plan Significant opportunity for both organic and strategic growth going forward Addition of C&I lenders who focus in the Columbus and Lancaster areas Successful Expansion into Ohio

Building Infrastructure to Support Future Growth CNB has experienced significant growth, doubling its size since December 31, 2009, assets have grown to $2.5 billion at September 30, 2016 from $1.2 billion at December 31, 2009 The rapid increase in assets through the growth in number of customers led management to analyze its infrastructure to determine how much it could continue to grow with the current complement of people and staff As a result, CNB made numerous infrastructure, personnel, and other investments during 2015 and early 2016 to facilitate its continued growth: A building project was completed which added approximately 15,000 square feet of space to our existing headquarters to better leverage our facilities, technology, and personnel. This new modern facility allows us to house our back-office staff to operate well into the foreseeable future; CNB added 27 full-time equivalent staff, which included both customer-facing personnel such as business development and wealth management officers, as well as support department personnel; and Upgraded its core processing system which involved some non-recurring costs in 2015 ($108 thousand) and 2016 ($1.6 million). With these investments, CNB now has the infrastructure in place to support its continued growth

Customer-Efficient, Cost-Effective Retail Delivery CNB’s branch network has evolved to more customer-friendly branches providing customers with a one-on-one experience Branches are staffed with employees that can handle all of a customer’s needs from account openings to customer service CNB recently completed an upgrade of its core processing system, along with most of its other electronic offerings, including enhancements to mobile and eBanking solutions to provide the most up-to-date services to its customers

Strong Capital Levels * Please see slide 29 for a reconciliation of non-GAAP financial information.

Non-GAAP Financial Reconciliation Tangible common equity, tangible assets and tangible book value per share are non-GAAP financial measures calculated using GAAP amounts. Tangible common equity is calculated by excluding the balance of goodwill and the core deposit intangible from the calculation of shareholders’ equity. Tangible assets is calculated by excluding the balance of goodwill and the core deposit intangible from the calculation of total assets. Tangible book value per share is calculated by dividing tangible common equity by the number of shares outstanding. CNB believes that these non-GAAP financial measures provide information to investors that is useful in understanding its financial condition because, in the case of the tangible common equity to tangible assets ratio, the ratio is an additional measure used to assess capital adequacy and, in the case of tangible book value per share, tangible book value per share is an additional measure used to assess the Corporation’s value. Because not all companies use the same calculations of tangible common equity and tangible assets, this presentation may not be comparable to other similarly titled measures calculated by other companies. A reconciliation of these non-GAAP financial measures is provided below (dollars in thousands, except share and per share data).
