E X C E P T I O N A L S E R V I C E • S E N S I B L E A D V I C E ® Forward-Looking Statements This presentation may contain forward–looking statements regarding the financial performance, business prospects, growth and operating strategies of Horizon Bancorp, Inc. and its affiliates (collectively, “Horizon”). For these statements, Horizon claims the protection of the safe harbor for forward–looking statements contained in the Private Securities Litigation Reform Act of 1995. Statements in this presentation should be considered in conjunction with the other information available about Horizon, including the information in the filings we make with the Securities and Exchange Commission (the “SEC”). Forward–looking statements provide current expectations or forecasts of future events and are not guarantees of future performance. The forward–looking statements are based on management’s expectations and are subject to a number of risks and uncertainties. We have tried, wherever possible, to identify such statements by using words such as “anticipate,” “estimate,” “project,” “intend,” “plan,” “believe,” “will” and similar expressions in connection with any discussion of future operating or financial performance. Although management believes that the expectations reflected in such forward–looking statements are reasonable, actual results may differ materially from those expressed or implied in such statements. Risks and uncertainties that could cause actual results to differ materially include: changes in the level and volatility of interest rates, changes in spreads on earning assets and changes in interest bearing liabilities; increased interest rate sensitivity; continuing increases in inflation; loss of key Horizon personnel; increases in disintermediation; potential loss of fee income, including interchange fees, as new and emerging alternative payment platforms take a greater market share of the payment systems; estimates of fair value of certain of Horizon’s assets and liabilities; changes in prepayment speeds, loan originations, credit losses, market values, collateral securing loans and other assets; changes in sources of liquidity; continuing risks and uncertainties relating to the COVID–19 pandemic and government responses thereto; legislative and regulatory actions and reforms; changes in accounting policies or procedures as may be adopted and required by regulatory agencies; litigation, regulatory enforcement, and legal compliance risk and costs; rapid technological developments and changes; cyber terrorism and data security breaches; the rising costs of cybersecurity; the ability of the U.S. federal government to manage federal debt limits; climate change and social justice initiatives; material changes outside the U.S. or in overseas relations, including changes in U.S. trade relations related to imposition of tariffs, Brexit, and the phase out of the London Interbank Offered Rate (“LIBOR”); the inability to realize cost savings or revenues or to effectively implement integration plans and other consequences associated with mergers, acquisitions, and divestitures; acts of terrorism, war and global conflicts, such as the Russia and Ukraine conflict; and supply chain disruptions and delays. These and additional factors that could cause actual results to differ materially from those expressed in the forward–looking statements are discussed in Horizon’s reports (such as the Annual Report on Form 10–K, Quarterly Reports on Form 10–Q, and Current Reports on Form 8–K) filed with the SEC and available at the SEC’s Internet website (www.sec.gov). Undue reliance should not be placed on the forward–looking statements, which speak only as of the date hereof. Horizon does not undertake, and specifically disclaims any obligation, to publicly release the result of any revisions that may be made to update any forward–looking statement to reflect the events or circumstances after the date on which the forward–looking statement is made, or reflect the occurrence of unanticipated events, except to the extent required by law. Non-GAAP Measures Certain non-GAAP financial measures are presented herein. Horizon believes they are useful to investors and provide a greater understanding of Horizon’s business without giving effect to non-recurring costs and non-core items. For each non-GAAP financial measure, we have presented comparable GAAP measures and reconciliations of the non-GAAP measures to those GAAP measures in the Appendix to this presentation. Please see slides 51-52. Important Information 2

Average cost of core funds includes average balances of non-interest bearing deposits and excludes prepayment penalties on borrowings. (See further in the Appendix for a reconciliation of these non-GAAP amounts to their GAAP counterparts.) Slides 50-51 Use of Non-GAAP Financial Measures • Certain information set forth in the presentation materials refers to financial measures determined by methods other than in accordance with GAAP. Horizon believes these non-GAAP financial measures are helpful to investors and provide a greater understanding of our business without giving effect to purchase accounting impacts and non-recurring costs. These measures are not necessarily comparable to similar measures that may be presented by other companies and should not be considered in isolation or as a substitute for the related GAAP measure.
