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 the presentation materials 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. 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 risk factors relating to the banking industry and the other factors detailed from time to time in Horizon’s reports filed with the Securities and Exchange Commission (the “SEC”), including those described in Horizon’s Annual Report on Form 10-K for the year ended December 31, 2020 and other subsequent filings with the SEC. Further, statements about the effects of the COVID-19 pandemic on our business, operations, financial performance, and prospects may constitute forward-looking statements and are subject to the risk that the actual impacts may differ, possibly materially, from what is reflected in those forward-looking statements due to factors and future developments that are uncertain, unpredictable, and in many cases beyond our control, including the scope and duration of the pandemic, actions taken by governmental authorities in response to the pandemic, and the direct and indirect impact of the pandemic on our customers, third parties, and us. 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 41-56. Important Information 2

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, one-time acquisition and other non-recurring costs and non-core items. 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.
