FOR IMMEDIATE RELEASE

HORIZON BANCORP ANNOUNCES THREE-FOR-TWO STOCK SPLIT

Michigan City, Indiana (NASDAQ GS: HBNC) – Horizon Bancorp announced today that its Board of Directors has declared a 3-for-2 stock split on Horizon’s authorized and outstanding shares of common stock. Shareholders of record as of the close of business on October 31, 2016, the record date, will be entitled to receive an additional half share for each share of common stock held.

Shareholders will receive cash in lieu of any fractional share of common stock that they otherwise would have been entitled to receive in connection with the split, except that those shareholders participating in Horizon’s dividend reinvestment and stock purchase plans will have fractional shares of common stock credited to their accounts.  The price paid for fractional shares will be based on the average closing price of a share of common stock as reported on the NASDAQ Global Select Market for the five trading days immediately prior to the record date.

In connection with the 3-for-2 stock split, the Board of Directors has approved an amendment to Horizon’s Articles of Incorporation to increase the amount of both the issued and authorized common shares in the same proportion. The amendment will become effective upon approval by the Indiana Secretary of State, and the 44 million common shares presently authorized will become 66 million authorized common shares.

The additional shares issued in the stock split are expected to be distributed to shareholders on November 14, 2016. Horizon common shares are expected to begin trading on a split-adjusted basis on or about November 15, 2016, or such other date specified by NASDAQ.

Craig M. Dwight, Horizon’s Chairman and Chief Executive Officer, stated: “Horizon has a strong and stable shareholder base, and we appreciate the large number of long-term, loyal shareholders.  This split is intended to improve the liquidity for our stock by making more shares available in the marketplace, and to make our stock affordable and attractive to investors.  We believe Horizon offers the opportunity to invest in a growing community bank that has consistently offered an attractive cash dividend and solid growth.”

The stock split will increase Horizon’s outstanding shares from approximately 14.8 million shares prior to the split to approximately 22.2 million shares.
