2^nd QUARTER 2016 HIGHLIGHTS:

Evansville, Ind. (August 1, 2016) – Today Old National Bancorp (the “Company” or “Old National”) (NASDAQ: ONB) reported 2^nd quarter 2016 net income of $39.1 million, or $0.31 per share. These quarterly results compare to net income of $27.0 million in the 1^st quarter of 2016 and $26.2 million recorded in the 2^nd quarter of 2015.

Old National accomplished several strategic milestones during the 2^nd quarter. These include the sale of the ONB Insurance Group, Inc., d/b/a Old National Insurance (May 31); closing on the partnership with Anchor BanCorp Wisconsin Inc. (“Anchor”) (May 1); the early termination of our FDIC loss share agreements; and the continuation of rationalizing our branch franchise. Related to some of these actions, the following items were included in Old National’s 2^nd quarter financial results:

Also today, the Company announced its quarterly cash dividend of $0.13 per share. The dividend is payable September 16, 2016, to shareholders of record on September 1, 2016. For purposes of broker trading, the ex-date of the cash dividend is August 30, 2016.

“This was a quarter marked by significant milestones for Old National as we closed on our largest partnership to date, completed the sale of our Insurance group and ended our FDIC loss share agreement,” said Chairman and CEO Bob Jones. “These actions – coupled with solid organic loan growth and a continued focus on expense management – allowed us to continue to grow our business in spite of the economic challenges facing all U.S. financial companies. Our shareholders also benefitted by the increase in tangible book value even after the closing of our Anchor partnership.”

Committed to our Strategic Imperatives and 2016 Initiatives

Old National’s continued steady performance and strong credit and capital positions can be attributed to the Company’s unwavering commitment to the three strategic imperatives that have guided Old National for 11 years:

1. Strengthen the risk profile; 2. Enhance management discipline; and 3. Achieve consistent quality earnings.

Guided by these three strategic imperatives, Old National’s primary initiatives for 2016 are: 1. Continue to grow organic revenue; 2. Improve operating leverage; and 3. Prudent use of capital, all while maintaining a strong credit culture.

“Our ratio of allowance for loan and lease losses to total loans declined quarter to quarter with the addition of Anchor’s $1.6 billion loan portfolio,” noted Daryl Moore, Chief Credit Executive. “In accordance with current accounting practices, these acquired loans are recorded at fair value with no allowance recorded at the acquisition date. When we consider both our allowance for loan losses plus our purchase accounting marks, we believe we remain appropriately reserved, as demonstrated by the table below.”
