2016 HIGHLIGHTS:

4^th QUARTER VS. 3^rd QUARTER 2016 HIGHLIGHTS:

Evansville, Ind. (January 24, 2017) – Today Old National Bancorp (the “Company” or “Old National”) (NASDAQ: ONB) reported full-year 2016 net income of $134.3 million, or $1.05 per diluted share. This net income represents an increase of 15.0% over full-year 2015 net income of $116.7 million, or $1.00 per diluted share, and represents the highest yearly earnings in the Company’s history. The successful conversion and integration of the Company’s largest partnership, strong loan growth and consistently low credit metrics all contributed to this positive year-over-year performance.

For the 4^th quarter of 2016, Old National reported net income of $33.5 million, or $0.25 per diluted share. During the current quarter, Old National recognized $12.8 million in pre-tax deferred gains related to the repurchase of various bank properties. Also included in the 4^th quarter of 2016 were pre-tax pension termination charges of $9.8 million, pre-tax branch consolidation charges of $5.1 million, pre-tax merger and integration charges of $1.8 million and severance of $1.6 million. These quarterly results compare to net income of $34.7 million in the 3^rd quarter of 2016 and $32.0 million recorded in the 4^th quarter of 2015. The 3^rd quarter of 2016 contained $5.5 million in pre-tax merger and integration charges.

“A strong fourth quarter, driven by 6.1% annualized organic loan growth, capped a year of excellent growth for Old National,” said Chairman and CEO Bob Jones. “Not only did we increase our net income by 15% over 2015 while maintaining exceptional credit quality and increasing our tangible book value by nearly 9%, we accomplished all of this while expanding our franchise into Wisconsin with the largest partnership in our history.”

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 were: 1. Continue to grow organic revenue; 2. Improve operating leverage; and 3. Prudent use of capital, all while maintaining a strong credit culture.
