OLD NATIONAL BANCORP IN

CORPORATE DEVELOPMENTS IN FISCAL 2023

During 2023, Old National successfully navigated a challenging interest rate environment, as well as industry-wide liquidity pressures to end the year with record full-year results. Our peer-leading deposit franchise, disciplined loan growth, strong credit quality, well-managed expenses, and dedicated team members who are committed to our clients and communities drove these outstanding results. Highlights experienced in 2023 included:

•net income applicable to common shareholders of $565.9 million, or $1.94 per diluted common share;

•growth in deposits of 6%;

•net interest income increase of $175.2 million, reflective of the higher rate environment and loan growth;

•disciplined loan growth of 6%;

•granular, low-cost deposit franchise; loan to deposit ratio of 89%;

•well-managed expenses; and

•stable credit metrics, including net charge-offs to average loans of 0.17%.

Our net interest income increased to $1.5 billion during 2023, compared to $1.3 billion in 2022 driven by the higher interest rate environment and loan growth. Provision for credit losses decreased compared to 2022, reflective of provision expense associated with the First Midwest merger in 2022. In addition, provision for credit losses for 2023 was impacted by higher net charge-offs, loan growth and macroeconomic factors. Noninterest income decreased from $399.8 million in 2022 to $333.3 million in 2023 primarily due to a $90.7 gain on the sale of health savings accounts in the fourth quarter of 2022, partially offset by a gain on sale of Visa Class B restricted shares totaling $21.6 million in the fourth quarter of 2023 and the full-period 2023 impact of the First Midwest merger which occurred in February of 2022. Noninterest expense decreased $11.9 million in 2023 compared to 2022. Noninterest expense in 2023 included $28.7 million of merger-related expenses, a $19.1 million FDIC special assessment, $4.4 million of contract termination charges, $3.4 million of expenses related to the Louisville tragedy, and $1.6 million for property optimization. Noninterest expense in 2022 included $120.9 million of merger-related expenses and $26.8 million for property optimization. Excluding these expenses, noninterest expense in 2023 increased $78.8 million, reflective of the additional operating costs associated with the full-period 2023 impact of the First Midwest merger, higher FDIC assessment expense, and marketing campaigns.

On October 26, 2023, Old National announced that it entered into a definitive merger agreement pursuant to which Old National will acquire CapStar and its wholly-owned subsidiary, CapStar Bank, in an all-stock transaction. As of September 30, 2023, CapStar had approximately $3.3 billion of total assets, $2.3 billion of total loans, and $2.8 billion of deposits. The definitive merger agreement has been approved by the Board of Directors of each company. The transaction is anticipated to close in the second quarter of 2024 subject to the approval of CapStar shareholders.
