As previously announced, on October 26, 2023, CapStar Financial Holdings, Inc. (“CapStar”) and Old National Bancorp (“Old National”) entered into an Agreement and Plan of Merger (the “Merger Agreement”) pursuant to which CapStar will merge with and into Old National, with Old National as the surviving corporation (the “Merger”). Following the Merger (on a date to be determined by Old National), CapStar Bank, a wholly-owned subsidiary of CapStar that is headquartered in Nashville, Tennessee, will merge with and into Old National Bank, a wholly-owned subsidiary of Old National, with Old National Bank as the surviving bank (the “Bank Merger”).

On February 20, 2024, the Board of Governors of the Federal Reserve System approved the Merger and the Office of the Comptroller of the Currency approved the Bank Merger. Completion of the Merger remains subject to approval by CapStar’s shareholders at a special meeting to be held on February 29, 2024, as well as the satisfaction of the other customary closing conditions set forth in the Merger Agreement. The Merger is currently expected to be completed on April 1, 2024.

The Merger Agreement is described in more detail in CapStar’s Current Report on Form 8-K filed with the U.S. Securities and Exchange Commission (the “SEC”) on October 31, 2023.

In addition, CapStar filed a definitive proxy statement with the SEC on January 25, 2024 (the “Definitive Proxy Statement”).

Forward-Looking Statements

This Current Report on Form 8-K may contain “forward-looking statements” within the meaning of the safe harbor provisions of the U.S. Private Securities Litigation Reform Act of 1995, Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. In general, forward-looking statements can be identified through use of words such as “may,” “believe,” “expect,” “anticipate,” “intend,” “will,” “should,” “plan,” “estimate,” “predict,” “continue” and “potential” or the negative of these terms or other comparable terminology, and include statements related to the expected timing, completion, financial benefits, and other effects of the Merger. Forward-looking statements are not historical facts and represent management’s beliefs, based upon information available at the time the statements are made, with regard to the matters addressed; they are not guarantees of future performance. Actual results may prove to be materially different from the results expressed or implied by the forward-looking statements. Forward-looking statements are subject to numerous assumptions, risks and uncertainties that change over time and could cause actual results or financial conditions to differ materially from those expressed in or implied by such statements.

Factors that could cause or contribute to such differences include, but are not limited to, (1) expected cost savings, synergies and other financial benefits from the Merger not being realized within the expected time frames and costs or difficulties relating to integration matters being greater than expected, (2) the ability of CapStar to obtain the necessary approval by its shareholders, and (3) the failure of the closing conditions in the Merger Agreement to be satisfied, or any unexpected delay in closing the Merger. Further information regarding additional factors that could affect the forward-looking statements can be found in the cautionary language included under the headings “Cautionary Note Regarding Forward-Looking Statements” (in the case of CapStar), “Forward-Looking Statements” (in the case of Old National) and “Risk Factors” in CapStar’s and Old National’s Annual Reports on Form 10-K for the year ended December 31, 2022, and other documents subsequently filed by CapStar or Old National with the SEC.
