Item 1.01 Entry into a Material Definitive Agreement.

On October 26, 2023, Old National Bancorp, an Indiana corporation (the “Company”), entered into an Agreement and Plan of Merger (the “Merger Agreement”) with CapStar Financial Holdings, Inc., a Tennessee corporation (“CapStar”). The Merger Agreement provides that, upon the terms and subject to the conditions set forth therein, CapStar will merge with and into the Company (the “Merger”), with the Company as the surviving corporation in the Merger (the “Surviving Corporation”). Immediately following the Merger, or at such later time as the Company may determine, CapStar’s wholly-owned subsidiary, CapStar Bank, a state bank chartered under the laws of the State of Tennessee, will merge with and into the Company’s wholly-owned subsidiary, Old National Bank, a national banking association (the “Bank Merger”), with Old National Bank as the surviving bank in the Bank Merger. The Merger Agreement was unanimously approved and adopted by the board of directors of each of the Company and CapStar.

Subject to the terms and conditions of the Merger Agreement, at the effective time of the Merger (the “Effective Time”), each share of common stock, $1.00 par value, of CapStar (“CapStar Common Stock”) outstanding immediately prior to the Effective Time, other than certain shares held by CapStar as treasury stock or shares owned by CapStar or the Company, will be converted into the right to receive, without interest, (a) 1.155 shares (the “Exchange Ratio”) of common stock, no par value, of the Company (“Company Common Stock” and such consideration is hereinafter referred to as the “Merger Consideration”) and (b) cash in lieu of fractional shares.

At the Effective Time, (i) each option to purchase shares of CapStar Common Stock that is outstanding immediately prior to the Effective Time, whether vested or unvested, will, automatically, and without any required action on the part of the holder thereof, be cancelled, with the holder of such option becoming entitled to receive, in full satisfaction of the rights of the holder with respect thereto, the Merger Consideration in respect of each share of CapStar Common Stock subject to such option, less the applicable exercise price and tax withholding; (ii) each award of a share of restricted CapStar Common Stock subject to vesting, repurchase or other lapse restriction, whether vested or unvested, that is outstanding as of immediately prior to the Effective Time will be assumed by the Company and converted into a restricted stock award with respect to the number of shares of Company Common Stock determined based on the Exchange Ratio, other than any such award held by a non-employee director, which will fully vest and be cancelled and converted into the right to receive the Merger Consideration in respect of each share of CapStar Common Stock underlying such award; (iii) each restricted stock unit award in respect of shares of CapStar Common Stock (other than any such award subject to performance-based vesting conditions) that is outstanding as of immediately prior to the Effective Time will be assumed by the Company and converted into a restricted stock unit award with respect to the number of shares of Company Common Stock determined based on the Exchange Ratio; and (iv) each performance-based restricted stock unit award in respect of shares of CapStar Common Stock that is outstanding as of immediately prior to the Effective Time, pursuant to its terms, will fully vest (with performance goals deemed achieved based on the greater of the target performance level or actual performance as determined by the board of directors of CapStar or its compensation committee) and will be cancelled and converted automatically (without any further action on part of the holder thereto) into the right to receive the Merger Consideration in respect of each share of CapStar Common Stock underlying such award.

The Merger Agreement contains customary representations and warranties from both the Company and CapStar, and each party has agreed to customary covenants, including, among others, covenants relating to the conduct of its business during the interim period between the execution of the Merger Agreement and the Effective Time. CapStar has agreed to call a meeting of its shareholders to consider a proposal to approve the Merger Agreement and the transactions contemplated thereby (“CapStar Shareholder Approval”) and, subject to certain exceptions, for the board of directors of CapStar to recommend that its shareholders vote in favor of such approvals. CapStar has also agreed to customary non-solicitation obligations relating to alternative acquisition proposals. CapStar and the Company have also agreed to use their reasonable best efforts to prepare and file all applications, notices and other documents to obtain all necessary consents and approvals for consummation of the transactions contemplated by the Merger Agreement.

The completion of the Merger is subject to customary conditions, including (1) receipt of CapStar Shareholder Approval, (2) the admission for listing on the Nasdaq Stock Exchange of the shares of Company Common Stock to be issued in the Merger, (3) receipt of required regulatory approvals, (4) effectiveness of the registration statement on Form S-4 for Company Common Stock to be issued in the Merger, and (5) the absence of any order, injunction, decree or other legal restraint preventing or making illegal the completion of the Merger, the Bank Merger or any of the other transactions contemplated by the Merger Agreement.

Each party’s obligation to complete the Merger is also subject to certain additional customary conditions, including (1) the accuracy of the representations and warranties of the other party, (2) performance in all material respects by the other party of its obligations under the Merger Agreement, (3) absence of a material adverse effect on the other party and (4) receipt by such party of an opinion from its counsel to the effect that the Merger will qualify as a “reorganization” within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended. Additionally, the Company’s obligation to close is subject to CapStar’s adjusted tangible shareholder’s equity as of the month-end prior to five business days before the closing date exceeding a specified minimum value.

The Merger Agreement provides certain termination rights for both the Company and CapStar and further provides that a termination fee of $11,250,000 will be payable by CapStar in the event of a termination of the Merger Agreement under certain limited circumstances following CapStar’s receipt of a bona fide acquisition proposal, including in the event that CapStar’s board of directors withdraws or adversely modifies its recommendation that its shareholders vote in favor of the Merger Agreement.

The representations, warranties and covenants of each party set forth in the Merger Agreement have been made only for purposes of, and were and are solely for the benefit of the parties to, the Merger Agreement; may be subject to limitations agreed upon by the contracting parties, including being qualified by confidential disclosures made for the purposes of allocating contractual risk between the parties to the Merger Agreement instead of establishing these matters as facts; and may be subject to standards of materiality applicable to the contracting parties that differ from those applicable to investors. Accordingly, the representations and warranties may not describe the actual state of affairs at the date they were made or at any other time, and investors should not rely on them as statements of fact. In addition, such representations and warranties (1) will not survive consummation of the Merger and (2) were made only as of the date of the Merger Agreement or such other date as is specified in the Merger Agreement. Moreover, information concerning the subject matter of the representations and warranties may change after the date of the Merger Agreement, which subsequent information may or may not be fully reflected in the parties’ public disclosures. Accordingly, the Merger Agreement is included with this filing only to provide investors with information regarding the terms of the Merger Agreement, and not to provide investors with any other factual information regarding the Company or CapStar, their respective affiliates or their respective businesses. The Merger Agreement should not be read alone, but should instead be read in conjunction with the other information regarding the Company, CapStar, their respective affiliates or their respective businesses, the Merger Agreement and the Merger that will be contained in, or incorporated by reference into, the Registration Statement on Form S-4 that will include a prospectus of the Company and a proxy statement of CapStar , as well as in the Annual Reports on Form 10-K, Quarterly Reports on Form 10-Q, Current Reports on Form 8-K and other filings that each of the Company and CapStar makes with the Securities and Exchange Commission (“SEC”).

The foregoing description of the Merger Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of the Merger Agreement, which is attached hereto as Exhibit 2.1 and is incorporated herein by reference.

Item 8.01 Other Events.

Concurrently with the execution of the Merger Agreement, each of CapStar’s directors and an executive officer entered into a Shareholder Voting Agreement (each, a “Voting Agreement”) with the Company, pursuant to which the directors and such executive officer, in their capacity as shareholders of CapStar, have agreed, among other things, to vote their shares of CapStar Common Stock at CapStar’s special shareholder meeting in favor of approval of the Merger Agreement and the Merger. The foregoing description of the Voting Agreements does not purport to be complete and is qualified in its entirety by reference to the full text of the form of Voting Agreement, which is attached hereto as Exhibit 99.1 and is incorporated herein by reference.

FORWARD-LOOKING STATEMENTS

This Current Report on Form 8-K contains “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 proposed 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, (3) the ability of the Company and CapStar to obtain required governmental approvals of the Merger, and (4) the failure of the closing conditions in the definitive 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 “Forward-Looking Statements” (in the case of the Company), “Cautionary Note Regarding Forward-Looking Statements” (in the case of CapStar), and “Risk Factors” in the Company’s and CapStar’s Annual Reports on Form 10-K for the year ended December 31, 2022, and other documents subsequently filed by the Company or CapStar with the SEC.
