Item 8.01

Other Events.

As previously announced, on October 26, 2023, CapStar Financial Holdings, Inc., a Tennessee corporation (“CapStar”), entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Old National Bancorp, an Indiana corporation (“Old National”). The Merger Agreement provides that, upon the terms and subject to the conditions set forth therein, CapStar will merge with and into Old National (the “Merger”), with Old National as the surviving corporation in the Merger (the “Surviving Corporation”). Immediately following the Merger, or at such later time as Old National 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 Old National’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 CapStar and Old National.

In connection with the Merger Agreement, Old National filed a registration statement on Form S-4 with the U.S. Securities and Exchange Commission (the “SEC”) on January 3, 2024 (as amended on Form S-4/A on January 23, 2024, the “Registration Statement”), which contained a preliminary prospectus of Old National and a preliminary proxy statement of CapStar, and filed a definitive prospectus with the SEC on January 25, 2024 (the “Definitive Prospectus”). In addition, CapStar filed a definitive proxy statement with the SEC on January 25, 2024 (the “Definitive Proxy Statement”).

Litigation Relating to the Merger

Following the announcement of the Merger Agreement, as of February 15, 2024, one lawsuit challenging the Merger has been filed (the “Lawsuit”). The Lawsuit is captioned Stephen Bushansky v. CapStar Financial Holdings, Inc. et al. (Case No. 24-0025-I ) and was filed in the Chancery Court for the State of Tennessee in the 20th Judicial District at Nashville. The Lawsuit alleges, among other things, that CapStar and its directors failed to disclose material facts in relation to the Merger in violation of Tennessee law, CapStar’s directors breached their fiduciary duties under Tennessee law and Old National aided and abetted in the breach of those duties. The Lawsuit seeks, among other things, an injunction preventing the consummation of the Merger. In addition, CapStar has received demand letters from counsel representing individual shareholders of CapStar (the “Demand Letters” and together with the Lawsuit, the “Matters”). The Demand Letters generally allege that the Registration Statement and/or the Definitive Proxy Statement omits certain information in relation to the Merger.

CapStar and Old National believe that the claims asserted in the Matters are without merit and that supplemental disclosures are not required or necessary under applicable laws. However, in order to avoid the risk that the Matters delay or otherwise adversely affect the Merger, and to minimize the costs, risks and uncertainties inherent in litigation, and without admitting any liability or wrongdoing, CapStar is supplementing the Definitive Proxy Statement as described in this Current Report on Form 8-K. CapStar, Old National and the other named defendants deny that they have violated any laws or breached any duties to CapStar’s shareholders. Nothing in this Current Report on Form 8-K shall be deemed an admission of the legal necessity or materiality under applicable laws of any of the disclosures set forth herein, taken individually or in the aggregate. To the contrary, CapStar and Old National specifically deny all allegations in the Matters that any additional disclosure was or is required.

Supplemental Disclosures

The supplemental disclosures set forth below should be read in conjunction with the Definitive Proxy Statement, which should be read in its entirety. Page references in the below disclosures are to pages in the Definitive Proxy Statement, and defined terms used but not defined herein have the meanings set forth in the Definitive Proxy Statement. To the extent the following information differs from or conflicts with the information contained in the Definitive Proxy Statement, the information set forth below shall be deemed to supersede the respective information in the Definitive Proxy Statement. For clarity, new text within restated paragraphs and tables from the Definitive Proxy Statement is bold and underlined, while deleted text is bold and stricken-through.

The sub-section of the Definitive Proxy Statement entitled “Opinion of CapStar’s Financial Advisor” is hereby amended and supplemented as follows:

The following language and table are added above the table at the bottom of page 39:

The language under the heading “CapStar Dividend Discount Analysis” on page 40 is hereby amended and supplemented as follows:

Using the CapStar Street Forecasts for 2023, 2024 and 2025 and assuming, at the direction of CapStar management, 3.0% annual growth thereafter and that CapStar would make distributions of capital in excess of the amount necessary to achieve a 12.0% common equity Tier 1 ratio level, Morgan Stanley performed a dividend discount analysis for CapStar on a standalone basis (the “CapStar Dividend Discount Analysis”). For purposes of the CapStar Dividend Discount Analysis, aggregate dividend distributions by CapStar on shares of CapStar common stock were estimated, based on the foregoing, to be $11 million as of June 30, 2023, $16 million as of December 31, 2023, $15 million as of December 31, 2024, $9 million as of December 31, 2025, $19 million as of December 31, 2026, $20 million as of December 31, 2027 and $20 million as of December 31, 2028. Morgan Stanley calculated a range of implied values per share of CapStar common stock based on the sum of the discounted present values of (a) projected dividends on shares of CapStar common stock as of June 30, 2023 through December 31, 2028 and (b) a projected terminal value of CapStar common stock as of December 31, 2028.

Morgan Stanley based its analysis on a range of terminal forward multiples of 9.0x to 11.0x to the terminal year 2029 estimated forward earnings and 10.5% to 12.5% discount rates, using the capital asset pricing model. Utilizing the range of discount rates and terminal value multiples, Morgan Stanley derived an implied valuation range of present value indications per share of CapStar common stock ranging from $12.05 to $14.90 using the CapStar Street Forecasts.

With respect to the CapStar Dividend Discount Analysis, Morgan Stanley selected the range of discount rates of 10.5% to 12.5% upon the application of Morgan Stanley’s professional judgment and experience to reflect CapStar’s estimated cost of equity using a capital asset pricing model (a “CAPM”).

For purposes of deriving the terminal value of CapStar with respect to the CapStar Dividend Discount Analysis, Morgan Stanley selected a range of terminal forward multiples of 9.0x to 11.0x upon the application of Morgan Stanley’s professional judgment and experience, taking into account, among other factors, certain publicly available EPS multiples for the selected companies noted under the section entitled “—CapStar Public Trading Comparables Analysis” above.

The following language and table are added above the first table at the top of page 43:

The language under the heading “Old National Dividend Discount Analysis” on pages 43-44 is hereby amended and supplemented as follows:

Using the Old National Street Forecasts for 2023, 2024 and 2025 and assuming, at the direction of CapStar management, 3.0% annual growth thereafter and that Old National would make distributions of capital in excess of the amount necessary to achieve a 10.0% common equity Tier 1 ratio level, Morgan Stanley performed a dividend discount analysis for Old National on a standalone basis (the “Old National Dividend Discount Analysis”). For purposes of the Old National Dividend Discount Analysis, aggregate dividend distributions by Old National on shares of Old National common stock were estimated, based on the foregoing, to be $51 million as of June 30, 2023, $273 million as of December 31, 2023, $326 million as of December 31, 2024, $520 million as of December 31, 2025, $450 million as of December 31, 2026, $464 million as of December 31, 2027 and $478 million as of December 31, 2028. Morgan Stanley calculated a range of implied values per share of Old National common stock based on the sum of the discounted present values of (a) projected dividends on shares of Old National common stock as of June 30, 2023 through December 31, 2028 and (b) a projected terminal value of Old National common stock as of December 31, 2028.

Morgan Stanley based its analysis on a range of terminal forward multiples of 7.5x to 9.5x to the terminal year 2029 estimated forward earnings and 10.9% to 12.9% discount rates, using the capital asset pricing model. Utilizing the range of discount rates and terminal value multiples, Morgan Stanley derived an implied valuation range of present value indications per share of Old National common stock ranging from $15.14 to $18.79 using the Old National Street Forecasts.

With respect to the Old National Dividend Discount Analysis, Morgan Stanley selected the range of discount rates of 10.9% to 12.9% upon the application of Morgan Stanley’s professional judgment and experience to reflect Old National’s estimated cost of equity using a CAPM.

For purposes of deriving the terminal value of Old National with respect to the Old National Dividend Discount Analysis, Morgan Stanley selected a range of terminal forward multiples of 7.5x to 9.5x upon the application of Morgan Stanley’s professional judgment and experience, taking into account, among other factors, certain publicly available EPS multiples for the selected companies noted under the section entitled “—Old National Public Trading Comparables Analysis” above.

The section of the Definitive Proxy Statement entitled “The Merger” is hereby amended and supplemented as follows:

The following language is added below the last paragraph on page 52 as a new sub-section entitled “Certain Prospective Financial Information”:

Certain Prospective Financial Information

As discussed in the section entitled “—Opinion of CapStar’s Financial Advisor” above, CapStar directed Morgan Stanley to use the CapStar Street Forecasts and the Old National Street Forecasts (collectively, the “Street Forecasts”) for purposes of its opinion.

The CapStar Street Forecasts included forecasted (i) net income of $29 million, $28 million and $29 million, (ii) earnings per share of $1.40, $1.36 and $1.41 and (iii) risk weighted assets of $2.8 billion, $3.0 billion and $3.1 billion, respectively, for 2023, 2024 and 2025 for CapStar.

The Old National Street Forecasts included forecasted (i) net income of $594 million, $552 million and $554 million, (ii) earnings per share of $2.03, $1.84 and $1.86 and (iii) risk weighted assets of $37.6 billion, $39.9 billion and $40.2 billion, respectively, for 2023, 2024 and 2025 for Old National.

The inclusion of the Street Forecasts does not take into account any circumstances or events occurring after the date they were prepared and should not be regarded as an indication that any of CapStar, Old National, their respective advisors, or other representatives or any other recipient of this information considered, or now considers, the Street Forecasts to be necessarily predictive of actual future performance or events, that such forecasts will be achieved (particularly in light of the inherent risks and uncertainties associated with such forecasts) or that they should be construed as financial guidance, and they should not be relied on as such.

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, (3) the ability of CapStar and Old National to obtain required governmental approvals of the Merger, and (4) 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.
