**Item 8.01&nbsp;&nbsp;&nbsp;&nbsp;Other Events.**

As previously announced, on December 7, 2025, Home BancShares, Inc. ("Home" or the "Company"), its wholly-owned bank subsidiary, Centennial Bank, an Arkansas state bank ("Centennial"), and Home's wholly-owned subsidiary HOMB Acquisition Sub IV, Inc. entered into an Agreement and Plan of Merger (the "Merger Agreement") with Mountain Commerce Bancorp, Inc., a Tennessee corporation ("MCBI"), and its wholly-owned bank subsidiary, Mountain Commerce Bank, a Tennessee state banking corporation ("MCB"), under which Home and Centennial will acquire MCBI and MCB. The Agreement provides that, in a series of transactions, MCBI will merge into Home, with Home as the surviving entity, and MCB will merge into Centennial, with Centennial as the surviving entity (collectively, the "Merger").

On January 13, 2026, Home filed with the Securities and Exchange Commission (the "SEC") a Registration Statement on Form S-4, File No. 333-292708, which registration statement was amended on January 29, 2026, with the filing of Amendment No. 1 thereto (such registration statement, as so amended, the "Registration Statement"). The Registration Statement, which was declared effective by the SEC on January 30, 2026, included as a part thereof, a proxy statement of MCBI and a prospectus of Home (the "proxy statement/prospectus"). MCBI mailed the proxy statement/prospectus to its shareholders on or about January 30, 2026.

Following the announcement of the Merger Agreement, Home and MCBI received two requests from purported MCBI shareholders requesting supplemental disclosures relating to the proposed transaction. While Home and MCBI specifically deny that any supplemental disclosure was or is required or necessary under applicable laws, to avoid the risk of delay of the proposed transaction, to minimize potential expense, uncertainties and distraction, and to provide additional information to MCBI's shareholders, Home and MCBI are making the additional disclosures as described in this Current Report on Form 8-K. Nothing in this Current Report on Form 8-K shall be deemed to be an admission of the legal necessity or materiality under applicable laws of any of the disclosures set forth herein.

**SUPPLEMENTAL DISCLOSURES TO PROXY STATEMENT/PROSPECTUS**

*The additional information (the "supplemental disclosures") in this Current Report on Form 8-K supplements the disclosures contained in the proxy statement/prospectus and should be read in conjunction with the proxy statement/prospectus, which should be read in its entirety. To the extent that information set forth in the supplemental disclosures differs from or updates information contained in the proxy statement/prospectus, the information contained in this Current Report on Form 8-K shall supersede and supplement the information contained in the proxy statement/prospectus. Any page references in the information below are to pages in the proxy statement/prospectus, and terms used below have the meanings set forth in the proxy statement/prospectus, unless otherwise defined below. Paragraph references used herein refer to the proxy statement/prospectus before any additions or deletions resulting from the supplemental disclosures included herein.* 

**Background of the Merger**

**1.*The disclosure in the proxy statement/prospectus under the heading "The Merger – Background of the Merger" that begins on page 27 of the proxy statement/prospectus is hereby supplemented by adding the following paragraph as a new paragraph between the fifth and sixth paragraphs on page 29:***

All but one of the nondisclosure agreements entered into by MCBI with the fifteen companies with whom MCBI shared information or engaged in discussions regarding a potential transaction during the first quarter of 2025 included a standstill provision prohibiting the company signing the nondisclosure agreement from, for a period of twelve months from the date of the nondisclosure agreement, offering to purchase shares of MCBI or entering into a merger or other business combination transaction involving MCBI and from requesting that MCBI waive any of the standstill provisions included in the nondisclosure agreement, in each case, unless specifically authorized in writing in advance by an authorized representative of MCBI. Accordingly, not until the standstill provision included in an applicable nondisclosure agreement expired could a party to the nondisclosure agreement containing such a provision approach MCBI in order to present an offer to acquire MCBI in a consensual merger or other form that might constitute a superior proposal under Section 5.10 of the Merger Agreement. As of the date of the proxy statement/prospectus, the standstill provisions in all but three of the nondisclosure agreements containing a standstill provision had expired, with two of those having expired prior to the date on which the Merger Agreement was executed. Two of the standstill provisions that remained in effect as of the date of the proxy statement/prospectus expired on February 3, 2026, and February 6, 2026, respectively. As of March 1, 2026, only one standstill provision in a nondisclosure agreement remains in effect. That standstill provision, which is included in the nondisclosure agreement dated March 6, 2025, will expire on March 6, 2026.

As of March 1, 2026, since the announcement of the Merger, none of the companies that were a party to a nondisclosure agreement have contacted MCBI regarding a potential acquisition or other business combination transaction involving MCBI.

**10.*The disclosure under the heading "The Merger – Certain Unaudited Prospective Financial Information" is hereby supplemented by adding the following disclosure directly following the table at the bottom of page 56 of the proxy statement/prospectus:***

*Certain Unaudited Prospective Financial Information of Home*

In connection with the proposed transaction, for purposes of performing the financial analyses described above under "The Merger—Opinion of Hovde Group, LLC, Financial Advisor to Home," Home senior management provided to Hovde certain unaudited prospective financial information consisting of certain publicly available consensus analyst estimates with respect to Home. A summary of these estimates is set forth below.

This non-public unaudited prospective financial information was not prepared with a view toward public disclosure or with a view toward complying with the guidelines established by the American Institute of Certified Public Accountants with respect to prospective financial information or published guidelines of the SEC regarding forward-looking statements or GAAP. A summary of certain significant elements of the unaudited prospective financial information provided to Hovde by management of Home is set forth below, and is included in this proxy statement/prospectus because such information was used by Hovde in connection with the preparation of its fairness opinion. The information included below does not comprise all of the prospective financial information provided by Home to Hovde.

Although the financial forecast information set forth below is presented with numeric specificity, such information reflects numerous estimates and assumptions made by the independent equity research analysts who prepared the individual forecast estimates from which these consensus estimates were derived. Such estimates and assumptions involve judgments with respect to various factors, which may include, among other things, the future interest rate environment and other economic, competitive, regulatory and financial market conditions and future business decisions that may not be realized and that are inherently subject to significant business, economic, competitive and regulatory uncertainties and contingencies, including, among other things, the inherent uncertainty of the business and economic conditions affecting the industries in which Home operates, and the risks and uncertainties described under "Cautionary Note Regarding Forward-Looking Statements," and "Risk Factors," all of which are difficult to predict and many of which are outside the control of Home and will be beyond the control of the combined company. There can be no assurance that the underlying assumptions would prove to be accurate or that the projected results would be realized, and actual results likely would differ materially from those reflected in the financial forecasts, whether or not the merger is completed. Further, these assumptions do not include all potential actions that management could or might have taken during these time periods. In addition, since the prospective financial information covers multiple years, such information by its nature becomes subject to greater uncertainty with each successive year. The inclusion of this prospective financial information should not be regarded as an indication that any of Home, MCBI, their respective affiliates, officers, directors, advisors or other representatives considered, or now consider, this prospective financial information to be material information to any MCBI shareholder, particularly in light of the inherent risks and uncertainties associated with such prospective financial information, or that it should be construed as financial guidance, and it should not be relied on as such. In addition, the unaudited prospective financial information set forth below was prepared on or prior to December 2, 2025 and was based on facts and uncertainties that existed at the time such information was prepared, such as the uncertainty of the future interest rate environment, the Federal Reserve's possible actions relating to interest rates and monetary policies and other economic factors, and does not contemplate events or actions taken by Home subsequent to the time it was prepared.

The inclusion of the unaudited prospective financial information below should not be regarded as an indication that Home, MCBI, Piper Sandler or Hovde considered, or now consider, these projections and forecasts to be a reliable predictor of future results.

The prospective financial information is not fact and should not be relied upon as being necessarily indicative of future results, and this information should not be relied on as such, and readers of the proxy statement/prospectus are cautioned not to place undue reliance on the prospective financial information. No assurances can be given that these financial forecasts and the underlying assumptions are reasonable or that, if they had been prepared as of the date of this proxy statement/prospectus, similar assumptions would be used.

By including this summary of certain financial forecasts, neither Home nor MCBI nor any of their respective representatives has made or makes any representation to any person regarding the ultimate performance of Home or MCBI compared to the information contained in the financial forecasts. **Neither Home, MCBI nor, after completion of the merger, the combined company undertakes any obligation to update or otherwise revise the financial forecasts or financial information to reflect circumstances existing since their preparation or to reflect the occurrence of subsequent or unanticipated events, even in the event that any or all of the underlying assumptions are shown to be in error, or to reflect changes in general economic or industry conditions.**

------

The summary of the unaudited prospective financial information provided by Home is being provided because such information was considered in connection with the merger and was used by Home's financial advisor.

The unaudited prospective financial information set forth below constitutes forward-looking statements. For more information on factors which may cause future financial results to materially vary from those projected in the forecasts, see "Where You Can Find More Information," "Cautionary Note Regarding Forward-Looking Statements" and "Risk Factors" in this proxy statement/prospectus.

The following table presents selected unaudited prospective financial information of Home on a standalone basis (without giving effect to the proposed merger) provided for the periods indicated as of December 2, 2025:
