This Current Report on Form 8-K/A (this “Form 8-K/A”) amends the Current Report on Form 8-K of Hawthorn Bancshares, Inc. (the “Company”) originally filed by the Company with the Securities and Exchange Commission on April 29, 2026 (the “Original Form 8-K”). The sole purpose of this Form 8-K/A is to correct certain information contained in Exhibit 99.1 to the Original Form 8-K related to the Company’s financial results, as described below. The information in this Form 8-K/A, including Exhibit 99.1 furnished herewith, amends and supersedes the Original Form 8-K, including Exhibit 99.1 furnished therewith, in its entirety.

Item 2.02 Results of Operations and Financial Condition.

On April 29, 2026, the Company filed the Original Form 8-K to furnish a press release announcing its preliminary financial results for the quarter ended March 31, 2026. Subsequent to that release, and in connection with the Company’s normal quarter‑end close and review procedures, the Company identified an adjustment related to the recognition of a gain of $1.2 million associated with the sale and leaseback of property sold in March of 2026 for $1.9 million. The Company ultimately concluded certain contractual language constituted continuing involvement, thereby precluding the Company from applying sale-leaseback accounting as of March 31, 2026. The $1.9 million of proceeds will now be reflected as a financing obligation instead of a gain for the quarter ended March 31, 2026. As certain contractual obligations are resolved, the Company will re-evaluate the transaction under sale-leaseback accounting guidance and recognize any gain for the transaction in a future period when, and if, all such obligations are resolved.

As a result, certain financial results included in the previously furnished press release have been revised. The adjustments primarily resulted in a decrease to net income of $1.1 million and a decrease in earnings per share of $0.15 for the quarter ended March 31, 2026. The revised information is reflected in the revised press release furnished as Exhibit  99.1 to this Form 8‑K/A. The Company has also posted the revised press release to the Investor Relations section of its website.

The adjustments were identified and recorded prior to the Company’s issuance of its upcoming Form 10‑Q for the quarter ended March 31, 2026. The Company expects to include the revised financial information in its upcoming Form 10‑Q.

The information in this Item 2.02 and Exhibit  99.1 is being furnished and shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended, nor shall it be deemed incorporated by reference into any filing under the Securities Act of 1933, as amended, unless specifically stated otherwise.

Note Regarding Forward-Looking Statements

Certain statements in this Form 8-K/A constitute “forward-looking statements” within the meaning of the federal securities laws. These statements are based on management’s current opinions, expectations, beliefs, plans, objectives, assumptions or projections regarding future events or future results. Forward-looking statements include statements regarding the Company’s operations and financial results. These forward-looking statements are only predictions, not historical fact, and involve certain risks and uncertainties, as well as assumptions. Actual results, levels of activity, performance, achievements and events could differ materially from those stated, anticipated or implied by such forward-looking statements. While the Company believes that its assumptions are reasonable, it is very difficult to predict the impact of known factors, and, of course, it is impossible to anticipate all factors that could affect actual results. There are many risks and uncertainties that could cause actual results to differ materially from forward-looking statements made or implied herein including the risks discussed under the heading “Risk Factors” in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2025 filed with the Securities and Exchange Commission (“SEC”) on March 7, 2026, as well as other factors described from time to time in the Company's filings with the SEC. Such forward-looking statements are made only as of the date of this Form 8-K/A. The Company undertakes no obligation to publicly update or revise any forward-looking statement because of new information, future events or otherwise, except as otherwise required by law. If it does update one or more forward-looking statements, no inference should be made that the Company will make additional updates with respect to those or other forward-looking statements.
