Item 1.01 Entry into a Material Definitive Agreement.

On May 11, 2026, Hills Bank and Trust Company ("Hills Bank"), a wholly-owned subsidiary of Hills Bancorporation (the "Company"), entered into an Agreement of Purchase and Sale (the "Agreement") for the acquisition of land and improvements consisting of approximately 19.2 acres, which is a portion of land commonly known as 200 and 500 ACT Drive, Iowa City, Iowa. The Company intends to use the Property to consolidate operational teams in a single location and to address long-term operational needs. The Company's headquarters will remain in Hills, Iowa.

The purchase price is $20,700,000. The transaction is subject to a number of standard real estate purchase conditions including any required regulatory approvals. Closing is scheduled for the first quarter of 2027. Other than the Agreement, there is no material relationship between the Company or Hills Bank and the Seller.

The foregoing summary of the Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of the Agreement, a copy of which is filed as Exhibit 10.1 hereto and incorporated herein by reference. Certain personally identifiable information, including notice addresses and contact information of individuals, has been omitted from the exhibit pursuant to Item 601(b)(10)(iv) of Regulation S-K because such information is not material and would likely cause competitive harm to the Company if publicly disclosed.

Forward-Looking Statements
This Current Report on Form 8-K contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995, including statements regarding the Company's intended use of the Property, anticipated closing date, and plans for future growth and operations. These statements are based on management's current expectations and are subject to risks and uncertainties that could cause actual results to differ materially, including the failure to obtain regulatory approval, the failure to satisfy conditions precedent to closing, adverse findings during the due diligence inspection period, and other risks described in the Company's filings with the Securities and Exchange Commission. The Company undertakes no obligation to update any forward-looking statement to reflect events or circumstances after the date of this report.
