Item 7.01 Regulation FD Disclosure.

On November 3, 2025, the Board of Directors of Lindsay Corporation (the “Company”) authorized a new share repurchase program of up to $150.0 million of common stock with no expiration date, which follows the completion of the Company's previously authorized $250.0 million share repurchase program. Under the program, shares may be repurchased from time to time in open market transactions at prevailing market prices and/or in privately negotiated transactions, as well as under formalized trading plans in accordance with the guidelines specified under Rule 10b5-1 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). The timing, volume, and nature of share repurchases will be at the discretion of management, and will depend on a number of factors, including the trading price of the Company's common stock, general market and business conditions, and applicable securities laws. This share repurchase program does not obligate the Company to acquire any particular amount of common stock, and it may be suspended or discontinued at any time. The Company's share repurchases in excess of issuances are subject to a 1% excise tax enacted by the Inflation Reduction Act.

A copy of a press release announcing the new share repurchase program is furnished herewith as Exhibit 99.1 and incorporated by reference into this Item 7.01.

In accordance with General Instruction B.2 of Form 8-K, the information contained in this Item 7.01, including Exhibit 99.1 attached hereto, is being “furnished” and, as such, shall not be deemed to be “filed” for purposes of Section 18 of the Exchange Act, or otherwise subject to liabilities of that Section, nor shall such information and exhibit be deemed incorporated by reference into any filing under the Securities Act of 1933, as amended, or the Exchange Act, except as shall be expressly set forth by specific reference in such a filing.
