Item 7.01 Regulation FD Disclosure
On October 6, 2026, Simpson Manufacturing Co., Inc. (the “Company”) is providing an operational and guidance timing update for the full year ending December 31, 2026.
This update reflects a shift in the anticipated closing timeline of the unimproved land in Stockton, California. Due to administrative procedures, the transaction which was originally scheduled to close in the third quarter of 2026, actually closed in the fourth quarter of 2026. Consequently, the net gain on disposal and its effect on income from operations will be recognized in the fourth quarter, rather than the third.
While the timing of the sale and the associated recognition of the net gain have shifted into the fourth quarter, the Company's full-year 2026 financial guidance ranges remain unchanged.
The information furnished pursuant to this Item 7.01 shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), nor shall it be deemed incorporated by reference in any filing under the Securities Act of 1933, as amended, or the Exchange Act, except as expressly set forth by specific reference in such a filing.
The information furnished pursuant to this Item 7.01 contains “forward-looking statements” within the meaning of the safe harbor provisions of the federal securities laws. It should be read in conjunction with the “Safe Harbor” statement contained in the Investor Presentation, the risk factors included in the Company’s periodic reports filed with the Securities and Exchange Commission and the other public announcements that the Company may make, by press release or otherwise, from time to time.
