Item 7.01 Other Events.

In connection with the administration of the BancPlus Corporation Employee Stock Ownership Plan (the "Plan"), BancPlus Corporation (the "Company") periodically solicits an appraisal of the value of its common stock, par value $1.00 per share (the "Common Stock"), from an independent, third party appraiser. The appraised value of the Company's Common Stock as of June 30, 2025 was $67.25 per share.

Such appraised value was determined solely for purposes of the Plan's administration and is therefore subject to certain limitations, qualifications and assumptions and may not reflect the fair value of the Company's Common Stock and should not be relied on for any reason. While the Company may seek an adjusted valuation of its Common Stock in the future,neither the Company nor the Plan has any obligation to do so or, if the Company or the Plan obtains a new appraised value of the Company's Common Stock, to disclose the new appraised value of the Company's Common Stock.
