Oil-Dri Corp of America

We are holding the 2026 Annual Meeting virtually because we believe the virtual format will enable stockholders to attend and participate fully and equally, improve meeting efficiency and our ability to effectively communicate and engage with our stockholders and provide cost savings to us and our stockholders.

The 2026 Annual Meeting will provide the same rights and opportunities to participate as you would have at an in-person meeting. Stockholders of record of outstanding shares of our Common Stock (“Common Stock”) and of outstanding shares of our Class B Stock (“Class B Stock”) as of the close of business on October 12, 2026 (the “Record Date”) will be able to attend and participate online and submit questions during the 2026 Annual Meeting by visiting www.virtualshareholdermeeting.com/ODC2026.

To attend and participate in the 2026 Annual Meeting, you will need the 16-digit control number included on your Notice, proxy card, or voting instruction form. The 2026 Annual Meeting will begin promptly at 9:30 a.m. Central Time. We encourage you to access the 2026 Annual Meeting prior to the start time. Online access will begin at 9:15 a.m. Central Time.

If you do not have a 16-digit control number, you may still attend the 2026 Annual Meeting as a guest in “listen-only” mode. To attend as a guest, please access www.virtualshareholdermeeting.com/ODC2026 and enter the information requested on the screen to register as a guest. Please note that if you participate as a guest, you will not have the ability to ask questions, vote, or examine the list of stockholders during the 2026 Annual Meeting. After the 2026 Annual Meeting, an archived copy of the audio webcast will be posted on our website at www.oildri.com/investors and will remain available for at least one year following the 2026 Annual Meeting.

The virtual 2026 Annual Meeting platform is fully supported across browsers (Microsoft Edge, Firefox, Chrome, and Safari) and devices (desktops, laptops, tablets, and cell phones) running the most updated version of applicable software and plugins. Stockholders should ensure that they have a strong internet connection if they intend to attend and/or participate in the 2026 Annual Meeting.
