USANA HEALTH SCIENCES INC

We are taking advantage of U.S. Securities and Exchange Commission (“SEC”) rules that allow us to deliver proxy materials to our shareholders on the Internet. Under these rules, on April 7, 2026, we mailed our shareholders a Notice of Internet Availability of Proxy Materials containing instructions on how to access our proxy materials, including this Proxy Statement and our Annual Report on Form 10-K for the fiscal year ended January 3, 2026 (“Fiscal Year 2025”). The Notice of Internet Availability of Proxy Materials also provides instructions on how to vote over the Internet, by mail or by telephone. If you received a Notice of Internet Availability of Proxy Materials by mail, you will not receive a printed copy of the proxy materials unless you specifically request these materials.

Internet distribution of proxy materials helps us expedite receipt of the materials by shareholders, lower the cost of our Annual Meeting, and reduce the environmental impact of our Annual Meeting. However, if you received a Notice of Internet Availability of Proxy Materials by mail and would like to receive a printed copy of the proxy materials, please follow the instructions for requesting those materials contained in the Notice of Internet Availability of Proxy Materials. If you have previously elected to receive our proxy materials electronically, you will continue to receive these materials via e-mail unless you elect otherwise.
