PLUMAS BANCORP

Notice of Internet Availability

of Proxy Materials

To expedite delivery, reduce costs and decrease the environmental impact of our proxy materials, we are using an SEC rule that allows us to furnish proxy materials over the internet instead of mailing paper copies of those materials to each shareholder. As a result, beginning on or about April 4, 2024, shareholders were sent a Notice of Internet Availability (the “Notice”) containing instructions on how to access our proxy materials, including this proxy statement and the 2023 Plumas Bancorp Annual Report, which includes our Annual Report on Form 10-K for the year ended December 31, 2023, over the internet.

If you received the Notice this year, you will not receive paper copies of the proxy materials unless you request the materials by following the instructions in the Notice. The Notice is not a proxy card that can be submitted to vote your shares. Instead, the Notice instructs you on how to access and review all of the important information contained in the proxy materials. The Notice also instructs you on how to vote via the internet or by telephone. Shareholders who have requested paper copies of the proxy materials will receive printed copies in the mail.

If you receive more than one Notice, it means that your shares are registered differently and are held in more than one account. To ensure that all shares are voted, please either vote each account over the internet or by telephone or sign and return by mail all proxy cards.

If you received paper copies of the proxy materials this year, but in the future would like to receive only the Notice and access the proxy materials electronically, you can elect to do so by: (i) following the instructions provided in the proxy card, if your shares are registered in your name, or (ii) by contacting your broker, trustee, bank or other nominee, if you hold your shares in street name.
