01 Other Events

Item 8.01 Other Events. On November 19, 2025, Plumas Bank, a wholly-owned subsidiary of Plumas Bancorp (the "Company"), completed the sale of two administrative offices in Quincy, California (the "Properties") to BBS Branch III, LLC, a Delaware limited liability company ("BBS"), for an aggregate cash purchase price of $5,550,000 pursuant to a previously announced Real Estate Purchase and Sale Agreement dated as of March 28, 2025 (the "Purchase Agreement"). Concurrent with the closing of the sale, Plumas Bank and Plumas Investor, LLC, a Delaware limited liability company and Plumas Quincy, LLL, a Delaware limited liability company entered into triple net lease agreements (the "Lease Agreements") pursuant to which the Bank will lease back the Properties sold. The Lease Agreements have an initial term of 15 years with three five-year renewal options. The Lease Agreements provide for annual rent of approximately $463,000 in the aggregate for both Properties, increasing by three percent per annum each year. The completed sale-leaseback transaction resulted in a pre-tax gain of approximately $5.5 million. The Company is evaluating a potential sale of a portion of its securities portfolio that is currently in a loss position that, if consummated, would offset some or all of the gain generated by the sale of the Properties the result of which is to more than offset the lease expense. The foregoing description of the Purchase Agreement and the Lease Agreements is a summary and is qualified in its entirety by the Purchase Agreement and Lease Agreements, which are filed as Exhibits 10.1, 10.2 and 10.3, respectively, to this report and are incorporated by reference.
