In January 2025, we sold our Kodiak Gas Services, Inc. (NYSE: KGS) (“Kodiak”) shares for proceeds of $19.0 million, net of transaction and broker fees. During the six months ended June 30, 2025, we recorded a net gain of $0.6 million from the sale of our Kodiak shares. We are party to agreements whereby Standard Lithium has the right to explore for, and an option to acquire the rights to produce and extract, lithium in our Arkansas leases and other additional potential resources in the Mojave region of California. The Company received stock of Standard Lithium under the terms of the arrangements. We also hold investments in convertible notes, common units and preferred units issued by two privately-held companies. These convertible notes, common units and preferred units are not publicly traded and may not be offered, sold, transferred or pledged until such common units are registered pursuant to an effective registration statement or pursuant to an exemption from registration. Our exposure to potential losses is limited to our investments, including capitalized and accrued interest associated with the convertible notes. See Note 7 - “Fair Value Measurements” for further information.
