(1) Kodiak Gas Services, Inc. (NYSE: KGS) (“Kodiak”) acquired CSI Compressco LP (“CSI Compressco”) on April 1, 2024.

CarbonFree Chemicals Holdings LLC (“CarbonFree”) is a carbon capture company with patented technologies that capture CO2 and mineralize emissions to make commercial, carbon-negative chemicals. In December 2021, we invested $5.0 million in a convertible note issued by CarbonFree. During the three month period ended March 31, 2024, the convertible note agreement was amended and, in connection with that amendment, note holders agreed to defer their right to electively convert the convertible notes to common units of CarbonFree (“CarbonFree Units”) for two years. In exchange for the amendment, we received CarbonFree Units representing less than 1% of the CarbonFree Units outstanding as of September 30, 2024. The CarbonFree 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 by CarbonFree is limited to our investment, including capitalized and accrued interest associated with the CarbonFree convertible note and CarbonFree Units.

KMX Technologies (“KMX”) is advancing wastewater treatment and accelerating energy storage with its direct lithium recovery enhancement processes through its proprietary membrane distillation technology. During 2023, we invested $0.4 million in convertible notes issued by KMX. During the three months ended September 30, 2024, these convertible notes converted into preferred units and we invested $1.0 million in additional preferred units. We also received common units issued by KMX. The KMX preferred units and common units are not publicly traded and may not be offered, sold, transferred or pledged until such preferred units or common units are registered pursuant to an effective registration statement or pursuant to an exemption from registration.

We are party to agreements whereby Standard Lithium Ltd. (NYSE: SLI) (“Standard Lithium”) has the rights to produce and extract lithium in a portion of our Arkansas leases. The Company received and currently holds 800,000 shares of common stock of Standard Lithium under the terms of its arrangements.
