NET SALES

Revenue declined from 2024 to 2025, primarily as a result of lower crude oil prices in the oil and gas segment, partially offset by increased sales volumes due to a full year of production in 2025 related to the CrownRock Acquisition, which closed in August 2024, and higher domestic natural gas prices. Additionally, midstream and marketing revenue improved year over year due to higher sulfur prices at Al Hosn and enhanced natural gas margins.

INCOME FROM EQUITY INVESTMENTS AND OTHER

Income from equity investments and other decreased in 2025, compared to 2024, primarily due to the Company’s proportionate amount of impairments and other charges recorded by its equity method investees.
