As disclosed in Note 3 “Discontinued Operations,” on March 14, 2025, the Company completed the sale of Water Resources, which represented the Company’s contract drilling segment. The financial results of the Company’s contract drilling business has been presented as discontinued operations and therefore is excluded from segment reporting.

Additionally, through its wholly-owned subsidiaries, Barnwell was, until August 8, 2025, involved in several non-operated oil and natural gas investments in Oklahoma and Texas.
