Net cash provided by operating activities. Net cash provided by operating activities for the six months ended June 30, 2025 was $126.3 million compared with net cash provided by operating activities for the six months ended June 30, 2024 of $496.2 million. The decrease in cash provided by operating activities in the six months ended June 30, 2025 when compared to the same period in 2024 is primarily a result of lower average realized oil and gas prices, lower sales volumes in Ghana and higher oil and gas production costs related to the ramp-up of LNG production at the GTA Phase 1 project for the six months ended June 30, 2025.

If an event of default exists under the Facility, the lenders can accelerate the maturity and exercise other rights and remedies, including the enforcement of security granted pursuant to the Facility over certain assets. In July 2025, the Company and the Facility lenders agreed to amend the debt cover ratio required under the Facility. The amendment makes this covenant less restrictive for the next two scheduled financial covenant assessment dates in September 2025 and March 2026, up to a maximum of 4.0x and 4.25x, respectively, and thereafter returns to the originally agreed upon ratio of 3.50x for assessment dates thereafter. The change is intended to align the covenant calculation with recent business operations, lower oil prices and the impact of pre-production operating costs associated with the GTA Phase 1 project on our results of operations. We were in compliance with the financial covenants contained in the Facility as of March 31, 2025 (the most recent assessment date). The Facility contains customary cross default provisions.
