Tullow Oil lost a tax arbitration case against the Ghanaian government regarding a $196.5 million corporate income tax assessment. Proactive Investors reported that the International Chamber of Commerce tribunal ruled the assessment does not breach contractual protections in the company's petroleum agreements. The dispute stems from proceeds received by the company between 2016 and 2019 under its corporate business interruption insurance policy.

The company expressed disappointment with the decision on September 30, 2026, stating it would consider its next steps following engagement with the Government of Ghana. The tribunal further ruled that penalties amounting to 100% fell outside the scope of existing contractual protections. Ghana remains central to the company's operations as the location of its core producing assets, and this ruling confirms a significant cash outflow for the mid-cap producer.
