NNPC’s revenue falls by N636 billion to N4.34 trillion in May 2026, according to a report cited by The Punch. The decrease occurs despite claims of stable oil production during the period. The reports frame the development as a decline in overall revenue figures rather than a direct drop in output, implying that factors other than production volume are affecting earnings. While the articles highlight the size of the revenue reduction and the reported level of revenue for the month, they do not present detailed breakdowns of the drivers in the provided excerpts. Overall, the coverage indicates that NNPC’s financial performance deteriorates in May 2026 even as production remains steady, raising questions about pricing, revenue collection, operational costs, or related adjustments that could influence the company’s net receipts. The reports also reference an outlook for what the decline could mean going forward, though specific future projections are not detailed in the supplied text.
