BP reported on Oct. 30, 2026, that its third-quarter underlying replacement-cost profit soared as stronger refining margins and improved trading lifted results. Management cautioned that fourth-quarter trading and throughput are typically weaker.
Q3 Results and Drivers
BP’s underlying replacement-cost profit reached $8.5 billion in Q3 2026, up $2.7 billion from the prior quarter and well above the roughly $2.2 billion a year earlier. The company attributed the rise mainly to significantly higher realized refining margins and a stronger gas and marketing trading performance. The refining indicator margin climbed to $46.7 per barrel from $29.6 in Q2 and $15.8 a year earlier. Refinery availability improved to 96.5% from 94.7%, despite throughput falling to 1,396 thousand barrels per day after BP divested the Gelsenkirchen refinery on July 31.
Upstream production held steady at about 2.2 million barrels of oil equivalent per day, while plant reliability rose to 95.3% from 92.4%. Reported profit was $4.7 billion, up from $3.9 billion in the previous quarter.
Operating cash flow totaled $14.8 billion, supported by a $0.5 billion working-capital release. This strong cash generation helped reduce net debt by $8.4 billion to $13.9 billion at Sept. 30.
Cash Flow and Q4 Outlook
Management said fourth-quarter trading is typically weaker due to softer prices, higher maintenance, lower market volatility, and seasonally reduced customer volumes. The company described its Q4 modeling inputs as assumptions rather than forecasts. It expects cash-tax payments to rise by about $800 million compared with Q3.
BP anticipates lower fourth-quarter production, including a roughly 20,000 barrels-per-day impact from the Gulf of Mexico. Refining throughput is expected between 1,160 and 1,210 thousand barrels per day, down from Q3 levels, reflecting the Gelsenkirchen divestment and increased maintenance. Full-year capital spending implies Q4 capital expenditure will be $1.0 billion to $1.5 billion higher than in Q3. The anticipated completion of the Castrol transaction will also affect Q4 earnings and cash flow.
BP’s Q3 materials and earnings discussion referenced a strategy update planned for December. Entering that review with reduced net debt may give management greater flexibility on capital allocation and shareholder returns.
