ExxonMobil expects stronger refining margins to provide a $4.5 billion boost to its third-quarter earnings compared with the previous three months, highlighting the different effects of volatile energy prices on its business.
The US energy company disclosed the estimate on Friday, 16 October 2026, ahead of its full financial results scheduled for 30 October.
According to a Reuters report published on 16 October, the expected improvement reflects higher margins earned from turning crude oil into fuels and other petroleum products.
However, the $4.5 billion figure is an estimated contribution from changes in refining margins. It does not represent the company’s total quarterly profit or a confirmed increase of that amount in overall earnings.
Why refining margins have increased
Refining margins broadly measure the difference between the cost of crude oil and the value of products made from it, including petrol, diesel, and aviation fuel.
When demand for refined fuels is strong or supplies are disrupted, the selling prices of those products can rise relative to crude oil costs.
That can improve refiners’ earnings, although their final profits also depend on operating expenses, production volumes, maintenance, and other market factors.
Refining margins have risen amid disruptions to global energy supplies linked to the conflict involving Iran and restrictions affecting shipments through the Strait of Hormuz.
Ukrainian attacks on Russian refineries have also contributed to pressure on fuel supplies.
These developments have supported refining margins even as crude oil prices have moved differently during the quarter.
ExxonMobil’s preliminary update indicates that its refining operations benefited from these market conditions.
The company also reported that the Iran conflict had not caused volume-related disruptions to its operations during the quarter.
Lower crude prices weigh on production earnings
While refining margins have improved, ExxonMobil’s upstream business faces a different financial picture.
Upstream operations involve exploring for and producing crude oil and natural gas. Their earnings are particularly sensitive to changes in the prices received for those products.
The company estimated that lower oil and liquids prices could reduce third-quarter upstream earnings by approximately $1.3 billion compared with the second quarter.
Reuters reported, using LSEG market data, that the average closing price of Brent crude declined by about 5.6% between the two quarters.
Lower crude prices can reduce the revenue producers earn from each barrel sold, even when production continues without major interruption.
ExxonMobil also indicated that higher natural gas prices could provide an offsetting benefit of approximately $300 million.
The estimates show why a large energy company can benefit from one part of the market while facing pressure in another.
Asset sales and other adjustments
ExxonMobil expects the disposal of certain upstream assets to contribute approximately $700 million to earnings.
That figure reflects the anticipated earnings effect of the transactions and should not be confused with the total cash proceeds from asset sales.
The company’s preliminary financial information also points to other adjustments that could affect the final results.
These include an estimated negative effect of about $2.5 billion from timing differences associated with the accounting treatment of certain transactions.
Such effects can arise when financial contracts are valued at quarter-end while related physical shipments are recognised in a different reporting period.
They are another reason why the refining margin benefit should not be treated as a direct increase in overall company profit.
A separate financial report published by Quartz also highlighted these timing effects in the company’s preliminary earnings outlook.
What the figures mean for energy markets
The contrast between refining and production earnings illustrates how changes in energy markets affect different businesses.
Oil producers generally benefit when crude prices rise, while refiners may gain when the prices of finished fuels increase faster than the cost of the crude they process.
An integrated company such as ExxonMobil operates across both activities, allowing gains in one segment to offset some of the pressure elsewhere.
However, higher refining margins do not automatically mean retail fuel prices will rise by the same amount.
Petrol and diesel prices also depend on local supply, distribution costs, taxes, exchange rates, and competition.
The wider energy industry is facing similar pressures.
In its third-quarter trading update reported by Reuters, BP also indicated that stronger refining margins were supporting its outlook, although its business performance and financial estimates differ from ExxonMobil’s.
The developments underline the influence of geopolitical tensions and disrupted energy trade on company earnings.
Full results expected on 30 October
ExxonMobil is scheduled to release its full third-quarter financial results on Friday, 30 October 2026.
The report will provide a clearer account of earnings across its production, refining, chemicals, and other operations.
Investors will be looking closely at whether the improvement in refining margins is sufficient to offset weaker crude oil prices and other financial adjustments.
The results will also show how the company’s preliminary estimates translate into its reported performance.
The $4.5 billion refining benefit is significant, but ExxonMobil’s final earnings will depend on the combined performance of its businesses rather than one favourable market movement.
