Resilient Demand and Strategic Upgrades Drive XOM's Refining Success

By Debapriya Bhowal | December 31, 2025, 10:35 AM

Exxon Mobil Corporation XOM, an integrated energy giant, has a presence in several business segments, including upstream, refining and chemicals. XOM’s refining business has reported significant gains on the back of strong refining margins this year. The gains from its refining segment have supported earnings growth in the third quarter.

ExxonMobil stated that refining margins have strengthened due to two major factors: cheaper feedstock resulting from lower crude prices and the tightening of product supply caused by refinery outages and supply chain disruptions. In line with the resilient demand for petroleum products, ExxonMobil has focused on high-grading its refinery network while making investments in high-quality sites that have lower costs and diverse product offerings. Therefore, the company now operates fewer refineries that are efficient at converting raw crude into high-value petroleum products. This ensures that its refining system can remain competitive across various market cycles.

Apart from streamlining its refinery network, the company has also invested in upgrading the output from its refineries. In its latest earnings call, the company stated that it is taking the least valuable products from raw crude and investing in the conversion capacity to deliver high-value products. The Singapore CRISP project is a recent example of these initiatives, in which XOM took extremely low-value products like residue and fuel oil and converted them into high-value, profitable products such as lubricant base stocks and additional diesel using a proprietary new-to-the-world process.

ExxonMobil’s focus on high-grading its refinery system and investments in upgrading refinery output should enable it to remain competitive across market cycles.
