Valero Energy CorporationValero Energy posted a net profit of $3.7 billion, more than fivefold increase, on surging refining margins.
Second-quarter 2025 earnings for US refiners stood out on surging refining margins. Valero Energy posted a net profit of 3.7 billion US dollars, a more than fivefold increase. HF Sinclair reported net profit of 892 million US dollars, up nearly four times, while PBF Energy swung to a net profit of 915 million US dollars from a net loss a year earlier. Phillips 66 and Marathon Petroleum are also expected to report strong results. For Thai refiners, although they too benefit from refining margins, each company's performance will differ, depending on refinery configuration, crude oil quality, production efficiency, price risk management, and inventory gains or losses in each period. In addition, refiners must shoulder rising hidden costs, such as crude oil premiums, freight rates, and higher insurance premiums driven by Middle East risk, which could add as much as 3 to 6 baht per litre. They also face risks from oil inventory losses, higher financing costs from increased working capital, pressure from government and social measures, and the need to invest in the clean energy transition under Net Zero targets and ESG standards. Key listed Thai companies with core oil refining operations include Thai Oil Public Company Limited, or TOP, Bangchak Corporation Public Company Limited, or BCP, Star Petroleum Refining Public Company Limited, or SPRC, and IRPC Public Company Limited, or IRPC, while PTT Global Chemical Public Company Limited, or PTTGC, has a refining business as part of its integrated structure.
