ExxonMobil also operates unconventional, deepwater, heavy oil, and liquefied natural gas (LNG) assets -- a business that grew considerably larger after its acquisition of Pioneer Natural Resources in May 2024. With the acquisition complete, management expects Permian production to grow from 1.2 million barrels of oil equivalent per day in 2024 to about 2.5 million barrels of oil equivalent per day by 2030.
It has upwardly revised its expectations regarding synergies. In its fourth quarter 2025 financial results presentation, management stated it expects annual synergies from the acquisition to total $4 billion -- twice the original estimate.
Like Chevron, ExxonMobil has demonstrated a long commitment -- 43 consecutive years -- to increasing the capital it returns to shareholders through dividends. ExxonMobil is pursuing share buybacks to grow shareholder value. In addition to the $17.2 billion in dividends that the company paid on its common stock, ExxonMobil also repurchased more than $20 billion in stock during 2025.
ExxonMobil continued its work to strengthen its balance sheet, ending 2025 with a debt-to-capital ratio of 14%. That's significantly lower than the 21.4% ratio at the end of 2021 and the 29.2% figure at the end of 2020. With a more robust balance sheet, the company is well-positioned to continue its streak of dividend increases.
4. Kinder Morgan
As the largest energy infrastructure company in the S&P 500, Kinder Morgan is one of the more recognizable names among midstream companies. The self-proclaimed "largest independent transporter of petroleum products in North America" estimates it transports 2.4 million barrels of gasoline, jet fuel, diesel, natural gas liquids, and condensate daily through an expansive 9,500-mile network spanning North America.
