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 a December 2025 update, management stated that it now expects annual synergies from the acquisition to total $4 billion.
Like Chevron, ExxonMobil has demonstrated a long commitment -- 43 consecutive years -- to increasing the capital it returns to shareholders by way of a dividend. ExxonMobil is pursuing share buybacks as a way to grow shareholder value. In addition to the $16.7 billion in dividends that the company paid on its common stock, ExxonMobil also repurchased more than $19 billion in stock during 2024.
ExxonMobil continued its work to strengthen its balance sheet, ending the third quarter of 2025 with a debt-to-capital ratio of 13.5%. 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 in a secure position to continue its streak of raising its dividend.
