History
Pioneer Natural Resources was created in 1997 by the merger of Parker & Parsley Petroleum Company and MESA Inc., owned by Thomas Boone Pickens.
In May 2016, CEO and chairman Scott D. Sheffield was succeeded by Timothy Dove. Sheffield returned to the roles in 2019 after Dove's retirement. In January 2024, Richard P. Dealy was named as CEO.
Acquisition by ExxonMobil
In May 2024, in the largest merger in the petroleum industry in 20 years, Pioneer was acquired by ExxonMobil, making ExxonMobil the largest producer of shale gas in the Permian Basin.
Approval for the transaction from the Federal Trade Commission (FTC) was accompanied by a consent decree alleging that former Pioneer CEO Scott D. Sheffield colluded with OPEC to raise oil prices and making the merger conditional on Sheffield's being barred from joining ExxonMobil's board of directors or serving as an advisor to Exxon after the merger.
Antitrust lawsuit
In January 2024, a class action lawsuit was filed by drivers in three US states accusing Pioneer, along with seven other oil and gas producers, of an illegal price fixing scheme to constrain production of shale oil that led to American drivers paying more for gasoline than they would have in a competitive market. In May 2024, plaintiffs asked for the communications records of former CEO Scott Sheffield.
Philanthropy
Pioneer Natural Resources operated an extensive philanthropic program focused on education, disaster relief, and community development through various charitable initiatives and partnerships. In 2022, the company contributed nearly $8 million in social investments and employee-led giving to hundreds of charities in the Permian Basin and Dallas-Fort Worth area.
