History
Marathon Oil shed its refining arm, built an Eagle Ford shale position, exited overseas assets, and was bought by ConocoPhillips in November 2024.
2011-2013: Splitting off refining, buying Eagle Ford
The record opens with a major reshaping. On June 30, 2011, Marathon Oil completed the spin-off of Marathon Petroleum Corporation (MPC), which held its former refining, marketing and transportation businesses. Shareholders received one MPC share for every two Marathon Oil shares, about 356 million MPC shares in total. Six directors moved to MPC's board, and Clarence Cazalot Jr. became chairman as well as CEO. The share count fell from 769 million at the end of 2009 to 710 million at the end of 2010, though the beats do not explain that change.
On November 1, 2011, Marathon completed the $3.6 billion purchase of Eagle Ford shale assets in Texas from Hilcorp Resources Holdings, LP, covering about 143,000 net acres. The agreement had been signed on May 31, 2011, shortly before the spin-off. The record for 2012 and 2013 is quiet.
2014-2019: Leaving overseas assets
From 2014 the story was one of selling assets outside the United States. On October 15, 2014, Marathon sold its Norwegian subsidiary to Det norske oljeselskap ASA for about $2.1 billion after adjustments. The sale included the operated Alvheim floating production vessel, and Norway had averaged about 80,000 barrels of oil equivalent a day net in 2013.
In March 2016 the company sold 145 million new shares at $7.65 each, and underwriters took a further 21.75 million, about 166.75 million new shares in all. This diluted existing holders; the share count rose from about 677 million at the end of 2015 to about 847 million a year later. The filing did not say how the money would be used.
In March 2017 Marathon agreed to sell its Canadian subsidiary, including a 20% non-operated stake in the Athabasca Oil Sands Project, to a Shell affiliate and Canadian Natural Resources for $2.5 billion. It expected non-cash impairment charges of about $4.8 to $5.0 billion. The sale closed on May 31, 2017, with $1.75 billion paid at closing and $750 million due in the first quarter of 2018. The same month it announced a $1.1 billion deal for about 70,000 net acres in the Permian basin, though the beats do not confirm that it closed. In July 2017 Marathon sold $1 billion of 4.40% notes due 2027 to redeem its 2017, 2018 and 2019 notes.
On March 1, 2018, it sold its 16.33% stake in Libya's Waha concessions to a Total S.A. subsidiary for $450 million. On July 1, 2019, it sold its U.K. subsidiaries to RockRose Energy PLC for about $95 million, reflecting the buyer taking on about $345 million of working capital and cash equivalents.
2020-2022: Downturn and a return to Eagle Ford
On May 6, 2020, citing the economic downturn, the board temporarily suspended the quarterly dividend. The company reported a first-quarter net loss of $46 million, cut its 2020 capital budget to $1.3 billion or less, and paused its share buyback. The record for 2021 is quiet, though the share count drifted lower through 2021 and fell to about 635 million by the end of 2022 without explanation in the beats.
On November 2, 2022, a Marathon subsidiary agreed to buy Ensign Operating's assets in Bee, DeWitt, Karnes and Live Oak Counties, Texas for $3.0 billion in cash. To help pay, Marathon signed a two-year, $1.5 billion term loan on November 22, 2022. The purchase closed on December 27, 2022, funded by cash on hand, the revolving credit facility and the term loan. The company said it believed the assets could hold output at 67,000 net barrels of oil equivalent a day with about one rig.
2024: Acquired by ConocoPhillips
On March 28, 2024, Marathon sold $1.2 billion of senior notes, $600 million due 2029 at 5.300% and $600 million due 2034 at 5.700%. With cash on hand, the proceeds were meant to repay the Ensign term loan in full, though the filings never confirmed that repayment.
On May 28, 2024, Marathon agreed to be acquired by ConocoPhillips, with each Marathon share converting into 0.2550 ConocoPhillips shares. A termination fee of $557 million applied in specified cases. On July 11 the FTC issued a Second Request for more information, extending the antitrust waiting period. The final proxy statement set a shareholder vote for August 29, 2024; the offer was worth about $28.27 per share on July 26, against about $30.33 on May 28.
The antitrust waiting period expired on November 20, and ConocoPhillips completed the acquisition on November 22, 2024. Marathon became a wholly owned ConocoPhillips subsidiary, and its directors and officers left. Its revolving credit facility and commercial paper program were paid off and terminated. ConocoPhillips guarantees the $1 billion Louisiana bonds and takes over Marathon's obligations around July 1, 2026. Marathon's shares were delisted, and on December 2, 2024 the company deregistered its securities, ending its obligation to file reports with the SEC. Outcomes of shareholder lawsuits and receipt of the $750 million deferred Canadian proceeds were not stated.
