Marathon to become top US refiner with US$23b Andeavor buy

Marathon Petroleum Corp agreed to buy rival Andeavor for more than US$23 billion in a deal creating one of the largest global refiners that will benefit from access to booming US shale fields and growing US fuel export markets.

[BENGALURU] Marathon Petroleum Corp agreed to buy rival Andeavor for more than US$23 billion in a deal creating one of the largest global refiners that will benefit from access to booming US shale fields and growing US fuel export markets.

The United States has become the world's top fuel exporter, shipping more than 3 million barrels per day (bpd) of gasoline and diesel. Refiners have capitalised on booming output from shale fields in Texas and North Dakota and are building out export terminals and processing facilities.

Buying Andeavor gives Marathon more exposure to the booming US shale oil sector, thanks to Andeavor's existing logistics and terminal operations in Texas and North Dakota shale regions. Rising output from the Permian Basin, the largest oilfield in the United States, has driven the nation's crude production to an all-time record above 10.5 million bpd.

"The combination of the two companies allows us to go after and find ways to create a bigger presence in the Permian," said Marathon chief executive Gary Heminger, who will lead the combined companies.

Market voices on:

The company would be able to process 3.1 million bpd of crude oil into gasoline, diesel and other fuels. That falls short of global giants Exxon Mobil Corp and China's Sinopec, but would be more than majors BP Plc and Royal Dutch Shell, and leapfrogs Valero Energy Corp to become the largest US refiner, according to company figures.

US motorists consume more fuel than any other country in the world and overall demand nationwide hit a record 9.3 million bpd in 2017.

Operations that have capacity to refine light crude produced in shale fields such as Andeavor, will be better positioned to take advantage of the production boom. Both North Dakota's Bakken and Texas shale regions primarily produce light, sweet crude oil.

The deal also gives Marathon a line into fast-growing Mexican fuel markets. Andeavor is expanding its network of filling stations in the country. Mexico's dilapidated refineries cannot meet the growing population's demand for gasoline and other products.

US fuel exports to Mexico rose to 1.4 million bpd as of January, up more than 85 per cent from two years ago.

The deal values Andeavor, formerly known as Tesoro, at about US$152 per share, or about 24 per cent more than Friday's closing price of US$122.38.

"We view this as pretty full value for Andeavor," Scotia Howard Weil analysts said in a note.

"Not many saw this one coming."


Shares of Ohio-based Marathon lost US$6.52, or 8 per cent, to close at US$74.91 a share. It also missed Wall Street forecasts for quarterly profit by a wide margin on Monday as expenses rose.

Shares of Andeavor, based in San Antonio, closed up 13 per cent at US$138.32.

Including Andeavor's debt, Marathon is paying US$35.6 billion to hold 66 per cent of a combined company worth some US$58 billion at Friday's close.

Andeavor operates 10 refineries in the United States, largely in the western part of the country. It has pipeline, trucking and terminal operations in the Permian and in the Bakken region, the second-most prolific state for oil production in the country after Texas.

"This creates one coast-to-coast, border-to-border refining and marketing company that seems well balanced with a pretty broad footprint," said Garfield Miller, CEO of Aegis Energy Advisors.

Marathon's six refineries are largely in the Midwest, with one located in Texas City, Texas. The Midwest region has reduced its reliance on crude oil from the Gulf Coast in recent years, pulling more of its barrels from Canada and North Dakota. Now, it is producing more products than it needs and has looked to export markets for additional opportunity.

Analysts at Tudor Pickering Holt said they expected the location of the two companies' operations to allow them to avoid antitrust hurdles.

Combining the companies' logistics subsidiaries will not happen immediately, Marathon CEO Gary Heminger said on a conference call following the transaction. He referred to that combination as a "day two issue".

Andeavor is expanding a retail network of motor fuel stations in the Mexican states of Baja California and Sonora under its Arco brand.

US Gulf Coast refiners are becoming more integrated in the region's energy industry, filling shortages created by underinvestment in refining across Latin America.

"There's no question the new company has greater resource capability going forward into Mexico," Andeavor CEO Gregory Goff said on a conference call with analysts.

The companies did not spell out Goff's role, but the Andeavor executive said he would likely be involved in operations and technology. Shares traded at about US$13 apiece when Mr Goff took the helm at Andeavor in 2010 and have risen nearly ten-fold in the past eight years.

The deal is expected to close in the second half of this year.
