Warren Buffett's near 20 per cent stake in Occidental Petroleum has some investors expecting the billionaire to eventually absorb the oil producer and turn it into a "cash machine" that feeds his other investments.
Mr Buffett's Berkshire Hathaway has been snapping up Occidental shares since 2019, when it bought around $10 billion in preferred stock to help the company finance a deal for a rival. That investment came with warrants for 83.9 million shares.
Mr Buffett, who told shareholders earlier this year that cash is like oxygen, is likely attracted by estimates showing Occidental's cash flow potential has soared, analysts said. He added 4.3 million this week bringing direct holdings to 179.4 million. The stock is up about 80 per cent so far this year.
Berkshire declined to comment on the share purchases.
Occidental has recovered from the near-death experience of loading up on debt to buy Anadarko Petroleum for $35.7bn just before Covid-19 pandemic cratered oil demand. An oil recovery has accelerated debt repayments and sliced its interest costs.
Once Mr Buffett crosses 20 per cent ownership, he could book a fifth of Occidental's profit through its Berkshire Energy subsidiary. Or he could keep going and buy the firm for its cash flow. Occidental's cash flow will hit $19.36bn this year from $3.84bn two years ago, according to Refinitiv.
Some investors think Mr Buffett will follow the same script he did with Burlington Northern Santa Fe. Berkshire started accumulating BNSF shares in 2006 and took it all four years later.
Berkshire held $106.3bn in cash at the end of March.
"Holding cash is a low return undertaking," said oil analyst Paul Sankey, who thinks Mr Buffett has plans for that money.
"A debt-free Oxy would be a cash machine of the kind Buffett favours," he said.
A buyout could free up more than $2bn in this year's interest expense and administrative costs, estimates Neal Dingmann of Truist Securities. He appraises the chance of a Mr Buffett deal as good.
"It's almost like an annuity. It's a great offset for his rail and other businesses," Mr Dingmann added, referring to BNSF.
A deal would lessen Occidental's exposure to investor calls to shift from fossil fuels to renewables or to restrain growth in favour of returns. Harold Hamm recently offered to take private Continental Resources, the US oil company he founded, at a $25bn valuation.
"The opportunity today is with private companies who have the freedom to operate and are not limited by public markets," Mr Hamm said of his offer.
Truist's Mr Dingmann sees Occidental's Low Carbon Ventures as a potential upside if Washington funds projects that reduce emissions or increases tax credits for carbon-capture projects.
Not everyone agrees Mr Buffett wants a company in a cyclical industry.
"The energy companies Berkshire owns are all regulated with relatively low business risk," said Carol Levenson, an analyst with bond research firm Gimme Credit.
Taking Occidental private does not fit Berkshire's practice of avoiding boom-bust industries, and would face resistance from Occidental, she said.
"I don’t believe Oxy would go quietly, having demonstrated a desire to remain independent," she added.
