Carl Icahn increased his stake in Occidental Petroleum from 2.5% to nearly 10%.

Why it matters: Icahn has been feuding with Occidental since last summer, believing his $38 billion takeover of Anadarko Petroleum was too expensive and poorly structured.

  • Now he's taking advantage of macro conditions (coronavirus, Saudi-Russia deal collapse, etc.) to strengthen his hand, as Occidental's market cap has fallen to $10.5 billion and it just slashed its dividend for the first time in 30 years.

Icahn wants control, which would include a new CEO and a new board of directors.

  • The bottom line: "Many shale producers including Occidental were struggling to turn a profit even before the coronavirus and tension among big oil-producing states sent crude prices down sharply. Occidental is particularly vulnerable given its high debt level — roughly $40 billion at last count," writes the Wall Street Journal.

Firefighters in the western U.S. were facing "critical fire weather conditions," as a rapidly spreading new wildfire in Northern California prompted fresh evacuations Sunday.

Why it matters: Wildfires have burned a record 3.6 million acres in California this year, killing 26 people and razing over 7,600 structures, per Cal Fire. Utility provider Pacific Gas & Electric cut power to 11,000 customers early Sunday and planned outages for 54,000 others later in the day because of fire risks.
