Occidental Petroleum Corp. cut its quarterly dividend by 91% to the lowest since at least the 1970s amid the pandemic-driven collapse in energy demand that has strained the oil explorer’s ability to shoulder its debt. Occidental shareholders will receive a penny per share on July 15, the Houston-based company said in a statement Friday. The move extends a cut announced in March when it trimmed the payout to 11 cents from 79 cents.

The surprise cut came the same day under-fire Chief Executive Vicki Hollub and the rest of the board of directors won re-election at Occidental’s annual shareholders’ meeting. The company will announce the final vote tallies in a regulatory filing later.

Hollub has weathered extreme pressure from shareholders ever since outbidding Chevron Corp. to win the purchase of Anadarko Petroleum Corp. last year. The deal saddled Occidental with some $40 billion of debt that was looking hard to pay off even before Covid-19 wiped out global oil demand, sending crude prices plunging to an unprecedented minus $40 a barrel at one point last month.
