A growing list of Facebook Inc.’s advertisers is set to halt spending on social media, undermining the company’s sales outlook and putting its stock price under further pressure.

Starbucks Corp., Levi Strauss & Co., PepsiCo Inc. and Diageo PLC were among the most recent companies to say they’re curtailing ad spending, part of an exodus aimed at pushing Facebook and its peers to suppress posts that glorify violence, divide and disinform the public, and promote racism and discrimination.

No single company can significantly dent growth at Facebook, which generated $17.7 billion in revenue last quarter alone. But a rising tally adds to pressure on other brands to follow suit, and when combined with a pandemic-fueled economic slowdown, the threat to Facebook deepens.
