Companies including Tyson Foods Inc. and JBS SA, which control a sizable chunk of global meat supplies, are set to report a spike in earnings for the quarter ended in June as a rebound in poultry profits counterbalances a downturn in their US beef operations.

JBS USA said it paid $11 million in ransom to criminals responsible for the cyberattack that disrupted meat processing across North America and Australia, the latest high profile example of large corporations falling prey to extortion.

A cyberattack on JBS SA, the world’s largest meat producer, has forced the shutdown of some of the largest slaughterhouses globally, and there are signs that the closures are spreading.
