From the article:

"Four companies - Tyson, JBS, Cargill and National Beef - control around 85% of American beef processing.

That high level of market concentration has drawn accusations of price-fixing, even from President Trump.

So you might expect that those four firms are currently making huge profits from high beef prices. Yet the opposite is happening.

Tyson, the biggest of the four, reported in May that it had lost more than $500m on beef in the first half of its financial year."
