At AK Steel, President Trump’s tariffs on metals imports boosted prices this spring even more than Chief Executive Officer Roger Newport predicted.

The West Chester, Ohio-based company said Monday that it was able to charge $1,101 per ton of flat-rolled steel in the three months through June, a 5 percent increase from the beginning of 2018. Newport, who has praised the White House’s move to protect the U.S. steel industry, had told investors in April that prices would rise to at least $1,075 per ton.
