According to the industry calculations discussed with Washington officials and lawmakers last week, U.S. President Trump's new tariffs could cost U.S. semiconductor equipment manufacturers more than $1 billion a year, according to two people familiar with the matter. The three largest chip equipment manufacturers in the United States - Applied Materials (AMAT.O), Panlin Group (LRXC.O) and KLAC.O) may suffer about $350 million in losses due to tariffs within one year. And smaller competitors like Onto Innovation may also face additional spending in tens of millions of dollars.
