U.S. semiconductor equipment makers could face over $1 billion in annual losses from President Donald Trump's new tariffs, according to Yahoo Finance. Applied Materials, Lam Research, and KLA may each see around $350 million in lost revenue and higher costs. At the same time, smaller players like Onto Innovation anticipate tens of millions in added expenses. The estimates include lost overseas sales, supplier shifts, and compliance burdens. The tariffs follow years of export controls under the Biden administration and come amid Trump’s efforts to increase domestic chip manufacturing.
