MKS Inc. (NASDAQ: MKSI), a U.S.-based semiconductor equipment company, closed at $317 on the Nasdaq, up 5.39%, with a trading volume of about 1.27 million shares. Its market capitalization climbed to roughly $21.3 billion—an increase of about $1.2 billion in a single day (approximately KRW 1.7 trillion)—bringing its total valuation to around KRW 29.9 trillion.

The company reported first-quarter revenue of $1.078 billion and net income of $84 million, meeting the top end of its guidance. Analysts attribute the beat to strong AI-related demand. Alongside the earnings release, MKS carried out a large-scale debt restructuring, and both JPMorgan and Citigroup raised their price targets to $365 and $355, respectively, signaling further upside potential.
