From AI Data Center Beneficiary to Plummeting Stock: 2 Trillion Won Vanished in a Day

US technology stock TTM Technologies Inc. (NASDAQ: TTMI) closed at $191.20 on the 26th, down 9.2% from the previous day. Trading volume exceeded 16.09 million shares, and its market capitalization fell to about $19.9 billion (roughly ₩28 trillion), erasing approximately $1.67 billion (₩2.3 trillion) in value in a single session.

On June 17, the company announced acquisitions of Swiss-based Swiss Technology Group AG and Germany’s ILFA GmbH to broaden its European PCB and high-frequency components production capacity. The previous day, IT Senior Vice President Dale Knecht reportedly sold around $1.4 million worth of shares, adding pressure to investor sentiment.

TTM Technologies is a global manufacturer of advanced printed circuit boards, RF components and mission systems, with significant revenue exposure in data centers, AI servers and the aerospace and defense sectors. In the first quarter of this year, it posted record quarterly sales of $846 million, a 30% increase year-over-year, leading the market to debate whether the recent pullback is a buying opportunity or a critical inflection point.
