AI Data Center Beneficiary Eton: Reasons for $12 Billion Loss in a Day

Eaton Corporation plc (NYSE: ETN) plunged 6.26% on the New York Stock Exchange on the 5th, closing at $392.39 (approximately KRW 540,000). With trading volume exceeding 1.35 million shares, the company shed about $9 billion (roughly KRW 12 trillion) in market value in a single day, bringing its market capitalization down to around $152.3 billion (about KRW 210 trillion). A broad pullback across the industry and profit-taking drove Eaton’s decline deeper than the overall industrials sector, despite no specific negative news from the company.

Just one month earlier, Eaton reported first-quarter 2026 sales of $7.4 billion and adjusted EPS of $2.81, surpassing analyst expectations. It also raised its full-year organic growth guidance and completed approximately $11 billion in acquisitions, including Boyd Thermal. More recently, Bernstein and Bank of America raised their price targets to $509 and $490, respectively, and maintained buy ratings based on anticipated increases in power demand from AI data centers.

Headquartered in Dublin, Ireland, Eaton is a global power-management company that supplies electrical distribution equipment, UPS systems, data-center power infrastructure, aerospace solutions, and industrial automation. As energy transition initiatives and AI-driven data-center investments accelerate in North America and Europe—where Eaton is seen as a leading provider of power infrastructure—investors are closely watching to determine whether this sharp sell-off marks a trend reversal or is merely a temporary correction.
