AI Data Center Leader Loses 11 Trillion Won in a Day Despite Strong Performance

Eaton Corporation plc (ETN) saw its share price tumble 5.9% on the New York Stock Exchange on the 10th, closing at $376.88 and erasing roughly $8.1 billion (about ₩11 trillion) in market value in a single day.

Trading volume exceeded 1.81 million shares, and despite the sell-off, Eaton still boasts a market capitalization of about $146.3 billion (roughly ₩205 trillion), firmly anchoring it in the large-cap tier.

In its first-quarter results released last month, Eaton reported record revenue of $7.45 billion and earnings per share of $2.22, and subsequently raised its 2026 organic sales-growth guidance from 8% to 10%.

However, with expectations for growth in its AI data-center and aerospace segments largely priced in, analysts note that investors have refocused on near-term margin pressures and high valuation multiples, driving today’s mid-single-digit decline of over 5%.

Headquartered in Ireland, Eaton Corporation is a global intelligent power-management company supplying power infrastructure and distribution equipment, data-center power solutions, and aerospace systems worldwide.

The company is leveraging U.S. and European firms’ expanding investments in AI data centers and broader electrification trends as key growth drivers. It has also been aggressively expanding its data-center infrastructure portfolio through roughly $11 billion of acquisitions—most notably the purchase of Boyd Thermal—to bolster its cooling and thermal-management capabilities.
