Offshore Drilling Stocks Surge Over 1 Trillion Won in Market Capitalization in One Day Due to Earnings Surprise

Noble Corporation plc (NYSE: NE), an offshore drilling company, surged 8.63% in today’s trading session on the New York Stock Exchange, closing at $53.82 with approximately 1.66 million shares traded. Its market capitalization climbed to about $8.6 billion (₩11.6 trillion), adding roughly $800 million (₩1.1 trillion) in a single day.

On April 26, Noble announced first-quarter 2026 results, reporting revenue of $780 million and net income of $121 million—a 12% year-over-year gain in profit that beat market expectations. The company’s backlog expanded to around $7.5 billion (approximately ₩10 trillion). While maintaining its full-year guidance, Noble enhanced its revenue visibility by securing new drilling contracts worth about $1.3 billion in January, including awards in the Norwegian offshore market.

Headquartered in the U.K., Noble is a global offshore drilling specialist. Following its 2021 merger with Maersk Drilling and its 2024 acquisition of Diamond Offshore Drilling, the company has been reshaped into a major offshore driller. Serving large international oil companies, Noble operates advanced deepwater drillships and semisubmersible rigs, positioning it to benefit from rising oil prices and offshore drilling investment cycles.
