US Offshore Driller Sees Market Cap Surge of $4 Billion in One Day Following $5.8 Billion Mega Deal

Valaris Ltd (NYSE: VAL) closed at $83.82, surging 34.29% on the New York Stock Exchange. Trading volume jumped to roughly 8.2 million shares, and the company’s market capitalization climbed by about $3 billion in a single day to reach $5.8 billion.

The sharp rise followed Swiss oil-services firm Transocean’s announcement that it will acquire Valaris in an all-stock merger valued at approximately $5.8 billion. The combined company will operate 73 offshore drilling units with a backlog of nearly $10 billion, positioning it as a global offshore-drilling powerhouse. Valaris shareholders are set to receive roughly 47% of the new company’s equity.

Valaris is a leading offshore-drilling contractor with a fleet that includes deepwater drillships, semisubmersibles and shallow-water jackup rigs. The company took its current name in 2019 after the merger of Ensco and Rowan. In response to the 2020 oil-price collapse, Valaris filed for Chapter 11 bankruptcy in the United States, restructuring about $7.1 billion of debt in 2021. Since emerging from bankruptcy, its financial performance and share price have rebounded in line with the offshore-drilling market recovery.
