BREAKING: Transocean Just Swallowed Valaris — The Offshore Drilling Monster Is Born

$5.8 billion. 73 rigs. One company. Everything you need to know — and what happens next.

This is a boom that came out of nowhere.

This morning, Transocean (RIG) announced a definitive agreement to acquire Valaris (VAL) in an all-stock transaction valued at approximately $5.8 billion. The deal was unanimously approved by both boards of directors and is expected to close in the second half of 2026.

This is the biggest offshore drilling M&A deal in years — and it changes everything about how you should think about these stocks.

Let’s break it down.

Here’s the important part for Valaris shareholders: you are not getting cashed out. You are becoming shareholders of the largest offshore drilling company on the planet. The combined entity will have a pro forma market capitalization of approximately $12.3 billion. That’s solidly mid-cap territory — big enough to attract institutional flows that neither company could attract on its own.

If you were holding VAL because you believed in the offshore upcycle, congratulations — you just got upgraded to the best seat in the house.

But what does all of this actually mean for Transocean shareholders?
