Vinson & Elkins and Paul, Weiss, Rifkind, Wharton & Garrison are representing Houston-based Talos Energy LLC in its planned acquisition of Stone Energy Corp. in a deal that involves an all-stock combination valued at $1.9 billion.

Stone, based in Lafayette, Louisiana, turned to Akin Gump Strauss Hauer & Feld.

On Nov. 21, Talos and Stone announced that their boards of directors unanimously approved the merger that will link the offshore exploration and production companies. Terms of the transaction call for each outstanding share of Stone common stock to be exchanged for one share of Talos common stock, and current Talos shareholders will be issued about 34.2 million common shares, giving them a 63 percent stake in the company at closing. Based on Stone’s  stock price, the new company, to be known as Talos Energy Inc., will be valued at about $1.9 billion.

The combined company will be headquartered in Houston. Both companies have operations in the Gulf of Mexico.

The transaction is subject to approval from Stone shareholders, consent from the majority of Stone unaffiliated note holders, certain regulatory approvals and other customary closing conditions. The transaction is expected to close late in the first quarter of 2018 or early in the second quarter.
