This week, a pair of $48 billion deals, along with their legal teams, reign supreme.

Reports surfaced Wednesday that a health insurance megamerger is imminent between Indianapolis-based Anthem and Bloomfield, Connecticut-based Cigna, with the former seeking to acquire the latter in a $48 billion cash-and-stock deal.

The insurance industry has been particularly busy consolidating of late, with The Am Law Daily noting earlier this month the half-dozen firms handling Aetna’s $37 billion acquisition of Humana, a deal that took place immediately following the U.S. Supreme Court’s latest rejection of a challenge to the Affordable Care Act.

White & Case and veteran M&A partner Daniel Dufner Jr.—a former Am Law Daily Dealmaker of the Week for his work advising WellPoint on its $4.9 billion acquisition of rival health insurer Amerigroup in 2012—has picked up the lead role advising Anthem. (Anthem used to be called WellPoint, having adopted its current name last year.)

Cigna, the target, has turned to Cravath, Swaine & Moore for lead counsel on the potential deal. Cadwalader, Wickersham & Taft is advising Cigna on antitrust matters, while Sidley Austin is serving as health care regulatory counsel to the company. Latham & Watkins is representing the lead arrangers providing financing for the proposed combination.

On Tuesday, in another megadeal at a different stage of completion, the U.S. Department of Justice announced it would not challenge AT&T’s $48 billion purchase of satellite television operator DirecTV. The Federal Communications Commission is also expected to give its go-ahead to the transaction, which as noted by The Am Law Daily yielded roles for a dozen firms when it was announced in May 2014.

Intense antitrust scrutiny foiled AT&T’s previous bid to buy T-Mobile USA for $39 billion in 2011, a tie-up the former abandoned in December of that year in the face of Justice Department opposition. The busted deal saw AT&T pay a $4 billion breakup fee and raised questions about when deals go bad; how much blame do the legal advisers receive? In AT&T’s case, it appears the telecom giant didn’t hold a grudge.

The Litigation Daily, a sibling publication, reported this week that AT&T’s legal team on the T-Mobile deal—Sullivan & Cromwell, Arnold & Porter, Crowell & Moring, Sidley and Washington, D.C.–based Kellogg, Huber, Hansen, Todd, Evans & Figel—got the call for the DirecTV transaction.
