Although shares of Broadcom Ltd. experienced their biggest intraday trading drop ever after the newly redomiciled technology company announced Wednesday its $18.9 billion all-cash acquisition of CA Technologies, several large law firms have gained pay-day opportunities due to the proposed pairing.

Wachtell, Lipton, Rosen & Katz has landed the lead role for Broadcom, while Cleary Gottlieb Steen & Hamilton is serving as antitrust counsel to the San Jose, California-based semiconductor manufacturer. Cooley is also advising Broadcom, whose chief legal officer is Mark Brazeal, a longtime in-house lawyer who returned to the company in early 2017 after a stint as general counsel for SanDisk Corp.
