A line-up of US firms have taken roles on Caterpillar's $7.6bn (£4.7bn) acquisition of mining equipment manufacturer Bucyrus International, reports The Am Law Daily.

Mayer Brown advised Caterpillar on the the all-cash transaction – which, when including debt, is valued at $8.6bn (£5.4bn) – with a team led by Chicago M&A partners John Sagan and William Kucera.

Sidley Austin and Howrey also advised Caterpillar on the deal. Howrey vice-chair Sean Boland led an antitrust team including partners Paul Cuomo, Scott Hataway, Goetz Drauz and Stephen Mavroghenis, while at Sidley, corporate partner Paul Choi and banking and finance partner Michael Gold took the key roles.

James Buda, Caterpillar's general counsel, led an in-house legal team on the deal that included deputy GC Christopher Spears and senior corporate counsel Seth Prager.

The deal is expected to bolster Caterpillar's capacity in the mining equipment business, as Bucyrus specialises in the production of heavy-duty extraction equipment.

Bucyrus turned to Sullivan & Cromwell, which fielded a team led by M&A partners Scott Miller and Eric Krautheimer alongside tax partner David Spitzer and employee benefits partner Matthew Friestedt.

Bucyrus, a long-term client of the firm, was advised by Sullivan almost a year ago when it spent $1.3bn (£812m) to acquire the mining equipment subsidiaries of Terex Corporation.

Washington-based firm Arnold & Porter also took a role on the deal, serving as antitrust and competition counsel to Bucyrus.

Last month Mayer Brown advised Caterpillar on its €580m (£517m) acquisition of German engine maker MWM Holding, a deal which also handed roles to Clifford Chance and SJ Berwin.
