Mayer Brown, a leading global law firm, served as lead deal counsel for Caterpillar Inc. on the acquisition of mining equipment firm Bucyrus International, Inc. for approximately $8.6 billion (including net debt).

The acquisition will expand Caterpillar’s leadership in the mining equipment industry and position the company to capitalize on the robust long-term outlook for commodities driven by the trend of rapid growth in emerging markets which are improving infrastructure, rapidly developing urban areas and industrializing their economies.

“Mayer Brown’s global reach and practice area depth, along with our established  track record in advising Caterpillar on numerous other deals, enabled us to provide the wide range of capabilities required for such a large transaction,” said Chicago Corporate & Securities partner John Sagan, who led the Mayer Brown team.  “Mayer Brown has represented Caterpillar on M&A matters since 2004.” 

Caterpillar will fund the acquisition through a combination of cash from the balance sheet, debt and up to $2 billion in equity. The transaction is expected to close in mid-2011.
