Finsbury is handling Advent International's $5B bid for Cobham, UK defense & aerospace company, a deal that is expected to go under tough scrutiny by British regulators and politicos.

Silchester International, Cobham's biggest investor, opposes the takeover because it believes the supplier of gear to Boeing, Lockheed Martin, and Airbus could fetch a higher price after it completes its turnaround strategy and cleans up its balance sheet.

David Lockwood, CEO of Cobham, said partnering with the Boston-based private equity firm will provide the investment the company needs to further "leverage the quality of our products and services."

Advent's 165 pence per-share offer represents a 34 percent premium over the pre-announcement closing price.

Finsbury's James Murgatroyd, Dorothy Burwell and Humza Vanderman represent Advent.

Cobham relies on MHP Communications (Reg Hoare, Tim Rowntree and Nessyah Hart).
