FGS Global and Joele Frank are working Advent International’s $6.4B takeover of Maxar Technologies, Westminster, CO-based satellite manufacturer/operator and space-based imagery company.

Boston’s Advent, which has $89B in assets under management, is offering $53 per share for Maxar’s stock, a 129 percent premium. The equity firm is a major investor in the defense, security and cybersecurity sectors.

As a private company, Maxar believes it will benefit from Advent’s financial resources, operational expertise and capacity for investment.

“Maxar’s mission has never been more important, and this transaction allows us to maximize value for stockholders while accelerating the company’s ability to deliver its mission-critical technology and solutions to customers over the near and long-term,” said Maxar chair General Howell Estes, who served in the Air Force.

FGS Global’s Bryan Locke and Jeremy Pelofsky represent Advent.

Joele Frank, Wilkinson Brimmer Katcher’s Scott Bisang, Eric Brielmann and Jack Kelleher handle Maxar.
