Yankee Group sold to IT market specialists The 451 Group

M&A North America

US — Yankee Group, a research firm focused on the mobile communications market, has been sold by its private equity owners to The 451 Group, parent of IT market research specialists 451 Research and Uptime Institute.

Terry Waters, who has led Yankee Group since 2010, will remain CEO of the company but will now report to Martin McCarthy (pictured), chairman and CEO of The 451 Group.

McCarthy said: “For over four decades, the insights of Yankee Group have served the telecommunications industry and, more recently, the emergent mobility marketplace. Mobility is a huge driver of innovation in business and
technology markets globally. Its impact in the evolving enterprise and broader consumer IT marketplaces will
fundamentally shape the future expansion and strategy of digital infrastructure. With Yankee Group, we see an
exciting opportunity to significantly extend The 451 Group’s focus on the evolution of digital infrastructure.”

Yankee Group is headquartered in Boston and was founded in 1970. It has been owned by private equity firm Alta Communications since 2005 when Alta partnered with former Forrester executive Emily Nagle Green to buy Yankee Group from its then-owners Decision Matrix Group, who in turn had acquired it from Reuters 18 months before.

It was under Nagle Green that Yankee Group’s focus started to shift to mobile communications – under the banner of the Anywhere Revolution – following a new $10m investment from Alta in 2010. Later that year, Nagle Green became chairman and Waters became CEO.
