Gartner and Meta, two major analyst firms for the IT industry, have agreed to merge in a $162m (£86m) deal.
The resulting company will be a formidable IT research and consulting firm, likely to benefit end user organisations through its broad range of consulting services, said Gartner.
Gene Hall, Gartner's chief executive officer, said, "This transaction is an exciting opportunity that will give us increased depth in key sectors, geographies and markets, and an increased ability to seize revenue opportunities with the addition of Meta Group's well-trained, successful sales force.
In sum, the acquisition will make Gartner a stronger company with increased opportunities for growth and greater resources to offer clients."
Gartner made its bid to acquire Meta Group at the end of December, in an all-cash transaction.
In 2003, Gartner generated $858m in revenue from 76 locations around the world, while Meta Group generated $122m in revenue from 52 locations.
