The transaction is expected to be finalised in six weeks' time, pending the conclusion of a TUPE consultation, which is likely to see around 30 of the Connect staff transferred to the Hertford-based business.
The deal will bring Intent's headcount to 90 and, with the Connect portfolio's 2010 sales of £5.4m, a combined revenue in excess of £10m for 2012, "essentially double the size of the company" according to Intent Media managing director Stuart Dinsey.
Alongside Music Week and its website and awards event, the portfolio also includes Television Broadcast Europe, Pro Sound News Europe and Installation Europe as well as websites, newsletters, conferences, show dailies and other events.
However, the future of the magazines is far from certain. Dinsey said the company had "a policy of investment in online and events" but that it would only "ensure longevity where possible for the core print titles".
"This is a significant move for Intent," he added. "We are heading into markets that fit our current landscape, whilst also continuing our policy of holding a leadership position wherever we operate."
The company publishes a range of titles including MCV, Develop, Toy News, Mobile Entertainment and Audio Professional International.
UBM Connect chief executive Adrian Barrack said: "On behalf of UBM I would like to thank all those working on these products for their contribution and to wish them well for the future".
