nfNext Fifteen Communications Group, citing strong growth, particularly in the US, said it will sell more than three million shares to raise £4.3M ($6.5M) for digital acquisitions and investments in the US and UK.

The UK-based parent to firms like Text 100, M Booth, The Blueshirt Group and Bite, said three "specific smaller investment and acquisition opportunities" are expected to close in the next six months.

CEO Tim Dyson Next Fifteen's US operations have show strong trading with double-digit organic revenue growth.

"The acquisitions we have in mind will continue Next 15’s overall drive to create a new type of integrated marketing group which has at its core the technology of marketing: content, data, insight, analytics, apps and content platforms," he said.

NF acquired content ad agency Story Worldwide for $6.6M in October.
