Abu Dhabi’s state-run investment firm Mubadala is injecting an undisclosed amount into UK-based fiber broadband provider Hyperoptic.

Following the deal, Mubadala, which has assets under management of $225 billion, will own a minority stake in the company and will place an observer on its board.

The investment from Mubadala follows Hyperoptic’s $329 million debt raise earlier in 2018, and will help enable the company to accelerate the growth of its fiber broadband network in the UK.

Founded in 2011, Hyperoptic plans to deploy up to about $658 million over the next three years as part of its efforts to reach 2 million homes by 2021. It originally planned to hit that target by 2022, but moved up its schedule by a year following its recent funding. The company already powers almost half a million homes and businesses in the UK.

Mubadala is investing “substantial capital” into Hyperoptic, according to Mounir Barakat, who serves as executive director of Mubadala ICT.

“We have been following Hyperoptic for the last couple of years and have been impressed by the impact they have had on the UK fibre market, taking a strong leadership, catalyst and disruptor role,” said Barakat, in a statement.

Mubadala has made a number moves in the ICT sector in the past, but prior to the Hyperoptic deal its portfolio was centered on companies in the UAE, including Al Yah Satellite Communications Company, Injazat Data Systems and the telecom du, among others.

The deal also comes a few months after Mubadala announced plans to create a $400 million fund to invest in European technology companies, with Japan’s SoftBank Group participating as a strategic investor.

The fund is intended to target investments in founder-led, high-growth technology companies that have global potential. It will also work closely with early-stage investors in the UK, as well as other European funds.
