About WIG

Following its launch in 2006, WIG has invested in over 2,000 assets including communications towers and other wireless infrastructure across the UK. WIG's higher capacity infrastructure enables industry leading levels of mobile and other wireless connectivity.

The Company has an active investment programme covering:

· new towers in rural areas (where over 50% of WIG's investments have been made to date);

· new infrastructure to enable better connectivity across the UK's major road and rail routes; and

· small cells to improve mobile coverage in buildings and on city streets.

WIG is the UK market leader for the deployment of neutral host DAS networks needed to deliver mobile signal to large public venues and is growing its fibre investments to support the deployment of outdoor small cells.

WIG is also targeting the acquisition and upgrade of communication towers owned by UK mobile operators. Over 60% of communication towers globally and over 80% in the US are now independently operated. Only one third of UK towers are independently operated and increasing the role of independent infrastructure can play a vital part in improving mobile connectivity.
