CityFibre agrees Master Services Agreement with Level 3

First call off in Edinburgh under new agreement

CityFibre (AIM: CITY), a leading designer, builder, owner, and operator of fibre optic infrastructure in UK towns and cities, is pleased to announce the signing of a national Master Services Agreement ('MSA') with international network, voice and data services provider, Level 3 Communications Limited ('Level 3'). The Company also announces today the first call off under the MSA, across the Group's Edinburgh network.

The MSA sets out standard terms and pricing under which Level 3 can procure fibre from CityFibre's expanded network to service its numerous enterprise customers across the UK.

The first call-off under the MSA is a dark fibre metro ring on CityFibre's Edinburgh network, to which Level 3 will connect local customer sites.

Greg Mesch, Chief Executive of CityFibre, commented:

"We are delighted to be able to announce both the MSA and the first commercial call-off in Edinburgh with Level 3. This marks an innovative solution for CityFibre customers, in providing both a resilient dark fibre metro ring as well as additional connections to customer locations.

"This agreement demonstrates the enhanced relevance our UK footprint now has to international service providers providing solutions to the UK market. Clearly, with our expanded presence in 37 towns and cities across the UK, we offer increased scope for Level 3 to migrate customers to on-net dark fibre connections with significant advantages in terms of cost and solution architecture."
