NEW REVOLVING CREDIT FACILITY

Atrato Onsite Energy plc (LSE: ROOF), the investment company focusing on clean energy generation, is pleased to announce that it has arranged a £30.0 million Revolving Credit Facility ("RCF") with NatWest Bank.

The £30.0 million secured, interest only RCF has an initial three-year term and a one-year extension option at a margin of 1.30% over SONIA. The RCF also includes a £20.0 million uncommitted accordion option which is exercisable at any time over the initial term.

"This new Revolving Credit Facility will underpin the next stage of the Company's growth, providing the financial flexibility to capitalise on its significant pipeline of opportunities.

"The attractive margin of 1.30% reflects the Company's highly contracted income and low sensitivity to wholesale power prices."

"We are absolutely delighted to have been able to support Atrato Onsite Energy plc, one of the largest investors in commercial rooftop solar in the UK, with its first revolving credit facility.
