Atrato Onsite Energy plc

(the "Company")

Net Asset Value

Atrato Onsite Energy plc (LSE: ROOF), the investment company focusing on clean energy generation, announces its unaudited net asset value ("NAV") as at 30 September 2023.

Net Asset Value

The Company's NAV as at 30 September 2023 was £138.1 million or 92.0 pence per share (30 September 2022: £139.1 million or 92.8 pence per share).

In line with the higher interest rate environment, the Company valued its portfolio on a weighted average unlevered discount rate of 7.4% (30 September 2022: 6.6%, 31 March 2023: 6.2%). As at 30 September 2023 the Company did not have any debt and hence applies an unlevered discount rate to value its portfolio.

Summary of NAV key drivers:

Asset revaluation: Includes the value increase associated with projects progressing as they met specific key project milestones. The latter was predominantly driven by progress on Skeeby solar farm and Britvic's London Road project. This assume that all other variables are held equal.

Operational movements: Includes adjustments to individual assets for new contract pricing, the inclusion of REGOs in the valuation on projects where the Company benefits from REGOs and an update to the commercial operations date of installation projects where these have changed.

Net cash generated minus fund costs: Represents the net cash inflow of the Company's revenues less operating costs.

Inflation assumption: Reflects the impact of the updated inflation curves. The Company uses market forecast curves for CPI and RPI.

Power prices: Reflects the movement on the portfolio since September 2022 due to updated power price curves. The Company has one of the lowest sensitivities to power prices in the sector⁽¹⁾. Its high levels of contracted revenue limit its exposure to power price volatility and hence a 10% reduction in power prices would only have a 4.6% impact on the Company's NAV as at 30 September 2023.

Discount rate assumption: Represents the impact on the fair value from changes to the discount rate due to movements in interest rates, transactional prices observed in the sector and the macro-economic environment.

Dividends paid: Dividends of £7.5 million were paid during the year in respect of the period to 30 June 2023. The Company has a progressive dividend target from FY24 onwards and will announce its new target dividend as part of its FY 2023 results.

Outlook

The Company has grown rapidly over the year to become the leading commercial and industrial platform in the UK.  All the Company's remaining installation projects are expected to be energised by the end of March 2024 at which point the portfolio will be generating c.173GWh of clean energy, avoiding 37,000 tonnes of CO₂ emissions per annum. This is equivalent to powering 64,000 homes with clean energy.
