Atrato Onsite Energy plc

(the "Company")

Net Asset Value as at 31 March 2022

Atrato Onsite Energy plc (LSE: ROOF), the renewables investment trust focusing on UK commercial onsite solar and providing investors with capital growth and long-dated, index-linked income, announces its unaudited net asset value ("NAV") as at 31 March 2022.⁽¹⁾

Net Asset Value

The Company's NAV as at 31 March 2022 was £146.1 million (97.4 pence per Ordinary Share).

The NAV reflects the costs associated with the Company's Initial Public Offering ("IPO") and ongoing running costs, and incorporates the valuation of the Company's portfolio as at 31 March 2022.

Investment Update

On 23 November 2021, the Company's Ordinary Shares were admitted to trading following its IPO, which raised £150 million and was multiple times oversubscribed.

Since IPO, Atrato Partners Limited (the "Investment Adviser") has engaged with a growing pipeline of potential investment opportunities, which now totals over £390 million. The pipeline has not only increased in value, but the breadth of the customer base now reaches across many sectors in the UK and Ireland, including grocery, auto manufacturing, aerospace, and pharmaceuticals.

From its acquisition pipeline, the Investment Adviser has completed or is in advanced negotiations on eight investments totalling £24.3 million. The potential investment opportunities, which are predominantly greenfield, are expected to complete shortly. They are diversified by sub-sector and have a weighted average power purchase agreement length of over 21 years. These assets are expected to deliver a return in-line with the Company's targeted returns.

Macro-economic tailwinds in the renewables sector have proven even more favourable than expected at IPO. The combination of the current global inflationary environment together with the recent higher energy prices and increased volatility of energy markets has accelerated many corporate plans to roll out onsite green energy generation. These tailwinds are driving an acceleration of the broader corporate movement to de-carbonise energy production and have resulted in our own pipeline growing by a further 20% since IPO.

The Company re-iterates its expectation that the net proceeds of its IPO will be substantially invested or committed within 12 months of IPO.

Investment Adviser Update

Since IPO, the Investment Adviser has significantly bolstered the renewable energy team with 6 new senior level hires across its Investment Advisory and Finance functions. These individuals come with over 45 years in cumulative experience in the renewable energy sector.

Dividend

The Company continues to target an annualised dividend of five pence per Ordinary Share for the first and second financial years following admission to the premium listing segment of the Official List and to trading on the main market of the London Stock Exchange plc ("Initial Admission")⁽²⁾.

It is expected that the first quarterly dividend in respect of the period from Initial Admission to 31 March 2022 will be declared later this month and paid in May 2022.
