(the "Company")

Net Asset Value

The Company announces that the unaudited net asset value as at 31 March 2022 on a cum-income basis was $122.1 million or $0. 9764 per ordinary share. The primary contributors to the $1.6m reduction in net asset value are:

· a $0.7 million decrease in net working capital at project level principally relating to budgeted seasonal fluctuations in operations at SED Solar Portfolio and Whirlwind and, therefore, in accounts receivable;

· a $0.4 million decrease due to an increase in the deferred tax accrual with $0.2 million arising from operations in the quarter and $0.2 million arising from a project level prior period adjustment;

· a $0.3 million decrease due to lower than forecasted production resulting from lower wind and solar levels at Whirlwind and SED Solar Portfolio during the quarter ended 31 March 2022;

with the balance of the reduction attributable to various smaller adjustments and the rolling forward of the discounted cash flow valuations.
