Net Asset Value and Dividend Declaration

16 August 2018

JOHN LAING ENVIRONMENTAL ASSETS GROUP LIMITED

("JLEN" or the "Company")

Net Asset Value and Dividend announcement

NAV

JLEN, the listed environmental infrastructure fund, announces its unaudited Net Asset Value ("NAV") as at 30 June 2018 and interim dividend for the quarter ended on that date.

The Company's unaudited NAV as at 30 June 2018 was £392.3 million or 99.6 pence per share, compared to £392.4 million or 99.6 pence per share as at 31 March 2018.

Portfolio update

For the quarter to 30 June 2018, generation for the solar portfolio was in line with budget and the anaerobic digestion ("AD") portfolio continued the positive trend observed previously, being materially up for the same period.

The wind portfolio was below budget reflecting poor wind resource, in line with observations from other wind asset owners. In aggregate, the renewables portfolio saw generation just below budget but benefited from higher than forecast gas and electricity prices for those plants not on fixed price arrangements. Waste and wastewater assets continue to perform in-line with expectations.

JLEN has continued to diversify its portfolio since June, having acquired three AD projects including the Merlin plant announced today, which has seen the company draw down finance from its revolving credit facility. JLEN continues to evaluate an attractive pipeline of opportunities in the environmental infrastructure sector and accordingly, intends to seek new equity capital in the coming months to fund acquisitions which deliver long-term predictable cash flows and are supported by long term contracts or stable and well-proven regulatory and legal frameworks.

Dividend

The Company announces a quarterly interim dividend of 1.6275 pence per share for the quarter ended 30 June 2018, in line with the dividend target of 6.51p per share for the year to 31 March 2019, as set out in the 2018 Annual Report.
