3i Infrastructure plc announces partial syndication of its investment in Attero

6 AUGUST 2018

3i Infrastructure plc ("3i Infrastructure" or "the Company") has signed an agreement to syndicate c.35% of its stake in Attero.

Attero is a European leader in waste treatment and processing in which 3i Infrastructure invested in June 2018. 3i Infrastructure's stake in the holding company for Attero will decrease from 50% to c.32.5%, in exchange for a c.€71 million consideration, representing a small premium to cost.

Following completion, 3i Investments plc, the Company's Investment Adviser, will retain governance of the entire 50% stake. 3i Infrastructure is considering syndicating a further tranche of c.15% of its original 50% stake in Attero in the coming months.

Richard Laing, Chairman of 3i Infrastructure plc, commented:

"It was always our intention to seek to sell down part of this investment, as part of our management of risk exposures within the portfolio. We are pleased with this outcome, which brings long term investors alongside us while preserving the governance position of our original 50% stake in Attero."

Phil White, Managing Partner and Head of Infrastructure, 3i Investments plc, commented:

"This transaction reduces the Company's exposure to power price risk and to the energy sector. Attero is a strong business, ideally placed to benefit from the positive dynamics in the European waste treatment sector, and led by a first class management team."
