Posting of circular and notice of extraordinary general meeting

On 9 May 2014 3i Infrastructure plc ("3i Infrastructure" or "the Company") announced that it had entered into an agreement (the "Amendment Agreement") with 3i Investments plc (the "Adviser") to amend the terms of the existing investment advisory agreement between the Company and the Adviser (the "Advisory Agreement"), conditional only on obtaining the approval of both the Jersey Financial Services Commission and the Company's shareholders (other than 3i Group plc). The approval of the Jersey Financial Services Commission to the Amendment Agreement has now been obtained.

Today the Company posted a circular and notice of extraordinary general meeting ("EGM") to shareholders relating to the approval of the Amendment Agreement. This document has been made available on the Company's website (www.3i-infrastructure.com) and submitted to the National Storage Mechanism and will shortly be available for inspection at: www.morningstar.co.uk/uk/NSM

The EGM will be held at 16 Palace Street, London SW1E 5JD on Tuesday 8 July at 11.15am (or as soon thereafter as the annual general meeting of the Company scheduled for the same date has concluded).
