Lapse of Antwerp Management Limited's Offer for Augean Plc

On 23 September 2021, pursuant to the auction process established by the Panel on Takeovers and Mergers (the "Panel"), Antwerp Management Limited ("MSIP Bidco"), a newly-formed company indirectly owned by funds managed or advised by Morgan Stanley Infrastructure Inc., an indirect subsidiary of Morgan Stanley, announced the terms of an increased cash offer for the entire issued and to be issued ordinary share capital of Augean Plc ("Augean" or the "Company") at a price of 361 pence for each Augean Share (the "MSIP Auction Offer").

On the same date, Eleia Limited ("Eleia Bidco"), a newly formed company indirectly owned by a consortium consisting of investment funds managed by (i) Ancala Partners LLP, and (ii) Fiera Infrastructure Inc., announced the terms of a higher increased cash offer for the entire issued and to be issued share capital of Augean at a price of 372 pence for each Augean Share (the "Increased Eleia Offer").

The Increased Eleia Offer has been recommended by the board of Augean. In light of the Augean Directors' recommendation of the Eleia Increased Offer, the Augean Directors have withdrawn their recommendation of the MSIP Auction Offer and have adjourned the MSIP Shareholder Meetings (comprising the Court Meeting and the General Meeting) until further notice.

The Scheme was conditional on the MSIP Shareholder Meetings being held on or before the 22^nd day after the expected date of the MSIP Shareholder Meetings (being 1 October 2021). As of the end of 1 October 2021, conditions 2(a)(ii) and 2(b)(ii), as set out in the Scheme Document, have not been satisfied. This announcement confirms that the MSIP Auction Offer has now lapsed.

Capitalised terms in this announcement, unless otherwise defined, have the same meanings as set out in the Scheme Document published by MSIP Bidco on 16 August 2021.

White & Case LLP has been retained as legal adviser to MSIP and MSIP Bidco.
