Aer Lingus Group plc

ISE: EIL1                    LSE: AERL

Possible Offer for Aer Lingus Group plc ("Aer Lingus" or the "Company")

The Board of Aer Lingus (the "Board") notes recent media speculation and the announcement by International Consolidated Airlines Group, S.A. ("IAG") that it is considering a possible offer for the Company. The Board confirms that on 14 December 2014 it received a preliminary, highly conditional and non-binding approach from IAG (the "Proposal").

The Board has reviewed the Proposal and believes that it fundamentally undervalues Aer Lingus and its attractive prospects. Accordingly, the Proposal was rejected on 16 December 2014.

This statement is being made by Aer Lingus without the prior agreement or approval of IAG. There can be no certainty that any offer will be made nor as to the terms of any offer. Shareholders are strongly advised to take no action.

Under the provisions of Rule 8.3 of the Irish Takeover Rules, if any person is, or becomes, "interested" (directly or indirectly) in 1% or more of any class of "relevant securities" of Aer Lingus or Blue, all "dealings" in any "relevant securities" of Aer Lingus or Blue (including by means of an option in respect of, or a derivative referenced to, any such "relevant securities") must be publicly disclosed by not later than 3:30 p.m. (Irish time) on the "business day" following the date of the relevant transaction. This requirement will continue until the date on which the Scheme becomes effective or on which the "offer period" otherwise ends. If two or more persons co-operate on the basis of any agreement either express or tacit, either oral or written, to acquire an "interest" in "relevant securities" of Aer Lingus or Blue, they will be deemed to be a single person for the purpose of Rule 8.3 of the Irish Takeover Rules. Under the provisions of Rule 8.1 of the Irish Takeover Rules, all "dealings" in "relevant securities" of Aer Lingus by Blue or "relevant securities" of Blue by Aer Lingus, or by any person "acting in concert" with either of them must also be disclosed by no later than 12 noon (Irish time) on the "business day" following the date of the relevant transaction.

A disclosure table, giving details of the companies in whose "relevant securities" "dealings" should be disclosed can be found on the Irish Takeover Panel's website at www.irishtakeoverpanel.ie. "Interests in securities" arise, in summary, when a person has long economic exposure, whether conditional or absolute, to changes in the price of securities. In particular, a person will be treated as having an "interest" by virtue of the ownership or control of securities, or by virtue of any option in respect of, or derivative referenced to, securities. Terms in quotation marks are defined in the Irish Takeover Rules, which can be found on the Irish Takeover Panel's website.
