Statement regarding press speculation

Inmarsat plc notes recent press speculation regarding the intentions of Harbinger Capital Partners (“Harbinger”). The Company confirms it has received a very preliminary approach made on behalf of funds managed by Harbinger which may or may not lead to an offer being made for the Company. Discussions between the parties are at a very early stage and there can be no certainty that any offer will ultimately be made for Inmarsat or as to the terms of any such offer.

A further announcement will be made when appropriate

Relevant Securities in Issue

In accordance with Rule 2.10 of the City Code on Takeovers and Mergers the Company confirms that it has 458,400,172 Ordinary Shares of Euros 0.0005 each in issue and admitted to trading on the London Stock Exchange under the UK ISIN code GB00B09LSH68.

Dealing Disclosure Requirements:

Under the provisions of Rule 8.3 of the Takeover Code (the “Code”), if any person is, or becomes, “interested” (directly or indirectly) in 1% or more of any class of “relevant securities” of Inmarsat, all “dealings” in any “relevant securities” of that company (including by means of an option in respect of, or a derivative referenced to, any such “relevant securities”) must be publicly disclosed by no later than 3.30 pm (London time) on the London business day following the date of the relevant transaction. This requirement will continue until the date on which the offer becomes, or is declared, unconditional as to acceptances, lapses or is otherwise withdrawn or on which the “offer period” otherwise ends. If two or more persons act together pursuant to an agreement or understanding, whether formal or informal, to acquire an “interest” in “relevant securities” of Inmarsat, they will be deemed to be a single person for the purpose of Rule 8.3.

Under the provisions of Rule 8.1 of the Code, all “dealings” in “relevant securities” of Inmarsat by the potential offeror or Inmarsat, or by any of their respective “associates”, must be disclosed by no later than 12.00 noon (London time) on the London 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, and the number of such securities in issue, can be found on the Takeover Panel’s website at www.thetakeoverpanel.org.uk.

“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 Code, which can also be found on the Panel’s website. If you are in any doubt as to whether or not you are required to disclose a “dealing” under Rule 8, you should consult the Panel.

If you are in any doubt as to the application of Rule 8 to you, please contact an independent financial advisor authorised under the Financial Services and Markets Act 2000, consult the Panel’s website at www.thetakeoverpanel.org.uk or contact the Panel on telephone number +44 20 7638 0129; fax +44 20 7236 7013.
