Court confirmation of Reduction of Capital

Fiberweb and PGI Acquisition are pleased to announce that the High Court of Justice in England and Wales has today made an order confirming the reduction of share capital of Fiberweb by the Scheme Shares in connection with the Scheme by which the acquisition of Fiberweb by PGI Acquisition is being implemented. This follows the Court’s sanction of the Scheme at a hearing held on 13 November 2013.

With effect from 5:00 p.m. on 14 November 2013, Fiberweb Shares were temporarily suspended from the Official List and the London Stock Exchange’s main market for listed securities. The listing on the Official List and the admission to trading on the London Stock Exchange’s main market for listed securities of Fiberweb Shares are expected to be cancelled by 8.00 a.m. on 18 November 2013.

All of the conditions set out in the Scheme Document published on 30 September 2013 have now been satisfied, other than the delivery to the Registrar of Companies of a copy of the Reduction Court Order and the associated Statement of Capital, at which point the Scheme will become effective.

It is anticipated that the Scheme will become effective later today. Further details of the expected timetable of principal events are set out below.

Capitalised terms, unless otherwise defined in this announcement, have the meanings given to them in the Scheme Document published on 30 September 2013.

Disclosure requirements of the Code

Under Rule 8.3(a) of the Code, any person who is interested (directly or indirectly) in 1% or more of any class of relevant securities of any party to the offer (other than a cash offeror) must make an Opening Position Disclosure after the commencement of the offer period and, if later, after the announcement that first identifies any offeror (other than a cash offeror). An Opening Position Disclosure must contain details of the person’s interests and short positions in, and rights to subscribe for, any relevant securities of any party to the offer (other than a cash offeror). An Opening Position Disclosure by a person to whom Rule 8.3(a) applies must be made by no later than 3.30 pm (London time) on the day falling 10 business days after the commencement of the offer period or the announcement that first identifies an offeror (as the case may be). Relevant persons who deal in the relevant securities of any party to the offer (other than a cash offeror) prior to the deadline for making an Opening Position Disclosure must instead make a Dealing Disclosure.

Under Rule 8.3(b) of the Code, any person who is (or as a result of any dealing becomes) interested (directly or indirectly) in 1% or more of any class of relevant securities of any party to the offer (other than a cash offeror) must make a Dealing Disclosure if the person deals in any relevant securities of any party to the offer (other than a cash offeror) during an offer period. A Dealing Disclosure must contain details of the dealing concerned and of the person’s interests and short positions in, and rights to subscribe for, any relevant securities of any party to the offer (other than a cash offeror), save to the extent that these details have previously been disclosed under Rule 8. A Dealing Disclosure by a person to whom Rule 8.3(b) applies must be made by no later than 3.30 pm (London time) on the business day following the date of the relevant dealing.

Where two or more persons act pursuant to an agreement or understanding, whether formal or informal, to acquire or control an interest in relevant securities, they will normally be deemed to be a single person for the purpose of Rule 8.3.

Opening Position Disclosures must also be made by the offeree company and by any offeror and Dealing Disclosures must also be made by the offeree company, by any offeror and by any persons acting in concert with any of them (see Rules 8.1, 8.2 and 8.4).

Details of the offeree and offeror companies in respect of whose relevant securities Opening Position Disclosures and Dealing Disclosures must be made can be found in the Disclosure Table on the Takeover Panel’s website at www.thetakeoverpanel.org.uk, including details of the number of relevant securities in issue, when the offer period commenced and when any offeror was first identified. You should contact the Panel’s Market Surveillance Unit on +44 (0)20 7638 0129 if you are in any doubt as to whether you are required to make an Opening Position Disclosure or a Dealing Disclosure.
