Discussions with Sidara remain ongoing. In accordance with Rule 2.6(c) of the Code, the Board has requested and the Takeover Panel has consented to an extension to the date by which Sidara is required either to announce a firm intention to make an offer for Wood in accordance with Rule 2.7 of the Code or to announce that it does not intend to make an offer, in which case the announcement will be treated as a statement to which Rule 2.8 of the Code applies. Such announcement must now be made by not later than 5.00pm on 9 August 2024. This deadline can be further extended by the Board of Wood, with the consent of the Takeover Panel.

There can be no certainty that an offer will be made. Further announcements will be made as appropriate.

Under Rule 8.3(b) of the Code, any person who is, or becomes, interested in 1% or more of any class of relevant securities of the offeree company or of any securities exchange offeror must make a Dealing Disclosure if the person deals in any relevant securities of the offeree company or of any securities exchange offeror.

If two or more persons act together pursuant to an agreement or understanding, whether formal or informal, to acquire or control an interest in relevant securities of an offeree company or a securities exchange offeror, they will 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)
