The announcement stated that H.B. Fuller was required, by no later than 5.00 p.m. (London time) on 18 June 2026 (the "PUSU Deadline"), to either announce a firm intention to make an offer for AMS in accordance with Rule 2.7 of the Code or 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.

Discussions between the parties remain ongoing. Accordingly, the Board of AMS has requested and the Panel on Takeovers and Mergers (the "Takeover Panel") have consented to an extension of the PUSU Deadline.

This deadline can be extended with the consent of the Takeover Panel, in accordance with Rule 2.6(c) of the Code.

There can be no certainty that an offer will be made, nor as to the terms at which a firm offer might be made.

A further announcement will be made when appropriate. In the meantime, the Board of AMS advises shareholders to take no action.
