FOR IMMEDIATE RELEASE

2 July 2026

RECOMMENDED CASH ACQUISITION

of

Treatt PLC ("Treatt")

by

DÖHLER FINANCE MANAGEMENT B.V. ("Döhler")
(a private limited liability company incorporated in the Netherlands with registered number 69165009, an indirect wholly-owned subsidiary of Döhler Group SE)

effected by means of a Court-sanctioned scheme of arrangement
under Part 26 of the Companies Act 2006

Scheme of Arrangement becomes Effective

On 29 April 2026, the boards of Treatt and Döhler announced that they had reached agreement on the terms of a recommended cash offer by Döhler for the entire issued and to be issued share capital of Treatt not already owned by Döhler at a price of 305 pence per Treatt Share (the "Acquisition").

In addition, the Acquisition allowed for the distribution of the previously announced final dividend for the year ended 30 September 2025 of 3 pence per Treatt Share paid on 13 May 2026 to Treatt Shareholders on the register as at the close of business on 7 April 2026.

The Acquisition is being effected by means of a Court-sanctioned scheme of arrangement under Part 26 of the Companies Act 2006 (the "Scheme"). The scheme document in relation to the Scheme was published on 12 May 2026 (the "Scheme Document").

On 30 June 2026 Treatt and Döhler announced that the Court had issued the Court Order sanctioning the Scheme pursuant to which the Acquisition will be implemented.

Treatt and Döhler are pleased to announce that, following the delivery of a copy of the Court Order (together with a copy of the Scheme and all documents required annexed thereto) to the Registrar of Companies today, the Scheme has now become Effective in accordance with its terms. Pursuant to the Scheme, the entire issued share capital of Treatt is now owned by Döhler.

Suspension and cancellation of listing to and trading of Treatt Shares

The listing of Treatt Shares on the Official List and admission to trading on the Main Market, and therefore dealings in Treatt Shares on the Main Market, will be suspended with effect from 7:30 a.m. today. As a result of the Scheme having become Effective, share certificates in respect of the Scheme Shares have ceased to be valid documents of title and entitlements to the Scheme Shares held in uncertificated form in CREST are being cancelled.

Applications have been made to the Financial Conduct Authority and the London Stock Exchange in relation to the cancellation of the listing of Treatt Shares on the Official List and the cancellation of admission to trading of Treatt Shares on the Main Market, both of which are expected to take effect by no later than 8:00 a.m. on 3 July 2026.

As a result of this announcement, Treatt is no longer in an "Offer Period" as defined in the Takeover Code and accordingly the dealing disclosure requirements previously notified to investors no longer apply.

Settlement of consideration

In accordance with the terms of the Scheme, a Scheme Shareholder on Treatt's register of members at the Scheme Record Time, being 6:00 p.m. on 1 July 2026, will be entitled to receive 305 pence in cash for each Scheme Share held.

Settlement of the cash consideration under the Acquisition to which Scheme Shareholders are entitled under the terms of the Scheme will be effected in the manner set out in the Scheme Document as soon as practicable and in any event, no later than 16 July 2026.

Board changes

As the Scheme has now become Effective, Treatt duly announces that, with effect from today's date, Sangita Shah, Christine Sisler, Shaun Smith and Helga Moelschl have stepped down as non-executive directors from the Company.
