Johnson Matthey Plc

Johnson Matthey Plc ("JM") is pleased to announce that, following completion of the sale of its Catalyst Technologies business to Honeywell Technologies on 17 July 2026, a circular setting out full details of the proposed special dividend and associated share consolidation (the "Circular") has been published today.

The Circular confirms that JM intends to return approximately £1 billion of net sale proceeds to JM shareholders, comprising approximately £800 million through a special dividend of 476.5 pence per existing ordinary share in the capital of JM (the "Special Dividend") and approximately £200 million through an on-market share buyback programme.

The Circular sets out full details of the proposed Special Dividend and associated 3 for 4 share consolidation (the "Share Consolidation") and also contains a notice convening a general meeting of JM to be held at Herbert Smith Freehills Kramer, Exchange House, Primrose Street, London EC2A 2EG at 9.00 a.m. on Tuesday 11 August 2026 (the "General Meeting").

Special Dividend

JM confirms that it intends to return approximately £800 million to shareholders by way of a proposed Special Dividend of 476.5 pence per existing ordinary share. The Board is proposing to pay the Special Dividend to shareholders on the register as at 6.00 p.m. on Friday 14 August 2026 in pounds sterling. An equivalent amount in US dollars is proposed to be paid to those American Depositary Receipt (ADR) holders that are on the ADR register as at 5.00 p.m. (New York time) on Friday 14 August 2026 (being the close of business on the record date for the Special Dividend for the American Depositary Shares (ADSs)).

Subject to (i) shareholder approval of the Special Dividend and the Share Consolidation; and (ii) admission in respect of the new ordinary shares, the Special Dividend is expected to be paid to shareholders on Friday 28 August 2026 and to ADR holders commencing Tuesday 8 September 2026.

The proposed Special Dividend is in addition to JM's ongoing shareholder returns policy¹.

Share Consolidation

It is proposed that, subject to (i) shareholder approval of the Special Dividend and the Share Consolidation; and (ii) admission in respect of the new ordinary shares, the payment of the Special Dividend be accompanied by a consolidation of JM's ordinary share capital on the basis of 3 new ordinary shares with nominal value of 147  pence for every 4 existing ordinary shares.

The effect of the Share Consolidation will be to reduce the number of existing ordinary shares in issue by approximately the same proportion of market capitalisation returned via the Special Dividend (the market capitalisation for which will be as of market close on Wednesday 22 July 2026). It is anticipated, therefore, that the market price of each ordinary share in JM should remain at a broadly similar level following the Special Dividend and the Share Consolidation.

As all ordinary shareholdings in JM will be consolidated, the number of ordinary shares held by each shareholder will reduce, but the proportion of the total issued ordinary share capital of JM held by each shareholder immediately before and following the Share Consolidation will remain unchanged, save for fractional entitlements and any subsequent participation in the Dividend Reinvestment Plan. Apart from having a different nominal value, each new ordinary share will carry the same rights as set out in JM's articles of association which currently attach to the existing ordinary shares.

As further explained in the Circular, fractional entitlements arising from the Share Consolidation will be aggregated and sold in the market. The proceeds of such sale of fractional entitlements of £5.00 or less will be retained for the benefit of JM. The value of any one shareholder's fractional entitlement will not exceed the value of one new ordinary share.

Additional resolutions

Given the change in the share capital of JM, shareholder approval will also be sought to renew the annual authorities to enable JM to allot new ordinary shares, disapply pre-emption rights and buy back its own shares to cover the period between the date of the General Meeting and JM's 2027 Annual General Meeting. Further details of these additional resolutions are set out in the Circular.

Expected timetable

As set out in the Circular, the expected timetable for the General Meeting, the Special Dividend and the Share Consolidation is as follows (unless otherwise stated, references to time are to London time):

Availability of the Circular

A copy of the Circular will be posted to shareholders shortly. A copy of the Circular has been submitted to the National Storage Mechanism and will shortly be available for inspection at https://data.fca.org.uk/#/nsm/nationalstoragemechanism.

In addition, a copy of the Circular will be available for inspection on JM's website at https://matthey.com/general-meeting-2026.

Capitalised terms used but not otherwise defined in this announcement have the same meaning given to them in the Circular.
