Johnson Matthey Plc

Share buyback programme

Johnson Matthey Plc ("JM" or the "Company") announces that as outlined in its announcement on 20th March 2024, it will commence a share buyback programme to purchase ordinary shares of 110 49/53 pence each in the Company ("Ordinary Shares") for up to a maximum consideration of £250m. The first tranche of this share buyback programme of up to a maximum consideration of £125m (the "Programme") will commence immediately.

The Company has entered into an irrevocable, non-discretionary agreement with Citigroup Global Markets Limited ("Citi") to manage the Programme, pursuant to which Citi will purchase Johnson Matthey Ordinary Shares (acting as principal) for subsequent repurchase by the Company. Citi will make trading decisions under the Programme independently of JM. Purchases may continue during any closed period to which the Company is subject. The sole purpose of the share buyback programme is to reduce the share capital of the Company. All shares repurchased under the Programme will be cancelled.

The maximum number of shares that may be repurchased under the Programme is 18,345,341 shares, being the number of shares the Company is authorised to purchase pursuant to the authority granted by shareholders at the Company's 2023 Annual General Meeting (the "2023 AGM") and any subsequent authority.

Purchases of the Company's Ordinary Shares pursuant to the Programme will commence immediately and end no later than 4th November 2024.

Any purchase of Johnson Matthey ordinary shares in relation to this announcement will be effected within certain pre-set parameters and in accordance with Johnson Matthey's general authority to repurchase ordinary shares granted by its shareholders at the 2023 AGM, Chapter 12 of the Financial Conduct Authority's Listing Rules, the Market Abuse Regulation (EU) 596/2014 (as in force in the UK and as amended by the Market Abuse (Amendment) (EU Exit) Regulations 2019); and the Commission Delegated Regulation (EU) No 2016/1052 (as in force in the UK and as amended by the FCA's Technical Standards (Market Abuse Regulation) (EU Exit) Instrument 2019). No repurchases will be made in respect of the Company's American Depositary Receipts.
