("JSG", the "Company" or the "Group")

Commencement of Share Buyback Programme

On 7 May 2026, in its AGM Statement (the "AGM Statement"), the Company announced that, in addition to the £90.3 million returned to Shareholders through share buybacks since 2022, it intends to launch a further £55.0 million share buyback programme (the "Buyback Programme").

Pursuant to the Buyback Programme, the Company has today entered into a non-discretionary instruction with Investec Bank plc to purchase up to £55.0 million (excluding expenses) of the Company's Ordinary Shares of 10 pence each (the "Shares") and to make trading decisions under the Buyback Programme independently of the Company in accordance with certain pre-set parameters. The Buyback Programme will commence today and end no later than 1 March 2027.

As set out in the AGM Statement, the Company employs a disciplined approach to investment, returns and capital efficiency to deliver sustainable compounding growth whilst maintaining a strong balance sheet. Having taken into consideration recent investments, acquisitions, share buybacks and the payment of a final dividend for the financial year ended 31 December 2025, the Group has significant headroom under its recently refinanced and increased £175.0 million committed revolving credit facility (with a further £50.0 million accordion option, subject to lender consent). Accordingly, the Board considers the Buyback Programme to be prudent, reflecting the Group's cash generative ability and consistent with its capital allocation policy, and will continue to actively review its options on capital allocation, evaluating the balance between investment in our acquisition strategy, organic growth ambitions and returns to Shareholders.

The purpose of the Buyback Programme is to reduce the share capital of the Company. As such, the Company will cancel any Shares purchased.

Any purchase of Shares under the Buyback Programme will take place in open market transactions and may be made from time to time depending on market conditions, share price and trading volumes. The Buyback Programme will be effected under the general authority to repurchase Ordinary Shares granted by the Company's Shareholders at the Company's 2025 annual general meeting (and subject to renewed authority at the Company's 2026 annual general meeting) and in accordance with Chapter 9 of the UK Financial Conduct Authority's Listing Rules, and Regulation (EU) No 596/2014 and Commission Delegated Regulation (EU) No 2016/1052 (both as they form part of UK domestic law by virtue of the European Union (Withdrawal) Act 2018), including where relevant pursuant to the UK Market Abuse Regulation.

Any purchase of Shares pursuant to the Buyback Programme will be announced by no later than the end of the 7th daily market session following the calendar day on which such transaction occurred.
