IMI Cancels 269,000 Shares Purchased via Deutsche Numis Across Four Venues

The announcement states that Deutsche Numis executed the 30 October 2026 purchases across four trading venues: the London Stock Exchange (125,000 shares at a weighted average of 2,895.5687p), Turquoise (9,000 shares at 2,888.2462p), Chi-X (31,000 shares at 2,887.4765p), and BATS (104,000 shares at 2,883.8505p). The spread of execution across multiple venues is consistent with standard market practice for programmes operating under Article 5(1)(b) of the Market Abuse Regulation as incorporated into UK law, ensuring best execution and regulatory transparency throughout the trading day.

IMI's Total Voting Rights Fall to 235,771,674 Following Settlement and Cancellation

Following settlement and cancellation of the 269,000 purchased shares, IMI's total ordinary shares in issue will stand at 247,420,510. The company holds 11,648,836 ordinary shares in treasury, which do not carry voting rights, reducing the total number of voting rights to 235,771,674. This figure is significant for shareholders and institutional investors because it serves as the denominator for calculating percentage shareholdings and notification thresholds under the UK's Disclosure Guidance and Transparency Rules. Each successive cancellation tranche modestly reduces the absolute voting rights base.

Trades Executed Between 08:11 and 15:35 UK Time Reflect Active Intraday Participation

The full trade-by-trade breakdown published in the announcement shows that Deutsche Numis executed transactions continuously from 08:11 UK time through to approximately 15:35, spanning the full London trading session. Individual trade sizes ranged from single-share lots to blocks of 25,000 shares, with two notable block transactions of 25,000 shares each executed at 2,912.00p and 2,900.00p respectively. The majority of trades were conducted on BATS and the London Stock Exchange, with supplementary volume placed on Chi-X and Turquoise, reflecting a broad multi-venue strategy throughout the session.

Buyback Programme Structured Under UK Market Abuse Regulation Safe Harbour Provisions

The disclosure confirms the programme operates under Article 5(1)(b) of the Market Abuse Regulation as it forms part of UK law, providing a regulatory safe harbour for companies repurchasing their own shares subject to defined conditions on price, volume, and reporting. IMI's LEI is recorded as 2138002W9Q21PF751R30. A key risk specific to IMI's buyback activity is that sustained repurchases at elevated price levels may be dilutive to value if the programme continues during periods of price weakness, though the precise total size or remaining authorisation of the current programme was not disclosed in this announcement.
