Result of Secondary Share Sale

Further to the announcement made on 11 June 2025, Louis Hall (the "Selling Shareholder") announces the sale of 3,043,295 ordinary shares ("Placing Shares") in the share capital of Cerillion at a price of 1500 pence per Placing Share, which represents approximately 10.3% of Cerillion's issued share capital (excluding ordinary shares held in treasury) (the "Placing").

The Placing was underpinned by very strong support from existing shareholders, and certain non-holders, including from the USA, UK and Europe, have joined the share register. The Placing remained significantly over-subscribed at the increased transaction size.

This is CEO Louis Hall's first sale of shares since 2017. The sale diversifies his asset base, broadens the shareholder base and significantly increases liquidity, supporting the Company's future growth prospects. Following completion of the Placing, Louis Hall remains the Company's largest shareholder with a resultant holding of 5,944,414 ordinary shares, representing 20.1% of Cerillion's issued share capital (excluding ordinary shares held in treasury).

The Placing, conducted through an accelerated bookbuild, raised aggregate gross proceeds of £45.6 million. Panmure Liberum Limited ("Panmure Liberum") acted as sole bookrunner for the Selling Shareholder in connection with the Placing.

The Selling Shareholder has undertaken not to dispose of any further Ordinary Shares in Cerillion for a period of 365 days following completion of the Placing, subject to certain exceptions and waiver by Panmure Liberum ("Lock-in period"). In addition, the Seller has undertaken to adhere to an orderly market provision for a further 180 days on conclusion of the Lock-in period.

The trade date for the Placing will be 12 June 2025 and settlement is expected to occur on 16 June 2025.

Cerillion will not receive any proceeds from the Placing.
