Transaction in Own Shares
Transaction in Own Shares Classification · 100% confidence The document is an official announcement released via RNS (RNS Number: 4443Q) on July 10, 2025. The title explicitly states 'Transaction in own shares'. The content details the purchase of 37,568 ordinary shares by Costain Group PLC as part of its share buyback programme, including aggregate and individual trade details. This directly corresponds to the definition of 'Transaction in Own Shares' (Code: POS). Although it is an RNS filing, the specific nature of the transaction (share repurchase) makes POS the most accurate classification over the general RNS fallback.

Major Shareholding Notification Classification · 99% confidence The document is explicitly identified by the header 'RNS Number : 2328Q' and contains the standard disclaimer regarding RNS being the news service of the London Stock Exchange, approved by the FCA. The content itself is a 'TR-1: Standard form for notification of major holdings' concerning UBS Group AG's change in shareholding in Costain Group PLC, crossing below the 5% threshold. This type of mandatory disclosure regarding changes in significant share ownership is classified as a Major Shareholding Notification (MRQ). Although it is distributed via RNS, the specific content dictates the MRQ classification over the general RNS fallback.
