Holding(s) in Company
Major Shareholding Notification Classification · 99% confidence The document is explicitly titled 'TR-1: Standard form for notification of major holdings' and contains an 'RNS Number'. This format is characteristic of regulatory notifications concerning changes in significant share ownership, specifically reporting transactions by insiders or major shareholders crossing notification thresholds. The content details the shareholder (UBS Group AG), the date the threshold was crossed, and the resulting total voting rights, which aligns perfectly with the definition of Major Shareholding Notification. The code for this is MRQ.

It includes detailed tables of individual transactions, aggregate volume, and price data, which is characteristic of a 'Transaction in Own Shares' filing.

Transaction in Own Shares
Transaction in Own Shares Classification · 100% confidence The document is an RNS (Regulatory News Service) announcement from Costain Group PLC, dated June 30, 2025. The title explicitly states 'Transaction in own shares'. The content details the purchase of 282,996 Ordinary Shares on June 27, 2025, as part of a 'share buyback programme', and provides aggregate and individual trade details. This directly corresponds to the definition of 'Transaction in Own Shares' (Code: POS). Although it is distributed via RNS, the specific content is about share repurchase, making POS the most accurate classification.

Holding(s) in Company
Major Shareholding Notification Classification · 99% confidence The document is clearly identified by the header 'RNS Number : 8155O' and contains the standard disclosure format 'TR-1: Standard form for notification of major holdings'. This form is used to report changes in significant share ownership, which directly corresponds to the definition of Major Shareholding Notification. The content details the acquisition of voting rights by UBS Group AG, crossing a threshold on 25-Jun-2025. This aligns perfectly with the 'Major Shareholding Notification' category (MRQ). Although it is distributed via RNS, the specific content dictates the classification over the general RNS fallback.

Transaction in Own Shares
Transaction in Own Shares Classification · 100% confidence The document is an RNS announcement from Costain Group PLC dated June 27, 2025. The title explicitly states 'Transaction in own shares' and details the purchase of Ordinary Shares under a 'share buyback programme'. This directly corresponds to the definition of a Transaction in Own Shares (share repurchase/issuance). Code mapping check: - 'Transaction in own shares' maps directly to 'Transaction in Own Shares (Code: POS)'. - It is not a general Earnings Release (ER), Annual Report (10-K), or Director's Dealing (DIRS), although it involves insider activity related to share structure, the specific action is the repurchase of shares by the company itself.
