Filing Released Lang Actions
Scrip Dividend Reference Price
Notice of Dividend Amount Classification · 95% confidence The document is an RNS release announcing the Scrip Dividend Reference Price, the dividend payment date, record date, and instructions for shareholders to elect the scrip dividend alternative. This fits squarely within dividend announcements, specifically under Notice of Dividend Amount (DIV). It is not a full report, earnings release, or regulatory filing; it is a dividend notice.

Director/PDMR Shareholding
Director's Dealing Classification · 94% confidence The document is a regulatory announcement under the UK Market Abuse Regulation detailing the exercise of share awards by PDMRs (the CEO and CFO) and subsequent transactions including sales and transfers. It enumerates beneficial holdings, transaction details (exercise of LTIP and SDP options, sale for tax/NIC, transfers to spouse), dates, volumes, prices, and provides the required Notification of Dealing Forms. This fits precisely the definition of Director's Dealing (insider transactions by company directors).

Transaction in Own Shares
Transaction in Own Shares Classification · 98% confidence The document is an RNS announcement titled “Transaction in own shares” detailing the company’s purchases of its ordinary shares under its buyback programme and giving aggregate and daily purchase data.

2026-04-22 English
Holding(s) in Company
Major Shareholding Notification Classification · 92% confidence The document is an RNS “TR-1: Standard form for notification of major holdings” used to report UBS trading book holdings in Costain Group PLC falling below 5%, thus notifying a change in significant share ownership threshold.
