Filing Released Lang Actions
Heathrow Site Visit
Regulatory Filings Classification · 98% confidence The document is a short announcement (under 5,000 characters) issued via RNS (Regulatory News Service) regarding a site visit for analysts and investors. It explicitly states that 'No new material information or guidance will be disclosed' and provides a date for a future financial report. Since it is a regulatory announcement that does not contain the actual financial report or a substantive presentation, it falls under the RNS category as a general regulatory filing.

Costain awarded Anglian Water contract extension
Environmental & Social Information Classification · 99% confidence The document is identified by the header 'RNS Number : 4348L' and concludes with distribution information from 'Reach, the non-regulatory press release distribution service of RNS, part of the London Stock Exchange.' This strongly indicates a general regulatory announcement or press release distributed via the RNS system. The content details a contract extension secured by Costain Group PLC with Anglian Water for pipeline work. This type of operational/contract news, when distributed via RNS and not fitting into specific financial reporting categories (like 10-K, ER, or DIV), defaults to the general regulatory announcement category. Given the structure (RNS Number, date, announcement of contract win, contact details, and RNS footer), the most appropriate classification is Regulatory Filings (RNS). It is not a specific financial report, management change, or dividend notice.

Holding(s) in Company
Major Shareholding Notification Classification · 100% confidence The document is a 'TR-1: Standard form for notification of major holdings' filed by Costain Group PLC. It details an acquisition of voting rights by UBS Group AG, crossing a specific threshold. This type of regulatory disclosure regarding significant share ownership changes is classified as a Major Shareholding Notification (MRQ).

Total Voting Rights
Declaration of Voting Results & Voting Rights Announcements Classification · 100% confidence The document is a notification filed via RNS (RNS Number: 0877L) on June 2, 2025. It explicitly states the 'Total Voting Rights and Capital' as of May 31, 2025, detailing the total number of issued ordinary shares (272,998,475) and noting that this figure is the denominator for shareholder disclosure calculations under FCA rules. This content directly relates to the company's capital structure and share count, which is a specific type of regulatory disclosure. While it involves capital, it is not a financing announcement (CAP) or a share issue/repurchase (SHA/POS), but rather a mandatory periodic notification of the total share count. Since it is a formal regulatory announcement distributed via RNS, and it doesn't fit perfectly into the other specific categories like DIV, DVA, or SHA, it falls under the general regulatory announcement category, RNS, which serves as a fallback for mandatory disclosures not covered elsewhere. However, given the specific nature of reporting total voting rights, it is closely related to capital structure updates. Reviewing the definitions, it is a mandatory disclosure about the total number of shares, which is a fundamental aspect of capital structure reporting. Since it is a standard, periodic regulatory update distributed through the RNS system, RNS is the most appropriate general classification if a more specific one isn't available. The document is short and is an announcement of a regulatory status update, not the full report itself.

Holding(s) in Company
Major Shareholding Notification Classification · 99% confidence The document is explicitly labeled as 'TR-1: Standard form for notification of major holdings' and originates from 'RNS Number : 0819L' and is provided by 'RNS, the news service of the London Stock Exchange.' This form details an acquisition or disposal of voting rights by a major shareholder (UBS Group AG), crossing a notification threshold. This type of filing, which reports changes in significant share ownership, directly corresponds to the Major Shareholding Notification category (MRQ). Although it is a regulatory filing, MRQ is more specific than the general RNS fallback.

Holding(s) in Company
Major Shareholding Notification Classification · 99% confidence The document is clearly identified by the header 'RNS Number : 6362K' and the concluding statement: 'This information is provided by RNS, the news service of the London Stock Exchange.' The content itself is a 'TR-1: Standard form for notification of major holdings,' detailing an acquisition of voting rights by UBS Group AG, crossing a threshold. This type of mandatory disclosure regarding changes in significant share ownership is best classified under Major Shareholding Notification (MRQ). Although it is an RNS filing, MRQ is the more specific category for this content type.
