Filing Released Lang Actions
Price Monitoring Extension
Regulatory Filings Classification · 99% confidence The document is very short (1929 characters) and contains the header 'RNS Number : 3772K'. It announces a 'Price Monitoring Extension' related to trading procedures on the London Stock Exchange. The text explicitly states, 'This information is provided by RNS, the news service of the London Stock Exchange.' This strongly indicates a general regulatory announcement that does not fit into the specific categories like 10-K, ER, or DIV. According to Rule 2, since it is a brief announcement of a procedural event rather than a comprehensive report, and it is clearly sourced from the RNS system, the most appropriate classification is Regulatory Filings (RNS).

Second Price Monitoring Extn
Regulatory Filings Classification · 98% confidence The document is very short (1946 characters) and announces a 'Second Price Monitoring Extension' related to trading activity on the London Stock Exchange, identified by the 'RNS Number : 3642K'. It explicitly states that the information is provided by RNS, the news service of the London Stock Exchange, which is approved by the Financial Conduct Authority (FCA) to act as a Primary Information Provider. This type of immediate, short-form regulatory update that doesn't fit into specific financial reporting categories (like 10-K, ER, or IR) is best classified as a general Regulatory Filing, which corresponds to the RNS code.

Price Monitoring Extension
Regulatory Filings Classification · 98% confidence The document is very short (1929 characters) and contains the header 'RNS Number : 3625K'. It announces a 'Price Monitoring Extension' related to trading procedures on the London Stock Exchange and explicitly states that the information is provided by RNS, the news service of the London Stock Exchange, which is approved as a Primary Information Provider. This structure—a brief announcement about a market event or procedural update distributed via the RNS system—fits the definition of a general regulatory announcement that doesn't fit a specific financial report category. Therefore, the most appropriate classification is Regulatory Filings (RNS).
2022-12-20 English
Pyebridge SPA Deferred Consideration Settlement
Regulatory Filings Classification · 98% confidence The document begins with 'RNS Number : 9152J' and is dated '16 December 2022'. It details a specific corporate action: the settlement of deferred consideration related to an asset acquisition (Pyebridge SPA Deferred Consideration Settlement). This type of announcement, which conveys material, non-public information to the market via the Regulatory News Service (RNS) system, fits the definition of a general regulatory announcement. Since it is not a full financial report (10-K, IR), a specific management change (MANG), or a dividend notice (DIV), the most appropriate general category for a standard regulatory news service release is RNS.
2022-12-16 English
TR-1: Notification of major holdings
Major Shareholding Notification Classification · 99% confidence The document is identified by the header 'RNS Number : 8807J' and contains the standard formatting for a regulatory news service announcement from the London Stock Exchange. The content is explicitly titled 'TR-1: Standard form for notification of major holdings' and details changes in voting rights percentages (e.g., from 61.27% to 57.86%) held by a shareholder ('Kibo Mining (Cyprus) Limited'). This type of filing, which reports changes in significant share ownership thresholds, directly corresponds to the definition of Major Shareholding Notification (MRQ). Although it is distributed via RNS, the specific content dictates the MRQ classification over the general RNS fallback.
2022-12-15 English
Second Price Monitoring Extn
Regulatory Filings Classification · 98% confidence The document is very short (1946 characters) and contains the header 'RNS Number : 7485J'. It announces a 'Second Price Monitoring Extension' related to trading activity on the London Stock Exchange. It explicitly states, 'This information is provided by RNS, the news service of the London Stock Exchange.' This indicates it is a general regulatory announcement disseminated via the RNS system, rather than a specific financial report (like 10-K, IR, or ER). Since it is a general regulatory announcement that doesn't fit the other specific categories (like DIRS, DIV, or DLST), the most appropriate classification is the general Regulatory Filings fallback category.
