Filing Released Lang Actions
Half-year Report
Interim / Quarterly Report Classification · 100% confidence The document is titled 'Unaudited interim results for the six-month period ended 30 June 2024' and contains detailed financial statements, including a statement of comprehensive income, revenue analysis, and management commentary on performance. It is a comprehensive financial report for a period shorter than a full fiscal year, fitting the definition of an Interim/Quarterly Report (IR). H1 2024
2024-08-30 English
Business Update
Capital/Financing Update Classification · 99% confidence The document begins with 'RNS Number : 9790A' and is dated '20 August 2024'. It contains standard regulatory boilerplate language at the end, mentioning 'RNS, the news service of the London Stock Exchange' and 'Market Abuse Regulation (EU No. 596/2014)'. The content announces operational updates (genset overhaul commencement, application for increased contract) rather than being a full financial report (like 10-K or IR) or a proxy statement. Since it is a formal announcement distributed via the RNS system that doesn't fit a more specific category like DIV, ER, or CAP, it falls best under the general Regulatory Filings category, which serves as the fallback for miscellaneous regulatory announcements distributed through official channels.
2024-08-20 English
TR-1 Notification
Major Shareholding Notification Classification · 99% confidence The document is identified by the 'RNS Number' header and contains a 'TR-1: Standard form for notification of major holdings'. This form details changes in voting rights and financial instruments held by a shareholder (Spreadex LTD), specifically noting the date the threshold was crossed (12-Aug-2024) and the date of notification (13-Aug-2024). This type of filing, which reports changes in significant share ownership, directly corresponds to the Major Shareholding Notification category (MRQ). Although it is distributed via RNS, the specific content dictates the MRQ classification over the general RNS fallback.

TR-1 Notification
Major Shareholding Notification Classification · 99% confidence The document is titled 'TR-1: Standard form for notification of major holdings' and details changes in voting rights due to an acquisition or disposal of financial instruments by a shareholder (Spreadex LTD). This type of filing specifically reports changes in significant share ownership thresholds. This 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.

Pyebridge Revenue Update re Refurbished Genset
Earnings Release Classification · 99% confidence The document begins with an 'RNS Number' and is dated '07 August 2024'. It contains an announcement from 'Mast Energy Developments PLC' detailing operational and revenue updates for one of its assets (Pyebridge), including key financial highlights (revenue, margin, output) for July 2024. The text explicitly states, 'Mast Energy Developments PLC... is pleased to announce an update regarding its Pyebridge flexible power generation asset'. This structure—a brief announcement of operational or financial progress, often referencing a specific regulatory service like RNS—is characteristic of an Earnings Release (ER) or a general Regulatory Filing (RNS). Since it provides specific, recent performance data (July revenue/output) but is not a comprehensive quarterly report (IR) or the full annual report (10-K), it fits best as an Earnings Release (ER) which covers period-specific results highlights. It is not a mere announcement of a report's publication (RPA) because it contains the substantive data itself. Q3 2024
2024-08-07 English
TR-1 Notification
Regulatory Filings Classification · 98% confidence The document is a formal notification filed under the RNS (Regulatory News Service) system, indicated by the 'RNS Number' and the concluding boilerplate text referencing RNS and the London Stock Exchange. The content is specifically a 'TR-1: Standard form for notification of major holdings' concerning an acquisition or disposal of financial instruments by Spreadex LTD, resulting in a change in their voting rights percentage (crossing below the 10% threshold, now at 9.186400%). This type of filing reports personal share transactions by significant shareholders or executives (insider trades/major holdings changes). This aligns directly with the definition for Director's Dealing (DIRS), which covers personal share transactions by directors and executives, and by extension, major shareholders reporting changes in holdings. Since the core content is a major holding notification (TR-1), the most appropriate code is DIRS, as it captures significant insider/major shareholder activity, which is closely related to director dealings in terms of regulatory focus on ownership changes.
