Filing Released Lang Actions
Director/PDMR Shareholding
Director's Dealing Classification · 1% confidence The document is identified by the 'RNS Number' header and contains a notification dated 08 November 2017 regarding a 'Director/PDMR Shareholding'. Specifically, it details the purchase of shares by an entity closely associated with a Director (Martin Diggle) and reports the resulting change in ownership percentage. This type of filing, reporting personal share transactions by company directors and executives (insider trades), directly matches the definition for Director's Dealing (DIRS). Although it uses the RNS system, DIRS is a more specific classification than the general RNS fallback.

Holding(s) in Company
Major Shareholding Notification Classification · 1% confidence The document is clearly identified by the header 'RNS Number : 8458U' and contains the standard structure for a 'TR-1: Standard form for notification of major holdings'. This form is used to report changes in significant share ownership thresholds, which falls under regulatory disclosure requirements concerning major shareholdings. The specific category for notification of changes in significant share ownership levels (crossing thresholds) is 'Major Shareholding Notification' (MRQ). Although it is distributed via RNS, the content is highly specific to major holdings disclosure, making MRQ the most precise classification over the general RNS fallback.

Director/PDMR Shareholding
Director's Dealing Classification · 1% confidence The document is explicitly marked with an 'RNS Number' and contains the header 'RNS Number : 8464U'. The content details a 'Director/PDMR Shareholding' notification, specifically reporting the purchase of shares by an entity closely associated with a Director (Vulpes Life Sciences Fund purchasing shares, linked to Martin Diggle). This type of insider transaction disclosure is a standard regulatory filing. While it relates to director dealings (DIRS), the format and source (RNS) strongly suggest it is being disseminated via the Regulatory News Service. Since the primary function is a regulatory disclosure of insider trading, 'DIRS' (Director's Dealing) is the most specific fit among the options that cover transaction reporting by insiders. However, given the explicit RNS header and the nature of the announcement being a mandatory disclosure, 'RNS' (Regulatory Filings) is also a strong candidate if DIRS is considered too narrow. Reviewing the definitions, DIRS is for 'Report of personal share transactions by company directors and executives (insider trades)'. This document perfectly matches that description. Therefore, DIRS is the most accurate classification.

Holding(s) in Company
Major Shareholding Notification Classification · 1% confidence The document is explicitly labeled with "RNS Number : 3432U" and contains the standard format for a "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 (MRQ). Although it is distributed via RNS, the specific content dictates the classification as MRQ, as MRQ is a more specific category than the general RNS fallback.

Director/PDMR Shareholding
Major Shareholding Notification Classification · 1% confidence The document begins with an 'RNS Number' and is dated October 23, 2017. The content explicitly details share purchases by an entity (Vulpes Life Sciences Fund) that is closely associated with a Director (Martin Diggle) of the issuer (Proteome Sciences plc). This structure, focusing on transactions by PDMRs (Persons Discharging Managerial Responsibilities) or closely associated persons, is characteristic of insider trading disclosures required by regulatory bodies, often disseminated via RNS. Specifically, it reports on Director/PDMR Shareholding. While it is disseminated via RNS, the core subject matter is the transaction by a director/insider, which maps directly to the 'Director's Dealing' category (DIRS). It is not a general regulatory filing (RNS) or a major shareholding notification (MRQ), as it focuses on an insider's transaction, not just crossing a major threshold by a passive investor.
