Filing Released Lang Actions
Form 8.3 - Spirent Communications plc
Major Shareholding Notification Classification · 98% confidence The document is explicitly titled 'FORM 8.3 - Spirent Communications plc' and references 'Rule 8.3 of the Takeover Code (the “Code”)'. This form is a mandatory disclosure required when a person holding interests of 1% or more in a company subject to a takeover bid makes a dealing or holds an opening position. This type of filing relates directly to insider/major shareholder activity during a takeover scenario. While it involves director/insider dealings (DIRS) and major shareholding notifications (MRQ), the specific context of 'Rule 8.3 of the Takeover Code' points most accurately to disclosures related to M&A activity, which is covered by the 'Takeover Activity Report' (TAR) definition, or more generally, insider dealing related to a takeover. Given the options, 'TAR' (M&A Activity) is the most specific category for disclosures mandated by the Takeover Code regarding an ongoing offer. If TAR were not available, DIRS or MRQ might be considered, but TAR captures the context of the 'Takeover Code' reference best.

Holding(s) in Company
Major Shareholding Notification Classification · 99% confidence The document is clearly identified by the header 'RNS Number : 2472J' 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. The content details the acquisition/disposal of voting rights by Morgan Stanley, crossing a threshold, and includes specific fields for share percentages and dates, confirming it is a regulatory filing related to share ownership changes. This fits the definition for Major Shareholding Notification (MRQ) better than the general Regulatory Filings (RNS), as MRQ is a specific category for this type of disclosure.

Form 8.3 - Spirent Communications plc
M&A Activity Classification · 98% confidence The document is explicitly titled 'FORM 8.3 - Spirent Communications plc' and references 'Rule 8.3 of the Takeover Code (the “Code”)'. This form is a Public Opening Position Disclosure/Dealing Disclosure made by a person holding 1% or more interest in relevant securities during a takeover situation. This type of disclosure relates directly to the ownership and trading of shares during a takeover or merger activity. Among the provided definitions, 'M&A Activity (Code: TAR)' is the most appropriate category as it covers 'Announcements and documents related to merger proposals or takeover bids.' While it is a specific regulatory filing, its content is entirely focused on the takeover process, making TAR a better fit than the general 'RNS' fallback.

This type of mandatory disclosure regarding significant changes in share ownership thresholds falls under the category of Major Shareholding Notification.
