Form 8.3 - Spirent Communications plc
Major Shareholding Notification Classification · 100% confidence The document is a 'Form 8.3' disclosure, which is a standard regulatory filing under the UK Takeover Code used to report positions and dealings in relevant securities by persons with interests of 1% or more. It is not a major shareholding notification (which typically triggers at 3% or higher thresholds) nor a director's dealing. Since it is a specific regulatory disclosure form required by the Takeover Panel, it falls under the 'Regulatory Filings' category.
2025-09-12 English
Rule 2.9 Announcement
Declaration of Voting Results & Voting Rights Announcements Classification · 100% confidence The document is a 'Rule 2.9 Announcement' issued by Spirent Communications plc. This is a standard regulatory disclosure required under the UK City Code on Takeovers and Mergers to confirm the total number of voting rights and issued share capital of a company during an offer period. While it relates to M&A activity, it is specifically a regulatory disclosure of share capital rather than a merger proposal or takeover bid document itself. Therefore, it falls under the 'RNS' (Regulatory Filings) category as a standard regulatory announcement.
