Form 8.3 - Spirent Communications plc
Major Shareholding Notification Classification · 98% confidence The document is a 'Form 8.3' disclosure, which is a standard regulatory requirement under the UK Takeover Code for persons with interests in relevant securities representing 1% or more of an offeror or offeree company. It details positions and dealings in Spirent Communications plc. Since this is a specific regulatory disclosure form regarding shareholdings and dealings during a takeover period, it falls under the 'Regulatory Filings' category as it does not fit into the specific categories for director dealings or major shareholding notifications (which are typically distinct from the Takeover Code Form 8.3 disclosure process).

Total Voting Rights
Regulatory Filings Classification · 98% confidence The document is a standard regulatory announcement regarding 'Total Voting Rights and Capital' issued by Spirent Communications PLC. It provides the total number of voting rights and issued share capital to assist shareholders with transparency rule notifications. This type of disclosure is a routine regulatory requirement under the FCA's Disclosure Guidance and Transparency Rules and does not represent a change in capital (like a new share issue) or a transaction in own shares, but rather a periodic update of the denominator for transparency calculations. Therefore, it falls under the general regulatory filing category.
