Form 8.3 - Spirent Communications plc
Major Shareholding Notification Classification · 100% confidence The document is a 'Form 8.3' disclosure, which is a mandatory regulatory filing under the UK Takeover Code. It details the interests and short positions of a person (Millennium International Management LP) in the relevant securities of an offeror/offeree (Spirent Communications plc). This type of disclosure is specifically required during M&A activity to ensure transparency regarding shareholdings and dealings. While it relates to M&A, it is a specific regulatory disclosure form rather than a general M&A announcement (TAR), and it does not fit into other categories like DIRS or MRQ as perfectly as it fits the 'Regulatory Filings' fallback category for specific regulatory forms.
