Form 8.3 - Spirent Communications plc
M&A Activity Classification · 98% confidence The document is explicitly titled "FORM 8.3 - PUBLIC OPENING POSITION DISCLOSURE/DEALING DISCLOSURE BY A PERSON WITH INTERESTS IN RELEVANT SECURITIES REPRESENTING 1% OR MORE" and references "Rule 8.3 of the Takeover Code (the “Code”)". This form is used in the context of a takeover or merger activity to disclose significant shareholdings or dealings by parties involved. Among the provided codes, the closest fit for documents related to takeover bids or merger proposals is 'TAR' (M&A Activity). Although this is a specific disclosure form (Form 8.3), its purpose is directly tied to the M&A process governed by the Takeover Code.

Form 8.3 - Spirent Communications plc
Major Shareholding Notification Classification · 99% confidence The document is explicitly titled "FORM 8.3 - PUBLIC OPENING POSITION DISCLOSURE/DEALING DISCLOSURE BY A PERSON WITH INTERESTS IN RELEVANT SECURITIES REPRESENTING 1% OR MORE" and references "Rule 8.3 of the Takeover Code (the “Code”)". This form is used in the context of a takeover or merger activity to disclose significant holdings or transactions by parties involved. This directly aligns with the definition of M&A Activity (TAR), which covers merger proposals or takeover bids, as this disclosure is a mandatory filing during such an event. It is not a general Director's Dealing (DIRS) as it relates to a specific takeover context and is filed by an investment manager (Millennium International Management LP) regarding an offeree (Spirent Communications plc).

Form 8.3 - Spirent Communications plc
Major Shareholding Notification Classification · 97% confidence The document is explicitly titled "FORM 8.3 - PUBLIC OPENING POSITION DISCLOSURE/DEALING DISCLOSURE BY A PERSON WITH INTERESTS IN RELEVANT SECURITIES REPRESENTING 1% OR MORE" and references "Rule 8.3 of the Takeover Code (the “Code”)". This form is used in the context of a takeover bid (indicated by the reference to 'offeror/offeree' and 'Takeover Code') to disclose significant holdings or transactions by parties involved. This type of disclosure, related to insider/major shareholder activity during a takeover scenario, is most closely aligned with Director's Dealing (DIRS) or Major Shareholding Notification (MRQ). However, since it is a specific regulatory disclosure related to insider/major shareholder activity (Millennium International Management LP disclosing a position in Spirent Communications plc during a potential offer), and given the options, it represents a specific type of insider/major shareholder transaction reporting. While DIRS usually refers to director trades, this is a major shareholder disclosure under takeover rules. Given the options, it is a specific regulatory filing concerning share ownership/dealing during a corporate action. Since it details dealings and positions of a major shareholder/stakeholder during a takeover, it falls under the scope of insider/major shareholder reporting. If a more specific 'Takeover Disclosure' existed, that would be ideal. Comparing the available codes, 'DIRS' (Director's Dealing) is the closest fit for personal/insider transaction reporting, although this is a fund manager. 'MRQ' (Major Shareholding Notification) is also relevant as it discloses a position crossing a threshold. Given the context of the Takeover Code, which mandates these disclosures, and the nature of reporting significant interests/dealings, it is a specialized regulatory filing. Since it is a mandatory disclosure under the Takeover Code regarding interests/dealings, and not a general dividend, capital, or standard earnings report, it fits best as a specialized regulatory filing. In the absence of a specific 'Takeover Disclosure' code, and noting that it details dealings/positions of a significant party, it is best classified as a specialized regulatory filing that reports on share ownership changes/interests, which aligns closely with the intent of DIRS or MRQ. Given the explicit reference to 'Dealing Disclosure' and 'Interests', and the fact that it is a mandatory disclosure under the Takeover Code, it is a specific regulatory filing. I will classify it as DIRS as it reports on significant dealings/positions by an interested party, which is the closest analogue for insider/major stakeholder reporting among the choices, or RNS as a general regulatory filing. Since it is a highly specific regulatory form (Form 8.3), RNS (Regulatory Filings) is the safest fallback, but DIRS captures the essence of reporting on insider/major stakeholder transactions. I will lean towards DIRS as it concerns the dealing/position of a major stakeholder, which is a form of insider reporting, even if the party isn't strictly a director.

Holding(s) in Company
Major Shareholding Notification Classification · 99% confidence The document is explicitly titled 'TR-1: Standard form for notification of major holdings' and is filed via 'RNS Number : 8013S'. It details changes in voting rights and financial instruments held by a shareholder (Qube Research & Technologies Limited), crossing a notification threshold. This type of filing, reporting changes in significant share ownership, directly corresponds to the Major Shareholding Notification category. Although it is an RNS filing, the specific nature of the content (major holding notification) makes 'MRQ' (Major Shareholding Notification) a more precise classification than the general 'RNS' fallback.

Form 8.3 - Spirent Communications plc
Major Shareholding Notification Classification · 99% confidence The document is explicitly titled 'FORM 8.3 - PUBLIC OPENING POSITION DISCLOSURE/DEALING DISCLOSURE BY A PERSON WITH INTERESTS IN RELEVANT SECURITIES REPRESENTING 1% OR MORE' and references 'Rule 8.3 of the Takeover Code (the “Code”)'. This form is used in the context of a takeover or merger activity to disclose significant holdings and dealings by parties involved. This directly aligns with the definition of M&A Activity (TAR), which covers merger proposals or takeover bids, as this disclosure is a mandatory part of the M&A regulatory framework in the UK (Takeover Code). It is not a general Director's Dealing (DIRS) as it relates specifically to a takeover context and is a mandatory disclosure for a 1%+ holder, not just a director's personal trade.

Holding(s) in Company
Major Shareholding Notification Classification · 98% confidence The document is clearly identified by the header 'RNS Number : 4594S' 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 (insider/major shareholder transactions). This specific filing reports that Morgan Stanley's holding crossed a threshold, resulting in a new total voting rights percentage of 6.670233%. This type of filing, reporting director/insider transactions or major shareholder changes, maps directly to the 'Director's Dealing' category (DIRS) or, more broadly, a regulatory notification. Since 'Director's Dealing' (DIRS) specifically covers personal share transactions by directors and executives, and this is a major shareholder notification (which often falls under similar disclosure rules), I must check the provided definitions. The definition for DIRS is 'Report of personal share transactions by company directors and executives (insider trades)'. While this is a major shareholder (Morgan Stanley), the closest specific category for ownership changes by significant parties is DIRS, or the general regulatory filing category RNS. However, the TR-1 form is a specific regulatory disclosure regarding ownership changes, which is often grouped with insider dealings or major shareholding notifications. Given the options, 'Major Shareholding Notification' (MRQ) is defined as 'Notification of changes in significant share ownership levels (crossing thresholds)'. This is the most precise fit for a TR-1 filing reporting a change in holding that crosses a threshold, even if the holder is an institution rather than an executive.
