Director/PDMR Shareholding
Director's Dealing Classification · 100% confidence The document is titled 'DIRECTOR / PDMR SHAREHOLDING' and details a transaction involving a Director/PDMR (Paula Bell, CFO) purchasing ordinary shares under an employee share purchase plan. This directly corresponds to the definition of Director's Dealing (insider trades by executives). The RNS Number format and the closing statement referencing RNS, the London Stock Exchange, and the FCA confirm it is a regulatory disclosure. The specific category for director share transactions is 'DIRS'.

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 used for 'PUBLIC OPENING POSITION DISCLOSURE/DEALING DISCLOSURE BY A PERSON WITH INTERESTS IN RELEVANT SECURITIES REPRESENTING 1% OR MORE' in the context of a takeover offer. This type of filing relates directly to insider/significant shareholder activity during a takeover scenario. Among the provided categories, 'Director's Dealing (DIRS)' covers personal share transactions by executives, and while this is a dealing disclosure by a significant shareholder (Millennium International Management LP) related to a potential takeover, the specific context of takeover code disclosures often falls under regulatory filings or insider trading reports. Since the document details specific dealings and positions related to a takeover offer, it is most closely aligned with reporting insider/significant shareholder transactions. 'DIRS' (Director's Dealing) is the closest fit for reporting share transactions by interested parties, even if the filer is an investment manager rather than a director, as it captures significant ownership changes/dealings relevant to corporate control events like takeovers. However, given the explicit reference to the Takeover Code (Rule 8.3), which is a specific regulatory requirement during M&A, it is a specialized disclosure. If 'TAR' (M&A Activity) is reserved for the proposal/bid itself, then this specific disclosure about interests during the bid is best categorized as a specialized regulatory filing concerning ownership changes during M&A. Since 'DIRS' covers insider trades, and this is a mandatory disclosure of a significant position/dealing during a takeover, it fits the spirit of insider transaction reporting. Given the options, 'DIRS' is the most appropriate fit for reporting significant shareholder dealings related to a corporate action, although 'RNS' (Regulatory Filings) is a strong secondary candidate if 'DIRS' is strictly limited to directors. Given the nature of the disclosure (dealing/position disclosure by a major holder), DIRS is selected as the best fit for insider/significant holder transaction reporting.

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 contains detailed tables regarding the acquisition or disposal of voting rights by a shareholder (Barclays PLC) in the issuer (Spirent Communications PLC). This structure and content are characteristic of regulatory filings related to changes in significant share ownership thresholds. The presence of 'RNS Number' and the closing statement referencing RNS, the news service of the London Stock Exchange, confirms it is a regulatory announcement. The specific filing type for notification of changes in significant share ownership is 'Major Shareholding Notification' (MRQ).

Holding(s) in Company
Major Shareholding Notification Classification · 99% confidence The document is explicitly labeled with 'RNS Number : 0710K' and contains the standard header 'This information is provided by RNS, the news service of the London Stock Exchange.' The content details a 'TR-1: Standard form for notification of major holdings' concerning HSBC Holdings plc crossing a threshold of voting rights in Spirent Communications PLC. This type of mandatory disclosure regarding significant changes in share ownership falls directly under the definition of Major Shareholding Notification (MRQ). Although it is distributed via RNS, the specific content dictates the MRQ classification over the general RNS fallback.

Form 8.3 - Spirent Communications plc
Major Shareholding Notification Classification · 99% 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 filing relates directly to corporate control, mergers, and acquisitions activity, specifically concerning takeover bids. Among the provided definitions, 'M&A Activity (Code: TAR)' is the most appropriate category as it covers merger proposals or takeover bids, and Form 8.3 is a mandatory disclosure during such events.

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 or Dealing Disclosure made by a person holding 1% or more interest in relevant securities during a takeover situation. This type of filing relates to insider/significant shareholder activity during a takeover bid, which falls under the scope of M&A activity or specific regulatory disclosures related to takeovers. Since there is a specific category for M&A Activity (TAR), and this document is directly related to a takeover situation involving Spirent Communications plc, TAR is the most appropriate classification. It is not a general Director's Dealing (DIRS) as it is specifically tied to the Takeover Code rules (Rule 8.3) concerning an offer.
