Corrected Filing Replaces 6 November 2026 Notification That Understated the Position

The disclosure carries a notable procedural element: the announcement explicitly states that this notification replaces one submitted on 6 November 2026, which understated the holding. The corrected TR-1, completed on 6 November 2026 and published via RNS on 9 November 2026, sets the definitive position at 6.28% with 50,778,700 voting rights as at the threshold-crossing date of 4 November 2026. Investors may be watching whether the original understatement was material and whether any further amendments to the register are required as a result of the error in the initial filing.

Regulatory Obligations Under DTR5 Triggered by Voting Rights Movement

The notification was triggered under the Financial Conduct Authority's Disclosure Guidance and Transparency Rules, specifically DTR5, which requires major shareholders to notify issuers when their voting rights cross prescribed thresholds. The movement from 10.00% to 6.28% crossed a reportable threshold, obligating Philip J Milton & Company to file the TR-1 form. The holding is classified entirely under section 8A of the notification as direct voting rights, with no positions reported under financial instruments categories 8B1 or 8B2. Built Cybernetics PLC has a UK issuer status, confirming the domestic regulatory framework applies.
