Next Gen Mobility Limited's Stake in IES Drops Below the 10% Disclosure Threshold

The TR-1 form filed on 12 November 2026 confirms that Next Gen Mobility Limited, registered in St Peter Port, Guernsey, now holds 7.83% of voting rights in Invinity Energy Systems, down from a previously notified position of 11.27%. The total number of voting rights held — 64,102,564 — remains unchanged from the prior notification, indicating that the percentage decline reflects a change in the total voting rights pool of Invinity Energy Systems rather than a sale of shares by Next Gen Mobility Limited. This distinction is material for investors assessing the nature of the shareholding shift.

Voting Rights Structure Confirms Direct Holding With No Financial Instruments Attached

According to the notification, all 64,102,564 voting rights are held directly by Next Gen Mobility Limited under DTR5.1, with no indirect holdings and no financial instruments such as options, warrants, or contracts for difference declared in sections B1 or B2 of the TR-1 form. The company further states it is not controlled by any natural person or legal entity and does not control any other undertaking holding an interest in Invinity Energy Systems. This straightforward direct-holding structure provides clarity on the nature of the position.
