First Equity Limited and Armstrong Investments Limited Increase XSG Stake to 4.02%

The TR-1 notification confirms that First Equity Limited, a London-registered firm, holds the stake in its capacity as investment manager for Armstrong Investments Limited, which is registered in Douglas, Isle of Man. The ultimate controlling entity behind this chain is identified as the Estate of William Black. All 34,650,000 voting rights are held directly through shares in Xeros Technology Group plc under ISIN GB00BMGYBJ57, with no financial instruments or indirect rights forming part of the position. The shares are held in the name of nominee vehicle Nortrust Nominees Limited, based in London.

Stake Rises from 3.09% to 4.02%, Triggering DTR5 Disclosure Obligation

Under UK Financial Conduct Authority Disclosure and Transparency Rules, shareholders must notify an issuer when their voting rights cross certain percentage thresholds. In this case, the position of the notifying parties rose from a previously notified level of 3.087322% to the current 4.020371%, crossing the 4% notification threshold on 30 October 2026. The issuer was notified on the same date, and the form was completed in London. No financial instruments or voting rights with similar economic effect are reported alongside the direct shareholding, meaning the entire position consists solely of ordinary shares.

Xeros Technology Group's Shareholder Register and Investor Considerations

Xeros Technology Group develops and licenses polymer bead technology, primarily targeting the textile and laundry sectors with water- and chemical-saving applications. The company operates as a UK issuer, with its shares admitted under ISIN GB00BMGYBJ57. Accumulation of a position above 4% by a single connected group of entities may prompt investors to monitor whether the stake continues to grow toward higher disclosure thresholds. The structured chain — from the Estate of William Black through Armstrong Investments Limited to First Equity Limited as manager — adds a layer of complexity to assessing beneficial ownership concentration within the XSG register.
