Source: Companies House, priced allotments filed on form SH01; Tero analysis, 12 October 2026. Step-up is the latest priced round divided by the first substantive priced round; option-scheme and nominal issues are excluded. Bar lengths are drawn on a square-root scale so the largest values do not flatten the rest; the printed number is the figure. Implied valuation is price per share times shares in issue after the latest priced allotment. Information, not investment advice.
