The UK's Top Growth Companies (October 2026)
UK growth companies ranked.
Eighteen names made our list of the UK's top growth companies, and the top reads like two different economies. Rolls-Royce leads at an MGI of 66, growing revenue 13% a year with improving operating leverage, while Arm, the $161B chip designer, sits second at 62. Further down, Immunocore compounds revenue 62% a year, the fastest grower in this top ten.
A median MGI of 51.5 signals a shorter bench than the continental lists, so read this one name by name. Dilution discipline varies widely: BAE Systems grows revenue per share faster than its headline rate, while Rolls-Royce keeps only 6% of its 13% top line on a per-share basis. Each company opens to a full citation-backed analysis.
