Shares in GlobalData plunged on Monday after the data and analytics group warned that full-year profits would fall short of market expectations as weaker-than-expected revenue growth and increased investment pressured margins.
The shares were down 24.7% at 53.9p by 0947 BST, having touched a fresh 52-week low of 52.61p earlier in the session.
GlobalData said underlying revenue growth had been "more muted than expected" in the first half, and now expects full-year revenues to come in towards the lower end of the current analyst consensus range of £325.3m to £335.7m.
Meanwhile, targeted investment in AI-native workflows, proprietary data and human expertise means full-year margins are now expected to be broadly in line with the first-half adjusted EBITDA margin of 34%, leaving adjusted EBITDA below market expectations. Consensus currently stands at £121.0m to £126.7m.
The warning represents a deterioration from July, when GlobalData had expected full-year adjusted EBITDA merely to be at the low end of consensus.
For the six months to 30 June, revenue rose 4% to £162.9m, although underlying growth was just 1%. Adjusted EBITDA increased 5% to £54.8m, while reported pre-tax profit fell 6% to £23.2m because of higher finance charges.
Free cash flow dropped 27% to £31.3m and operating cash flow fell 23% to £50.8m. Net bank debt stood at £133.0m, compared with £16.8m a year earlier.
Chief executive Mike Danson said: "Revenue and growth remained below our ambitions and the benefits of the transformation have not yet been reflected in our financial performance."
Stocks with AI links tumbled in Asia after the chief executives of Anthropic and OpenAI called over the weekend for the pace of development of AI models to slow down for safety reasons. Raspberry PI fell sharply on the news whereas related stocks that would benefit from a slower AI development such as WPP, Playtech and Trainline made gains.
