A London-based marketing consultancy which counts some of the biggest US tech names among its clients saw its shares halve following a profit warning.
Next 15 Group Plc, whose customers include Amazon.com., International Business Machines Corp., Salesforce Inc. and ByteDance Ltd.’s TikTok, plunged as much as 53% on Friday in its biggest one-day loss on record. The AIM-listed firm said that one of the biggest customers of its Mach49 business has not renewed a contract, which had been expected to add more than £80 million ($105 million) of sales in 2026.
