Net revenue for the first half of 2025 was GBP 328.2 million, down 10% like-for-like and 12.7% reported. Reported revenue was GBP 360.4 million, down 11.9% like-for-like and 14.7% reported. Operational EBITDA was GBP 20.8 million, a 6.3% margin, down 190 basis points like-for-like and 170 basis points reported; adjusted operating profit was GBP 16.4 million and adjusted EPS was 0.2p versus 1.2p a year earlier. Free cash flow was GBP 16 million, net debt was GBP 145.9 million, and leverage was 2x pro forma 12-month operational EBITDA. For 2025, management expects like-for-like net revenue down by mid-single digits, operational EBITDA broadly similar to 2024, net finance cash charge of around GBP 29 million, effective tax rate of 30% to 32%, and year-end net debt of GBP 100 million to GBP 140 million.

Martin Sorrell said the first half was in line with expectations, but the company is still being hit by macro uncertainty, tariff concerns, and client caution. He emphasized that wins such as General Motors, Amazon, T-Mobile, PIF and a soon-to-be-announced U.S. FMCG client should ramp in H2, creating a stronger second-half weighting than usual. His tone was cautiously confident, with repeated emphasis on the AI opportunity, cost discipline, and longer-term growth potential.

Radhika Radhakrishnan focused on the financial squeeze and the cash response. She cited GBP 20.8 million of operational EBITDA, a 6.3% margin, GBP 16 million of free cash flow, and net debt of GBP 145.9 million, improved by GBP 37 million year over year; month-end average net debt improved by GBP 52 million. She also said personnel and operating expenses were reduced by 11.2%, headcount ended around 6,900, and a cost reduction plan is being rolled out in H2 to move staff costs from 76% toward industry averages of 65%. She noted the EUR 375 million term loan matures in August 2028, the GBP 100 million RCF remains undrawn, and capital allocation will return cash via dividends and buybacks once net debt falls below GBP 100 million.

There was no analyst Q&A, so the main back-and-forth came from management’s prepared remarks. The most notable concerns raised were client spend pressure in technology, longer sales cycles in Technology Services, and the impact of macro and tariff uncertainty on new business timing. Management answered by saying tech spending cuts have stabilized, key client losses are mostly out of the comp, AI-related demand is creating new pipeline, and second-half performance should improve.
