The advertising industry has long operated on a principle that might be called "learned helplessness" when it comes to account losses: they happen, they hurt, and then everyone moves on to the next pitch. WPP, it seems, would like to try something different.

Cindy Rose, the chief executive who took over the world's largest advertising company nearly a year ago, said WPP was developing what she called a "client success program" — a formal system designed to identify accounts at risk of departure before the review notice arrives. The initiative, Ms. Rose said on a call with reporters following the company's interim results, would standardize how WPP's agencies manage retention and bring "more operational discipline" to client relationships across the organization.

"It will help us identify retention risks early," Ms. Rose said, "and be much more operationally disciplined and bring more excellence to our service delivery model."

The program arrives at a moment when WPP could use some early warnings. Revenue less pass-through costs fell 4.7 percent on a like-for-like basis during the first half of 2026, a decline the company attributed in part to major account losses from the previous year. Revenue from WPP's 25 largest clients — the relationships that tend to define whether a holding company is thriving or merely surviving — dropped 6.3 percent over the same period.

Yet investors, who have grown accustomed to parsing advertising holding company results for signs of directional improvement rather than outright health, responded favorably. The rate of decline eased in the second quarter, and WPP's shares rose sharply in early trading.

Ms. Rose pointed to retention wins including Huawei in China, Tesco in the United Kingdom and L'Oréal in Australia and New Zealand. She also struck a note of realism that executives at holding companies do not always permit themselves.

"Defensive pitches are a feature of this industry and we're not going to win them all," she said. "And frankly, we don't need to win them all."

(One imagines the early-warning system will be calibrated accordingly.)
