The slowdown is improving, even if the half-year still looks weak
The better read on WPPWPP-- is not just the H1 like-for-like net sales down 4.7%. It is that the decline is easing quickly, from Q1 revenue less pass-through costs down 6.7% LFL to a 2.8% LFL decline in Q2. That shift matters because investors are starting to ask less about how deep the damage was and more about whether the business is finding a floor.
Management has described this as the "Stabilise" phase on track, and it continues to expect an improving LFL trajectory in H2. If that holds, the next rerating path is straightforward: the market moves past one weak half-year and starts to price in a demand bottom.
The bullish case is credible. The quarter got less bad, and profitability held up better than sales, with headline operating profit margin (%) 8.4 versus 8.2% a year earlier. That suggests stabilization is possible without stripping out everything valuable.
Quick Backtesting Tool
The bearish case is also reasonable. WPP still faces a weak top-line backdrop, and the company has said the drag from client losses is expected to persist through 2026. This is stabilization, not a full growth recovery.
What investors need next is simple:
- Clear evidence that H2 demand improves as management expects
- Profitability that holds without another round of aggressive cuts
- Signs that new wins and renewals are translating into steadier revenue
New business and retention show demand is soft, but WPP is still competitive
The real ground-level test is whether clients are giving WPP more work. The answer is yes-but not enough yet to say the whole market has turned.
Wins are meaningful, even if the market is still soft
WPP finished H1 2026 ranking number one in JP Morgan's net new business rankings for H1 2026. In advertising, that matters. The wins were not marginal either: Estee Lauder, Jaguar Land Rover, and Airbnb suggest the pitch engine is still working at a high level.
That does not prove a broad upcycle. It does show WPP still has credibility with major brands even in a weak spending environment.
Retention matters as much as new business
New-business wins get the headlines, but retention keeps the business stable. WPP said client retention rates improved in H1 2026, with key renewals including Huawei, Tesco, and L'Oreal. That is a useful signal that the company is not relying only on fresh pitches to offset churn.
The key distinction is between better business development and a wider recovery in ad spending. WPP can still win and keep accounts while the macro tape remains cautious.
What would confirm the improvement
The remaining weakness shows up mostly in category demand, not in WPP's ability to compete. Even with stronger pitching and retention, the company is still operating in a market where some key sectors remain soft.
The next proof points investors need are:
- More renewals, not just more pitches won
- Retention that stays firm quarter after quarter
- Evidence that new wins are building through into sustained revenue
- Signs that the improvement in Q2 is repeating in H2
If those signals continue, the market is more likely to treat new-business momentum as durable. If they fade, the story remains a good operating performance in a weak market.
Profit held up, but cash flow and debt still have to improve
The next question is not whether WPP has cut costs. It is whether the company is getting better at turning work into cash and profit, or simply becoming cheaper to run.
Lower EPS and weaker cash flow are still red flags
The bear case starts with the basics: headline diluted EPS fell to 15.1p from 20.0p, adjusted operating cash flow pre WC 309 fell from £363m, and adjusted net debt 2,935 remains significant. If the only thing improving is the cost base, investors are underwriting a smaller WPP, not a better one.
That is a real warning, not a minor one. Even so, the company is not leaning only on belt-tightening. Management still expects headline operating profit margin to be 12% to 13%, which means the plan has to be about better execution and a softer demand backdrop, not just paying fewer bills.
What would show real operational improvement
A service business can look cheaper quickly by cutting costs, delaying investment, or managing timing. A healthier business keeps client work flowing, converts that work into cash, and still preserves room to invest.
WPP has shown one side of that with ranking number one in JP Morgan's net new business rankings for H1 2026 and improved client retention. The harder test now is whether those wins are strong enough to offset weaker cash generation and still support the margin target over the rest of the year.
What to watch over the next few quarters
For investors, the next few quarters should answer one question: are operations improving on their own, or is shrinkage doing most of the work?
Watch for:
- Cash flow recovery that tracks with the sales improvement
- Stable or better retention as the year progresses
- Margin progress that comes from mix and execution, not only cost control
- A clear H2 improvement in LFL revenue, as management expects
That keeps the positioning intact: it is still too early to call a clean turnaround. If cash flow and retention improve alongside demand, the stock can shift from "cost cutter" to "recovery." If not, the upside case stays unfinished.
