WPP (LSE:WPP) Stock Could Be 22% Overvalued On 2026 Outlook Reaffirmation

WPP has enjoyed a sharp share price recovery over the past year, and that rebound puts a spotlight on a simple question for anyone looking at the stock today. Are investors now paying a price that the group's underlying cash flows can realistically support, given how the business is evolving?

• WPP shares are up 54.9% over the past year, which puts a lot more weight on whether the current valuation lines up with what its cash flows can deliver.
• Recent updates around media growth, creative pressures and the Elevate28 cost and efficiency plan may influence future margins and the timing of cash generation for the group.

The issue now is whether the cash flows implied by WPP's current share price look well supported by the business it has today and the plans already on the table.

Is WPP Getting Expensive on Cash Flow?

The Discounted Cash Flow (DCF) model here hinges on what WPP can turn its current operations into over the next decade. Latest twelve month free cash flow sits at about £905.6 million, so the starting point is sizeable, but the projections then assume free cash flow steps down before settling into a more modest long run profile rather than climbing aggressively.

On that setup, the DCF output suggests an intrinsic value that is meaningfully below the current £4.06 share price. This implies the market is paying up for improvements that are not fully embedded in these cash flow estimates. The recent share rise after WPP reaffirmed its 2026 margin ambition and pointed to media stabilisation partly explains why the traded price runs ahead of what this particular model supports right now.
