WPP shares surge after results, but Cindy Rose still has to solve the growth problem

WPP plc (LSE: WPP) has recovered dramatically from the market pessimism that surrounded the advertising group earlier in 2026 after its August 6 interim results showed that the decline in underlying revenue had slowed considerably during the second quarter. Revenue less pass-through costs fell 4.7% like-for-like to £4.75 billion in the first half, but the second-quarter decline narrowed to 2.8% from 6.7% in the first quarter, significantly better than investors had feared. Headline operating profit fell 3.4% to £398 million, while the headline operating margin edged 20 basis points higher to 8.4% as restructuring and lower staff costs began providing financial support. WPP shares jumped 28.6% on the results day and closed at 402 pence on August 11, leaving the stock close to its new 52-week high but also raising a more demanding question: has Cindy Rose merely stopped the deterioration, or has WPP created the foundations for sustainable revenue growth?

That distinction matters because the first-half numbers are still those of a contracting business. Reported revenue declined 4.4% to £6.37 billion and revenue less pass-through costs fell 5.6% on a reported basis, while headline earnings per share dropped 24.5% to 15.1 pence. The market nevertheless focused on the sequential improvement in the second quarter because WPP entered 2026 after several years of client losses, falling margins, management upheaval and investor concerns that artificial intelligence could weaken the economics of traditional advertising agencies. The August rally therefore looks less like investors pricing in a completed turnaround and more like the removal of a significant distress discount that had developed around the shares.

Why did WPP shares jump almost 29% when first-half revenue was still falling?

The magnitude of WPP’s share-price reaction initially looks disconnected from the financial statement because revenue did not return to growth and headline operating profit still declined. The explanation lies primarily in expectations: WPP’s second-quarter revenue less pass-through costs fell only 2.8% like-for-like, compared with a 6.7% decline in the first quarter and analyst expectations for a considerably steeper contraction. WPP Media improved from an 8.3% decline in the first quarter to 2.8% in the second, while WPP Creative improved from a 6.3% decline to 3.5%, giving investors evidence that the deterioration was no longer accelerating across the group’s two largest businesses.

The stock closed at £3.95 on August 6 after rising 28.62%, with approximately 20.7 million shares traded compared with a 50-day average near five million. It advanced again to £4.11 on August 7, briefly establishing a new 52-week high, before declining to £3.91 on August 10 and recovering to £4.02 on August 11. The fact that most of the results-day gain remained intact several sessions later indicates that the initial reaction was not immediately dismissed as a short-lived relief rally.

The valuation context also matters. Reuters Breakingviews estimated after the results that WPP traded at roughly six times the previous year’s earnings, compared with around 13 times for Publicis Groupe, highlighting how much pessimism had already been embedded in the British group’s shares. A low earnings multiple can produce an exceptionally large percentage rerating when investors conclude that the downside scenario has become less likely, even before the company demonstrates renewed growth.

Does the improvement from a 6.7% decline to 2.8% show that WPP has reached the bottom?

The sequential movement is encouraging, but it is too early to treat the second quarter as a definitive inflection point. Management itself continues to expect revenue less pass-through costs to decline by a low-to-mid-single-digit percentage during the second half, which means a return to positive organic growth is not embedded in the current 2026 outlook. The second quarter also benefited from easier comparisons, and WPP explicitly noted that some of the improvement reflected a smaller drag from legacy account losses rather than broad-based acceleration across every client category.

The customer data show why caution remains appropriate. Revenue less pass-through costs from WPP’s top 25 clients declined 6.3% during the first half, although the second-quarter decline improved to 3.2%. Consumer packaged goods, which represented 27% of the analysed client mix, fell 9.1% during the half, while Technology and Digital Services declined 9.2%, Telecom, Media and Entertainment fell 14.8% and Financial Services declined 13.4%. Healthcare and Pharma was one of the stronger areas with 2.9% growth, while Automotive returned to 3.6% growth during the second quarter.

Geographically, North America remained the largest concern with a 6% first-half decline and a 4.3% second-quarter contraction, while EMEA declined 4.3% for the half. APAC returned to marginal 0.3% growth in the second quarter and LATAM increased 0.9%, but China’s 15.6% second-quarter growth was partly affected by timing factors. WPP therefore has evidence that conditions are becoming less negative, but it does not yet have the broad regional and client-sector growth profile that would support describing the turnaround as complete.

Can Cindy Rose’s Elevate28 restructuring restore margins without cutting into future growth?

The first financial benefit from Elevate28 is already visible in WPP’s margin performance. Headline operating margin increased 20 basis points like-for-like to 8.4% despite the 4.7% decline in first-half revenue less pass-through costs, with lower severance, reduced staff costs and restructuring savings offsetting part of the revenue pressure. WPP expects approximately £100 million of in-year savings during 2026 and is targeting £500 million of gross annualised savings by 2028, creating potentially substantial operating leverage if revenue eventually stabilises and returns to growth.

The restructuring is much broader than traditional cost cutting because WPP is attempting to dismantle the old holding-company structure that allowed hundreds of agencies and brands to operate with overlapping management, technology and administrative functions. WPP Creative has been reorganised around four regional profit-and-loss structures, WPP Production has been consolidated and WPP Enterprise Solutions launched in July to target corporate demand for artificial-intelligence transformation. Management is also introducing common incentive structures intended to make teams collaborate across businesses rather than protect individual agency economics.

The financial risk is that reducing personnel and real estate can improve margins faster than it improves competitive positioning. Reuters Breakingviews noted that headcount and office reductions can stabilise profitability, but long-term recovery still depends on winning clients and generating revenue rather than indefinitely shrinking the cost base. That distinction should become increasingly visible during 2027 because WPP cannot reach its stated growth ambitions through savings alone once the largest restructuring benefits have been captured.

Are WPP’s new client wins enough to reverse the damage from earlier account losses?

There are signs that WPP’s commercial position is improving. First-half wins included consolidated mandates from The Estée Lauder Companies, Henkel and Wendy’s, while important accounts including Skechers, Tesco, Huawei, L’Oréal, Uber and Deutsche Bahn were retained across various markets. Reuters also reported that WPP had moved to the top of industry new-business rankings over the previous nine months, an important reversal after earlier losses damaged confidence in both WPP Media and the broader group.

Advertising revenue does not respond immediately to a contract win because onboarding, campaign planning and client spending schedules create a lag between securing an account and recognising significant income. This is one reason Cindy Rose has emphasised that organic growth remains the primary long-term objective while warning that improved commercial momentum will take time to flow fully through the reported numbers. The continued impact of historical account losses in the first half therefore does not necessarily contradict stronger recent new-business activity.

The real test will come when new wins become large enough to offset departing business and existing clients begin increasing spending. WPP Media still declined 5.4% during the first half and WPP Creative fell 4.9%, meaning both large operations need significantly better conversion from new business before the group can return to organic growth. A second-half decline that narrows toward the low end of management’s guidance would strengthen the argument that contract momentum is beginning to affect revenue, while another deterioration would challenge the narrative established by the August results.

Does artificial intelligence threaten WPP’s agency model or create its biggest new growth opportunity?

Artificial intelligence remains one of the most difficult variables in WPP’s valuation because the technology can simultaneously reduce the cost of producing advertising and create new services that clients are willing to buy. Generative AI can automate image creation, copy production, campaign adaptation, media optimisation and other activities that previously required significant human labour, potentially putting pressure on agency fees if clients expect the productivity benefits to be passed through. WPP is responding by attempting to make AI a central part of its own operating model rather than treating the technology as an external competitive threat.

WPP Open serves as the group’s primary technology platform, while Open Intelligence provides an AI-powered data layer intended to improve campaign planning and media outcomes. During the second quarter, WPP expanded relationships with Google, Meta and Amazon Web Services to integrate predictive and generative AI capabilities into the platform, including a cultural intelligence system developed with Google Cloud. Management says these tools are already being deployed with clients, making the commercial question less about whether WPP uses AI and more about whether its data and technology stack is differentiated enough to justify premium fees.

Publicis provides the most important competitive comparison because it has spent heavily acquiring proprietary data and technology assets and is currently valued materially more highly by the market. Reuters Breakingviews highlighted Publicis’ proposed LiveRamp acquisition as another step in strengthening the data available to AI systems, while also noting that Publicis is expected to have leverage of about 1.2 times EBITDA after the transaction compared with almost 2.2 times for WPP at the end of June. WPP therefore has to compete technologically while operating with less balance-sheet flexibility, making internal execution and asset recycling particularly important.

Why does WPP’s £2.9 billion adjusted net debt remain important after the share-price rebound?

Adjusted net debt stood at £2.94 billion at June 30, down from £3.26 billion a year earlier but significantly above the £2.17 billion recorded at the end of 2025. Average adjusted net debt was £3.30 billion, compared with £3.40 billion at the end of 2025, while changes to IFRS 9 reduced the reported June net-debt figure by £125 million. WPP therefore has evidence of gradual improvement in average debt but does not yet possess the financial flexibility enjoyed by some of its better-performing competitors.

Cash generation also remains under pressure during the restructuring. Adjusted operating cash flow before working capital declined 14.9% to £309 million in the first half, while WPP maintained full-year guidance of £800 million to £900 million. Net cash outflow from operating activities improved to £660 million from £1.04 billion a year earlier, but the seasonal first-half outflow means the second half remains critical for meeting the full-year cash target and improving financial leverage.

Asset disposals are intended to provide additional flexibility. WPP expects more than £200 million of proceeds from disposal-related activity during 2026 and has already completed a number of smaller transactions, while further portfolio decisions remain under consideration. Reducing debt through asset sales can strengthen the balance sheet, but the quality of the strategy depends on disposing of businesses that are genuinely non-core rather than sacrificing assets capable of producing attractive long-term cash flows simply to accelerate deleveraging.

Is WPP’s 12% to 13% full-year margin target realistic after only 8.4% in the first half?

The difference between the first-half margin and the full-year target initially looks large, but WPP’s earnings have historically been significantly weighted toward the second half. Management continues to expect a full-year headline operating margin of 12% to 13%, even while acknowledging that second-half margins could decline by as much as roughly 200 basis points year on year because spending on growth initiatives and employee incentives will increase. The key point is that WPP is deliberately reinvesting some cost savings rather than maximising near-term margin expansion.

This makes the margin target a useful measure of the quality of the turnaround. If WPP can maintain its 12% to 13% range while revenue remains under pressure and simultaneously invest in AI, data, client teams and incentives, it would demonstrate that the simplified operating model is generating structural savings. If the company has to cut investment more aggressively to defend margins, the near-term earnings outcome could improve at the expense of the longer-term growth strategy.

The comparison with 2025 provides important context. WPP’s full-year headline operating margin fell to 13% from 15% in 2024 as revenue declined and severance costs increased, while reported operating profit was also affected by significant impairment charges. The 2026 target therefore does not imply a rapid return to historical profitability; it represents an attempt to stabilise the economics of the business while rebuilding competitiveness.

What does WPP’s share price now imply after the post-results rerating?

WPP closed at 402 pence on August 11, up 2.94% for the session and only about 2.5% below the 413 pence 52-week high established on August 10. The shares had closed at 395 pence immediately after the interim results, meaning the dramatic 28.6% results-day gain has largely survived subsequent volatility. That resilience represents a significant change in sentiment compared with the months when investors were pricing WPP primarily around client losses, leverage and the threat of AI disruption.

The longer-term comparison remains less flattering. Reuters Breakingviews noted that WPP shares had lost around 60% over five years while Publicis had roughly doubled, reflecting a substantial divergence in growth, client momentum and investor confidence. The recent rally therefore recovers only part of the relative value destroyed during the previous strategy cycle.

This creates an unusual valuation setup. WPP remains inexpensive relative to Publicis on conventional earnings multiples, but part of that discount is justified by weaker revenue growth, higher leverage and a turnaround that remains unfinished. Further rerating will increasingly depend on measurable revenue improvement rather than another quarter in which the decline is merely less severe than expected.

Key takeaways from WPP’s 2026 interim results and Cindy Rose’s turnaround strategy

• WPP reported first-half revenue of £6.37 billion, down 4.4%, while revenue less pass-through costs fell 4.7% like-for-like to £4.75 billion.
• The second-quarter decline in revenue less pass-through costs narrowed to 2.8% from 6.7% in the first quarter, driving the sharp improvement in investor sentiment.
• WPP shares surged 28.6% on August 6 and closed at 402 pence on August 11, close to their new 52-week high.
• Headline operating profit fell 3.4% to £398 million, but the headline operating margin improved by 20 basis points to 8.4%.
• Elevate28 is expected to deliver £100 million of savings during 2026 and £500 million of gross annualised savings by 2028.
• WPP Media improved from an 8.3% first-quarter decline to 2.8% in the second quarter, while WPP Creative improved from a 6.3% decline to 3.5%.
• Adjusted net debt stood at £2.94 billion at June 30, while average adjusted net debt was £3.30 billion.
• WPP expects more than £200 million of disposal proceeds in 2026 as management simplifies the portfolio and creates additional financial flexibility.
• Management still expects second-half revenue less pass-through costs to decline by a low-to-mid-single-digit percentage and maintains a full-year headline operating margin target of 12% to 13%.
• The next major proof point is whether recent client wins and AI investment can move WPP from slowing decline to genuine organic growth during 2027.

Has WPP genuinely turned the corner, or has the market simply stopped pricing in the worst?

WPP’s August interim results have materially improved the investment narrative because the business no longer appears to be deteriorating at the rate investors feared earlier in the year. The sequential improvement from a 6.7% first-quarter decline to 2.8% in the second quarter, combined with new-business wins, better retention and early margin benefits from Elevate28, suggests Cindy Rose’s stabilisation programme is beginning to produce measurable effects. The share-price reaction reflects the importance of that change, but a 29% rally does not transform declining revenue into growth.

The strongest case for a sustained recovery is that WPP now has several mechanisms working simultaneously. Cost savings can provide funds for reinvestment, portfolio disposals can reduce financial pressure, WPP Open gives the company a common AI and data platform, and the simplified operating structure should make it easier to combine creative, media, production and enterprise technology capabilities for large clients. If recent account wins begin contributing materially to revenue while legacy losses fall out of the comparison, WPP could enter 2027 with a fundamentally healthier revenue trajectory.

The remaining risks are equally substantial. Publicis continues to grow from a stronger financial and data position, WPP’s largest client sectors remain under pressure and the group still carries almost £3 billion of adjusted net debt. Artificial intelligence could improve WPP’s productivity, but it can also reduce barriers to entry and place downward pressure on agency pricing unless the company proves that its proprietary data, strategy and global execution create value clients cannot reproduce internally.

The next stage of the WPP turnaround therefore has a much higher evidentiary standard than the first. Cindy Rose has shown that the decline can slow and that the organisation can be simplified, which was enough to remove a large amount of pessimism from the share price. To justify another major rerating, WPP must now demonstrate something the business has struggled to deliver for several years: sustainable organic revenue growth alongside improving cash generation and falling leverage.
