WPP · WPP PLC

The thesis

WPP's shares have pulled back about 5% from their 52-week high into the 29 October 2026 third-quarter trading update, and the update settles the case. It needs to show a like-for-like decline in revenue less pass-through costs narrower than the second quarter's 2.8%, with the 12–13% full-year headline operating margin guidance intact. This note was written before the release figures were available, so the result is not reflected here.

The New York line closed at $25.80 on 28 October 2026, 5.4% below its 52-week high of $27.28 on the adjusted daily series. The shares are up 30.1% over three months, and the 14-day relative strength index (RSI) reads 56.6. WPP has published no results since the 6 August 2026 interims, and on 23 September 2026 it said 2026 guidance was unchanged.

The narrative is maturing: the stabilisation story is well known, and the shares have drifted lower since the 15 October 2026 high of $27.16 reported in the previous note. The only fresh account news is the 22 October 2026 Coca-Cola decision, which went broadly as the September reports signalled. The rating stays at coverage level because the main test arrives today and the prior-year comparison is easy, which the market already knows.

Bullish and bearish views on WPP PLC

The bull case on WPP PLC (WPP), in brief: Guidance reaffirmed after the quarter ended. The bear case: Comparisons are easy.

Bull case

• Guidance reaffirmed after the quarter ended. WPP's 23 September 2026 announcement said 2026 guidance is unchanged from the interims. That guidance is a 12–13% headline operating margin, £800–900m of adjusted operating cash flow before working capital, and a low-to-mid single-digit like-for-like decline in second-half revenue less pass-through costs. WPP
• Second-quarter decline narrowed. The 6 August 2026 interim results showed revenue less pass-through costs down 2.8% like-for-like in the second quarter, against 4.7% for the first half. Like-for-like strips out currency moves and acquisitions or disposals. For the 25 largest clients the decline narrowed to 3.2% in the second quarter from 6.3% for the half. WPP interim results
• Coca-Cola's global media business kept. On 22 October 2026 Coca-Cola said WPP's Open X will remain its media partner globally, except North America, Japan and South Korea. Adweek and The Drum describe the retained work as a major win, and The Drum values the global media business at about $2bn. Adweek
• A sell-side target went up. Berenberg raised its London target to GBX 470 from GBX 405 in mid-September and repeated Buy on 29 September 2026. Daily Political

Bear case

• Comparisons are easy. WPP's 6 August 2026 statement credited easier comparisons with part of the second-quarter improvement. Yahoo Finance reported that third-quarter 2025 revenue less pass-through costs fell 5.9% like-for-like, so a smaller decline this year partly reflects a weak base.
• Coca-Cola North America went to Omnicom. The 22 October 2026 decision gave Omnicom the North America media account, which Digiday estimates at $700–800m. The roll-out starts in phases on 1 December 2026, so the loss weighs on 2027 revenue rather than the quarter reported today.
• CFO departure during the restructuring. On 23 September 2026 WPP announced that CFO Joanne Wilson will leave to become CFO of Diageo, serving a 12-month notice period while the board searches for a successor. The Elevate28 restructuring targets £500m of annual savings by 2028.
• Not every analyst is positive. Sharecast reported Goldman Sachs starting coverage of WPP at sell with a 240p target, in an item dated 11 August 2026, while rating Publicis and Omnicom buy.

Price setup

The last adjusted close was $25.80 on 28 October 2026. The 52-week high is $27.28, and the 1 October 2026 close of $25.22 marked the low of the recent consolidation. The shares sit 2.3% above that level, so a weak update could break it in one session.

The 14-day RSI of 56.6 is down from 61.6 on 15 October 2026. Three-month gains of 30.1% leave the shares well above where they traded in July, so the report is being judged against a higher price than the interims were.

Crowding evidence is limited to what is observable: the report is due today, and the three-month gain is large. Company filings and news show no share issuance, and no insider transactions are in recent filings.

Catalysts, next 30 days

• 1 December 2026: Coca-Cola North America transition to Omnicom begins, per Mediaweek and B&T. This falls after the 30-day window but fixes the timing of the lost revenue.
• ~2 December 2026, est.: FTSE UK Index Series December quarterly review. WPP has been outside the FTSE 100 since December 2025, and changes would take effect around 18 December 2026.

Elapsed catalysts

• 29 October 2026: Q3 2026 trading update, covering the three and nine months to 30 September 2026, with a 9:00 BST analyst call. It shows whether the second-quarter 2.8% decline was a turning point and whether the margin and cash-flow guidance hold. (passed 8d ago)

What would change the view

The case breaks if the third-quarter like-for-like decline in revenue less pass-through costs is worse than the second quarter's 2.8%, or if WPP cuts the 12–13% headline operating margin guidance or the £800–900m cash-flow guidance. Either would show the second-quarter improvement came from easy comparisons.

On price, a weekly close below $25.22, the 1 October 2026 close, would end the consolidation. A third-quarter decline narrower than 2.8% with guidance unchanged would strengthen the case, but the shares have already priced much of that. Further top-25 client losses, or no CFO successor well into the notice period, would also weaken it.

What it trades with

WPP trades with other advertising holding companies such as Omnicom and Publicis, which gain or lose on the same client reviews. The New York line is a depositary receipt over London-listed ordinary shares, so its returns include the pound-dollar exchange rate. Its moves also follow US consumer-goods advertising budgets and artificial-intelligence disruption fears across the sector.
