Mark Read, Chief Executive Officer of WPP, said:

"In a world being rapidly reshaped, we need to continue to evolve our offer to clients and simplify our business. I am excited by the creation of the world's largest creative agency, VML, and the continued evolution of GroupM. Both these developments will strengthen our offer to clients, simplify the integration of our services and maximise the returns on our ongoing investments in AI and technology.

"Our top-line performance in Q3 was below our expectations and continued to be impacted by the cautious spending trends we saw in Q2, particularly across technology clients with more impact from this felt in GroupM over the summer than the first half.

"We continue to win both creative and media assignments from leading global companies including significant wins in the third quarter with Estée Lauder (media), Hyatt (creative), Lenovo (creative), Nestlé (media) and Verizon (creative). Our net new business performance of $1.4bn in the quarter showed sequential improvement after a tougher first half.

"We will provide more detail on today's announcements, our strategic roadmap and actions to drive growth, further efficiencies and margin expansion at our Capital Markets Day in January."

Looking ahead

We have made great progress over the last five years, investing in creativity and technology and behind fewer, stronger agency brands strengthening our offer to clients. We have attracted new talent, particularly in the United States, and invested in data and technology capabilities with a common approach that supports collaboration and delivers results to clients. Our early investments in AI can be seen in the many examples of work that we are doing for clients. We also moved quickly, through the sale of Kantar, to address our leverage and ensure our balance sheet is in a much stronger position, while returning surplus capital to shareholders and paying a long-term sustainable dividend.

Much has been achieved, but the world is changing fast, and there is now more to do, particularly as we look out at the environment over the next five years, to ensure that WPP remains relevant and competitive to major global and local clients.

Today we have outlined two strategic initiatives that will strengthen our client proposition, further simplify WPP and better equip us to navigate a future more shaped by technology.

1. VML: Creation of the world's largest integrated creative agency.

VML will bring together the people, creativity, commerce, data and technology offering of two of our most successful agencies: VMLY&R and Wunderman Thompson. The combined agency will benefit from the complementary nature of their geographic strengths as well as bringing world-class capabilities in CRM, data, experience design, influencer marketing, marketing technology and ecommerce to the clients of both agencies.

VML will be operational on 1 January 2024 with more than 30,000 people and will provide clients with the highest level of creativity, commerce, data and technology expertise in 64 markets globally. It will be led by Jon Cook as CEO, who has successfully led VMLY&R and, prior to that, VML since 2011, and Mel Edwards as Global President who previously led Wunderman Thompson for five years.

2. Simplification of GroupM's operating model.

GroupM embarked on a simplification plan in 2020 under new leadership which will now accelerate and move to a second phase. The new structure will retain its strong agency brands, EssenceMediacom, Mindshare, Wavemaker and mSix&Partners, but support them with common media products and a single technology platform, with shared services in finance, IT and HR.

One element of this is GroupM Nexus, GroupM's performance media organisation, which provides the agencies with a unified digital media offering and in the third quarter retired certain individual brands including Xaxis, Finecast and Sightline.

The creation of VML and the simplification of GroupM will strengthen these companies' competitive positions, allow further investment in client-facing expertise and help them to accelerate their growth. In addition, the reduction in operational complexity and duplication that accompanies these changes is expected to result in net annualised cost savings of at least £100m in FY25, with a part-year benefit in FY24. Associated expected restructuring costs are anticipated to be predominantly in FY24. The carrying value of brands impacted or retired by these actions will be assessed as part of our regular impairment review process and this may result in additional non-cash charges in the fourth quarter.

These net savings are in addition to the expected benefit from the transformation plan which we set out in December 2020, designed to achieve £600m in gross annual cost efficiencies by 2025 (with £200m net savings). We are on target to achieve an annual run-rate of £450m in efficiencies this year, against a 2019 baseline.

We will provide more details on these actions and our strategic roadmap to drive growth and margin expansion over the next five years at a Capital Markets Day in January.

Q3 overview

Revenue in the third quarter was £3.5bn, down 1.8% from £3.6bn in Q3 2022, and up 2.3% like-for-like. Revenue less pass-through costs was £2.8bn, down 5.0% from £3.0bn in Q3 2022, and down 0.6% like-for-like.

Business segment review

Revenue less pass-through costs

Global Integrated Agencies: GroupM, our media planning and buying business, saw LFL growth in revenue less pass-through costs of +1.6% in Q3 (YTD +4.6%), on lower spend from technology clients and the impact of client losses in the United States resulting in low-single-digit growth in the US and UK and a slight decline in Germany. This offset good growth in APAC markets.

Our digital billings mix within GroupM increased to 51%, compared to 48% in FY 2022.

In our integrated creative agencies, a LFL decline of 1.1% in Q3 (YTD -0.9%) represented an improvement on Q2's LFL of -2.3%.

Ogilvy grew well, supported by recent new business wins including SC Johnson and Verizon B2B.

Other integrated creative agencies, Wunderman Thompson, VMLY&R, AKQA Group and Hogarth all felt a continued impact from reduced spend across the technology sector and delays in technology-related projects.

Public Relations: FGS Global continued to grow well in Q3 while H+K and BCW both saw LFL declines, with all three agencies impacted by client caution in the face of macroeconomic uncertainty, primarily in the USA.

Specialist Agencies: continued strong growth in our specialist healthcare media planning and buying agency, CMI Media Group, was offset by reduced client spending in a number of our smaller stand-alone specialist agencies.

Regional review

Revenue less pass-through costs

North America declined by 4.1% in the third quarter, primarily reflecting lower year-on-year revenues from technology clients and the expected impact of 2022 client losses in the retail sector. This was partially offset by growth across CPG, healthcare and financial services clients, with GroupM and Ogilvy both growing in the quarter.

The United Kingdom grew with CPG and healthcare continuing to grow, but at a slower rate than in H1, offset by declines in technology client spend. Western Continental Europe saw declines in Germany on lower spend by automotive, technology and government clients and in France due to client losses; offset by growth in Spain and other markets.

The Rest of World saw continued growth in the quarter but was held back by China where a slower than expected macro recovery impacted our integrated creative agencies. India LFL growth accelerated to 7.3% in the quarter with a strong performance in media driven by new business wins.

Strategic progress

There have never been more opportunities for advertisers to reach consumers, reflected in the plethora of marketing channels available. Our clients continue to invest in their brands and seek our support as they navigate this complexity. In this increasingly complex world, WPP continues to invest in our offer to make it more relevant than ever.

In our creative production activities, we are moving to leverage scale and our investments in AI and production technology. We are concentrating our investments here in Hogarth which will take on all creative production activity not already aligned there and expand its operations into all our key markets. This will provide clients with a single world-class production operation with high standards of craft backed by the latest technology.

We believe that AI will be fundamental to WPP's business and are excited by its transformational potential and will cover the opportunity for WPP in more detail at our Capital Markets Day. Our expertise in the application of AI to marketing is based on investments that we have been making over many years, including the appointment of a Head of Creative AI in 2019 and the acquisition of Satalia in 2021.

AI is used extensively across our business today, particularly in GroupM and in Hogarth. Our application of AI includes automation of workflows, speeding up the process of ideation and concepting, and producing innovative creative work for clients.

Clients: We have won $3.4bn of net new business billings in the first nine months of 2023 (YTD 2022: $5.1bn) including the potential loss of certain Pfizer assignments currently held by WPP integrated creative agencies. Key assignment wins in Q3 included Estée Lauder, Hyatt, Lenovo, Nestlé, Unilever and Verizon B2C. Our performance in the third quarter picked up after a somewhat disappointing first half.

Creativity and awards: Creativity is at the heart of our offer, and we continue to be recognised for our creative excellence. WPP was named holding company of the year and VMLY&R network of the year at the New York Festivals Advertising Awards. Ogilvy was the most awarded agency at the Global Influencer Marketing Awards for the fifth year running and was recently named AdWeek's 2023 Global Agency of the Year. WPP global marketing effectiveness consultancy Gain Theory was recognised by Forrester as a Wave Leader in marketing measurement and optimisation.

Purpose and ESG

WPP's purpose is to use the power of creativity to build better futures for our people, planet, clients and communities. Read more on the ways WPP is working to realise a more sustainable, equitable future in our 2022 Sustainability Report.

Average adjusted net debt for the twelve months to 30 September 2023 was £3.5bn, compared to £2.5bn for the twelve months to 30 September 2022, an increase of £1.0bn. The increase was primarily due to the 2022 share buyback programme.

As such, all forward-looking statements involve risk and uncertainty because they relate to future events and circumstances that are beyond the control of the Company. Actual results or outcomes may differ materially from those discussed or implied in the forward-looking statements. Therefore, you should not rely on such forward-looking statements, which speak only as of the date they are made, as a prediction of actual results or otherwise. Important factors which may cause actual results to differ include but are not limited to: the impact of, epidemics or pandemics including restrictions on businesses, social activities and travel; the unanticipated loss of a material client or key personnel; delays or reductions in client advertising budgets; shifts in industry rates of compensation; regulatory compliance costs or litigation; changes in competitive factors in the industries in which we operate and demand for our products and services; changes in client advertising, marketing and corporate communications requirements; our inability to realise the future anticipated benefits of acquisitions; failure to realise our assumptions regarding goodwill and indefinite lived intangible assets; natural disasters or acts of terrorism; the Company's ability to attract new clients; the economic and geopolitical impact of the Russian invasion of Ukraine and conflicts arising in other international markets; the risk of global economic downturn, slower growth, increasing interest rates and high and sustained inflation; supply chain issues affecting the distribution of our clients' products; technological changes and risks to the security of IT and operational infrastructure, systems, data and information resulting from increased threat of cyber and other attacks; the Company's exposure to changes in the values of other major currencies (because a substantial portion of its revenues are derived and costs incurred outside of the UK); and the overall level of economic activity in the Company's major markets (which varies depending on, among other things, regional, national and international political and economic conditions and government regulations in the world's advertising markets). In addition, you should consider the risks described in Item 3D, captioned "Risk Factors" in the Group's Annual Report on Form-20F for 2022, which could also cause actual results to differ from forward-looking information.

Neither the Company, nor any of its directors, officers or employees, provides any representation, assurance or guarantee that the occurrence of any events anticipated, expressed or implied in any forward-looking statements will actually occur. Accordingly, no assurance can be given that any particular expectation will be met and investors are cautioned not to place undue reliance on the forward-looking statements.
