“THE WORK WE DO FOR CLIENTS HELPS THEM TO GROW THEIR BUSINESSES, BUILD RELATIONSHIPS WITH THEIR CUSTOMERS AND READY THEMSELVES FOR FUTURE SUCCESS.” Mark Read Chief Executive Of?cer As technology reshapes our industry, WPP is undergoing its own transformation. I feel very proud to have been given the opportunity to lead the Company at this important moment in its development. WPP is a great business with many thousands of talented people and outstanding agency brands. We count most of the world’s biggest companies as our clients and we are the largest partner to many of the world’s leading media and technology companies. The work we do for clients helps them to grow their businesses, build relationships with their customers and ready themselves for future success. We have real scale, with strong global creative networks and the number one media-buying operation worldwide through GroupM. We are leaders in major markets like China, India and Brazil, which are important to our clients’ future growth. The amazing work produced by our people, agencies and teams is recognised around the world for its creativity and effectiveness – forging bonds with consumers and delivering tangible business results for our clients. We have a deep understanding of consumers and Chief Marketing Of?cers see us as essential partners in helping to reach them. We also have strong and growing relationships with Chief Information Of?cers and Chief Technology Of?cers, which is vital as data and technology both disrupt and create new opportunities for our clients’ businesses. See our strengths, page 39 WPP ANNUAL REPORT 2018

STRUCTURAL CHANGE, NOT STRUCTURAL DECLINE So I am an optimist about the future of WPP. I believe our industry is facing a period of structural change, not structural decline. Clients are not cutting spend; marketing expense as a share of companies’ revenue has stayed relatively constant over the last ?ve years. But spend is shifting and clients are seeking broader partnerships, well beyond our traditional strengths in commercial creativity. They want much greater insight into media channels and performance, and expertise in data. They want us to connect all of our capabilities together, and put technology at the centre of what we do. See our strategy, from page 42 We are well placed to provide everything clients need, and in a growing number of cases we already do that. However, we need to adapt more quickly to the changing world around us if we are to continue to be successful. Every industry is being disrupted by technology, and ours is no exception. New media channels have proliferated as traditional outlets have declined. Companies like Google, Facebook, Alibaba and Tencent have rede?ned the landscape. There has been an explosion in content to populate the new channels – content that needs to be produced far more cost-effectively than ever before. Ecommerce is frequently driving 100% of the growth for retailers, and our clients are looking for us to be in that space – offering everything from consultancy to the building of platforms and applications, and strategies for working with Amazon. Clients expect us to be ?uent in the language of modern, data-driven marketing. In this new environment, the role of traditional agencies is being challenged. Clients are under pressure due to changes in consumer behaviour. Consultants are becoming more signi?cant competitors. Technology companies are vying with us for talent and attention. And amidst concerns about transparency, privacy, fake news and data security, the industry needs to restore trust among the public, policymakers and clients. See our market, page 36 WPP has substantial assets to help us tackle these challenges. It is an incredible company that has built up a position as a leader in our market. But that market has changed, meaning we have to change as well to continue to deliver results for our clients. Over the years the Company became too complicated, and under-invested in key areas such as talent, creativity and technology. Consequently, WPP has under-performed its peers since the ?rst quarter of 2017, and top-line growth has been hard to ?nd. In 2018, organic growth1 was -0.4%, albeit at the upper end of the guidance we provided in October. The Company performed strongly in Western Continental Europe, Asia Paci?c, Latin America, Africa & the Middle East and Central & Eastern Europe, with the United States more challenging – something we have begun to address through our new strategy. Reported pro?t before tax was down 30.6%, re?ecting the impact of restructuring and transformation costs and goodwill impairment. Dividends per share were 60.0p, ?at with the prior year, and our year-end net debt position improved by £466 million compared to the same date in 2017 (an improvement of £605 million at 2018 exchange rates). See our ?nancial review, from page 54 RADICAL EVOLUTION: A THREE-YEAR STRATEGY To restore WPP to sustainable, pro?table growth, we have begun a three-year plan of “radical evolution” designed to improve performance across the business. We use the term “radical” because of the scale of changes we are making and the tough choices we have to take, and “evolution” because we need to take our people and clients with us on the journey. The ?rst element of the plan is clarifying our vision and offer. The way in which we present ourselves to clients and other audiences has to re?ect the nature and quality of the work we do and the creativity of the people inside WPP. This is something we spent a lot of time on during the second half on 2018 and we were pleased by how well the results were received at our investor day in December. Our vision for the new WPP is to be a “creative transformation company”. Each of those three words is important and carefully chosen. Our clients want our creativity, which is what makes us special and differentiates us from other professional services ?rms. They want us to help them transform their business in a world fundamentally changed by technology. And they want us to be a true company, to work as one on their behalf. Gone are the days when we could operate as a loose federation of independent agencies, overseen by a ?nancial holding group. As well as this new vision we articulated a new, more motivating purpose for WPP: to build better futures for our people and clients. We ?nd this resonates with people both inside and outside the Company, who are pleased to hear WPP express such a positive and con?dent reason for being. 1 Organic growth de?ned as like-for-like revenue less pass-through costs growth.

STRATEGIC REPORT CHIEF EXECUTIVE’S STATEMENT “WE REMAIN PASSIONATE ADVOCATES OF BRAND-BUILDING, ITS INCALCULABLE LONG-TERM VALUE, AND OUR CREATIVE AGENCIES’ ABILITY TO MAKE EMOTIONAL CONNECTIONS BETWEEN PEOPLE AND BRANDS THAT LAST FOR A LIFETIME.” That purpose – of building better futures – applies to our wider communities too, and in our sustainability review we talk about the many ways in which we use the power of our creativity to bring about change. See sustainability, from page 60 Our new competitive positioning was developed in consultation with our people and clients, and is supported by a refreshed brand identity – developed by two WPP companies, Superunion and Landor – that you will see reflected in the pages of this report. We are very proud of it, the feedback has been overwhelmingly positive, and I hope you feel the same way. We are also going to market with an improved, simpler offer that re?ects our clients’ needs and allows us to expand in high-growth sectors. The new offer encompasses communications, experience, commerce and technology – each of which is necessary for success for modern clients. See our offer, from page 7 The second pillar of the strategy is a renewed commitment to creativity – putting our most important competitive advantage back at the heart of the business. We are investing an additional £15 million a year for the next three years in creative leadership talent, focused on the United States, which is our largest market and where the investment is most needed. We remain passionate advocates of brand-building, its incalculable long-term value, and our creative agencies’ ability to make emotional connections between people and brands that last for a lifetime. To misquote David Ogilvy, every piece of communication – from the apparently fleeting tactical promotion to the classic “big idea” – should be approached as an investment in the future of a brand. Strong brands, especially in a market disrupted by technology, are the best protection against competitors, the best foundation for premium pricing, and the best guarantee of lasting appeal. Third, we are creating a simpler structure for WPP, to make it more straightforward for clients to access our skills and resources, and more straightforward to run. Three principles sit behind the new organisation: we will be absolutely focused on the needs of our clients in everything we do; we will have fewer, stronger companies, each positioned to grow; and we will have more closely integrated operations at the country level to make best use of our collective strengths. We have already made good progress in simplifying WPP through, for example, the creation of the integrated networks VMLY&R and Wunderman Thompson; the formation of BCW through the merger of Burson-Marsteller and Cohn & Wolfe; the alignment of our US healthcare agencies with integrated agency partners; and the elimination of the sub-holding company WPP Health & Wellness. We have also disposed of 30 non-core investments and associates, raising £849 million to reduce our debt, and accelerated our programme of co-locating our agencies in state-of-the-art new Campus buildings around the world. Fourth, we are making technology and data the engine of our business. Adopting a common strategy for the whole of WPP, we will leverage our unique technology partnerships and make our capabilities in marketing and advertising technology available to all WPP companies for the bene?t of our clients. In my ?rst months as CEO, I have spent a lot of time listening to people across the business and one of the things I heard loud and clear was a desire for WPP to make a statement about its values and the kind of culture we want to have in our Company.

CHIEF EXECUTIVE’S STATEMENT STRATEGIC REPORT “WE ARE MAKING TECHNOLOGY AND DATA THE ENGINE OF OUR BUSINESS.” Our people and clients rightly expect workplaces that are inclusive, respectful, collaborative and diverse in every sense. If we want to continue to attract the best and brightest, we have to live up to those expectations. So the ?nal part of our plan is to build and champion that new culture – one characterised by our new values of openness, optimism and a commitment to extraordinary work. More broadly, we are placing a greater emphasis on developing talent across WPP, and ensuring we have the right incentive structures for our leaders. Our new Executive Committee, drawn from agency leadership as well as from WPP central functions, will promote a new spirit of collective purpose and collaboration throughout the Company. Further details of the strategy, including the costs and associated ?nancial bene?ts of our turnaround plan, our approach to capital allocation and our new medium-term ?nancial targets, can be found from page 42 and in our investor day presentation on wpp.com. RENEWAL AND CHANGE 2018 was in many ways a turbulent and dif?cult year for WPP, for well-documented reasons. But it was also a year of renewal and much-needed change. WPP is fortunate to have a strong central team that is absolutely committed to the success of the business. We are more fortunate still to have over 130,000 brilliant colleagues in our companies around the world, each of them dedicated to professional excellence in their own discipline. Together we are building a new WPP that will deliver for our people, clients and shareholders for many years to come. Our priority in 2019 is implementing the strategy – continuing to stabilise and rejuvenate the business. Although we face headwinds from account losses in 2018, we have begun the year with con?dence after signi?cant new business wins and the positive reaction to our three-year plan. People in our business rarely have the luxury of looking backwards, and everyone at WPP has their eyes ?rmly ?xed on the future. We have every reason to look ahead with optimism about what that future will bring. Mark Read Chief Executive Of?cer 10 April 2019 WPP ANNUAL REPORT 2018

STRATEGIC REPORT OUR TO CLIENTS OFFER As announced at our investor day on 11 December 2018, our new offer comprises four areas – each of which is critical to success for modern clients. This more contemporary and future-facing offer better serves clients’ needs as they react to the changing marketplace, and expands our own business in high-growth sectors. Focuses on advertising, branding and identity, content, media investment, public relations and public affairs, and healthcare. From page 8 Re?ects the growing need of clients to create new brand, product and service experiences. From page 16 Allows WPP to expand its growing omni-channel commerce business and its work with brands to help them succeed in marketplaces such as Alibaba and Amazon. From page 22 Underpins WPP’s work with both CMOs and CIOs to build and operate marketing technology that supports their consumer- and customer-facing activities. From page 28 The areas of experience, commerce and technology already represent approximately one quarter of WPP’s revenue.

VMLY&R was given the task of creating a commercial that focused on changing the conversation of gender norms. Bumble’s agency of record, FlyteVu, secured a woman known for making bold moves on and off the court, Serena Williams, as the voice for this empowering message.

STRATEGIC REPORT OUR OFFER TO CLIENTS TECHNOLOGY PERSONALISATION AT SCALE COGNIFIDE AGENCY FORD CLIENT Ford tasked Cogni?de with the delivery of a seamless global customer experience and the capability to talk to customers individually, but at scale. The initial technical vision was to take the model of ?exible, scalable vehicle production and apply it to web development. Cogni?de created a single platform to equip all European markets with the foundation on which to build their local sites, in their own language, featuring their own vehicles, ensuring the correct speci?cation, legal compliance, consistency across all devices and a joined-up user journey across the sites. All with a globally consistent look and feel. However, web is just one channel in Ford’s mix. The greater challenge was to provide Ford with a single view of the customer across multiple channels to enable them to automatically personalise messaging at scale. Working with Adobe, Wunderman Thompson and GTB, Cogni?de achieved a world ?rst in integrating Adobe Experience Manager, Campaign, Target, Audience Manager and Analytics, stitching together the data and capability required to automate a personalised approach. This innovation, applied to a campaign targeting prospects known to be in the market for new vehicles, saw signi?cant growth in clicks to leads (test drive requests, brochure requests, contact dealer requests) and reduced cost per lead due to platform ef?ciencies. 76% 16% rise in clicks reduction in to leads cost per lead in the ?rst half in the ?rst half of 2018 of 2018 32 WPP ANNUAL REPORT 2018

STRATEGIC REPORT OUR MODEL BUSINESS WPP TRANSFORMATION IS A CREATIVE COMPANY We build better futures for our clients through an integrated offer of communications, experience, commerce and technology WPP is a creative transformation company with a service offering that allows us to meet the present and future needs of our clients. Our business model is client-centric, and we leverage resource and skills across our internal structures to provide the best possible service. WPP works with 369 of the Fortune Global 500, all 30 of the Dow Jones 30, and 71 of the NASDAQ 100. We are committed to the principles of sustainability in business, through our assignments for clients, our substantial pro bono work and the management of our own operations. We aim to build better futures not only for our people and clients but our wider communities. Our networks and agencies operate in all major global markets, offering a range of services across four key areas: communications, experience, commerce and technology. Each of these areas is critical to success for modern clients. By bringing them together WPP can meet clients’ needs as they react to the changing marketplace and complex social, economic, and environmental pressures, while expanding our own business in high-growth sectors. Revenues are principally derived from fees for services on a rate per hour or per project basis. Client engagements include ?xed-fee contracts, retainer agreements and commissions on media placements. Some client arrangements include performance incentive provisions designed to link revenue to quantitative and qualitative goals. We focus on revenue less pass-through costs as a re?ection of top-line performance. Pass-through costs comprise fees paid to external suppliers where they are engaged to perform part or all of a speci?c project and are charged directly to clients – predominantly media and data collection costs. Our people are our most important assets and our ability to attract and retain diverse talent is a critical element of our competitiveness. Compensation and incentives are aimed at making WPP a home for the best and brightest, and are aligned with our strategy for growth. Our delivery model is based on an increasingly ?exible cost structure, with the use of consultants, freelancers and incentives allowing an agile response to any market volatility. Our transformation programme, encompassing a new vision and offer, a simpli?ed structure including a consistent shared service infrastructure and the development of Campus co-locations, investments in creativity, technology and talent, and a new emphasis on building the Company’s culture, will enhance WPP’s proposition to clients and drive top-line growth. 40 WPP ANNUAL REPORT 2018

FINANCIAL REVIEW STRATEGIC REPORT BUSINESS SECTOR REVIEW The pattern of revenue and revenue less pass-through costs growth also varied by sector and operating brand. The tables opposite give further details. Advertising and Media Investment Management In constant currencies, advertising and media investment management revenue less pass-through costs was down 1.6% in the fourth quarter, a signi?cant improvement on the -6.5% in the third quarter and the strongest quarter of the year. On a like-for-like basis revenue less pass-through costs was up 0.4% in the fourth quarter, the ?rst quarter of positive growth, with both our advertising and media investment businesses showing considerable improvement over the third quarter. However, despite this improvement, our advertising businesses remain under pressure. The strong revenue less pass-through costs growth across most of the Group’s media investment management businesses, offset by slower growth in our advertising businesses in most regions, resulted in the combined reported operating margin of this sector being down 1.2 margin points at 17.6% and down 1.4 margin points in constant currency.

SUSTAINABILITY STRATEGIC REPORT HOW GOOD MARKETING MAKES FOR BETTER DEMOCRACY MULTI-AGENCY AGENCY TEAM LED BY GREY LONDON UNITED CLIENT NATIONS DPI AND UNFCCC In an age of growing grassroots activism, many people feel that action happens on the street, not behind the closed doors of the United Nations. We brought together a multi-agency team, led by Grey London, to help the UN reconnect with the world’s people and put them back at the centre of their work. The team put a new People’s Seat in the UN plenary, right among world leaders. It was the ?rst seat in UN history not representing a nation or speci?c interest. Instead it was there to give the world a voice on climate change. The campaign asked people around the world to express their thoughts, fears and experiences of climate change. These testimonials were crafted into a UN address delivered by Sir David Attenborough to key leaders poised to negotiate one of the most important decisions in the history of our planet. The speech dominated the global news agenda, reaching some 1.3 billion people and ensuring the climate talks made headlines in countries including the UK, US and China.

FINANCIAL STATEMENTS ACCOUNTING POLICIES FINANCE LEASES Assets held under finance leases are recognised as assets of the Group at the inception of the lease at the lower of their fair value and the present value of the minimum lease payments. Depreciation on leased assets is charged to the consolidated income statement on the same basis as owned assets. Leasing payments are treated as consisting of capital and interest elements and the interest is charged to the consolidated income statement as it is incurred. OPERATING LEASES Operating lease rentals are charged to the consolidated income statement on a straight-line basis over the lease term. Any premium or discount on the acquisition of a lease is spread over the life of the lease on a straight-line basis. TRANSLATION OF FOREIGN CURRENCIES Foreign currency transactions arising from normal trading activities are recorded at the rates in effect at the date of the transaction. Monetary assets and liabilities denominated in foreign currencies at the year-end are translated at the year-end exchange rate. Foreign currency gains and losses are credited or charged to the consolidated income statement as they arise. The income statements of overseas subsidiary undertakings are translated into pounds sterling at average exchange rates and the year-end net assets of these companies are translated at year-end exchange rates. Exchange differences arising from retranslation of the opening net assets and on foreign currency borrowings (to the extent that they hedge the Group’s investment in such operations) are reported in the consolidated statement of comprehensive income. Goodwill and fair value adjustments arising on the acquisition of a foreign entity are treated as assets and liabilities of the foreign entity and translated at the closing rate. HYPERINFLATION IN ARGENTINA During 2018, Argentina was designated as a hyperinflationary economy and the financial statements of the Group’s subsidiaries in Argentina have been adjusted for the effects of inflation in accordance with IAS 29 Financial Reporting in Hyperinflationary Economies. IAS 29 requires that the income statement is adjusted for inflation in the period and translated at the year-end foreign exchange rate and that non-monetary assets and liabilities on the balance sheet are restated to reflect the change in purchasing power caused by inflation from the date of initial recognition. This resulted in an increase in goodwill of £105.8 million and an increase in other intangibles of £19.5 million. The impact on other non-monetary assets and liabilities and the impact on the Group’s income statement in the year were immaterial. SHARE-BASED PAYMENTS The Group issues equity-settled share-based payments (including share options) to certain employees and accounts for these awards in accordance with IFRS 2 Share-Based Payment. Equity-settled share-based payments are measured at fair value (excluding the effect of non-market-based vesting conditions) at the date of grant. Details regarding the fair value of equity settled share-based transactions are set out in notes 21 and 25. The fair value determined at the grant date is recognised in the consolidated income statement as an expense on a straight-line basis over the relevant vesting period, based on the Group’s estimate of the number of shares that will ultimately vest and adjusted for the effect of non-market-based vesting conditions. CRITICAL JUDGEMENTS AND ESTIMATION UNCERTAINTY IN APPLYING ACCOUNTING POLICIES Management is required to make key decisions and judgements whilst acknowledging there is estimation uncertainty in the process of applying the Group’s accounting policies. These estimates and judgements are reviewed on an ongoing basis. Where judgement has been applied or estimation uncertainty exists, the key factors taken into consideration are disclosed in the accounting policies and the appropriate note in these financial statements. The most significant areas of estimation uncertainty include: – Goodwill: The discounted cash flow methodology employed by the Group when testing for goodwill impairment requires estimates regarding revenue growth, operating margins, discount rates and working capital requirements. Further details of the methodology, discount rates, long-term growth rates and estimates used in relation to the goodwill impairment on VMLY&R in 2018 are set out in note 12. – Payments due to vendors (earnout agreements) and liabilities in respect of put options: Estimates are required regarding growth rates in deriving future financial performance and discount rates to be applied when measuring the liabilities for earnouts and put options. Further details on growth rates and discount rates and the sensitivity to these estimates are set out in note 24. – Provision for post-employment benefits: Estimates are required in the accounting for defined benefit pension plans, including establishing discount rates, rates of increase in salaries and pensions in payment, inflation and mortality assumptions. These estimates are made by management based on the advice of qualified advisors. Details of the assumptions used and the sensitivity of the benefit obligation to these assumptions are set out in note 22. The most significant areas of judgements include: – Revenue recognition: Judgement is required regarding the timing of recognition, particularly in relation to media volume income with regards to whether it is required to be passed back to the client and in assessing progress on performance obligations where revenue is recognised over time, particularly in the Group’s Data Investment Management business. Further details are set out in the accounting policy. – Taxation: Judgement is required in relation to the level of provisions required and the amount of taxes that will be due, particularly given the many countries in which the Group operates. Where the final tax outcome is different from the amounts recorded then such differences may expose the Group to additional tax liabilities or impact the carrying value of deferred tax assets, which would affect the future tax charge. Further details are set out in note 7.

FINANCIAL STATEMENTS NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS FOR THE YEAR ENDED 31 DECEMBER 2018 1. GENERAL INFORMATION WPP plc is a company incorporated in Jersey.

The nature of the Group’s operations and its principal activities are set out in note 2. These consolidated financial statements are presented in pounds sterling. 2. SEGMENT INFORMATION The Group is a leading worldwide creative transformation organisation offering national and multinational clients a comprehensive range of communications, experience, commerce and technology services. Substantially all of the Group’s revenue is from contracts with customers. The Group is organised into four reportable segments – Advertising and Media Investment Management; Data Investment Management; Public Relations & Public Affairs; and Brand Consulting, Health & Wellness and Specialist Communications. This last reportable segment includes direct, interactive and ecommerce. IFRS 8 Operating Segments requires operating segments to be identified on the same basis as is used internally for the review of performance and allocation of resources by the Chief Executive Officer. Provided certain quantitative and qualitative criteria are fulfilled, IFRS 8 permits the aggregation of these components into reportable segments for the purposes of disclosure in the Group’s financial statements. In assessing the Group’s reportable segments, the Directors have had regard to the similar economic characteristics of certain operating segments, their shared client base, the similar nature of their products or services and their long-term margins, amongst other factors.

The goodwill impairment charge of £183.9 million (2017: £27.1 million, 2016: £27.0 million) primarily relates to a charge of £148.0 million on VMLY&R, with the remaining £35.9 million relating to a number of under-performing businesses in the Group.

In 2017, the market value of comScore Inc fell below the Group’s carrying value. Other investment write-downs relate to certain non-core minority investments in the US where forecast financial performance and/or liquidity issues indicate a permanent decline in the recoverability of the Group’s investment.

The majority of the Group’s long-term debt is represented by $2,784 million of US dollar bonds at an average interest rate of 4.46%, €3,700 million of Eurobonds at an average interest rate of 1.64% and £600 million of Sterling bonds at an average interest rate of 4.04%. Average borrowings under the US Dollar Revolving Credit Facilities (note 10) amounted to the equivalent of $125 million at an average interest rate of 0.96% (2017: $715 million at an average interest rate of 0.78%). Average borrowings under the Australian dollar Revolving Credit Facilities, amounted to A$439 million at an average rate of 3.27% (2017: A$412 million at an average rate of 3.24%). Average borrowings under the US Commercial Paper Programme for 2018 amounted to $540 million at an average interest rate of 2.28% inclusive of margin (2017: $860 million at an average interest rate of 1.47% inclusive of margin). 7. TAXATION The tax rate on reported profit before tax was 22.1% (2017: 9.3%, 2016: 20.6%). The headline tax rate was 22.5% (2017: 22.0%, 2016: 21.0%). The cash tax rate on headline PBT was 20.6% (2017: 20.3%, 2016: 20.9%). On 22 December 2017, The Tax Cuts and Jobs Act was enacted in the US which reduced the federal tax rate from 35% to 21% from 1 January 2018. As a result, deferred tax assets and liabilities were remeasured at the end of 2017, leading to a non-cash credit to the income statement of £234.1 million, partially offset by a one-time deemed repatriation tax charge related to unremitted foreign earnings of £28.1 million, payable over eight years. The impact of US tax reform has been excluded from the headline tax charge. The tax charge comprises: 2018 2017 2016 £m £m £m Corporation tax Current year 481.9 523.4 569.4 Prior years (111.8) (98.6) (80.3) 370.1 424.8 489.1 Deferred tax Current year (49.0) (235.2) (88.0) Prior years 2.8 7.4 (12.2) (46.2) (227.8) (100.2) Tax charge 323.9 197.0 388.9 The corporation tax credit for prior years in 2018, 2017 and 2016, mainly comprises the release of a number of provisions following the resolution of tax matters in various countries. The tax charge for the year can be reconciled to profit before taxation in the consolidated income statement as follows: 2018 2017 2016 £m £m £m Pro?t before taxation 1,463.3 2,109.3 1,890.5 Tax at the corporation tax rate of 19.0%1 278.0 406.0 378.1 Tax effect of share of results of associates (8.3) (21.8) (10.0) Irrecoverable withholding taxes 55.9 37.0 36.3 Items in determining that are not taxable deductible/(taxable) pro?t 28.7 (3.9) 9.4 Effect in other of jurisdictions different tax rates in subsidiaries operating 90.2 140.3 60.4 US foreign Transition earnings Tax related to unremitted (7.3) 28.1 –Effect balances of change in US tax rate on deferred tax – (234.1) –Origination differences and reversal of unrecognised temporary 7.5 (17.2) (4.3) Tax losses not recognised or utilised in the year 22.3 32.5 52.2 Utilisation of tax losses not previously recognised (25.6) (10.4) (11.3) Recognition not previously of recognised temporary differences (8.4) (68.3) (29.4) Net in relation release to of acquired prior year businesses provisions (20.4) (15.0) (23.3) Other prior year adjustments (88.7) (76.2) (69.2) Tax charge 323.9 197.0 388.9 Effective tax rate on pro?t before tax 22.1% 9.3% 20.6% Note 1 The Parent Company of the Group is tax resident in the UK. As the Group is subject to the tax rates of more than one country, it has chosen to present its reconciliation of the tax charge using the UK corporation tax rate of 19% (2017: 19.25%, 2016: 20%). The headline tax charge excludes the impact of items that are excluded from headline PBT and excludes the deferred tax impact of the amortisation of acquired intangible assets and other goodwill items as these will only reverse in the event of future disposals of those assets, in which case any accounting gain or loss would be excluded from headline profits. The impact of the Tax Cuts and Jobs Act has also been excluded from the headline tax charge. 136 WPP ANNUAL REPORT 2018

FACTORS AFFECTING THE TAX CHARGE IN FUTURE YEARS Given the Group’s geographic mix of profits and the changing international tax environment, the tax rate is expected to increase slightly over the next few years. Factors that may affect the Group’s future tax charge include the levels and mix of profits in the many countries in which we operate, the prevailing tax rates in each of those countries and also the foreign exchange rates that apply to those profits. The tax charge may also be affected by the impact of acquisitions, disposals and other corporate restructurings, the resolution of open tax issues, future planning, and the ability to use brought forward tax losses. Furthermore, changes in local or international tax rules, for example prompted by the OECD’s Base Erosion and Profit Shifting project (a global initiative to improve the fairness and integrity of tax systems), or new challenges by tax or competition authorities, for example, the European Commission’s state aid investigation into Group Financing Exemption in the UK CFC rules announced in October 2017, may expose us to additional tax liabilities or impact the carrying value of our deferred tax assets, which would affect the future tax charge. The Group has a number of open tax returns and various ongoing tax audits worldwide but does not currently expect material additional tax exposures to arise, above the amounts provided, as and when the audits are concluded. Liabilities relating to these open and judgemental matters are based upon estimates of whether additional taxes will be due after taking into account external advice where appropriate. Where the final tax outcome of these matters is different from the amounts which were initially recorded then such differences will impact the current and deferred income tax assets and liabilities in the period in which such determination is made. TAX RISK MANAGEMENT We maintain constructive engagement with the tax authorities and relevant government representatives, as well as active engagement with a wide range of international companies and business organisations with similar issues. We engage advisors and legal counsel to obtain opinions on tax legislation and principles. We have a Tax Risk Management Strategy in place which sets out the controls established and our assessment procedures for decision-making and how we monitor tax risk. We monitor proposed changes in taxation legislation and ensure these are taken into account when we consider our future business plans. Our Directors are informed by management of any tax law changes, the nature and status of any significant ongoing tax audits, and other developments that could materially affect the Group’s tax position. 8.

At 31 December 2018, options to purchase 16.9 million ordinary shares (2017: 8.2 million, 2016: 8.4 million) were outstanding, but were excluded from the computation of diluted earnings per share because the exercise prices of these options were greater than the average market price of the Group’s shares and, therefore, their inclusion would have been accretive.

Brands with an indefinite life are carried at historical cost in accordance with the Group’s accounting policy for intangible assets. The carrying values of the separately identifiable brands are not individually significant in comparison with the total carrying value of brands with an indefinite useful life. Acquired intangible assets at net book value at 31 December 2018 include brand names of £361.2 million (2017: £445.6 million), customer-related intangibles of £220.6 million (2017: £360.9 million), and other assets (including proprietary tools) of £13.0 million (2017: £22.6 million). The total amortisation and impairment of acquired intangible assets of £280.0 million (2017: £195.1 million) includes an impairment charge of £126.1 million (2017: £6.0 million) comprising £58.6 million in regard to certain brand names that are no longer in use and £67.5 million in regard to customer relationships where the underlying clients have been lost. £70.6 million of the impairment charge relates to the Advertising and Media Investment Management segment, £38.2 million relates to the Data Investment Management segment, and £17.3 million relates to the Brand Consulting, Health & Wellness and Specialist Communications segment. In addition, the total amortisation and impairment of acquired intangible assets includes £4.2 million (2017: £5.7 million) in relation to associates. In accordance with the Group’s accounting policy, the carrying values of goodwill and intangible assets with indefinite useful lives are reviewed for impairment annually or more frequently if events or changes in circumstances indicate that the asset might be impaired. 140 WPP ANNUAL REPORT 2018

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS FINANCIAL STATEMENTS The impairment review is undertaken annually on 30 September. The review assessed whether the carrying value of goodwill and intangible assets with indefinite useful lives was supported by the net present value of future cash flows, using a pre-tax discount rate of 9.0% (2017: 8.5%) and management forecasts for a projection period of up to five years, followed by an assumed annual long-term growth rate of 3.0% (2017: 3.0%) and no assumed improvement in operating margin. Management have made the judgement that this long-term growth rate does not exceed the long-term average growth rate for the industry. The goodwill impairment charge of £183.9 million (2017: £27.1 million) primarily relates to a charge of £148.0 million on VMLY&R, driven by challenges in the advertising businesses in the Advertising and Media Investment Management segment. The recoverable amount for the VMLY&R cash-generating unit is £1,327.3 million. It is based on a value in use calculation, assuming a pre-tax discount rate of 8.7% specific to VMLY&R. A pre-tax discount rate of 8.5% was used in the prior year. The cash-generating unit includes goodwill, intangible assets, and other assets. The remaining £35.9 million relates to a number of under-performing businesses in the Group. In certain markets, the impact of local economic conditions and trading circumstances on these businesses was sufficiently severe to indicate impairment to the carrying value of goodwill. The VMLY&R impairment review is sensitive to changes in the assumptions used, most notably to changes in the discount rate, terminal growth rate and terminal margin. A summary of the movements in the impairment charge from a change in these assumptions is as follows: – 0.1% movement in the discount rate would increase or decrease the impairment charge by £23 million; – 0.1% movement in the terminal growth rate would increase or decrease the impairment charge by £19 million; and – 0.1% movement in terminal margin would increase or decrease the impairment charge by £8 million. Under IFRS, an impairment charge is required for both goodwill and other indefinite-lived assets when the carrying amount exceeds the ‘recoverable amount’, defined as the higher of fair value less costs to sell and value in use. Our approach in determining the recoverable amount utilises a discounted cash flow methodology, which necessarily involves making numerous estimates and assumptions regarding revenue growth, operating margins, appropriate discount rates and working capital requirements. The key assumptions used for estimating cash flow projections in the Group’s impairment testing are those relating to revenue growth and operating margin. The key assumptions take account of the businesses’ expectations for the projection period. These expectations consider the macroeconomic environment, industry and market conditions, the unit’s historical performance and any other circumstances particular to the unit, such as business strategy and client mix. These estimates will likely differ from future actual results of operations and cash flows, and it is possible that these differences could be material. In addition, judgements are applied in determining the level of cash-generating unit identified for impairment testing and the criteria used to determine which assets should be aggregated. A difference in testing levels could affect whether an impairment is recorded and the extent of impairment loss. For the 2018 impairment review, certain assets previously aggregated with the VMLY&R cash-generating unit have been realigned to other cash-generating units as part of the overall effort to simplify operations and become more client-centric. Changes in our business activities or structure may also result in additional changes to the level of testing in future periods. Further, future events could cause the Group to conclude that impairment indicators exist and that the asset values associated with a given operation have become impaired. Any resulting impairment loss could have a material impact on the Group’s financial condition and results of operations. Historically our impairment losses have resulted from a specific event, condition or circumstance in one of our companies, such as the loss of a significant client. As a result, changes in the assumptions used in our impairment model have not had a significant effect on the impairment charges recognised and a reasonably possible change in assumptions would not lead to a significant impairment, except for VMLY&R as discussed above. The carrying value of goodwill and other intangible assets will continue to be reviewed at least annually for impairment and adjusted down to the recoverable amount if required. 13.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS FINANCIAL STATEMENTS 15. DEFERRED TAX The Group’s deferred tax assets and liabilities are measured at the end of each period in accordance with IAS 12 Income taxes. The recognition of deferred tax assets is determined by reference to the Group’s estimate of recoverability, using models where appropriate to forecast future taxable profits. Deferred tax assets have only been recognised for territories where the Group considers that it is probable that all or a portion of the deferred tax assets will be realised. The main factors that we consider include: – the future earnings potential determined through the use of internal – the history of losses carried forward and other tax assets expiring; forecasts; – the timing of future reversal of taxable temporary differences; – the cumulative losses in recent years; – the expiry period associated with the deferred tax assets; and – the various jurisdictions in which the potential deferred tax assets arise; – the nature of the income that can be used to realise the deferred tax asset. If it is probable that some portion of these assets will not be realised, then no asset is recognised in relation to that portion. If market conditions improve and future results of operations exceed our current expectations, our existing recognised deferred tax assets may be adjusted, resulting in future tax benefits. Alternatively, if market conditions deteriorate further or future results of operations are less than expected, future assessments may result in a determination that some or all of the deferred tax assets are not realisable. As a result, all or a portion of the deferred tax assets may need to be reversed. Certain deferred tax assets and liabilities have been offset as they relate to the same tax group. The following is the analysis of the deferred tax balances for financial reporting purposes: As As Gross Offset reported Gross Offset reported 2018 2018 2018 2017 2017 2017 £m £m £m £m £m £m Deferred tax assets 412.0 (259.0) 153.0 411.8 (251.5) 160.3 Deferred tax liabilities (738.5) 259.0 (479.5) (765.2) 251.5 (513.7) (326.5) – (326.5) (353.4) – (353.4) The following are the major gross deferred tax assets recognised by the Group and movements thereon in 2018 and 2017: Accounting Retirement Property, Other Deferred provisions bene?t plant and Tax losses Share-based Restructuring temporary compensation and accruals obligations equipment and credits payments provisions differences Total £m £m £m £m £m £m £m £m £m 1 January 2017 95.6 80.6 141.4 70.8 89.7 75.8 5.9 38.2 598.0 Acquisition of subsidiaries – – – – – – – 2.6 2.6 (Charge)/credit to income (5.5) 6.6 (10.2) 6.9 (34.4) (0.4) (1.5) (21.7) (60.2) Impact of US tax reform (30.8) (8.1) (29.1) (6.8) 23.1 (10.9) 1.6 (1.1) (62.1) Charge to other comprehensive income – – (20.9) – – – – – (20.9) Charge to equity – – – – – (27.3) – – (27.3) Exchange differences (5.8) 5.8 (5.6) (2.5) (5.7) (4.2) (0.2) (0.1) (18.3) 31 December 2017 53.5 84.9 75.6 68.4 72.7 33.0 5.8 17.9 411.8 Acquisition of subsidiaries – – – – – – – 2.0 2.0 Credit/(charge) to income 4.7 13.0 (11.2) (20.6) (8.9) (15.3) 10.7 11.0 (16.6) Charge to other comprehensive income – – (0.2) – – – – – (0.2) Charge to equity – – – – – (1.6) – – (1.6) Exchange differences 3.4 3.5 4.3 0.1 3.3 0.7 0.8 0.5 16.6 31 December 2018 61.6 101.4 68.5 47.9 67.1 16.8 17.3 31.4 412.0 Other temporary differences comprise a number of items including tax deductible goodwill, none of which is individually significant to the Group’s consolidated balance sheet.

Deferred tax assets have been recognised in respect of the tax benefit of £1,763.4 million (2017: £1,539.3 million) of such tax losses and other temporary differences. No deferred tax asset has been recognised in respect of the remaining £4,875.2 million (2017: £4,669.3 million) of losses and other temporary differences as the Group considers that there will not be enough taxable profits in the entities concerned such that any additional asset could be considered recoverable. Included in the total unrecognised temporary differences are losses of £46.4 million (2017: £56.5 million) that will expire within 1–10 years, and £4,572.6 million (2017: £4,421.5 million) of losses that may be carried forward indefinitely. At the balance sheet date, the aggregate amount of the temporary differences in relation to the investment in subsidiaries for which deferred tax liabilities have not been recognised was £1,768.5 million (2017: £3,898.0 million). No liability has been recognised in respect of these differences because the Group is in a position to control the timing of the reversal of the temporary differences and the Group considers that it is probable that such differences will not reverse in the foreseeable future. 16.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS FINANCIAL STATEMENTS The Group has applied the practical expedient permitted by IFRS 15 to not disclose the transaction price allocated to performance obligations unsatisfied (or partially unsatisfied) as of the end of the reporting period as contracts typically have an original expected duration of a year or less. Bad debt provisions: 2018 2017 £m £m At beginning of year 91.3 93.8 New acquisitions 1.5 1.2 Charged to the income statement 66.7 27.4 Released to the income statement (11.6) (8.4) Exchange adjustments 2.1 (4.1) Utilisations and other movements (33.4) (18.6) At end of year 116.6 91.3 The allowance for bad and doubtful debts is equivalent to 1.4% (2017: 1.1%) of gross trade accounts receivables. The requirement to use an expected loss method of impairment of financial assets on adoption of IFRS 9 on 1 January 2018 did not have a material impact on the Group. The Group has applied the simplified approach to measuring expected credit losses, as permitted by IFRS 9, and recognises a loss allowance based on the financial asset’s lifetime expected credit loss. Based on the aging of the invoice, the loss allowance at 31 December 2018 and 1 January 2018 (on adoption of IFRS 9) is as follows: 0-90 91-180 181 days- Over days days 1 year 1 year 31 December 2018 £m £m £m £m £m Gross trade receivables 8,178.9 7,621.9 381.5 86.5 89.0 Loss allowance 116.6 11.3 3.8 39.2 62.3 Expected loss rate 1.4% 0.1% 1.0% 45.3% 70.0% 0-90 91-180 181 days- Over days days 1 year 1 year 1 January 2018 £m £m £m £m £m Gross trade receivables 7,981.0 7,392.6 425.6 78.6 84.2 Loss allowance 91.3 2.9 2.8 24.2 61.4 Expected loss rate 1.1% 0.0% 0.7% 30.8% 73.0% Impairment losses on work in progress and accrued income were immaterial for the years presented. The Group considers that the carrying amount of trade and other receivables approximates their fair value. 17.

The Company and various of its subsidiaries are, from time to time, parties to legal proceedings and claims which arise in the ordinary course of business. The Directors do not anticipate that the outcome of these proceedings and claims will have a material adverse effect on the Group’s financial position or on the results of its operations. 21. SHARE-BASED PAYMENTS Charges for share-based incentive plans were as follows: 2018 2017 2016 £m £m £m Share-based payments (note 5) 84.8 105.0 106.5 Share-based payments comprise charges for stock options and restricted stock awards to employees of the Group. As of 31 December 2018, there was £146.0 million (2017: £156.0 million) of total unrecognised compensation cost related to the Group’s restricted stock plans. That cost is expected to be recognised over an average period of one to two years. Further information on stock options is provided in note 25. RESTRICTED STOCK PLANS The Group operates a number of equity-settled share incentive schemes, in most cases satisfied by the delivery of stock from one of the Group’s ESOP Trusts. The most significant current schemes are as follows: EXECUTIVE PERFORMANCE SHARE PLAN (EPSP) This scheme is intended to reward and incentivise the most senior executives of the Group. The performance period is five complete financial years, commencing with the financial year in which the award is granted. The vest date will usually be in the March following the end of the five-year performance period. Vesting is conditional on continued employment throughout the vesting period. There are three performance criteria, each constituting one-third of the vesting value, and each measured over this five-year period: (i) TSR against a comparator group of companies. Threshold performance (equating to ranking in the 50th percentile of the comparator group) will result in 20% vesting of the part of the award dependent on TSR. The maximum vest of 100% will arise if performance ranks in the 90th percentile, with a sliding scale of vesting for performance between threshold and maximum. (ii) Headline diluted earnings per share. Threshold performance (7% compound annual growth) will again result in a 20% vest. Maximum performance of 14% compound annual growth will give rise to a 100% vest, with a sliding vesting scale for performance between threshold and maximum. (iii) Return on equity (ROE). Average annual ROE defined as headline diluted EPS divided by the balance sheet value per share of shareholders’ equity. Threshold performance ranges between 10–14% average annual ROE and maximum performance ranges between 14–18%, with a sliding scale in between. Threshold again gives rise to a 20% vest, 100% for maximum, with a sliding scale in between. PERFORMANCE SHARE AWARDS (PSA) Grants of restricted stock under PSA are dependent upon annual performance targets, typically based on one or more of: operating profit, profit before taxation and operating margin. Grants are made in the year following the year of performance measurement, and vest two years after grant date provided the individual concerned is continually employed by the Group throughout this time. LEADERS, PARTNERS AND HIGH POTENTIAL GROUP This scheme provides annual grants of restricted stock to approximately 1,800 key executives of the Group. Vesting is conditional on continued employment over the three-year vesting period. VALUATION METHODOLOGY For all of these schemes, the valuation methodology is based upon fair value on grant date, which is determined by the market price on that date or the application of a Black-Scholes model, depending upon the characteristics of the scheme concerned. The assumptions underlying the Black-Scholes model are detailed in note 25, including details of assumed dividend yields. Market price on any given day is obtained from external, publicly available sources. MARKET/NON-MARKET CONDITIONS Most share-based plans are subject to non-market performance conditions, such as margin or growth targets, as well as continued employment. EPSP is subject to a number of performance conditions, including TSR, a market-based condition. For schemes without market-based performance conditions, the valuation methodology above is applied and, at each year-end, the relevant accrual for each grant is revised, if appropriate, to take account of any changes in estimate of the likely number of shares expected to vest. For schemes with market-based performance conditions, the probability of satisfying these conditions is assessed at grant date through a statistical model (such as the Monte Carlo Model) and applied to the fair value. This initial valuation remains fixed throughout the life of the relevant plan, irrespective of the actual outcome in terms of performance. Where a lapse occurs due to cessation of employment, the cumulative charge taken to date is reversed. 146 WPP ANNUAL REPORT 2018

PROVISION FOR POST-EMPLOYMENT BENEFITS Companies within the Group operate a large number of pension plans, the forms and benefits of which vary with conditions and practices in the countries concerned. The Group’s pension costs are analysed as follows: 2018 2017 2016 £m £m £m De?ned contribution plans 172.3 175.9 153.5 De?ned bene?t plans charge to operating pro?t 18.9 16.1 24.6 Pension costs (note 5) 191.2 192.0 178.1 Net interest expense on pension plans (note 6) 4.4 6.3 6.7 195.6 198.3 184.8 DEFINED BENEFIT PLANS The pension costs are assessed in accordance with the advice of local independent qualified actuaries. The latest full actuarial valuations for the various pension plans were carried out at various dates in the last three years. These valuations have been updated by the local actuaries to 31 December 2018. The Group’s policy is to close existing defined benefit plans to new members. This has been implemented across a significant number of the pension plans. Contributions to funded plans are determined in line with local conditions and practices. Contributions in respect of unfunded plans are paid as they fall due. The total contributions (for funded plans) and benefit payments (for unfunded plans) paid for 2018 amounted to £44.9 million (2017: £68.2 million, 2016: £43.7 million). Employer contributions and benefit payments in 2019 are expected to be approximately £50 million. (A) ASSUMPTIONS There are a number of areas in pension accounting that involve estimates made by management based on advice of qualified advisors. These include establishing the discount rates, rates of increase in salaries and pensions in payment, inflation, and mortality assumptions. The main weighted average assumptions used for the actuarial valuations at 31 December are shown in the following table: 2018 2017 2016 2015 % pa % pa % pa % pa UK Discount rate1 2.8 2.4 2.5 3.7 Rate of increase in salaries2 n/a n/a 3.5 3.1 Rate of increase in pensions in payment 4.3 4.1 4.1 3.9 In?ation 2.8 2.7 2.8 2.4 North America Discount rate1 4.1 3.5 3.8 4.0 Rate of increase in salaries 3.0 3.1 3.1 3.0 In?ation n/a 4.0 4.0 2.5 Western Continental Europe Discount rate1 2.0 1.9 1.7 2.5 Rate of increase in salaries 2.3 1.9 2.0 2.3 Rate of increase in pensions in payment 1.2 1.2 1.3 1.6 In?ation 1.7 1.7 1.7 2.0 Asia Middle Paci?c, East and Latin Central America, & Eastern Africa & Europe Discount rate1 5.0 4.2 4.2 4.2 Rate of increase in salaries 5.8 5.5 5.9 5.8 In?ation 3.6 4.0 4.0 4.0 Notes 1 Discount rates are based on high-quality corporate bond yields. In countries where there is no deep market in corporate bonds, the discount rate assumption has been set with regard to the yield on long-term government bonds. 2 The salary assumptions are no longer applicable to the UK as all plans were frozen since 2017. Active participants will not accrue additional bene?ts for future services under these plans. For the Group’s pension plans, the plans’ assets are invested with the objective of being able to meet current and future benefit payment needs, while controlling balance sheet volatility and future contributions. Pension plan assets are invested with a number of investment managers, and assets are diversified among equities, bonds, insured annuities, property and cash or other liquid investments. The primary use of bonds as an investment class is to match the anticipated cash flows from the plans to pay pensions. The Group is invested in high-quality corporate and government bonds which share similar risk characteristics and are of equivalent currency and term to the plan liabilities. Various insurance policies have also been bought historically to provide a more exact match for the cash flows, including a match for the actual mortality of specific plan members. These insurance policies effectively provide protection against both investment fluctuations and longevity risks. The strategic target allocation varies among the individual plans. Management considers the types of investment classes in which the pension plan assets are invested. The types of investment classes are determined by economic and market conditions and in consideration of specific asset class risk. Management periodically commissions detailed asset and liability studies performed by third-party professional investment advisors and actuaries that generate probability-adjusted expected future returns on those assets. These studies also project the estimated future pension payments and evaluate the efficiency of the allocation of the pension plan assets into various investment categories.

FINANCIAL STATEMENTS NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS At 31 December 2018, the life expectancies underlying the value of the accrued liabilities for the main defined benefit pension plans operated by the Group were as follows: Western All North Continental Years life expectancy after age 65 plans America UK Europe Other1 – (at current age 65) pensioners – male 22.2 22.1 23.2 21.1 17.0 – (at current age 65) pensioners – female 23.9 23.6 24.3 24.0 21.4 – (current future pensioners age 45) – male 24.0 23.7 24.8 23.5 17.0 – future (current pensioners age 45) – female 25.7 25.2 26.1 26.2 21.4 Note 1 Includes Asia Paci?c, Latin America, Africa & Middle East and Central & Eastern Europe. The life expectancies after age 65 at 31 December 2017 were 22.4 years and 24.0 years for male and female current pensioners (at age 65), respectively, and 23.8 years and 25.7 years for male and female future pensioners (current age 45), respectively. In the determination of mortality assumptions, management uses the most up-to-date mortality tables available in each country. The following table provides information on the weighted average duration of the defined benefit pension obligations and the distribution of the timing of benefit payments for the next 10 years. The duration corresponds to the weighted average length of the underlying cash flows.

The following table presents a sensitivity analysis for each significant actuarial assumption showing how the defined benefit obligation would have been affected by changes in the relevant actuarial assumption that were reasonably possible at the balance sheet date. This sensitivity analysis applies to the defined benefit obligation only and not to the net defined benefit pension liability in its entirety, the measurement of which is driven by a number of factors including, in addition to the assumptions below, the fair value of plan assets. The sensitivity analyses are based on a change in one assumption while holding all other assumptions constant so that interdependencies between the assumptions are excluded. The methodology applied is consistent with that used to determine the recognised defined benefit obligation. The sensitivity analysis for inflation is not shown as it is an underlying assumption to build the pension and salary increase assumptions. Changing the inflation assumption on its own without changing the salary or pension assumptions will not result in a significant change in pension liabilities.

FOREIGN CURRENCY RISK The Group’s results in pounds sterling are subject to fluctuation as a result of exchange rate movements. The Group does not hedge this translation exposure to its earnings but does hedge the currency element of its net assets using foreign currency borrowings, cross-currency swaps and forward foreign exchange contracts. The Group effects these currency net asset hedges by borrowing in the same currencies as the operating (or ‘functional’) currencies of its main operating units. The majority of the Group’s debt is therefore denominated in US dollars, pounds sterling and euros. The Group’s borrowings at 31 December 2018 were primarily made up of $2,784 million, £1,044 million and €3,200 million (2017: $3,931 million, £600 million and €3,202 million). The Group’s average gross debt during the course of 2018 was $3,377 million, £1,039 million and €3,202 million (2017: $3,741 million, £1,242 million and €3,108 million). The Group’s operations conduct the majority of their activities in their own local currency and consequently the Group has no significant transactional foreign exchange exposures arising from its operations. Any significant cross-border trading exposures are hedged by the use of forward foreign-exchange contracts. No speculative foreign exchange trading is undertaken. WPP ANNUAL REPORT 2018 149

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS FINANCIAL STATEMENTS SENSITIVITY ANALYSIS The following sensitivity analysis addresses the effect of currency and interest rate risks on the Group’s financial instruments. The analysis assumes that all hedges are highly effective. CURRENCY RISK At 31 December 2018, the Group’s major foreign currency denominated borrowings are held in individual entities with the same financial reporting currencies as borrowings. Therefore a weakening or strengthening of sterling against the Group’s major currencies would not result in any gains or losses being posted directly to equity and there would be no profit before tax impact. INTEREST RATE RISK A one percentage point increase in market interest rates for all currencies in which the Group had cash and borrowings at 31 December 2018 would increase profit before tax by approximately £7.2 million (2017: £0.2 million). A one percentage decrease in market interest rates would have an equal and opposite effect. This has been calculated by applying the interest rate change to the Group’s variable rate cash and borrowings. 24. FINANCIAL INSTRUMENTS CURRENCY DERIVATIVES The Group utilises currency derivatives to hedge significant future transactions and cash flows and the exchange risk arising on translation of the Group’s investments in foreign operations. The Group is a party to a variety of foreign currency derivatives in the management of its exchange rate exposures. The instruments purchased are primarily denominated in the currencies of the Group’s principal markets. The Group designates its foreign currency-denominated debt as hedging instruments against the currency risk associated with the translation of its foreign operations. Contracts due in March 2025 have receipts of €500.0 million and payments of £444.1 million. At 31 December 2018, the fair value of the Group’s currency derivatives is estimated to be a net asset of approximately £8.4 million (2017: £nil). These amounts are based on market values of equivalent instruments at the balance sheet date, comprising £8.4 million (2017: £nil) assets included in trade and other receivables and £nil (2017: £nil) liabilities included in trade and other payables. The amounts taken to and deferred in equity during the year for currency derivatives that are designated and effective hedges was a charge of £17.9 million (2017: £nil) for cash flow hedges. Changes in the fair value relating to the ineffective portion of the currency derivatives amounted to a loss of £11.1 million (2017: £nil) which is included in the revaluation of financial instruments for the year. This loss resulted from a £6.8 million gain on hedging instruments and a £17.9 million loss on hedged items. At the balance sheet date, the total nominal amount of outstanding forward foreign exchange contracts not designated as hedges was £296.1 million (2017: £177.7 million). The Group estimates the fair value of these contracts to be a net liability of £1.3 million (2017: £2.5 million). These arrangements are designed to address significant exchange exposure and are renewed on a revolving basis as required. INTEREST RATE SWAPS The Group uses interest rate swaps as hedging instruments in fair value hedges to manage its exposure to interest rate movements on its borrowings. Contracts with a nominal value of $500 million have fixed interest receipts of 3.63% until September 2022 and have floating interest payments averaging LIBOR plus 1.52%. Contracts with a nominal value of $812 million have fixed interest receipts of 4.75% until November 2021 and have floating rate payments averaging LIBOR plus 2.34%. The fair value of interest rate swaps entered into at 31 December 2018 is estimated to be a net liability of £14.2 million (2017: £1.2 million). These amounts are based on market values of equivalent instruments at the balance sheet date, comprising £nil (2017: £2.1 million) assets included in trade and other receivables and £14.2 million (2017: £3.3 million) liabilities included in trade and other payables. Changes in the fair value relating to the ineffective portion of interest rate swaps amounted to a gain of £0.9 million (2017: £2.8 million) which is included in the revaluation of financial instruments for the year. This gain resulted from a £9.9 million loss on hedging instruments and a £10.8 million gain on hedged items. WPP ANNUAL REPORT 2018 151

There have been no material changes in the carrying amounts of financial assets and financial liabilities arising from the adoption of IFRS 9. The following table provides an analysis of financial instruments that are measured subsequent to initial recognition at fair value, grouped into levels 1 to 3 based on the degree to which the fair value is observable: Level 1 fair value measurements are those derived from quoted prices (unadjusted) in active markets for identical assets or liabilities; Level 2 fair value measurements are those derived from inputs other than quoted prices included within level 1 that are observable for the asset or liability, either directly (ie as prices) or indirectly (ie derived from prices); Level 3 fair value measurements are those derived from valuation techniques that include inputs for the asset or liability that are not based on observable market data (unobservable inputs). 152 WPP ANNUAL REPORT 2018

FINANCIAL STATEMENTS NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS 27. ACQUISITIONS The Group accounts for acquisitions in accordance with IFRS 3 Business Combinations. IFRS 3 requires the acquiree’s identifiable assets, liabilities and contingent liabilities (other than non-current assets or disposal groups held for sale) to be recognised at fair value at acquisition date. In assessing fair value at acquisition date, management make their best estimate of the likely outcome where the fair value of an asset or liability may be contingent on a future event. In certain instances, the underlying transaction giving rise to an estimate may not be resolved until some years after the acquisition date. IFRS 3 requires the release to profit of any acquisition reserves which subsequently become excess in the same way as any excess costs over those provided at acquisition date are charged to profit. At each period end management assess provisions and other balances established in respect of acquisitions for their continued probability of occurrence and amend the relevant value accordingly through the consolidated income statement or as an adjustment to goodwill as appropriate under IFRS 3. The Group acquired a number of subsidiaries in the year. The following table sets out the book values of the identifiable assets and liabilities acquired and their fair value to the Group. The fair value adjustments for certain acquisitions have been determined provisionally at the balance sheet date. Book Fair Fair value at value value to acquisition adjustments Group £m £m £m Intangible assets – 40.3 40.3 Property, plant and equipment 3.1 – 3.1 Cash 5.0 – 5.0 Trade receivables due within one year 43.7 – 43.7 Other current assets 20.3 – 20.3 Total assets 72.1 40.3 112.4 Current liabilities (42.8) – (42.8) Trade and other payables due after one year (2.4) (13.5) (15.9) Deferred tax liabilities – (9.9) (9.9) Provisions – (0.4) (0.4) Total liabilities (45.2) (23.8) (69.0) Net assets 26.9 16.5 43.4 Non-controlling interests (6.3) Fair value of equity stake in associate undertakings before acquisition of controlling interest (3.1) Goodwill 141.6 Consideration 175.6 Consideration satis?ed by: Cash 127.4 Payments due to vendors 48.2 Goodwill arising from acquisitions represents the value of synergies with our existing portfolio of businesses and skilled staff to deliver services to our clients. Goodwill that is expected to be deductible for tax purposes is £65.3 million. Non-controlling interests in acquired companies are measured at the non-controlling interests’ proportionate share of the acquiree’s identifiable net assets. The contribution to revenue and operating profit of acquisitions completed in the year was not material. There were no material acquisitions completed between 31 December 2018 and the date the financial statements have been authorised for issue. 28. RELATED PARTY TRANSACTIONS From time to time the Group enters into transactions with its associate undertakings. These transactions were not material for any of the years presented. 29. RECONCILIATION TO NON-GAAP MEASURES OF PERFORMANCE Management includes non-GAAP measures as they consider these measures to be both useful and necessary. They are used by management for internal performance analyses; the presentation of these measures facilitates comparability with other companies, although management’s measures may not be calculated in the same way as similarly titled measures reported by other companies; and these measures are useful in connection with discussions with the investment community.

Pass-through costs comprise fees paid to external suppliers when they are engaged to perform part or all of a specific project and are charged directly to clients, predominantly media and data collection costs. This includes the cost of media where the Group’s media investment management sub-sector is buying digital media for its own account on a transparent opt-in basis and, as a result, the subsequent media pass-through costs have to be accounted for as revenue, as well as billings. In addition, the data investment management sector, which forms a significant part of the Group’s revenue and in which none of the Group’s direct competitors have a significant presence, includes pass-through costs, principally for data collection. Therefore, management considers that revenue less pass-through costs gives a reflection of top-line performance. 156 WPP ANNUAL REPORT 2018

The Group bases its internal cash flow objectives on free cash flow. Management believes free cash flow is meaningful to investors because it is the measure of the Group’s funds available for acquisition-related payments, dividends to shareholders, share repurchases and debt repayment. The purpose of presenting free cash flow is to indicate the ongoing cash generation within the control of the Group after taking account of the necessary cash expenditures of maintaining the capital and operating structure of the Group (in the form of payments of interest, corporate taxation and capital expenditure). CONSTANT CURRENCY AND PRO FORMA (‘LIKE-FOR-LIKE’) These consolidated financial statements are presented in pounds sterling. However, the Group’s significant international operations give rise to fluctuations in foreign exchange rates. To neutralise foreign exchange impact and illustrate the underlying change in revenue and profit from one year to the next, the Group has adopted the practice of discussing results in both reportable currency (local currency results translated into pounds sterling at the prevailing foreign exchange rate) and constant currency. Management also believes that discussing pro forma or like-for-like contributes to the understanding of the Group’s performance and trends because it allows for meaningful comparisons of the current year to that of prior years. Further details of the constant currency and pro forma methods are given in the financial glossary on pages 178 and 179. 157

FINANCIAL STATEMENTS INDEPENDENT AUDITOR’S REPORT TO THE MEMBERS OF WPP PLC REPORT ON THE AUDIT OF THE FINANCIAL STATEMENTS OPINION In our opinion: – the financial statements of WPP plc (the ‘Parent Company’) and its subsidiaries (the ‘Group’) give a true and fair view of the state of the Group’s and of the Parent Company’s affairs as at 31 December 2018 and of the Group’s profit and the Parent Company’s loss for the year then ended; – the Group financial statements have been properly prepared in accordance with International Financial Reporting Standards (IFRSs) as adopted by the European Union and IFRSs as issued by the International Accounting Standards Board (IASB); – the Parent Company financial statements have been properly prepared in accordance with United Kingdom Generally Accepted Accounting Practice, including FRS 101 “Reduced Disclosure Framework”; and – the financial statements have been properly prepared in accordance with the Companies (Jersey) Law 1991. We have audited the financial statements which comprise: – the accounting policies; – the consolidated income statement (excluding the US dollar information); – the consolidated statement of comprehensive income; – the consolidated cash flow statement; – the consolidated balance sheet; – the consolidated statement of changes in equity; – the Parent Company profit and loss account, balance sheet and statement of changes in equity; and – the related notes 1 to 37. The financial reporting framework that has been applied in the preparation of the Group financial statements is applicable law and IFRSs as adopted by the European Union. The financial reporting framework that has been applied in the preparation of the Parent Company financial statements is applicable law and United Kingdom Accounting Standards, including FRS 101 “Reduced Disclosure Framework” (United Kingdom Generally Accepted Accounting Practice). BASIS FOR OPINION We conducted our audit in accordance with International Standards on Auditing (UK) (ISAs (UK)) and applicable law. Our responsibilities under those standards are further described in the auditor’s responsibilities for the audit of the financial statements section of our report. We are independent of the Group and the Parent Company in accordance with the ethical requirements that are relevant to our audit of the financial statements in the UK, including the Financial Reporting Council’s (the ‘FRC’s’) Ethical Standard as applied to listed public interest entities, and we have fulfilled our other ethical responsibilities in accordance with these requirements. We confirm that the non-audit services prohibited by the FRC’s Ethical Standard were not provided to the Group or the Parent Company. We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our opinion. SUMMARY OF OUR AUDIT APPROACH Key audit matters The key audit matters that we identified in the current year were: – Revenue recognition: estimate of revenue recognised over time based on the proportion of the level of service performed for open projects at year-end within the Kantar network – Goodwill – Restructuring and transformation costs – Taxation reserves Within this report, any new key audit matters are identified with and any key audit matters which are the same as the prior year identified with . Materiality The materiality that we used for the Group financial statements was £80.0 million (2017: 105.5 million) which we determined using 5.5% (2017: 5%) of pre-tax profit. Scoping Those entities subject to audit provide coverage for 76% of the Group’s consolidated revenue (2017: 78%) and 81% of the Group’s consolidated operating profit (2017: 83%); achieved through a combination of direct testing and specified audit procedures (including substantive analytical review procedures) performed by the Group auditor and/or component auditors across the world. Significant changes in There have been no significant changes in our approach compared with the prior year. However, we revised our assessment of key audit our approach matters as detailed below. WPP ANNUAL REPORT 2018 163

FINANCIAL STATEMENTS INDEPENDENT AUDITOR’S REPORT TO THE MEMBERS OF WPP PLC CONCLUSIONS RELATING TO GOING CONCERN, PRINCIPAL RISKS AND VIABILITY STATEMENT GOING CONCERN We reviewed the Strategic report to shareholders on page 79 to the financial statements as to 1) whether they considered it appropriate to adopt the going concern basis of accounting in the financial statements and 2) their identification of any material uncertainties to the Group’s and Parent Company’s ability to conclude that the going concern basis of accounting is appropriate for a period of at least twelve months from the date of approval of the financial statements. We considered as part of our risk assessment the nature of the Group, its business model and related risks including where relevant the impact of Brexit, the requirements of the applicable financial reporting framework and the system of internal control. We evaluated the directors’ assessment of the Group’s ability to continue as a going concern, including challenging the underlying data and key assumptions used to make the assessment, and evaluated the directors’ plans for future actions in relation to their going concern assessment. We are required to state whether we have anything material to add or draw attention to in relation to that statement required by Listing Rule 9.8.6R(3) and report if the statement is materially inconsistent with our knowledge obtained in the audit. We confirm that we have nothing material to report, add or draw attention to in respect of these matters. PRINCIPAL RISKS AND VIABILITY STATEMENT Based solely on reading the Strategic report to shareholders and considering whether they were consistent with the knowledge we obtained in the course of the audit, including the knowledge obtained in the evaluation of the directors’ assessment of the Group’s and the Parent Company’s ability to continue as a going concern, we are required to state whether we have anything material to add or draw attention to in relation to: – the disclosures on pages 79-83 that describe the principal risks and explain how they are being managed or mitigated; – the directors’ confirmation on page 79 that they have carried out a robust assessment of the principal risks facing the Group, including those that would threaten its business model, future performance, solvency or liquidity; or – the directors’ explanation on page 79 as to how they have assessed the prospects of the Group, over what period they have done so and why they consider that period to be appropriate, and their statement as to whether they have a reasonable expectation that the Group will be able to continue in operation and meet its liabilities as they fall due over the period of their assessment, including any related disclosures drawing attention to any necessary qualifications or assumptions. We are also required to report whether the directors’ statement relating to the prospects of the Group required by Listing Rule 9.8.6R(3) is materially inconsistent with our knowledge obtained in the audit. We confirm that we have nothing material to report, add or draw attention to in respect of these matters. KEY AUDIT MATTERS Key audit matters are those matters that, in our professional judgement, were of most significance in our audit of the financial statements of the current period and include the most significant assessed risks of material misstatement (whether or not due to fraud) that we identified. These matters included those which had the greatest effect on: the overall audit strategy, the allocation of resources in the audit; and directing the efforts of the engagement team. These matters were addressed in the context of our audit of the financial statements as a whole, and in forming our opinion thereon, and we do not provide a separate opinion on these matters. Given the reduced financial significance of media volume income for the Group, we no longer identified this as a key audit matter in the current year. However, upon the announcement of the potential sale of the Kantar network, which is part of Data Investment Management, we identified that there is a potential for fraud in relation to the cut-off of revenue recognised on open projects at year-end accounted for as revenue recognised over time based on the proportion of the level of service performed within the Kantar network. Therefore, this has been included as a key audit matter in the current year. In addition, with the increase in costs incurred in respect of restructuring, we have included this as a key audit matter in the current year. 164 WPP ANNUAL REPORT 2018
