TR-1 regulatory

"TR-1: Standard form for notification of major holdings"

A TR-1 is a financial form used by investors to report significant ownership stakes in a company, typically when they acquire or dispose of a large number of shares. It helps keep the market informed about major shareholders and potential changes in control, allowing other investors to make better-informed decisions. This transparency encourages fair trading and reduces surprises related to ownership shifts.

voting rights attached to shares financial

"% of voting rights attached to shares (total of 8.A)"

financial instruments financial

"% of voting rights through financial instruments (total of 8.B 1 + 8.B 2)"

Financial instruments are assets or contracts that hold monetary value and can be bought, sold, or traded. They serve as tools for investors to grow, protect, or transfer money, much like how a ticket or voucher can be used to access goods or services. These instruments help individuals and organizations manage financial goals and risks across different markets and economic conditions.

American Depository Receipt financial

"Type of financial instrument | ... | American Depository Receipt"

An American Depositary Receipt (ADR) is a certificate issued by a U.S. bank that represents ownership of shares in a foreign company and lets those shares trade on U.S. exchanges in U.S. dollars. For investors, ADRs remove many barriers to buying foreign stocks—handling currency conversion, settlement and some reporting—so holding an ADR is like using a local adapter that makes a foreign security behave more like a domestic one, improving access and liquidity.

Securities Lending financial

"Type of financial instrument | ... | Securities Lending"

Securities lending is when an owner of stocks or bonds temporarily loans them to another party, usually so the borrower can sell them short or meet settlement needs; the lender receives a fee and typically some form of security in return. Investors should care because lending can generate extra income on holdings and affects market liquidity and short-selling activity, much like renting out a spare room brings income while someone else uses the space.

CFD financial

"Type of financial instrument | ... | CFD"

A CFD (contract for difference) is a financial agreement that lets an investor profit from the change in an asset’s price without actually owning that asset — like betting on a car’s value rising or falling without buying the car. It matters because CFDs use leverage, which can amplify gains and losses and allow easy access to different markets, so they change an investor’s potential return and risk profile and can lead to rapid losses if prices move unfavorably.

Forward-Looking Statements

The Company may include forward-looking statements (including as defined in the U.S. Private Securities Litigation Reform Act of 1995) in oral or written public statements issued by or on behalf of the Company. These forward-looking statements may include, among other things, plans, objectives, beliefs, intentions, strategies, projections and anticipated future economic performance based on assumptions and the like that are subject to risks and uncertainties. These statements can be identified by the fact that they do not relate strictly to historical or current facts. They use words such as ‘aim’, ‘anticipate’, ‘believe’, ‘estimate’, ‘expect’, ‘forecast’, ‘guidance’, ‘intend’, ‘may’, ‘will’, ‘should’, ‘potential’, ‘possible’, ‘predict’, ‘project’, ‘plan’, ‘target’, and other words and similar references to future periods but are not the exclusive means of identifying such statements. 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 unanticipated loss of a material client or key personnel; delays, suspensions 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 conflicts in Ukraine and the Middle East; the risk of global economic downturn; slower growth, increasing interest rates and high and sustained inflation; tariffs and other trade barriers; 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; effectively managing the risks, challenges and efficiencies presented by using Artificial Intelligence (AI) and Generative AI technologies and partnerships in our business; risks related to our environmental, social and governance goals and initiatives, including impacts from regulators and other stakeholders, and the impact of factors outside of our control on such goals and initiatives; 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 Company’s most recent Annual Report on Form 20-F, which could also cause actual results to differ from forward-looking information. In light of these and other uncertainties, the forward-looking statements included in this document should not be regarded as a representation by the Company that the Company’s plans and objectives will be achieved. 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. Other than in accordance with its legal or regulatory obligations (including under the Market Abuse Regulation, the UK Listing Rules and the Disclosure and Transparency Rules of the Financial Conduct Authority), the Company undertakes no obligation to update or revise any such forward-looking statements, whether as a result of new information, future events or otherwise.
