Cautionary statement

The Group’s reports filed with or furnished to the US Securities and Exchange Commission (SEC), including the 2016 Annual Report and written information released, or oral statements made, to the public in the future by or on behalf of the Group, may contain forward-looking statements. Forward-looking statements give the Group’s current expectations or forecasts of future events. An investor can identify these statements by the fact that they do not relate strictly to historical or current facts. They use words such as ‘anticipate’, ‘estimate’, ‘expect’, ‘intend’, ‘will’, ‘project’, ‘plan’, ‘believe’ and other words and terms of similar meaning in connection with any discussion of future operating or financial performance. In particular, these include statements relating to future actions, prospective products or product approvals, future performance or results of current and anticipated products, sales efforts, expenses, the outcome of contingencies such as legal proceedings, and financial results. Other than in accordance with its legal or regulatory obligations (including under the UK Listing Rules and the Disclosure and Transparency Rules of the Financial Conduct Authority), the Group undertakes no obligation to update any forward-looking statements, whether as a result of new information, future events or otherwise.

The reader should, however, consult any additional disclosures that the Group may make in any documents which it publishes and/or files with the SEC. All readers, wherever located, should take note of these disclosures. Accordingly, no assurance can be given that any particular expectation will be met and shareholders and investors are cautioned not to place undue reliance on the forward-looking statements.

Forward-looking statements are subject to assumptions, inherent risks and uncertainties, many of which relate to factors that are beyond the Group’s control or precise estimate. The Group cautions investors that a number of important factors, including those in this microsite, could cause actual results to differ materially from those expressed or implied in any forward-looking statement. Such factors include, but are not limited to, those discussed under ‘Risk factors’ on pages 253-262 of the 2016 Annual Report. Any forward-looking statements made by or on behalf of the Group speak only as of the date they are made and are based upon the knowledge of and information available to the Directors on the date of the 2016 Annual Report.

The information in this microsite does not constitute an off to sell or an invitation to buy shares in GlaxoSmithKline plc or an invitation or inducement to engage in any other investment activities. Past performance cannot be relied upon as a guide to future performance.

Nothing in the 2016 Annual Report should be constructed as a profit forecast. All expectations and targets regarding future performance should also be read together with ‘Assumptions related to 2016-2020 outlook’ which can be found on the final page of the 2016 Annual Report.

A number of adjusted measures are used to report the performance of our business. These measures are defined on page 57 of the 2016 Annual Report and a reconciliation of core results to total results is set out on page 66 of the 2016 Annual Report.
