Change in presentation currency – additional conversion information

In February 2018, Ardagh Group S.A. (the “Group”) announced that with effect from January 1, 2018 the Group will change the currency in which it presents its financial statements from euro to U.S. dollar. This is principally as a result of the Group’s assessment that this change will help provide a clearer understanding of the Group’s financial performance and improve comparability of our performance following the Group’s IPO on the New York Stock Exchange.

Consequently, selected unaudited financial information for the financial years ended December 31, 2017 and 2016 is provided in U.S. dollar for informational purposes in the attached appendix. The consolidated financial statements of Ardagh Group S.A. for the financial years ended December 31, 2017, 2016 and 2015, re-presented in U.S. dollar will be provided in due course.

1 Adjusted EBITDA consists of profit/(loss) for the year before income tax expense/(credit), net finance expense, depreciation and amortization and exceptional operating items. Adjusted EBITDA is presented because we believe that it is frequently used by securities analysts, investors and other interested parties in evaluating companies in the packaging industry. However, other companies may calculate Adjusted EBITDA in a manner different from ours. Adjusted EBITDA is not a measurement of financial performance under IFRS and should not be considered an alternative to profit/(loss) as an indicator of operating performance or any other measure of performance derived in accordance with IFRS.
