DATA METHODOLOGY Data Coverage We expanded our coverage of data verification from 94 sites in 2019 to 112 operational sites in 2021. We report data for our operations on a 100%ownershipbasis unless stated otherwise (e.g. for an 80% owned operation, we report 100% of the data). The information presented in this report refers to the Company, while the metric system and US$ (dollars) are used to report data. The inherent limitations present in the measuring and repor t ing of non- f inancial informat ion subject this information to an undetermined number of uncertainties. Measurement techniques and data selection criteria can vary between IVL and our subsidiaries. However, we remain steadfast in reporting the most comprehensive and accurate metrics possible within our capacity. Changes in size, structure, ownership, and developments The list of entities acquired, incorporated and other developments is available in the 2021 Annual Report on pg. 66 and on our website under “investor-relations newsroom.” Exceptions We curated the content for the 2021 Sustainability Report using environmental, safety, governance and human resources data derived from all entities including joint ventures in which we hold a minimum share of 50% and have management control.

They reflect the Company’s views at the time such statementsweremade with respect to future events and offer investors and other stakeholders important insights into our vision in attaining long-term success. These forward-looking statements relay anticipated future outcomes through the usage of words such as ‘aim,’ ‘believe,’ ‘estimate,’ ‘expect,’ ‘goal,’ ‘intend,’ ‘may,’ ‘plan,’ ‘target,’ ‘will’ and other similar expressions. These forward-looking statements are, by their nature, subject to r isks and uncer taint ies due to thei r presumptive nature, which may affect our ability to deliver on our targets. For example, shifts in legal and regulatory frameworks, national fiscal complexities which can affect our ability to compete effectively, trends and conditions in the industry, andgeographical markets in which IVL operates. IVL undertakes no obligation to update any forward-looking statements, whether as a result of new information, future events or otherwise. Therefore, readers are asked to accept a degree of ambiguity inherent within forward-looking statements when assessing the information provided therein. Investors are cautioned not to place undue reliance on any such forward-looking statements, which speak only as of the date they are made. All forward-looking statements herein are qualified by reference to the cautionary statements set forth in this section. FEEDBACK We welcome your comments, thoughts and remarks.
