Non-IFRS Measures This presentation contains certain financial measures that are not presented in accordance with the International Financial Reporting Standards (“IFRS”), including, but not limited to, Adjusted Gross Margin, Adjusted Operating Profit, Adjusted Operating Profit Margin, Return on Capital Employed (“ROCE”), Adjusted Diluted Earnings per Share, Total Constant Exchange Rate Revenue (“CER revenue”), and Free Cash Flow. These non-IFRS financial measures are not measures of financial performance in accordance with IFRS and may exclude items that are significant in understanding and assessing Abcam’s financial results. Therefore, these measures should not be considered in isolation or as an alternative to profit for the year, cash flows from operations or other measures of profitability, liquidity or performance under IFRS. Abcam’s presentation of these measures may not be comparable to similarly titled measures used by other companies. Third party data Unless otherwise indicated, information contained in this presentation concerning our industry, competitive position and the markets in which we operate is based on information from independent industry and research organizations, other third-party sources and management estimates. Management estimates are derived from publicly available information released by independent industry analysts and other third-party sources, as well as data from our internal research, and are based on assumptions made by us upon reviewing such data, and our experience in, and knowledge of, such industry and markets, which we believe to be reasonable. In addition, projections, assumptions and estimates of the future performance of the industry in which we operate and our future performance are necessarily subject to uncertainty and risk due to a variety of factors, including those described above. These and other factors could cause results to differ materially from those expressed in the estimates made by independent parties and by us. Some information contained herein has been obtained from other third-party sources and has not been independently verified by Abcam. While Abcam believes that its internal assumptions are reasonable, the sources relied on may be based on a small sample size and may fail to accurately reflect market opportunities. Moreover, no independent source has verified such assumptions, and Abcam did not commission any of the market and industry data presented herein. Industry publications, research, surveys, studies and forecasts generally state that the information they contain has been obtained from sources believed to be reliable but that the accuracy and completeness of such information is not guaranteed. The trademarks included herein are the property of the owners thereof and are used for reference purposes only. Such use should not be construed as an endorsement of the products or services of Abcam or the proposed offering.
