Investor Presentaiton

Non-GAAP Financial Measures It should be noted that adjusted net (loss) income attributable to Albemarle Corporation, adjusted diluted earnings per share ("EPS"), non-operating pension and other post-employment benefit ("OPEB") items per diluted share, non-recurring and other unusual items per diluted share, adjusted effective income tax rates, EBITDA, adjusted EBITDA (on a consolidated basis), EBITDA margin and adjusted EBITDA margin are financial measures that are not required by, or presented in accordance with, accounting principles generally accepted in the United States, or GAAP. These non-GAAP measures should not be considered as alternatives to net income attributable to Albemarle Corporation ("earnings") or other comparable measures calculated and reported in accordance with GAAP. These measures are presented here to provide additional useful measurements to review the company's operations, provide transparency to investors and enable period-to-period comparability of financial performance. The company's chief operating decision maker uses these measures to assess the ongoing performance of the company and its segments, as well as for business and enterprise planning purposes. A description of other non-GAAP financial measures that Albemarle uses to evaluate its operations and financial performance, and reconciliation of these non-GAAP financial measures to the most directly comparable financial measures calculated and reported in accordance with GAAP can be found on the press release announcing the results discussed in this presentation, which is available on Albemarle's website at https://investors.albemarle.com. The company does not provide a reconciliation of forward-looking non-GAAP financial measures to the most directly comparable financial measures calculated and reported in accordance with GAAP, as the company is unable to estimate significant non-recurring or unusual items without unreasonable effort. The amounts and timing of these items are uncertain and could be material to the company's results calculated in accordance with GAAP. AAlbemarle 3
