Second quarter and first half 2021 figures contained in this presentation have not been audited or reviewed by external auditors.

This presentation includes Alternative Performance Measures (APM), including EBITDA, EBITDA margin, EBIT, EBIT margin, net debt and capital expenditures which are not measures of liquidity or financial performance under International Financial Reporting Standards (IFRS). EBITDA is defined as operating profit for the period (i.e. EBIT) before the impact of amortisation, depreciation, impairment and provisions. EBITDA margin is defined as EBITDA divided by revenue. EBIT is defined as Operating profit for the year. The Company uses EBIT to monitor its financial return after both operating expenses and a charge representing the cost of usage of both its property, plant and equipment and definite-life intangible assets. EBIT margin is defined as EBIT as a percentage of revenue. These non-IFRS measures should not be considered in isolation or as an alternative to results from operating activities, cash flow from operating, investing or financing activities, or other financial measures of Befesa's results of operations or liquidity derived in accordance with IFRS. Befesa believes that the APM included in this report are useful measures of its performance and liquidity. Other companies, including those in the industry in which Befesa operates, may calculate similarly titled financial measures differently than Befesa does. Because all companies do not calculate these financial measures in the same manner, Befesa's presentation of such financial measures may not be comparable to other similarly titled measures of other companies. These APM are not audited.

• Address shortage of zinc refining capacity in the US/North America
• Supports AZR to become vertically-integrated:
  • Closed-loop, end-to-end, 100% green to AZR's EAF steel clients
  • Reduces exposure to zinc treatment charge volatility
• No change in Befesa's global strategy
