October 29, 2026| Imerys 2026 First Nine Months and Third Quarter Results Q3 and First nine months 2026 - Performance Minerals ● Performance Minerals Americas: ○ Revenue in the Americas: +4.3% at constant exchange rates and perimeter to reach €636 million in the first nine months of 2026. Positive sales volumes (+1.6% year-on-year). Robust performance in filtration and polymers, driven by market share gains, more than offset declining sales to the construction sector ○ Third-quarter revenue reached €219 million, led by solid volume growth (+4.6% vs Q3 2025) primarily fueled by market share gains. Pricing firm over the period ● Performance Minerals Europe, Middle East, Africa and Asia-Pacific: ○ Revenue in Europe, Middle East, Africa and Asia-Pacific broadly in line with the prior year at €984 million in the first nine months of 2026 Slight volumes drop year-on-year as sales to ceramics were severely impacted by high energy costs and soft construction demand, only partially offset by market share gains in polymers and filtration. Prices up 2.7% in the period, driven by necessary adjustments in response to higher energy costs ○ Third quarter revenue at €325 million, slightly above the previous year. Sales volumes declined by 2.7% compared with the third quarter 2025, mainly driven by a drop in ceramics sales Q3 2025* Q3 2026 Like-for-like change Consolidated results (in € million) 9 months* 2025 9 months 2026 Like-for-like change 191 219 +8.0% Revenue Americas 617 636 +4.3% 319 325 +1.2% Revenue Europe, Middle East and Africa and Asia-Pacific 990 984 +0.3% -19 -22 - Eliminations -60 -64 - 491 522 +3.3% Total revenue 1,547 1,556 +1.5% *Q3 and 9 months 2025 figures have been adjusted compared to actual results announced on October 30, 2025, to reflect the internal transfer of the Asian filtration business from the Americas to Europe, Middle East and Africa and Asia-Pacific region for operational management purposes.

October 29, 2026| Imerys 2026 First Nine Months and Third Quarter Results Solutions for Refractory, Abrasives & Construction: ● Revenue in the first nine months of 2026 in line with last year at constant exchange rates and perimeter. Sales volumes flat over the period. Negative sales volumes in the European refractory market, impacted by weak demand, offsetted by strong performance in the abrasives and advanced ceramics segments, particularly in China and, to a lesser extent, in the US ● Decline in Q3 revenue attributed to the refractory business as tighter EU import quotas on Chinese steel implemented from July 1 proved insufficient to offset subdued end-market demand in Europe. Rebound of sales to the construction sector, driven by market share gains, and continued positive momentum in the abrasives and advanced ceramics segments.

October 29, 2026| Imerys 2026 First Nine Months and Third Quarter Results Glossary Alternative Performance Measures Definitions and reconciliation to IFRS indicators Growth at constant scope and exchange rates (also called like-for-like growth, LFL, organic growth or internal growth) Calculated by stripping out the impact of currency fluctuations as well as acquisitions and disposals (scope effect). Restatement of the currency effect consists of calculating aggregates for the prior year at the exchange rate of the current year. The impact of exchange rate instruments qualifying as hedging instruments is taken into account in current data. Restatement of Group structure to take into account newly consolidated entities consists of subtracting the contribution of the acquisition from the aggregates of the current year, for entities entering the consolidation scope in the current year and subtracting the contribution of the acquisition from January 1 of the current year, until the last day of the month of the current year when the acquisition was made the prior year, for entities entering the consolidation scope in the prior year. Restatement of entities leaving the consolidation scope consists of subtracting the departing entity’s contribution from the aggregates of the prior year as from the first day of the month of divestment, for entities leaving the consolidation scope in the current year and subtracting the departing entity’s contribution from the aggregates of the prior year, for entities leaving the consolidation scope in the prior year. Volume effect The sum of the change in sales volumes of each business area between the current and prior year, valued at the average sales price of the prior year. Price mix effect The sum of the change in average prices by product family of each business area between the current and prior year, applied to volumes of the current year. Current operating income The operating income before other operating income and expenses (income from changes in control and other non-recurring items). Net income from current operations The Group’s share of income before other operating income and expenses, net (income from changes in control and other non-recurring items, net of tax) and income from discontinued operations. Adjusted EBITDA Effective January 1, 2024, adjusted EBITDA is calculated from current operating income before operating amortization, depreciation, impairment losses and adjusted for changes in operating provisions and write-downs. It includes the share in net income of joint ventures (instead of dividends received, in the prior definition) to better reflect their contribution to the Imerys Group. Net current free operating cash flow Calculated from current operating income before operating amortization, depreciation and impairment losses and adjusted for changes in operating provisions and write-downs, share in net income and including dividends received from joint ventures and associates, adjusted for notional income tax on current operating income, changes in operational working capital requirement, proceeds from divested intangible and tangible assets, paid intangible and tangible capital expenditure and repayments of lease liabilities. Net financial debt The difference between borrowings and financial debt and cash and cash equivalents. Notional income tax rate Income tax rate on current operating income.
