Imerys delivers robust first quarter 2024 results with 9% year-one-year increase in adjusted EBITDA

Initial signs of demand recovery with first quarter revenue at €926 million, exceeding both Q3 and Q4 2023 levels
Adjusted EBITDA at €188 million (+9% vs last year), reflecting positive contribution of commercial actions, savings measures and lower input costs, as well as strong performance of joint ventures
Positive price/cost balance maintained, demonstrating the strength of Imerys' business model
Progress in strategic roadmap⁶ :
- Creation of a new business area "Solutions for Energy Transition", to reflect accelerating momentum in critical minerals and their growing contribution to the Group's financial performance
- Exclusive negotiations to acquire Chemviron's European diatomite and perlite business, enhancing Imerys offering of natural solutions for consumer goods
- Exclusive negotiations for the divestiture of the Group's assets serving the paper market, with closing expected in the course of the year

Alessandro Dazza, Chief Executive Officer, said:

"As expected, low levels of activity in residential construction and industrial markets continue to penalize the recovery in end-markets, especially in Europe, while the US is showing better resilience and China is improving. We believe we have turned a corner and anticipate a positive impact from lower interest rates in the second half of the year. Amid this mixed environment, Imerys is fully leveraging its resilient business model, broad geographic exposure and end-market diversification. Furthermore, the Group once again demonstrates its ability to adapt its cost structure to fluctuating demand, maintaining a positive price-mix cost balance and generating substantial savings from the cost reduction program launched in 2023. We continue to execute on our strategic roadmap, and look forward to updating the markets in due course."

UPDATE ON STRATEGIC PROJECTS

Imerys has formed a new business area, "Solutions for Energy Transition" (SET), to better reflect the importance and fast-growing contribution of the Group's activities in critical minerals. It includes Imerys Graphite & Carbon business and the Group's share (50% ownership) in the joint-venture The Quartz Corporation. These activities represent key drivers of Imerys' future growth.

As part of the Group's active portfolio management, two important transactions are under exclusive negotiations:

On April 29, 2024, with Chemviron, a subsidiary of Calgon Carbon Corporation, in order to acquire its diatomite and perlite business. Through this acquisition, Imerys would extend and complement its European footprint in diatomite and perlite, and broaden its Filtration and Life Sciences product portfolio, to better serve its customers in the food, beverage, filtration and pharmaceutical markets. It would also allow Imerys to expand its offering of natural solutions for consumer goods. Imerys would acquire three high-quality mining and industrial assets in France and in Italy. In 2023, this business generated approximately €50 million in revenue with 130 employees.
On March 28, 2024, with Flacks Group, for the divestment of the Group's assets serving the paper market. The transaction is expected to be completed in the course of 2024. At closing, the translation reserve associated with the business disposed of (mainly relating to the devaluation of the Brazilian Real) shall be recycled to the profit and loss statement in accordance with applicable IFRS standards. The Group's shareholders equity will not be affected by this non-cash loss currently estimated at circa €300 million as of March 31, 2024.

OUTLOOK

We anticipate a progressive market recovery and sequential sales volumes improvement in the quarters to come as the European economy is stabilizing while the US and Asia remain resilient. In the coming months, Imerys expects to benefit from this positive trend and from innovative products, while remaining costeffective in this still uncertain environment.

Solutions for the Energy Transition, comprising Graphite & Carbon, mainly serving the mobile energy market, and Imerys' participation in The Quartz Corporation (TQC), a 50%-owned joint-venture, serving the solar and semiconductor markets with high-purity quartz solutions.

Revenue in the Americas was down 1.2% at constant scope and exchange rates in the first quarter 2024, reaching €259 million. Sales were impacted by a slowdown in demand for minerals in the construction industry in the US and in filtration markets. Compared to Q3 2023 and Q4 2023, Performance Minerals Americas improved by 1% and 5% respectively.

Revenue in Europe, Middle East, Africa and Asia-Pacific decreased by 7.5% at constant scope and exchange rates in the first quarter 2024.

GLOSSARY

Imerys uses "current" indicators to measure the recurrent performance of its operations, excluding significant items that, because of their nature and their relatively infrequent occurrence, cannot be considered as inherent to the recurring performance of the Group (see section 5.5 Definitions and reconciliation of alternative performance measures to IFRS indicators in the 2021 Universal Registration Document).

Alternative Measures	Performance	Definitions and reconciliation to IFRS indicators
Growth at constant scope and exchange rates (also called life for-like change, LFL growth organic 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 current year at the exchange rate of the prior 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; 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; 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.
Current EBITDA		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 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 changes in right-of-use assets.
Net financial debt		Difference between financial liabilities (borrowings, financial debts, and IFRS 16 liabilities) and cash and cash equivalents.
Notional income tax rate		Income tax rate on current operating income
