• Sustained sales momentum:
  • First nine months 2026 revenue of €2.62 billion: +2.0% at constant exchange rates and perimeter, supported by higher sales volumes (+0.4% vs last year) and steady pricing

• Adjusted EBITDA growth:
  • First nine months 2026 adjusted EBITDA of €450 million: +10.3% year-on-year at constant exchange rates and perimeter; YTD adjusted EBITDA margin at 17.1%, representing a 0.8 pp improvement versus last year and highlighting the Group’s operating leverage
  • Q3 2026 adjusted EBITDA of €160 million: +10.8% versus last year at constant exchange rates and perimeter; Q3 adjusted EBITDA margin at 18.1%, a 1.2 pp increase year-over-year
• Full-year 2026 adjusted EBITDA target raised to €570-€590 million, assuming no material deterioration in the current operating environment, up from €550-€580 million¹

Alessandro Dazza, Chief Executive Officer, said:

« Our strong first nine months performance demonstrates Imerys’ ability to deliver sales growth and sustained margin expansion even in challenging market conditions. Our targeted investments and continued innovation are delivering tangible results, as is Project Horizon, our cost and performance improvement program, which is progressing ahead of schedule. Our recent bolt-on acquisitions Great Lakes Minerals and S&B Mineração are already proving earnings-accretive. These achievements underpin our decision to raise our full-year 2026 adjusted EBITDA guidance to a range of €570 to €590 million, reinforcing our confidence in Imerys’ profitable growth trajectory. »

OUTLOOK

Our solid performance in the first nine months of 2026, supported by sales growth, margin expansion and continued progress on our strategic initiatives, reinforces our confidence in delivering full-year 2026 results significantly above last year.

Accordingly, Imerys is raising its full-year 2026 adjusted EBITDA guidance to a range of €570 to €590 million, assuming no material deterioration in the current operating environment.

The Group remains focused on protecting margins through disciplined pricing and ongoing cost optimization as inflationary pressures and challenging market conditions are likely to prevail in the near future. Strong cash generation, rigorous financial discipline and the continued execution of our strategic growth initiatives will remain key priorities.

Revenue

Third-quarter 2026 revenue reached €884 million, up 7% versus last year. At constant exchange rates and perimeter, revenue was up 2.9%. Sales volumes edged up 0.2% as robust sales of conductive additives, strong momentum in Asia, and market share gains successfully offset sluggish demand in Europe. Selling prices increased by 2.7%, mainly driven by the pass-through of higher energy and logistics costs. In addition, the consolidation of the recent bolt-on acquisitions, Great Lakes Minerals from June 1, 2026, and S&B Mineração from July 1, 2026, contributed €23 million to third-quarter revenue. FX impacts turned positive in Q3 (+€11million), primarily driven by a stronger US dollar against the euro.

First nine months 2026 revenue was €2,624 million, representing a 2.0% increase on a like-for-like basis. Sales volumes rose by 0.4% thanks to the strong performance of our sales teams and the ramp up of new industrial capacities, fully offsetting soft overall demand, particularly in construction. Pricing was firm (+1.6% year on year). The integration of Great Lakes Minerals and S&B Mineração added 1.1% to total revenue, whereas exchange rates had a negative impact of 1.4% year-to-date, mainly attributable to Q1 2026.

Adjusted EBITDA

Q3 2026 adjusted EBITDA reached €160 million, a solid 10.8% increase year-on-year on a like-for-like basis, supported by tight cost control and firm pricing. Great Lakes Minerals and S&B Mineração are already contributing to the Group Adjusted EBITDA with margins in line with the rest of the Group.

As a result, adjusted EBITDA for the first nine months 2026 reached €450 million, up 10.3% organically year-over-year, fueled by higher sales volumes, firm pricing and disciplined cost management.

Imerys achieved an adjusted EBITDA margin of 17.1% in the first nine months of 2026, up 0.8 pp versus last year resulting from the strong performance achieved in the second and third quarters 2026 (respectively 19.0% and 18.1% margin on sales).

Current net income

Current net income, Group share in the first nine months of 2026, totaled €116 million. The current financial result was negative at €66 million. This includes a €6 million non-cash mark-to-market revaluation of Purchase Power Agreements (PPAs) and a €9 million increase in interest expenses. The income tax expense of €43 million corresponds to an effective tax rate of 27%.​

Net income

Net income, Group share in the first nine months of 2026 totaled €92 million vs €110 million in the prior year. It includes restructuring expenses for Project Horizon, partly offset by a revaluation gain on the EMILI lithium project following the €50 million equity stake purchase by the Banque des Territoires in April 2026.

PERFORMANCE BY ACTIVITY

Performance Minerals

*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. Totals remain unchanged.

Performance Minerals generated revenue of €1,556 million in the first nine months of 2026, benefitting from positive organic growth year-on-year, largely driven by a strong activity in the Americas from Q2 2026 onwards.

Revenue in the Americas grew 4.3% at constant exchange rates and perimeter to reach €636 million in the first nine months of 2026. Sales volumes were positive (+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) that was primarily fueled by market share gains. Pricing remained firm over the period.

Revenue in Europe, Middle East, Africa and Asia-Pacific was broadly in line with the prior year at €984 million in the first nine months of 2026 (+0.3% year-on-year at constant exchange rates and perimeter). Volumes dropped slightly year-on-year as sales to ceramics were severely impacted by high energy costs and soft construction demand, partially offset by market share gains in polymers and filtration. Prices rose 2.7% in the period, partly driven by pricing adjustments in response to higher energy costs.

Third quarter revenue came in 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.

Solutions for Refractory, Abrasives and Construction

Revenue generated by Solutions for Refractory, Abrasives and Construction reached €865 million in the first nine months of 2026 in line with last year at constant exchange rates and perimeter. Sales volumes were flat over the period. Negative sales volumes in the European refractory market, impacted by weak demand, were offset by strong performance in the abrasives and advanced ceramics segments, particularly in China and, to a lesser extent, the US.

The decline in Q3 revenue can be attributed to the refractory business as tighter EU import quotas on Chinese steel implemented on July 1 proved insufficient to offset subdued end-market demand in Europe. However, sales to the construction sector rebounded from their H1 2026 level, driven by market share gains while the abrasives and advanced ceramics segments continued their positive momentum. Finally, the integration of Great Lakes Minerals is progressing well.

Solutions for Energy Transition

In the first nine months of 2026, the Graphite and Carbon business generated €207 million in revenue, delivering a 16.0% increase at constant scope and exchange rates versus last year. Organic growth accelerated to 21% in Q3, exceeding the pace recorded in the first half. Top-line performance was supported by favorable market conditions, particularly in electric vehicles and energy storage systems, and to a lesser extent in conductive polymers. Market share gains and new product launches also contributed.

The Quartz Corporation business (high-purity quartz joint venture, 50% owned by Imerys) is stabilizing, with growth in the semiconductor market offsetting softer demand in the photovoltaic sector.
