? Gradual recovery in Europe, up 1.2% in local currencies

? Dynamic growth in construction chemicals, up 18.0% in local currencies driven by double-digit sales growth from recent acquisitions and an outperformance in like-for-like sales (up 2.6%)

? Roll-out of ¡°Lead & Grow¡± plan to accelerate profitable growth for 2026-2030, as presented at the Capital Markets Day on October 6, 2025

? 2025 outlook confirmed: the Group expects an operating margin of more than 11.0%

Sales for the third quarter increased 1.3% in local currencies, benefitting from stabilized like-for-like sales (down 0.2%), supported by good momentum in Asia-Pacific and Latin America and Europe¡¯s return to growth, despite the contraction in North America.

Construction chemicals sales rose 2.6% like-for-like, thanks to growth across all geographic areas.

In a less inflationary cost environment, prices were 0.7% higher in the third quarter thanks to disciplined execution and to the added value of our comprehensive, innovative and sustainable solutions. Volumes were down 0.9%, representing a sequential improvement on the second quarter (down 1.8%).

The positive 1.5% structure impact primarily reflects the acquisitions of Cemix in Latin America and FOSROC in India and the Middle East, in line with the Group¡¯s strategy targeting high-growth countries and construction chemicals. The integration of recent acquisitions is progressing well, delivering the expected synergies. The optimization of the Group¡¯s profile also continued with the effect of divestments, notably the pipe drainage business for buildings (PAM Building) as well as Br¨¹ggemann in Germany.

On a reported basis, sales came to €11.42 billion in third-quarter 2025 (down 1.3%), owing to the depreciation of most currencies against the euro, with a negative 2.6% currency impact, particularly in the Americas Region.

Performance by Region (sales)

Asia-Pacific: sales growth driven by India

The Region delivered growth of 8.4% in local currencies and of 3.4% like-for-like in the third quarter (after growing 1.1% in the second quarter), driven by India and South-East Asia.

India achieved further market share gains, with double-digit volume growth, driven by its comprehensive and innovative range of sustainable solutions. The Group was awarded new projects in non-residential and infrastructure, testifying to its leadership in construction chemicals, reinforced by its acquisition of FOSROC. China improved, including industrial solutions, in a market that is stabilizing at a low level. Good momentum in South-East Asia continued, driven by Indonesia and Vietnam on the back of a major contract at Long Thanh airport, comprising 15 solutions specified by the Group.

2025 outlook

In a macroeconomic environment that remains contrasted, Saint-Gobain will once again demonstrate a very strong operating performance in second-half 2025. Assuming no major slowdown in global growth linked to geopolitical uncertainties, the Group expects the following trends:

? Europe: a gradual recovery country by country;

? Americas: a good level of activity to be maintained in Latin America and continued softness in new construction in North America amid still-high interest rates;

? Asia-Pacific: growth led mainly by India, South-East Asia and the integration of CSR in Australia.

Saint-Gobain expects an operating margin of more than 11.0% in 2025
