Benoit Bazin, Chairman and Chief Executive Officer of Saint-Gobain, commented:

“In 2025 Saint-Gobain once again demonstrated the strength of its strategic position as worldwide leader in light and sustainable construction and another strong operating performance thanks to its decentralized country-based organization, which is particularly well suited to the current global environment. I’m extremely grateful for the dedication and contribution of all our teams, enabling the Group to outperform in both developed markets and emerging countries. Despite a turbulent global environment, in particular with a difficult North American market, we delivered stable margins for the year, including in the second half. The Group successfully completed its 2021-2025 “Grow & Impact” plan, meeting all of its financial and strategic objectives.

2026 opens an attractive new chapter of profitable growth and outperformance driven by “Lead & Grow”, our new strategic plan for 2026-2030, which will deepen our solutions offering and accelerate our growth in infrastructure and non-residential. We will continue to enhance our profile, with asset rotation representing over 20% of sales, investing in high-growth regions and further strengthening our positions in construction chemicals.

In the short term, in an environment that remains mixed and uncertain, all our teams are mobilized to seize local market opportunities and drive commercial outperformance, while implementing productivity measures and cost savings where necessary. I am confident in the value creation that “Lead & Grow” will bring to both our customers and our shareholders.”

Successful completion of the “Grow & Impact” strategic plan

All financial targets achieved with, on average over 2021-2025:

• Organic sales growth¹ at 3.0%; operating margin at 10.9% and EBITDA margin at 14.7%;
• Free cash flow conversion ratio at 59%;
• ROCE at 15.1% and approximately €1.4 billion returned to shareholders per year in dividends and net share buybacks (€7 billion in total over the period).

A dynamic and attractive strategy:

• Value-creating optimization of the Group’s scope, with around 40% of Group sales rotated since 2018: around €10 billion in sales divested and €7 billion acquired. This has led to a strong rise in profitability and a balanced earnings contribution from three geographic areas, with in 2025: Asia and emerging countries (36%), Western Europe (33%) and North America (31%);
• Creation of a worldwide leadership position in construction chemicals, with 39 acquisitions in five years (notably Chryso, GCP, Cemix and FOSROC); acceleration in like‑for-like sales in the second half (up 2.8%);
• A highly-effective, proven operating model by country, enabling Saint-Gobain to outperform in both developed markets (US, France, UK, Spain, Italy) and emerging countries (India, South-East Asia, Brazil, Mexico). Perfectly adapted to the current geopolitical environment, this model enables us to accelerate growth in solutions, while sourcing and integrating value-creative acquisitions: combined EBITDA margin of 20% for Chryso and GCP (up 600 basis points in three years), 18% for Canadian acquisitions (Bailey, Building Products of Canada and Kaycan), over 17% for CSR in Australia and 20% for FOSROC and Cemix with double-digit sales growth for the first year.

An established worldwide leadership in light and sustainable construction, with a differentiated offer of sustainable solutions – a competitive advantage – thanks to its ESG roadmap:

• A pioneering and comprehensive range of around 400 low-carbon solutions: Carbon Low (plasterboard, ceilings and insulation), Oraé (glass), Enaé (mortars), EnviroMix and EnviroAdd (admixtures and additives to reduce the carbon footprint of concrete and cement);
• Constant innovation: climate-resilient offering in the US with the multi-product FORTIFIED Roof™ system; a patented process in Finland that replaces 70% of cement in mortars by steel slag and reduces CO2 emissions;
• Low- and zero-carbon plants (the only producer of plasterboard from fully electrified plants, in Norway and Canada) and promotion of circularity (recycling of construction and demolition waste for gypsum, glass wool, stone wool and glass), contributing to a 35% reduction in scope 1 & 2 CO2 emissions in 2025 compared with 2017, with 70% of decarbonized electricity in 2025 (versus 39% in 2021).

2025 Group operating performance

Sales rose 2.1% in local currencies and remained stable as reported at €46.5 billion, despite the depreciation in most currencies against the euro (negative 2.3% currency effect over the year and negative 3.0% in the second half).

The positive 2.6% structure impact results mainly from four recent acquisitions enhancing Saint‑Gobain’s profitable growth profile: CSR in Australia, Bailey in Canada, Cemix in Latin America and FOSROC in India and the Middle East. The optimization of the Group’s profile also continued with divestments, notably pipe for buildings (PAM Building), distribution in Belgium and Brazil, as well as dry mortars and off-site construction (Brüggemann) in Germany.

On a like-for-like basis, sales were virtually stable (down 0.5% for the year and down 0.4% in the second half), supported in the second half by good growth in Asia-Pacific and Latin America and a return to growth in Europe (driven by Southern Europe), despite the marked decline in North America.

Group prices were 0.8% higher over the year and 0.7% higher in the second half, generating a slightly positive price-cost spread for the year and in the second half, thanks to disciplined execution and the added value of our comprehensive, innovative and sustainable solutions. Volumes were down by 1.3% over the year and by 1.1% in the second half.

Operating income was €5,293 million, up 3.8% in local currencies. The operating margin was stable at 11.4% in 2025, despite the negative currency impact and a contrasted macroeconomic environment, reflecting the strength of the Group’s strategic positioning and a good operating performance. In the second half, the margin for the Americas held firm as expected at 16%, although the region’s contribution to Group operating income was lower in mass owing to a negative currency effect and the contraction in volumes; the margins for Europe and Asia-Pacific were up slightly.

EBITDA was €7,203 million, a rise of 3.4% in local currencies, with the EBITDA margin stable at 15.5%.

Performance by Region

Europe: return to sales and operating income growth in the second half

After a first half down around 2%, activity in Europe was up in the second half, rising 1.1% in local currencies and 0.6% like-for-like, marking a return to sales growth for the first time since second-half 2022, led by Southern Europe. The operating margin remained virtually stable over the year, at 8.5% versus 8.6% in 2024 (EBITDA margin at 12.6%), with 8.3% in the second half (8.2% in second-half 2024), supported by good cost and pricing management.

• Northern Europe decreased 0.4% like-for-like over the year, stable excluding industrial solutions, with a contrasted situation by country. The UK reported further growth, driven by a clear outperformance on the back of specified sales and its comprehensive solutions offering. Eastern Europe was up slightly, although Poland was impacted by the decline in industrial solutions. Germany remained down pending the implementation of its stimulus plan, with market statistics better oriented. Nordic countries remained mixed overall, with growth in Sweden and Denmark, which benefited from several infrastructure projects (e.g. Storstrøm bridge waterproofing), but with Norway and Finland still down. As lead solutions supplier, the Group helped an office and laboratory complex in Tromsø, Norway, secure the highest BREEAM certification (“Outstanding”), placing it as the sixth most sustainable building in the world. Thanks to its strong presence of over 100 plants in Central and Eastern Europe (representing over 10% of Group sales), Saint-Gobain is ideally placed to capitalize on major infrastructure and defense spending plans in the region.
• Southern Europe, Middle East & Africa improved noticeably in the second half, up 1.7%, but were down 1.1% like-for-like over the year. In a market that remains uncertain, France stabilized in the second half and reported growth in the fourth quarter (volumes up 1.0%), driven by an improvement in new construction; Saint-Gobain outperformed both the new construction and renovation markets thanks to its comprehensive range of innovative solutions and its specification model in non-residential markets. Spain and Italy progressed, particularly in interior solutions which continued to capture market share. The Middle East and Africa (representing 3% of Group sales) reported double-digit growth driven by the success of the FOSROC integration and major infrastructure projects – for example in Saudi Arabia (tunnels in Diriyah, wind farm in Dumat Al Jandal) and the United Arab Emirates (bridges and infrastructure connecting Ramhan Island to Abu Dhabi, the Dubai Metro Blue Line) – as well as residential and tourist complexes.

Americas: outperformance in the second half with a stable margin despite a marked decline in sales

The Region was up by 1.5% in local currencies over the year, but was down by 1.2% like-for-like owing to the slowdown in North America, partly offset by strong growth in Latin America. The operating margin rose slightly over the year to 17.2% from 16.8% in 2024 (EBITDA margin at 20.5%) and held firm at 16.0% in the second half (versus 16.2% in second-half 2024), supported by rigorous pricing and cost management despite the marked decline in volumes.

• North America was down by 4.2% like-for-like over the year and by 7.3% in the second half, with a fourth quarter of a similar magnitude, down 8.2%, outperforming its market. As expected, roofing volumes in the US remained weak in the fourth quarter (down 17%, in line with the 18% decline in the third quarter), reflecting the lack of major weather events. Interior solutions in the US and Canada continued to be affected by weakness in the new construction market, while construction chemicals showed clear growth and captured market share in the US, especially in additives and admixtures. Industrial solutions however experienced a more pronounced contraction in the fourth quarter. Against this backdrop, Saint-Gobain delivered a very good operating performance – margins held firm for the full-year and in the second half in North America – maintaining a positive price effect and optimizing its production, costs and industrial plant maintenance.

The Group also opened new cutting-edge production facilities in the US and Canada. On the commercial front, the Group leveraged its leadership position in interior and exterior solutions with its major distribution partners, and expanded in the non-residential (healthcare, education, data centers) and infrastructure markets: for example, Saint-Gobain specified 15 solutions for the new terminal at New York’s JFK airport, including differentiated waterproofing (Perm‑A‑Barrier®, PREPRUFE®, Bituthene®), electrochromic glass, ceilings, gypsum and insulation.

• Latin America was up by 13.5% over the year in local currencies and by 6.9% like-for-like, with the increase slowing in the second half (up 2.9%) against a tougher comparison basis and with a decrease in prices at the end of the period owing to lower energy costs; industrial solutions saw double-digit growth. Brazil reported further growth driven by market share gains in light construction thanks to its unrivalled range of solutions, helping to accelerate cross‑selling and grow its specified sales. The country also launched production of Latin America’s first low-carbon glass in the second half. The resounding success of the Cemix integration can be seen in growth of over 15% in local currencies, driving growth across the Group’s solutions in Mexico and Central America. Saint-Gobain participated in several landmark projects in the Region in the non-residential and infrastructure markets, including hotel complexes in Cancun, Mexico (Hyatt Vivid Grand Island, Shark Tower, Waldorf Astoria), a wind farm in Rio Grande do Sul, Brazil, and Line 7 of Santiago’s Metro in Chile.

Asia-Pacific: sales growth and record margin

The Region delivered growth for the year of 16.9% in local currencies and 2.4% like-for-like (3.4% in the second half), driven by the smooth integration of FOSROC and strong momentum in India. The operating margin hit a record high of 13.3% versus 13.0% in 2024 (EBITDA margin at 17.7%), mainly thanks to volumes along with good pricing and cost management.

India achieved further market share gains thanks to the success of its comprehensive range of construction solutions, which drove a double-digit rise in volumes. The Group was awarded new projects in non-residential and infrastructure, including Navi Mumbai airport and the Adani data center in Noida, confirming its leadership in construction chemicals thanks to the successful integration of FOSROC. Chryso in India developed an application powered by Artificial Intelligence (AI) that reduces the number of formula tests by 40%, enabling accelerated innovation. South‑East Asia was led by good momentum in Indonesia, the Philippines and Vietnam, where growth was boosted by a widened range of specified solutions, particularly for infrastructure projects (Long Thanh and Phu Quoc airports in Vietnam, Jakarta metro in Indonesia and Manilla metro in the Philippines) and data centers (around 20 in Indonesia and Malaysia in 2025). The integration of CSR in Australia is progressing well, in terms of both operational performance and the development of complete solutions, in a construction market that remains lackluster but whose leading indicators are improving. China was down slightly over the year but progressed in the second half, supported by industrial solutions and market share gains in gypsum and plasterboard, despite continued market weakness.

Analysis of the 2025 consolidated financial statements

The 2025 consolidated financial statements, audited and certified by the statutory auditors, were approved by Saint-Gobain’s Board of Directors on February 26, 2026.

1. Organic growth in 2021: +6.9% (+13.8% in 2021/2019 divided by 2)

EBITDA remained stable at €7,203 million, up 3.4% in local currencies, with the EBITDA margin stable at 15.5% despite the negative currency impact and mixed environment. Non-operating costs included in EBITDA fell slightly, at €231 million.

The net balance of capital gains and losses on disposals, asset write-downs and the impact of changes in Group structure represented an expense of €511 million (€691 million in 2024). It reflects €216 million in asset write-downs relating essentially to disposals and site closures (€291 million in 2024), €290 million in Purchase Price Allocation (PPA) intangible amortization (€233 million in 2024), and €5 million in disposal losses and impacts relating to changes in Group structure (€167 million in 2024).

Recurring net income was €3,309 million, affected by the rise in financial expenses. The tax rate on recurring net income was stable at 24%.

EPS increased by 2.5% and by 6.4% in local currencies.

Capital expenditure remained stable at €2,049 million. The Group continued to show solid momentum with 24 new plants and production lines opened in the year to respond to structural market growth in North America, Asia and emerging countries as well as in construction chemicals, which together account for around 80% of growth capex.

Free cash flow remained at a good level at €3,752 million. The conversion ratio at 58% reflects very good management of operating working capital requirement (WCR), which represented 11 days’ sales at end-2025 versus 12 days’ sales at end-2024.

ROCE was 14.0%, reflecting our focus on creating value for shareholders.

Investments in securities net of net debt acquired represented €1,885 million, corresponding mainly to the FOSROC (India, Middle East) and Cemix (Latin America) acquisitions in construction chemicals. Overall, the Group’s acquisitions in 2025 represent full-year sales of around €860 million and around €220 million of EBITDA (including synergies in year 3), corresponding to a multiple of around 8.5x EBITDA.

Divestments totaled €421 million and mainly reflected the disposal of the Badgerys Creek property in Australia for around €320 million (A$575 million) as part of the monetization of CSR’s property assets.

Net debt was €10.4 billion, with the net debt to EBITDA ratio stable at 1.4x at end-2025.

Attractive shareholder return policy

In 2025, the dividend paid and share buybacks carried out represented €1.5 billion:

• A dividend of €1,085 million was paid in respect of 2024;
• Share buybacks were carried out for €402 million in 2025 (net of employee share creation), reducing the number of shares outstanding to 493 million at end-2025 (497 million at end-2024).

Saint-Gobain’s Board of Directors decided to recommend to the Shareholders’ Meeting on June 4, 2026 the payment of a cash dividend up 4.5% to €2.30 per share for 2025 (€2.20 for 2024). The ex-dividend date has been set at June 8, 2026 and the dividend will be paid on June 10, 2026.

Strategic priorities

In 2026, the Group will focus on strong execution to decisively implement the strategic priorities of its “Lead & Grow” plan:

1. Outperform markets by 1 to 2 percentage points thanks to:
   • Saint-Gobain’s complete range of solutions offering customers performance and sustainability;
   • Country platforms based on local value chains, optimized by CEOs native to their country who are fully accountable for their perimeter;
   • An expanded presence in non-residential and infrastructure thanks to the development of tailored offers and dedicated teams for each end market (particularly hotels, data centers, healthcare and educational facilities, transport infrastructure);
   • Saint-Gobain’s industry-leading role as worldwide leader in light and sustainable construction.
2. Continue to pursue excellence in execution in order to deliver the Group’s ambitious trajectory, with an EBITDA margin of between 15% and 18% over the period 2026-2030 and a free cash flow conversion ratio above 50%, thanks to:
   • Disciplined management of the price-cost spread;
   • Strict measures to reduce costs and deliver productivity gains in order to proactively adapt to market conditions.
3. Continue to actively optimize the Group’s profile, with asset rotation to represent over 20% of sales by 2030, in terms of both acquisitions and divestments.
4. Disciplined capital allocation to deliver growth and value creation for shareholders:
   • Investments focused on consolidating leadership positions, high-growth countries and construction chemicals;
   • Capital expenditure around 4.5% of sales in 2026;
   • Attractive shareholder returns, targeting regular growth in dividends per share and €2 billion in net share buybacks (2026-2030).

2026 outlook

In a contrasted macroeconomic environment and uncertain geopolitical landscape, the Group expects the following trends for 2026:

• Europe: gradual improvement, with contrasted trends by country;
• North America: continued market weakness in the first half, gradually improving outlook in the second half with an easier comparison basis;
• Asia-Pacific and Latin America: growth led notably by India, South-East Asia and Mexico.

Saint-Gobain expects an EBITDA margin of more than 15.0% in 2026, with the first half affected by the extreme weather conditions in Europe and North America since the start of the year.
