Jan Jenisch, Chairman and CEO: "As our first full quarter operating as Amrize, we made progress across our business and I thank our 19,000 teammates for serving our customers across all of our markets.

"Together, we delivered strong revenue growth of 6.6% and Free Cash Flow generation of $674 million, up $221 million. Our Building Materials business had strong sales with increased customer demand, while margin was affected by a temporary equipment outage in our cement network. Within Building Envelope, operational efficiencies and lower raw material costs delivered margin expansion.

"This quarter, we made progress across our key organic growth investments and kicked off new projects to expand production and improve efficiency to serve our customers in attractive markets from Dallas-Fort Worth to Calgary.

"The actions we are taking from investing in our business to driving synergies with our ASPIRE program are positioning Amrize to capitalize on the significant, long-term demand in our $200 billion addressable market."

Amrize Consolidated Results

Revenues were $3,675 million in the third quarter of 2025 compared to $3,446 million in 2024. Revenues grew 6.6% in the quarter, including organic growth of 6.0% driven by volume growth in Building Materials and commercial roofing, combined with positive aggregates and shingles pricing. Infrastructure demand remained strong and the commercial market improved, while the residential market remained soft with lower new construction and a milder storm season.

Net income was $543 million for the third quarter of 2025, or $0.98 per share, compared with Net income of $552 million, or $1.00 per share, in 2024. Adjusted EBITDA was $1,067 million for the third quarter of 2025 compared with $1,103 million in 2024. Operational efficiencies and lower raw material costs in Building Envelope were offset by $50 million of higher manufacturing and distribution costs associated with a temporary equipment outage in the cement network. The third quarter of 2024 included $39 million of higher asset sales compared to the third quarter of 2025.

Amrize Building Materials Results

Building Materials Revenues were $2,774 million in the third quarter of 2025 compared to $2,551 million in 2024. Revenue growth of 8.7% in the quarter includes organic growth of 8.9%, which was primarily driven by strong volume growth across cement and aggregates, combined with positive aggregates pricing growth. Third quarter 2025 Revenues were supported by public infrastructure spending, and commercial investments in data centers and energy related projects.

Third quarter 2025 Adjusted EBITDA for the Building Materials segment was $902 million, compared to $942 million in 2024. The decrease was mainly attributable to $50 million of additional manufacturing and distribution costs associated with a temporary equipment outage in the cement network and lower cement pricing. The third quarter of 2024 included $39 million of higher asset sales compared to the third quarter of 2025.

The company is progressing with key organic growth projects to expand production and improve efficiency in attractive markets. It is on track to increase production and improve operational efficiency in the fourth quarter at its flagship Ste. Genevieve cement plant. In the third quarter, Building Materials kicked off new organic growth projects to increase aggregates production in the Great Lakes region and expand production and improve efficiency at its Midlothian, Texas and Exshaw, Alberta cement plants in the Dallas-Fort Worth and Calgary markets, respectively.

Amrize Building Envelope Results

Building Envelope Revenues were $901 million for the third quarter of 2025, compared to $895 million in 2024. Revenue growth of 0.7% was primarily driven by momentum in commercial roofing, repair & refurbishment demand and system sales. Building Envelope achieved revenue growth and market share gains in commercial roofing, while residential roofing was down due to softer new construction and a milder storm season. The Ox Engineered Products acquisition contributed an additional $26 million of revenue during the third quarter.

Third quarter 2025 Adjusted EBITDA for the Building Envelope segment was $217 million, compared to $199 million in 2024. Operational efficiencies and lower raw material costs resulted in 190 basis points of Adjusted EBITDA margin expansion.

The company is on track to open a new state-of-the-art Malarkey shingle factory in Indiana in the second half of 2026 to increase production and expand market share in the attractive Midwest and Eastern markets.

Amrize Cash Flow and Debt

In the third quarter of 2025, operating cash flow was $854 million and Free Cash Flow⁶ was $674 million, up $221 million from third quarter 2024. Higher Cash flow in the quarter was driven by positive working capital and lower cash tax payments partially offset by lower net income and higher CapEx.

Net cash provided from operating activities for the first nine months of fiscal year 2025 was $404 million compared to $555 million for the first nine months of 2024. Lower Net income and working capital timing were the primary drivers of the year-over-year change in cash provided by operating activities. Capital expenditures for the first nine months of fiscal year 2025 totaled $631 million compared to $558 million in the prior year, reflecting an increase in growth investments across the business.

Gross Debt at the end of the third quarter of 2025 was $5,811 million. Cash and cash equivalents were $826 million, resulting in a decrease in Net Debt⁷ to $4,985 million, compared to $5,597 million in the second quarter of 2025. Improved Net Debt was driven by higher free cash flow enabling the company to repay $385 million of commercial paper in the third quarter of 2025. The Net Leverage Ratio⁸ at the end of the third quarter of 2025 was 1.7x, compared to 1.8x in the second quarter of 2025.

Non-GAAP financial measures are reconciled to the most comparable U.S. GAAP measures in the schedules attached hereto. Adjusted financial measures are Non-GAAP measures and exclude adjusting items as described and reconciled to comparable U.S. GAAP financial measures in the Reconciliation of U.S. GAAP to Non-GAAP Financial Measures contained in this Media Release.

We believe these adjusted financial measures facilitate analysis and comparisons of our ongoing business operations because they exclude items that may not be indicative of, or are unrelated to, the company's and our business segments' core operating performance, and may assist investors with comparisons to prior periods and assessing trends in our underlying businesses. These adjustments are consistent with how management views our businesses. Management uses these non-GAAP financial measures in making financial, operating and planning decisions and evaluating Amrize's and each business segment's ongoing performance.

Our non-GAAP financial measures are intended to supplement and should be read together with, and are not an alternative or substitute for, and should not be considered superior to, our reported financial results. Accordingly, users of our financial statements should not place undue reliance on these non-GAAP financial measures. Because non-GAAP financial measures are not standardized, it may not be possible to compare these financial measures with other companies' non-GAAP financial measures having the same or similar names. As required by SEC rules, the tables on pages 13 and 14 below present a reconciliation of our presented non-GAAP financial measures to the most directly comparable GAAP measures.
