In the second quarter, we successfully navigated a challenging environment, generating stable revenue and strong margins showing the resilience and strength of our business and market positions.

With an investment grade balance sheet and substantial financial firepower to fuel our growth, we are ready to deliver superior value to all stakeholders.

I thank our 19,000 Amrize teammates across North America who are delivering for our customers and empowering our growth in every U.S. state and Canadian province."

Expanding Margins with the ASPIRE Program

Amrize launched its ASPIRE program to accelerate synergies and profitable growth. Leveraging its scale across 1,000 sites and two business segments, Amrize is optimizing third party spending and driving efficiencies in its operational footprint and logistics network.

With the ASPIRE program, Amrize is targeting more than $250 million in synergies through 2028, delivering over 50 basis points of margin improvement per year. The company expects to begin achieving incremental savings in the second half of 2025, with the full annual savings run rate starting in 2026.

Investing for Growth

Amrize continued to invest for growth through CapEx and value accretive M&A. Highlights include:

• Acquired the operations of Langley Concrete Group, Inc., expanding the company's precast concrete footprint with two state-of-the-art facilities in British Columbia and strengthening its market position in Canada's rapidly growing infrastructure sector.

• Opened a greenfield quarry in Oklahoma with 200 million tons of reserves expanding the company's strong aggregates business serving the fast growing Dallas-Fort Worth market.

• On track to add 660,000 tons of cement capacity and improve manufacturing efficiency by the end of this year at the company's flagship cement plant in Missouri, North America's largest and market-leading cement plant.

• Broke ground on a new fly ash beneficiation facility in Virginia, to enable the use of recycled, landfilled ash as a high-quality supplementary cementitious material.

• On track to complete construction and open a new state-of-the-art Malarkey shingle factory in Indiana in the second half of 2026 to increase production capacity by over 50% and expand market share in the attractive Midwest and Eastern markets.

• On track with expansion of the St. Constant cement plant in Quebec to increase capacity by 300,000 tons, improve manufacturing efficiency and strengthen Amrize's market position in Canada.

Established Investment-Grade Balance Sheet

Amrize has established a strong balance sheet and capital structure. In the second quarter, the company successfully secured $5.3 billion of senior notes, and $930 million of short-term borrowings under the company's $2 billion commercial paper program.

Cash and cash equivalents were $601 million as of June 30, 2025, resulting in Gross Debt balance of $6.2 billion and a Net Debt¹ balance of $5.6 billion and a Net Leverage Ratio² of 1.8x. The company expects to achieve a Net Leverage Ratio of below 1.5x by the end of the year.

S&P Global Ratings and Moody's Ratings have rated Amrize investment grate at BBB+ and Baa1, respectively, with a stable outlook.

With its strong balance sheet and cash generation, Amrize will maintain a growth-focused capital allocation strategy to prioritize investments in the business, value accretive M&A and shareholder returns.

Revenues were stable at $3,220 million in the second quarter of 2025 compared to $3,243 million in 2024, highlighting resilient performance in a challenging market environment with inclement weather in the quarter. Public sector spending resulted in steady infrastructure demand during the quarter. Commercial customers continued executing on larger projects, while market uncertainty has impacted the timing of capital spending for new project starts. Higher interest rates limited existing home sales and new construction in the residential market.

Net income was $428 million for the second quarter of 2025, or $0.78 diluted earnings per share, compared with Net income of $473 million, or $0.86 diluted earnings per share, for the second quarter of 2024. Adjusted EBITDA was $947 million for the second quarter of 2025 compared with $1,003 million in the second quarter of 2024. Second quarter results include an additional $42 million of standalone corporate costs that are not reflected in second quarter 2024 Adjusted EBITDA. Excluding these standalone corporate costs, margins were stable during a period of softer market volumes.

Building Materials Revenues were $2,250 million in the second quarter of 2025 compared to $2,274 million in 2024. Second quarter 2025 Revenues were supported by public infrastructure spending, strong commercial investments in energy infrastructure and mega-projects. Market uncertainty and inclement weather affected the timing of new commercial and residential construction starts, with volumes improving as the quarter progressed.

Cement volumes for the second quarter decreased 6.3%, while the average sales price per ton of cement increased 0.5%. Aggregates volumes decreased 2.9%, while the average sales price per ton of aggregates increased 6.7%. Pricing was driven by strong infrastructure spending and Amrize's market-leading positions and unparalleled footprint.

Second quarter 2025 Adjusted EBITDA for the Building Materials segment was $758 million, compared to $770 million in 2024. Disciplined pricing, operational performance and a highly efficient distribution and logistics network resulted in strong margin performance even in a challenging market environment.

Long term market growth is expected to be driven by infrastructure modernization, onshoring of manufacturing, data center expansion and the need to bridge the housing gap.

Executing on its growth strategy, the company acquired the operations of Langley Concrete Group, Inc., expanding its market position in Canada, and opened a greenfield aggregates quarry in Oklahoma to serve the fast growing Dallas-Fort Worth market. Amrize is also on track with key CapEx investments to expand capacity and improve efficiency across its market-leading cement plants, including at Amrize's flagship Ste. Genevieve plant, North America's largest and market-leading cement plant.

Building Envelope Revenues were $970 million for the second quarter of 2025, compared to $969 million in 2024. The increase in Revenues was driven by the acquisition of Ox Engineered Products, which contributed $33 million in Revenues. Higher interest rates continued to limit new construction and the housing market, while the repair and refurbishment market continues to provide steady demand.

Second quarter 2025 Adjusted EBITDA for the Building Envelope segment was $261 million, compared to $263 million in 2024. Disciplined pricing and effective cost management in a challenging environment helped offset softer residential demand and enabled the company to deliver stable margins for the quarter.

Long term market growth is expected to be driven by single-family and multi-family residential building to bridge the housing gap, data center expansion, onshoring of manufacturing and expansion of logistics and warehousing.

Investing for growth, 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 capacity and expand market share in the attractive Midwest and Eastern markets.
