Management believes the organic revenue growth measure provides users with useful supplemental information regarding the Company’s ongoing revenue performance and trends by presenting revenue growth excluding the impact of foreign exchange as well as the impact of acquisitions and divestitures. “Constant Currency Price per Ton” is defined as price per ton adjusted to prior period foreign exchange rates, which is intended to eliminate the impact of foreign currency exchange rate fluctuations. Constant currency measures are calculated by translating local currency financial results into U.S. Dollars using the weighted-average exchange rates in effect during the comparable period. Management believes constant currency performance metrics provide useful supplemental information to investors by isolating underlying operational trends from foreign currency volatility.

We earn revenue from the sale of cement, aggregates, ready-mix concrete, asphalt, roofing systems, and other building solutions. We operate in two reportable segments, offering a complete range of advanced solutions to support large-scale and complex construction projectsprojects, fromsuch as bridges toand data centerscenters, in the areas of residential, commercial, and infrastructure construction.

Our Building Materials segment operating results for the first and fourth quarters are generally lower than those for the second and third quarters, which benefit from more favorable weatherweather, and increased construction activity. In addition to impacting demand, adverse weather can disrupt production schedules, shipments, and project timelines, affecting costs, efficiencies, and profitability. We manage these seasonal fluctuations through operational planning and flexible workforce management, but quarter-to-quarter results may not be indicative of full-year performance.

We operate in competitive markets with respect to each of our segments. Recent market conditions, such as trade policy uncertainty, energy market disruptions, geopolitical conflicts, fluctuations in interest rates, and construction market labor challenges may impact various markets in which we operate. While ourOur Building Envelope segment has been impacted by these market conditions,conditions. However, our Building Materials segment has remained resilient,resilient asby we have been able to leverageleveraging our scale, unique footprint, and diverse product offerings to customers. We expect the execution of our ASPIRE program to accelerate synergies and profitable growth, by investing in streamlining our network. Over the long term, we expect growth in demand due to urbanization, aging infrastructure, recent onshoring trends, population growth, and historical underinvestment in residential housing. As market conditions evolve, we believe that we are uniquely positioned to capitalize on these growth opportunities.

Emphasis on Building Envelope. Our strong presence in the Building Materials category has allowed us to acquire additional product lines, such as roofing and insulation products, in the Building Envelope segment. By acquiring Firestone Building Products (later renamed to Elevate Commercial Roofing Systems) in 2021, Herbert Malarkey Roofing Company (“Malarkey”) in 2022, and Duro-Last, LLC, Critical Point, LLC, Oscoda Plastics, LLC, Plastatech Engineering Limited, LLC, Anvil Paints & Coatings, LLC and Tip-Top Screw Manufacturing, LLC (collectively, “Duro-Last”) in 2023, we bolstered our roofing system offerings and positioned ourselves to meet growing demand for re-roofing and new builds. Our Building Envelope segment accounted for 31.1%30.0% and 36.1%30.4% of our revenues for the three and six months ended MarchJune 31,30, 20262026, compared to 29.8% and 32.2% for the three and six months ended June 30, 2025, respectively. We intend to continue building out our Building Envelope segment through expansions, acquisitions, and development of additional solutions and products, as we believe this will unlock long-term value creation. Such expansions and acquisitions depend on our ability to raise capital and seamlessly integrate new products into our current product mix.

Infrastructure Investment. Demand for our products is directly related to the level of activity in the construction industry, which includes residential, commercial and infrastructure construction. A recent focus on improving infrastructure in North America is being fueled by, among other things, funding from federal, state and local governments who are focused on addressing aging infrastructure across North America. We are leveraging our market position across North America and diverse product offerings to secure our involvement in airport, highway, bridgebridge, digital, and related infrastructure projects. Our ability to capitalize on this growing need for infrastructure-related projects across North America has the capability to increase our scope of operations and revenues.

Innovation. Through our research and development engine, we seek to drive cutting-edge innovation to address our customers’ greatest ambitions.needs. We believe we are at the forefront of new product developments, and our experts span all building fields, from masons and engineers to material scientists and experts in artificial intelligence and data mining. We conduct cutting-edge research and empower smart design while deploying new building technologies. We also partner with leading construction sector startups to scale up new technologies across our operations. Maintaining this level of innovation requires us to spend a substantial amount on research and development efforts, as well as on retaining and recruiting talent. Whether this spending results in increased revenue and more profitable operations will depend on our ability to introduce new products and improve our current product offerings. Although we will strive to introduce new products and to develop and market new construction techniques and technologies, our efforts may be unsuccessful or unprofitable resulting in impairments, which could negatively affect our results of operations and market positions.

The increase in our overall revenues was primarily driven by volume growth of $79 million and contributions from acquisitions of $24 million from our Building Materials segment. These factors were partially offset by lower market demand as well as lower prices of $24 million within our Building Envelope segment. Foreign exchange benefitted Amrize by $18 million for the quarter, as the Canadian dollar strengthened against the U.S. dollar.

Net Income and Net Income Margin

Added

Net income for the three months ended June 30, 2026 increased to $476 million from $416 million for the three months ended June 30, 2025. The increase was driven by the benefit from higher volumes, aggregates price increases, lower interest expense, lower corporate costs, and the contribution from acquisitions. These drivers were partially offset by higher operating costs, notably higher freight, diesel, and raw material costs within both segments, as well as higher depreciation, depletion, accretion and amortization expense.
