Amrize Reports Third Quarter 2026 Results • Revenues up 2.2% to $3,771 million • Net Income grew 3.3% to $558 million • Adjusted EBITDA increased 0.2% to $1,076 million • Margin expansion of 30 basis points in Building Materials • Completed Rapid Redi-Mix acquisition in Dallas-Fort Worth • Board of Directors declared third quarter dividend of $0.11 per share • FY 2026 Guidance updated reflecting continued cost inflation and elevated interest rates CHICAGO/ZUG, Switzerland, October 28, 2026 – Amrize (AMRZ) announced today its third quarter 2026 financial results. Jan Jenisch, Chairman and CEO: "With the strength of our network and strategic footprint, we delivered resilient results in the third quarter. We increased revenue 2.2% on strong pricing and contributions from our recent acquisitions, even as weather patterns affected construction in the quarter. We grew Net Income by 3.3% to $558 million and increased Adjusted EBITDA to $1,076 million. While oil price driven cost inflation continued to affect the industry, we're proactively managing what we can control and achieved strong gains in pricing, surcharges and our ASPIRE program. In the third quarter, cement pricing increased 1.8% and aggregates prices grew 6.9% driving margin expansion of 30 basis points in Building Materials. We achieved positive price traction in commercial and residential roofing in Building Envelope. In addition to pricing, our energy, fuel and freight surcharges contributed $23 million across our business. We continued to drive synergies with our ASPIRE program and have now delivered $73 million in savings year-to-date. We are executing on our strategy of investing for profitable growth in attractive markets, while returning cash to shareholders. We invested $262 million in Capex as we expand production and improve efficiency to best serve our customers. Our recent acquisitions PB Materials and Rapid Redi-Mix are exceeding our expectations and are expected to be EPS accretive this year. While inflation and interest rates continue to be a headwind for full year results, mega-trends from data centers and energy projects to advanced manufacturing and infrastructure are expected to continue driving long term construction demand. With our unparalleled footprint across North America, we are well positioned to serve our customers, deliver profitable growth and return value to our shareholders." Shareholder Return Amrize has returned $1.1 billion to shareholders with share buybacks and dividends in the first three quarters. The company repurchased $750 million of Amrize shares in the first three quarters. On October 28, 2026, the company completed its $1 billion share repurchase program, representing approximately 4% of the share capital. Amrize has paid $364 million of dividends year to date, including the special one time dividend for 2025 and quarterly dividends for the first and second quarters of 2026. The Amrize Board of Directors declared a dividend of $0.11 per share for the third quarter to be paid on November 18, 2026. The last trading day with entitlement to receive the quarterly dividend, known as the cum-dividend date, is November 9, 2026. The shares will be traded ex-dividend on November 10, 2026, which is also the record date. Dividends are paid out of capital contribution reserves1 and are not subject to Swiss withholding tax. Media Release Ad hoc announcement pursuant to Art. 53 LR Media Relations: media@amrize.com Investor Relations: investors@amrize.com 1 1 Dividends will be made in the form of distributions paid out of legal reserves from capital contributions and are not subject to Swiss withholding tax. The dividend is the third installment of the annual dividend of up to $0.44 per share approved at the Company's 2026 Annual General Meeting.
Full Year 2026 Financial Guidance2 Building Materials had a strong first nine months of the year with revenue growth of 6.2% and Adjusted EBITDA growth of 5.5%. Weather patterns moderated volumes in the third quarter and elevated interest rates may affect fourth quarter volumes. For the full year, we continue to expect cement pricing to be flat to up low-single digits and aggregates pricing to be up mid-single digits. Energy, fuel and freight surcharges have helped offset cost inflation, and the company expects Building Materials to be price-cost positive in Q4 2026. Building Envelope increased revenue 2.0% in the first nine months. The company expects commercial roofing volumes to remain resilient and residential roofing to be softer due to lower existing-home sales. Price increases are phasing in across the Building Envelope portfolio, as well as freight and fuel surcharges to offset cost inflation. The company expects price-cost to improve sequentially in Q4 2026 compared to Q3 2026. However, the magnitude of inflation has pushed the company's expectation for Building Envelope price-cost positivity into 2027. The ASPIRE program continues to execute with $73 million savings achieved across raw materials, service, logistics and equipment spend in the first nine months of the year. The program is on track to achieve $80 million of savings in 2026. Insurance proceeds of $36 million recognized in the Building Materials segment during Q4 2025 are not expected to repeat this year. Based on these drivers, Amrize is updating its FY 2026 financial guidance as follows: Revenues $12.2 billion to $12.4 billion Adjusted EBITDA $2.95 billion to $3.05 billion The company's 2026 financial guidance now includes the following underlying assumptions: Capital Expenditures ~$900 million Interest Expense, Net ~$340 million Adjusted Effective Tax Rate 23% - 25% Corporate Costs ~$200 million Media Release Ad hoc announcement pursuant to Art. 53 LR Media Relations: media@amrize.com Investor Relations: investors@amrize.com 2 2 Amrize provides forward-looking guidance regarding Adjusted EBITDA. Amrize cannot, without unreasonable effort, forecast certain adjusted items excluded from comparable U.S. GAAP financial measures. These items include Acquisition and integration-related costs, Litigation-related costs, Loss on impairments, Restructuring and other costs, Spin-off and separation-related costs, Other non-operating income, net, and Income from equity method investments, that are difficult to predict in advance to include in a U.S. GAAP estimate. For the same reasons, Amrize is unable to address the probable significance of the items.

Revenues were 2.2% higher in the quarter, primarily driven by price increases of $78 million, contributions from acquisitions of $77 million, and surcharges of $23 million, partially offset by lower volumes and the unfavorable impact of foreign exchange and other revenues. Net income was $558 million for the third quarter of 2026, or $1.02 per diluted share, compared with Net income of $540 million, or $0.98 per diluted share, in the third quarter of 2025. Adjusted diluted earnings per share for the third quarter of 2026 was $1.05 compared to $1.05 in the third quarter of 2025. Adjusted EBITDA was $1,076 million for the third quarter of 2026 compared to $1,074 million in 2025. The increase was driven by price increases, surcharges, and contributions from acquisitions, partially offset by higher freight, diesel and raw material costs and lower volumes. Adjusted EBITDA Margin was 28.5% for the three months ended September 30, 2026, compared to 29.1% for the three months ended September 30, 2025. Unallocated corporate costs in the third quarter of 2026 were $44 million compared to $52 million in the third quarter of 2025.

The increase was driven by pricing growth, contributions from acquisitions and surcharges, which was partially offset by lower volumes and the unfavorable impact of foreign exchange. Cement volumes were down 4.2% and aggregates volumes were down 0.2% due to weather in the Northeast, South and Central regions, partially offset by steady state and federally funded multi-year projects. Cement pricing was up 1.8% on a constant currency basis compared to the third quarter of 2025 and aggregates pricing grew 6.9%. In addition to pricing, energy, fuel and freight surcharges contributed to the quarter. Third quarter 2026 Segment Adjusted EBITDA for Building Materials was up 2.7% to $938 million, compared to $913 million in 2025. The increase was driven by price increases, contributions from acquisitions, and surcharges, which was partially offset by higher freight and diesel costs.

Amrize Building Envelope Results (Unaudited) For the three months For the nine months ended September 30, ended September 30, $ in millions 2026 2025 % Change 2026 2025 % Change Revenues $ 929 $ 897 3.6% $ 2,656 $ 2,604 2.0% Segment Adjusted EBITDA $ 182 $ 213 (14.6%) $ 499 $ 586 (14.8%) Segment Adjusted EBITDA margin 19.6% 23.7% (410bps) 18.8% 22.5% (370bps) Building Envelope Revenues were $929 million for the third quarter of 2026, compared to $897 million in 2025. Revenue growth of 3.6% in the third quarter of 2026 was primarily driven by higher volumes and pricing. Commercial roofing volumes remained strong, led by expanded system sales, large-scale data centers and industrial projects. Commercial re-roofing demand remained resilient. Shingle volumes were impacted by lack of significant storms and sluggish existing-home sales, driving lower re-roofing demand. Pricing improved sequentially and year-over-year as price increases were phased in throughout the third quarter of 2026. In addition to pricing, fuel and freight surcharges contributed to the quarter. Third quarter 2026 Segment Adjusted EBITDA for the Building Envelope segment was $182 million, compared to $213 million in 2025. The decrease in Segment Adjusted EBITDA was primarily attributable to higher freight and raw material costs, partially offset by the benefit from improved volumes, pricing, and fuel and freight surcharges.

Amrize Cash Flow and Debt For the nine months ended September 30, 2026, net cash provided by operating activities was $222 million compared to $417 million for the nine months ended September 30, 2025. The decrease in cash provided by operating activities of $195 million was primarily driven by net working capital changes and the settlement of Spin-Off related balances in the prior period, partially offset by higher net income and non-cash expenses. Free Cash Flow11 was a use of $551 million for the nine months ended September 30, 2026 compared to a use of $186 million for the nine months ended September 30, 2025. The decrease in Free Cash Flow was primarily driven by lower cash provided by operating activities and higher Capex investments for growth initiatives. Free Cash Flow is historically seasonal and the company generates the majority of its cash flow in the second half of the year. Gross Debt was $5,848 million and Cash and cash equivalents were $299 million as of September 30, 2026, resulting in Net Debt12 of $5,549 million. The Net Leverage Ratio13 as of September 30, 2026 was 1.8x.

FINANCIAL MEASURES AND DEFINITIONS This media release contains certain financial measures of historical performance and financial positions that are not prepared in accordance with U.S. generally accepted accounting principles ("U.S. GAAP").

Adjusted financial measures are Non-GAAP financial 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.

For the U.S. GAAP to Adjusted diluted earnings per share reconciliation adjusted items are shown net of tax in aggregate of $5 million and $12 million for the three months ended September 30, 2026 and 2025, respectively, and in aggregate of $16 million and $27 million for the nine months ended September 30, 2026 and 2025, respectively, based on applying the statutory tax rate for the jurisdictions in which the adjustment occurred or, by adjusting the tax effect to consider the impact of applying an annual effective tax rate on an interim basis. For purposes of reconciling adjusted diluted earnings per share with respect to taxes period-over-period, the company utilizes a “rate approach” to highlight the impact of the adjusted tax rate. It is computed by multiplying the prior period adjusted rate by the current period adjusted income before taxes to determine the expected tax expense. Such expected tax expense is then compared to actual tax expense. Expected tax in excess of actual tax variance is favorable; actual tax in excess of expected tax variance is unfavorable. The variance divided by diluted shares outstanding at the end of the period yields the impact on earnings per share. Management believes the use of this measure best aids in explaining the impact of a changing tax rate.
