The information included in this presentation contains forward-looking statements within the meaning of Section 27A of the U.S. Securities Act of 1933, as amended, and Section 21E of the U.S. Securities Exchange Act of 1934, as amended. We intend these forward-looking statements to be covered by the “safe harbor” provisions for forward-looking statements within the meaning of the U.S. Private Securities Litigation Reform Act of 1995. These forward-looking statements and information are necessarily subject to risks, uncertainties, and assumptions, including but not limited to statements related to Cemex’s plans, objectives, goals, targets, and expectations (operative, financial or otherwise), and typically can be identified by the use of words such as, but not limited to, “will,” “may,” “assume,” “might,” “should,” “could,” “continue,” “would,” “can,” “consider,” “anticipate,” “estimate,” “expect,” “envision,” “plan,” “believe,” “foresee,” “predict,” “potential,” “target”, “goal”, “strategy,” “intend,” “aimed”, or other forward-looking words. These forward-looking statements reflect, as of the date such forward-looking statements are made, unless otherwise indicated, our current expectations and projections about future events based on our knowledge of present facts and circumstances and assumptions about future events. Although Cemex believes that its expectations are reasonable, it can give no assurance that these expectations will prove to be correct, and actual results may vary, including materially from historical results or those anticipated by forward-looking statements due to various factors. Among others, such risks, uncertainties, assumptions, and other important factors that could cause results and any guidance presented in this presentation to differ, or that otherwise could have an impact on us, include those discussed in Cemex’s most recent annual report and those detailed from time to time in Cemex’s other filings with the U.S. Securities and Exchange Commission (“SEC”), the Mexican National Banking and Securities Commission (Comisión Nacional Bancaria y de Valores) and the Mexican Stock Exchange (Bolsa Mexicana de Valores), which factors are incorporated herein by reference, including, but not limited to: changes in general economic, political and social conditions, including new governments and decisions implemented by such new governments, changes in laws or regulations in the countries in which we do business, elections, changes in inflation, interest and foreign exchange rates, employment levels, population growth, any slowdown in the flow of remittances into countries where we operate, consumer confidence and the liquidity of the financial and capital markets in Mexico, the United States of America, the European Union (the “EU”), the United Kingdom, or other countries in which we operate;

the increasing reliance on information technology infrastructure for our sales, invoicing, procurement, financial statements, and other processes that can adversely affect our sales and operations in the event that the infrastructure does not work as intended, experiences technical difficulties, or is subjected to invasion, disruption, or damage caused by circumstances beyond our control, including cyber-attacks, catastrophic events, power outages, natural disasters, computer system or network failures, or other security breaches; the effects of climate change, in particular reflected in weather conditions, including but not limited to excessive rain and snow, shortage of usable water, wildfires and natural disasters, such as earthquakes, hurricanes, tornadoes and floods, that could affect our facilities or the markets in which we offer our products and services or from where we source our raw materials;

declarations of insolvency or bankruptcy, or becoming subject to similar proceedings; natural disasters and other unforeseen events (including global health hazards such as COVID-19); and our ability to implement our “Future in Action” climate action program and achieve our sustainability goals and objectives. Many factors could cause Cemex’s expectations, expected results, and/or projections expressed in this presentation not being reached and/or not producing the expected benefits and/or results, as any such benefits or results are subject to uncertainties, costs, performance, and rate of success and/or implementation of technologies, some of which are not yet proven, among other factors. Should one or more of these risks or uncertainties materialize, or should underlying assumptions prove incorrect, actual results may vary materially from historical results, performance, or achievements and/or results, performance or achievements expressly or implicitly anticipated by the forward-looking statements, or otherwise could have an impact on us or our consolidated entities. Forward-looking statements should not be considered guarantees of future performance, nor the results or developments are indicative of results or developments in subsequent periods. Actual results of Cemex’s operations and the development of market conditions in which Cemex operates, or other circumstances that may materialize, may differ materially from those described in, or suggested by, the forward-looking statements contained in the information disclosed in this presentation. Any or all of Cemex’s forward-looking statements may turn out to be inaccurate and the factors identified above are not exhaustive. Accordingly, undue reliance on forward-looking statements should not be placed, as such forward-looking statements speak only as of the dates on which they are made. The forward-looking statements and the information contained in this presentation are made and stated as of the dates specified in this presentation and are subject to change without notice, and except to the extent legally required, we expressly disclaim any obligation or undertaking to update or correct the information contained in this presentation or revise any forward-looking statements in this presentation, whether to reflect new information, the occurrence of anticipated or unanticipated future events or circumstances, any change in our expectations regarding those forward-looking statements, any change in events, conditions, or circumstances on which any such statement is based, or otherwise. Readers should review future reports filed or furnished by us with the SEC, the Mexican National Banking and Securities Commission (Comisión Nacional Bancaria y de Valores) and the Mexican Stock Exchange (Bolsa Mexicana de Valores). Market data used in this presentation not attributed to a specific source are estimates of Cemex and have not been independently verified. Certain financial and statistical information contained in this presentation is subject to rounding adjustments. Accordingly, any discrepancies between the totals and the sums of the amounts listed are due to rounding. Unless otherwise specified, all references to records are internal records. This presentation includes certain non-International Financial Reporting Standards (“IFRS”) financial measures that differ from financial information presented by Cemex in accordance with IFRS in its financial statements and reports containing financial information. The aforementioned non-IFRS financial measures include “Operating EBITDA” (operating earnings before other expenses, net plus depreciation and amortization) and “Operating EBITDA Margin” (Operating EBITDA for the period divided by our revenues as reported in our financial statements). The closest IFRS financial measure to Operating EBITDA is “Operating earnings before other expenses, net”, as Operating EBITDA adds depreciation and amortization to the IFRS financial measure. Our Operating EBITDA Margin is calculated by dividing our Operating EBITDA for the period by our revenues as reported in our financial statements. We believe there is no close IFRS financial measure to compare Operating EBITDA Margin. These non-IFRS financial measures are designed to complement and should not be considered superior to financial measures calculated in accordance with IFRS. Although Operating EBITDA and Operating EBITDA Margin are not measures of operating performance, an alternative to cash flows or a measure of financial position under IFRS, Operating EBITDA is the financial measure used by Cemex’s management to review operating performance and profitability, for decision-making purposes and to allocate resources. Moreover, our Operating EBITDA is a measure used by Cemex’s creditors to review our ability to internally fund capital expenditures, service or incur debt and comply with financial covenants under our financing agreements. Furthermore, Cemex’s management regularly reviews our Operating EBITDA Margin by reportable segment and on a consolidated basis as a measure of performance and profitability. These non-IFRS financial measures do not have any standardized meaning and are therefore unlikely to be comparable to similarly titled measures presented by other companies. Non-IFRS financial measures presented in the presentation are being provided for informative purposes only and shall not be construed as investment, financial, or other advice. Also, this presentation includes statistical data regarding the production, distribution, marketing and sale of cement, ready-mix concrete, clinker, aggregates, and Urbanization Solutions. Cemex generated some of this data internally, and some was obtained from independent industry publications and reports that Cemex believes to be reliable sources. Cemex has not independently verified this data nor sought the consent of any organization to refer to their reports in this presentation. Cemex acts in strict compliance of antitrust laws and as such, among other measures, maintains an independent pricing policy that has been independently developed and its core element is to price Cemex’s products and services based upon their quality and characteristics as well as their value to Cemex’s customers. Cemex does not accept any communications or agreements of any type with competitors regarding the determination of Cemex’s prices for Cemex’s products and services. Unless the context indicates otherwise, all references to pricing initiatives, price increases or decreases, refer to Cemex’s prices for Cemex’s products. The information, statements, and opinions contained in this presentation do not constitute a public offer under any applicable legislation, an offer to sell, or solicitation of any offer to buy any securities or financial instruments, or any advice or recommendation with respect to such securities or other financial instruments. Cautionary Statement Regarding Environmental, Social, and Governance (“ESG”) and Sustainability-Related Data, Metrics, and Methodologies This presentation includes non-financial metrics, estimates, or other information related to ESG and sustainability matters that are subject to significant uncertainties, which may include the methodology, collection, and verification of data, various estimates, and assumptions, and/or underlying data that is obtained from third parties, some of which cannot be independently verified. The preparation of certain information on ESG and sustainability matters contained in the presentation requires the application of a number of key judgments, assumptions, and estimates. The reported measures reflect good faith estimates, assumptions, and judgments at the given point in time. There is a risk that these judgments, estimates, or assumptions may subsequently prove to be incorrect and/or, to the extent legally required, may need to be restated or changed. In addition, the underlying data, systems, and controls that support non-financial reporting are generally considerably less sophisticated than the systems and internal control for financial reporting and rely on manual processes. This may result in non-comparable information between organizations and/or between reporting periods within organizations as methodologies continue to develop and/or be socialized. The further development of or changes to accounting and/or reporting standards could materially impact the performance metrics, data points, and targets contained in the presentation, and the reader may not be able to compare non-financial information performance metrics, data points, or targets between reporting periods on a direct like-for-like basis. Additionally, the information disclosed in this presentation contains references to “green,” “social,” “sustainable,” or equivalent-labelled activities, products, assets, or projects. There is currently no single globally recognized or accepted, consistent, and comparable set of definitions or standards (legal, regulatory, or otherwise) of, nor widespread cross-market consensus i) as to what constitutes, a “green”, “social”, or “sustainable” or having equivalent-labelled activity, product, or asset; or ii) as to what precise attributes are required for a particular activity, product, or asset to be defined as “green”, “social”, or “sustainable” or such other equivalent label; or iii) as to climate and sustainable funding and financing activities and their classification and reporting. Therefore, there is little certainty, and no assurance or representation is given that our activities, products, or assets and/or reporting of such activities and/or reporting of those activities, products, or assets will meet any present or future expectations or requirements for describing or classifying such activities, products, or assets as “green”, “social”, or “sustainable” or attributing similar labels. We expect policies, regulatory requirements, standards, and definitions to be developed and continuously evolve over time. Cautionary Statement Regarding Forward-Looking ESG or Sustainability Statements Certain sections in the presentation contain ESG- or sustainability-related forward-looking statements, such as aims, ambitions, estimates, forecasts, plans, projections, targets, goals and other metrics, including but not limited to: climate and emissions, Business and Human Rights, corporate governance, Research and Development (“R&D”) and partnerships, development of products and services that intend to address sustainability-related concerns and sustainability related targets/ ambitions when finalized, including the implementation of technologies and other initiatives that aim to reduce and/or capture CO2 emissions. These forward-looking statements also include references to specific programs, such as our “Future in Action” climate action program, as well various ESG-related indicators, objectives or metrics disclosed previously or that may be disclosed in the future, none of which are guarantees and any and all of which may ultimately not be achieved or may be abandoned at any time, whether in part, in full, or within any specific timeframe. There are many significant uncertainties, assumptions, judgements, opinions, estimates, forecasts and statements made of future expectations underlying these forward-looking statements which could cause actual results, performance, outcomes or events to differ materially from those expressed or implied in these forward-looking statements, which include, but are not limited to: the extent and pace of climate change, including the timing and manifestation of physical and transition risks; the macroeconomic environment; uncertainty around future climate-related policy, including the timely implementation and integration of adequate government policies; the effectiveness of actions of governments, legislators, regulators, businesses, investors, customers, and other stakeholders to mitigate the impact of climate and sustainability-related risks; changes in customer behavior and demand, changes in the available technology for mitigation and the effectiveness of any such technologies, as some of these new technologies may be unproven; the roll-out of low carbon infrastructure; the availability and adoption of renewable energy within in our value chain; the development of carbon capture, circular utilization, and sequestration technologies, including the adoption of cost-effective carbon-related technologies such as carbon capture, utilization, and storage (“CCUS”); the availability of accurate, verifiable, reliable, consistent, and comparable climate-related data; lack of transparency and comparability of climate-related forward-looking methodologies; variation in approaches and outcomes, as variations in methodologies may lead to under or overestimates and consequently present exaggerated indication of climate-related risk; and reliance on assumptions and future uncertainty (calculations of forward-looking metrics are complex and require many methodological choices and assumptions). Accordingly, undue reliance should not be placed on these forward-looking statements. Furthermore, changing national and international standards, industry and scientific practices, regulatory requirements, and market expectations regarding climate change, which remain under continuous development, are subject to different interpretations. There can be no assurance that these standards, practices, requirements, and expectations will not be interpreted differently than our understanding when defining sustainability-related ambitions and targets or change in a manner that substantially increases the cost or effort for us to achieve such ambitions and targets.
