The information to be disclosed in the events referenced in this report contains forward-looking statements within the meaning of the U.S. federal securities laws and information that are necessarily subject to risks, uncertainties, and assumptions, including but not limited to statements related to CEMEX’s plans, objectives, expectations (financial or otherwise), and typically can be identified by the use of words such as “will,” “may,” “assume,” “might,” “should,” “could,” “continue,” “would,” “can,” “consider,” “anticipate,” “estimate,” “expect,” “envision,” “plan,” “believe,” “foresee,” “predict,” “potential,” “target,” “strategy,” “intend,” “aimed,” and similar terms. 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 materially from historical results or results anticipated by forward-looking statements due to various factors. Factors that could cause actual results to differ materially from historical results or those contemplated above include, among others, risks and uncertainties discussed in CEMEX’s most recent annual report and detailed from time to time in CEMEX’s other filings with the Securities and Exchange Commission, which factors are incorporated herein by reference, including, but not limited to: the impact of pandemics, epidemics or outbreaks of infectious diseases and the response of governments and other third parties, including with respect to COVID-19, which have affected and may continue to adversely affect, among other matters, the ability of our operating facilities to operate at full or any capacity, supply chains, international operations, availability of liquidity, investor confidence and consumer spending, as well as availability of, and demand for, our products and services; the cyclical activity of the construction sector; our exposure to other sectors that impact our and our client’s business, such as, but not limited to, the energy sector; availability of raw materials and related fluctuating prices; volatility in pension plan asset values and liabilities, which may require cash contributions to the pension plans; the impact of environmental cleanup costs and other liabilities relating to existing and/or divested businesses; our ability to secure and permit aggregates reserves in strategically located areas; the timing and amount of federal, state and local funding for infrastructure; changes in the level of spending for private residential and private nonresidential construction; changes in our effective tax rate; competition in the markets in which we offer our products and services; general political, social, health, economic and business conditions in the markets in which we operate or that affect our operations and any significant economic, health, political or social developments in those markets, as well as any inherent risks to international operations; the regulatory environment, including environmental, energy, tax, antitrust, labor and acquisition-related rules and regulations; our ability to satisfy our obligations under our material debt agreements, the indentures that govern our outstanding notes and other debt instruments and financial obligations; the availability of short-term credit lines or working capital facilities, which can assist us in connection with market cycles; the impact of our below investment grade debt rating on our cost of capital and on the cost of the products and services we purchase; loss of reputation of our brands; our ability to consummate asset sales, fully integrate newly acquired businesses, achieve cost-savings from our cost-reduction initiatives, implement our pricing initiatives for our products and generally meet our “Operation Resilience” strategy goals; 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 cyber-attacks; changes in the economy that affect demand for consumer goods, consequently affecting demand for our products and services; weather conditions, including, but not limited to, excessive rain and snow, and disasters such as earthquakes and floods; trade barriers, including tariffs or import taxes and changes in existing trade policies or changes to, or withdrawals from, free trade agreements, including the United States-Mexico-Canada Agreement (“USMCA”), which was signed on

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. Any or all of CEMEX’s forward-looking statements may turn out to be inaccurate and the factors identified above are not exhaustive. Accordingly, you should not place undue reliance on forward-looking statements, which speak only as of the dates on which they are made. These factors may be revised or supplemented, but CEMEX is not under, and expressly disclaims, any obligation to update or correct the information contained in this report or any forward-looking statement that it may make from time to time, whether as a result of new information, future events or otherwise.
