Many factors could cause our expectations, expected results, and/or projections expressed in this presentation and in the events referenced herein 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 also 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, performance and/or achievements may vary materially from historical results, performance, and/or achievements and/or results; performance and/or achievements expressly or implicitly anticipated by the forward-looking statements; or otherwise, could have an impact on us. Forward-looking statements should not be considered guarantees of future performance, and past results or developments are not indicative of results or developments in subsequent periods. Actual results, performance and/or achievements of our operations and the development of market conditions in which we operate, or other circumstances that may materialize, may differ materially from those described in, or suggested by, the forward-looking statements contained in this presentation, and events referenced therein. Any or all of our 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 disclosed 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 CNBV and the BMV. Market data used in this presentation and events referenced herein not attributed to a specific source are our estimates 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 our internal records. This presentation includes certain non-International Financial Reporting Standards (“IFRS”) financial measures that differ from financial information presented by us in accordance with IFRS in our financial statements and reports containing financial information. The aforementioned non-IFRS financial measures include “Operating EBITDA” or “EBITDA” (operating earnings before other expenses, net plus depreciation and amortization), “Operating EBITDA Margin” or “EBITDA Margin” (Operating EBITDA for the period divided by revenues reported for the same period), “Operating EBIT” or “EBIT” (operating earnings before other expenses, net), “Free Cash Flow from Operations” (Operating EBITDA minus net interest paid, maintenance capital expenditures, maintenance lease payments, fixed asset sales, change in working capital, net taxes paid, and other cash expenditures), and “Adjusted Free Cash Flow from Operations Conversion Rate” (measures how much of the company’s operating earnings turn into actual cash). 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. We believe there is no close IFRS financial measure to compare to Operating EBITDA Margin. The closest IFRS financial measure to Operating EBIT is “Operating earnings before other expenses, net.” We believe there is no close IFRS financial measure to compare to Free Cash Flow from Operations. We believe there is no close IFRS financial measure to compare to Adjusted Free Cash Flow from Operations Conversion Rate. 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, Operating EBITDA Margin, Operating EBIT and Free Cash Flow from Operations 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 our management to review operating performance and profitability, for decision-making purposes and to allocate resources. Moreover, our Operating EBITDA is a measure used by our creditors to review our ability to internally fund capital expenditures, service or incur debt and comply with financial covenants under our financing agreements. Furthermore, our 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. The financial measures presented in this 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 production, distribution, marketing and sale of cement, ready-mix concrete, clinker, aggregates, and Urbanization Solutions. We generated some of this data internally, and some was obtained from independent industry publications and reports that we believe to be reliable sources. We have not independently verified this data nor sought the consent of any organizations to refer to their reports in this presentation. We act in strict compliance with antitrust laws and as such, among other measures, maintain an independent pricing policy that has been independently developed, and its core element is to price our products and services based upon their quality and characteristics as well as their value to our customers. We do not accept any communications or agreements of any type with competitors regarding the determination of our prices for our products and services. Unless the context indicates otherwise, all references to pricing initiatives, price increases or decreases, refer to our prices for our products. The information, statements, and opinions contained in this presentation are for informational purposes only and 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. You should not construe any such information or other material as legal, tax, investment, financial, or other advice. We are not responsible for any third-party information referenced in this presentation. 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 this 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. The disclosure of information on sustainability-related matters is not yet subject to the same recognized or accepted reporting or accounting principles and rules as traditional financial information. Consequently, there are no commonly accepted reporting practices for us to follow, and ESG metrics among organizations in our industry may not be comparable. 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 this 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 such activities, products, assets or projects and/or reporting of those activities, products, assets or projects will meet any present or future expectations or requirements for describing or classifying such activities, products, assets or projects 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 this 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 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 current “Future in Action” climate action and nature program, as well as 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 and regulations, 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; excessive costs and expenses related to acquire and/or develop technology for mitigation; the roll-out of low carbon infrastructure; the availability and adoption of renewable energy 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; 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.
