Cemex closes €750 million bank refinancing

Monterrey, Mexico. April 11, 2024 – Cemex announced today that it has successfully refinanced its Euro denominated sustainability-linked syndicated credit agreement, extending the final maturity to 2029.

The refinanced credit agreement consists of a €450 million 5-year amortizing term loan, and a new €300 million 4-year committed revolving credit facility. This represents a reduction of €50 million in the term loan and an additional source of liquidity in the form of a revolver. The signing of this agreement is an integral part of a comprehensive financing plan designed to increase liquidity and flexibility.

“We have delivered on our commitment of strengthening our financial position, with much better liquidity and with no significant debt maturities in any given year” said Cemex CFO Maher Al-Haffar. “This transaction builds on that commitment by extending our Euro maturities and adding new sources of liquidity.”

The refinanced credit agreement, which is denominated exclusively in Euros, has nearly identical terms and conditions to those in Cemex’s other main bank credit agreement dated October 30, 2023, including guarantor structure, a parallel interest rate margin grid, and financial covenants that provide for a maximum leverage ratio of 3.75x throughout the life of the loan and a minimum interest coverage ratio of 2.75x.

With this transaction, Cemex continues to increase the percentage of its debt aligned to its Future in Action program, which is already above the 2025 target of 50% and brings the company closer to its 2030 target of 85%.

The Joint Bookrunners and Joint Lead Arrangers under the Credit Agreement are Citibank N.A., BNP Paribas, ING Bank N.V., BBVA México S.A., Mizuho Bank Ltd, HSBC Continental Europe, Sumitomo Mitsui Banking Corporation and The Bank of Nova Scotia. The Sustainability Structuring Agent for the Credit Agreement is BBVA México S.A.

The Credit Agreement maintains its guarantor structure, which consists only of Cemex Concretos, S.A. de C.V., Cemex Operaciones México, S.A. de C.V., Cemex Innovation Holding Ltd.

In some cases, 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, expectations (financial or otherwise) and typically can be identified by the use of forward-looking 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” or other similar forward-looking words.

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; climate change, in particular reflected in weather conditions, including but not limited to excessive rain and snow, and disasters such as earthquakes 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; 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;

the impact of pandemics, epidemics, or outbreaks of infectious diseases and the response of governments and other third parties, which could 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 the availability of, and demand for, our products and services; changes in the economy that affect demand for consumer goods, consequently affecting demand for our products and services; the depth and duration of an economic slowdown or recession, instability in the business landscape and lack of availability of credit; declarations of insolvency or bankruptcy, or becoming subject to similar proceedings; and, 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; and the other risks, assumptions, and uncertainties described under “Risk Factors” in our 2022 annual report in Form 20-F filed with the Securities and Exchange Commission of the United States and our 2022 Mexican annual report, filed with the Mexican Banking and Securities Commission, which factors are hereby incorporated by reference. Many factors could cause our expectations, expected results, and/or projections expressed in this press release 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 implementation of technologies, some of which are not yet proven. 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 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 our operations and the development of market conditions in which we operate, or other circumstances or assumptions suggested by such statements may differ materially from those described in, or suggested by, the forward-looking statements contained herein. 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. Readers are urged to read this press release and carefully consider the risks, uncertainties and other factors that affect our business and operations. The information contained in this press release speaks only as of the date of this press release and is subject to change without notice, and except to the extent legally required, we expressly disclaim any obligation or undertaking to update or revise any forward-looking statements in this press release, whether to reflect 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 to the U.S. Securities and Exchange Commission and the Mexican Banking and Securities Commission. There can be no assurance that the transactions described herein will be consummated or as to the ultimate terms of any such transactions.

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 and/or reporting of those activities will meet any present or future expectations or requirements for describing or classifying funding and financing activities 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.
