Exhibit 1

CEMEX, S.A.B. de C.V. (“CEMEX”) (NYSE: CX) announced today that it has repaid in full all outstanding indebtedness under CEMEX’s facilities agreement, dated as of July 19, 2017 (as amended and/or restated from time to time, the “2017 Facilities Agreement”), which amounted to approximately U.S.$1.90 billion in different currencies. Following this repayment in full, the 2017 Facilities Agreement is no longer in effect.

The funds used to repay the 2017 Facilities Agreement were sourced from a new unsecured credit agreement, dated October 29, 2021 (the “2021 Credit Agreement”), that was closed with 21 financial institutions participating as lenders.

The main terms and conditions of the 2021 Credit Agreement are summarized as follows:

Concurrently with funding under the 2021 Credit Agreement and in accordance with the indentures governing the Notes, CEMEX entered into supplemental indentures to add CEMEX Operaciones México, S.A. de C.V. and Cemex Innovation Holding Ltd. as new guarantors to CEMEX’s 2.750% Euro Denominated Notes due 2024, 3.125% Euro Denominated Notes due 2026, 5.450% U.S. Dollar Denominated Notes due 2029, 7.375% U.S. Dollar Denominated Notes due 2027, 5.200% U.S. Dollar Denominated Notes due 2030 and 3.875% U.S. Dollar Denominated Notes due 2031 (collectively, the “Notes”). CEMEX Corp. and CEMEX Concretos, S.A. de C.V. were already guarantors of the Notes.

Also, concurrently with funding under the 2021 Credit Agreement and the full repayment of the 2017 Facilities Agreement, the provisions contained in the indentures governing the Notes that provide that any guarantor of the Notes (the “Note Guarantors”) shall be released of its guarantee obligations upon a refinancing of the 2017 Facilities Agreement with debt not guaranteed by the Note Guarantors, have been triggered. As a result, both the 2021 Credit Agreement and the Notes are guaranteed exclusively by the Refinancing Guarantors (CEMEX Corp., CEMEX Concretos, S.A. de C.V., CEMEX Operaciones México, S.A. de C.V. and Cemex Innovation Holding Ltd.).

The Note Guarantors that are no longer guaranteeing the Notes are CEMEX España, S.A., CEMEX Asia B.V., CEMEX Finance LLC, CEMEX Africa & Middle East Investments B.V., CEMEX France Gestion (S.A.S.), CEMEX Research Group AG and CEMEX UK.

CEMEX CLOSES UNSECURED BANK AGREEMENT WITH INVESTMENT

GRADE TERMS AND CONDITIONS FOR U.S.$3.25 BILLION

MONTERREY, MEXICO. NOVEMBER 8, 2020 – CEMEX, S.A.B. de C.V. (“CEMEX”) (NYSE: CX) announced today that it has successfully closed a new $3.25 billion syndicated credit agreement (the “Credit Agreement”) and used the proceeds to fully repay its previous facilities agreement.

The new Credit Agreement consists of a $1.5 billion 5-year amortizing Term Loans and a $1.75 billion 5-year committed Revolving Credit Facility. The committed facility is roughly $600 million higher than the previous facilities agreement, resulting in a stronger liquidity position which is favorable from a company risk and credit rating perspective.

The Credit Agreement has financial covenants consistent with an investment grade capital structure, with a maximum leverage ratio of 3.75x throughout the life of the loan, and a minimum interest coverage ratio of 2.75x.

The Credit Agreement is denominated exclusively in US Dollars and includes an interest rate margin grid that is about 25 basis points lower on average than that of the previous facilities agreement. Additionally, half of the Term Loans have been swapped into Euros using derivative instruments.

Furthermore, the new Credit Agreement is the first debt to be issued under CEMEX’s recently published Sustainability-linked Financing Framework (the “Framework”), which is aligned to the company’s Future in Action strategy and its ultimate vision of a carbon-neutral economy. The annual performance in respect to the three metrics referenced in the Framework may result in a total adjustment of the interest rate margin of plus or minus 5 basis points, in line with other sustainability-linked loans from investment grade rated borrowers.

“This new Credit Agreement represents a major milestone in our path to investment grade as it is our first major syndicated unsecured bank agreement since 2009. It showcases CEMEX’s continued access to diversified funding sources while further aligning our financing strategy to our leadership in addressing climate change,” said CEMEX CEO Fernando A. Gonzalez. “We are starting a new chapter for the company where we shift our strategic balance a bit more towards growth and the advancement of our Climate Action goals.”

The Joint Bookrunners and Joint Lead Arrangers under the 2021 Credit Agreement are BofA Securities Inc., BNP Paribas, Citigroup Global Markets Inc. and JPMorgan Chase Bank, N.A. The Sustainability Structuring Agent for the 2021 Credit Agreement is ING Capital LLC.

Additionally, the Credit Agreement has a simpler guarantor structure to that of the previous facilities agreement. This new guarantor structure has been replicated in all of CEMEX’s senior notes and consists only of CEMEX Concretos, S.A. de C.V., CEMEX Operaciones México, S.A. de C.V., Cemex Innovation Holding Ltd. and CEMEX Corp.
