OPERATION RESILIENCE PAVES ROAD TO A BETTER FUTURE

MONTERREY, MEXICO. SEPTEMBER 10, 2020 – CEMEX, S.A.B. de C.V. (“CEMEX”) (NYSE: CX) announced today the framework of “Operation Resilience,” its medium-term strategy, that incorporates the challenges of the COVID-19 pandemic and lays out a plan to enhance EBITDA growth over the next three years.

During an open dialogue with top management, CEMEX announced that despite significant COVID-19 disruptions, it expects EBITDA for the full year 2020 to grow approximately 4%, on a like to like basis for foreign exchange, over the prior year. This performance results from the decisive management actions as well as better than anticipated market conditions.

With increased visibility and higher EBITDA expectations, CEMEX is comfortable today in rolling out its medium-term strategy.

“Operation Resilience” consists of the following components:

CEMEX also expects to implement the following changes to its Facilities Agreement dated 2017: (i) extend U.S.$1.1 billion of maturities to 2025 and the maturity of the revolver facility to 2023, under similar terms as currently exist; (ii) the inclusion of sustainability metrics that would result in one of the world’s largest sustainability-linked loans when completed; (iii) redenominating U.S.$300 million of previous U.S. Dollar exposure under the terms loan to Mexican Pesos, as well as U.S.$80 million to Euros. As a result, this should translate into no significant debt maturities for CEMEX until mid-2023.

“Operation Resilience lays the foundation for our future. It allows CEMEX to optimize its portfolio for profitable growth while securing its position as a leading vertically integrated heavy building materials company with a focus on four core businesses: cement, ready-mix, aggregates, and urbanization solutions,” said Fernando A. Gonzalez, CEMEX´s CEO. “We will concentrate on developing sustainable urbanization solutions which meet the needs of growing metropolises while we ourselves progress towards achieving our long-term decarbonization goals.”

“Finally, I am confident that the virtuous circle of enhanced EBITDA, increased free cash flow generation and asset divestitures will allow us to achieve our long-sought investment grade capital structure,” added Fernando A. Gonzalez.

Fernando A. Gonzalez, CEMEX´s CEO, Maher Al-Haffar, CEMEX´s CFO, and EVP of Strategic Planning and Business Development, José Antonio González, participated in the open dialogue.

CEMEX has a rich history of improving the well-being of those it serves through innovative building solutions, efficiency advancements, and efforts to promote a sustainable future.
