Cemex reports record third quarter EBITDA

with 32% growth and material margin expansion

Monterrey, Mexico. October 26, 2023 – Cemex reported today another quarter of exceptional results, with a 9% growth in Sales and 32% increase in EBITDA, and EBITDA Margin expansion of 3.5pp to 19.9%. For the first time since the launch of Cemex’s pricing strategy in 2021, designed to regain profitability after a surge in input cost inflation, quarterly EBITDA margin exceeded our goal of recovering 2021 margins. Free cash flow after maintenance capex grew significantly, reflecting EBITDA growth and lower working capital spending. Leverage ratio stood at 2.16x, marking the third consecutive quarter of declining leverage, accelerating the path to an investment grade rating.

Results were bolstered by Cemex’s strong pricing across all markets, decelerating input cost inflation, contributions from Cemex’s growth investment strategy, and Urbanization Solutions business. In the third quarter of 2023, growth investments contributed 11% of incremental EBITDA and 10% of total EBITDA.

“2023 is proving to be an exceptional year for our company, and I am especially encouraged by our recovery of EBITDA margins to 2021 levels, a key strategic priority,” says Fernando A. González, CEO of Cemex. “The success of our pricing strategy, contribution of growth investments and our fast-growing Urbanization Solutions business, as well as decelerating cost inflation, are contributing to profitability in a very meaningful way. Importantly, we are making significant progress on our decarbonization roadmap, reducing Scope 1 and Scope 2 carbon emissions by 12% and 11%, respectively, since 2020. Prior to the introduction of our Future in Action program in 2020, a reduction of this magnitude would have taken almost 15 years”.

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.

Operating results

Mexico

In millions of U.S. dollars, except percentages.

Our Mexican operations delivered strong results, with a 21% growth in Sales supported by a double-digit increase in volumes and prices across all products. Operating EBITDA also increased by 31%, marking the fourth consecutive quarter of growth. Operating EBITDA margin expanded 2.4pp year-over-year on the back of strong pricing and volumes, coupled with decelerating costs.

The Urbanization Solutions business contributed to approximately 12% of Mexico’s total incremental Operating EBITDA growth in the quarter.

Cement volumes rose double-digit, the second consecutive quarter of growth, supported by an increase in bagged cement volumes for the first time since second quarter of 2021, while bulk cement continued its double-digit growth trajectory driven by the formal sector. Ready-mix and aggregates volumes also benefited from strength in formal construction with double-digit volume growth.

Cement prices were flat sequentially, while ready-mix and aggregates increased by 2% and 5%, respectively.

During the quarter, our 1.5-million-ton capacity expansion in Tepeaca came online, allowing us to serve the expected medium-term demand of the country at a lower cost per ton than existing capacity.

United States

In millions of U.S. dollars, except percentages.

The United States had another strong quarter with Operating EBITDA growing by 36%, driven by pricing strategy and decelerating costs. Operating EBITDA margin expanded 4.4pp year-over-year due to prices, decelerating costs, and lower imports, however, it declined sequentially mainly due to higher maintenance and lower volumes.

Cement and ready-mix prices rose double digits, while aggregates increased high single-digit. On a sequential basis, cement and ready-mix prices rose low single-digit, reflecting the success of our second half price increases implemented in most of our states.

Operating results

Cement and ready-mix volumes declined primarily due to continued weakness in California along with the winding down of several large industrial projects. Aggregates volumes grew in the quarter, benefiting from recent acquisitions in Florida and Canada.

Commercial and residential activity slowed during the quarter, while infrastructure activity continued to grow. In response to the demand environment, we reduced cement imports to support margins.

Europe, Middle East, Africa and Asia

In millions of U.S. dollars, except percentages.

EMEA delivered solid results despite a challenging demand environment, with Operating EBITDA continuing to grow, while margin expanded to the highest level since the onset of the pandemic.

In Europe, Operating EBITDA rose 17%, while margin increased to a record high of 17.3%, a 2.6pp increase. Despite lower volumes, pricing remained resilient with cement prices up 21%, commensurate with a still elevated inflationary environment, while prices were flat sequentially. Ready-mix and aggregate prices also showed significant growth but declined slightly sequentially due to geographic mix.

In Asia, Middle East and Africa, Operating EBITDA increased low single-digits in the quarter while margin contracted by 1.2pp, primarily due to the competitive environment in the Philippines.

Operating results

South, Central America and the Caribbean

In millions of U.S. dollars, except percentages.

Net sales and Operating EBITDA in the South, Central America and Caribbean region rose 11% and 18%, respectively, driven primarily by prices and decelerating energy costs. Margin improved 1pp with a slight decline in sequential margin, which is largely explained by higher maintenance in the quarter.

Cement prices for the region rose high single-digit. Despite continued pressure in bagged cement in the region, volumes grew for the first time in two years, driven largely by positive performance in Panama, the Dominican Republic, and Jamaica. Demand has been supported by formal construction related to infrastructure projects, such as the Bogotá Metro in Colombia, the 4th Bridge over the Canal in Panama and tourism related projects in the Dominican Republic and Jamaica.

Operating results

Operating EBITDA and free cash flow

Higher Operating EBITDA and a lower investment in working capital, partially offset by higher taxes, resulted in free cash flow after maintenance capex of almost US$700 million year-to-date, US$535 million higher than the same period last year.

The increase in cash taxes is a consequence of stronger results, as well as the tax effect of foreign exchange on our U.S. dollar denominated debt.

During the quarter, the main uses of cash below the Free cash flow line relate to the payment of coupons of our subordinated notes with no fixed maturity, as well as from our derivative instruments.

Information on debt

In millions of U.S. dollars, except percentages and ratios.

On October 30^th 2023, we expect to close the refinancing of our syndicated bank facility, which would now consist of a US$1 billion term loan and US$2 billion committed revolving credit facility. Additionally, in early October we issued $6 billion of peso-denominated sustainability-linked long-term notes (certificados bursátiles de largo plazo) in Mexico - the equivalent of approximately US$335 million. The information on debt above does not reflect these transactions executed during October 2023.
