CEMEX LATAM HOLDINGS REPORTS

FIRST QUARTER 2018 RESULTS

• Consolidated prices of our three core products during the quarter increased on a sequential basis both in local-currency and in U.S. dollar terms. Our cement prices increased on a sequential basis in Colombia, Costa Rica and Brazil.

• Our net income reached US$30 M during the quarter compared to US$35 M in the same quarter last year.

BOGOTA, COLOMBIA. APRIL 26, 2018 – CEMEX Latam Holdings, S.A. (“CLH”) (BVC: CLH), announced today that consolidated net sales reached US$301 million during the first quarter of 2018, decreasing by 8% compared to those of the same period in 2017. Operating EBITDA declined by 29% during the first quarter, compared to that of the same period in 2017.

During the first quarter of 2018, our consolidated domestic gray cement, ready-mix and aggregates volumes decreased by 9%, 11% and 5%, respectively, compared to those of the first quarter of 2017. Our consolidated prices for domestic gray cement, ready-mix and aggregates increased in local-currency by 4%, 3% and 1%, respectively, during the quarter on a sequential basis.

Jaime Muguiro, CEO of CLH, said, “We had significant headwinds during the quarter: weak industry volumes in Colombia and Panama, as well as a difficult comparison base for prices in Colombia.

With regards to pricing performance, we are encouraged with the upward trend of our cement prices in Colombia during the last two quarters, as price recovery is critical to improving our margins which declined materially in 2017.

Our Free Cash Flow during the quarter was negative 31 million dollars mainly due to the payment of the fine imposed by the Superintendence of Industry and Commerce in Colombia”

CLH’s Financial and Operational Highlights

• In Colombia, cement prices continued their upward trajectory shown in the fourth quarter of 2017, and increased by 3% during the first quarter of 2018 on a sequential basis, in local currency.

• Cement, ready-mix and aggregates volumes in Costa Rica increased by 5%, 11% and 31%, respectively, during the quarter on a year over year basis. Our cement and concrete prices in local-currency terms increased by 2% sequentially in this period.

• In our Rest of CLH region during the first quarter, our ready-mix and aggregates volumes increased by 20% and 36%, respectively, compared to those of the same period in 2017.

• During the quarter our total debt was reduced by US$25 million to US$935 million, compared to that of the same quarter of 2017.

• Free cash flow decreased to negative US$31 million during the quarter. Lower financial expense, capex and taxes, were more than offset by lower EBITDA, a higher negative working capital variation, as well as the fine imposed by the Superintendent of Industry and Commerce in Colombia.

Jaime Muguiro added, “We expect a better second half of the year driven by improved prices in Colombia, increased demand in Panama, higher volumes and prices in Costa Rica, as well as the start of highway projects in Nicaragua. On the other hand, the construction-workers-union strike in Panama and the protests in Nicaragua, could impact our second quarter results.

Going forward this year, we expect to generate positive free cash flow due to lower taxes and capex, and the recovery of the working-capital invested so far. We are committed to continue reducing our debt and leverage”

Consolidated Corporate Results

During the first quarter of the year, controlling interest net income was US$30 million compared to US$35 million during the first quarter of 2017.

Net debt during the first quarter of 2018 was US$903 million.

Consolidated net sales during the first quarter of 2018 declined by 8% compared to those of the first quarter 2017. The decline in net sales on a year over year basis was mainly due to lower volumes in Colombia and Panama, as well as lower cement prices in Colombia. Cost of sales as a percentage of net sales during the quarter increased by 4.3pp from 54.2% to 58.5% on a year-over-year basis. Operating expenses as a percentage of net sales during the first quarter increased by 2.4pp from 24.0% to 26.4% compared to that of the same period in 2017. Operating EBITDA during the first quarter of 2018 declined by 29% compared to that of the first quarter of 2017. The decline is mainly due to weak volumes in Colombia and Panama, a difficult comparison base for prices in Colombia, as well as a negative product-mix effect and a major kiln maintenance in Panama. Operating EBITDA margin during the first quarter of 2018 declined by 6.3pp, compared to that of the first quarter of 2017. Controlling interest net income during the first quarter of 2018 reached US$30 million compared to US$35 million in the same period of 2017. Total debt at the end of the quarter reached US$935 million.

Our focus on pricing strategy, led to a slight underperformance of our cement volumes versus the industry during the quarter on a year over year basis. Our cement prices continued their upward trajectory shown in the fourth quarter of 2017 and increased by 3% this quarter in local currency on a sequential basis. Our cement prices as of March this year, compared to those of June 2017, were 7% higher in local currency terms and 17% higher in U.S. dollar terms. Despite the expected improvement in GDP growth this year, the upward trajectory of oil prices, as well as historic low interest rates, construction activity continued declining during the first quarter of 2018. Our estimations indicate that during the first quarter national cement consumption including imports declined by 8 percent, or by 5 percent when adjusted for fewer working days.

Our estimations indicate that industry volumes during the quarter in Panama declined by 9%, or 7% when adjusted for fewer working days. Weak demand was anticipated during the first half of the year because of high home inventories in Panama City, as well as delays in the approval and execution of infrastructure projects. Our cement volumes declined by 18% in this period due to a lower cement market position, as we maintained our prices in a weak demand environment. We expect to recover our market position in coming months.

Regarding our prices, both cement and ready-mix prices increased by 2% on a sequential basis during the quarter. The improvement in cement reflects our price increase implemented during the quarter, while the ready-mix price increase reflects higher sales of our value-added products, as well as the positive effect of services and surcharges.

Regarding our cement volumes, we observed delays in already contracted highways projects in Nicaragua, partially offset by higher volumes in Brazil. In the ready-mix business, volumes increased mainly due to improved service from our operation in Guatemala. With regards to Guatemala we partially compensated lost volumes from two mining projects that shutdown during the second quarter of 2017, with increased volumes to retailers and to our ready-mix operations. In our cement business, we are directly reaching more small retailers, while in ready-mix we are strengthening the service and coverage capabilities of our operations.

9 Despite low-income housing sales reaching historic highs year-to-date February,housing starts decreased by about 12% in this period In the middle-and high-income segment, housing sales and starts continued declining year-to-date February, however, housing starts in this segment increased double-digits in this period compared to those of November-December 2017 Cement dispatches for housing projects remained weak during the quarter ||Colombia –Residential Sector We expect industry cement demand for this sector to accelerate during 2H18 and increase by 1% this year, supported by lower interest rates, improved subsidies execution, as well as by the improvement in the intention-to-buy-a-home-indicator, which is now back up to the 5-year avg.

10 Low levels of public investment during 1Q18 due to the Ley de Garantíaswhich ends its enforcement in coming months after the elections Volumes to this sector supported by two relevant projects in Bogotá:the PTAR Salitrewater plant and the CETIC Hospital 4G projects advancing slowly, estimated total ready-mix consumption to reach 430,000 m3 in 2018, of which we expect to supply 150,000 m3 ||Colombia –Infrastructure Sector We expect industry cement demand to this sector to remain flat during 2018
