CEMEX REPORTS 1% TOP-LINE GROWTH AND A 92% INCREASE IN NET INCOME DURING THE FIRST QUARTER OF 2019

MONTERREY, MEXICO, APRIL 25, 2019– CEMEX, S.A.B. de C.V. (“CEMEX”) (NYSE: CX), announced today that, on a like-to-like basis for the ongoing operations and adjusting for foreign exchange fluctuations, consolidated net sales increased by 1%, reaching US$3.2 billion during the first quarter of 2019 versus the comparable period in 2018. Operating EBITDA decreased by 3% on a like-to-like basis during the first quarter of 2019 to US$562 million on a year-over-year basis.

CEMEX’s Consolidated First-Quarter 2019 Financial and Operational Highlights

Fernando A. Gonzalez, Chief Executive Officer of CEMEX, said: “We are pleased with the 1% top-line growth we achieved during the first quarter, despite important volume declines in our two most important markets: Mexico and the US. During the quarter, we enjoyed improved pricing performance in all our regions with favorable volume dynamics in Europe. In the US, ready-mix and aggregates volumes also grew despite adverse weather in part of our footprint. In addition, operating cash flow performance was bolstered by the ongoing successful implementation of our A Stronger CEMEX Initiatives.

Our EBITDA generation during the quarter was impacted by lower volumes in our other regions, higher energy costs and purchased cement as well as increased raw-material costs in our ready-mix business. We expect EBITDA to improve in the following quarters and end 2019 at a higher level than in 2018.”

Consolidated Corporate Results

During the first quarter of 2019, controlling interest net income was US$39 million, versus US$20 million in the same period last year.

Net debt plus perpetual notes increased by US$94 million during the quarter.

The transition phase of the new government resulted in lower infrastructure investment, intensified by the termination of important projects last year, as well as reduced housing activity in anticipation of the announcement and implementation of new housing policies and regulations. The industrial-and-commercial sector drove cement consumption during the quarter, stimulated by tourism activity in the Pacific and Southeast regions. The formal residential sector underwent a significant drop in consumption reflecting a slower-than-expected start of new housing programs. The self-construction sector also experienced a decline in consumption during the quarter.

In the Philippines, our domestic gray cement volumes decreased by 1% during the quarter on a year-over-year basis with activity still recovering at the start of the year, after the landslide that took place last September. Cement volumes in the quarter were supported by the residential and infrastructure sectors. In Egypt, our domestic gray cement volumes declined by 31% during the first quarter on a year-over-year basis. The quarterly volume decrease was mainly due to weaker market demand and changes in supply-demand dynamics as temporarily stopped and new capacity came online. In Israel, during the first quarter, our ready-mix volumes declined by 3%, while our aggregates volumes decreased by 4%, year-over-year. This drop in volumes is mainly the result of adverse weather conditions during the quarter.
