Exhibit 15.1

Disclosure of Mine Safety and Health Administration (MSHA) Safety Data

Section 1503(a) of the Dodd-Frank Wall Street Reform and Consumer Protection Act (the Act) requires certain disclosures by companies required
to file periodic reports under the Securities Exchange Act of 1934 that operate mines regulated under the Mine Act. CEMEXs U.S. quarry and mining operations are subject to MSHA regulation under the U.S. Federal Mine Safety and Health Act of
1977 (the Mine Act). MSHA inspects the Companys quarries and mines on a regular basis and issues various citations and orders when it believes a violation has occurred under the Mine Act. Whenever MSHA issues a citation or order,
it also generally proposes a civil penalty, or fine, related to the alleged violation. Citations or orders can be contested and appealed, and as part of that process, are often reduced in severity and amount, and are sometimes dismissed or vacated.

In January 2012, the SEC issued final rules and regulations implementing the mine safety disclosure requirements of Section 1503(a) of the
Dodd-Frank Act. Pursuant to those rules and regulations, we have provided the information below for mining operations in the United States only. The Dodd-Frank Act and the implementing rules and regulations thereunder do not apply to mining and
quarry operations outside the U.S.

The information in the table below reflects citations and orders MSHA issued to the Company during the year ended
December 31, 2014. The data was compiled primarily from the data maintained on MSHAs public website, the Mine Data Retrieval System (MDRS), as of March 15, 2015. In evaluating this information, consideration should also
be given to factors such as: (i) the number of citations and orders may vary depending on the size and operation of the mine, (ii) the number of citations issued may vary from inspector to inspector and mine to mine, and
(iii) citations and orders may be contested and appealed, and in that process, may be reduced in severity and amount, and may be dismissed or vacated.
