The closing of the offering is expected to occur on November 19, 2019, subject to satisfaction of customary closing conditions.

CEMEX intends to use the net proceeds from the offering of the Notes for general corporate purposes, including to repay other indebtedness, all in accordance with CEMEX’s facilities agreement, dated as of July 19, 2017 (as amended and restated on April 2, 2019 and November 4, 2019, the “Facilities Agreement”), entered into with several financial institutions.

The Notes will share in the collateral pledged for the benefit of the lenders under the Facilities Agreement and other secured obligations having the benefit of such collateral, and will be guaranteed by CEMEX México, S.A. de C.V., CEMEX Concretos, S.A. de C.V., Empresas Tolteca de México, S.A. de C.V., New Sunward Holding B.V., CEMEX España, S.A., Cemex Asia B.V., CEMEX Corp., CEMEX Finance LLC, Cemex Africa & Middle East Investments B.V., CEMEX France Gestion (S.A.S.), Cemex Research Group AG and CEMEX UK.

This release is neither an offer to purchase nor a solicitation of an offer to sell or buy any securities of CEMEX in any transaction.

The Notes and the guarantees thereof have not been and will not be registered under the U.S. Securities Act of 1933, as amended (the “Securities Act”), or any state securities laws, and they may not be offered or sold in the United States absent registration or an applicable exemption from the registration requirements of the Securities Act. The Notes are being offered only to qualified institutional buyers pursuant to Rule 144A and outside the United States pursuant to Regulation S, both as promulgated under the Securities Act.

THE NOTES HAVE NOT BEEN AND WILL NOT BE REGISTERED WITH THE MEXICAN NATIONAL SECURITIES REGISTRY (REGISTRO NACIONAL DE VALORES, OR “RNV”), MAINTAINED BY THE MEXICAN NATIONAL BANKING AND SECURITIES COMMISSION (COMISIÓN NACIONAL BANCARIA Y DE VALORES, OR “CNBV”), AND THEREFORE MAY NOT BE OFFERED OR SOLD PUBLICLY IN MEXICO, EXCEPT THAT THE NOTES MAY BE OFFERED AND SOLD IN MEXICO TO INVESTORS THAT QUALIFY AS INSTITUTIONAL AND QUALIFIED INVESTORS SOLELY PURSUANT TO THE PRIVATE PLACEMENT EXEMPTION SET FORTH IN

ARTICLE 8 OF THE MEXICAN SECURITIES MARKET LAW (LEY DEL MERCADO DE VALORES, OR THE “MEXICAN SECURITIES MARKET LAW”). UPON THE ISSUANCE OF THE NOTES, WE WILL NOTIFY THE CNBV OF THE ISSUANCE OF THE NOTES, INCLUDING THE PRINCIPAL TERMS AND CONDITIONS OF THE NOTES AND THE OFFERING OF THE NOTES OUTSIDE MEXICO. SUCH NOTICE WILL BE SUBMITTED TO THE CNBV TO COMPLY WITH ARTICLE 7, SECOND PARAGRAPH OF THE MEXICAN SECURITIES MARKET LAW AND REGULATIONS THEREUNDER, AND FOR STATISTICAL AND INFORMATION PURPOSES ONLY, AND THE DELIVERY TO AND THE RECEIPT BY THE CNBV OF SUCH NOTICE, DOES NOT CONSTITUTE OR IMPLY ANY CERTIFICATION AS TO THE INVESTMENT QUALITY OF THE NOTES OR OF OUR SOLVENCY, LIQUIDITY OR CREDIT QUALITY OR THE ACCURACY OR COMPLETENESS OF THE INFORMATION SET FORTH IN THE DOCUMENTS OF THIS OFFERING. THE INFORMATION CONTAINED IN THE DOCUMENTS USED FOR THIS OFFERING OF THE NOTES IS THE EXCLUSIVE RESPONSIBILITY OF CEMEX AND HAS NOT BEEN REVIEWED OR AUTHORIZED BY THE CNBV.

This communication does not constitute an offer to sell or a solicitation of an offer to buy or an advertisement in respect of Notes in any province or territory of Canada other than the provinces of Alberta, British Columbia, Nova Scotia, Ontario, Québec and Saskatchewan, and in those permitted provinces only to investors that are “accredited investors” as defined in National Instrument 45-106 Prospectus Exemptions and “permitted clients” as defined in National Instrument 31-103 Registration Requirements, Exemptions and Ongoing Registrant Obligations.

The Notes are not intended to be offered, sold or otherwise made available to and should not be offered, sold or otherwise made available to any retail investor in the European Economic Area (“EEA”). For these purposes, (a) a retail investor means a person who is one (or more) of: (i) a retail client as defined in point (11) of Article 4(1) of Directive 2014/65/EU (as amended, “MiFID II”); or (ii) a customer within the meaning of Directive (EU) 2016/97, where that customer would not qualify as a professional client as defined in point (10) of Article 4(1) of MiFID II; or (iii) not a qualified investor as defined in the Prospectus Regulation, and (b) the expression “offer” includes the communication in any form and by any means of sufficient information on the terms of the offer and the Notes to be offered so as to enable an investor to decide to purchase or subscribe for the Notes. Consequently, no key information document required by Regulation (EU) No 1286/2014 (as amended, the “PRIIPs Regulation”) for offering or selling the Notes or otherwise making them available to retail investors in the EEA has been prepared and therefore offering or selling the Notes or otherwise making them available to any retail investor in the EEA may be unlawful under the PRIIPs Regulation.

MiFID II product governance/professional investors and ECPs only target market—Solely for the purposes of each manufacturer’s product approval process, the target market assessment in respect of the Notes has led to the conclusion that: (i) the target market for the Notes is eligible counterparties and professional clients only, each as defined in MiFID II; and (ii) all channels for distribution of the Notes to eligible counterparties and professional clients are appropriate. Any person subsequently offering, selling or recommending the Notes (a “distributor”) should take into consideration the manufacturers’ target market assessment; however, a distributor subject to MiFID II is responsible for undertaking its own target market assessment in respect of the Notes (by either adopting or refining the manufacturers’ target market assessment) and determining appropriate distribution channels.

Singapore SFA Product Classification — In connection with Section 309B of the SFA and the CMP Regulations 2018, unless otherwise specified before an offer of Notes, the Issuer has determined, and hereby notifies all relevant persons (as defined in Section 309A(1) of the SFA), that the Notes are “prescribed capital markets products” (as defined in the CMP Regulations 2018) and Excluded Investment Products (as defined in MAS Notice SFA 04-N12: Notice on the Sale of Investment Products and MAS Notice FAA-N16: Notice on Recommendations on Investment Products).

Promotion of the Notes in the United Kingdom is restricted by the Financial Services and Markets Act 2000, and accordingly, the Notes are not being promoted to the general public in the United Kingdom.

This communication is for distribution only to, and is only directed at, (i) persons who are outside the United Kingdom or (ii) investment professionals falling within Article 19(5) of the Financial Services and Markets Act 2000 (Financial Promotion) Order 2005 (the “Order”) or (iii) high net worth companies and other persons to whom it may lawfully be communicated, falling within Article 49(2)(a) to (d) of the Order (each such person being referred to as “relevant persons”). The Notes will only be available to, and any invitation, offer or agreement to subscribe, purchase or otherwise acquire such Notes will be engaged in only with, relevant persons. This communication is directed only at relevant persons and must not be acted on or relied on by anyone who is not a relevant person.
