Posting of LafargeHolcim Unaudited Pro forma Information for 2014 and H1 2015

Regulatory News:

The presentation of the unaudited pro forma information that will be used as a comparison basis moving forward for quarterly and annual earnings is now available on our website at www.lafargeholcim.com, under the section "Investor Relations / Key Financials”.

For the purpose of the proposed merger, the 2014 pro forma information that was included in the Registration Document registered on May 11, 2015 reflected only the effect of the merger Lafarge/Holcim and its direct consequences (notably the divestments to CRH) as known at that time. Now with the merger completed, the pro forma financial information included in today’s release, in addition to the merger and the latest changes in the scope of the divestments achieved in the context of the merger Lafarge/Holcim, also reflects the impact of the reclassification of merger related and restructuring costs, the deconsolidation of the Australian business operated under a joint-venture and the effect of the divestments achieved over the course of 2014 and 2015 initiated or completed by Lafarge.

These figures do not take into consideration any purchase price accounting impact on operating EBITDA which will mainly come from inventory valuation. A breakdown by quarter prepared on a consistent basis of preparation is also provided, together with pro forma information for the first-half of 2015.
