Dear Sir/Madam,

Changes to the Format of Results Materials Released by James Hardie Industries plc

James Hardie wishes to advise that commencing with the release of the company’s results for the first quarter of fiscal year 2015, the company has revised the format and layout of its results materials, specifically the media release and management’s analysis of results.

The management’s analysis of results will now start with an overall analysis of the group’s results, followed by an analysis of our operating results by segment (USA & Europe Fibre Cement followed by Asia Pacific Fibre Cement) together with any supplementary financial or operating information.

A pro-forma of the media release and management’s analysis of the results is attached.

The intention behind making the changes was to improve the overall flow of our documents and to provide a clearer analysis of results to the reader, by addressing our results on a consolidated, then segment basis. It is hoped that by presenting our results in this way, the market is more readily able to follow and understand the discussion of our financial performance.

James Hardie will release its Q1FY15 results on Friday 15 August 2014. Further information on how to access the webcast of the results presentation and materials is available on our Investor Relations website at: http://www.ir.jameshardie.com.au/jh/results_briefings.jsp

Please contact our investor relations team on +61 2 8845 3360 if you have any questions.

Yours faithfully,

/s/ Sean O’Sullivan
