Exhibit 99.6

Address to the 2013 Annual General Meeting

Michael Hammes, Chairman, James Hardie Industries plc

Hello and welcome to James Hardie Industries plc’s 2013 Annual General Meeting (AGM), our fourth AGM to be held in Dublin. It’s great to have you joining us.

In the past year James Hardie has performed well financially and continues to be both operationally and financially strong.

With a steady recovery in the US housing market now entering its third year and the gradual improvement of market conditions in the Asia Pacific region, our focus in fiscal year 2013 was on investing in our businesses to ensure they are well positioned to take advantage of future market opportunities.

Operating earnings for the group were stable relative to fiscal year 2012. In the US, we experienced improving demand for our products and are maintaining our category share and growing our market share against other cladding products. Similarly in Australia, despite the subdued operating environment, we continue to enjoy strong category share, with the Scyon^® product range becoming a larger part of that business.

The investment of A$89 million in our Carole Park, Brisbane Australia manufacturing facility to expand our Australian fibre cement manufacturing capacity will support the continued growth of Scyon^® in Australia and ensure the Australian business is well placed to respond to the increasing preference for composite building materials in residential and commercial construction.

Louis Gries, our Chief Executive Officer (CEO) will address the group financial results, the current operating environment and outlook in greater detail in his presentation.

Now turning our attention to capital management, our continued solid operating performance and confidence in future market opportunities enabled the Board to declare a first half dividend of US5.0 cents and a second half ordinary dividend of US13.0 cents, as well as a special dividend of US24.0 cents per security in May 2013. The resulting full year dividend of US42.0 cents per security in respect of fiscal year 2013 (totalling approximately US$185.5 million) was equal to the prior full year dividend.

The ordinary dividend announced in May 2013 represents an early increase in the company’s dividend payout ratio, which we announced in November 2012, from between 20% and 30% to between 30% and 50% of net operating profit (excluding asbestos adjustments) beginning in fiscal year 2014 onwards. The special dividend represents amounts that were not utilised in the company’s share buyback program which expired in May 2013.

In May this year we also announced a new share buyback program to acquire up to 5% of the company’s issued capital. To the extent that we do not undertake share buybacks, the Board may consider further distributions to shareholders during fiscal year 2014, as part of our capital management strategy.

I would now like to address the issue of board renewal. Donald McGauchie has advised the Board that he will not be standing for a further term if he is re-elected at today’s meeting. For more than ten years, Donald has made a significant contribution to the success of the company, particularly in his capacity as Deputy Chairman during the past six years.

The Board and I have been very fortunate to benefit from his considerable financial and commercial expertise as well as his insight into Australian matters. We are pleased that Donald has agreed to serve a further term so that the Board can consider an appropriate director to take his place.

David Dilger has also advised the Board of his intention to retire at the conclusion of his current term, in August 2013. During the past four years David has served as a member of the Audit and Remuneration Committees as well as a director on some of the company’s Irish subsidiaries. The company has benefited from his substantial executive and board level experience and the Board and I thank him for his valuable contribution.

I would also, at this time, like to acknowledge the contribution to the company of Russell Chenu who announced his intention to retire as James Hardie’s Chief Financial Officer on June 12 this year.

Russell joined James Hardie as Interim CFO in October 2004 and was appointed CFO in February 2005. During his tenure, Russell has been intimately involved in the resolution of several significant legacy issues facing James Hardie, including establishment of the Amended and Restated Final Funding Agreement covering the company’s asbestos compensation arrangements in Australia, the redomicile of James Hardie from the Netherlands to Ireland and the resolution of the 1999 Disputed Amended Assessment with the Australian Taxation Office. Russell also served on James Hardie’s Managing Board between August 2005 and June 2010.

Russell’s contribution to James Hardie has been immense. There is no doubt that the company is in a significantly stronger position than it was when he joined, both from a financial and organisational capability perspective.

In conclusion, under the leadership of CEO, Louis Gries, and the management team, the company has delivered another set of sound operating results, and the company is strongly positioned to leverage its increased capabilities for the medium and longer term.
