James Hardie Industries plc Announces

USD $35 Million Accelerated Share Repurchase Transaction

James Hardie Industries plc (“James Hardie”), (ASX:JHX) today announced that it has entered into an accelerated share repurchase agreement with Goldman Sachs Financial Markets Pty Limited (“Goldman Sachs”) to repurchase 2,162,696 James Hardie shares/CUFS with an approximate value of USD $35 million. This transaction is part of James Hardie’s existing USD $100 million share repurchase authorization referred to in James Hardie’s annual results announcement released on 19 May 2016 and the Appendix 3C lodged with ASX on 1 August 2016.

Under the terms of the agreement, Goldman Sachs will deliver to James Hardie 2,162,696 James Hardie shares/CUFS for an initial payment of USD $35 million. The shares/CUFS will be delivered in full by Goldman Sachs to James Hardie two trading days after the trade date. The initial payment of USD $35 million is based on a share/CUFS price of A$21.37 per share/CUFS translated to USD at an AUD/USD exchange rate as of the trade date and is subject to adjustment as detailed further below.

The final price to be paid by James Hardie will be determined based on the average daily volume weighted average price of James Hardie’s shares/CUFS in the ordinary course of ASX trading over an agreed reference period, plus an agreed upon premium, and subject to further adjustments pursuant to the terms of the agreement. The reference period will run for between 8 and 17 trading days commencing on 5 September 2016 and (unless Goldman Sachs elects to exercise its discretion to end the reference period earlier) ending on 27 September 2016. The final price is subject to an agreed cap of A$25.64 per share/CUFS and a floor of A$17.10 per share/CUFS.

Once the final price is determined, there will be a final adjustment and settlement between the parties either in cash or shares, at James Hardie’s election. As such, Goldman Sachs may be required to pay a cash amount or deliver additional shares to James Hardie. Conversely, James Hardie may be required to pay a cash amount or (at its election) deliver shares, to Goldman Sachs. The final settlement payment under the agreement is expected to occur during the second quarter of FY2017.

A further announcement will be made and an Appendix 3F lodged following final settlement of the transaction. This announcement will include confirmation of the final reference period, the final price per share/CUFS paid by James Hardie and the amount of any final cash or share adjustment. In the event that James Hardie is required to make a payment to Goldman Sachs and determines to satisfy that payment obligation through the delivery of James Hardie shares, the number of shares/CUFS so delivered would be calculated by reference to the final price per share/CUFS as described above and constitute fully paid ordinary shares/CUFs ranking equally with all existing

shares/CUFS and be issued without shareholder approval. Based on the capped price per share/CUFS and using the AUD/USD exchange rate as of the trade date, the maximum number of shares to be delivered by James Hardie would be 360,449 (being 16.7% of the shares initially delivered by Goldman Sachs). In that case James Hardie would lodge an Appendix 3B and also confirm the final net number of shares acquired by it through the transaction.
