James Hardie Industries plc (“James Hardie” or the “Company”), a leader in high-performance, low-maintenance building product solutions, successfully completed its previously announced acquisition of The AZEK® Company (“AZEK”) in a cash-and-stock transaction for $26.45 in cash and 1.0340 ordinary shares of James Hardie for each share of AZEK common stock held for a total of $54.18 per share, based on the closing stock price of AU$40.77 per share based on James Hardie’s CHESS Depositary Interest (CDI) listing on the Australian Securities Exchange (ASX) and an exchange rate of 0.6579. This represents an implied value of $8.4 billion, including the value of share-based awards and the repayment of AZEK’s outstanding debt.

“I want to thank our James Hardie teammates for their focus and dedication to our customers, and to the AZEK team, I am pleased to formally welcome you to James Hardie,” said Aaron Erter, Chief Executive Officer, James Hardie. “Together, we are a stronger team and have never been better positioned to serve our customers and create value for all our stakeholders. As a combined organization, our purpose of Building a Better Future for All™ will drive our continued success as a leading provider of exterior home and outdoor living solutions.”

James Hardie now features a portfolio of high-performance, low-maintenance exterior brands, including Hardie®, TimberTech®, AZEK® Exteriors, Versatex®, StruXure®, Ultralox® and Intex®. Collectively, James Hardie brands offer incredible value, as well as endless design possibilities for homeowners looking for siding, decking, trim, railing, and pergolas.

The combination of James Hardie and AZEK creates a company with an accelerated growth rate, peer-leading profitability and robust cash generation. James Hardie intends to use its strong financial profile to support organic growth, deleverage and fund ongoing share repurchases.

With completion of the transaction, AZEK stock has ceased trading and is no longer listed on the New York Stock Exchange (“NYSE”).
