ON BOARD 2019 August, Edition 16 | Page 2

ON BOARD Edition 16 15 Contents I am pleased to confirm the news this week that USG Boral and Knauf Gypsum propose to form a new expanded joint venture in Asia to be named USG Boral Building Products. The joint venture will not include the USG Boral Australian and New Zealand businesses, which will change to 100% Boral ownership. What does this mean for us? As of November, the USG Boral ANZ business will become a Boral company. The company name and brand will remain unchanged. We will continue to trade as USG Boral and provide the same distinctive brands, product lines and services our customers have come to know and expect. All current ANZ customers and suppliers have been informed of the ownership change and advised that it’s business as usual. USG Boral has won two coveted Good Design Awards at the 2019 Australian Awards in Sydney. Our SHEETROCK ® Dust Control Compound and Ensemble™ Acoustical Ceiling System both received Good Design Awards for excellence in design – a terrific endorsement of our commitment to product innovation and functional and aesthetic design. We will provide you with periodic updates as the transition to 100% Boral ownership progresses. As always, please don’t hesitate to contact me if you have any questions. Yours sincerely, There are no expected changes to the USG Boral leadership team apart from Calvin Ng, IT Director ANZ, who will return to KL. I’d like to thank Calvin for his commitment to the Australian and New Zealand businesses over the past 2 years and wish him well with the new JV. Interviews are underway for a new Chief Information Officer. Tony Charnock Senior Vice President Asia Pacific In other news, Gerard Moran retires after 47 years with USG Boral.
