Australia/US: The value of James Hardie’s Australia-listed shares fell by 15% following the announcement of a deal to buy AZEK. Financial analysts have expressed concern that the company is overpaying for more access to a slowing US housing market, according to Reuters. Analysts from Morgan Stanley said that the deal carried "a heavy premium and elevated multiple.” They added that they expected the market would be wary of synergy savings targets.

James Hardie agreed to buy AZEK for US$8.75bn, using a combination of cash and shares, on 24 March 2025. As part of the deal it will take on AZEK’s net debt of US$386m. AZEK shareholders will receive US$26.5 in cash and 1.034 ordinary shares of James Hardie for each AZEKL share they own. Upon completion of the transaction, James Hardie and AZEK shareholders are expected to own approximately 74% and 26%, respectively, of the combined company. It is hoped that the deal will create a “leading exterior and outdoor living building products growth platform.” The transaction is expected to close in the second half of 2025. It is subject to customary closing conditions, regulatory approvals and AZEK shareholder approval.

James Hardie manufactures fibre gypsum products in Europe and fibre cement products around the world. It is headquartered in Ireland, its management is based in the US and it is listed in both Australia and the US. AZEK makes exterior residential decking, siding, trim and moulding products. It is based in the US.


Vietnam: Data from the Ministry of Industry and Trade indicates that the chemical and fertiliser sector is generating 1.4Mt/yr of phosphogypsum. It identified Dinh Vu DAP Plant in Hai Phong City, Lao Cai No. 2 DAP Plant and Duc Giang - Lao Cai DAP Plant as the three largest generators of the byproduct, according to the Sài Gòn Giải Phóng newspaper. The high volumes of phosphogypsum being created require large storage areas to be built. However, companies are facing issues expanding storage sites due to environmental regulations.

The Ministry of Construction has proposed establishing accounting regulations for phosphogypsum, ash and slag from fertiliser, chemical and thermoelectric plants. It is also promoting research into using ash, slag and gypsum as replacements for aggregate in road infrastructure projects.


Philippines: The Tariff Commission (TC) will be running public hearings from late March 2025 that will consider implementing a permanent anti-dumping duty on gypsum wallboard imported from Thailand. The import tax is being considered following a petition by Knauf Gypsum Philippines in late 2023, according to the Business Mirror newspaper. In November 2024 the Department of Trade and Industry (DTI) imposed a provisional anti-dumping duty in the form of a cash bond for four months until March 2025.

In a government investigation into the situation, the subsidiary of Germany-based Knauf alleged that wallboard was imported from Thailand at ‘dumped’ prices in 2022. Other companies claimed that these imports started to negatively affect the market in 2019, leading to lower revenue and decreased profits.


UK: Etex subsidiary Siniat has inaugurated a new line at its Bristol gypsum wallboard plant in the West of England. The plant will produce 98% of Siniat’s portfolio of wallboard products for the UK and Ireland markets. It will incorporate 45% recycled content in its products, with zero waste to landfill. The company said the upgrade to the plant cost €200m.

Belgium-based Etex says that the inauguration marks its single largest production investment in its history.


Canada: Saint-Gobain Canada has appointed Jean-Claude Lasserre as its CEO, effective 1 April 2025. Lasserre brings over 30 years of experience working for Saint-Gobain across multiple continents, most recently serving as Saint-Gobain Surface Solutions CEO in France. Lasserre succeeds Julie Bonamy, who oversaw US$2.77bn in strategic acquisitions for Saint-Gobain Canada, including of metal products company Bailey Group of Companies, roofing company Building Products of Canada and siding products company Kaycan.

Lasserre said "My primary focus will be to connect with our customers and support our teams as we continue our work to offer a complete portfolio of building products with our recent acquisitions, while reinforcing our commitment to sustainable construction. We are eagerly anticipating the completion of North America's first zero-carbon wallboard plant in Sainte-Catherine, Quebec, and the imminent launch of CarbonLow drywall."


Mexico: Researchers at the National Autonomous University of Mexico have developed Sargapanel, a sargassum seaweed-based alternative wallboard. The team says that Sargapanels can replace traditional gypsum-based boards and tiles in wall and ceiling applications. It can also help to clear Mexico’s Caribbean beaches of the common organic deposit.


Russia: Türkiye-based Parget Makina has begun construction of a plaster plant for Litox under an engineering, procurement and construction (EPC) contract.

US: The National Association of Home Builders (NAHB) says that more than 71% of the US’ total annual imports of gypsum originate in Mexico. The association has highlighted the possibility of ‘scarcity and an acute, sustained rise in building materials costs’ as a result of new tariffs. The US government imposed 25% duties on products from Mexico and fellow North American country, Canada, on 4 March 2025.

NAHB said that it will ‘continue to seek a tariff exemption for building materials.’


Spain: Aminsa says that it will resume mining at its Villanasur Río de Oca gypsum quarry in Castile and León later in 2025. Local press has reported that the move aims to meet increased demand from Ireland-based James Hardie’s nearby Orejo fibre gypsum panel plant, which is undergoing an expansion.
