US: Eagle Materials recorded sales of US$1.83bn in the first nine months of the 2026 financial year (FY2026), up by 2% year-on-year. A 5% year-on-year rise in costs, to US$1.28bn, offset sales growth to precipitate an 8% decline in net earnings, to US$364m. Gypsum wallboard sales fell by 10% in value, to US$581m, and by 8% in volume. The group reported ‘good progress’ on an on-going upgrade to its Duke gypsum wallboard plant in Oklahoma.

Eagle Materials issued US$750m of 10-year senior notes with an interest rate of 5% during the quarter, which extended its total debt maturity schedule and increased committed liquidity. A portion of the proceeds repaid its bank credit facility. It ended 2025 with debt of US$1.8bn, net debt of US$1.4bn and a net leverage ratio of 1.8 times.

President and CEO Michael Haack said "Despite a mixed construction environment, Eagle's portfolio of businesses continued to perform well during the third quarter of FY2026. While the residential construction market was challenged, federal, state and local spending on public infrastructure projects and private non-residential construction remained elevated. Our low-cost operations continue to generate strong cashflow that we are investing to advance our operational efficiency and our low-cost position."

US: Germany-based Grenzebach has received an order from American Gypsum Company for the construction of a new wallboard production line at the its Duke, Oklahoma, plant. The new line will expand the Duke plant’s capacity by 25%, while reducing its operating costs by 20%. American Gypsum Company intends for the expansion to help it to meet ‘rising demand’ in its South US and US Sunbelt regions.

Grenzebach will deliver a ‘customised complete plant,’ equipped with natural gypsum drying facilities and two calcination plants, by mid-late 2027. The supplier noted the order as its largest for the building materials sector to date.

“This major project will be implemented across the group, with our locations in North America, Germany, India and Romania working closely together,” said John Corsi, CEO of Grenzebach North America. “A key factor in securing this project was the strong sales cooperation between our Grenzebach Corporation and Millennium Control Systems teams in the US and our centre of competence for Building Materials at Grenzebach BSH in Germany. This international collaboration underscores our expertise and capability as a strong, global operating partner.”

Saudi Arabia: Germany-based Knauf has announced the planned acquisition of a majority stake in United Mining Industries Company (UMI), followed by all other outstanding shares in the company. UMI is a market-leading producer of gypsum products and other building materials domestically and across Gulf Cooperation Council (GCC) and other Middle Eastern markets. A planned initial investment would give Knauf a 63% majority stake in UMI. After completion of this, Knauf intends to submit an offer to acquire up to 100% of shares in UMI.

Knauf has been active in the Middle East for 30 years. It established its first gypsum wallboard plant regionally at Ras Al Khaimah, UAE, in 2008. Saudi Arabia is a key growth market for the group and a ‘central pillar’ of its regional strategy.
