USLM grows revenues, profit in third quarter

Revenues and gross profit were both up in the third quarter at United States Lime & Minerals (USLM).

Increases in sales volumes and average lime and limestone selling prices drove USLM’s third-quarter revenues up 14.1 percent to $102 million. The company says sales volume increases were principally due to the company’s construction, environmental and steel customers, though these were partially offset by decreases in sales volumes to USLM’s oil and gas services customers.

USLM’s gross profit in the third quarter, meanwhile, was $52.2 million – a 21.1 percent increase.

“We are pleased with the company’s continued strong financial performance in the third quarter [of] 2025,” says Timothy Byrne, president and CEO of USLM. “Demand from our construction customers remained solid, supported by the construction of large data centers in the regions that we serve. Looking ahead, we anticipate a more mixed demand picture, with ongoing data center construction demand being partially offset by softer demand from some of the other industries that we serve.”
