About United States Lime & Minerals INC

United States Lime & Minerals, Inc. (USLM) is a U.S.-listed industrial materials company traded on the NASDAQ market in the United States. For French-speaking investors, it is best viewed as a niche basic-materials operator with a focus on lime and limestone products used across industrial, environmental, agricultural, and construction end markets. The company is headquartered in Dallas, Texas, and was incorporated in 1950. Its business is organized around two segments: Lime and Limestone Operations, and Natural Gas Interests tied to acreage in Texas.

These products are essential inputs for a wide range of processes, including highway and building construction, steel and other metals, paper and glass manufacturing, municipal water and wastewater treatment, flue gas treatment and emissions control, roofing, agriculture, and certain oil and gas services. That customer mix gives the company broad end-market exposure, while still keeping its business centered on a relatively narrow product set. ([uslm.com](https://www.uslm.com/main.html?utm_source=openai)) Geographically, the company remains heavily focused on the central United States, with plants and distribution facilities in Arkansas, Colorado, Louisiana, Missouri, Oklahoma, and Texas. This regional footprint is strategically important because lime and limestone are bulky, logistics-sensitive products that are typically sourced near demand centers when possible. USLM’s competitive position is therefore less about global scale and more about local asset quality, stable supply relationships, and proximity to customers in its served markets. ([uslm.com](https://www.uslm.com/?utm_source=openai)) From an industry perspective, USLM is a specialized materials company rather than a diversified mining conglomerate. It operates open-pit quarries and, at certain locations, an underground mine, supported by company-owned plants and transportation assets. The business benefits from vertical integration in a number of its markets and from long-standing commercial relationships in construction, environmental services, and industrial processing.

In 2024, the company began construction of a new vertical kiln and related infrastructure at its Texas Lime Company plant, with estimated project cost of about $65 million and expected startup in the summer of 2026. USLM also reported revenue growth through 2025, including an increase in the third quarter and first nine months, and continued to disclose insider activity through SEC Form 4 filings, which is relevant for monitoring alignment and ownership dynamics. Overall, the name offers a conservative, U.S.-centric industrial materials profile with a visible capital project pipeline and exposure to both cyclical and defensible end markets.
