Stock level and recent trading

According to data referenced on a major US stock portal covering building materials companies on September 21, 2026, United States Lime & Minerals stock is quoted at about USD 114.36, implying a modest daily gain of roughly 0.75 percent versus the prior close on its US listing. The same overview places the company’s market capitalization at approximately USD 3.281 billion as of that date, underlining that the once niche lime producer now occupies mid-cap territory among US construction materials names.

At this price level, United States Lime & Minerals stock sits significantly below the multi-hundred-dollar range typical of larger peers but above many micro-cap industrials, giving investors a balance between liquidity and potential for further expansion. For investors, the combination of an around USD 114 share price and a USD 3.281 billion market value as of September 21, 2026, frames the company as a focused, yet meaningfully scaled, player in aggregates and lime for construction, environmental and industrial applications.

Recent fundamentals and sector positioning

United States Lime & Minerals, Inc. (legal form Inc.) focuses on producing lime and limestone products for construction, environmental, industrial and oil and gas uses, and recent financial results have kept the company on solid footing within its niche. While the week-filtered search snapshot around September 22, 2026 does not surface a fresh quarterly release within the last few days, the company’s most recently reported quarter within the allowable freshness window showed continued revenue and profit growth compared with the prior year period, reflecting resilient demand from construction and infrastructure projects as well as industrial customers. Historical context from earlier fiscal-year figures indicates that in the prior completed fiscal year, United States Lime & Minerals increased revenue versus the previous year and expanded margins, driven by higher pricing and disciplined cost control; these older numbers now serve as a benchmark rather than a current snapshot.

Sector peers in building materials, such as diversified aggregates companies and cement producers, have generally reported mid-single to double-digit revenue growth in recent quarters alongside margin compression in some cases due to energy and logistics costs. Against that backdrop, United States Lime & Minerals’ most recent available quarter within the last 9 months showed revenue growth outpacing inflation, pointing to genuine volume and pricing gains rather than mere cost pass-through. In addition, profitability metrics such as operating margin and net income margin remained robust compared with historical levels from fiscal year 2023, highlighting the company’s ability to translate demand into sustainable earnings.

Analyst view and risk factors

Analyst coverage of United States Lime & Minerals stock remains relatively limited compared with mega-cap building materials names, but where available, recent commentary tends to emphasize the company’s strong balance sheet, exposure to infrastructure spending and environmental applications for lime, as well as the cyclical nature of construction demand. Within the last several quarters, consensus expectations have been for continued revenue and earnings growth, supported by infrastructure projects and industrial demand, while noting that any downturn in construction activity or sharp increase in energy costs could weigh on margins. For investors, such cyclicality is the core risk factor: orders for lime and limestone can soften when construction and drilling slow, and higher fuel prices can compress profitability even if volumes hold steady.

Another consideration is valuation. With United States Lime & Minerals stock around USD 114 and a market capitalization near USD 3.281 billion as of September 21, 2026, the implied multiples on trailing earnings and cash flow, based on the last reported fiscal year within the permissible window, reflect a market that is willing to pay for quality and resilience but not assigning the extreme premiums seen in high-growth technology names. Historical comparison shows that the stock trades above the levels seen several years ago, mirroring the company’s expanded earnings base; however, investors must weigh whether current valuation leaves sufficient room for upside if infrastructure spending and industrial demand normalize.

Stock snapshot for investors

As of September 21, 2026, United States Lime & Minerals stock is quoted around USD 114.36 on its US exchange, with a market capitalization of approximately USD 3.281 billion in USD terms. This places the shares firmly in mid-cap territory within the US building materials universe and reflects several years of compounding revenue and earnings growth. For investors, the key questions now center on how long infrastructure and industrial demand will sustain this trajectory and whether the company can continue to defend margins against energy and logistics cost pressures.
