Fun facts about UNITED STATES LIME & MINERALS INC

Quirks, history, and lore behind USLM — the kind of stuff that makes a stock memorable.

1
The Basics
U.S. basic materials company · small-cap · listed on Nasdaq · headquartered in Texas.
2
The Numbers
Annual revenue in the range of $250–300 million, yet it runs some of the fattest operating margins in its niche — think quarry-style economics where the rock basically sells itself.
3
The History
Tracing its roots back to the late 19th century, it has quietly operated lime kilns and quarries across Texas and the American Southwest for well over a hundred years.
4
The Secret
Its customers are not consumers — they're steel mills, water treatment plants, and oil refineries that need high-calcium lime to neutralize acids, purify metals, and clean up wastewater.
5
The Lore
It sits atop some of the purest limestone deposits in North America, giving it a geological moat that no competitor can easily replicate — you can't move a mountain, after all.
6
The Giveaway
The ticker is literally four letters that stand for United States Lime — and this sleepy lime-and-limestone producer has quietly compounded shareholder returns for decades without anyone at a cocktail party ever asking what it does.
