United States Lime & Minerals Inc. Common Stock (USLM) fair value

ACCE thesis

United States Lime & Minerals produces quicklime and hydrated lime from its own limestone reserves in Texas, Oklahoma, Arkansas, Nevada and other states, selling mainly to steel mills, water treatment plants, construction and environmental customers. The moat is the reserve base itself: lime plants sit next to quarries that have decades of permitted stone, and new capacity is slow and expensive to permit, so incumbents face little pressure from new entrants. Revenue growth of 8.3% and an operating margin of 41.0% show that the pricing power is real and that volume and price are both contributing. The stock trades at 22.9 times trailing earnings but 15.2 times forward earnings, which implies the market expects earnings to step up meaningfully. That gap, along with a 21.3% return on equity, is the reason to open the filings and check whether the forward estimates are credible, and how much of the margin depends on steel and construction demand holding up.
