Analysis Summary

This looks like a sturdy business the market has overlooked. A high return on invested capital, a clean balance sheet with next to no debt, and a wide moat in basic materials all point to durable profitability. While the current dividend yield is modest, the consistent growth and opportunity for future capital allocation due to its financial strength makes USLM a potential candidate for further investigation.
