United States Lime & Minerals, Inc. (USLM) Stock Analysis
Is USLM a good investment?
United States Lime & Minerals, Inc. (USLM) has a Plutrex AI rating of 68.5/100 as of August 22, 2026, indicating a Buy consensus. The stock is halal-compliant per AAOIFI standards. Key strength: Unmatched sector profitability: operating margin of 41.0% is 117% above the industry average of 18.88%, and net margin of 35.7% is 210% above peers — reflecting durable geographic moats, high barriers to entry in lime/minerals, and pricing power that peers cannot replicate. These margins have been consistent and are structural, not cyclical.. Main concern: Forward growth deceleration remains the primary risk: 5-year EPS growth of 9.8% trails the industry average of 11.18% by 12.4%, and the collapse from 37.8% historical YoY EPS growth to 9.8% projected (a 74% reduction) suggests the recent earnings surge was non-recurring. H1 2026 revenue growth of only 2.3% ($187.0M vs. $182.8M) versus Q4 2025's 9.8% growth confirms deceleration is already materializing — the market may be paying a quality premium for a company that will grow slower than its peers going forward..
Investment Summary
United States Lime & Minerals (USLM) is an operationally exceptional but valuation-challenged industrial company. At $118.89, the stock trades at a P/E of 25.71x against a 5-year forward EPS growth rate of only 9.8%, yielding a PEG of 2.15 — more than double the fair-value threshold of 1.0. The business itself is extraordinary: operating margin of 41.0% is 117% above the industry average of 18.88%, net margin of 35.7% is 210% above peers, and the balance sheet carries zero debt against $402.6 million in cash. Q4 2025 revenues of $87.9 million grew 9.8% YoY, and H1 2026 revenues of $187.0 million grew 2.3% YoY — solid but decelerating. The analyst consensus target of $132.00 implies only 10.9% upside from current levels, insufficient for new investors given the valuation premium. USLM is a 'Hold' for existing shareholders who benefit from the quality moat, but new investors should wait for the $108-$115 entry zone where the risk/reward improves meaningfully.
Key Strengths
- Unmatched sector profitability: operating margin of 41.0% is 117% above the industry average of 18.88%, and net margin of 35.7% is 210% above peers — reflecting durable geographic moats, high barriers to entry in lime/minerals, and pricing power that peers cannot replicate. These margins have been consistent and are structural, not cyclical.
- Fortress balance sheet with zero debt (D/E = 0.0x vs. industry average 1.21x) and $402.6M in cash — USLM has no financial risk while peers carry significant leverage. Q4 2025 revenue growth of 9.8% YoY ($87.9M vs. $80.1M) and consistent dividend declarations confirm the business is executing well operationally with management confidence in cash flows.
- Relative valuation discount to peers: P/E of 25.71x is 11.3% below the industry average of 28.97x, and PEG of 2.15x is 7.0% below the industry average of 2.31x — USLM is the highest-quality company in its sector trading at a relative discount to lower-quality, more leveraged peers, providing some downside protection.
Key Concerns
- Forward growth deceleration remains the primary risk: 5-year EPS growth of 9.8% trails the industry average of 11.18% by 12.4%, and the collapse from 37.8% historical YoY EPS growth to 9.8% projected (a 74% reduction) suggests the recent earnings surge was non-recurring. H1 2026 revenue growth of only 2.3% ($187.0M vs. $182.8M) versus Q4 2025's 9.8% growth confirms deceleration is already materializing — the market may be paying a quality premium for a company that will grow slower than its peers going forward.
- Absolute valuation remains stretched: PEG of 2.15 is above the 1.0 fair value threshold, P/E of 25.71 is expensive for a 9.8% 5-year EPS grower, and the analyst consensus target of $132.00 implies only 10.9% upside from $118.89 — insufficient risk-adjusted return for new investors entering at current prices. The stock has risen 1.3% since the prior report ($117.41 → $118.89), moving further from our target entry zone of $108-$115.
Plutrex 10-Factor AI Breakdown
Fundamental Analysis
USLM's fundamentals are bifurcated: world-class profitability and financial health, but stretched valuation relative to modest forward growth. Profitability: Gross margin 48.4% (vs. industry 33.8%, +43% premium), operating margin 41.0% (vs. industry 18.9%, +117% premium), net margin 35.7% (vs. industry 11.5%, +211% premium) — these are near-monopoly-level margins reflecting durable regional pricing power. ROE of 21.4% is slightly below the industry average of 24.4%, but peers achieve higher ROE through leverage (industry D/E: 1.21x) while USLM achieves 21.4% with zero debt — far superior on a risk-adjusted basis. Financial Health: D/E of 0.0x vs. industry 1.21x; $402.6M cash; positive FCF of $47.1M. Valuation: P/E of 25.71x is 11.3% below the industry average of 28.97x, and PEG of 2.15x is 7% below the industry average of 2.31x — USLM is modestly cheaper than peers. However, the absolute PEG of 2.15 remains elevated; fair value at PEG 1.0 implies a P/E of ~9.8-13.1x, or intrinsic value of $50-$68 per share. Even at a generous quality-premium PEG of 1.5, fair value is $75-$100. Growth: Revenue growth 8.3% (vs. industry 10.0%, -17% lag); forward EPS growth next year 13.1% (vs. industry 16.5%, -21% lag); 5-year forward EPS growth 9.8% (vs. industry 11.2%, -12% lag). Historical EPS growth of 37.8% YoY is collapsing to 9.8% projected — a 74% deceleration that the market has not fully priced in.
News Sentiment
United States Lime & Minerals is quietly building a reputation as one of America's most reliable industrial businesses — but investors are starting to notice the growth is slowing down. The company's Q4 2025 results showed revenues of $87.9 million, a solid 9.8% jump from the same period a year earlier, signaling strong demand for lime and limestone products used in everything from water treatment to steel production. But the more recent H1 2026 results tell a different story: revenues of $187.0 million grew just 2.3% compared to the first half of 2025 — a significant deceleration that investors should watch carefully. Despite the slowdown, management has continued declaring regular dividends, a signal that executives remain confident in the company's cash-generating ability. USLM has also been highlighted alongside SiriusXM as one of America's rare monopolistic businesses — a designation that explains its extraordinary profit margins but also its limited growth runway. The company is also competing for infrastructure dollars alongside other construction materials firms, positioning itself to benefit from government spending on roads, bridges, and water systems. For everyday investors, the story is simple: USLM is an exceptionally profitable, debt-free company sitting on over $400 million in cash — but at current prices, you're paying a premium for quality that may not deliver the growth needed to justify the price tag.
Risk Assessment
Primary risk: Valuation compression if forward growth of 9.8% disappoints or decelerates further — H1 2026 revenue growth of only 2.3% is already a warning sign versus Q4 2025's 9.8%. At a PEG of 2.15, any earnings miss could trigger a 15-25% re-rating. Secondary risk: Infrastructure spending cycle slowdown — USLM is positioned as a beneficiary of infrastructure dollars, but if federal spending slows, demand for lime/limestone could soften. Mitigation: Zero debt and $402.6M cash provide a massive buffer; the company can sustain operations and dividends through any cyclical downturn. Stop loss at $100 (15.9% below current price) protects against a severe de-rating scenario. The regional monopoly characteristics of the lime business provide a floor on profitability even in downturns.
