A. O. Smith: Hot Water, Cold Price
The business and its moat
Whatever AI rewrites over the next decade, the odds that American households give up baths and hot water are close to zero. Over 80% of A. O. Smith’s North American revenue comes from non-discretionary replacement demand — things break, people replace them. Demand is effectively reserved by the installed base.
The moat proved itself recently. In 2025 the company passed through rising steel costs and tariffs with 4–7% price increases, and North America grew 6% on price alone. There is no route by which AI collapses the marginal cost of physically heating water. The moat rests not on information asymmetry but on the trust of plumbing contractors and a distribution network — an unglamorous asset, which is usually where the durable ones live.
Earning power and capital allocation
The five-year average ROE is 25.6% — a level few asset-heavy manufacturers sustain for a decade. Owner earnings screen at a first-pass $560 million, though recast against the company’s own 2026 guidance (adjusted EPS of $3.70–3.85) they come closer to $500–540 million. The most recent quarter’s free cash flow was a modest $110 million.
Capital allocation is respectable: over thirty consecutive years of dividend increases, a D/E ratio of 0.08 (effectively debt-free), and buybacks raised 50% to $300 million a year. There is no history of empire-building acquisitions at top prices. One quibble: repurchasing shares at an average cost of around $67 is buying above my estimate of intrinsic value. Good discipline; loose pricing.
Valuation and margin of safety
Market cap stands at $8.6 billion — $63.08 a share, 17.6 times earnings. Wall Street’s consensus is HOLD, with eleven analysts averaging a $69.91 target.
On a normalized basis, owner earnings yield runs 5.8–6.3%, against a 10-year Treasury at 4.74%. Applying twelve times normalized owner earnings and a 30% margin of safety gives an intrinsic value of $6.0–6.5 billion ($44–48 a share); the discounted buy price would be a market cap of $4.2–4.5 billion, or $31–33 a share.
The gap between the street’s target and mine is telling. Analysts are looking at easier year-over-year comparisons ahead. What they are not pricing: China sales accelerating to minus 28% year-over-year, with the company entering a strategic review of that business. Against a conservative North America-only intrinsic value centered on $6.25 billion, today’s market cap is roughly a 38% premium. A yield 1.3 percentage points above the Treasury is not “cheap” — it is merely “not expensive.” A margin of safety is measured against intrinsic value, not against a bond, and right now that margin is negative.
Word for today
Good news — a bigger buyback, the start of the China cleanup — does not turn a bad price into a good one. I am not waiting for a great company; I am waiting for the day a great company gets cheap.
Verdict
Pass. A fine business at a price that has already said yes too early.
Correction (2026-09-03): market cap and owner-earnings yield restated at the price on the verdict date ($62.74 on 2026-08-24; the 2026-08-24 screening snapshot adjusted for price): market cap ≈ $8.6 billion (the article said $8.6 billion), owner-earnings yield ≈ 6.55% (the article said 6.3%) vs the 10-year Treasury at 4.70% — verdict unchanged.
