Income Statement Analysis: The Bottom-Line Duel
This income statement comparison reveals the true operational efficiency and profitability dynamics of Parker-Hannifin Corporation and A. O. Smith Corporation.
Parker-Hannifin Corporation Analysis
Parker-Hannifin sustains robust revenue near $19.85B in 2025, slightly down from $19.93B in 2024, yet net income surges 24.1% to $3.53B. Gross margin holds steady at 36.85%, indicating efficient cost control. EBIT margin of 22.75% and a net margin of 17.79% demonstrate strong bottom-line momentum, with EPS up 24.18% reflecting operational leverage.
A. O. Smith Corporation Analysis
A. O. Smith posts modest revenue growth to $3.83B in 2025, up from $3.82B in 2024, with net income increasing 2.4% to $546M. The firm maintains a higher gross margin at 38.83%, but a lower EBIT margin near 19.04% signals tighter operating expenses.

Efficiency & Valuation Duel: The Vital Signs
Financial ratios act as the company’s DNA, revealing hidden risks and operational excellence essential for discerning investors.
Parker-Hannifin Corporation
Parker-Hannifin shows a strong ROE of 25.8% and solid net margins at 17.8%, indicating robust profitability. However, its P/E of 25.4 suggests the stock trades at a premium, possibly stretched. Dividend yield is modest at 0.96%, reflecting a cautious shareholder return strategy amid balanced reinvestment in growth.
A. O. Smith Corporation
A. O. Smith delivers comparable ROE at 25.6% with a respectable net margin of 14.3%. Its P/E of 17.1 signals a more reasonable valuation, supporting efficiency. The company offers a healthier dividend yield of 2.09%, highlighting a stronger commitment to returning cash while maintaining favorable leverage and operational metrics.
Premium Valuation vs. Operational Safety
Parker-Hannifin commands a premium valuation with excellent profitability but limited yield. A. O. Smith balances attractive returns and valuation with stronger dividend payouts and lower leverage. Investors seeking growth with income might prefer A. O. Smith’s profile, while those favoring operational strength at a premium may lean toward Parker-Hannifin.
Which one offers the Superior Shareholder Reward?
I compare Parker-Hannifin (PH) and A. O. Smith (AOS) on dividends, payout ratios, and buybacks for 2026. PH yields 0.96% with a 24.4% payout, backed by strong free cash flow coverage (2.91x). AOS pays a higher 2.09% yield with a 35.8% payout but has lower free cash flow coverage (2.31x). Both maintain consistent buyback programs enhancing total returns; PH’s capital allocation balances dividends and buybacks prudently, while AOS’s lower debt and stronger solvency support sustained distributions. I see PH’s model as more sustainable over cycles, but AOS offers a more attractive total return profile in 2026 due to its higher yield and robust financial health.
