NPO vs PH: Which Is the Better Buy in 2026?
Last updated August 2026
Short answer
PH is the larger of the two ($123.13B market cap): the incumbent the market prices for continued execution (28.63x forward earnings, beta 1.11). NPO is the smaller challenger ($7.33B), priced similarly on forward earnings (31.81x): more room to run, but more to prove. The real question is which set of drivers you believe, and whether owning one (or both) leaves you over-concentrated.
NPO vs PH: the tie-breaker metrics
Same yardstick, side by side (as of August 2026). Valuation lined up like this is most meaningful for two names in the same corner of the market, which these are. Figures are approximate; verify before investing.
| Metric | NPO | PH | What it tells you |
|---|---|---|---|
| Market cap | $7.33B | $123.13B | Size. The larger name is the incumbent; the smaller has more room to grow and more to prove. |
| Forward P/E | 31.81 | 28.63 | Valuation on next year's expected earnings, the same yardstick for both. Lower is cheaper for that growth; higher means the market is paying up. |
| Trailing P/E | 168.12 | 35.97 | Valuation on the last 12 months. A big drop from trailing to forward means the market expects earnings to jump, so more growth is already in the price. |
| Beta | 1.56 | 1.11 | Volatility vs the market. Above 1 swings harder than the index; below 1 is steadier. Higher beta means bigger drawdowns to hold through. |
| Price vs 52-week range | 77% of range | 83% of range | Where today's price sits between the 52-week low and high. Near the high is momentum with less margin of safety; near the low is out of favor or a discount, depending on why. |
| Price / book | 4.62 | 8.43 | How much you pay over book value. Very high can signal an asset-light, high-return business or a rich price. |
Before you buy: how NPO and PH affect your concentration
The metrics above tell you which is the marginally better business. The bigger risk for most people is not picking the slightly worse stock, it is over-concentrating. NPO and PH share themes, so owning both, or adding either to what you already hold, can quietly push a large share of your portfolio into one bet.
This is the part a generic comparison page cannot answer, because it depends on what you own. Connect your brokerage and Walnut shows your real, combined NPO and PH exposure, flags overlap with your existing positions, and tells you if adding one would tip you past a concentration you are comfortable with, read-only by default, with your login staying at your broker.

What does Enpro (NPO) do?
Enpro Inc. designs and manufactures engineered industrial products across two reporting segments. Sealing Technologies, roughly two-thirds of revenue, sells gaskets, seals, wheel-end components and compositional analysis equipment under the Garlock, STEMCO and Technetics Group brands into general industrial, aerospace, commercial vehicle, food and biopharmaceutical end markets. Advanced Surface Technologies (AST) is the semiconductor-facing half of the story: NxEdge, Technetics Semi, LeanTeq and Alluxa supply precision cleaning, coating and refurbishment services for chamber components used in leading-edge chip production, plus optical thin-film coatings. Both segments sell consumable or service-like content rather than capital equipment, which is why the company keeps talking about recurring aftermarket demand rather than one-off machine sales.
What does Parker Hannifin (PH) do?
Parker Hannifin makes motion and control technologies: hydraulics, pneumatics, filtration, sealing and electromechanical systems used across industrial machinery and aerospace.
NPO vs PH: how do they differ?
Both fit overlapping themes, but they are not interchangeable. The useful comparison is which set of drivers and risks you want exposure to.
- NPO drivers: Advanced Surface Technologies and leading-edge chip demand; Sealing Technologies margin durability and bolt-on acquisitions.
- PH drivers: Aerospace is now a major earnings engine; Aftermarket and replacement demand.
Which fits which kind of investor
A faster-growing, richer-valued name usually swings harder, so it suits a longer horizon and a higher tolerance for volatility; a steadier, more cash-generative business suits a more conservative or income-minded investor. The honest test is which set of risks you could hold through a drawdown: Valuation carries most of the downside here: at roughly 36 times the midpoint of 2026 adjusted EPS guidance and around 23 times guided adjusted EBITDA, the shares assume the semiconductor upcycle persists. For PH, industrial demand is cyclical and tracks capital spending, manufacturing output and construction.
NPO or PH: which should you pick?
Growth-minded investors who believe the theme has years to run tend to accept the richer multiple for more upside; value-minded investors lean toward the cheaper forward earnings and steadier profile. Pick NPO if you believe its drivers more; PH if you believe its. Many investors hold both, but since they share themes, that is a concentrated bet, not diversification. Decide deliberately and check overlap. For the full detail, see the NPO and PH guides.
NPO vs PH: the full fundamentals
NPO. Against a market capitalization near ~$7.3 billion, Enpro trades at roughly 36 times the midpoint of its 2026 adjusted EPS guidance and about 6 times TTM revenue, multiples that sit well above where diversified sealing manufacturers historically cleared. Trailing GAAP earnings are a poor guide right now because a ~$67.2 million pension settlement charge and higher environmental reserves suppressed reported net income to ~$44 million over the last twelve months. The quarterly dividend of $0.32 per share annualizes to roughly a 0.4% yield, so income is incidental to the case.
PH. Parker is a diversified industrial whose story in recent years has been margin expansion and the aerospace mix shift rather than rapid revenue growth. Verify current segment margins and leverage.
Headline figures (approximate, August 2026): NPO shows revenue (ttm) ~$1.22B, q2 2026 sales ~$338.8M (+17.6% YoY, ~10.9% organic), adjusted ebitda margin (q2 2026) ~25.6%, 2026 adjusted eps guidance ~$9.30 to ~$9.80; PH shows business model Motion and control components across industrial and aerospace, key mix shift Aerospace substantially larger after the Meggitt acquisition, revenue quality Large aftermarket and replacement component, balance sheet Carries acquisition debt; verify current leverage.
The bottom line: NPO vs PH
NPO and PH are related but distinct: same themes, different businesses and risks. Neither wins in the abstract; the right pick is whichever thesis you actually believe, sized so you are not over-concentrated in one theme. Walnut can show your combined NPO and PH exposure against your real portfolio. It is not an investment adviser.

FAQ
What is the difference between NPO and PH?
+
Enpro Inc. Parker Hannifin makes motion and control technologies: hydraulics, pneumatics, filtration, sealing and electromechanical systems used across industrial machinery and aerospace. They show up together because they share investment themes, but they are different businesses, so the better fit depends on which thesis you are expressing.
Is NPO or PH the better stock?
+
Neither is universally better. PH is the larger incumbent; NPO is the smaller challenger and looks pricier on forward earnings. Walnut is informational, not investment advice. Compare what each does, the tie-breaker metrics above, and the risks, then decide which fits your thesis and what you already own.
Which is cheaper, NPO or PH?
+
On forward P/E (as of August 2026), NPO trades at 31.81x and PH at 28.63x, so PH is the cheaper of the two on next year's expected earnings. A lower multiple is not automatically the better buy: a richer valuation can be justified by faster growth, and a lower one can reflect real risk. Weigh the multiple against how fast each business is compounding.
Should you own both NPO and PH?
+
Because they share themes, owning both concentrates you in that theme. That can be intentional (a focused bet) or accidental (less diversification than it looks). Walnut can show your combined exposure across both, and whether adding either over-concentrates you, before you buy.
What are the risks of NPO vs PH?
+
NPO: Valuation carries most of the downside here: at roughly 36 times the midpoint of 2026 adjusted EPS guidance and around 23 times guided adjusted EBITDA, the shares assume the semiconductor upcycle persists. AST demand is tied to a concentrated set of leading-edge chipmakers whose capital spending can pause abruptly, and a digestion phase would hit the highest-growth, highest-expectation part of the portfolio first. Trailing GAAP results look far weaker than adjusted results, with TTM GAAP diluted EPS near ~$2.06 against ~$9.55 of guided adjusted EPS, a gap created largely by a ~$67.2 million non-cash pension settlement charge in the fourth quarter of 2025 and a ~$16.1 million increase in legacy environmental reserves in the second quarter of 2026. Those legacy environmental obligations, inherited from decades of industrial operations including the asbestos history resolved through the Garlock trust settlement, can be re-estimated upward again. Cyclical pressure also persists in North American commercial vehicle markets and European general industrial and food and biopharmaceutical demand, and the recent acquisition cadence adds integration risk on top of it. PH: Industrial demand is cyclical and tracks capital spending, manufacturing output and construction. The Meggitt acquisition added meaningful debt, so deleveraging progress matters. Aerospace revenue depends on air traffic and defence budgets. As a global manufacturer, Parker is exposed to currency, tariffs and supply-chain disruption.
