AIT vs MSM: Which Is the Better Buy in 2026?
Last updated October 2026
Short answer
AIT is the larger of the two ($12.15B market cap): the incumbent the market prices for continued execution (25.05x forward earnings, beta 0.85). MSM is the smaller challenger ($7.28B), priced similarly on forward earnings (23.60x): 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.
AIT vs MSM: the tie-breaker metrics
Same yardstick, side by side (as of October 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 | AIT | MSM | What it tells you |
|---|---|---|---|
| Market cap | $12.15B | $7.28B | Size. The larger name is the incumbent; the smaller has more room to grow and more to prove. |
| Forward P/E | 25.05 | 23.60 | 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 | 30.20 | 31.49 | 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 | 0.85 | 0.81 | 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 | 68% of range | 94% 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 | 6.72 | 5.13 | 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 AIT and MSM 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. AIT and MSM 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 AIT and MSM 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 Applied Industrial Technologies (AIT) do?
Applied Industrial Technologies has been distributing bearings and power transmission components since 1923 (it traded as Bearings Inc. until 1997) and now operates in two segments. Service Center, about 66% of fiscal 2025 sales, is the maintenance, repair and operations business: a network of local branches across North America, Australia and New Zealand stocking bearings, motors, belting, drives, couplings, pumps, hoses and filtration for customers' existing equipment. Engineered Solutions, the other 34%, is the more technical half, covering fluid power systems, flow control, automation design and integration, and it carries higher growth and a different competitive set. The pitch to customers is expertise rather than price: engineers, fluid power specialists and fabrication shops that keep production lines running. Revenue is heavily domestic, with roughly $4.0 billion of fiscal 2025's $4.56 billion coming from the United States, and no single customer accounts for more than 5% of sales.
What does MSC Industrial Direct (MSM) do?
MSC Industrial Direct was founded in 1941 by Sidney Jacobson and is headquartered in Melville, New York, with a second head office in Davidson, North Carolina. It operates as MSC Industrial Supply Co. and distributes roughly 2.5 million products: cutting tools, measuring instruments, tooling components, abrasives, fasteners and production hardware, hand and power tools, safety and janitorial supplies, plumbing, electrical and material-handling products. Its historical identity is metalworking, the consumable tooling machine shops and manufacturers burn through every shift. On top of that it layers a service model of in-plant staff, vending machines and vendor-managed bins that put MSC inside customers' facilities. Customers range from small independent machine shops, which the company calls its Core Customer, to national manufacturing accounts and public-sector buyers. The fiscal year ends around the end of August, and fiscal 2025 net sales were ~$3.77 billion from more than 7,000 associates.
AIT vs MSM: 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.
- AIT drivers: Mix shift toward Engineered Solutions; Consolidating a fragmented market.
- MSM drivers: Margin recovery and "doing more with less"; The Core Customer and National Accounts.
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: The business is cyclical in a way that no amount of execution removes: sales follow industrial production, capacity utilization and customer capital budgets, and end markets such as oil and gas, mining, primary metals and forest products can turn sharply. For MSM, mSC is a cyclical business.
AIT or MSM: 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 AIT if you believe its drivers more; MSM 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 AIT and MSM guides.
AIT vs MSM: the full fundamentals
AIT. The multiple has come in since August even as the stock rose over the year: ~30 times trailing and ~25 times forward earnings, ~20 times EBITDA and ~2.5 times sales, because earnings caught up after the June-quarter beat. That is still a premium for a distributor that grew organically in the mid single digits for most of fiscal 2026. Fiscal first quarter 2027 results arrive October 27, 2026, with consensus at ~$2.89 of EPS on ~$1.29 billion of sales, and the six covering analysts carry a mean target near $398.
MSM. At ~$129 the shares trade near ~31x trailing GAAP earnings and roughly ~30x trailing adjusted EPS of ~$4.33 (the ~$3.24 earned in the first three quarters of fiscal 2026 plus ~$1.09 in the fourth quarter of fiscal 2025), and about ~23x forward estimates, a premium to MSC's own history that prices in margin recovery. The balance sheet is conservative, with ~$507 million of total debt against ~$74 million of cash on May 30, 2026, and management targets ~95% free cash flow conversion for the year. Fourth-quarter results on October 22, 2026 will be compared with ~$978 million of sales and ~$1.09 of adjusted EPS a year earlier.
Headline figures (approximate, October 2026): AIT shows revenue (ttm, fiscal 2026) ~$4.97B, up ~9% for the year and ~10% in the June quarter, net income (ttm) ~$415M, ~8.4% net margin (~11.8% operating), diluted eps ~$11.02 trailing; June quarter $3.17 vs $2.92 expected, market cap ~$12.2B at ~$331 per share; MSM shows revenue (ttm, through q3 fy2026) ~$3.91B, net sales (q3 fy2026, ended may 30, 2026) ~$1.05B (+7.8% YoY), adjusted eps (q3 fy2026) ~$1.43 (vs ~$1.08), adjusted operating margin (q3 fy2026) ~10.6% (vs ~9.0%).
The bottom line: AIT vs MSM
AIT and MSM 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 AIT and MSM exposure against your real portfolio. It is not an investment adviser.

FAQ
What is the difference between AIT and MSM?
+
Applied Industrial Technologies has been distributing bearings and power transmission components since 1923 (it traded as Bearings Inc. MSC Industrial Direct was founded in 1941 by Sidney Jacobson and is headquartered in Melville, New York, with a second head office in Davidson, North Carolina. 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 AIT or MSM the better stock?
+
Neither is universally better. AIT is the larger incumbent; MSM is the smaller challenger and looks cheaper 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, AIT or MSM?
+
On forward P/E (as of October 2026), AIT trades at 25.05x and MSM at 23.60x, so MSM 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 AIT and MSM?
+
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 AIT vs MSM?
+
AIT: The business is cyclical in a way that no amount of execution removes: sales follow industrial production, capacity utilization and customer capital budgets, and end markets such as oil and gas, mining, primary metals and forest products can turn sharply. Trade policy and tariffs are an explicit uncertainty management has folded into its outlooks, and they cut both ways, since inflation can help distributor revenue while compressing volumes. LIFO accounting on US inventories makes gross margin lumpy, with $5.6 million of LIFO expense in the March 2026 quarter against $2.2 million a year earlier. Valuation remains the most concrete risk: at roughly 30 times trailing earnings and ~20 times EV/EBITDA, with the shares up ~35% over the past year and within ~12% of the 52-week high of ~$375, the stock trades well above the multiple industrial distributors historically commanded, which leaves little cushion if organic growth reverts to the low single digits it ran at in fiscal 2024 and 2025. The next test is the October 27 report, where consensus looks for ~$2.89 of EPS. Acquisition-led strategies also carry integration and goodwill risk, and Applied carried ~$705 million of goodwill and ~$323 million of intangibles against ~$1.86 billion of equity as of spring 2026, while debt has since risen to ~$483 million. MSM: MSC is a cyclical business. When factory activity and the ISM manufacturing index weaken, consumable tooling and MRO spend falls quickly, and the 2023 to 2025 period showed how fast margins compress when volumes decline against a largely fixed distribution cost base. The fiscal 2026 rebound leaned on price, so as tariff-related increases are lapped, growth could slow sharply unless underlying volumes keep improving, and gross margin could come under pressure if customers resist further increases or supplier costs rise faster than MSC can pass them through. Inventory rose ~$38 million in the first three quarters, which ties up cash if demand softens. Competition is intense from Grainger and Fastenal, which run at higher margins, and from Amazon Business and other online channels that compress pricing on commodity items. Leadership is new at the top: a CEO in her first year and a CFO who started in September 2026 will set fiscal 2027 targets. The company is also defending a 2025 New York state-court suit over the elimination of its dual-class share structure. Finally, at roughly 30x trailing earnings after a ~64% rise from the January low, and with a dividend payout ratio above 80%, the valuation leaves less room for a soft guide than it did a year ago.
