GGG vs KAI: Which Is the Better Buy in 2026?

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.

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. GGG and KAI 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 GGG and KAI 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. Walnut is not an investment adviser.

Graco Inc. designs, manufactures, and markets specialized equipment used to pump, meter, mix, dispense, and spray fluids and powders. The business runs across three segments: Contractor (paint sprayers, foam and roofing systems, sold heavily through home-center and paint-store channels), Industrial (liquid and powder finishing, lubrication, and process pumps for factories), and Expansion Markets (semiconductor pumps, high-pressure oil and gas valves, and environmental equipment). Its products are often low-cost but mission-critical parts of a customer's larger process, which gives Graco strong pricing power, high gross margins in the low-50s percent range, and a long record of returning cash through dividends and buybacks.

Kadant Inc. builds the equipment that keeps industrial process lines running, organised into three reportable segments. Flow Control sells rotary sealing devices, steam systems, doctor blades, cleaning and filtration gear into packaging, paper, tissue, food, energy and defense plants, and produced ~$100M of revenue in the second quarter of 2026. Industrial Processing, the largest segment at ~$144M, supplies stock-preparation and recycling equipment for paper and paperboard plus stranders and debarkers for wood processing. Material Handling, at ~$69M, covers vibratory conveying, baling and related systems. The common thread is that each machine wears out consumable components, so Kadant sells replacements for decades after the original sale. Parts and consumables were ~68% of second-quarter revenue and ~72% of bookings.

Both fit overlapping themes, but they are not interchangeable. The useful comparison is which set of drivers and risks you want exposure to.

• GGG drivers: Pricing power and niche moats; Acquisition-led growth.
• KAI drivers: The aftermarket annuity; Serial acquisition of niche installed bases.

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: Organic sales have been declining, so reported growth leans heavily on acquisitions and currency, which can mask underlying softness. For KAI, capital-order timing is the single largest swing factor, and organic bookings already turned slightly negative in the second quarter.

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 GGG if you believe its drivers more; KAI 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 GGG and KAI guides.

GGG. Graco trades around $74 per share with a market cap near $12.3 billion, at roughly 24 times trailing earnings, a premium that reflects its quality and consistency. Q1 2026 revenue of about $540 million grew 2.3 percent, but that was entirely acquisitions and currency offsetting a roughly 6 percent organic decline, and it missed analyst estimates. Gross margin slipped about 60 basis points on higher product costs, lower factory volume, and tariffs.

KAI. At roughly ~$334 a share the market is paying about ~36 times trailing earnings and ~27 times the midpoint of guided 2026 adjusted EPS, a premium to the average industrial machinery name that rests on the recurring-parts mix. The bridge from guided GAAP EPS to adjusted EPS is ~$2.65 per share, so which number an investor anchors to changes the multiple by roughly a third. Free cash flow of ~$43M in the quarter and a covenant leverage ratio of ~1.72 leave capacity for further deals.

Headline figures (approximate, JULY 2026): GGG shows revenue (ttm) ~$2.2B, q1 2026 revenue ~$540M (+2.3% YoY), q1 2026 diluted eps ~$0.70, market cap ~$12.3B; KAI shows revenue (ttm) ~$1.15B, diluted eps (ttm) / p/e ~$9.30 / ~36x, 2026 guidance revenue ~$1.19B to ~$1.21B, adjusted EPS ~$12.43 to ~$12.68, adjusted ebitda margin (q2 2026) ~21.8%.

GGG and KAI 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 GGG and KAI exposure against your real portfolio. It is not an investment adviser.
