GRWG vs MUSA: 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. GRWG and MUSA 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 GRWG and MUSA 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.

GrowGeneration Corp. is a US-based developer, distributor, and retailer of products for hydroponic and organic indoor and outdoor gardening. Its customers range from large commercial cannabis and produce cultivators to smaller growers, and its catalog spans nutrients, grow lights, environmental controls, growing media, and related equipment. Historically the company grew rapidly by acquiring and rolling up regional hydroponics stores, but as the cannabis boom cooled it has been restructuring: closing or consolidating underperforming retail locations, cutting costs, and reorienting around commercial business-to-business distribution and its own proprietary brands.

Murphy USA operates around 1,803 stores as of March 2026, split between roughly 1,655 Murphy USA and Murphy Express fuel-focused kiosks and 148 QuickChek convenience stores concentrated in the US Northeast. The core model is deliberately low-cost: many locations sit directly adjacent to Walmart Supercenters, drawing value-conscious drivers with competitive pump prices, then converting that traffic into higher-margin merchandise sales like tobacco, snacks, and beverages. In the first quarter of 2026 the company reported net income of about $136 million (~$7.28 per diluted share) on revenue of roughly $4.82 billion, up about 21% year over year, driven largely by stronger fuel margins.

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

• GRWG drivers: Proprietary-brand and margin mix shift; Pivot to B2B and digital distribution.
• MUSA drivers: Structural fuel-margin advantage; New-store unit growth.

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: GrowGeneration's demand is heavily exposed to the US cannabis-cultivation cycle, which has suffered from oversupply, falling wholesale prices, and reduced grower investment; a prolonged downturn would pressure revenue regardless of internal execution. For MUSA, earnings are highly sensitive to fuel margins per gallon, which can compress quickly when wholesale gasoline prices fall or competition intensifies.

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 GRWG if you believe its drivers more; MUSA 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 GRWG and MUSA guides.

MUSA. MUSA traded around a market cap of ~$10.4 billion in mid-2026 at a P/E of roughly 20x, above its ~15x five-year median, reflecting strong recent fuel-margin-driven earnings. Revenue is very large relative to market cap because fuel is a low-margin, high-turnover business, so profit swings with cents-per-gallon margins rather than headline sales.

Headline figures (approximate, Jul 2026): GRWG shows revenue (ttm) Modest in absolute terms and below prior peak levels; roughly stabilizing after several years of decline as the company shifts channels., profitability Still generating GAAP net losses, though management targets improving gross margin and positive adjusted EBITDA. Sustained GAAP profitability is not yet established., margins Gross margin has been improving as proprietary-brand mix rises, but remains sensitive to product mix and cannabis-market pricing., balance sheet Relatively low debt with a cash cushion intended to fund the turnaround; the key watch item is cash burn versus progress to breakeven.; MUSA shows market cap ~$10.4 billion, q1 2026 net income ~$136 million (~$7.28 diluted EPS), q1 2026 revenue ~$4.82 billion (up ~21% YoY), p/e ratio ~20x (above its ~15x 5-year median).

GRWG and MUSA 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.
