RUSHA vs RUSHB: Which Is the Better Buy in 2026?

Same yardstick, side by side (as of September 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. RUSHA and RUSHB 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 RUSHA and RUSHB 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.

Rush Enterprises operates Rush Truck Centers, the largest network of commercial vehicle dealerships in North America, with more than 125 locations across the United States and Canada. It sells new and used heavy-duty and medium-duty trucks built by Peterbilt, International, Hino, Isuzu, Ford, IC Bus and Blue Bird, and layers on aftermarket parts, service, collision repair, financing, leasing, rental and insurance products, positioning each location as a one-stop hub for commercial fleet customers. The Class A shares (RUSHA) carry one-twentieth of a vote versus the Class B shares (RUSHB), but RUSHA is the far more liquid and widely held class.

Rush Enterprises, Inc. (NASDAQ: RUSHA and RUSHB) runs Rush Truck Centers, the largest network of medium- and heavy-duty commercial truck dealerships in North America, with roughly 167 dealership locations plus about 61 leasing locations across 24 U.S. states and Ontario, Canada. It sells new and used trucks from brands including Peterbilt, International, Ford, Hino, Isuzu, Dennis Eagle, and Blue Arc, and, importantly, earns a large and steadier share of profit from aftermarket parts, service, and collision repair, plus truck leasing and rental, financing, and insurance. The aftermarket and service side of the business is the ballast that makes Rush less cyclical than a pure new-truck seller, because trucks on the road still need parts and maintenance even when new-vehicle demand softens.

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

• RUSHA drivers: Aftermarket parts and service as a stabilizer; Freight cycle and new-truck demand recovery.
• RUSHB drivers: Aftermarket parts and service as a cushion; Dealership network consolidation and acquisitions.

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: Rush is deeply cyclical, so a prolonged freight recession or high interest rates can depress new-truck demand and used-truck values for extended stretches. For RUSHB, the core risk is cyclicality: new commercial-truck sales rise and fall sharply with freight rates, fleet profitability, interest rates, and the broader industrial economy, and truck volumes softened in early 2026.

Pick RUSHA if you believe its drivers more; RUSHB 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 RUSHA and RUSHB guides.

RUSHA. Rush trades as a cyclical industrial retailer, typically valued in the low-to-mid teens on earnings rather than as a growth stock. Revenue softened in early 2026 on weaker new and used truck sales, but improving gross margin and resilient aftermarket revenue kept earnings roughly flat year over year. Figures are approximate and drawn from the most recent quarterly report; check the latest filing for exact numbers.

RUSHB. Rush Enterprises earns lower margins on truck sales but steadier, higher-margin income from aftermarket parts, service, and leasing, so revenue mix matters as much as the top line. In the first quarter of 2026, total revenue fell to about $1.68 billion as new-truck volumes softened, yet net income and EPS rose year over year, showing that the parts-and-service and leasing businesses cushioned the cyclical dip in vehicle sales. Because RUSHA and RUSHB share identical economics, valuation multiples such as the price-to-earnings ratio (roughly the low twenties in mid-2026) apply to the same underlying earnings for both share classes.

Headline figures (approximate, July 2026): RUSHA shows revenue (ttm) ~$7.5 billion, q1 2026 revenue ~$1.68 billion (down ~9% YoY), q1 2026 net income ~$61.5 million (~$0.77 per diluted share), market cap ~$4.3 billion; RUSHB shows revenue (ttm) ~$7.8 billion, q1 2026 revenue ~$1.68 billion (down from ~$1.85B a year earlier), q1 2026 net income ~$61.5 million, q1 2026 diluted eps ~$0.77 (up from ~$0.73).

RUSHA and RUSHB 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.
