GPI vs PAG: 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.

Reading it: GPI is the cheaper of the two on forward earnings, but cheaper is not the same as better. Pair the valuation with growth (how far the forward P/E sits below the trailing P/E) and risk (beta) before you decide.

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. GPI and PAG 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 GPI and PAG 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.

Group 1 Automotive, Inc. (NYSE: GPI) is one of the largest franchised automotive retailers in the world, selling and leasing new and used cars and light trucks, arranging financing, selling service and insurance contracts, and providing maintenance, repair, and collision services plus retail and wholesale parts. As of December 2025 the company operated a retail network spanning 17 U.S. states and 62 U.K. towns and cities, with roughly 145 U.S. dealerships and 109 U.K. dealerships. Its business splits across four revenue streams: new vehicles, used vehicles, parts and service (the highest-margin, most recession-resilient piece), and finance and insurance (F&I), which carries very high incremental margins because it monetizes financing and product attach on each sale.

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

• GPI drivers: Parts, service, and F&I durability; U.K. expansion and diversification.
• PAG drivers: Recurring service and parts; Penske Transportation Solutions stake.

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: GPI is a highly cyclical business exposed to new and used vehicle demand, which softens when interest rates are high, financing gets tighter, or consumer confidence weakens. For PAG, vehicle retail is cyclical and sensitive to interest rates, consumer confidence, and vehicle affordability, so new-unit volumes can fall in downturns (same-store new units declined about 5% in Q1 2026).

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 GPI if you believe its drivers more; PAG 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 GPI and PAG guides.

GPI. GPI trades at roughly 8x earnings, a discount of about 40% to the broader retail industry median and in line with the low-multiple auto-retail peer group. The single-digit multiple reflects the cyclical, capital-intensive nature of the dealership model and market caution about where vehicle margins settle as post-pandemic pricing normalizes. Aggressive buybacks support per-share metrics even as total net income declined year over year in 2025.

PAG. PAG carries a market capitalization of roughly $11 billion against annual revenue near $31.8 billion, reflecting the thin-margin, high-volume nature of vehicle retail. Adjusted earnings per share of about $3.05 in Q1 2026 beat consensus but declined roughly 15% year over year as margins normalized from prior highs. The stock is often viewed through a dividend and cash-flow lens given its long streak of payout increases.

Headline figures (approximate, July 2026): GPI shows revenue (2025) ~$22.6B, q1 2026 revenue ~$5.4B, net income (2025) ~$324M, market cap ~$4.1B; PAG shows revenue (2025) ~$31.8B, q1 2026 revenue ~$7.9B, q1 2026 net income ~$235M, q1 2026 adjusted eps ~$3.05.

GPI and PAG 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.
