SEZL vs SLM: Which Is the Better Buy in 2026?

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.

Reading it: SLM 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. SEZL and SLM 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 SEZL and SLM 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.

Sezzle Inc. is a technology-enabled payments company operating mainly in the United States and Canada. Its platform lets shoppers split purchases into interest-free or low-cost installments at the point of sale (Pay-in-Four, Pay-in-Five, and Pay-in-Two options), while merchants pay Sezzle a fee for the added conversion and basket size. The company also earns from consumer subscriptions (Sezzle Premium and Anywhere), late and account fees, and interchange, and it reports both positive and negative payment activity to credit bureaus, a differentiator from many BNPL peers.

SLM Corporation, known as Sallie Mae, is a consumer bank built around private education loans. It originates and holds Private Education Loans for students and families to cover the gap between college costs and federal aid and scholarships, and it funds those loans primarily through retail deposits at Sallie Mae Bank. It is the dominant player in US private student lending, holding roughly a 64 percent share of the market and originating about $7.4 billion of loans in 2025. Its business model leans on a wide net interest margin (around 5.3 percent in early 2026), disciplined underwriting with high cosigner rates, and a heavy program of loan sales and share buybacks to return capital.

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

• SEZL drivers: Subscriber and frequency growth; Profitable, self-funded scaling.
• SLM drivers: Dominant, high-margin niche lender; Capital return through buybacks and loan sales.

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: Sezzle lends to consumers, so a weaker economy or rising delinquencies could push credit losses back toward the 3 to 4 percent of GMV range and compress margins quickly; the step down in quarterly net income from Q1 to Q2 2026 shows how sensitive earnings can be. For SLM, sLM's fortunes are tied to consumer credit, so a weaker job market for graduates could push charge-offs and provisions higher and compress earnings.

Pick SEZL if you believe its drivers more; SLM 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 SEZL and SLM guides.

SEZL. Sezzle is profitable and growing revenue around 50 percent, which is unusual among BNPL pure-plays. After a roughly 27 percent pullback over the last three months, the shares trade near 29 times trailing and 20 times forward earnings, a lower multiple than earlier in 2026 but one that still assumes Sezzle keeps growing volume while holding credit losses low.

SLM. At about 6 times trailing and forward earnings, SLM trades like a credit-sensitive specialty lender the market does not fully trust, even with a profit margin above 40% and a modest payout. The second-quarter miss and a 19% year-to-date decline have pulled the multiple lower, while 11 covering analysts carry a mean target near $28. Figures are approximate and as of October 16, 2026, ahead of third-quarter results on October 22.

Headline figures (approximate, October 2026): SEZL shows revenue (ttm) ~$532M (Q2 2026 up ~52% YoY), revenue (q2 2026) ~$149.7M, net income (ttm) ~$161M (~30% margin), diluted eps (q2 2026) $1.13 (vs ~$1.01 est.); SLM shows market cap ~$4.2B (at ~$22.17, Oct 16, 2026), revenue (ttm) ~$1.69B; latest quarter growth ~8% yoy, net income (ttm) ~$721M; profit margin ~44%, eps (trailing / forward) ~$3.59 / ~$3.37.

SEZL and SLM 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.
