Klarna vs. Sezzle: Buy Now, Pay Later's Two Kinds of Cheap

Klarna vs. Sezzle: Buy Now, Pay Later's Two Kinds of Cheap

Same bell, same clock, one question: which is the better cheap way to own buy-now-pay-later — Klarna (NYSE: KLAR), the global payments network at roughly 1.3x forecast revenue, or Sezzle (Nasdaq: SEZL), the US specialist at roughly 23x earnings? Both stocks just lost roughly a quarter of their value in the days right after reporting strong quarters. The market disagreed with the companies about the future; this race is the honest way to find out which side is right.

The Card

Frozen at the close on Friday, August 21, 2026: KLAR at $14.33, SEZL at $119.11. Both enter at 100 paper points. The finish line is August 21, 2027 — one year on. The score is total return, which for now means price change only: neither company pays a dividend. No substitutions and no rebalancing; the two contestants stay frozen for the full year. Editorial odds, set here at the bell and never moved afterward: Sezzle a 55/45 favorite. These are a confidence device, not a sportsbook line, and every stake on this card is hypothetical paper.

The next checkpoints are the third-quarter reports, which land within a couple of weeks of each other in the fall, and then the fourth-quarter prints in early 2027. If a contestant is acquired, delisted, or fails, that leg marks to its last tradable price and the match settles in cash at that observation — no replacement, no rerun. A stock split adjusts the 100-point basis with no value change (Sezzle already did a six-for-one in the spring of 2025). If either company restates a result, both sides are recalculated under the same corrected rule, with a dated entry in the ledger.

Round 1: Two winners, two craters

Start with the prints, because without them the crashes look like panics over nothing.

Klarna reported on August 18. Second-quarter GMV of $36.6 billion (+18%), revenue of $1.042 billion (+27%), transaction margin dollars of $446 million (+42%), adjusted operating income of $91 million, net income of $9 million against the $17.4 million loss analysts modeled, and revenue $46 million ahead of estimates. The stock fell 22% to $15.06. The cause: management cut its full-year revenue outlook to $4.08–4.16 billion from above $4.34 billion, citing roughly $600 million of currency translation drag and a "more measured view" of Germany, its largest market, and guided the third quarter to $940–980 million against Street estimates near $1.11 billion. On the same call it disclosed that its CFO of six years and CMO of nine years are leaving in early 2027.

Sezzle reported on August 6. Record revenue of $149.7 million (+51.7%), GMV of $1.3 billion (+37.9%), net income of $40.8 million (+47.7%), and a third raise of the year to 2026 guidance — adjusted net income to $185.0 million, adjusted EPS to $5.25, revenue growth to 35%. After hours the stock fell 27.19% to $129.99 from a regular-session close of $178.53, because the guide says growth slows to about 30% in the second half and because the stock had already gained 144% year-to-date. It has drifted lower since.

Read the two reactions together and the pattern is identical from opposite directions: the current quarter was fine, the forward narrative was the fight, and the market judged the forward narrative the loser. That shared moment is why this matchup starts now.

Round 2: Same credit pool, different machines

Before the odds, the fair-opponent test. Both of these make almost all their money by lending short, automatic credit at checkout. GMV is the dollar volume of purchases routed through the app; revenue is the take-rate the lender keeps off that volume. Klarna collects about 2.8 cents per GMV dollar (its guided implied take rate for the year is 2.84–2.85%); Sezzle collected 11.7 cents in the second quarter, up from 10.6% a year earlier. The difference matters, but it is not magic — Klarna also moves roughly thirty times the volume, with 120 million active consumers and $36.6 billion in quarterly GMV against Sezzle's 3.16 million consumers and $1.28 billion.

The structural disagreement is where value is created. Klarna is a licensed bank that funds about 90% of its lending from low-cost consumer deposits; it is betting that a global network — 1.2 million merchants and 2 million paying subscribers, a card with 6.5 million active users, an expanding US business growing 27% — can monetize engagement the way a platform should. Sezzle is an asset-light, single-country specialist that funds a narrow, small-ticket book through warehouse lines and securitizations, and bets that running unit economics on a manageable portfolio beats owning a giant one. They answer the same economic question — who earns the installment-credit profit pool — with opposite answers. (The obvious third name, Affirm, is the one everyone already watches; the point of this duel is to test the two "cheap" ones.)

Round 3: The meaning of "cheap" is the handicap

Here is the card within the card, at the August 21 prices:

	Klarna	Sezzle
Market cap	≈ $5.4B	≈ $4.1B
Price / 2026 revenue	≈ 1.3x	≈ 6.7x
Price / earnings	no meaningful P/E — GAAP just broke even	≈ 23x 2026 adjusted EPS
Trailing profitability	FY25 net loss of $0.79 a share	FY25 net margin ≈ 30%

Both market caps are Friday's close times each company's latest disclosed share count — about 378 million shares for Klarna and 34,153,100 for Sezzle — so the multiples carry a visible denominator.

Klarna is cheap on revenue; Sezzle is cheap on earnings. That split is the whole match. The market prices Klarna at ~1.3x sales because at a guided 2026 adjusted operating margin of about 7%, those sales are only just producing profit — roughly 19x a thin adjusted operating income line, and still basically zero on reported GAAP net income ($9 million in the second quarter after $1 million in the first, following a full-year 2025 net loss). Sezzle looks expensive on sales but the market already pays for the profit the model demonstrably makes: a 39.3% operating margin in 2025, a 27.2% net margin last quarter, and an 88.9% return on equity over the trailing twelve months. Its forward multiple of ~23x on earnings growing 35% is a PEG near 0.7.

Neither looks expensive if you trust the business; the question is which denominator the market is wrong about. If Klarna's revenue converts to real per-share profit over the next year, 1.3x sales is a gift. If Sezzle's credit book cracks in a softer consumer environment, its cheap earnings were a price ahead of a loss.

The credit lens is worth one quick calculation, because it undercuts the lazy version of this debate. Klarna's provision for credit losses was 0.52% of GMV in the second quarter; Sezzle's was 2.4%. But each company's GMV dollar carries a very different revenue take. Divide the provision by each company's own take-rate — 2.8 cents for Klarna, 11.7 cents for Sezzle — and both hand over roughly one revenue dollar in five to credit losses. The subprime-looking provision ratio is mostly a take-rate artifact. What truly differs is how much gross margin sits on top: Klarna keeps 42.8% of revenue after its transaction costs; Sezzle kept 63.5% of revenue after the same layer, up 240 basis points in a year. Klarna's revenue is grosser; it carries more cost inside each dollar. That is the mechanism the race will referee.

Round 4: The mechanism board

Four variables carry the match. They interpret the score; they do not override it.

Profit conversion. Sezzle is already all the way through the funnel: 63.5% of revenue after transaction costs, a 39.3% operating margin, and net income in 2025 that grew 69.5% to $133.1 million on revenue of $450.3 million. Klarna is mid-transition: transaction margins are improving fast (+4.5 points to 42.8% of revenue), but adjusted operating income this year is guided to only 6.9–7.2% of revenue, and GAAP net income is a rounding error. The watch item is whether Klarna's conversion closes the gap without re-breaking.

Credit trajectory. Both books are behaving well into 2026 — Klarna's provisions fell to 0.52% of GMV from 0.56%, Sezzle's 2.4% is within its full-year target of 2.5–3.0%. A consumer slowdown is the shared risk, and it is priced to hurt the lender whose customers are primed for rejection. Sezzle's small-ticket, mainstream shoppers are the more rate-sensitive population; Klarna's Germans are the macro hinge.

Growth quality. Klarna's revenue growth decelerated from +44% in Q1 to +27% in Q2, with GMV growth of 18% and US GMV up 27%. Sezzle is growing faster on every line — subscribers up 76.4% to 854,000, purchase frequency at a company-high 7.2x — and is deliberately steering second-half growth down to about 30%. Slowing from 52% to 30% is a guidance story, not a breakdown story; the market chose to read it as the former.

Capital and funding. Klarna funds ~90% from deposits and supports US capacity with a $2 billion forward-flow facility; that is structurally cheap if deposits stay sticky. Sezzle has no deposit moat but needs almost no equity: a new $300 million credit facility with Mesirow lowered its funding cost, net interest expense fell 12 basis points year over year, liquidity is above $205 million, and with the book largely funded off-balance-sheet it posts an 88.9% return on equity. The counterweight is that Sezzle's whole margin narrative depends on securitization markets staying open.

Round 5: Each side's best short

A contest that only argues for one fighter is a commercial, so here is the strongest case against each.

The case against Klarna: growth is visibly decelerating (44% → 27% in one quarter), the guided third quarter is a miss against the Street, Germany — its largest market — is the reason, and it is simultaneously replacing two of its most senior executives. A stock that has already fallen from a $40 IPO price and a $57.20 high to $14.33 can keep falling if guidance keeps resetting. Paying ~19x a non-GAAP profit line whose GAAP counterpart is near zero is not self-evidently "cheap."

The case against Sezzle: it ran 144% before the print, so the bar was a whisper number higher than the guidance it actually gave; a 6.78 beta and a 27% post-earnings drop show how violently expectations can revert. It is a one-country book of small-ticket credit, marketing spend more than doubled in the quarter, and the credit targets are guidance, not law. If arrears drift above 3.0% of GMV in a cooling consumer, the multiple compresses even if the margin math holds.

Both sides also carry the category cloud that attaches to BNPL as a product — regulators treating installment credit like credit cards, consumer-credit headlines, and a sceptical premium on the whole group. That cloud is why both are priced where they are.

Round 6: The odds, the protocol, and the exit tree

Why 55/45 Sezzle? Because its "cheap" is a multiple on earnings the model already makes, with a return on equity that proves capital efficiency, and the bear case requires a credit cycle event that has not arrived. Klarna's "cheap" is a multiple on revenue whose conversion to profit is still being demonstrated, inside a window that now includes two C-suite departures and a second guidance cut inside a year. Favoritism is fragile, not settled: if Klarna posts a quarter where GAAP net income actually starts compounding, its upside surprise is the larger of the two, because the market is currently paying almost nothing for its 1.3x-sales profit turn. And if credit wobbles, Sezzle's favorite status evaporates first.

The protocol is written and it does not improvise. Total return is the score, including any dividend initiated before the finish. No substitutions of any kind. Mergers, delistings, suspensions, or bankruptcy are marked to the last official tradable close and settled in cash on that observation date. Splits are mechanical, not economic. Restatements recalculate both legs from the same corrected inputs with a dated ledger entry. Updates run on the earnings calendar only — every quarter, plus any material corporate action — never more often because the favorite is losing, never less often because the result is awkward.

Next checkpoint

At the bell it is 100–100, no leader, zero spread. Sezzle owns the mechanism edge on profitability and return on capital; Klarna owns the upside-amplitude edge if its profit turn arrives. The score over the next four quarters will not tell you whether BNPL is cheap — it will tell you which denominator the market was right to discount. Watch the third-quarter prints this fall for Klarna's guided ~7% adjusted margin showing up in GAAP net income, and for Sezzle's 30% second-half growth holding without its credit provisions drifting through the top of target. The one line to carry out of the arena: a low multiple is only as real as the denominator the company actually earns on, and the next four quarters are the experiment that names the real one.
