A late write-up. Klarna reported the June quarter before the US open on 18 August 2026; this piece is dated 2 September and reads the print, the outlook table and the call with two weeks of hindsight rather than on the day.
The quarter itself was the best Klarna has filed as a public company, and almost nobody cared. What moved the stock was one line of guidance: September-quarter revenue of $940–980 million, against the $1,042 million just reported. A sequential decline, guided, from a company that had grown revenue 26.6% year on year in the quarter it was announcing.
Klarna's own outlook table says that decline is not what it looks like. The table prints revenue as a percent of volume twice — 2.74–2.75% as reported, and 2.84–2.85% "ex. move to fair value". That ten-basis-point wedge is worth about $150 million of full-year revenue, and because the accounting change starts in the second half, every dollar of it lands in the two quarters the guide covers. The wedge is Klarna's disclosure. The consequences below are our arithmetic on it.
When Klarna joined coverage here on 29 August we said that guided sequential decline is why the stock sits 64% below its IPO price. It is — the market read the printed line, and the printed line is what the market prices. What follows does not undo that. It says the printed line and the business are not the same object this half, and Klarna's own table is where the difference is written down.
The full-year cut, on the row Klarna publishes beside the headline one
In May, Klarna guided 2026 to more than $155.0 billion of volume and more than $4.34 billion of revenue, at more than 2.80% of volume. In August it guided $149.0–151.0 billion and $4.08–4.16 billion, at 2.74–2.75%.
Read as printed, that is a 4.1% to 6.0% cut to full-year revenue. Read on Klarna's own ex-fair-value ratio — 2.84–2.85% of the same reduced volume, or $4.23–4.30 billion — it is a cut of 0.8% to 2.5%. Both numbers describe the same guidance. One of them is mostly about German consumers; the other is mostly about where a receivable sits on the balance sheet.
The same wedge reframes the sequential decline. First-half revenue of $2,054 million is on the old basis, so the guide implies $2,026–2,106 million for the second half as reported. Add the fair-value effect back and the second half is about $2,178–2,250 million on the basis the June quarter was reported on — an average of $1,089–1,125 million a quarter against the $1,042 million that supposedly cannot be repeated. Year on year, the second half goes from +2.1% to +6.1% as printed to roughly +10% to +13% like for like.
Two honest caveats travel with that. Klarna does not split the effect between the September and December quarters, and December carries more volume, so the September quarter alone may still print below June on either basis. And both ratios are rounded to two decimals, so the $150 million is really about $135–165 million. Neither caveat changes the direction: the headline sequential decline is substantially a change in what gets counted as revenue.
Our own Klarna model, published on 29 August, re-bases second-half revenue for this change by a factor of 0.9323. Working the guidance table from the other end gives 0.9304 to 0.9362. Two independent routes to the same number is the strongest evidence available that the wedge is real and roughly this size.
The metric that really was guided down
Klarna's own headline measure is transaction margin dollars — revenue less servicing costs, credit provisions and funding costs. The fair-value change flatters that line rather than depressing it, so there is no basis excuse available here.
September transaction margin is guided to $340–360 million against $446 million delivered in June, a 19% to 24% sequential fall. Some of that is seasonal — the same step a year earlier was −11% — but the growth rate is the tell. Transaction margin grew 42% in the first half; the full-year guide of $1.62–1.65 billion leaves $785–815 million for the second, against $652 million a year earlier, or +20% to +25%. Niclas Neglén put the same figure on the call in one sentence:
we're looking at around about 23% year-over-year growth on TMD in the second half, if you take the midpoint of our guide, that is compared to 42% in the first half of '26
Halving the growth rate of the metric a company says it optimises for is a larger disclosure than a top line that changed its accounting.
Underneath it, the profit shape moved rather than shrank. Full-year adjusted operating income guidance barely moved — more than $299 million became $280–300 million — but September is guided to $5–15 million against the $91 million just delivered. With $159 million already booked in the first half, that leaves $116–126 million for the December quarter alone: about 41% of the year in one quarter. Klarna has never disclosed a December quarter of that size. It is the single most demanding number in the outlook table, and it is not the one the market reacted to.
What the call added
The release did not carry the reason for the volume cut, the extent of the accounting change, or the leadership news. The call carried all three.
Germany, and only Germany. Neglén: "what we saw towards the back end of 2Q was a softening in basically the consumer discretionary spend in Germany. Germany is our largest share of volume or our largest market from a volume perspective... And that's where we're playing out through the rest of the year, assuming that we're not seeing a recouping of that." He was explicit that the guide assumes no recovery, and equally explicit that it is not a European pattern: "we run in 26 markets... If you take the Nordics as an example, I mentioned before, we're getting double teen growth rates."
The fair-value change is bigger than "some Fair Financing". Neglén: "we've come to the point where basically all -- substantially all of our loans will be eligible to be sold in the second half of this year, and that's where we're making that fair value change." The line it flows into, "gain on sale of consumer receivables", was $69 million this quarter — 6.6% of revenue — against zero a year ago. Klarna is becoming an originate-to-sell lender, and the revenue ratio the market prices it on is the first casualty.
The US is closing the margin gap that the whole story rests on. US revenue grew 36.7% to $376 million and US transaction margin went from 14.2% to 23.4% of US revenue in twelve months, against a rest-of-world book at 53.8%. Neglén: "Transaction margin dollars as a percentage of revenue went from 14% to about 23%, and we're expecting to see growth in that through the quarters as well on a sequential basis." US Fair Financing volume grew 114%, against 82% for the group. The US is already 36% of group revenue on 22% of group volume.
And the CFO is leaving. Sebastian Siemiatkowski disclosed on the call, not in the release, that "in early '27, we will make two leadership transitions. Niclas Neglén, our CFO, after 6 years at Klarna... This is an early heads up, not a goodbye." The CMO hands over in the same window, and the CFO search is for a New York hire: "It's our largest market by revenue, not yet by volume." A CFO transition announced in the same hour as a guidance cut and an accounting-basis change is a lot of change to underwrite at once.
Against the model
The Klarna model was built on this print, so the quarter does not grade it — the quarter is its basis. What the model does supply is the price of the argument above.
Its base case projects $968.9 million of September revenue, inside the guided $940–980 million, and $4,086 million for the year, inside the guided $4.08–4.16 billion. It carries no operating leverage beyond what the transaction margin itself delivers and holds the disclosed 66.7% effective tax rate flat — two deliberate conservatisms, each worth roughly a doubling of the answer on its own. On those assumptions the base case is $4.45 a share against the $14.20 price of 29 August, the bull case $16.24, and management's own stated long-term model $21.01. Those are our assumptions and our arithmetic, not company forecasts.
The reading that follows is uncomfortable for both sides of this stock. At $14.20 the market is already paying for most of the bull case — the case in which the cost base converts and the tax rate normalises — in a name that just guided its own headline metric's growth rate down by half. The basis wedge this article is about makes the revenue line look worse than it is; it does nothing for the valuation.
What is coming
The September quarter reports on 17 November 2026. Three numbers settle what the August table left open: whether revenue lands inside $940–980 million and how much of the gap to June turns out to be the accounting change; whether transaction margin lands inside $340–360 million, which is the honest read on European demand; and whether adjusted operating income clears the $5–15 million floor without borrowing from December.
Then December has to produce $116–126 million of adjusted operating income to hold the full-year guide, on the seasonally largest volume quarter of the year. That is the number to write down now.
What we learned
- The guided sequential revenue decline is largely a change of basis. Klarna's own outlook table prints revenue as a percent of volume twice, 2.74–2.75% as reported and 2.84–2.85% excluding the move to fair value: about $150m of full-year revenue, all of it in the second half.
- On Klarna's own like-for-like row the full-year revenue cut is 1–2.5%, not 4–6%. More than $4.34bn became $4.08–4.16bn as printed, and $4.23–4.30bn on the ex-fair-value ratio published beside it.
- The metric Klarna says it optimises for is the one genuinely guided down. Transaction margin dollars of $340–360m for September against $446m delivered, and second-half growth of about 23% against 42% in the first half.
- Full-year adjusted operating income barely moved, and almost half of it now sits in December. More than $299m became $280–300m, but September is guided to $5–15m against $91m just delivered, leaving $116–126m for the December quarter.
- The US transaction margin closed nine points in a year. 23.4% of US revenue against 14.2%, on US revenue up 36.7% to $376m and US Fair Financing volume up 114% — against a rest-of-world book at 53.8%.
Klarna Group plc (NYSE: KLAR) reported the three months ended 30 June 2026 before the US open on 18 August 2026. Revenue, transaction margin dollars, adjusted operating income, the regional split, the gain-on-sale line and the full-year and September-quarter outlook table are the company's own, from the earnings release; the full figure set is on the Klarna Q2 2026 earnings page. Klarna reports under IFRS in US dollars and files no quarterly US filings, so the release is the only source for these figures. Quotations are from the earnings call held the same morning and sit on the call page; Klarna publishes no transcript of its own, so the wording is a third party's transcription checked against the release. Ours rather than the company's: the like-for-like revenue cut, the second-half and per-quarter figures implied by the outlook table, the implied December-quarter adjusted operating income, the re-basing factor, and every growth rate computed from disclosed figures. Consensus of a $0.07 loss per share is from Nasdaq/Zacks and the $993.39m revenue estimate is press-reported; neither is a series this site verifies. Fair values are from our model of 29 August 2026 against its $14.20 price on that date and are assumptions, not forecasts. Guidance is forward-looking.
