Affirm Q4 earnings blew past Wall Street on the headline metric by a margin that should make anyone suspicious. Earnings per share came in at $4.62 against a consensus of $0.85, a surprise of roughly 443%. Revenue landed at $1.17 billion versus a forecast near $1.11 billion. The stock closed the regular session at $77.49 and then jumped 8.34% after hours to $83.95.

What the Affirm Q4 Earnings Print Really Shows

Set the EPS figure aside and the operating quarter inside the Affirm Q4 earnings stands on its own. Revenue grew 33%. Gross merchandise volume reached $14.1 billion, up 36% and comfortably ahead of the $13.39 billion analysts expected, marking an eleventh straight quarter of GMV growth above 30%. Revenue less transaction costs rose 39% to $589 million, and funding costs fell 103 basis points to 5.8%.

Credit held up across the quarter as well. The 30-day delinquency rate on monthly installment loans, excluding Peloton and Pay in X, improved to 2.5% from the 2.7% to 2.8% band of the prior three quarters. Active consumers grew 21% to 27.8 million, transactions per consumer rose 20% to 7.0, and the Affirm Card added actives at a 125% clip to reach 5.2 million.

The Tax Release Behind the Affirm Q4 Earnings Beat

Now the EPS number, which is a different animal. Reported net income landed near $1.6 billion, wildly out of proportion to a company whose GAAP operating income for the same quarter was $147 million. That gap does not come from operations. It came from the release of a valuation allowance on most of Affirm’s domestic deferred tax assets, the one-time event that occurs when a company with years of accumulated losses becomes confident enough in future profits to recognize their tax benefit all at once.

Here is what makes the Affirm Q4 earnings coverage frustrating. This was not a surprise. Affirm told investors months ago, in its own quarterly shareholder letter, that if the earnings trajectory held there might be enough positive evidence to release a significant portion of the U.S. deferred tax valuation allowance by the end of fiscal 2026. The company telegraphed it, then delivered it on schedule. Anyone reading the filings knew the arithmetic was coming.

Management drew the same line on the call, describing the quarter as its most profitable ever even excluding the tax allowance release. That framing came from Affirm rather than from analysts cleaning up after it, which is worth noting when assessing how the Affirm Q4 earnings were presented.

Why the Affirm Q4 Earnings Growth Story Is Real Too

None of this makes the beat fake. Auditors do not permit a release of this size unless future profitability looks probable, so the accounting decision is itself a statement about where the lending book is headed. But the $4.62 belongs in a footnote when the question is whether the underlying business improved in three months.

The honest reading is that the Affirm Q4 earnings contained two separate good stories that got collapsed into one misleading number. Adjusted operating income hit $353 million at a 30% margin, while GAAP operating margin reached 12.6%, six points better than a year earlier. Full-year GMV came in at $50.2 billion against $36.7 billion the year before.

Guidance alongside the Affirm Q4 earnings reinforced it. For fiscal 2027 Affirm expects GMV above $64 billion and adjusted operating margin above 30.5%, with first-quarter revenue of $1.19 to $1.22 billion. Management also flagged how much runway remains, noting Affirm appears on only 80 of the top 250 e-commerce sites and roughly 10% of e-commerce merchants overall.

How to Read the Affirm Q4 Earnings Reaction

Investors reaching for the $4.62 figure will overstate how much better this business got in a quarter. The after-hours move suggested the market did some of that on Thursday evening.

The Affirm Q4 earnings follow-through tells a calmer story. Shares rose roughly 7% in Friday trading, holding most of the initial pop rather than giving it back, which suggests analysts separated the tax event from the operating results without much drama. That is the more useful test, and it broadly cleared.

So the Affirm Q4 earnings verdict splits. The headline profit number is an accounting event that will not repeat, and treating it as a growth signal is a mistake. The quarter underneath it was strong on volume, funding economics and credit quality, and stronger than the guidance range implied. Watch whether the fiscal 2027 GMV target survives contact with a competitive pay-later market, because that number, not this one, is what the multiple rests on. The wider fintech credit cycle will decide how much of it lands.
