Block: The AI Layoffs Undeniably Made It More Efficient — Now Growth Has to Prove It

Jack Dorsey fired 4,000 people — about 40% of Block's staff — in February and blamed artificial intelligence. The CFO, Amrita Ahuja, has spent the months since insisting the cuts didn't hollow out the company that runs Square and Cash App; they made it a "far more efficient" one. It's the kind of claim investors hear so often from management that they tune it out. What's unusual here is that it has started producing numbers a skeptic can actually check.

The strongest one is gross profit per employee. Ahuja has watched it rise from roughly $500,000 in 2019 to about $1 million in 2025, and she told reporters the company is on track to roughly double that — toward $2 million — during 2026. The fastest way to see why that's plausible, not just asserted, is to divide the year's math yourself: Block now guides to about $12.5 billion in gross profit for 2026, and it is running the business with under 6,000 people. $12.5 billion divided by 6,000 is a bit over $2 million a head. The company cut payroll by roughly 40% while still planning to grow gross profit by about 20%. That arithmetic is the whole story in miniature.

The formula is working in the operating statements too. Adjusted operating income hit a record 25% margin in the first quarter, then a record 27% in the second, with adjusted operating income up 57% year over year and gross profit still growing 25%. Management responded to the two quarters by raising full-year guidance a second time: gross profit of $12.51 billion, up 21%, and adjusted operating income of $3.47 billion at a 28% margin, up 67%. The quarter also beat on revenue ($6.62 billion), with Square's payment volume growing at its fastest pace in three years and Cash App gross profit up 31%.

The part the headline leaves out

None of that is at issue after two clean beat-and-raise quarters. The question for anyone deciding whether Block is worth owning at $79 is how much of this "efficiency" is real operating leverage and how much is arithmetic dressed up as a transformation.

Start with the per-employee number, because it flatters the most. Cutting four in ten workers while gross profit grows 20% doubles the per-employee figure almost mechanically — the denominator shrank by 40% and the numerator grew by a fifth. That is a real efficiency gain, but it says more about the size of the layoff than it does about AI. The CFO's argument that AI is the engine rests on softer evidence: a roughly 40% improvement in developer productivity since September, and one risk-underwriting model that previously took a full quarter to build being finished "in a fraction of the time." Plausible, and exactly the kind of claim that needs to keep showing up in shipped products rather than anecdotes.

The margin is the other number to look at carefully. A 27% adjusted operating income margin is a record for Block, but it is an adjusted number — it excludes stock-based compensation. On a plain GAAP basis, Block's operating margin is about 5%. For a company that has long paid its engineers and executives heavily in equity, that gap is not a footnote; it's the difference between "wildly efficient" and "still reinvesting to pay its people." The CEO's own framing gestures at this — he said the cuts were also correcting for pandemic-era over-hiring, which is a margin thesis wearing an AI costume.

The valuation has already moved

This matters because the easy money in the story appears spent. Block's shares jumped about 20% the day the layoffs were announced and are up roughly 20% year to date, though they've pulled back about 9% from the $86.92 high. The stock trades at a forward price-to-earnings ratio near 33 on consensus estimates. That is not a bargain sitting around waiting to be discovered; it's a price that has already banked the efficiency thesis and then some.

There is one genuinely attractive counterweight. Block is producing free cash flow of close to $3.9 billion a year — up more than 200% from a year earlier — against a market capitalization near $47.6 billion, with a net cash balance sheet and about $6.4 billion of cash on hand. At that level of cash generation, the shares are not absurdly stretched the way they'd be on the headline multiple alone. But free cash flow for a company that holds bitcoin skips around quarter to quarter, and it's the growth rate — not the margin — that will determine whether today's price is sensible.

What actually breaks the story

The falsifiable test for the whole bet is the next two to four quarters, and it comes down to one question: can gross profit keep growing in the low-to-mid-20s percent range now that the obvious cost savings are behind it?

The reason that's the live question is that the CFO has said there's no hard cap on hiring and Block expects to keep adding sales and AI-engineering staff. The moment headcount stops shrinking and starts growing again, the per-employee calculus that made this story so compelling starts to reverse — unless revenue decelerates even faster, which would be worse. Offset that against the bull case: an under-6,000-person company that still grows gross profit 20%-plus with 59 million monthly Cash App transacting users looks genuinely leveraged for the first time in its history.

So this is not a "the layoffs were fake" story, and not a "buy the momentum" story either. Block's CFO has real, checkable numbers behind a claim that usually has none, and the company has delivered two quarters proving she wasn't bluffing. But the durable question — whether a 28% adjusted operating margin and a per-employee figure that roughly doubled hold up as the company starts to hire again — is the one the market still hasn't priced in, for better or worse. The stock has rewarded those who believed management; it now needs the growth to prove it wasn't buying a one-time margin bump.
