Block Raised Guidance, Expanded Margins, and the Stock Fell — the Disconnect That Matters

Block just delivered the kind of quarter that should force Wall Street to rewrite its script. Revenue of $6.62 billion beat estimates, adjusted EPS of $1.02 cleared consensus by a wide margin, gross profit grew 25% year over year, and the adjusted operating margin hit a record 27%. Management then raised full-year guidance across the board — including a 70% jump in adjusted EPS to $4.02 — and the stock closed down 1.2% the next day.

That is the disconnect. The market called it "profitable momentum" and moved on. The math says something sharper: Block is growing operating profit roughly twice as fast as gross profit, raised its guidance after the strongest operational quarter in years, and trades at a forward multiple that doesn't price in the acceleration it just proved.

Here is what actually matters.

1. The operating leverage is real, not a one-quarter accounting blip.

In Q1 2026, adjusted operating income grew 56% and adjusted EPS grew 52%, roughly double the 27% gross profit growth rate. That pattern continued in Q2 with operating income of $864 million at a record 27% margin. For a company the market has punished for years of GAAP losses, this is the inflection it needed to show. The spread between top-line growth and bottom-line growth isn't a fluke — it's structural leverage from a reorganized cost base and faster product development. CFO Amrita Ahuja told analysts on the call that the new outlook included "no significant conservatism," pointing to strong July trends in both Square payment volume and Cash App inflows.

2. Square finally shows U.S. acceleration after quarters of stagnation.

Square gross payment volume grew 13% to $72.8 billion. The number that stands out is U.S. GPV growth of approximately 10% — the strongest rate since Q2 2023. Food-and-beverage volume rose 20%. Mid-market sellers were the fastest-growing segment. Self-onboarded new volume grew at its fastest pace since Q2 2021. The market spent most of 2025 focused on six consecutive quarters of revenue misses and assumed the Square flywheel was broken. The data says otherwise: self-onboarding is reaccelerating, the mid-market is expanding, and the restaurant channel — historically the backbone of Square's growth — is back.

3. Cash App gross profit grew 31%, driven by monetization, not just user growth.

Cash App monthly transacting actives grew a modest 3% to 59 million. The growth engine isn't new users — it's revenue per user. Inflows per active grew 9%. Commerce volume rose 17% to $56.5 billion. Consumer lending (Borrow) originations jumped 59% to $18.9 billion. Management noted that Borrow loss rates remain healthy and loss growth should moderate. The Cash App profit machine is deepening its existing user base rather than chasing marginal new ones. That's the healthier path — monetization expansion carries less execution risk than user acquisition, and the margins on lending are substantially higher than payment processing.

4. AI-driven product velocity is the operational backbone, not marketing vapor.

Co-founder Jack Dorsey said the intelligence-focused reorganization is on track. The metric that matters: code changes per engineer rose 150% since the start of 2026. Square shipped 130 features in the first half of 2026 — more than triple the prior-year pace. This isn't a press-release version of AI. It's a measurable productivity multiplier feeding directly into the operating leverage story. If engineers can ship three times the output at the same cost, the cost-to-income ratio compresses. That's the mechanism behind the 27% operating margin.

5. The raised guidance and the 2028 road map.

Block raised its full-year 2026 adjusted EPS to $4.02, up from $3.85 after the Q1 beat and up 70% year over year. Full-year gross profit guidance moved to $12.51 billion (up 21%), and adjusted operating income is projected at $3.47 billion with a 28% margin.

Stepping further out, at the November 2025 Investor Day, management laid out a three-year path: gross profit of approximately $15.8 billion by 2028 growing at a mid-teens CAGR, adjusted operating income climbing about 30% annually to over $4.6 billion, and adjusted EPS reaching $5.50 by 2028. Block also expanded its share repurchase program by $5 billion, adding to $1.1 billion in remaining authorization. The buyback program acts as a floor on per-share metrics even if growth slows.

The valuation closer.

Block's market capitalization sits around $40.6 billion. At the raised 2026 adjusted EPS of $4.02, the stock trades at roughly 20 times this year's earnings. On the 2028 adjusted EPS target of $5.50, it trades at approximately 15 times. That is below the projected 30% annual operating income growth rate.

A fintech company growing operating income in the low-30s range, running a 27% adjusted operating margin, with a reaccelerating Square business and a Cash App that's monetizing deeper into its existing user base — trading at 15 times the earnings it projects two years from now — doesn't fit the "profitable momentum" label. It fits the "the market still hasn't caught up" label.

The risk.

Consumer lending exposure is the variable that could break the thesis. Borrow originations grew 59% to $18.9 billion in Q2, and lending capital is expected to exceed $4 billion by 2028 — roughly 25% of gross profit. If the macro turns and loss rates spike, the operating leverage story compresses fast. Management says loss rates are healthy and moderation is coming. That's the claim to watch in Q3 and Q4.

The setup.

The stock dropped the day after earnings. The guidance was raised. The margin expanded to a record. The growth accelerated. The forward multiple on 2028 targets is below the growth rate. If Borrow loss rates hold and the U.S. Square acceleration continues, the gap between what the stock reflects and what the math supports narrows. At 15 times 2028 adjusted EPS, Block is trading like a company that's just finding profitability — not one that's accelerating into it.
