Block Q1 2026 slides: 27% gross profit growth drives raised guidance

Block delivered a strong Q1 2026 with gross profit up 27% year over year to $2.91B, adjusted operating income up 56% to $728M, and adjusted diluted EPS of $0.85, while raising full-year guidance. Cash App was the main growth driver, with gross profit up 38% to $1.91B and consumer lending originations surging 82% to $17.6B; Square gross profit rose 9% to $982M. The company also reported $852M of restructuring charges and a $173M bitcoin remeasurement loss, but the market appears focused on the acceleration in profitability and higher outlook.

Analysis

The market is likely underpricing how much of this quarter is mix-shift rather than just cyclical lift. The lending acceleration in Cash App is the key second-order driver: if originations continue compounding at this pace, the product mix pushes gross profit quality higher while also raising attach rates across payments, card, and direct deposit. That creates a flywheel where more user cash flow data improves underwriting, which in turn expands lending capacity without needing equivalent increases in acquisition spend.

The biggest medium-term risk is that the market extrapolates current loan growth as purely positive when it may be the most cyclical and regulation-sensitive piece of the story. Consumer lending is the segment most vulnerable to delinquency normalization, funding cost pressure, and any tightening in underwriting standards; those issues usually show up with a lag of 2-4 quarters, not in the headline quarter. If credit performance deteriorates even modestly, the current multiple expansion thesis can compress quickly because the bull case depends on sustained confidence in operating leverage.

For Square, the more important signal is not U.S. seller growth but the international GPV inflection. That suggests Block’s merchant stack may be reaching a point where product-market fit is broadening outside the core domestic SMB base, which is a longer-duration earnings stream than Cash App lending. The flip side is that hardware drag and lower take rates can mask this progress in reported results, so the market may continue to underestimate the durability of Square’s contribution until international mix is materially larger.

Consensus likely sees this as a clean “quality growth” print, but the better read is that Block is becoming a leveraged call option on consumer monetization with a sturdier merchant annuity underneath. The multiple should stay supported as long as Rule of 40 remains above 45%, but the stock will become increasingly sensitive to any sign that lending growth is slowing faster than the rest of the ecosystem. In that sense, the next catalyst is not the next earnings beat; it is whether management can prove that accelerated lending is translating into durable retention and cross-sell rather than front-loaded risk-taking.

Key Decisions for Investors

• Long SQ into the next 1-2 quarters on strength, but size as a growth-with-credit-risk position; upside remains if Rule of 40 stays >45%, while downside accelerates if lending growth decelerates or delinquency commentary turns cautious.
• Buy SQ call spreads 3-6 months out rather than stock if positioning for continued multiple re-rating; the thesis is strong near-term execution with limited duration risk, but credit sensitivity argues for defined downside.
• Hedge SQ long exposure with a short basket of consumer-finance/lending-sensitive fintechs over the next earnings cycle if you want to isolate Block’s superior ecosystem quality from sector beta.
• Monitor SQ on the next two quarters for lending loss provisions and deposit inflow growth; if inflows per active stalls while originations keep rising, reduce exposure because the underwriting flywheel may be weakening.
• Add on pullbacks only if the market overreacts to GAAP noise from restructuring charges; the cleaner entry is after any post-earnings digestion when investors can separate one-time costs from the underlying margin inflection.
