Marqeta at FT Partners FinTech Conference: growth broadens as block fades

Marqeta reported annualized platform volume above $450 billion, growing more than 30% year over year, while maintaining 2026 gross-profit growth guidance of 11%-12%; excluding roughly 6 percentage points of deal-renewal and Cash App pricing effects, underlying growth is expected in the mid-to-high teens. Block remains a significant concentration at 41% of net revenue, although non-Block customers are growing twice as fast; Cash App issuance moderation and a roughly 1bp Q2 take-rate decline remain key near-term headwinds. Management expects flat expenses over the next two quarters, with operating leverage, AI-driven engineering productivity, European expansion, value-added services and managed credit supporting longer-term margin expansion.

Analysis

MQ’s key valuation debate is shifting from volume growth to monetization durability. Contractual scale discounts, enterprise mix and European processing are likely to keep unit economics under pressure even if platform activity remains robust; therefore, the equity needs demonstrable gross-profit-dollar conversion and EBITDA leverage rather than another volume beat. In a high-long-rate tape, investors will discount the promised operating leverage until it appears in reported margins.

The customer-diversification narrative is directionally constructive but does not eliminate concentration risk: a major customer’s move to multi-processor architecture creates a template for other large accounts to negotiate share and price. The 2028 renewal is not the near-term event risk; the nearer 1-3 month risk is evidence that new issuance diversification migrates into existing-card processing, which would make consensus mid-teens “underlying” growth less relevant. A further take-rate decline of more than 1-2bp without offsetting expense leverage would likely compress the multiple.

The underappreciated upside is that value-added services and program management can convert MQ from a low-margin issuer processor into a higher-switching-cost orchestration layer, particularly for North American clients expanding into Europe. That outcome is a 6-18 month catalyst, not a stablecoin catalyst: crypto/stablecoin flows remain too small to underwrite estimates. The most useful near-term proof points are disclosed incremental margins, value-added-services mix, and any tangible economics from the AXP partnership.

Key Decisions for Investors

• Maintain MQ as a watch-to-buy rather than chase conference commentary; initiate only after the next earnings release confirms flat operating expenses and gross-profit growth translating into at least 300bp of year-over-year EBITDA-margin expansion. Thesis is falsified by another material take-rate decline or a reduction to full-year gross-profit guidance.
• For a 3-6 month relative-value position, consider long MQ / short ADYEN in equal dollar beta-adjusted sizing only if MQ demonstrates margin conversion. MQ has more upside to successful enterprise monetization, while ADYEN faces greater valuation sensitivity if enterprise payments growth decelerates; close if MQ loses a meaningful processing share at a top customer.
• Avoid treating AFRM, SEZL and KLAR strength as a clean read-through to MQ. Their transaction growth supports processing volumes, but issuer-processing contracts pass scale economics back to customers; use BNPL results as a volume signal, while requiring MQ-specific take-rate stability before increasing exposure.
• Set an event alert around AXP partnership disclosures over the next two quarters. A named program with implementation timing and economics would justify revisiting a long; absent that detail, assign no valuation credit to the partnership.
