Sezzle Q1 2026: Growth Deceleration Confirms DeepValue's Cautious Stance

What happened

Sezzle reported Q1 2026 revenue of $135.5 million (+29.2% YoY) and GMV of $1.1 billion (+37.3% YoY), both beating raised guidance but marking a sharp deceleration from the 60%+ growth rates of 2025. Adjusted EBITDA margin surged to 52.5%, driven by ongoing fee income and operating leverage, yet the company's own FY2026 guidance of 30-35% revenue growth signals a structural slowdown. The DeepValue master report had flagged the risk of growth normalization and the fragility of high margins built on consumer fees and loose underwriting. While the adjusted net income guidance was raised to $180 million, the implied growth trajectory is well below the hyper-growth narrative that supported the stock's elevated multiple. The combination of decelerating top-line growth, continued reliance on fee income, and a $100 million buyback program leaves little room for error in a regulatory and credit environment that remains uncertain.

Implication

Sezzle’s strong Q1 margins mask a fundamental shift to slower growth. The FY2026 guidance confirms the DeepValue report’s base case of moderating expansion, making the current ~27x P/E unsustainable. With credit costs and regulatory risks still present, investors should trim positions or wait for a deeper pullback to the $60 attractive entry zone identified in the report. The bull case of sustained 60% growth is off the table, and the bear case of sub-30% growth and margin pressure becomes more probable.

Thesis delta

The investment thesis shifts from 'high-growth compounder' to 'moderate-growth margin story'. The key now is whether Sezzle can maintain its elevated margins (52%+ EBITDA) as growth slows—or if fee dependence and credit deterioration compress margins toward the mid-20s. The DeepValue report's base case ($80) looks achievable, but the bull case ($110) is much less likely, while the bear case ($55) remains a risk if credit or regulatory headwinds materialize.
