Sezzle (SEZL) has jumped onto investor watchlists after its first quarter 2026 report, which combined higher sales and net income, a lift to full year guidance, and a larger, lower cost credit facility.

Those strong first quarter numbers, the raised 2026 guidance, the new US$300 million credit facility, and a completed share repurchase appear to be feeding into strong momentum. Sezzle’s 30 day share price return of 52.12% and year to date share price return of 58.77% far outpace its 14.81% total shareholder return over the past year.

With Sezzle now trading around US$103.44 and sitting close to analyst targets, the key question is whether the recent surge and raised 2026 guidance still leave room for upside or if the stock already reflects future growth.

Most Popular Narrative: 18.7% Overvalued

According to the most followed narrative on Sezzle, the current share price of $103.44 sits well above an estimated fair value of $87.18, which frames the recent rally as rich against long term assumptions.

Sezzle Inc. (SEZL), a buy-now-pay-later (BNPL) fintech provider, has experienced volatile growth since its public debut, but structural headwinds in the BNPL sector, intensifying competition, escalating credit risks, regulatory pressures, and potential dilution, cast doubt on its long-term viability as a high-growth story. This thesis argues that SEZL’s path to mid-cap status (market cap exceeding $2 billion) is speculative at best, with slowing revenue growth, persistent bad debt provisions, and international expansion risks likely to compress multiples and erode shareholder value.

Curious why this narrative still sees room between price and fair value? The core hinges on how fast revenue can compound and how long margins can hold up. The real tension sits in what happens to credit costs if expansion continues at the current pace.

Result: Fair Value of $87.18 (OVERVALUED)

However, this bearish view could be challenged if credit losses stay contained and regulators take a lighter touch on BNPL practices than initially feared.

Another View: Multiples Point To A Tighter Valuation

While the most popular narrative sees Sezzle as 18.7% overvalued against a fair value of $87.18, its current P/E of 23.5x sits only slightly below a fair ratio of 24.3x and below peer averages of 27x, yet above the wider US diversified financial industry at 18x. This raises the question of whether the real risk is that expectations are already tightly priced in.
