Sezzle Inc reported strong financial results for the first quarter of 2025, significantly surpassing market expectations. The company raised its guidance following robust demand growth. Total revenue increased by 123.3% year-over-year, while gross merchandise volume (GMV) reached $808.7 million, marking a 64.1% increase compared to the same period last year. Operating income surged by 260.6% year-over-year. These results contributed to a sharp rise in Sezzle's stock price, which climbed over 32% in pre-market trading and reached new all-time highs, trading above $83 per share in May 2025, up from just $1 in December 2023. The strong performance has also negatively impacted short sellers, as indicated by a decline in short interest.
