Pricesmart (PSMT) shares plunged 7.15% in after-hours trading on Wednesday following the release of its fiscal first-quarter earnings report that missed analysts' expectations on profitability despite reporting higher revenue.

The membership-based warehouse club operator recorded a net income of $37.4 million, or $1.21 per diluted share, for the quarter ended November 30, 2024. While this represented a 7.8% increase in revenue to $1.26 billion from $1.17 billion a year earlier, it fell short of the consensus estimate of $1.31 per share from analysts polled by FactSet.

The earnings miss appeared to be driven by rising costs that outpaced the company's revenue growth. Operating expenses climbed 8.2% year-over-year to $1.2 billion, with warehouse club and other operations expenses increasing 7.1% and general and administrative expenses up 20.1%. This resulted in operating income remaining essentially flat at $58.3 million compared to $58.2 million in the prior-year period.
