Mercado Libre accelerated revenue growth but results were weighed down by higher costs in Q4. Fourth-quarter revenue climbed 45% year‑over‑year to $8.8 billion, beating expectations, yet the company reported weaker profits as operating margin contracted by 340 basis points to 10.1%. The report highlights a contrast between robust top‑line momentum and continued margin pressure, with higher expenses cited as the main drag on earnings. Management flagged that costs remained elevated into the quarter, limiting improvements in profitability despite strong sales expansion. Investors will likely focus on whether cost control and margin recovery can keep pace with the company’s rapid revenue growth in the coming quarters. #MercadoLibre #MELI #FiatNews
