MercadoLibre Inc. reported mixed second-quarter results, sending the Latin American e-commerce and fintech company’s shares down roughly 3% in after-hours trading. Revenue handily exceeded Wall Street expectations, yet earnings fell short as higher costs trimmed profitability. Net revenue rose 34% year on year to $6.79 billion, beating analyst forecasts of about $6.6 billion. Operating income reached $825 million, giving a 12.2% margin, while net income came in at $523 million, missing the consensus estimate of roughly $615 million. Earnings per share were about $10.3, compared with analysts’ $11.9 projection. MercadoPago, the company’s fintech arm, processed $64.6 billion in total payment volume, a 39% annual increase on a currency-neutral basis. Gross merchandise volume on the marketplace climbed to $15.26 billion, also ahead of expectations. MercadoLibre, which operates in 18 countries, will discuss the results on a conference call later on Monday.
