MercadoLibre (MELI) shares gained 1.80% to $1,922.57 during regular trading before falling 4.65% in after-hours activity to $1,833.13. The after-hours decline came despite strong second-quarter performance spanning commerce, payments, advertising, and technology operations. Lower operating margins and continued spending on expansion initiatives offset the record revenue figures. As Latin America's largest e-commerce and fintech platform, operating across 18 countries, MercadoLibre's results underscore the accelerating pace of digital commerce adoption in a region where online retail penetration still trails more developed markets.

Net revenue and financial income reached $10.2 billion, a 50% increase year over year. The result marked the company's 30th consecutive quarter with growth above 30% and the fastest growth rate in four years. The Latin American commerce and fintech operator also surpassed $10 billion in quarterly revenue for the first time.

Operating income reached $683 million, producing an operating margin of 6.7% for the quarter. Net income totaled $466 million, representing a 4.6% margin despite the substantial top-line growth. Expenditures related to shipping, credit cards, product selection, cross-border trade, and membership programs constrained near-term profitability. The margin profile reflects a reinvestment strategy common among large-scale marketplace operators prioritizing ecosystem depth over near-term profitability.

Commerce Growth Accelerates Across Major Markets

Commerce revenue increased 50% to $5.8 billion as demand strengthened across major Latin American markets. Gross merchandise volume reached $22 billion, rising 36% on a currency-neutral basis and 44% in dollar terms. Total items sold climbed 45% to 795 million, supported by broader product selection and faster delivery.

Brazil led regional growth with currency-neutral merchandise volume up 39% and sold items increasing 56%. Mexico recorded 26% merchandise volume growth, while item sales advanced 34% despite pressures from tax reform. Argentina posted 38% merchandise volume growth and 22% higher item sales amid weak consumer demand.

Unique active commerce buyers grew 26% to 89 million, and purchases per buyer increased 14%. Brazil's reduced free-shipping threshold continued to drive higher purchase frequency, broader category adoption, improved retention, and higher conversion rates. Cross-border merchandise volume rose 60%, while China fulfillment activity expanded 170% from the previous quarter, connecting Latin American consumers directly with international suppliers and deepening the platform's product selection.

Mercado Pago and Advertising Drive Ecosystem Expansion

Mercado Pago revenue rose 49% to $4.4 billion as payment activity expanded throughout the region. Total payment volume exceeded $100 billion for the first time, reaching $101 billion after 56% growth. Monthly active fintech users increased 30% to 88 million, with Brazil and Mexico leading the gains.

Assets under management climbed 68% to $23 billion, while average assets per user increased 29%. The credit portfolio expanded 75% to over $16 billion, including a $7.7 billion credit card portfolio. MercadoLibre issued 2.6 million cards, and portfolio delinquency remained near historical lows at 7.0%. The fintech expansion serves a region where traditional banking and credit access have historically lagged developed markets, positioning Mercado Pago as both a growth driver and a credit-risk metric to monitor as the portfolio scales.

Advertising revenue increased 73% in dollar terms as more sellers adopted automated campaign and budget tools. Ecosystem users grew 37%, reinforcing engagement across both the MercadoLibre marketplace and Mercado Pago services. The company also completed its upgraded search rollout across five markets, yielding improvements in conversion and click-through rates.
