Shares of MercadoLibre (NASDAQ:MELI) declined more than 5% in premarket trading on Thursday, as investors weighed the company's record second-quarter revenue against a concerning squeeze on profitability. The stock fell 5.2% to $1,822.98 ahead of the market open, reflecting a cautious stance from the investment community.
The Latin American e-commerce and fintech giant reported revenue of $10.2 billion for the quarter, a 50% increase year-over-year and roughly 5% above the $9.7 billion consensus estimate compiled by LSEG. However, operating income came in at $683 million, down 17% from the year-ago period, while net income slipped to $466 million, an 11% decline. Both figures beat analyst expectations, but the margin contraction drew the most attention.
The company's incremental operating margin—defined as the change in operating income divided by the change in revenue—was negative 4.2%. In other words, for every additional dollar of revenue generated, operating profit declined by about four cents. This metric underscores the rising costs associated with MercadoLibre's aggressive expansion, particularly in free shipping promotions in Brazil and higher provisions for its growing credit card portfolio.
This marks the third consecutive quarter of declining net income, even as revenue growth accelerates. Operating margins have narrowed from 10.1% in Q4 2025 to 6.9% in Q1 2026 and further to 6.7% in the latest quarter. The credit portfolio has expanded by over $3.5 billion during this period, reaching more than $16 billion, a 75% increase year-over-year.
Michael Miller, an analyst at Morningstar, echoed market concerns: "Similar to last quarter, the market is focusing on the year-over-year decrease in net income." The market's reaction suggests that while top-line growth remains robust, investors are increasingly questioning the sustainability of the company's investment-heavy strategy.
MercadoLibre management, however, argues that these investments are cultivating a higher-value customer base. The number of users active on both the marketplace and payments platform rose 37% year-over-year. These dual-platform users generate 70% more merchandise volume than marketplace-only users and nearly 90% greater payment volume compared to fintech-only users. Chief Financial Officer Martín de los Santos stated, "We will continue investing with discipline."
Credit quality metrics remain a watch item. Total delinquency in the 15-to-90-day range stood at 7.0%, up 0.3 percentage points from a year earlier but down one point sequentially. The larger credit book heightens exposure to consumer stress, though management points to improving sequential trends.
Wall Street sentiment is predominantly bullish, with nine buy ratings, four holds, and no sells among 13 analysts tracked. The average 12-month price target of $2,152.50 implies an 18.1% upside from the premarket level. Targets range from $1,750 (UBS) to $2,600 (Jefferies), reflecting a wide divergence in views on the company's growth trajectory versus margin pressures.
MercadoLibre has scheduled its next investor event for September 8. In the near term, analyst updates and trading momentum following the earnings release are expected to drive market activity. The core question for investors remains whether the company can translate its ecosystem expansion into positive incremental margins, a key test for the stock's premium valuation of 50.8 times trailing earnings.
