MercadoLibre's 50% Revenue Surge Masks a Profit Squeeze That Has Investors Wary

MercadoLibre hits $10.2B quarterly revenue, up 50% YoY, but net profit falls and operating margin drops to 6.7%, sparking investor concerns over heavy spending.

Latin America's e-commerce and fintech powerhouse just posted a blockbuster quarter — yet the market's reaction was anything but celebratory. MercadoLibre crossed the $10 billion quarterly revenue threshold for the first time, but the milestone came wrapped in a troubling package: shrinking margins and a net profit decline that sent shares lower in after-hours trading.

The Buenos Aires-based company reported second-quarter 2026 net revenue and financial income of $10.2 billion, up roughly 50% year over year — the fastest growth clip in four years. Gross merchandise volume jumped 44%, while payment volume surged 56%. Earnings per share landed at $9.19, beating expectations. But net income fell to $466 million from $523 million in the prior-year period, and the operating margin compressed to 6.7% from 12.2%.

The Margin Conundrum

That margin erosion is the crux of the debate now swirling around the stock. Operating income dropped to $683 million from $825 million a year earlier, and for the first half of 2026, net profit declined 13% to $883 million even as revenue expanded by half. Management attributes the squeeze to heavier spending on free shipping and the aggressive rollout of its credit card business — costs it's willing to absorb in pursuit of market share across the region.

The company's message is unambiguous: dominance in Latin America's commerce and fintech landscape matters more than near-term profitability. Executives confirmed on the earnings call that investment in trade, fintech, logistics, and artificial intelligence will continue, even at the expense of short-term margins. Capital expenditures reached $441 million in the quarter.

Investors are left to weigh whether this is a temporary price for growth that will pay off handsomely, or a structural problem that could become entrenched.

Credit: The Engine and the Expense

The lending operation sits at the heart of both the growth story and the cost pressure. MercadoLibre's credit portfolio expanded 75% to $16.4 billion, and the net interest margin after losses improved sequentially from 18% to 21%. That improvement suggests credit quality isn't the issue — rather, the sheer speed of scaling is what's generating costs.

For bulls, the ecosystem dynamics are compelling. Users who engage with multiple MercadoLibre services generate 70% more gross merchandise volume and purchase 55% more items than those using a single service. In Brazil, items per buyer rose 19% and conversion rates improved by 1.1 percentage points. If the net interest margin continues to strengthen while the credit book grows, operating margins could recover in coming quarters without sacrificing revenue growth.

Wall Street's Split Personality

Analyst reaction to the results has been largely constructive, though far from unanimous. Cantor Fitzgerald raised its price target on August 6 from $2,150 to $2,300, maintaining an Overweight rating — a signal that it values the core growth momentum over the temporary margin weakness. Morgan Stanley sees the stock at $2,450, and Scotiabank is even more bullish at $2,800. The consensus target sits near $2,272, well above current levels.

But Citigroup and UBS remain on the sidelines with Neutral ratings and price targets of $2,000 and $1,750 respectively — noticeably closer to where the stock trades now. That divergence underscores the uncertainty surrounding the margin trajectory.

Institutional investors appear to lean optimistic. Several funds, including Handelsbanken Fonder and Oppenheimer Asset Management, added to their positions in August, with multiple funds increasing holdings by 2% to 3%.

A Stock Searching for Direction

The market's ambivalence is visible in the price action. Shares trade around €1,588.20, just above the 50-day moving average and roughly 1.2% below the 200-day average. The stock is down 7.4% year to date and 20% over the past twelve months. From the 52-week high of €2,164.50 set in late September, the shares remain 27% off the peak.

The technical picture offers little clarity: the relative strength index sits at 49.3, indicating the stock is neither overbought nor oversold. With annualized volatility at 34%, the shares are clearly in a consolidation phase, waiting for a catalyst.

A discounted cash flow analysis suggests the stock is significantly undervalued, according to analysts, though the price-to-earnings ratio of roughly 50 remains steep against a sector average of about 20. That valuation premium leaves little room for error — if margins keep sliding, the multiple becomes harder to justify.

What to Watch

The next real test comes with the third-quarter report, when investors will learn whether the Q2 margin compression was a one-off episode or the beginning of a trend. If the net interest margin in the credit business keeps improving and ecosystem growth continues to lift conversion rates, the bull case remains intact and the more optimistic price targets stay in play.

But if operating margins deteriorate further without compensating improvements in credit quality, the skeptics' view could gain traction. For now, MercadoLibre is a company growing at a remarkable pace — and paying a visible price for it. Whether that price is an investment or an expense is the question the market hasn't yet answered.
