MercadoLibre Stock Falls 12%: Revenue Soars 45% but Margins Shrink

MercadoLibre stock fell 12% on Thursday, November 5, after the Latin American e-commerce and payments giant reported third-quarter earnings that missed Wall Street's profit expectations — even as revenue jumped 45% to $10.75 billion. The sell-off pushed the shares to their lowest close in more than a year and left the stock down about 42% from its 2025 peak, as investors focused on a shrinking operating margin rather than booming sales.

What happened

MercadoLibre reported its third-quarter 2026 results after the US market closed on Wednesday, November 4. Net revenue and financial income rose 45% year over year to $10.75 billion — 41% on a currency-neutral basis — slightly ahead of the roughly $10.66 billion to $10.69 billion analysts had expected, according to LSEG data reported by Reuters. Gross merchandise volume, the total value of goods sold on its marketplace, climbed 38% to $23 billion, while total payment volume through its Mercado Pago fintech arm surged 53% to $109 billion.

Profit, however, came in light. Earnings were $8.83 per share, below consensus estimates that ranged from about $9.30 to $9.41. Net income was $448 million, up about 6% from a year earlier but below the $476 million analysts expected. Operating income was $676 million, also short of the roughly $731 million forecast.

The key number: a 6.3% operating margin

The figure that drove the sell-off was the operating margin. It fell to 6.3% of revenue, down from 9.8% a year earlier and 6.7% in the second quarter. In plain terms, MercadoLibre is keeping far less profit from each dollar of sales than it did a year ago, even though sales themselves are growing at one of the fastest rates of any large e-commerce company.

Shares fell 12% on Thursday, November 5, closing at $1,530.28 — the stock's lowest close of the past year — during a session in which the broader S&P 500 also fell sharply. The stock slipped a further 1.32% on Friday to close the week at $1,510. Over the past month it is down roughly 18%, a slide that began with a 7.8% drop on October 26 after a surprise Brazilian presidential runoff result hit Brazilian assets broadly.

Why it's blowing up

The story spread quickly because it captures a tension investors are wrestling with across tech: how long to tolerate heavy spending in exchange for growth. MercadoLibre expanded its fulfillment capacity by almost 20% in a single quarter, building warehouses and delivery capacity ahead of the peak holiday shopping season. It also lowered free-shipping thresholds, spent more on marketing in Brazil — sales and marketing costs rose to 11.6% of net revenue from 11.2% the prior quarter — and absorbed higher bad-debt costs from its rapidly growing credit business. Its loan portfolio expanded 62% to $17.9 billion, with loans 15 to 90 days past due at 7%, roughly unchanged and near historical lows, according to management.

Chief Financial Officer Martín de los Santos summed up the timing problem on the earnings call: "The quarter when you are building capacity, you don't have the revenues yet, so you have the cost." He said he expects margins to recover in the following quarter as the new capacity fills with holiday orders.

What's next

MercadoLibre does not issue numerical financial guidance, so there is no company forecast for investors to lean on — the margin recovery management described rests on execution in the holiday quarter. That makes the fourth-quarter report, expected in February 2027, the next real test: if the new fulfillment capacity delivers peak-season volume and the operating margin rebounds as promised, the spending will look deliberate; if margins stay near 6%, the debate over the company's investment cycle will only get louder. For now, the market's verdict is clear — growth alone was not enough this quarter.
