MercadoLibre heads into its third-quarter report with a familiar split personality. Demand across its marketplace, credit and advertising businesses is accelerating, yet profit growth keeps lagging far behind. When the company reports after the close on November 4, the real question is not whether sales will grow quickly. It is whether the margin erosion that has defined the past year is finally leveling off, or whether new cost pressures flagged last quarter are pushing it deeper.
The consensus numbers capture that tension. Analysts expect revenue of about $10.66 billion, up roughly 44% from $7.41 billion a year ago and a solid step up from last quarter's $10.17 billion. Earnings, however, are forecast at $9.41 per share, only about 13% above the year-ago $8.32 and barely ahead of the prior quarter's $9.19. Revenue growing more than three times faster than earnings tells you the Street already assumes another quarter of heavy reinvestment. MercadoLibre does not issue formal guidance, so the market is leaning entirely on how management framed its priorities last time. That framing was consistent: growth first, with profitability expected to follow from scale.
Last quarter offered plenty of support for the growth half of that story. Items sold in Brazil rose 56%, an acceleration from the low-to-mid 40s in the prior two periods, and conversion gains were described as a durable improvement one year after the free-shipping threshold was lowered. The credit book swelled to $16.4 billion, up 75%, while risk-adjusted interest margins recovered to 21% from 18% as Brazilian consumer provisions normalized. Advertising grew about 73%, and cross-border volume from China surged. Validation this quarter would look like Brazil volumes holding near that pace, advertising staying in the high double digits and credit margins holding around the 21% level even as the portfolio expands.
The cost side is where the narrative could crack. The operating margin was 6.7% in the second quarter, down 550 basis points from a year earlier and essentially flat sequentially. Management pointed to deliberate take-rate cuts and PIX discounts in Brazil, a one-off device restock in Mexican acquiring, and higher chip and memory costs it described as structural. Logistics and energy costs were also not fully passed through to users. Meanwhile, credit card margins sat in negative territory as Brazilian issuance accelerated sharply, and 90-day delinquencies rose, which management attributed to a shift toward shorter-duration loans. A stable or modestly improving margin would suggest the worst is behind the company. Another leg down, particularly paired with rising late-stage delinquencies, would revive concerns about the Brazilian credit cycle heading into 2027.
Mexico is the other swing factor. Gross merchandise volume there decelerated on tax reform, softer macro conditions and a World Cup drag that management said deepened in June and July. Evidence of stabilization would ease worries that the company's second-largest market is losing momentum just as cost pressures there intensify.
The market has not been generous in the meantime. Shares have fallen 8.6% since the last report, trailing the S&P 500 by eight points, and at about $1,669 the stock sits below its 200-day moving average of roughly $1,827 and much closer to the bottom of its post-earnings range than the $2,066 top. Sentiment has nonetheless warmed considerably, with the bearish reading shrinking from nearly 23% last quarter to under 3% now. That combination suggests a market that has priced in some margin pain but is less fearful than before. Ultimately, this report hinges on one thing: whether accelerating engagement and the new ecosystem economics management highlighted can start translating into a steadier operating margin. Without that, even another quarter of spectacular growth may not be enough to change the stock's direction.
