MercadoLibre Stock Plunges on Profit Miss: Time to Buy?

MercadoLibre reported second-quarter results that showed impressive revenue growth but continued pressure on profitability. Revenue jumped 45% to $10.75 billion, beating analyst estimates of $10.71 billion. Both core businesses performed well: gross merchandise volume rose 38% to $23 billion, and total payment volume surged 53% to $109 billion.

However, operating income fell to $601 million from $636 million a year earlier, and the net income margin was just 4.2%. Earnings per share came in at $8.83, up from $8.32 but below the $9.27 analysts expected. The company has been investing heavily in lower free shipping thresholds, expanded logistics, and its credit business, which has weighed on margins.

Investors reacted negatively, sending the stock down 12% on Thursday. The sell-off reflects growing impatience with the company's investment cycle, especially since MercadoLibre doesn't provide guidance, leaving analysts and investors to guess when margin expansion will return.

Despite the profit decline, the company gained market share in its three largest markets—Brazil, Mexico, and Argentina—which should ease concerns about competition from Amazon and Sea Limited's Shopee. Management also highlighted that e-commerce penetration in Latin America is increasing at its fastest pace since the pandemic, providing a tailwind for its investments.

The credit portfolio grew 62% to $18 billion, with stable default and interest metrics. While new credit card issuances require provisions for expected losses upfront, management believes this business will contribute to profit growth over time.

The profit decline matters because it raises questions about when MercadoLibre's investments will pay off. The company is spending heavily to build a moat around its e-commerce and fintech businesses, similar to Amazon's strategy in the U.S. This includes faster shipping, lower free shipping thresholds, and expanding its credit offerings. While these investments are driving strong top-line growth and customer engagement, they are compressing margins in the near term.

Investors are concerned because there is no clear timeline for margin recovery. Without guidance, it's difficult to model future profitability, which increases uncertainty and puts pressure on the stock. The 12% drop on Thursday reflects this frustration, and the stock is now down 42% from its 2025 peak, hitting its lowest point in over two years.

However, the investments appear to be working. Cost per shipment in Brazil has fallen 5% year-over-year and 14% since the first quarter of 2025, indicating improved logistics efficiency. Customer engagement is strengthening, with buyers making an average of 12 purchases per year compared to over 50 in developed countries, suggesting significant room for growth. As purchase frequency increases and more customers adopt multiple products, revenue and margins should improve over the long run.

The competitive landscape also matters. MercadoLibre is holding its own against Amazon and Shopee, and the rapid e-commerce penetration in Latin America provides a growing pie for all players. If MercadoLibre can continue to gain share while investing in its ecosystem, it could emerge stronger once the investment cycle matures.

For investors, the key question is whether the current sell-off is overdone. The stock looks oversold, and the long-term growth potential across e-commerce and fintech remains substantial. However, a recovery could take several quarters, and there is risk that margins remain under pressure longer than expected.
