MercadoLibre Grew Revenue 49% and Got Punished for It

Hedge fund WCM sold approximately $940 million worth of MercadoLibre stock, according to regulatory filings. That's not a trim — that's a liquidation. The exact timing and filing type (13F or Form 4) should be confirmed when the next quarterly disclosure is published, but the scale of the exit is not in dispute.

The mechanics matter less than the signal. WCM's reversal shows that smart money is rethinking whether Mercado Pago's lending business will actually pay off. WCM was a long-term conviction holder — the kind of fund that builds a position over years because it believes in the fintech flywheel. When that type of investor exits entirely, it suggests the thesis itself has changed, not just the quarter's numbers.

The volume tells the story. MELI traded at nearly five times its 20-day average volume on the sell-off day. With a beta (how much the stock moves when the broader market moves 1%) of 1.41 — meaning MELI typically swings about 40% more than the broader market — this kind of institutional exit creates outsized price damage. Amazon and Sea Limited (Shopee) are both spending big now to profit later in Latin America. But neither stock saw a similar single-fund sell-off. That tells us the WCM exit was about MELI specifically — not a broad shift away from the sector.

Before the May 7 earnings report, MELI had been trading at a trailing P/E (how many years of past earnings the stock costs) of about 41x. That's an expensive ticket. Investors were paying that price because they believed MELI could grow revenue fast AND keep profits rising.

Q1 broke that assumption. Revenue grew 49%, but net income shrank 16%. Management made a clear choice: grab market share and build the ecosystem now, even if it means lower profits in the short term. They poured money into free shipping, credit expansion, and logistics.

What makes MELI's repricing particularly violent is its shareholder composition. MELI is not included in most major emerging-market indexes, which means passive EM funds don't provide a natural floor of buying support. The shareholder base skews toward active growth funds with strict drawdown (the peak-to-trough decline in the stock's price) limits. When the first big holder exits, there's no index-tracking bid to absorb the supply. The stock was sitting near its 52-week low of $1,593.21 as of early May 2026, with very little cushion before entering truly uncharted territory.

MELI didn't just increase shipping subsidies. It ramped up credit expansion through Mercado Pago, its fintech arm. Revenue from financial services helped push total revenue to $8.85 billion, but margins compressed in the process.

The company's operating margin (profit from operations as a percentage of revenue) dropped to roughly 7% — $611 million on $8.85 billion in revenue. For context, gross profit was $3.86 billion, meaning the company is spending enormous sums between the gross profit line and the operating income line.

Rapid credit expansion in emerging markets during a period of declining profits is a combination that makes risk managers nervous. If loan losses spike in Brazil, Mexico, or Argentina, the profit picture gets worse before it gets better. According to MercadoLibre's Q1 2026 earnings release, Brazil alone generated $4.77 billion in revenue, making it the single biggest concentration risk.

Between approximately 2022 and early 2026, MELI grew from about 30,000 employees to nearly 124,000 — but 95% of those employees adopted generative AI tools in their daily work. According to MercadoLibre's Q1 2026 earnings presentation, about 30% of code reaching production was written with AI assistance as of Q1 2026.

The company also reported a 40% increase in merged code contributions, while IT staff grew only 11% year-over-year. In other words, each engineer is producing significantly more output.

This matters because the central bear case is that MELI is spending too much. If AI tools let the company scale output without proportional headcount growth, the investment cycle could be shorter than skeptics expect. Engineers are already getting more done with less. The question is whether those gains hit the income statement fast enough to keep Wall Street happy.

CEO Ariel Szarfsztejn took over on January 1, 2026, when founder Marcos Galperin moved to Executive Chairman. His target long-term incentive award for 2026 is $14 million. The CFO's is $4 million, and Executive Chairman Galperin's is $3.5 million. The payout was calculated using the stock price divided by the average closing price during the final 60 trading days of 2025 — a comparison window that has already closed.

With MELI now trading well below those late-2025 levels, the C-suite's compensation is taking a direct hit. Management has a very personal financial incentive to get the stock moving in the right direction.

That doesn't guarantee a shift toward profitability. But it does mean management will feel real pain if the investment-heavy strategy doesn't start producing results. When executives have skin in the game at this scale, they tend to be more responsive to shareholder concerns about margins.
