MELI: Credit Growth Strengthens Ecosystem but Margin and Credit Risk Remain Key Concerns

What happened

MercadoLibre's Q2 2026 results show its credit portfolio surging 75% year-over-year to $16.4 billion, driven by aggressive card issuance and deeper engagement with Mercado Pago. This expansion strengthens the company's fintech ecosystem by increasing cross-sell opportunities and transaction volumes, but it also raises credit risk: allowance for doubtful accounts rose to $4.379 billion and past-due loans to $4.638 billion. While top-line growth remains exceptional (43% GMV growth and 53% TPV growth), operating margin compressed to 6.8% in the first half of 2026 from 12.5% a year earlier, primarily due to higher shipping costs and credit provisions. The market must now weigh the strategic upside of fintech scale against the deterioration in earnings quality and the potential for prolonged margin pressure. With the stock trading at around $1,830 and no margin of safety, the DeepValue master report rates MELI a WAIT, emphasizing that the next two quarterly filings will determine whether the current investment cycle is paying off.

Implication

The credit portfolio's jump to $16.4 billion is a significant milestone for the fintech ecosystem, but it also intensifies the focus on underwriting quality as provisions and past-due loans have risen sharply. If the next two quarterly filings fail to show operating margin recovering above 8% and allowance growth decelerating relative to loan growth, the stock's downside risk increases given its rich valuation (49.8x trailing earnings) and elevated net debt ($7.7 billion). Conversely, if management can demonstrate that logistics costs are stabilizing and credit losses are contained, the bull case for fintech cross-sell lifting monetization becomes more credible, potentially supporting a move toward $2,100. In the interim, investors should monitor the direct contribution margin (15.9% in Q1 2026) and the ratio of allowance to gross loans as key early indicators of whether the reinvestment cycle is working. A more attractive entry point would be around $1,650, where the risk/reward becomes more favorable if the fundamental outlook remains intact.

Thesis delta

The new credit growth data reinforces the fintech ecosystem's strategic strength, confirming that Mercado Pago engagement is deepening. However, it does not alter the core concern that the company's aggressive loan expansion is outpacing its reserve build, adding downside risk to earnings quality. The WAIT rating remains appropriate until the next two filings show either margin recovery above 8% or deceleration in reserve growth, which would signal that the investment cycle is nearing payback.
