MercadoLibre: 3 Key Takeaways for Long-Term Investors

On its third-quarter 2026 earnings call, held on Nov. 4, 2026, MercadoLibre (NASDAQ:MELI) announced an FX-neutral revenue increase of 41% year over year alongside $676 million in operating income. Management sacrificed 40 basis points of operating margin to fund logistics capacity and affiliate marketing. Long-term investors need to know if these upfront spending choices build lasting competitive advantages. Three key takeaways from management explain how these capital choices position the business.

1. Logistics Expansion Sacrifices Short-Term Margin for Scale

MercadoLibre expanded its fulfillment footprint by nearly 20% in the third quarter ahead of the peak shopping season, incurring upfront costs before shipping volume arrived. Despite these short-term shipping headwinds, shipping cost per unit in Brazil dropped 5% year over year on an FX-neutral basis.

We added almost 20% to our fulfillment square meters quarter-on-quarter ahead of peak. That cost lands before the volume does, a pattern we have seen many times since we started operating fulfillment almost 10 years ago.
-- Martin de los Santos, Chief Financial Officer

2. Affiliate Marketing Investments Drive Social Commerce Acceleration

Management allocated extra capital to its social media creator network in Brazil, pushing sales and marketing expenses up 40 basis points sequentially to 11.6% of net revenue. The regional affiliate network surpassed 12 million members, expanding product discovery beyond traditional search channels.

Orders through the channel grew 240% year-on-year. Consumers increasingly discover and buy products through creators and social media.
-- Martin de los Santos, Chief Financial Officer

3. E-Commerce Customer Data Protects Credit Portfolio Performance

MercadoLibre expanded its credit portfolio 62% year over year while maintaining non-performing loans, or NPLs, aged 15 to 90 days at 7%. First-party shopping data from the marketplace allows the company to evaluate buyer risk before issuing credit lines.

And coming back to Brazil, I would say that an important advantage is that the marketplace gives us information before we lend. And we see how users buy, how they pay, how they use installments.
-- Osvaldo Gimenez, President of Fintech

Looking Ahead

Executive focus remains centered on artificial intelligence integration and proprietary ecosystem features. Internal development efforts prioritize in-house software capabilities over external platform integrations to safeguard customer relationships.

Our priority is still to build the best agentic experience inside MercadoLibre, taking advantage of the 27 years of first-party data that we have, our unique combination of selection, pricing, logistics, financing, loyalty and so on.
-- Ariel Szarfsztejn, Chief Executive Officer

Scale advantages across shipping and payments reinforce the company's competitive moat against regional rivals. Continued capital deployment into fulfillment efficiency and financial services underpins management's multiyear expansion strategy.

MercadoLibre is extending its leadership as the go-to destination for shopping in Latin America. Mercado Pago is getting closer to its objective of becoming the regional largest digital financial services provider in the region...
