To our Shareholders Q3’24 Results We are pleased to report another quarter of growth in Q3'24. Momentum is strong across the business, with solid growth in unique buyers, Fintech monthly active users (MAU), GMV, the credit portfolio and acquiring TPV in all major geographies. We believe we are making excellent progress on our long-term strategic goals of increasing the penetration of online commerce in Latin America, becoming the principal financial services provider to users of Mercado Pago and scaling our acquiring business. Our competitive position is strengthening as retention improves across our businesses. This gives us great confidence as we invest to fully capitalize on the many growth opportunities that are ahead of us, knowing that our ecosystem is uniquely placed to capture those opportunities. Net revenues & financial income of $5.3 billion, up 35% YoY and 103% FX-neutral Income from operations of $557 million, with a 10.5% margin Net income of $397 million, with a 7.5% margin $50.7 billion Total Payment Volume, up 34% YoY and 73% FX-neutral $12.9 billion Gross Merchandise Volume, up 14% YoY and 71% FX-neutral ͏MONTEVIDEO, Uruguay; November 6th, 2024 -- MercadoLibre, Inc. (Nasdaq: MELI) (http://www.mercadolibre.com), Latin America’s leading e-commerce and fintech company, today reported financial results for the quarter ended September 30, 2024. Commerce We are excited about the prospect of driving offline retail online in Latin America, where ecommerce penetration lags the USA by almost a decade. We see a huge runway for growth. We executed well on this opportunity in Q3'24, with very strong FX-neutral GMV growth of 34% YoY in Brazil and 27% YoY in Mexico. In Argentina, items sold grew by an impressive 16% YoY as consumption trends continued to improve. Market share grew in all major geographies. Unique buyers across the region reached almost 61mn, rising 21% YoY. This is the second quarter in succession that unique buyer growth has accelerated to a new post-pandemic high. This performance reinforces our conviction in the investments we are making to capture the long-term, structural growth opportunities ahead of us. Offline to online is a secular trend, but it doesn't happen in a vacuum; it is fueled by innovation and investment to constantly improve the online buying experience. Initiatives in Q3'24 included the launch of installation appointments for autoparts, bulk purchase discounts in apparel, virtual try-on for makeup and dynamic pricing tools for sellers. Despite being the leading ecommerce platform with 25 years of history in the region, we still see plenty of scope to expand our user base given the population of more than 650mn in Latin America. In Q3’24 we split our loyalty scheme, MELI+, into two tiers called “MELI+ Essencial” and “MELI+ Total”. "Meli+ Essencial", at just below $2 per month, provides users with a unique package of ecosystemic benefits including a lower threshold for free shipping, extra installments on purchases in Mercado Libre and cashback on purchases on and off Mercado Libre. The “MELI+ Total”, at roughly $5 per month, includes all these ecosystemic benefits plus access to content from Disney+ and Deezer, and discounts on other streaming services. With these changes, we are extending the reach of our loyalty scheme providing more value to users. 1 MercadoLibre, Inc. Letter to Shareholders

Fintech Services We have great momentum in Fintech Services as more users choose Mercado Pago as their financial services partner. MAU rose 35% YoY to 56mn in Q3'24. Engagement is rising, with "power users" (those transacting in nine out of the last twelve weeks) growing at a much faster rate, and transactions and products per MAU also rising. The expansion of our credit offer, particularly the Mercado Pago credit card, and rising awareness of our remunerated account are driving this performance, as well as NPS gains. The credit card had another good quarter in Q3'24, with the portfolio of $2.3bn growing strongly by 172% YoY and 28% QoQ. We are scaling the credit card at pace because our scoring models are increasingly accurate and our older cohorts are showing a good path towards profitability (with solid NIMAL spreads), with some of them already being profitable. In Q3’24 we invested $76mn in scaling our credit card portfolio. Despite short- term margin pressure, these investments are strategically important because the credit card drives the adoption of Mercado Pago as a principal account and brings positive ecosystemic behavior. The total credit portfolio grew at its fastest pace since Q1'22, rising 77% YoY to $6.0bn. Growth was strong across products and geographies. The consumer book grew 37% YoY, helped by successfully extending larger, longer duration loans to lower risk users in Brazil, Mexico and Argentina. The portfolio in Argentina reached record levels and delivered solid profitability. We also surpassed the milestone of $1bn in merchant loans across the region for the first time. Our consumer and merchant loans are a solid source of profitability that more than offset the investments in our credit card. The NIMAL spread of 24% fell 13ppts YoY, despite solid asset quality indicators with broadly stable roll rates and the 15-90 day NPL of 7.8%. There were three reasons behind the reduction in NIMAL: the ramp up of the credit card, the move upmarket in consumer and merchant credit, and the overall acceleration of our credit originations in the quarter. As we scale the credit card, its share in the total portfolio rose from 25% in Q3'23 to 39% in Q3'24. This created a negative mix effect on NIMAL, because the credit card is a structurally lower spread product. The second reason for the NIMAL decline was our strategic decision to continue moving upmarket with our credit offering to lower risk users with lower spreads. This is incremental to portfolio dollars and has a positive impact on NPS. Finally, we accelerated our origination across products in this quarter and, given that we provision our expected losses up front, this resulted in higher bad debt in this quarter. Our logistics network is a powerful tool to drive offline retail online by providing a better user experience for both buyers and sellers. Fulfillment leads to higher GMV growth because of faster delivery promises, higher conversion and stronger buyer and seller NPS. This is a self-reinforcing process that repeats as we increase fulfillment. This is the reason why we continue investing in expanding our logistics infrastructure to increase the penetration of fulfillment in Brazil and to keep up with the strong pace of growth in our Commerce operation in Mexico. As such, we opened five fulfillment centers in Brazil in Q3'24, plus one in Mexico. Although new facilities can create short-term margin pressure, they are critical to our long-term growth, scale and cost dilution. 1P GMV surpassed last year's peak quarter (Q4'23) due to growth of 62% YoY in Q3'24. Our strategy of expanding our product assortment at competitive prices where there are gaps in our 3P selection is succeeding. We introduced presale functionality for the iPhone 16 launch, for which we had a full assortment and competitive prices. We also had exclusivity for the launch of the Motorola G85, an accessible smartphone with a premium design. These examples show how 1P is turning MELI into a destination for categories in which we have historically had less presence in. As we scale 1P, we continue to see improvements in its profitability. As such, 1P did not act as a drag on the YoY evolution of our income from operations margin Q3'24. Advertising is a strong profit driver for Mercado Libre, with significant potential for growth as the digital Retail Media trend gathers steam and first-party data becomes increasingly important. We also see growth opportunities as we build our presence in advertising formats beyond Product Ads, which currently accounts for most of our revenue. Advertising revenue grew 37% YoY in Q3'24, well ahead of GMV, reaching a penetration of 2.0% of GMV, up 30 bps YoY. Q3’24 Results 2
