Understanding Mercado Libre’s Q1 through the lens of Time Arbitrage
Mercado Libre Q1 Deep Dive: Why lower margins may create Long-Term Value
Markets are obsessed with the next quarter. Management teams know it, analysts know it and investors certainly feel it every earnings season. Public companies are constantly judged on short term margin progression, near term guidance and whether results came in a few percentage points above or below expectations. In that environment most companies optimize for short term targets, often associated with their bonus target they need to hit.
The willingness to sacrifice today’s profitability for a stronger position years down the road often is low and surprises people if it happens. That disconnect creates what I would call “time arbitrage”: the opportunity that emerges when a company operates on a longer time horizon than Wall Street is willing to tolerate.
It usually goes like this: A business enters a heavy investment phase, margins compress, free cash flow weakens (or turns into cash outflows) and the market immediately assumes that something is structurally broken. In reality, management may simply be optimizing for a much larger prize further out in time.
We are seeing this dynamic play out once again with Mercado Libre. After years of impressive profitability expansion, the company has ramped investments back up across logistics, credit and commerce infrastructure. The response from the market was as usual: concerns about margins, fears that peak profitability has already been reached and a sharp selloff after earnings. Yet this is the same company that built one of the strongest ecosystems in Latin America precisely because it repeatedly prioritized long term dominance over short term optics. I understand the skepticism for an unproven management team, but MELI literally did this same thing multiple times in the past.

A similar idea can be seen in Stevanato Group. While parts of the industry remain cautious, Stevanato continues investing aggressively into high quality manufacturing capacity to satisfy demand for specialized value-added solutions. In the short run, these decisions pressure returns and create excess costs before demand fully materializes. As a family business they focus on longer periods and capacity constraints often become competitive advantages there. Companies that invest through uncertainty are frequently the ones best positioned when demand eventually catches up.
The challenge is that time arbitrage is psychologically difficult to exploit, even when the opportunity seems obvious in hindsight. Buying into an investment cycle means accepting weaker current margins, lower earnings visibility and often multiple quarters of negative sentiment. More importantly, it requires a very high level of trust in management. Investors need confidence that capital is being allocated intelligently, that the moat is actually widening, and that the long term payoff will justify the temporary pain.
The market often struggles to distinguish between deteriorating economics and deliberate reinvestment. For patient investors, that gap can become one of the most powerful forms of edge available.
In many cases, time arbitrage also creates a toxic mix that screens terribly on the surface: slowing growth, rising leverage, and valuation multiples that suddenly look difficult to justify. Stevanato Group is a good example. Heavy capacity investments pressure near term returns while debt levels rise ahead of future demand, even as the stock may still trade at what appears to be a demanding multiple. For quantitative screens or short term investors, that combination often looks like a clear avoid. Fortunately, we aren’t short term investors and claim to pounce on opportunities like that. When the market focuses too heavily on near term financial targets, it can miss that the underlying competitive position may actually be strengthening beneath the surface. New bear cases will emerge, calling the shrinking margins structural instead of self-induced and as we all know bears usually sound pretty smart at the time (we love when the status quo is questioned).
Today I want to dive into Mercado Libre’s latest earnings report and whether or not this is a time arbitrage opportunity. I will dissect the shareholder letter and earnings call and layer my own opinion on top. Finally, we’ll look at a valuation exercise on MELI.
Q1 earnings sent MELI down around 12%, following two main data points:
Revenue growth accelerated to 49%, marking the forth quarter of revenue acceleration in a row. At their size of ~$30 billion in revenue these growth rates are almost unprecedented. This strong growth was driven across the board through gross merchandise value (GMV) up 42%, items sold up 47%, total payment volume (TPV) up 50% and credit portfolio up 87%. Active buyers grew 26% and they bought 16% more items compared to last year. Fintech monthly active users (MAU) grew even faster at 29%. We can see that this was a blowout quarter taking lots of market share….but
margins collapsed considerably with operating margins down 600 bps to 6.9% and net income margin down 360 bps to 4.7%. Wall Street now expects these margin issues to be structural and a range of downgrades have followed and more will follow in the coming days surely. Let’s dissect why margins are crushed, if it’s structural and what I personally think about MELI at these prices.
I can highly recommend you to read the shareholder letter, as it brought a lot of good insights. I’ll go through what I found most interesting, but I’m sure there are other interesting bits there too.
Before that let’s quickly assess the main worries the market has:
New competition from Amazon, Shopee (Sea limited) and Teemu (PDD) will crush margins structurally. Free shipping is a defensive move and not offensive.
Credit is becoming more risky and changes the risk profile of the business.
MELI will have structurally lower margins as they’ll always invest into new business and never showing real cash flows.
New buyer cohorts joining since the threshold change are purchasing more items across a broader range of categories with higher retention than older cohorts. We believe the data is clear: we are expanding the market, deepening engagement and strengthening our platform.
Lowering the free shipping threshold in Brazil so far is showing strong results, as these new cohorts are behaving differently, because they use the platform more often incentivized by free shipping. MELI thus is reaching new consumer segments. Not all of these new users are instantly profitable (shipping costs on lower orders are expensive), but over time purchasing from 3P sellers and activating ad revenue makes these investments worth it.
Free shipping has always been a long-term investment in user behavior, not a short-term promotional tool. When we launched it in 2016, it took time for unit economics to improve enough to offset the investment – but the compounding impact on engagement and scale validated the decision. Today, like in 2016, the signals we see give us confidence: user behavior is responding as we expected, and unit shipping costs are falling faster than we had anticipated. These are the two most important signals at this stage.
I think the market ignores that MELI did experiments like this in the past with great results. They know the playbook (Amazon anybody?) and are executing it again to reach new users. It’s not like MELI’s management team is flying blind here. Even more importantly, it introduces users into the ecosystem, where they’ll over time adopt more services like credit, speaking of which…
Our confidence to invest in the credit card is built on predictable, consistent and attractive payback periods. It is one of our most powerful ecosystemic tools, turning millions of marketplace-only users into active fintech users too. The credit card increases marketplace conversion, GMV per user, and transactions across the ecosystem. This is the cross-sell flywheel at work.
So we established that credit activates more users and is a strong tool, but how will profitability and risk develop over time? We’ll get to that later. First let’s discuss what’s on everybody’s minds: AI and how MELI uses it.
We rolled out our first AI-powered search experience in our marketplace in Q1’26, shifting the architecture away from keywords and rebuilding it around LLMs. In Brazil and Mexico, the improvement in product relevance led to uplifts in conversion and click-through-rate for sponsored listings, both of which represent incremental revenue.
This sounds very exciting. I sometimes am in the situation, where I know what I need to do, but not how a tool is called. Having a new way to search the marketplace sounds like a great new initiative that’s already generating new revenue. Another interesting use case for AI mentioned was productivity gains. MELI only grew its tech headcount by 8% (from 2025 hiring), while productivity KPIs are growing 7-10x faster. Engineers now can use their time with higher value tasks (i.e. developing new features instead of writing documentation) and MELI rolled out Claude Cowork to 31k employees, making them one of the earliest adopters.
Advertising is a large and fast-growing opportunity as traditional channels still account for half of the market in Latin America versus just a quarter in the US.” - MELI grew 4x the market in 2025 with 63% FXN ad growth.
Digital ad penetration is still low in LATAM, which means that MELI has a long runway to grow as this transition happens on top of taking share of the market (which they are doing if they grow 4x the market pace).
Asset quality remained solid, with the 15-90 day NPL of 8.0% broadly stable YoY, reflecting the continued strong performance of our underwriting models and our prioritization of risk management. NIMAL of 17.8% was lower QoQ, which follows the normal pattern of seasonality, while the 4.9ppts YoY decline was driven by the higher mix of the lower-spread credit card and some compression of spreads in Brazil due to higher provisions. While the financial system in Argentina is seeing rising delinquency, our 15-90 day NPL fell sequentially in Q1'26 while spreads increased. This demonstrates the strength of our underwriting and our agility.
To understand this topic better, I want to view this tweet here: People got scared after the news that MELI is increasing loan duration by 60% got out! 60 per cent, that’s a lot and surely more risky! If we put it into perspective, MELI had extraordinarily short term loans before. Even after going up to 8 months, they are far below what banks and peers offer. This allows them to penetrate new customer cohorts that are looking for longer duration loans. They are constantly learning and feeding their risk models with more data about purchasing behavior from users shopping on Mercado Libre and using Mercado Pago to pay inside and outside the MELI ecosystem. This self reinforcing flywheel shows up in flat NPL (non performing loans) while they are rapidly growing the business.
People point out that the NPLs are higher than peers, but that’s a calculated bet if we consider that they are targeting customers that haven’t gotten credit from other sources yet, because they can’t model their risks (MELI can because of their user data). NPL only matters in combination with the terms of the loans. MELI charges high enough interest rates to compensate for the risk, shown in the NIMAL (net interest margin after losses) margin of 17.8%. Most peers only report NIM margins, so losses aren’t subtracted from it. While NIMAL for MELI shrunk considerably it’s fine for two reasons:
17.8% is still a very high margin and I expect it to trend closer towards 12% over time as the market matures.
The speed of loan originations is a headwind to NIMAL, because you need to assume the provisions for potential bad debt right as you originate the loan, while the first repayments and interest payments come in months later. A growing credit business always has front loaded accounting noise. Competitor Nu recently shared a podcast on exactly this topic, which I highly recommend.
Overall, we need to continue monitoring the situation. It’s fine as long as we don’t see a strong deterioration in NPLs. Fortunately, if the situation gets bad MELI can slow down originations and with 8 months of duration, it’s lower risk than what customers have with long duration loans.
