MercadoLibre booked a $1,342 million provision for doubtful accounts in the quarter to 30 September, up from $815 million a year earlier, according to its third-quarter results filed with the SEC on 4 November. Income from operations fell 6.5% to $676 million, according to the table in its shareholder letter. By our arithmetic, the provision was 1.99 times operating income, against 1.13 times a year earlier.
The provision is the cost of a lending book the company says reached almost $18 billion, up 62% year over year. Net revenues and financialincome rose 45% to $10,750 million, and net income rose 6% to $448 million.
Business Pill · Operating Leverage
An evergreen Business Engineer explainer on operating leverage, which also works in reverse when costs grow faster than sales. It teaches the general idea only and does not discuss MercadoLibre.
The key insight: MercadoLibre’s provision for doubtful accounts rose to $1,342 million, 1.99 times its $676 million income from operations, up from 1.13 times a year earlier, by our arithmetic.
Update, 4 Nov, 23:07Z: MercadoLibre shares fell in after-hours trading. MercadoLibre’s after-hours price was $1,617.70 at 6:07 PM ET (23:07 UTC) on 4 November, down $122.18, or 7.02%, from its regular-session close of $1,739.88, according to Nasdaq.com. The shares had closed up 4.68% on the day. Nasdaq.com lists an after-hours low of $1,548.36 at 5:07 PM ET, about 11.0% below the close, by our arithmetic. These are after-hours trades, not a close. A trending topic on X put the drop at 10% and called the quarter “mixed”.
In its results, MercadoLibre reported net revenues and financialincome of $10,750 million, up 45% from $7,409 million a year earlier, and net income of $448 million, up from $421 million. Income from operations was $676 million, down from $724 million. Diluted earnings per share were $8.83, against $8.32.
As this piece notes, the provision for doubtful accounts was 1.99 times income from operations, against 1.13 times a year earlier, by our arithmetic.
Total payment volume at Mercado Pago rose 53% to $109 billion and gross merchandise volume rose 38% to $23 billion, both in dollars. Fintech monthly active users reached 93 million, up 29%. The operating margin was 6.3%, which the letter says is “40bps below Q2’26”.
Adjusted free cash flow was $285 million, “even after $503mn of capex and $2.1bn of investment in the expansion of our credit portfolio (partially offset by $1.5bn of fintech funding)”, the letter says. In September the company raised $1 billion in its second investment grade bond issue.
MercadoLibre provision for doubtful accounts, income from operations and net income, July-September 2025 vs July-September 2026, in $ millions, from its Q3 2026 results (Form 8-K Ex. 99.1, 4 November 2026). Percent changes are rounded; the provision-to-operating-income ratio is our arithmetic.

Why the Provision Grows Faster Than the Book
Provisions rose about 65%, a little faster than the 62% growth of the portfolio, by our arithmetic. The letter explains the timing: “we provision for expected losses upfront, on every dollar of that balance as soon as it is drawn”. Interest on the card, by contrast, comes only from users who revolve a balance or pay it off over several months, so “a cohort’s NIMAL starts negative and turns positive as it matures”.
The credit card now makes up 47% of the portfolio, up from 44% a year ago. MercadoLibre calls the card “our largest investment in Fintech”, at almost $450 million over the past 12 months. NIMAL, its net interest margin after losses, was 20.1%, down 1 percentage point, while the 15-90 day NPL ratio was 7.0%, which the letter calls broadly stable.
In Brazil, card cohorts issued from 2021 to 2024 are NIMAL positive and make up more than half of the card portfolio, the letter says, while the 2026 cohort “is in its early, loss-making phase”. Issuance in Brazil reached a record in the quarter.
A Second Way to Read Operating Income
Adding the provision back to income from operations gives $2,018 million, up 31% from $1,539 million, by our arithmetic. That is not a measure MercadoLibre reports. The provision rose $527 million year over year, against a $48 million fall in income from operations, by our arithmetic.
The letter explains the fall in operating margin from the second quarter with two factors. Shipping cut gross margin by 40 basis points quarter on quarter, as more free shipping, energy prices and new capacity weighed. Sales and marketing rose 40 basis points to 11.6% of net revenue after “a tactical decision to invest more in our affiliates program in Brazil”.
What the Letter Says About AI
MercadoLibre says “Our investment in AI grew by almost $30mn QoQ” while usage grew much faster than spend. It is “significantly expanding our use of open-source models”, and its cost per token “is much lower than a year ago, and fell again this quarter”.
The letter gives three operating figures. “Our AI advisor now manages campaigns for 56,000 sellers”, almost four times the number three months earlier. In customer support, “we handle today’s volume with around 7,000 representatives”, and the company estimates it would need a multiple of that without AI. Its fintech assistant Mago “held 19mn conversations in September alone”.
Advertising revenue grew 51% on an FX-neutral basis. The letter says “AI is now central to how we sell ads”, and that Netflix will join Disney, Roku and HBO Max on its connected TV offering from early 2027.
Update, 5 Nov, 07:23Z: MercadoLibre keeps its listings out of outside AI shopping agents, for now. On the third-quarter call on 4 November, chief executive Ariel Szarfsztejn said, according to a transcript published by Benzinga: “But for now, we have decided not to provide our inventory to any external platform.” He said the priority is to build the best agentic experience inside MercadoLibre, drawing on its 27 years of first-party data, and that its own agent is already available to a small portion of users in its three largest markets, with results “early, but promising.”
He described agentic shopping as an opportunity to accelerate the shift from offline to online retail, and said it was too early to share results. Wall St Engine’s post on X summarised the remark at 22:41 UTC.
As we read the letter, the provision line is where the credit card’s timing shows up: losses are provisioned when a balance is drawn, and interest arrives later as each cohort matures.
As we read the statements, the provision rose $527 million while income from operations fell $48 million, by our arithmetic; the company does not report a measure that adds the two together.
MercadoLibre, Q3 2026 shareholder letter
“the faster we issue relative to the size of the mature book, the larger the near-term cost, even when the economics of each cohort are sound.”
Three Implications
FOR THE CREDIT BOOK The portfolio reached almost $18 billion, up 62%, and the card is 47% of it; the 15-90 day NPL ratio was 7.0%, which the letter calls broadly stable.
FOR THE MARKETPLACE GMV rose 38% in dollars, and the letter ties a 40 basis point gross margin hit to more free shipping, energy prices and new fulfillment capacity.
FOR AI COSTS MercadoLibre says its AI investment grew by almost $30 million quarter on quarter while its cost per token fell, helped by a wider use of open-source models.
The framework says: “In the embedding era, value comes from what the software connects to.”
As we read it, MercadoLibre’s letter makes a similar case for its ecosystem: users who both shop and bank with it have an average revenue per user 3-4 times that of single-vertical users, and the same activity feeds its ads business and the underwriting of its credit book. The framework does not discuss MercadoLibre. For the full framework, read The AI Embedding Business Model on businessengineer.ai.
The release does not split the $1,342 million provision between consumer loans, merchant loans and card receivables, so the card’s share of the increase cannot be read from it. The credit portfolio figure is given as almost $18 billion, not an exact number. The AI savings in customer support are the company’s own estimate. The earnings call may add detail.
MercadoLibre’s 10-Q for the quarter was not on EDGAR when we read the filing, so we did not run a risk-factor comparison.

This week’s issue: for two years the AI build-out was priced as a growthstory. This week it started being priced as a credit story.
MercadoLibre grew revenue 45% while income from operations fell 6%. Its provision for doubtful accounts, $1,342 million, was 1.99 times operating income, up from 1.13 times, by our arithmetic. The letter explains that card losses are provisioned upfront and interest arrives later as cohorts mature.
