Business type: Capital scale-up · scaling but economically observable

The business does not meet the quality standard for its economic type.

Investment view

At $1,885.73, MELI requires a 18% five-year revenue growth rate to justify its enterprise value — less than the business already delivers, at 39%.

The value rests on an exit multiple of 18.0x and a terminal operating margin of 13%. Move any one of them materially and the conclusion moves with it, which is why the required-versus-demonstrated test above carries more weight here than the point value.

The strongest argument against this view: the consumer credit book, principally the credit card.

Risk and sell discipline

Impairment case

The consumer credit book, principally the credit card. This is a permanent-loss mechanism, not a multiple forecast. MELI's managed credit portfolio nearly doubled year over year to $14.6bn (CFO prepared remarks, Q1'26) against $7,281m of shareholders' equity - net loans receivable alone are $10,735m, or 1.47x book equity. The card is now the fastest-growing slice: 2.7m cards issued in Q1'26, card TPV +90% YoY, and the vintage is being written into a LatAm consumer whose repayment behaviour through a full cycle has not been observed at this scale. THAT IS A CASH LOSS, not A MARK, and it is not recoverable by waiting. It would also force origination growth to a halt for 12-18 months, removing the engine behind 49% revenue growth, so the earnings base resets at a ~6-7% EBIT margin on a materially slower top line.

Estimated probability 20%, against the 30% level at which the position would be resized. It sits within that level.

Fundamental invalidation

Falsifiable and fundamental — not one of them is a price condition.

Price-based risk trigger

A daily close below $1,659.44 triggers an immediate review of the thesis and pauses additional buying. It is not an automatic sell unless a separate fundamental invalidation condition has been breached.

Upside sell discipline

On approach to the $2,525.00 target the case is reviewed rather than added to; a target reached is a reason to re-examine the position, not to hold it by default. The position is trimmed once forward expected return falls below 0% net of costs, because the capital has a better use elsewhere in the book.

Investment criteria

CriteriaStatusInvestment meaning
QualityNot metIs the business worth owning under its declared economic type?
ValuationMetIs the operating path required by today's price achievable?
LiquidityMetCan the intended position be built and exited in the right vehicle?
DownsideMetThe consumer credit book, principally the credit card.

CatalystNot determinedIs there a dated event that resolves the disagreement? Not established on the evidence on file.
ConsensusNot determinedIs the house-versus-Street disagreement identified and quantified? Not established on the evidence on file.

Quality, valuation and liquidity can prevent a position on their own. The remaining four inform timing, sizing and monitoring, and never reject an investment by themselves.

Bottom line

The strongest case for mispricing is that the business already delivers +20.6 percentage points more growth than the price requires. The most important unresolved uncertainty is the permanent-loss mechanism: the consumer credit book, principally the credit card. The next evidence that should change the portfolio decision is the next scheduled results, or a daily close below $1,659.44, which forces an immediate review.
