Nu's Q3 revenue strength lifts shares, but credit and capital questions remain

What happened

Nu Holdings reported record third-quarter earnings that beat analyst expectations, driven by strong revenue growth, sending the stock higher. The master report had flagged concerns about rising credit costs and declining Brazil CET1, and the Q3 release may not fully resolve those issues. The beat is consistent with Nu's strong top-line momentum, but investors need to see whether risk-adjusted NIM recovered and whether early-stage delinquencies stabilized after Mexico's bank launch. Until those metrics show clear improvement, the stock remains in a wait-and-see zone, especially after the rally.

Implication

Investors should treat the earnings beat as validation of revenue growth but not yet of balance-sheet health. The key watch items remain Brazil CET1 above 11.3%, risk-adjusted NIM above 9.5%, and NPL 15-90 below 5.0%. If Q3 numbers show those improvements, the thesis strengthens and a buy becomes more compelling. Otherwise, the stock may be overpricing the good quarter relative to the still-unresolved credit cycle.

Thesis delta

The earnings beat is positive but does not alter the WAIT rating by itself. The surge in the stock price reduces the safety margin, and the rebound in revenue was already expected. We need to see the detailed credit and capital data from Q3 before raising the rating; if the stock is now above $17, it may warrant trimming.
