How to read these numbers
Challenge rate is the share of questions that pushed back, pressed for specifics or questioned management’s assumptions. It describes how questions were asked on the calls tracked here; it does not measure whether any view turned out to be right. See how we grade analysts on earnings-call questions.
Rounding. Rates are rounded to whole percentages, so a small share can show as 0% even when some questions were challenging. The count beside each rate is exact; “none of N questions” means no question was challenging.
No questions recorded. “—” means there is nothing to calculate: no questions were recorded for that period on the calls tracked here. It does not mean there was no activity.
Fewer than 3 questions. A company-level rate is withheld when fewer than 3 questions were recorded for that company; the questions are still counted everywhere else.
Small samples. Profiles with fewer than 10 questions are marked Limited sample.
Reporting periods. Questions are grouped by the calendar quarter each company’s fiscal reporting period maps to, not by the date of the call. Periods without a calendar mapping are listed separately under their fiscal label.

Calendar 2026 Q1
you guys were saying that to target at range to achieve 20% efficiency ratio. So now we are below this level
Show response
Lago guided full-year 2026 to ~20%, attributing Q1's 17.6% to roughly 2/3 timing (marketing, real estate) and 1/3 structural AI-driven gains that will continue.
Calendar 2025 Q3
So the question is, looking forward, this level of cost of risk, it seems that is the new level in the next quarters.
Show response
Lago declined to guide on cost of risk, saying Nu manages with a paranoid focus on short-term data and would pull back if asset quality deteriorated.
