Nu Holdings now expects its full-year efficiency ratio to land between 19% and 19.5%. Chief Financial Officer Rob Livingston said, "We are seeing significant benefits from AI helping us with our capacity and productivity." The bank got a boost from higher revenue and a slower pace of hiring lately.

Nu Holdings, which has over 140 million clients and in September began ​expanding beyond Latin America, now expects its full-year efficiency ratio, ​which measures how much a bank has to spend ⁠to generate revenue, to land between 19% and 19.5%, below a ​previous expectation of around 20%.

"The biggest thing is that our pace of ​hiring was a little bit slower than we expected," Chief Financial Officer Rob Livingston told Reuters. "We are seeing significant benefits from AI helping us with our ​capacity and productivity, and so we slowed down our hiring," he ​said.

Livingston said Nubank's back-to-office policy, announced last year, as also rolling out slower than ‌initially ⁠planned as the company is opening new offices in several cities, while stronger-than-expected revenue also boosted efficiency prospects.

Nubank reported $1.09 billion in net income for the July-September quarter, up 31% from a year earlier on ​a currency-neutral basis ​and matching the ⁠Visible Alpha consensus.

Revenue also came roughly in line with market expectations at $6.26 billion, a 37% boost. The ​90-day delinquency ratio rose to 7.3% from 6.7%, a ​climb ⁠the CFO attributed mostly to seasonal effects and an increase in risk between late last year and early this year.

"We're not seeing any evidence ⁠of ​broad-based exogenous worsening in our portfolio," he ​said. "The increase is entirely due to management decisions and timing that we were anticipating," ​he noted.
