Down 12% This Year, Nubank Plans a ‘100b Pivot’ And Investors Are Taking Note | NU

Nu Holdings (NYSE:NU | NU Price Prediction) is down 12.73% year-to-date as of March 23, 2026, and trading near $14.70, yet the business underneath looks nothing like a company in trouble. Nubank just printed $895 million in net income for Q4 2025, received conditional OCC approval for a U.S. national bank charter on January 29, 2026, and now serves 131 million customers across Latin America. That gap between price and business performance is exactly what Reddit investors are debating.

The Efficiency Number That Changes the Conversation

Nubank’s Q4 2025 efficiency ratio came in at 19.9%, the first time it has fallen below 20%. That metric measures how much revenue is consumed by operating costs. Most major U.S. banks operate with efficiency ratios well above Nubank’s, and Nubank’s ratio has collapsed from 78% in Q4 2021 to 20% recently. It’s a fully digital model that eliminates branch costs entirely, and its AI credit-decisioning model, nuFormer, delivers a 3x improvement in accuracy over traditional underwriting machine learning.

Full-year 2025 revenue reached $16.3 billion with record net income of $2.9 billion, up from $1.97 billion in FY 2024, while adjusted return on equity hit 33% for Q4.

Bullish Sentiment, but Valuation Remains the Sticking Point

Sentiment on r/stocks has held steady in the bullish range, with scores between 68 and 70 across all tracked periods from Sunday, March 22, through Monday morning. Discussion peaked Sunday afternoon, with 128 comments in a single hour, before tapering overnight. A representative thread captures the debate well: NU Holdings discussion on r/stocks. One commenter noted: “The efficiency ratio dropping to 19.9% is hard to ignore for a bank at this scale.”

Is NU Holdings (NU) still attractive after recent pullback? The efficiency ratio dropping to 19.9% is hard to ignore for a bank at this scale.

Three reasons dominate the bull case:

• Nubank covers 61% of Brazil’s adult population and is expanding in Mexico at 14 million customers (15% of the adult population), with a banking license conversion already approved
• A U.S. national bank charter, conditionally approved by the OCC in January 2026, opens deposit accounts, credit cards, lending, and digital-asset custody in the world’s largest consumer banking market
• Q4 revenue grew 45% year-over-year to $4.86 billion, with net income up 50%

The skeptical case centers on valuation. Nubank trades at a trailing P/E of roughly 25x, versus a banking industry average of roughly 11x. Some analysts have trimmed price targets, with BofA cutting from $18 to $17 and UBS from $18.40 to $17.20, citing a broader de-rating of high-growth financials.

SoFi Offers a Cautionary Mirror

SoFi Technologies (NASDAQ:SOFI) is down 34% year-to-date versus Nubank’s 12% decline, suggesting the re-rating is sector-wide rather than Nubank-specific. Analyst consensus among 16 analysts with buy ratings on NU points to a target of $20.25, above the current trading price. How quickly Nubank converts operational efficiency into American customer acquisition will determine whether the U.S. expansion thesis holds up over the next few years.
