NU Nu's Margin Just Compressed for the First Time Since Its IPO. Should That Worry You?

The First Real Test of the Margin Story

Nu Holdings' Form 20-F for the year ended December 31, 2024 confirms the same top-line story every quarter of the year already told: record revenue ($11,517.1 million, up 43.4% year-over-year from $8,029.0 million in FY2023) and record net income ($1,972.1 million, up 91.4% from $1,030.6 million). But the fourth quarter itself - and CFO Guilherme Lago's own words describing it on the call - marks something new in Nu's public-company history: net interest margin (NIM) contracted 70 basis points sequentially to 17.7%, even as net interest income hit a record $1.7 billion (+57% year-over-year FX-neutral). This is Nu's first real margin compression since going public in December 2021, and management named two specific, disclosed causes rather than a vague "market conditions" excuse: lower credit yields from a mix shift toward secured, lower-yield lending (see nu/2024-09 for the personal-lending-versus-credit-card shift first flagged last quarter), and elevated funding costs in Mexico and Colombia, where deposits are still being priced at a premium to benchmark rates to win share fast in two young markets.

That second cause is a real, quantifiable number, not just color: Mexico's deposit base hit $4.5 billion by year-end, a fourfold increase from 2023, and Mexico itself crossed 10 million customers during the quarter (+91% year-over-year) - a genuinely large win. Colombia's checking-account deposits reached $1.3 billion just two quarters after launch, putting Nu among Colombia's top five institutions for individual demand deposits. Both are real evidence the land-grab strategy works. But CEO David Vélez used part of the call to lay out a "Three-Act Story" framing 2025 as "another pivotal year of investment" across all three geographies plus new product verticals - explicit guidance that the margin pressure isn't a one-quarter blip management expects to reverse quickly, it's the deliberate cost of an investment phase they're choosing to extend. Whether that's the right tradeoff is exactly the tension this quarter surfaces for the first time with real numbers behind it (see Target Valuation Range).

The Prescription

Nu should keep running the Mexico and Colombia land-grab exactly as disclosed - a fourfold deposit increase in Mexico and a top-five Colombian deposit ranking in two quarters are the kind of fast, capital-efficient customer acquisition wins that took years to achieve in Brazil, and management's own framing (deposit rates "reducing... sequentially" as each market matures) shows the glide path is deliberate, not open-ended. The mid-to-long-term answer to the NIM question that Lago gave on the call - shifting funds from cash into credit as the loan-to-deposit ratio normalizes - is the correct lever: Nu is sitting on more deposits than it's lending out relative to its balance sheet size, and that gap is genuine, controllable upside rather than something the market has to simply wait out.

What Nu should stop doing: treating NIM compression as background context buried inside the operating-metrics discussion rather than naming it as its own explicit line item with a target range. This is the first quarter margin actually moved the wrong way, and a company whose entire investment thesis has been "growth without margin sacrifice" owes shareholders a specific number - a NIM floor it's targeting, or a quarter by which Mexico/Colombia funding costs should stop dragging the group average - rather than a general assurance that "balance sheet optimization will be the primary driver of future NIM." A vaguer version of the same reassurance, repeated every quarter without a number attached, is exactly the kind of soft guidance that stops meaning anything after enough repetitions.

Operational Metrics

• Total customers: 114.2 million (+22% YoY), of which 94.9 million active customers (+22% YoY).
• Monthly activity rate: 83.1%, roughly flat year-over-year, slightly down sequentially from Q3's 83.6%.
• Mexico: crossed 10 million customers during the quarter, +91% YoY, and $4.5 billion in deposits (a fourfold increase from 2023).
• Colombia: $1.3 billion in consumer deposits, two quarters after its checking-account launch - among the country's top five institutions by individual demand deposits.
• Net interest margin: 17.7% (Q4 2024), down 70bps sequentially - the metric at the center of this quarter's story (see above).
• FY2024 Annualized ROE^»: 28% (Nu's own non-IFRS calculation, disclosed in the earnings presentation rather than the audited statements themselves).

Beyond the Usual

Nu Quietly Wound Down Its Crypto Trading Feature

In September 2024, Nu discontinued the liquidity pool feature that let customers buy and sell "Nucoin" - its crypto-loyalty token - and repositioned Nucoin instead as part of a new points-based loyalty program still under development. The wind-down wasn't free: Nu recorded a $40 million charge (primarily marketing expense tied to the repositioning) plus an $8 million impairment on capitalized intangible assets tied to the liquidity pool. Separately, the SEC rescinded its crypto-safeguarding accounting guidance (Staff Accounting Bulletin 121) and replaced it with SAB 122 in January 2025; Nu adopted the new rule retrospectively as of December 31, 2024, which removed a safeguarding-obligation liability and matching safeguarding asset related to crypto assets it held in custody for other parties from its balance sheet. Two separate crypto-related items landing in the same annual filing - a real product wind-down and an accounting-standard change - is a reminder that Nu's crypto exposure, while never a headline business line, was real enough to leave a $48 million mark on the income statement when it was scaled back.

A Director's Company, Still Undisclosed by Name

The related-party footnote first flagged in nu/2024-09 recurs in the annual filing essentially unchanged: Nu's Q2 2024 commercial arrangement with "a company where one of its Directors serves as CEO" is disclosed again, still without naming the counterparty, the cash incentive's size, or the specific conditions attached to it - only a $1.8 million net related-party liability appears in the year-end table. A single quarter's ambiguity is understandable; the same footnote persisting into the audited annual filing without added specificity is worth continuing to watch.

Nu Became a Venture Investor in an African/Southeast Asian Neobank

On December 12, 2024, Nu made a minority investment as lead investor in Tyme Group's Series D funding round - a digital bank operating in South Africa and the Philippines via a hybrid model of app-based banking plus physical kiosks and retail partnerships. The stake shows up on Nu's balance sheet as a new $99.4 million "Investments in associates" line, its first appearance ever on Nu's consolidated statement of financial position. It's a genuinely notable strategic signal: Nu, a business built on cracking Latin American underbanking, is now putting capital behind someone else's attempt to do the same thing in different emerging markets, rather than only expanding its own footprint organically.

A Real, if Small, Development-Finance Credit Line for Colombia

Nu's Colombian subsidiary signed a 3-year, up-to-$150 million credit facility with the U.S. International Development Finance Corporation (DFC) on September 27, 2024. It's a modest number next to Nu's ~$50 billion balance sheet, but it's a concrete, dollar-denominated funding source for the newest and smallest of Nu's three markets - and a DFC facility specifically (rather than a commercial credit line) signals the U.S. government sees Colombian financial inclusion as a development-finance priority worth backing directly.

Contingent Litigation Stayed Small and Roughly Flat

Total possible-loss (not probable, not accrued) civil and labor lawsuits were approximately $20.4 million combined at year-end 2024 (versus about $26.5 million at year-end 2023) - a small, declining number relative to Nu's now-$49.9 billion balance sheet.

What Management Emphasized on the Call

Vélez opened by naming 2025 as the year Nu executes a deliberate "Three-Act Story": deepening principality (customers using Nu as their primary bank) in Brazil, Mexico, and Colombia; expanding into new product verticals; and laying groundwork for what he called a long-term "Global AI-Driven Digital Banking Model." Lago's prepared remarks then walked through the NIM compression in detail rather than glossing over it - crediting it explicitly to the secured-lending mix shift and Mexico/Colombia funding costs, and reiterating that "regardless of interest rate trends," shifting funds from cash into credit as the loan-to-deposit ratio normalizes is the mid-to-long-term lever Nu is counting on. On the crypto wind-down and the Tyme investment flagged in Beyond the Usual, management didn't address either on the call - both are the kind of balance-sheet and portfolio-strategy items that surface in the filed statements rather than in prepared remarks unless an analyst asks directly, and none did this quarter.

Stock Price: A Round Trip, Then a Pullback

Nu's share price closed 2024 at $10.36, up from $4.07 at the end of 2022 - a roughly 155% two-year gain that clears this project's threshold for its own section. But the shape of that move matters as much as the endpoint: the stock hit a 2024 high of $15.09 in October, then fell to $12.53 by late November and $10.36 by year-end - a roughly 31% pullback in the final two months of the year, arriving in the same window this quarter's NIM compression became visible in the numbers. That timing doesn't prove causation (broader emerging-market and rate-sensitive-financial repricing was also underway into year-end 2024), but it's consistent with a market that had been pricing Nu as a margin-immune growth story starting to price in the possibility that it isn't.

Target Valuation Range

Fair-value read: today's $49.9 billion market cap (~23x trailing Adjusted Net Income) is a reasonable price for the growth rate - down from the ~30x implied three months ago in nu/2024-09, as the market started pricing in near-term NIM-compression risk rather than assuming a smooth reversal.

With 4,818,658,640 total shares issued as of December 31, 2024 and a $10.36 closing price:

Market cap → enterprise value	FY2024
Share price (period-end)	$10.36
Shares outstanding	4,818,658,640
Market capitalization	~$49.9B
Total liabilities	n/a (net cash basis used)
Less: cash and equivalents	$9,185.7M (vs. $1,730.4M borrowings and financing)
Enterprise value	~$42.4B

Market cap is down from the ~$65.6 billion implied at the end of Q3 2024 (see nu/2024-09), almost entirely on the stock-price pullback described above rather than a change in share count.

Peer-multiple sanity check	Q3 2024	FY2024	Change
Enterprise value	~$59.5B	~$42.4B	✅ down
EV/Revenue	~5.1x (annualized run-rate)	~3.7x (full year)	✅ down
P/E	~29.6x (annualized run-rate) / ~27.7x (Adjusted Net Income)	~25.3x (TTM) / ~22.6x (Adjusted Net Income)	✅ down
P/B	~8.6x	~6.5x	✅ down

A full DCF is more defensible with a genuine full year of audited profitability behind it, but the honest read is that this filing raises the stakes on the assumption a DCF has to make, rather than resolving it: Mexico and Colombia's NIM drag is disclosed as temporary, self-correcting through balance-sheet optimization and rate normalization - but that's management's own framing, not yet three data points confirming the reversal. A reverse-DCF lens is more honest here: at a $49.9 billion market cap against $2.2 billion of trailing Adjusted Net Income (22.6x), the market is pricing in continued 20%+ earnings growth for several more years without demanding proof the NIM compression actually reverses first. That's not an unreasonable bet given Nu's track record of hitting its own growth targets - but a reader should be explicit with themselves that the multiple has already fallen from Q3's ~30x to today's ~23x specifically because the market started pricing in the risk that the bet doesn't pay off on schedule, and the next couple of quarters' NIM trend (not the growth numbers, which remain excellent) is the thing to actually watch.
