StoneCo is a payments and software provider that serves more than 3.5 million small and medium businesses across Brazil. The company brought in 14.15 billion in revenue last year, growing 11% compared to the prior year. After a difficult period of credit losses in 2021, the business has successfully pivoted into a profitable model that bundles payment processing with digital banking and specialized retail software.
The investment thesis on StoneCo is that its transition from a simple payment processor to a full-service financial partner creates high switching costs that competitors cannot easily break with lower prices. While many rivals only offer a card reader, StoneCo integrates deeply into a merchant's daily operations through its Linx software and digital banking accounts. If StoneCo successfully scales its new credit product without repeating past underwriting mistakes, earnings should grow significantly faster than the broader Brazilian economy.
StoneCo is currently a highly profitable business with a dominant position in a growing market, yet its stock is priced like a company in permanent decline. The business has fundamentally improved its risk profile since 2021, and the current earnings power suggests a valuation gap that is hard to ignore.
StoneCo’s stock crashed after a rough period and has stayed low for years. It is down about 84% from five years ago as the company struggled with bad loans. While the business has since shifted to helping small shops manage their money and software, investors remain nervous and the stock price has not recovered.
What does it do?
StoneCo is a growth business that earns money by charging merchants a percentage of every transaction processed through its platform. When a small shop in Brazil sells an item using a Stone card reader, StoneCo takes a small cut (the take rate) and often earns additional fees by paying the merchant for those sales immediately rather than waiting for the standard settlement period. The company also generates recurring revenue through monthly software subscriptions and interest income from its expanding digital banking and credit products.
Where does revenue come from?
The vast majority of revenue comes from financial services, which includes payment processing and banking for Brazilian merchants. This segment accounts for the bulk of the 14.15 billion in annual revenue, supplemented by a software division that provides specialized tools for retail and pharmacy management. All of StoneCo's operations are concentrated in Brazil, making it a pure play on the formalization of the Brazilian retail economy.
Who are its customers?
StoneCo serves over 3.5 million active payment clients, primarily small and medium-sized businesses across every region of Brazil. These merchants rely on StoneCo for everything from accepting credit cards to managing their payroll and inventory. The company also reached a significant milestone in its banking efforts, with millions of active digital accounts now used by its merchant base. By focusing on "hyper-local" service through its proprietary Stone Hubs, the company maintains a physical presence in cities where larger banks often feel distant or bureaucratic.
What gives it staying power?
StoneCo has staying power because it integrates payment processing directly into the software merchants use to run their businesses. Once a pharmacy or clothing store uses StoneCo for its inventory, accounting, and banking, the effort required to switch to a competitor becomes a significant hurdle.
Where is it headed?
StoneCo is focused on becoming the primary bank for its millions of merchants by aggressively expanding its credit and digital account offerings. Management is betting that by using its real-time data on merchant sales, it can underwrite loans more accurately than traditional banks. If successful, this turns StoneCo from a transaction processor into a high-margin financial ecosystem.
The business is demonstrating strong growth as revenue reached 14.15 billion in 2025, an 11% increase over the previous year. This growth is particularly meaningful because it was accompanied by a massive recovery in profitability, with operating income climbing to 7.27 billion. The trend shows a company that has moved past its 2024 struggles and is now successfully monetizing its massive merchant base.
StoneCo produces high-quality earnings, with a net margin of 24.8% that reflects its move toward higher-margin software and banking services. While free cash flow was slightly negative at -0.03 billion in 2025, this was a dramatic improvement from the -4.89 billion seen in 2024. The gap between earnings and cash flow is primarily driven by the company's decision to use its own capital to fund merchant prepayments and its growing loan book.
The balance sheet is managed with a debt-to-equity ratio of 1.29x, which is appropriate for a company that acts as a financial lender. StoneCo carries sufficient capital to support its credit expansion while maintaining a high return on invested capital of 24.8%. This financial structure allows the company to self-fund its growth without needing to return to the equity markets for more cash.
StoneCo is a highly profitable financial engine that has successfully repaired its business model and is now compounding earnings at a rapid rate.
Gross margins reached 74.5% in the most recent periods, proving that StoneCo has significant pricing power in its core merchant market. The company is successfully adding banking and software services to its existing clients without a corresponding increase in its cost to serve them.
The credit portfolio is the single biggest risk, as any spike in loan defaults could quickly eat into the company's reported profits. While current models appear disciplined, StoneCo has a history of underwriting issues that management must prove they have fully solved.
The Brazilian payments market is roughly $600 billion in volume today and is growing at about 15% annually as the country moves away from cash and toward digital payments. The industry is on track to exceed $1 trillion in volume by 2028 as the formalization of the Brazilian economy continues. Pricing power is structural for players who can bundle software, but it is a race to the bottom for those selling only card readers. StoneCo stands as a top-three challenger that is successfully moving up-market to serve more complex businesses.
The Brazilian merchant market is brutally competitive, with over half a dozen well-funded players fighting for the same small business customers. Barriers to entry for simple payment processing are low, which forces long-term pricing power to depend entirely on software and banking integration. This means the industry is slowly consolidating around players who can offer a full financial stack rather than just a piece of plastic.
PagSeguro is the most direct threat, competing head-to-head for the smaller "long-tail" merchants where StoneCo first started. Mercado Pago is also dangerous because it can acquire customers through its dominant e-commerce marketplace, while the big traditional banks like Itau are finally upgrading their technology to defend their territory. Mercado Pago is the most dangerous threat because it controls the largest digital ecosystem in Latin America.
StoneCo is currently holding its ground and expanding its take rate by selling more services to each merchant. The company has maintained a gross margin above 70% despite price wars in the hardware space.
StoneCo's primary source of protection is the switching costs created by its integrated software and banking services. When a merchant uses StoneCo's Linx software to manage their inventory and its digital account to pay their employees, the cost of leaving is too high to justify. This integration is proven by the company's ability to maintain high margins even as hardware prices fall.
The combination of a 24.8% ROIC and 74.5% gross margins proves that StoneCo's advantage is real and not just a result of a good cycle. These numbers are consistent with a narrow moat that is built on deep software integration into the merchant's daily workflow.
The forward-looking verdict is that this moat is strengthening as StoneCo converts more of its payment-only customers into full software and banking users. Software adoption is the single most important signal that StoneCo is becoming more than just a commodity processor.
Operating income grew from 5.88B to 7.27B in one year.
Significant stock buybacks executed at low single-digit P/E multiples.
Management incentives are heavily tied to long-term net income and cash flow targets.
Capital Allocation Track Record
Mateus Scherer Schwening has led a remarkable turnaround by focusing the company on its most profitable merchant segments and repairing the broken credit business. His leadership caliber is evident in the company's ability to maintain a 24.8% net margin while simultaneously growing the merchant base to over 3.5 million. Management has shown excellent strategic judgment by choosing to compete on service and software integration rather than engaging in a destructive price war on hardware.
The thesis is not heavily dependent on any single individual, as StoneCo has built a deep bench of operators across its proprietary "Hub" distribution network. While the founder's influence remains, the company has transitioned to a professional management structure with clear board oversight and independent governance. The main risk is the temperament of the executive team during periods of Brazilian economic volatility, but their track record over the last two years suggests a disciplined approach to risk.
We expect revenue to grow from $15.0B in FY2026 to $18.9B in FY2031 (~5% CAGR), with EPS growing from $10.58 to $17.41 (~10% CAGR). Growth is driven by deeper penetration of integrated software and banking services into the existing small business merchant base. Profitability improves as the company shifts its mix toward high-margin software subscriptions and credit products. EPS Operating margin expected to reach ~54% by FY2031.
Credit expansion using real-time sales data for underwriting. If StoneCo scales its credit book safely, it captures high-margin interest income that traditional banks cannot easily match.
Deepening software penetration across the 3.5M merchant base. Converting payment customers to Linx software users multiplies the revenue per customer while making them nearly impossible to lose.
Market share gains from legacy Brazilian banks. As smaller merchants move away from bureaucratic traditional banks, StoneCo's local hub model captures the shift to modern digital banking.
Brazilian macroeconomic instability and sudden interest rate spikes. A sharp economic downturn in Brazil could lead to merchant failures and a spike in credit losses.
Central bank regulation of payment fees and take rates. Regulatory changes in Brazil could cap the fees StoneCo charges, compressing margins across the entire industry.
Commoditization of payment processing by big tech entrants. If global platforms offer payments as a free add-on, StoneCo's core processing margins would face permanent downward pressure.
Below is our estimate of current and future fair value, with detailed reasoning and assumptions. Fair value is a judgment, not a fact, and other analysts will likely land on different numbers. Use it as one data point in your research, and apply your own discretion in any investing decision.
We use a Forward P/E approach (price-to-earnings applied to next year's earnings) to value StoneCo. It fits this business because StoneCo has transitioned into a consistently GAAP-profitable entity where earnings and return on equity (ROE) are the primary drivers of value, making revenue-based multiples less relevant than they were during the company's early hyper-growth phase.
Our fair value of $212 is derived by applying a 20x multiple to the FY2026 EPS estimate of $10.58. This 20x multiple sits between high-growth ecosystem peers like MercadoLibre (45x) and Nubank (25x) and pure-play processors like PagSeguro (8x), reflecting StoneCo's superior 29% ROE and software integration compared to basic payment peers. The EPS basis of $10.58 is taken directly from the deterministic projection engine, which aligns with the strong Q1 results where EPS reached $6.89.
A 5-year Discounted Cash Flow (DCF) cross-check produces a fair value of $246, which is within 16% of our $212 Forward P/E result. This secondary model uses the deterministic engine's 10% discount rate and a 20x terminal multiple, confirming that the company's current cash flow generation supports a valuation significantly higher than the current market price. The slight disagreement (our P/E value being lower) reflects a more conservative view on the multiple expansion timing given the high 2.24 beta and Brazilian macro volatility.
We're assuming StoneCo successfully matures from a payment processor into a full-service merchant bank. This transition is supported by the Q1 2026 expansion of the credit portfolio by 14% and the rising adoption of "Pix" and banking solutions that create higher switching costs than simple card readers.
We're assuming the cost of risk remains manageable at the bottom end of management's guidance. While interest rates are expected to stay "higher for longer," StoneCo's recent Q1 print showed stable coverage for stage one and two loans, suggesting that the current credit softening is a contained operational challenge rather than a structural failure.
We're assuming the market eventually re-rates the business toward global fintech peers as earnings durability is proven. Currently, the stock trades at roughly 1x its projected FY2026 earnings, a level usually reserved for companies in terminal decline; we assume a normalization toward a 20x multiple as the "banking hub" strategy demonstrates consistent 15%+ EPS growth.
The biggest risk is a severe Brazilian credit cycle that triggers a spike in non-performing loans and forces a massive increase in credit-loss provisions. This would compress the forward multiple from 20x to 8x and potentially cut the earnings base in half, knocking over $150 off the per-share fair value. Watch the "Stage 3" loan coverage ratios and monthly Brazilian central bank data on small-business delinquency for early warning signs.
Bear case ($110): Non-performing loans (NPLs) in the credit portfolio rise above 12% for two consecutive quarters, signaling a breakdown in underwriting; or Brazilian SELIC interest rates remain above 12% through 2027, compressing net interest margins more than the current 250 million real sensitivity suggests.
Bull case ($320): Banking ARPAC (Average Revenue Per Active Client) doubles by FY2028 as StoneCo successfully cross-sells insurance and investment products to 80% of its merchant base; or Cost of risk stabilizes below 300 basis points, allowing the company to accelerate credit expansion without margin dilution.

The market is bullish because StoneCo has successfully transformed into a sticky financial hub for millions of small Brazilian businesses. By bundling payment processing with banking tools and retail software, the company forces competitors to compete against a complete system rather than just a standalone card reader.
Skeptics think that StoneCo's struggle to overcome past credit losses makes its growth far more fragile than its valuation assumes. Critics worry that the pivot to high-margin banking services hides underlying vulnerabilities in how the company manages loans for small merchants during tougher economic cycles.
