STNE (StoneCo Ltd.) Analyst Note Date: 2026-06-20 Subject: Structural Setup & Business Fundamentals Review

1. Structural Readiness

State: Forming. Coil Classification: FORMING. Conservative Entry: Not yet defined (awaiting breakout). Aggressive/Pre-breakout Entry: N/A (Setup is forming, not active breakout). Breakout Level: Not yet established (requires price to close above the coil resistance). Current Price: 10.59. Extension: Not applicable (price has not extended from a breakout). ATR Context: Current ATR is 4.7% (High). This indicates elevated volatility, which is within the historical "sweet spot" (4–6%) for structural setups, suggesting sufficient momentum for a potential move but requiring careful position sizing.

2. Thesis Layer

Thesis Classification: TACTICAL. Macro Thesis Status: There is NO named secular thesis attached to this name as of 2026-06-20. Judgment Framework: This name must be judged strictly on setup quality (the structural formation described above) and business fundamentals (operational execution and financial health). Do not invent a macro narrative (e.g., "Brazilian recovery" or "rate cut beneficiary") to force a conviction score. The conviction must derive from the alignment of the forming coil structure with the tangible evidence of business improvement provided in the earnings data.

3. Business Fundamentals

Company Overview: StoneCo Ltd. operates within the Brazilian internet and financial ecosystem, providing payment solutions, e-commerce markets, and credit services to Micro, Small, and Medium Businesses (MSMBs) and Key Accounts. Business Model: The company generates revenue through transaction activities (processing payments, including Pix QR Code transactions) and other services. It has expanded into a credit business, offering secured credit products to deepen merchant relationships and manage risk intensity. Key Evidence (as of 2026-06-20):

• Client Growth: The total active client base reached 4.7 million in Q1 2026, representing a 13% year-over-year increase and a 5% sequential decline (attributed to seasonality and client mix effects).
• Credit Portfolio Expansion: The total credit portfolio grew to BRL 3.2 billion, a 14% sequential increase. Management notes they have recently begun disbursing secured credit products to expand access and reduce risk intensity.
• Revenue Scale: Total revenue and income from continuing operations were reported at 2,572.3 (currency unit implied as millions, likely BRL or USD based on context, though the filing lists 14,153.8 and 12,049.6 for other periods, indicating significant scale).
• Transaction Volume: Net revenue from transaction activities includes all card volumes settled, specifically highlighting Pix QR Code transactions from dynamic and static QR codes.
• Management Guidance: As of the May 19, 2026 earnings transcript, management stated that despite interest rates potentially remaining higher for longer, full-year 2026 guidance remains unchanged.
• Risk Outlook: Management expects the cost of risk to decrease, returning to the mid- to high teens over time.
• TPV Trends: Total Payment Volume (TPV) growth is reported as improving in April.

4. Archetype and Conviction

Archetype: Quality Compounder. Rationale: The name fits the "Quality Compounder" archetype based on the evidence of consistent client base growth (13% YoY), sequential expansion of the credit portfolio (14% sequential), and the strategic introduction of secured credit products to lower risk intensity. The business is demonstrating the ability to scale while managing credit risk in a higher-rate environment. Valuation & Conviction Stack:

• Thesis Strength: Low (No named macro thesis; purely tactical).
• Evidence Quality: High. The earnings transcript and SEC filings provide specific, quantifiable metrics on client growth, portfolio size, and risk management.
• Structural Quality: Moderate/Positive. The ATR of 4.7% suggests a healthy volatility environment for a setup, but the "Forming" status means the structural quality is unconfirmed until a breakout occurs.
• Rerating Potential: Dependent on the successful execution of the credit strategy (secured products) and the realization of the "mid- to high teens" cost of risk target.

5. Invalidations, Strengths, and Gaps

What Would Strengthen the Case:

• A confirmed close above the coil resistance (breakout) with volume.
• Further sequential growth in the active client base beyond the Q1 2026 5% decline.
• Confirmation that the secured credit products are successfully lowering the cost of risk below the mid-teens faster than expected.
• Sustained TPV growth momentum beyond April.

What Would Invalidate the Case:

• A significant deterioration in the cost of risk that pushes it well above the "mid- to high teens" guidance.
• A reversal in the client base growth trend (e.g., sequential decline accelerating beyond seasonal norms).

Gaps in Evidence:

• Specific Guidance Numbers: While guidance is "unchanged," the specific revenue or EPS targets for 2026 are not explicitly detailed in the provided evidence snippets.
• Profitability Metrics: The evidence focuses on top-line growth (TPV, clients) and credit portfolio size, but specific net income or margin expansion figures for the current period are not explicitly quantified in the provided text (only total revenue figures are listed).
• Competitive Landscape: No specific data on market share shifts or competitive pressure from other fintechs is provided in the evidence block.

PRIVATE ANALYST CALL

Judgment: Speculative Confidence: medium Key evidence: 13% YoY growth in active client base to 4.7 million; 14% sequential growth in credit portfolio to BRL 3.2 billion; management guidance unchanged despite higher-for-longer rates; secured credit products launched to reduce risk intensity. Key risks: Cost of risk failing to decrease to mid- to high teens; client base sequential decline accelerating beyond seasonality; structural setup remains in "forming" state with no breakout confirmation; high current ATR (4.7%) implies elevated volatility risk. Sizing hint: Position size should be conservative given the "forming" status and lack of breakout confirmation; treat as a partial setup signal rather than a confirmed trade. Expected path: Management expects cost of risk to normalize to mid- to high teens while credit portfolio expands; if TPV growth continues to improve in Q2, the forming coil structure may resolve to the upside. Expected horizon: 3 to 6 months for the structural setup to resolve (breakout or invalidation).
