Executive Summary / Key Takeaways

• Margin Inflection at Ipiranga: The "Carbono Oculto Operation" represents a historic regulatory crackdown on Brazil's BRL 29 billion illegal fuel market, driving volume recovery and margin stabilization in Q3 2025 after years of compression from tax evasion and fuel adulteration.
• Hidrovias as Growth Engine: Ultrapar's BRL 1.8 billion investment to acquire control of Hidrovias do Brasil is its largest capital allocation in a decade, positioning the company to capture Brazil's agribusiness logistics supercycle with waterway transport that is 40-60% cheaper than road alternatives.
• Storage Moat Expansion: Ultracargo's 34,000 m³ Santos terminal expansion and new Palmeirante operations create a high-margin, asset-backed revenue stream directly tied to Brazil's growing agricultural exports, with capacity utilization set to improve as agribusiness volumes accelerate.
• Capital Allocation Discipline: Management is balancing aggressive growth investment (BRL 2.5 billion CapEx, 60% for expansion) with substantial shareholder returns (BRL 1.09 billion dividend, 25 million share buyback), while maintaining comfortable leverage at 1.7x EBITDA and targeting 20% ROIC.
• Undervalued Transformation: Trading at 7.7x P/E, 0.16x sales, and an 8% dividend yield, UGP's valuation fails to reflect the structural improvement in fuel sector regulation, the earnings contribution from Hidrovias consolidation, and the defensive moats in storage and LPG distribution.

Setting the Scene: Brazil's Energy Infrastructure Backbone

Ultrapar Participações S.A., founded in 1937 and headquartered in São Paulo, has evolved from a regional LPG distributor into Brazil's most diversified energy, mobility, and infrastructure platform. The company operates across four core segments: fuel distribution through Ipiranga (Brazil's second-largest fuel retailer), LPG distribution via Ultragaz (17% market share), liquid bulk storage through Ultracargo (largest independent operator), and since May 2025, waterway logistics via Hidrovias do Brasil.

This diversification is not accidental—it is a strategic response to the inherent volatility of Brazil's fuel distribution market, where margins have been systematically eroded by illegal practices including naphtha adulteration, tax evasion, and biodiesel blending non-compliance. The fuel sector's BRL 29 billion annual loss to irregularities created a structural disadvantage for compliant players like Ipiranga, which saw recurring EBITDA decline 6% in 2024 despite volume growth. The company's response has been to build parallel moats in logistics and storage, where regulatory barriers, asset intensity, and customer switching costs create defensible, high-margin revenue streams.

The investment case today centers on a confluence of three factors: regulatory enforcement finally tilting the competitive playing field, the accretive integration of Hidrovias creating a new earnings engine, and valuation that prices the company as a stagnant distributor rather than an integrated infrastructure platform.

Strategic Transformation: Beyond Fuel Distribution

The Hidrovias acquisition fundamentally alters Ultrapar's growth trajectory. The BRL 1.8 billion investment for a 42% stake, followed by a BRL 1.2 billion capital increase to secure majority control, represents management's conviction that waterway logistics will capture disproportionate value from Brazil's agricultural export boom. Brazil's National Agribusiness Logistics Plan explicitly prioritizes river transport to relieve congested highways and rail systems, creating a 5% CAGR volume growth opportunity through 2030.

This shift is significant because waterway transport costs 40-60% less than road for bulk commodities like soybeans, corn, and iron ore. Hidrovias operates the critical Paraguay-Paraná and North corridors, giving Ultrapar control over infrastructure that cannot be easily replicated. The subsequent sale of Hidrovias' cabotage operation for BRL 715 million demonstrates management's discipline—exiting non-core, lower-margin activities to focus on the core waterway business while deleveraging.

The Witzler acquisition (BRL 124 million) and the pending Virtu LNG logistics stake (BRL 102 million) signal a parallel push into new energy solutions. Ultragaz's new energy segment already contributes 5% of EBITDA and is growing, with biomethane and BioLPG offering higher margins than traditional LPG distribution. The Pecém terminal approval, in partnership with Supergasbrás, creates a strategic import hub that improves supply security in Brazil's Northeast and North regions, where LPG demand is growing fastest.

This implies that Ultrapar is transitioning from a cyclical fuel distributor to a structural growth story tied to Brazil's agricultural export capacity and energy transition. The capital intensity of these investments is offset by the defensive moats they create—terminals, waterways, and import infrastructure have 20-30 year asset lives with high barriers to entry.

Segment Deep Dive: The Four Pillars

Ipiranga: Margin Recovery in Progress

Ipiranga's Q3 2025 results mark the first tangible evidence that regulatory enforcement is working. Volumes grew 1% year-over-year, with the Otto cycle (gasoline) accelerating in September following the Carbono Oculto Operation launch in August. Recurring EBITDA of BRL 892 million was down 5% versus Q3 2024, but this represents a significant improvement from the 13% decline in Q2 and 27% decline in Q4 2024.

This improvement is crucial as the single-phase taxation of hydrated ethanol for PIS/COFINS, implemented in May 2025, eliminates a key tax arbitrage used by irregular players. The tax solidarity principle in São Paulo, which makes resellers jointly liable for unpaid state taxes, has already led to a 2.9 percentage point decline in unlawful companies' market share in 2024. Leonardo Linden, Ipiranga's CEO, emphasizes that "share is a consequence of efficiency," indicating the company is prioritizing profitable volume over market share gains in low-margin spot markets.

Cash generation tells the real story: BRL 1.453 billion in Q3 2025, more than double the prior year, driven by working capital optimization and inventory management. The company ended Q3 with 5,812 service stations, down slightly from 5,860 in 2024—a deliberate pruning of low-volume locations to improve network profitability.

Regarding risks and rewards, Ipiranga's ROIC is not yet at the 20% target, but management expects Q4 2025 profitability similar to Q3, suggesting the bottom is in. If regulatory enforcement sustains, Ipiranga could return to 2016-2017 margin levels, representing 30-40% EBITDA upside from current levels.

Ultragaz: Defensive Cash Generation

Ultragaz delivered BRL 463 million in recurring EBITDA in Q3 2025, up 3% despite a 6% volume decline. This margin expansion reflects inflation pass-through, improved bulk segment efficiency, and new energy contributions. The LPG market faces structural headwinds from electric cooking adoption, but 91% of Brazilian households still use LPG, and the "Gás do Povo" government subsidy program could boost volumes by 5% over five years if restrictions lift.

Ultragaz serves as a cash cow funding growth elsewhere. Its 17% market share, combined with Petrobras ' 89% production dominance, creates a stable oligopoly where pricing discipline is rational. The Witzler acquisition adds electricity trading capabilities, diversifying revenue beyond LPG. The Pecém terminal creates a logistics moat that independent distributors cannot replicate.

Consequently, while LPG volumes may stagnate, EBITDA can grow through mix shift to higher-margin bulk and new energy solutions. This segment provides the financial stability to fund Hidrovias integration and Ipiranga's margin recovery.

Ultracargo: Capacity Expansion Meets Agribusiness Boom

Ultracargo's Q3 2025 EBITDA of BRL 134 million was down 20% year-over-year, but this reflects temporary headwinds: lower fuel import demand (impacting Santos, Itaqui, and Suape) and pre-operational costs at Palmeirante. Average installed capacity grew 3% to 1.097 million m³, with the Santos expansion adding 34,000 m³ in October 2025 and Palmeirante's railway branch connecting to the Itaqui port.

This positions Ultracargo well, as Brazil's agribusiness exports are projected to grow 5% annually through 2030, requiring expanded port capacity. Ultracargo's terminals are strategically positioned to capture this growth, with tariffs that adjust for inflation and spot market premiums. The Rondonópolis expansion (22,000 m³ by 2026) and Suape capacity increase (40,000 m³ by 2028) position the company to double storage revenue by 2027.

Current utilization is depressed by fuel import weakness, but agribusiness volumes are accelerating. As Palmeirante ramps up and Santos reaches full utilization, EBITDA per cubic meter should normalize to historical levels, driving 15-20% segment EBITDA growth in 2026.

Hidrovias: The Hidden Gem

Hidrovias' Q3 2025 recurring EBITDA of BRL 361 million was more than double the prior year, driven by 30% volume growth in the South corridor as navigation normalized. The North corridor also showed improvement, with tariff adjustments and better mix. The sale of the cabotage operation for BRL 715 million reduces net debt by 0.3x-0.4x EBITDA and allows management to focus on core waterway operations.

Hidrovias' EBITDA is seasonal, peaking in Q2-Q3 with crop flows, but the baseline is now established at BRL 350-360 million per quarter. This represents a BRL 1.4-1.5 billion annual EBITDA contribution to Ultrapar, nearly doubling the company's pre-acquisition earnings power. The business has 70-80% EBITDA margins due to its asset-light model (operating concessions rather than owning vessels).

The integration challenge lies in Decio Amaral, the new CEO, delivering on operational efficiency, yield optimization, and administrative cost reduction. Ultrapar's shared services unit can reduce overhead by 10-15%, while tax optimization and debt refinancing can lower financial costs. If executed, Hidrovias could contribute BRL 1.6-1.7 billion in EBITDA by 2026, representing 40% of Ultrapar's total.

Financial Performance: Evidence of Strategic Execution

Ultrapar's consolidated Q3 2025 adjusted EBITDA of BRL 1.9 billion (27% growth) and recurring EBITDA of BRL 1.8 billion (18% growth) demonstrate that the diversification strategy is working. Net income grew 11% to BRL 772 million despite BRL 258 million in financial expenses from Hidrovias consolidation.

Operating cash generation of BRL 2.1 billion was nearly triple the prior year, funding BRL 326 million in dividends and reducing leverage from 1.9x to 1.7x.

The capital allocation framework: Rodrigo Pizzinatto, Ultrapar's CEO, has been explicit: "We are going to try to look up for companies and projects that have similar characteristics to what we found in Hidrovias... If we don't come across good projects, that's okay, we just increased dividend sharing." This creates a clear value proposition: either management deploys capital at 20% ROIC, or returns it to shareholders.

The BRL 2.542 billion 2025 CapEx plan (60% for expansion) is front-loaded, with Ipiranga receiving BRL 1.366 billion for rebranding and logistics, Ultragaz getting BRL 480 million for new energies, and Ultracargo investing BRL 673 million in terminal expansions. Actual spending may be 10% lower due to project timing, suggesting disciplined capital deployment.

Balance sheet strength: Net debt of BRL 12 billion is manageable at 1.7x EBITDA, with 73% denominated in BRL, reducing FX risk. Ipiranga's recent BRL 1 billion debt raise at 106% of CDI is below Ultrapar's average cost, indicating improving credit profile. The company has BRL 3.6 billion in committed credit lines, providing liquidity for opportunistic acquisitions.

Competitive Context: Positioned for Advantage

Ultrapar's multi-segment structure creates competitive advantages that pure-play fuel distributors cannot match. Against Vibra Energia (VBBR3) (24% fuel market share), Ultrapar's Ipiranga holds 20% but generates superior margins through its integrated AmPm convenience stores (1,460 locations with 10% same-store sales growth) and Km de Vantagens loyalty program. Vibra's net margin of 1.00% and operating margin of 2.72% trail Ultrapar's 2.13% and 3.86%, respectively, reflecting Ultrapar's better mix and operational efficiency.

Versus Raízen (RAIZ4): While Raízen leads in biofuel production, its negative 3.89% net margin reflects commodity price volatility and high capex. Ultrapar's distribution-focused model avoids upstream risk, generating more stable cash flow. Raízen's 0.57% ROA is far below Ultrapar's 6.99%, demonstrating superior capital efficiency.

Versus Petrobras (PBR): As the dominant supplier (89% of LPG production), Petrobras controls pricing but has limited retail presence post-Vibra spin-off. Ultrapar's independence allows faster innovation in digital services (Abastece Aí app) and customer experience, while Petrobras' bureaucracy limits agility. Petrobras' 15.77% margins reflect upstream integration, but its 0.88 debt-to-equity ratio and state-mandated pricing constraints create vulnerabilities that Ultrapar can exploit.

Versus Cosan (CSONY): Cosan's holding company structure and 190% debt-to-equity ratio create financial strain, while Ultrapar's 0.99 ratio and direct operational control enable faster decision-making. Cosan's negative 86.43% ROE contrasts sharply with Ultrapar's 18.76% ROE, highlighting Ultrapar's superior execution.

Moat sustainability: Ultracargo's port concessions, Hidrovias' waterway rights, and Ultragaz's terminal infrastructure create regulatory and asset-based barriers that new entrants cannot easily replicate. The digital ecosystem (Abastece Aí, Km de Vantagens) adds a technology layer that enhances customer stickiness, with network effects that improve as more services are bundled.

Risks and Asymmetries: What Could Break the Thesis

Regulatory Reversal: The Carbono Oculto Operation's success depends on sustained political will. If enforcement lapses, irregular players could regain market share, compressing Ipiranga's margins. Leonardo Linden's caution—"we have to be aware that it's not over"—reflects this risk. A change in government policy could undo the single-phase ethanol taxation and tax solidarity gains.

Petrobras Dependence: Ultrapar sources the majority of its fuel and LPG from Petrobras. While current pricing has been stable, any supply disruption or Petrobras' potential re-entry into retail fuel distribution (reportedly under consideration) would pressure Ipiranga's volumes and margins. This is a moderate-high probability risk given Petrobras' 89% LPG market control.

LPG Regulatory Overhaul: The ANP's proposal to end brand respect and allow partial LPG refilling threatens safety standards and could enable illegal refilling operations. Rodrigo Pizzinatto's warning that this "creates space for unlawful players, tax evaders and opportunistic companies" highlights the risk. If implemented, Ultragaz's 17% market share and pricing discipline could erode.

Hidrovias Execution: Integrating a logistics company is complex. Seasonal navigability issues in Q4 could temporarily depress results, and operational missteps could delay synergy realization. However, the sale of cabotage reduces integration scope, and Decio Amaral's operational focus mitigates this risk.

Macroeconomic Slowdown: Brazil's economic growth directly impacts fuel demand and agribusiness exports. A recession could stall Ipiranga's volume recovery and reduce Ultracargo's utilization. However, Ultrapar's defensive LPG business and long-term storage contracts provide downside protection.

Upside Asymmetry: If regulatory enforcement sustains and Hidrovias delivers full synergies, consolidated EBITDA could exceed BRL 7.5 billion in 2026, representing 25% upside to current consensus. The Virtu LNG acquisition and potential BioLPG developments offer additional optionality not reflected in the stock price.

Valuation Context: Cheap for a Reason That No Longer Applies

At $3.94 per share, Ultrapar trades at a market capitalization of $4.22 billion and an enterprise value of $6.89 billion. The valuation metrics reflect a market still pricing the company as a distressed fuel distributor:

• P/E of 7.7x vs. Petrobras at 5.7x, but Petrobras has regulatory interference and pricing constraints that Ultrapar doesn't face
• EV/EBITDA of 6.3x vs. Vibra's implied higher multiple, despite Ultrapar's superior margins and diversification
• Price-to-sales of 0.16x reflects deep undervaluation relative to the asset base and cash generation
• Dividend yield of 8.0% with a 27.8% payout ratio, indicating sustainable high returns to shareholders
• Free cash flow yield of 8.5% (P/FCF of 11.8x) vs. Raízen's negative FCF, highlighting capital efficiency

The market is valuing Ultrapar based on historical fuel sector challenges, not the transformed business model. Hidrovias alone is on track to generate BRL 1.5 billion in annual EBITDA, which at a 6x multiple would be worth BRL 9 billion—more than Ultrapar's current enterprise value. This suggests the market is either undervaluing Hidrovias or assigning zero value to Ipiranga's turnaround and Ultracargo's expansion.

Peer comparison: Vibra trades at higher multiples despite lower margins and no logistics exposure. Raízen's negative margins make it uninvestable for many. Petrobras' state control creates governance risks. Ultrapar offers the best combination of growth, profitability, and capital discipline in the sector.

The catalyst: Q4 2025 results will be the first to show Hidrovias' full consolidation impact and Ipiranga's sustained margin recovery. If the company delivers EBITDA above BRL 2.0 billion and leverage below 1.5x, multiple expansion is likely as the market recognizes the transformation.

Conclusion: A Transformed Company at a Distressed Valuation

Ultrapar has executed a strategic pivot that makes it nearly unrecognizable from the fuel distributor that struggled with illegal competition in 2024. The Hidrovias acquisition creates a new earnings engine tied to Brazil's agricultural export growth, while regulatory enforcement finally levels the playing field for Ipiranga. Ultracargo's terminal expansions and Ultragaz's new energy solutions provide additional layers of defensive, high-margin growth.

The financial evidence is clear: operating cash generation nearly tripled in Q3 2025, leverage is declining despite heavy investment, and management is allocating capital with discipline toward 20% ROIC targets. The competitive moats—port concessions, waterway rights, terminal infrastructure, and digital ecosystems—are stronger than at any point in the company's history.

Yet the stock trades at valuation multiples that imply permanent decline. This disconnect creates an attractive risk/reward profile: downside is protected by the 8% dividend yield, defensive LPG and storage businesses, and strong balance sheet, while upside from sustained regulatory enforcement, Hidrovias integration, and multiple re-rating could drive 50-70% returns over 18-24 months.

The critical variables to monitor are the durability of the Carbono Oculto Operation's impact on fuel market irregularities and Hidrovias' ability to deliver on synergy targets. If both execute as management expects, Ultrapar will have successfully transformed from a cyclical distributor into a structural growth infrastructure play—at which point the market will be forced to re-rate the stock from 6x EBITDA to a multiple that reflects its improved quality and growth prospects.
