3 Total Net Income of R$ 839 million and Recurring¹ of R$ 713 million In the third quarter of 2026, we maintained double-digit growth in total revenue (R$ 11 billion²; +10% vs. 3Q25) and reported a net income of R$ 839 million (+1% vs. 3Q25), with recurring net income¹ of R$ 713 million (-14%), delivering an ROAE of 20.7% (17.6% on a recurring basis¹). Amid a more credit-challenging environment, the complementarity across business verticals and our increasingly diversified portfolio contributed to the resilience of Porto Group, sustaining value creation and the company’s continuous growth. Performance of Verticals, compared to 3Q25: Porto Bank: revenue2 grew 13%, reaching R$ 2.0 billion, driven by growth in Consortium2 (+21%); Financial Risks (+12%) and Credit Cards, Financing and Loans (+11%). Credit losses totaled R$ 843 million (+48%), due to a more adverse credit cycle in the market and a more conservative risk management approach, resulting in higher provision. Initiatives to enhance credit portfolio quality are already starting to reflect in healthier indicators. We remain cautious regarding the macroeconomic landscape. The efficiency ratio improved 3.3 p.p., reaching 27.4%, a result aligned with our efficiency improvement targets and balanced with the necessary investments to sustain the expansion of the digital ecosystem. Net income reached R$ 171 million (-13%). Porto Saúde: revenue grew 12%, reaching R$ 2.5 billion. The growth was driven by an increase of 22% in health insurance members, reaching 956 thousand, and 16% in dental lives, reaching 1.3 million. The loss ratio reached 82.0%, an increase of 4.7 p.p., with approximately two-thirds of this increase stemming from disruptions in the oncology care chain and atypical seasonality between the second and third quarters. while approximately one-third was driven by organic claims growth. Income in the period was R$ 84 million (-34%). Porto Seguro: Revenue and premiums totaled R$ 6.2 billion (+9%), driven by double-digit growth in the Auto segment (+10%), which added 264 thousand vehicles, reaching an insured fleet of 6.5 million automobiles, reinforcing the segment’s acceleration trajectory. Additionally, P&C grew by 9% and Life by 2%. In the composition of the operating and financial front, the amplified combined ratio remained at healthy levels (86%; +1 p.p.). As a result of these dynamics, net income for the period reached R$ 443 million (-2%), while ROAE remained above the 30% level for the sixth consecutive quarter, reaching 32% in 3Q26. Our Message 1Adjusted for: i) the recognition of deferred tax credits ( -R$ 135.4 million), previously provisioned as losses, resulting from the ongoing corp orate reorganization of Porto Serviço; and ii) a cash benefit (+R$ 9.2 million) from an income tax reduction related to the amortization of goodwill from CDF . 2Excluding the effects of the new revenue and cost deferral model for the Consortium, now applied by group and quota. Earnings Release 3Q26 Paulo Kakinoff Porto Group’s CEO

4 Porto Serviço: Porto Serviços recorded R$ 660 million in revenue (+9%), driven by 9% growth in both Strategic Partnerships and Porto Partnerships and 39% growth in Digital Products. The quarterly result was R$ 52 million(34%). We maintained our focus on structuring and expanding strategic partnerships, surpassing 80 partners in total. These initiatives reinforce our goal of further diversifying our business lines and expanding our service offerings. The financial result was R$ 309 million in the quarter (-19%). Revenue from the financial investment portfolio (ex-pension plan and ALM), managed by the Treasury, was R$ 355 million, which accounts for 63% of CDI. The 3Q26 results were mainly impacted by the low IPCA carry ratio during the quarter, reflected in securities marked to the curve, and by the performance of the equity allocation being lower than the IBOV index. The operating efficiency ratio¹, which considers the sum of Administrative Expenses in relation to Total Revenue, was 10.6%, accounting for an improvement of 0.4 p.p. in 3Q26, aligned with our efforts to generate efficiency gains. During the quarter, we were recognized as the second-best company to work for in Brazil by the Great Place to Work (GPTW) ranking, in the Giants category (over 10 thousand employees). This marked our fifth consecutive appearance among the Top 10. We believe that looking after the well-being and growth of our people is what truly sustains the excellence of our deliverables and the company’s continuous development. Another recognition of the ongoing development of our brand was Porto Seguro’s leadership in the segment ranking in the Top of Mind survey, conducted by the newspaper Folha de S. Paulo, for the 13th consecutive year. Our apps have reached the milestone of 6.5 million users (+21%). The digitization process is a strategic movement that aligns Porto's Care essence with the creation of increasingly friendly, fluid, and suitable journeys for the contemporary reality. Among our 19 million customers, we had over 186 million digital interactions and services in 3Q26 (+52%), with end to end resolution of over 73% of requests via WhatsApp (+6 p.p.). Digital service contributes to keeping our NPS at excellence levels. Thus, we remain focused on our North Star: the balance between Essence and Strategy, building an even stronger Porto every day. I close this message with our most sincere appreciation to everyone building this journey alongside us.

The combined ratio reached 90.5% for the quarter (+0.9 p.p. vs. 3Q25). Porto Seguro continued expanding its operations through more segmented offerings, delivering high ratios of profitability and customer satisfaction. Over the past year, we have expanded the portfolio, from entry-level products to the most premium lines. In addition to the launch of automobile and motorcycle products at Azul, the company's entry-level brand, Porto has strengthened its presence in the Premium and Private segments, offering new coverage options for this segment. We have made progress in the cross-selling front, offering car, home, and cell phone insurance in bundled deals. In addition to the growth with individual customers, the company advanced its operations in the segment for businesses, with offerings tailored to the clients' needs, thus progressing in sales and market share in the commercial segment. The company continues to innovate with the expansion of "15 Minutes," a program that guarantees the arrival of automobile assistance within 15 minutes between 10:00 p.m. and 5:00 a.m. for Porto customers. Launched at the end of 2025 in the São Paulo Metropolitan Region, the program was expanded to six new locations this year. Furthermore, we made significant advances in digital through smoother shopping journeys, which increase both client satisfaction and operational efficiency. The NPS was above 80 points in the Auto insurance of the Porto and Azul brands and in the Homeowner insurance of the Porto brand, while the Administrative Expenses (D.A.) ratio stood at 9.8% for the quarter (-0.1 p.p. vs. 3Q25) and 10.0% year-to-date (-0.2 p.p. vs. 9M25), reaching all-time low levels for both periods.

On the analytical fronts, we continue leveraging the company's scale to advance in the disciplines of pricing, subscription, and claims. In addition to constantly improving the models, we maintain discipline in pricing to preserve our margins. In the claims sector, the advanced use of data and technology has been essential to bring increasing fluidity to the journey of clients and brokers.

In both products, we maintained consolidated leadership with gains of 1.5 p.p. and 0.8 p.p. in market share¹, respectively. This progress is enhanced by new initiatives in the Homeowner sector, such as Combined Protection at Azul and the strengthening of the Premium and Private segments, ensuring coverage across different client profiles. Among the other segments, we highlight the 17.7% growth in Portable and Cell Phone insurance, driven by increased cross-selling and digital sales. The total loss ratio of P&C products was 32.2% in 3Q26 (+1.5 p.p. vs. 3Q25), explained by the increase in the frequency of weather events associated with El Niño, nevertheless remaining at levels considered healthy by the Company.

15 The loss ratio of Health Insurance + Dental Insurance was 82.0% (+4.7 p.p. vs 3Q25). The Health Insurance loss ratio was at 83.3% (+5.0 p.p. vs. 3Q25), with approximately two-thirds of this increase stemming from disruptions in the oncology care chain and atypical seasonality between the second and third quarters; while approximately one-third was driven by organic claims growth. The third quarter of 2026 reflected the operational challenges for the period. Despite the slowdown in the quarter, Porto Saúde remains consistent year to date, supported by the profitability of previous quarters, achieving cumulative net income of R$ 443.5 million (+7.8% vs. 9M25).

Although an improvement in credit risk indicators is observed, we still view the future outlook with caution. The Institution maintained business growth by reaching a milestone of 7.3 million transactions (+29.9% YoY), driven by the acceleration of digital fronts and the capture of synergies in the Porto ecosystem. The revenue¹ increased by 12.5% compared to the previous year with Fee-Based growing 21.7% and Net Financial Margin reaching 6.0%. The efficiency ratio of 27.4% in 3Q26 is a key pillar of the structural cost-to-serve reduction strategy. This reduction was based on: 1) focus on contract renegotiation, 2) expansion of self-service in customer support, 3) digital billing; 4) internalization of technology services; and 5) the migration from the digital account model via BaaS to the internal development of a core banking. The loan portfolio reached R$ 23.7 billion, an increase of 9.2% compared to 3Q25. The managed portfolio of the Consortium grew 28.8% compared to the previous year, reaching R$ 132 billion. Although credit deterioration reduced profitability, the operational fundamentals remained solid, highlighted by revenue growth, business expansion, and the continued evolution of operational efficiency. 7.3 M in businesses (Sep/26) +29,9% YoY Main Highlights R$ 2.0 B in revenues (3Q26) +12.5% YoY1 • Net income of 170.7 million (-12.9% YoY and +23.9% QoQ), with ROAE of 20.3% • Efficiency ratio 27.4% (-3.3 p.p.

In Digital Products, revenue grew 38.6% in 3Q26, driven primarily by increased awareness from the release of a web series featuring digital influencer Juzão, and by the launch of Casa em Dia, a multi-service product that allows different residential maintenance needs to be addressed in a single visit. In the Porto Partnership, revenue increased 8.8% year over year (vs. 3Q25).

30 The Financial Result was R$ 309.5 million in 3Q26 (-19.2% vs. 3Q25). Revenue from the financial investment portfolio (ex-pension plan and ALM Porto Cap), managed by the Treasury, was R$ 355.3 million in 3Q26, which accounts for 62.9% of CDI. The 3Q26 results were primarily impacted by two factors: (i) a low IPCA carry ratio during the quarter, reflected in securities marked to the curve, and (ii) the performance of the equity allocation being lower than the IBOV index. The total portfolio of financial investments, which includes resources from pension plan participants, reached R$ 27.3 billion. Excluding resources from social security technical reserves, the total portfolio of financial investments totaled R$ 20.7 billion and reached a return of 2.1% in the quarter (60.3% of CDI). The Company considers the pursuit of capital preservation to be a relevant objective within the strategy for allocating the financial investment portfolio due, for example, to the need to protect operations against inflationary components (e.g.: parts inflation, which has an impact on the cost of motor vehicle insurance indemnities, collective bargaining, among others). And for that, it incorporates other asset classes in its portfolio allocation, which may result in a detachment in relation to the CDI.

(2) The difference between total treasury income (R$ 355.3 M in 3Q26) and the result from financial investments (R$ 253.5 M in 3Q26) is explained by adjustments to allocations between lines of income from financial services which are current ly reallocated mainly to Porto Bank and to funds not managed by the treasury area.

The realization of these expectations will depend on several factors, many of them external to the Company, and actual results may differ from the projections presented. The projections will be monitored and reviewed by the Company, pursuant to the applicable regulations. 2Porto Bank Total Revenue: Revenue impacted by improvements in the deferral method of consortium revenues and costs and now net of expenses with Rewards and card brands. 3New Porto Bank Efficiency Ratio: New calculation of Porto Bank Efficiency Ratio: (Operating and Administrative Expenses net of Rewards and brands) / (Net revenue net of taxes, Rewards and brands – Commission). Expenses such as Rewards and flags will no longer be part of operating expenses and will become revenue deductions in 2026. 4Effective Rate: Revision of the Effective Rate resulting from the reversal of deferred taxes on the surplus from the acquisition of a subsidiary after its merger. Projections for the year 2026 on the evolution of indicators considered relevant by the Company: The company's capital expenditures (Capex) reflect our strategic commitment to the technological modernization of the entire ecosystem, highlighting: The internalization of Core Banking and the development of Porto Bank's Corporate Account (Conta PJ), key milestones in the financial operation's transformation that combine the migration from the Bank as a Service (BaaS) model to a proprietary core banking platform with the expansion of the offering for corporate clients; and the Novo COL – Corretor Online Project, which transforms the brokers' sales and post-sales journey through a 100% digital, integrated, and high-performance channel. To sustain these innovations and ensure efficiency, the technology foundation receives structural investments through the Digital Resilience program, aimed at ensuring business continuity, enhancing excellence in product engineering, and actively mitigating architectural technical debt, in addition to the Auto R3 project, which unifies the systems and back office of Porto Seguro and Azul Seguros. This integration eliminates redundancies and creates a unified platform for brokers to manage both brands, maintaining Azul's cost -benefit proposition supported by Porto's infrastructure.

By integrating these references and structured processes into the creation of tools focused on supply chain development, such as our exclusive training programs in Human Rights and Waste Management, we can not only optimize processes but also strengthen a network of suppliers, workshops, and service providers that are far more aware, innovative, and aligned with a sustainable corporate future. The strategic success of this collaborative engagement with our partners is already reflected in the participation of more than 280 respondents in our maturity survey and the exceptionally high satisfaction level across our network, which recorded an average NPS of 98 across the six events held, with more than 1,000 total attendees and 580 unique Brazilian corporate tax IDs (CNPJs). Insurance inclusion Our team sponsored and actively participated in the “Insurance for Every Budget” fair in Paraisópolis—an initiative by CNseg and G10 Favelas. Driven by the belief that insurance inclusion is essential to bringing care and peace of mind to everyone, and mindful of the fact that most residents of outlying communities are interested in protection products, we reaffirmed our commitment to breaking down barriers and democratizing access to insurance. After all, developing services that respect local realities and caring for our ecosystem is our truest way of being a Porto Seguro for people and their dreams. 603.2 452.0 458.5 527.4 640.3 3Q26 4Q26 1Q26 2Q26 3Q26 Revenue and Premium from Sustainable Products and Businesses (R$ million) ESG

42 For millions of Brazilians, a car represents much more than a means of transportation. It is part of the accomplishments, family trips, freedom, and stories built over the course of a lifetime. As part of this movement, and with the goal of continually bringing more care and experiences to our customers and partners, we renewed our sponsorship of Rally do Sertões, the largest off-road competition in the Americas. As the official sponsor of the Rally do Sertões, Porto Seguro had exclusivity in the insurance segment, with its brand present throughout the competition, including at the start and finish areas, on backdrops, and in the event’s official content. Additionally, Azul Seguros launched an educational campaign focused on traffic education, prevention, and safety, with awareness initiatives aimed at motorcyclists and drivers. The campaign debuted on National Traffic Day, and used the Blue Lane—an initiative created by the São Paulo Municipal Government—as a starting point to raise awareness about safe coexistence between motorcyclists and drivers. In partnership with CET, the Traffic Engineering Company, the campaign features content aimed at motorcyclists and drivers, providing information and guidance about the Blue Lane and sharing the road safely. The initiative also included a 30-second commercial that aired on broadcast TV in São Paulo, along with OOH advertising on clocks located along the city’s main roads. In August, tickets went on sale to the general public for the Porto Bank Grandstandat the Formula 1 MSC Cruises São Paulo Grand Prix 2026and sold out in just four minutes. Porto Bank Card customers had access to exclusive benefits, such as 15% off ticket purchases and the option to pay in up to six interest-free installments. The initiative reinforces the bank’s commitment to providing customers with access to special experiences, combining convenience, financial benefits, and the excitement of following one of the world’s premier motorsport events up close. The Porto Serviços vertical also held CAP Experience, an event in São Paulo that brought together managers and partners from the Porto Serviços Automotive Center network from across Brazil for a meeting focused on strengthening network integration and advancing initiatives such as customer service, technology, management, business, and service quality. During the period, the vertical also held a special event focused on financial education and planning for service providers and their families. In the third quarter of 2026, we reinforced our relationship and proximity strategy with clients and brokers, expanding the brand strength of our ecosystem of products and services in activation territories: With initiatives designed to promote well-being and physical activity, Porto is the new sponsor, bringing its commitment to care to Ibirapuera Park. Lasting five years, the partnership—which brings together initiatives from Porto’s different business lines—expands the company’s presence in areas related to well-being and quality of life, providing solutions and benefits for the various stages of visitors’ experiences at the park. The initiative brings together different areas of the company to provide comprehensive care to the public: Porto Saúde began sponsoring the park’s 4 km bike lane, while Porto Seguro provides free phone-charging kiosks. To support cyclists and visitors, Porto Serviços provides self-service bike stations and service providers on standby on weekends for minor repairs. Completing the experience, Porto Bank customers received special conditions at restaurants in the park and surrounding area, such as Bottega Bernacca, Selvagem, and Vista, when they use their Porto Bank card. Additionally, in São Paulo, Ibirapuera Park itself hosted the first Porto Saúde Blue Run Night Edition. The event marked the circuit’s evolution by introducing a new nighttime experience that combined sports and entertainment with a carefully planned operation designed to preserve the park’s flow. And this encouragement of preventive health goes beyond our day-to-day care, gaining even more momentum in the streets with the 2026 season of Blue Run, which has reached more than 15,000 people so far. In the third quarter alone, we promoted street races in Rio de Janeiro, São Paulo, and Salvador. The circuit continues traveling throughout Brazil to materialize our strategy of connecting the brand to the public through sports.

43 Strengthening Porto Group After more than 265,000 spectators and 350 performances, Rita Lee, A Musical Autobiography has opened new ticket sales for the final stretch of its 2026 run at Porto Theaterin São Paulo. Starring Mel Lisboa, the musical has released its final batch of tickets for performances in the capital from October 30 to December 13. In August, Porto hosted an exclusive experience for the top-performing brokers in the Fecha com a Porto campaign, taking approximately 300 winning professionals to enjoy the Barretos Rodeo Festival, one of the country’s premier events. Entertainment After a decade of partnership with brokers, PromoDigital evolved into the Content Factory, providing marketing support to help brokers accelerate sales with Generative AI and access to more than 300 ready-to-use videos for social media. From an unprecedented partnership with Domingão com Huck, featuring commercials on Sundays, Porto Bank began investing on a national scale to transform the consortium into an increasingly present alternative in the daily lives of Brazilians, with a leading role in financial education, brand strengthening, and expansion into new regions. Between August and September, the vertical also launched its Acelera Consórcio campaign, allowing brokers to take advantage of special terms when selling the product. The initiative brought together commercial incentives, training activities, exclusive experiences, and special terms for customers, reinforcing the company’s commitment to strengthening its distribution channel and expanding the consortium business in the market. Education With great satisfaction, Porto announced its partnership with Eldorado Radio and embraced the station’s return, now on the 107.9 MHz frequency, to bring back the quality information, culture, and connection that the city loves so much. Eldorado’s relationship with São Paulo and its listeners has much in common with the way Porto views society: With care and attention, always seeking to strengthen initiatives that help build our culture and identity. Porto took part in the National Brokers Congressin Rio de Janeiro, participating in panels and business sessions featuring content on innovation strategy, the impact of AI, and how brokers can benefit from data to turn market changes into more opportunities to drive sales, including for the same client. Seeking to expand its digital presence and democratize access to homeowner and automotive services, the vertical also released two web series, joining forces with content creators Juliana Muncinelli (Juzão) and Eduardo Bernasconi. The initiative brought together information, entertainment, and digital content to make Porto Serviços' solutions better known and more connected to people's everyday lives.
