São Paulo, November 11, 2022 - COSAN S.A. (B3: CSAN3; NYSE: CSAN) announces today its results for the third quarter (July, August and September) of 2022 (3Q22). The results are presented on a consolidated basis, in conformity with the accounting practices adopted in Brazil and International Financial Reporting Standards (IFRS). The comparisons made in this report consider 3Q22 vs. 3Q21, except where otherwise indicated. On February 28, 2023, as per note 3.2 of the Interim Financial Statements as of September 30, 2022, Cosan S.A. made a voluntary restatement to correct an accounting recognition error of financial asset related to acquired Vale shares.

Note 2: Adjusted EBITDA and Net Income exclude non-recurring effects, as detailed on page 12 of this report. Note 3: As from 1Q22, the results of Cosan Investimentos comprise Radar, Payly, Trizy and Porto São Luis, as well as other investments and expenses. Note 4: EBITDA of Cosan Corporate before equity income (loss). Figures for 3Q21 included the results of Payly, Trizy and other expenses of Cosan Investimentos. Note 5: Free Cash Flow to Equity (FCFE) before dividend payments. Note 6: Net Debt/EBITDA in the last 12 months (LTM) adjusted by lease liabilities (IFRS 16). Cosan's adjusted EBITDA in 3Q22 came to R$4.1 billion, 19% higher than in 3Q21, thanks to the record result of Rumo, reflecting the growth in transported volumes and higher average tariff, and the consolidation of Commit by Compass and PetroChoice by Moove. Adjusted net income came to R$453 million (-14.8%) in 3Q22, affected by non-recurring items in the comparison period, as well as the lower Raízen's results, which were partially offset by the results of the other businesses of the group and the mark-to-market of Vale's shares. Free cash flow to equity (FCFE) was R$6.9 billion in the quarter, mainly due to the bridge loan of R$8 billion taken out by Cosan for acquiring shares in Vale. The result represented a 17% decrease in FCFE of 3Q21 (R$8.3 billion), reflecting incorporation of the proceeds from Raízen's Initial Public Offering (IPO) and the injection of the private capital raised by Compass in the period. The leverage ratio ended the quarter at 3.1x, up 1.0x, due to the increase in Raízen net debt affected by consumption of operating cash related to the composition of inventory at the beginning of the harvest. Compared to 2Q22, the 0.6x increase reflects the non-recurring effects at Cosan Corporativo, from Raízen's IPO and the acquisition of Biosev in 3Q21, partially offset by the result expansion of other businesses in the portfolio.

A. Message from the CEO We are approaching the end of another year! The whole world has undergone – and is still experiencing – profound changes. This year was as complex or even more than during the years when the pandemic was peaking. Global geopolitical transition, supply chain disorganization, shortage of basic products, rising energy prices and the effects of climate change have brought challenging scenarios for both countries and companies. Despite this moment of volatility, I am very optimistic about Brazil's future. Our country has a great competitive and comparative advantage in five strategic areas in the world economy: food production; clean energy generation; production of gas and oil, generation of carbon credits and mining. At Cosan, we invest in a unique portfolio of companies focused on those sectors where Brazil has unrivaled strength. Thus, we want to continue growing in a sustainable and meaningful way for society, creating value for all our stakeholders. And always remembering that being sustainable is key for the perpetuity not only of business, but of our planet. In this third quarter of 2022, we continued our intense journey full of challenges in each of our businesses. At Raízen, our joint-venture with Shell, we continue taking to the market the best decarbonization alternatives based on sugarcane, exporting sugar, ethanol and now our second-generation ethanol (E2G) worldwide. We recently signed a long-term contract with Shell to trade second-generation cellulosic ethanol, which represents an important milestone in the E2G project. Rumo has invested billions of reais in developing the logistics that contributed to making the Brazilian agribusiness increasingly competitive, also reducing emissions by replacing trucks with world class trains. As a result, the company delivered record EBITDA and volumes transported in the quarter, demonstrating its operational capacity to meet the demand with quality and efficiency. In addition, we announced, after the end of the quarter, the first phase of the Extension Project in Mato Grosso until Lucas do Rio Verde kick-off. At Compass, key part in the energy transition process, we concluded another quarter of consistent results, reflecting the performance of Commit, the excellent operational performance of Sulgás and operating efficiency gains at Comgás, reducing the effect of the already expected contraction in industrial volumes. In addition, we remained dedicated to integrating Commit, allocating key professionals to the team and focusing on replicating our business model, while working to conclude the divestments announced. Moove remained focused on consolidating PetroChoice, which will further strengthen our position as a relevant global player and our growth strategy supported by robust a portfolio and unique positioning in the Americas and Europe. At Cosan Investimentos, we increased our interest in Tellus and Janus, companies that manage agricultural properties, as well as Radar, which together manage 330,000 hectares. The portfolio also could create new opportunities for creating value by generating carbon credits for protecting preservation areas. Soon after the quarter end, we announced the acquisition of a non-controlling interest in Vale, which is an investment aligned with our strategy of portfolio diversification and capital allocation. Vale is a unique and irreplicable asset focusing on key natural resources for energy transition and decarbonization. We are confident that we can contribute to the creation of value alongside the shareholders and executive team. None of this would be possible if it weren't for our people. In a Group like ours, we must always develop our employees to be the best at what they do. Our value creation is greatly based on the Human Capital we have built, which is marked by a strong culture of aligning strategic thinking and discipline with ESG values in all areas and sectors where we operate. Diversity is also part of the Cosan Culture, which can be proven through our financial performance; however, we still have a lot to improve in this area. With the best professionals, we will continue to grow and walk hand in hand with sustainability. Looking at all these achievements, I am very proud that we were named Company of the Year by Exame, one of Brazil's main business magazines, which shows that we are on the right path on this journey that has been, and always will be, intense and full of challenges. Congratulations to the Cosan team for these achievements. Let's move forward on this journey together! Best regards, Luis Henrique Guimarães Cosan CEO

For comparison purposes, includes Biosev's pro forma results, prior to its merger in August 2021, in Renewables and Sugar. In 3Q22, period that marks the end of the first half of the crop year, Raízen reported adjusted EBITDA of R$2.8 billion (-14%), mainly affected by the adverse effects on fuel inventories in Brasil, that reflected the widespread decline in the prices of products. Renewables: Adjusted EBITDA was R$1 billion (-41%) in the quarter, reflecting inflationary pressures on costs and expenses and the lower own sales volume, which were partially offset by revenue growth (+9%) and higher bioenergy sales. Sugar: Adjusted EBITDA reached R$1.2 billion in 3Q22, more than doubled the adjusted EBITDA of 3Q21, driven by higher share of direct sales and greater prices. These effects were partially offset by the already expected increase in costs. Marketing & Services: In 3Q22, the adjusted EBITDA of the integrated platform Brazil and LatAm (Argentina and Paraguay) came to R$731 million (-27%). The Brazil operation was mainly affected by fuel market dynamics, with successive and atypical price declines affecting inventories, and by carbon credit prices. The result of LatAm operation was in line with the same period of previous year, reflecting the greater sales volume and operating efficiency gains, which were partially offset by the higher pressure from inflation and exchange rates.

B.2 Rumo Indicators 3Q22 3Q21 Chg.% (jul-sep) (jul-sep) 3Q22/3Q21 Total transported volume (millions RTK) 20,260 16,367 23.8% North operation 15,634 11,802 32.5% South operation 3,641 3,665 -0.7% Container 984 899 9.5% Adjusted EBITDA1 (BRL mln) 1,429.2 903.2 58.2% Note 1: EBITDA adjusted by non-recurring effects, as detailed on page 12 of this report, where applicable. Rumo achieved record EBITDA of R$1.4 billion (+58%) in the quarter, leveraged by the record transported volume of 20.3 billion RTK. The growth was due a bigger corn harvest, a steady export seasonality, the ramp-up of the Central Network and better operational performance, which allowed capacity gains. The highlight this quarter was the greater transported volume in the agricultural products segment in the North Operation (+33%) and the continuous improvement in operating indicators, with a dwell time reduction of 13.4% at the Port of Santos/SP and a 5.3% fuel consumption decrease per RTK. Despite the higher volume, the port's market share contracted 3.5 p.p. compared to 3Q21, when logistics demand was lower during the corn crop setback in 2021, demanding a more competitive strategy from Rumo. EBITDA margin was 48% in 3Q22, up 2.4 p.p. from 3Q21, driven by the 23% increase in tariffs and higher transported volumes.

Note 2: EBITDA adjusted by non-recurring effects, as detailed on page 12 of this report, where applicable. In 3Q22, adjusted EBITDA came to R$966 million (+11%), reflecting mainly the consolidation of Commit's results, due to conclusion of the acquisition of 51% interest in former Gaspetro, which had a positive impact on volumes and EBITDA as from 3Q22. These effects were offset by the lower sales volume in the industrial segment, reflecting the scheduled maintenance shutdowns, and cogeneration in Comgás, despite the recovery of the commercial segment and the resilience observed in the residential segment. B.4 Moove Indicators 3Q22 3Q21 Chg.% 2Q22 Chg.% (jul-sep) (jul-sep) 3Q22/3Q21 (apr-jun) 3Q22/2Q22 Total Volume1 ('000 cbm) 158.2 95.2 66.2% 128.8 22.8% EBITDA (BRL mln) 245.4 156.6 56.7% 232.1 5.7% Note 1: Includes the sales volume of lubricants and base oils. Moove's EBITDA was R$245 million (+57%) this quarter, thanks to the higher profitability of its portfolio combined with sales expansion. In addition, 3Q22 was the first complete quarter in which Moove were impacted by the consolidation of the PetroChoice and Tirreno results. We remain focused on capturing operating efficiency gains in line with our supply and pricing strategy.

The 54% decline in relation to 2Q22 was due to the mark-to-market adjustment of the price appreciation in the agricultural properties of Radar's land portfolio in 2Q22.

Note 2: Expenses adjusted by non-recurring effects, as detailed on page 12 of this document, where applicable. The general and administrative expenses of Cosan Corporate amounted to R$70 million in 3Q22, down 30% from 3Q21, which was affected by the changes in long-term compensation plans in the quarter. Other adjusted operating expenses ended 3Q22 at R$27 million, in line with the comparison period. C.

Income from financial investments increased, reflecting the higher average cash balance and higher interest rate in the comparison period. Interest on Net Debt totaled R$342 million for the quarter due to the effects listed above, partially offset by the mark-to-market of Vale's shares. The weighted average cost of debt of Cosan Corporate in 3Q22 was CDI + 1.88%. Expenses with other charges and inflation adjustments amounted to R$138 million in 3Q22, as a result of the mark-to-market adjustment of the Total Return Swap, reflecting the drop in the price of Cosan's shares, partially offset by the higher price of Rumo's shares. Banking expenses, fees and other totaled R$121 million, an increase resulting from brokerage expenses with the issuance <br>![Graphics](img93709db255064dd2b042.jpg)<br>

In addition, although Cosan owns 100% of Cosan Investimentos, its direct interests in Radar, Trizy and Payly are, respectively, 50%, 57% and 75%. Note 2: Net income excluding equity income (loss). Until 4Q21, it included Payly, Trizy and other expenses of Cosan Investimentos. Cosan ended the quarter with loss of R$14.9 million, affected by the drop in Raízen's results, reflecting the inflationary pressure on Renewables segment and the fuel market dynamics, partially offset by the results of the group's other businesses and the fair value adjustment of Vale's shares, as explained previously. Compared to 3Q21, the reduction is due to the non-recurring effects of the net gains from Raízen IPO and Biosev merger in the comparison period. These effects were partially offset by the higher EBITDA in most companies of the portfolio and the positive effect from the mark-to-market adjustment of Rumo's shares.

Cosan's consolidated pro forma investments ended the quarter at R$2.1 billion (+31%), mainly due to the higher expenditures at Raízen (+99%) in sugarcane fields, in line with its journey of agricultural productivity gains, acceleration of the construction of the E2G and Biogas plant, and investments in expansion and maintenance of assets and Marketing & Services distribution network. At Compass, the 36% increase is in line with its plan for the year, focusing its investments in operations of natural gas distribution and construction of the São Paulo Regasification Terminal (TRSP), which is on schedule and within budget. On the other hand, the 22% reduction in Rumo's CAPEX, neutralizing the aforementioned effects, corroborating its commitment to capital discipline, with its focus on investments in asset maintenance and projects to expand operating capacity and efficiency gains.

Cosan's consolidated pro forma gross debt ended 3Q22 at R$67.7 billion (+17% versus 2Q22), explained mainly by the bridge loan of R$8 million for the acquisition of Vale's shares at the Parent Company. Raízen also carried out a new issue Certificate of Agribusiness Receivables (CRA), and Cosan prepaid its 2023 Bonds. The transfer of R$4 billion between the Parent Company and Corporate pertains to the transfer of Bond 2029 from Cosan S.A. to Cosan Luxembourg S.A. Due to these changes and the recognition of Vale's shares under marketable securities, at Corporate, net debt balance ended the quarter at R$39.8 billion, 4% higher than in the previous quarter.

The proforma leverage ratio (net debt/EBITDA LTM) was 3.1x in 3Q22 vs. 2.1x in 3Q21. The variation is due to the increase in the proforma net debt, a consequence of higher gross debt at Raízen resulting from consumption of operating cash for the formation of inventories at the beginning of the harvest. Compared to 2Q22, the increase is due to the lower accumulated EBITDA, affected by exclusion of the non-recurring effects registered at Cosan Corporate of approximately R$3 billion, related to Raízen IPO and the acquisition of Biosev in 3Q21. Note that the increase in gross debt in the quarter, due to the R$8 billion loan for acquiring Vale's shares, was offset by recognition of the amount as marketable securities, without any effect on net debt.

E. Relevant matters and Events after the reporting period Relevant matters announced by the Company and its subsidiaries as of the publication date of this document follow. Acquisition of additional interest in Tellus and Janus In line with Cosan's capital allocation strategy, in September, the Company announced the acquisition of an additional 13% interest in Tellus and Janus for the net price of approximately R$1.007 billion, in five annual installments adjusted by the SELIC rate, to hold 20% stake. Tellus and Janus are companies that manage a land portfolio and invest in assets with high production potential in Brazil. The acquisition was concluded in October, with the payment of approximately R$202.9 million corresponding to the first installment. Pursuant to the Shareholders' Agreement, Cosan has decision-making power over the activities of these companies and, therefore, according to the Company's assessment, it has control. Minority stake in Vale In October, Cosan announced the acquisition of a 4.9% stake in Vale, one of the world's leading mining companies, with 2% of this stake acquired by September 30, 2022. In addition, a second transaction was structured, corresponding to an additional financial exposure of 1.6%, which, if approved by Brazil's antitrust authority CADE, could be converted into direct interest in Vale. This transaction is fully aligned with the Company's strategy of capital allocation and portfolio diversification by investing in irreplicable assets in sectors in which Brazil has clear competitive advantages. Long-term aviation fuel supply agreement In September, Raízen signed an agreement to supply petroleum products for aviation with Azul Linhas Aéreas Brasileiras S.A. ("Azul"). Apart from becoming the main aviation fuel distributor for Azul, the partnership will roll out strategic initiatives involving Shell Box and Azul's loyalty program, besides supplying electricity generated by Raízen through distributed generation and opportune sales of sustainable aviation fuel (SAF). Raízen enters on Ibovespa Index In early September, the preferred shares of Raízen (RAIZ4) became a component of the Ibovespa Index ("IBOV"), the main index of B3 – Brasil, Bolsa, Balcão, which combines companies with the highest tradability and representativeness in the Brazilian stock market. The new portfolio is valid from September to December 2022. Becoming a component of this portfolio is an important recognition for Raízen, since it should increase visibility and trading volume in its shares. Acquisition of Payly by Raízen In October, the acquisition of Payly by Raízen was announced, creating a financial services unit in the company that is now the controlling shareholder of Payly. Initially, the unit will offer financial service solutions linked to Shell Box, thereby increasing payment options and credit products for Marketing and Services. In this transaction, Raízen will pay R$78 million to Cosan referring to the acquisition of a 100% interest in Payly. Note that the transaction still will be submitted for approval of Brazil's antitrust authority CADE and requires compliance of the contractual conditions precedent. Accordingly, Payly's assets and liabilities were reclassified as held for sale. New related-party transaction between subsidiaries Comgás and Rumo In October, Comgás entered into a purchase and sale agreement of ICMS credits with Rumo Malha Paulista. The agreement aims to transfer ICMS credits in compliance with the legislation, at a total estimated amount of R$130 million.
