Cosan Q1 EBITDA +60% to R$3.34B ($661M); Loss Narrows

Cosan S.A. (B3: CSAN3 / NYSE: CSAN), Rubens Ometto’s Brazilian infrastructure-and-energy holding and one of Latin America’s largest industrial conglomerates, reported Q1 2026 net loss of R$1.58 billion ($313 million) — narrowing 11 percent from the R$1.79 billion ($355 million) loss recorded in Q1 2025, according to the earnings release published Thursday May 14 after market close.

The Cosan Q1 earnings show a classic holding-company divergence between consolidated operational improvement and balance-sheet-driven bottom-line pressure. Adjusted EBITDA jumped 60 percent year-on-year to R$3.34 billion ($661 million) as portfolio subsidiaries Rumo, Compass and Moove all delivered operational growth. However, consolidated net revenue fell 7 percent to R$9.03 billion ($1.79 billion), reflecting the deconsolidation effect of Raízen — whose carrying value was already written to zero in Q4 2025.

The R$1 billion ($198 million) non-recurring hit dominated the bottom-line variance. Cosan pre-liquidated bonds with 2029, 2030 and 2031 maturities, taking charges through both the net financial expense line and deferred-tax line. Management framed the cost as a deliberate liability-management decision — accelerating the post-capitalisation balance-sheet repair that began with the November 2025 R$10 billion ($1.98 billion) BTG Pactual + Perfin capital injection.

The net financial result was negative R$1.09 billion ($216 million), worsening 51 percent year-on-year. Net debt at holding level closed at R$11.5 billion ($2.28 billion), up 18 percent quarter-over-quarter on absence of dividend inflows and extraordinary debt-management disbursements — but down 34 percent year-on-year benefiting from the late-2025 capitalisation. Cash on hand closed at R$7.7 billion ($1.52 billion).

Key Points

What Cosan Reported in Q1 2026

Cosan S.A., listed on B3 as CSAN3 and on NYSE as CSAN, is the Brazilian infrastructure-and-energy holding company controlled by Rubens Ometto, one of Brazil’s most prominent industrialists. The conglomerate operates five core verticals: Raízen (sugar, ethanol, energy and fuel distribution — joint venture with Shell), Compass (natural gas distribution including Comgás), Rumo (Brazil’s largest rail logistics operator), Moove (lubricants), and Radar (agricultural land management). Cosan also holds approximately a 4 percent stake in Vale.

CEO Marcelo Martins leads Cosan, with founder and chairman Rubens Ometto continuing to drive strategic direction. The company has been undergoing the most significant structural restructuring in its history through 2025-2026, including the November 2025 capital injection of R$10 billion ($1.98 billion) from BTG Pactual and Perfin, the Compass IPO completed in Q1 2026, and the extrajudicial restructuring filing at Raízen.

Q1 2026 net loss reached R$1.58 billion ($313 million), narrowing 11 percent from the R$1.79 billion ($355 million) loss in Q1 2025. The bottom-line improvement comes despite consolidated revenue compression — a function of operational EBITDA expansion across all five subsidiaries combined with R$1 billion ($198 million) of non-recurring charges from the bond pre-liquidations.

Consolidated net revenue reached R$9.03 billion ($1.79 billion), down 7 percent year-on-year from R$9.7 billion ($1.92 billion) in Q1 2025. The revenue decline reflects the deconsolidation effect of Raízen following the Q4 2025 write-down of the carrying value to zero. Management presents the consolidated figures excluding Raízen — meaning Q1 2026 numbers reflect the four remaining operational subsidiaries plus the Vale stake.

Adjusted consolidated EBITDA jumped 60 percent year-on-year to R$3.34 billion ($661 million). This is the headline operational data point — every consolidated subsidiary delivered EBITDA growth in Q1, demonstrating the underlying portfolio quality even as the Raízen pressure dominated the headlines. Sequentially however EBITDA fell from R$3.8 billion ($752 million) in Q4 2025, reflecting seasonal dynamics in some subsidiary operations.

Rumo delivered the strongest subsidiary performance. Adjusted EBITDA at the rail logistics operator reached R$1.74 billion ($345 million), up 7 percent year-on-year. Volume transported jumped 25 percent — driven especially by the North operation, which benefited from grain-flow expansion and fixed-cost dilution. As the Rio Times reported separately, Rumo Q1 net income jumped 41.1 percent to R$266 million ($53 million).

Compass also delivered operational growth. EBITDA reached R$1.33 billion ($263 million), up 2 percent year-on-year — but adjusting for LNG-cargo timing effects, the underlying growth would have been 12 percent. Drivers included higher natural-gas distribution volumes, improved product mix, and expansion of the Edge operations. The Compass IPO completed during Q1 generated R$2.1 billion ($416 million) net proceeds to Cosan parent — a material liquidity event for holding-level balance-sheet repair.

Moove EBITDA reached R$236 million ($46.7 million), essentially flat year-on-year despite a 10 percent increase in lubricant volume sold. EBITDA margin compressed to 9.6 percent — reflecting raw-material cost pressures and mix dynamics. Moove highlighted market-share gains in Brazil and reduced leverage to 1.3x — a meaningful improvement in standalone capital structure for the lubricants business.

Radar was the only subsidiary EBITDA decliner. The agricultural land manager’s EBITDA fell 27 percent year-on-year to R$103 million ($20.4 million), pressured by declines in total recoverable sugar (TRS) prices and soybean prices, plus the absence of asset-sale gains that had bolstered the Q1 2025 baseline. Radar’s smaller absolute EBITDA contribution limits the consolidated impact, but the agribusiness cycle pressure is meaningful sectoral context.

The net financial result was negative R$1.09 billion ($216 million), worsening 51 percent versus the same period in 2025. Cosan attributed the deterioration to costs associated with the bond and debenture pre-liquidations: premium payments, accelerated interest recognition, mark-to-market of hedge positions, and FX variation. These costs are by definition non-recurring within the post-restructuring framework.

Net debt at the holding level (excluding subsidiary debt) closed Q1 at R$11.5 billion ($2.28 billion). Sequentially this represents an 18 percent increase from Q4 2025’s R$9.76 billion ($1.93 billion) — driven by the absence of meaningful dividend inflows during the quarter combined with the extraordinary debt-management cash disbursements. Year-on-year however, the comparison versus Q1 2025’s higher base shows a 34 percent reduction, validating the late-2025 capitalisation impact.

Cash on hand at quarter-end was R$7.7 billion ($1.52 billion) — substantial headroom for the next phase of balance-sheet management. Management highlighted that meaningful disbursements during Q1 went to principal amortisation and financial-expense payments rather than to growth capex — reflecting the strategic pivot from expansion to deleveraging.

The Compass IPO completion was the single most important Q1 corporate event. The transaction generated approximately R$2.1 billion ($416 million) in net proceeds to Cosan — partial liquidity from the natural-gas distribution platform. Cosan retains controlling interest in Compass, but the partial monetisation creates ongoing optionality for further stake reductions if balance-sheet pressure requires.

The Raízen extrajudicial restructuring filing during Q1 was the other defining event. As the Rio Times reported in detail, Raízen filed Brazil’s largest-ever extrajudicial restructuring covering R$55.3 billion ($10.95 billion) in net debt. Cosan’s Raízen carrying value had already been written to zero at Q4 2025 — meaning the Q1 print does not absorb further direct impairment from this development, but the equity-pick-up loss continues.

Why Cosan Q1 Matters

Cosan’s Q1 2026 print is one of the most consequential Brazilian corporate-holding earnings releases of the year — testing whether Rubens Ometto’s R$10 billion ($1.98 billion) emergency capitalisation, Compass IPO partial monetisation, and bond pre-liquidation strategy add up to a credible balance-sheet repair plan, or whether the Raízen-induced cash-flow collapse continues to dominate the group’s trajectory.

The holding-company structural dynamic is unusually transparent in this print. Cosan, like all listed Brazilian holdings, depends on dividends from its operating subsidiaries to service its own corporate-level debt. The R$1.09 billion ($216 million) quarterly financial expense is structurally elevated against the absent dividend inflow from Raízen — historically Cosan’s largest dividend source at approximately R$1 billion ($198 million) annually. Raízen has paid zero dividends to Cosan in 2024 and 2025.

The Raízen context shapes the entire investment thesis. As the Rio Times reported in March 2026, Cosan and Shell’s rescue talks for Raízen collapsed when Cosan ultimately decided not to proceed with the R$1 billion ($198 million) BTG Pactual was prepared to invest through a new partnership. Shell remained the only committed backer with R$3.5 billion ($693 million), versus the R$500 million ($99 million) Ometto pledged through his personal holding Aguassanta.

The Raízen creditor escalation creates additional governance risk. As the Rio Times reported in April 2026, Raízen creditors have submitted a proposal demanding approximately R$8 billion ($1.58 billion) in fresh capital — more than double the R$4 billion ($792 million) Shell and Ometto previously committed — plus the removal of Ometto as Raízen chairman as a condition of the deal. This is no longer a financial restructuring; it has escalated to a corporate governance battle.

The Compass IPO is the structural positive. Compass — which includes Brazil’s largest natural-gas distribution operator Comgás — became publicly tradeable in Q1 2026, generating the R$2.1 billion ($416 million) net proceeds to Cosan. The IPO creates a separate listed valuation vehicle for the gas-distribution franchise and gives Cosan optionality to further reduce its stake if balance-sheet pressure intensifies. Compass’s R$1.33 billion ($263 million) Q1 EBITDA places it among the top Brazilian utility profits.

The Rumo performance validates the rail-logistics thesis. Volume +25 percent year-on-year, particularly the North operation grain-flow expansion, confirms Brazil’s structural agricultural-export advantage. Rumo’s R$1.74 billion ($345 million) EBITDA represents approximately 52 percent of consolidated EBITDA — making Rumo the single most important Cosan asset for current cash generation. The strategic question is whether Cosan would consider further Rumo stake reductions as additional liquidity events.

Moove’s stability against a 10 percent volume increase is the operational concern. EBITDA margin compression to 9.6 percent against rising volumes suggests pricing pressure or input-cost dynamics that are absorbing operational gains. Management’s prior consideration of a Moove IPO — discussed publicly during the 2024 strategic-shift framework — remains a potential future liquidity vehicle if the lubricants business stabilises operationally.

Radar’s 27 percent EBITDA decline highlights the broader Brazilian agribusiness cycle pressure. The TRS price decline and soybean price compression directly transmit into Radar’s agricultural land management economics. This pressure is consistent with the cluster picture across other Brazilian agri-exposed names — 3tentos’s hedge-accounting divergence, SLC Agrícola’s timing-lag from Iran-Hormuz pricing, and the broader commodity-cycle dynamics affecting the sector.

The bond pre-liquidation is a strategic positive disguised as a Q1 cost. Cosan accelerated retirement of R$1 billion ($198 million) of 2029-2031 bonds — incurring premium and accelerated-interest charges now to remove future-period interest-expense burden. This is classic post-restructuring liability-management behaviour, executed at scale that signals management’s confidence in the post-capitalisation balance sheet.

The annual financial-cost burden is the structural challenge. As market analysts have noted, the consolidated group annual financial costs approach R$16 billion ($3.17 billion) — a figure capable of “consuming practically all the cash generation from controlled companies.” Cosan’s balance-sheet repair requires both rate normalisation (Brazil’s 15 percent Selic compression toward 12-13 percent through 2026) and operational subsidiary cash-flow expansion.

For foreign investors, Cosan offers unique structural exposure to Brazilian infrastructure consolidation through both the B3 (CSAN3) and NYSE (CSAN) listings. The Q1 print at -11 percent NI improvement with +60 percent EBITDA growth suggests operational momentum is rebuilding even as balance-sheet challenges persist. Ágora Investimentos’ R$11 ($2.18) DDM-based price target against current ~R$5.66 ($1.12) trading reflects the deep value embedded in the operating portfolio if balance-sheet repair completes successfully.

The 2026 inflection question is binary. Either subsidiary cash flows expand enough — particularly through Rumo’s grain-volume expansion and Compass’s gas-distribution scale — to service the corporate debt structure and allow capital return to shareholders, or further capital actions (additional Compass stake reductions, Rumo stake monetisation, Vale stake sale, or another capital injection) become necessary. Q2-Q3 prints will reveal which path Cosan is on.

Sell-Side View

The sell-side framework on Cosan is uniformly cautious: rating-agency negative outlook, Ágora’s reduced price target, and strategic-shareholder positioning (BTG Pactual + Perfin as recent capital-injection participants) all signal recognition of the multi-quarter rehabilitation arc ahead. The Q1 print broadly validates the framework — operational metrics confirm portfolio quality while balance-sheet metrics confirm continued pressure.

What Happens Next for Cosan

Raízen restructuring outcome: June 6 legal deadline for extrajudicial agreement approaches. Creditors demand R$8 billion ($1.58 billion) capital + Ometto ouster as chairman. Resolution will determine final Cosan equity-pick-up trajectory.

Dividend inflow recovery: Compass IPO completion changes dividend dynamics. Q2 will reveal initial post-IPO dividend stream from Compass to Cosan. Rumo dividend continuity also key.

Selic easing path: Each 100 basis points of Copom easing compresses Cosan‘s financial expense by approximately R$115 million ($23 million) annualised. Brazilian rate trajectory through 2026 toward 12-13 percent is the macro variable.

Additional asset monetisation: Vale stake (~4 percent), further Rumo or Compass stake reductions, or Moove monetisation all remain optionalities if balance-sheet pressure intensifies. Cosan has demonstrated willingness to act.

S&P rating action: Negative outlook since Q4 2025. Rating-agency response to Q1 print and Raízen restructuring outcome could trigger formal downgrade or stabilisation — material for cost of capital trajectory.

Frequently Asked Questions

How much did Cosan lose in Q1 2026?

Cosan reported Q1 2026 net loss of R$1.58 billion ($313 million), narrowing 11 percent from the R$1.79 billion ($355 million) loss in Q1 2025. The loss was impacted by approximately R$1 billion ($198 million) of non-recurring charges from pre-liquidation of bonds maturing in 2029, 2030 and 2031 — costs that flowed through both the net financial expense and deferred-tax lines.

Despite the bottom-line loss, adjusted consolidated EBITDA jumped 60 percent year-on-year to R$3.34 billion ($661 million) as all five operational subsidiaries delivered improvements. Consolidated net revenue fell 7 percent to R$9.03 billion ($1.79 billion). Net financial result was negative R$1.09 billion ($216 million), worsening 51 percent year-on-year, while net debt at holding level closed at R$11.5 billion ($2.28 billion) — up 18 percent quarter-over-quarter but down 34 percent year-on-year.

How is each Cosan subsidiary performing?

All four consolidated subsidiaries delivered Q1 2026 operational growth. Rumo (rail logistics) was the standout: EBITDA R$1.74 billion ($345 million), up 7 percent year-on-year, with volume +25 percent driven by North-operation grain flows. Compass (natural gas distribution) EBITDA reached R$1.33 billion ($263 million), up 2 percent reported but 12 percent adjusted for LNG-cargo timing. The Compass IPO completed during Q1 generated R$2.1 billion ($416 million) net to Cosan.

Moove (lubricants) EBITDA was essentially flat at R$236 million ($46.7 million) despite 10 percent volume growth, with margin compression to 9.6 percent and leverage reduced to 1.3x. Radar (agricultural land) was the only decliner: EBITDA fell 27 percent to R$103 million ($20.4 million), pressured by TRS sugar and soybean price declines plus absence of Q1 2025 asset-sale gains.

Raízen (sugar, ethanol, fuel distribution — JV with Shell) carrying value was already written to zero at Q4 2025; the company filed Brazil’s largest extrajudicial restructuring during Q1 2026.

What is the Raízen situation affecting Cosan?

Raízen, the joint venture between Cosan (44 percent) and Shell (44 percent) created in 2011 and once the crown jewel of Brazil’s energy transition story, filed Brazil’s largest-ever extrajudicial restructuring covering R$55.3 billion ($10.95 billion) in net debt. Cosan had already written Raízen’s carrying value to zero at Q4 2025, meaning Q1 2026 does not absorb further direct impairment.

The Raízen restructuring has escalated from financial restructuring to corporate governance battle. Creditors have demanded approximately R$8 billion ($1.58 billion) in fresh capital — more than double the R$4 billion ($792 million) Shell and Ometto previously committed — and the removal of Rubens Ometto as Raízen chairman as a condition. Up to R$16 billion ($3.17 billion) in debt may be converted into equity, potentially diluting Cosan to a minority stake and handing Shell or creditors majority control.

What is Cosan and who controls it?

Cosan S.A. (B3: CSAN3 / NYSE: CSAN) is one of Brazil’s largest infrastructure-and-energy holdings, controlled by founder and chairman Rubens Ometto. The conglomerate operates five core verticals: Raízen (sugar, ethanol, fuel — JV with Shell), Compass (natural gas distribution including Comgás), Rumo (Brazil’s largest rail logistics operator), Moove (lubricants exported to over 40 countries), and Radar (agricultural land management).

CEO Marcelo Martins leads operations. The November 2025 capital injection of R$10 billion ($1.98 billion) from BTG Pactual and Perfin reset the holding’s capital structure following years of Raízen-driven cash-flow deterioration. Cosan offers foreign-investor access through both B3 (CSAN3) and NYSE (CSAN) listings, providing one of the most direct exposures to Brazilian infrastructure consolidation. Ágora Investimentos maintains a R$11 ($2.18) DDM-based price target against recent ~R$5.66 ($1.12) trading levels.
