IG4 Eyes Control of Debt-Laden Raizen — Can a New Owner Rescue a Company Drowning in R$65 Billion of Obligations?

IG4 Closes In on Raizen — Can a Distressed-Debt Play Save Brazil's Biggest Ethanol Maker or Will Shareholders Get Wiped Out?

Shares of Raízen surged 8.8% to BRL 0.37 on October 9 after fresh reports indicated private equity firm IG4 Capital is nearing a binding deal to seize control of the sugar-and-ethanol giant through its sprawling debt restructuring — the largest out-of-court process in Brazilian history.

• A Buyout Firm Wants to Own Raízen by Buying Its Debts, Not Its Stock. IG4 aims to acquire 50% plus one of the credits that are expected to be converted into equity, a move that could give the firm control of Raízen after the financial restructuring.

IG4 made a non-binding offer two months ago and is now preparing a definitive proposal targeting more than 50% of the credits to secure control. The mechanism is simple: under the restructuring plan, 45% of Raízen's debt would be converted into shares at BRL 0.25 per share, giving creditors more than 80% of the company. If IG4 buys a majority of that converting debt, it effectively becomes the new boss — without ever launching a traditional takeover bid.

• Existing Shareholders Face Massive Dilution No Matter What. The plan includes conversion of a portion of affected claims into equity and a capital increase of R$3.5–4.0 billion from Shell and potentially Aguassanta, and implementation "may result in significant dilution of the interest currently held" by Cosan.

Raízen ended 2025 with negative shareholders' equity of R$1.13 billion. At BRL 0.37, the stock is still 96% below its five-year peak. Even the current bounce prices shares above the BRL 0.25 conversion rate, meaning today's buyers are paying a premium to what creditors will pay for their new shares.

• IG4 Wants Only Half the Company. The restructuring plan envisions splitting Raízen — a Shell-Cosan joint venture — into separate fuel-distribution and sugar-and-ethanol units, with IG4 interested in the latter. That split could unlock value if the fuel business, with thousands of gas stations, fetches a standalone valuation — but it also concentrates IG4's bet on a commodity operation battered by high interest rates, strategically disastrous expansion bets, and devastating forest fires that ravaged sugarcane yields.

• No Signed Deal Means Risk Remains Real. The binding offer is expected in coming weeks, negotiations remain ongoing, and the operation still depends on creditor approval and the evolution of the restructuring.

IG4 is aiming to finalize by the end of March 2027. If creditors reject the terms or IG4 fails to amass a majority stake, the rally could evaporate as fast as it appeared.
