Why Brazil’s Cosan Is Leaving the NYSE but Keeping Its US Receipts

Brazilian conglomerate Cosan has spent 2026 cutting debt after writing down its stake in Raízen, its fuel venture with Shell, to zero. It is now ending its New York Stock Exchange listing, though its American receipts will keep trading.

Cosan filed on 8 September to withdraw its American depositary shares from the New York Stock Exchange. Their last day there is 18 September 2026, after which they keep trading over the counter, the company says.

Why This Matters

Cosan was founded in 1936 in Piracicaba, a sugar-cane town in São Paulo state, and is chaired by businessman Rubens Ometto. Today it is a holding company with interests in fuel distribution, sugar and ethanol, logistics, gas and land.

Its current American receipts were registered for trading on the New York Stock Exchange in March 2021, according to SEC records. American depositary shares, or ADSs, are certificates that let US investors own shares of a foreign company in dollars.

Leaving New York is therefore a retreat from the world’s deepest stock market, even if the shares keep trading at home. The move comes after a year in which Cosan has cut debt and sold assets to protect its balance sheet.

Much of that pressure traces back to Raízen, the fuel and sugar joint venture Cosan formed with Shell in 2010. Raízen merged the two companies’ Brazilian assets and listed its own shares in August 2021.

The Dates

Cosan’s board approved the withdrawal on 14 August 2026. It formally notified the New York Stock Exchange on 18 August.

The company filed the delisting form with the Securities and Exchange Commission, the US market regulator, on 8 September. The last day the receipts trade on the exchange is 18 September 2026.

Under the rules, a withdrawal takes effect ten days after that filing. Deregistration from the exchange follows about ninety days later.

Cosan has not published its own date for that final step. Those timings are what the rules provide, not company guidance.

The Detail Two Filings Disagree On

The August notice said the company had not arranged for the receipts to be listed or quoted anywhere else. The September notice says the opposite.

Cosan will keep its programme at Level I, the lowest tier, so the receipts trade over the counter. The later filing governs.

Anyone working from the August language has stale information. A Level I programme is the simplest kind.

It trades off-exchange, with lighter reporting and thinner liquidity. Cosan also remains a registered filer with the American regulator.

It has not filed to deregister entirely. That means US investors will still see its periodic reports on the regulator’s public database.

What Holders Have to Do

Nothing is required. No filing sets out a surrender or cancellation procedure, because the programme survives.

Holders can keep the receipts and trade them over the counter. They can also instruct the depositary bank to cancel them for ordinary shares in Brazil.

Each receipt represents four ordinary shares. That ratio is unchanged.

Nobody should report a forced conversion. That is not what is happening here.

The Reason Cosan Gives

The company describes the move as part of an objective to simplify and optimise its capital structure. It cites cost reductions and greater focus on its most strategically relevant business areas.

It also notes that trading in its shares is predominantly concentrated on B3, the São Paulo stock exchange. Cosan’s shares will stay listed on the Novo Mercado, B3’s segment with the strictest governance rules.

The honest core of it is cost. A second listing costs money and, in this case, was carrying little volume.

The Balance Sheet Behind the Decision

Cosan reported a second-quarter net loss of R$320 million (US$62.9 million), down 66% from R$946 million (US$186 million) a year earlier. Conversions use 5.0856 reais to the US dollar, the Banco Central closing rate for 8 September 2026.

Net debt at the holding level fell 47% year on year to R$9.2 billion (US$1.81 billion). The company prepaid R$8.8 billion (US$1.73 billion) of debt principal in the first half.

It also signed a letter of intent to sell a port terminal for about R$300 million (US$59 million), plus earn-outs. Earn-outs are extra payments that depend on how the business performs after the sale.

The Raízen Problem in the Background

Cosan’s holding in Raízen was written down to zero at the end of 2025. Raízen’s out-of-court restructuring plan was approved during the second quarter of 2026.

That is the single largest reason the group has spent this year cutting debt and selling assets. Raízen separately completed the sale of its Argentine business earlier this month, for US$1.42 billion.

What Cosan Actually Owns

Raízen, run with Shell in sugar, ethanol and fuel distribution, is the group’s largest and most troubled holding. Compass distributes natural gas and went to market in its own listing, raising about R$2.3 billion (US$452 million) net for Cosan.

That was one of the year’s main sources of cash for cutting debt. Rumo runs the country’s largest rail freight network, moving grain from the interior to the ports.

Radar holds farmland, and the group also has a stake in the mining company Vale. Together they make Cosan a holding company rather than an operator.

For a foreign reader that structure is the point. A loss at one arm does not describe the group, and a delisting does not describe the business.

What a Delisting Does and Does Not Signal

Leaving a foreign exchange is not the same as leaving public markets. Cosan remains listed in São Paulo.

Companies do this when the second listing costs more than it delivers in liquidity or visibility. No filing reviewed by The Rio Times links the delisting to a sale, a buyout or a change of control.

What It Means If You Hold the Receipts

For an American investor the practical change is real. Over-the-counter trading means wider spreads and less analyst coverage.

Foreign readers holding the receipts should check with their broker before 18 September. Some brokers restrict over-the-counter trading.

For a Brazilian investor almost nothing changes, because the shares trade where they always did. Investors who want the most liquid market can convert receipts into ordinary shares traded on B3.

What Is Not Yet Known

Cosan has not said how much the delisting will save each year. It has not published its own date for final deregistration from the exchange.

It is not known how liquid the over-the-counter receipts will be once New York trading ends. The final sale of the port terminal has not yet been signed.
