Cosan Leaves the New York Stock Exchange on September 18

Cosan is taking its shares off the New York Stock Exchange after years of a dual listing. What happens to the receipts themselves is the part worth reading twice.

A delisting sounds final. In this case the American receipts survive it, and an earlier filing said the opposite.

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 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 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 the first level, letting the receipts trade over the counter in the United States.

The later filing governs. Anyone working from the August language has stale information.

A first-level 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.

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 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 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 the Brazilian exchange.

That last point is the honest core of it. A second listing costs money and, in this case, was carrying little volume.

Cosan is a Brazilian holding company with interests in fuel distribution, sugar and ethanol , logistics, gas and land.

It reported a second-quarter net loss of R$320 million, about US$62.9 million, down 66% from R$946 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, about US$1.81 billion.

The company prepaid R$8.8 billion of debt principal in the first half, roughly US$1.73 billion.

It also signed a letter of intent to sell a port terminal for about R$300 million, or US$59 million, plus earn-outs.

Cosan’s holding in Raízen, its fuel and sugar joint venture with Shell, 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.

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.

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

For a Brazilian investor almost nothing changes. The shares trade where they always did.

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

The group runs Raízen with Shell, in sugar, ethanol and fuel distribution. That is its largest and most troubled holding.

Compass distributes natural gas and went to market in its own listing, raising about R$2.3 billion net for Cosan.

That is roughly US$452 million, and it 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.
