Ecopetrol’s Brazil Takeover Stalls Over What Minorities Get Paid
Markets
Key Facts
—The escalation. On 7 July Brava told the market that Ecopetrol’s appeal has gone to the full board of Brazil’s securities regulator. The offer stays frozen.
—The two halves. Ecopetrol (NYSE: EC) agreed in April to buy 26% of Brava (B3: BRAV3) privately, then launched a public offer for 116,110,717 shares at R$23.00 ($4.47) to reach 51%.
—The size. The public leg alone is worth about R$2.67bn ($519m), roughly a quarter of the company.
—The objection. Regulator staff hold that the private contracts and the public offer are one indivisible control transaction, which triggers equal treatment.
—The law. Article 254-A obliges a buyer of control to offer minorities at least 80% of what the control block received.
—The asset. Brava, formed in 2024 from the 3R–Enauta merger, reported EBITDA of $806m and a 39% margin for 2025.
Colombia’s national oil company is being blocked in Brazil, and not by politics, antitrust or nationalism. The Ecopetrol Brava Energia takeover has stalled on a single question of company law: whether one buyer may pay two prices.
Brava told the market on the evening of the seventh of July that the regulator’s technical staff had held their ground. Ecopetrol’s appeal now goes to the full board of the Comissão de Valores Mobiliários, and the offer remains suspended until it rules.
Brava says it knows of no change to the terms already announced. What changes, if the board sides with the staff, is the price.

How the Ecopetrol Brava Energia deal was built
The structure has two legs. In April, according to Ecopetrol’s filing with American regulators, it signed private contracts to buy roughly twenty-six percent of Brava from three groups of large funds.
In May its Brazilian subsidiary launched a public tender on the São Paulo exchange for a further hundred and sixteen million shares, at twenty-three reais each, a premium of about twenty-one percent over the previous ninety days of trading.
Add the legs together and Ecopetrol reaches exactly fifty-one percent, which is control. The public leg is worth roughly two and two-thirds billion reais, a little over five hundred million dollars, and is meant to be paid with a bridge loan.
Ecopetrol’s case is that these are two separate transactions. The regulator’s registration superintendency holds that they are economically inseparable, a single acquisition of control dressed in two documents.
Why the distinction is worth hundreds of millions
Brazilian company law contains a protection called tag-along. Where control of a listed company changes hands, the buyer must offer the remaining voting shareholders at least eighty percent of the price paid for the control block.
The regulator’s own rulebook then defines a transfer of control, in Instruction 361, as the operation “or the set of operations” through which a third party, or a set of third parties representing the same interest, acquires control.
That phrase is the entire dispute. Read plainly, it captures exactly what Ecopetrol has done, and the staff are reading it plainly.
The same rulebook adds a catch-all. The regulator may impose a control tender whenever it finds that control has in fact been sold for money, whatever shape the paperwork takes.

The clause nobody has mentioned
There is a detail in Instruction 361 that changes the arithmetic of delay. In cash deals the offer price must equal at least eighty percent of the price paid to the controller, plus interest at the Selic rate.
That interest runs from the day the controller was paid to the day the public offer settles. Brazil’s policy rate has been near fifteen percent.
If the board sides with its staff, the April purchase becomes the reference point and the statutory floor beneath the minorities has been accruing since April. Every week Ecopetrol spends arguing makes the outcome it is arguing against more expensive.
That cuts both ways, and it explains the tone of the Colombian company’s response. It has expressed respectful disagreement, promised to appeal with maximum speed, and said it remains confident the offer will proceed as first proposed.
What is actually at stake for a foreign reader
Brava is not a small prize. Formed in 2024 from the merger of two Brazilian producers, it reported earnings before interest, tax, depreciation and amortisation of eight hundred and six million dollars for last year, on a margin of thirty-nine percent.
Colombia’s reserves are shrinking and its government is cool on new drilling, so Ecopetrol is buying production in a country where output still grows. That strategic logic is unchanged by the appeal.
The precedent is what matters. Win, and control of a Brazilian company can be assembled in two legs, one private and generous, one public and less so.
Lose, and that route closes for every acquirer that follows. For an investor pricing Brazil, a regulator willing to freeze a state-backed foreign bid over the treatment of small shareholders is a reassurance rather than a risk.
Why did the CVM suspend the Ecopetrol Brava Energia offer?
Its staff concluded that the private share purchases and the public tender form one control transaction, which would require minorities to be offered a price tied to what the large sellers received.
What happens if Ecopetrol loses the appeal?
It must amend the offer or see the registration cancelled. The statutory floor is eighty percent of the control price plus accrued interest, so the amendment would cost money.
Is the takeover dead?
No. The offer is frozen, not cancelled, and Brava says the announced conditions still stand pending the board’s decision.
