The deal will see Boeing take 80 percent of the civilian business of Embraer, which is the third-biggest plane maker in the world

Brazilian aircraft manufacturer Embraer on Thursday signed an agreement for the sale of its commercial divison to Boeing—and set the date for a shareholders meeting to approve the tie-up on February 26.

Despite initital reservations, Brazil's President Jair Bolsonaro already gave the —which will create a joint entity valued at $5.2 billion—his approval earlier this month.

On top of getting shareholders on board, the agreement must also be approved by regulators, among other things. If all progresses without delay, the companies expect to conclude negotiations by the end of 2019.

Under the deal with Boeing, the US company will take 80 percent control of Embraer's civilian business, putting it in a position to offer commercial planes with up to 150 seats.
