Yeah the hump (very big hump) is the US scope clauses right smack in the middle of their obvious NB growth path.

They can't market a 180-seater out of the blue... they would be crushed by both BCA and AB. Deliberately.

Their potential path would be to establish a customer base and product support niche in the 100-seat range and gradually sneak in bigger planes. But scope...

The US isn't the only place you can sell planes, but China will eventually build exportable NB's, and the non-US market is what they're going to target. So competition everywhere. I can't really blame Embraer for staying in their niche.
