RE:Warning EmbraerYes, Embraer appears to be struggling. Although Embraer competes head-to-head with BBD in Regional jets, that company has more focus on the smaller business jets. It sells a lot of Phenoms, but it doesn't have much to offer in the larger, luxury business jet segment, which has helped other manufacturers like Bombardier and Gulfstream (GD).
Embraer does convert one of its RJs into something it calls "the Legacy", but it isn't specifically designed as a business jet, and doesn't compete particularly well in this segment.
Bombardier's Globals, and Gulfstream's 550s and 650s are much more popular.
