Tesla CEO Elon Musk apologized during a second-quarter earnings call on Wednesday for impoliteness towards Wall Street analysts during the prior earnings call.

During the first-quarter call in May, Musk cut off Toni Sacconaghi, senior technology analyst at Sanford C. Bernstein, dubbing his question on Model 3 gross margins "boring." He took a first question from Sacconaghi on Wednesday, and promptly apologized for his prior conduct.
