• Tesla—the bellwether for mobility tech—saw its shares’ descent accelerate during the quarter, losing nearly half their value on concerns over slowing shipments, heightened competition, and CEO Elon Musk’s dalliance with Twitter. The New Year rang in more anxiety for investors as shipments missed expectations, and shares promptly dropped 12%.

• In contrast, Mobileye’s IPO, launched in one of the harshest IPO environments in years, was a relative success—albeit at a dramatically lower valuation than originally hoped for. Shares rose 21% through year end and now enjoy a frothy 47x EV/EBITDA multiple.

• Ford and VW shocked investors during the quarter when they pulled the plug on their multibillion-dollar investment in autonomous vehicle startup Argo.AI.

• In December, Toyota’s CEO proclaimed there is a “silent majority” in the auto industry that is doubtful of an EV-only future for automobiles.
