Why Rivian Stock Fell 12% in the First Half of 2026

Rivian's stock declined 11.9% in the first half of 2026 despite raising delivery guidance and launching its new R2 SUV. The decline was driven by analyst downgrades, a 28% drop in U.S. EV sales, widening losses ($427M adjusted EBITDA loss in Q1), and elimination of its 2027 EBITDA profitability goal. An 18% stock plunge followed a $1.2 billion capital raise announcement in July.
