RIVIAN AFFIRMS PRODUCTIONS GOAL:

Rivian, an electric vehicle maker that went public last year with big ambitions to take on Tesla and others, said Wednesday that supply chain problems had hobbled it in the first quarter, but it stood by its production forecast for this year. The company’s shares have declined over 80 percent this year as investors have grown nervous about its prospects. Its share price rose in after-hours trading Wednesday as the quarterly results largely met forecasts. Rivian reported a loss of $1.6 billion in the quarter.
