(Reuters) -Electric-pickup maker Rivian on Tuesday stuck to a 2024 production forecast well below Wall Street targets and reported a wider-than-expected first-quarter loss as it ended a weeks-long manufacturing halt. Rivian shares fell 6% in after-hours trading as the muted forecast drew questions from some analysts about demand for its pricey R1S SUVs and R1T pickups. High inflation has soured consumer sentiment for electric vehicles, with hybrids gaining sales traction.
