Four months into a three-year plan meant to reinvigorate Nissan, CEO Makoto Uchida is already struggling.

On Thursday, Nissan slashed its operating-profit outlook to ?500 billion ($3.3 billion) for the year through March 2025, down from its prior forecast of ?600 billion ¡ª and far more than analysts had expected ¡ª due to weak sales in Japan and the United States.

The cut triggered two days of declines in the company¡¯s shares, with the stock falling as much as 11.2% over Thursday and Friday, on track for the biggest two-day fall since February.
