SunPower Inc. (SPWR) shares experienced a significant decline of 10.6% in after-hours trading.

This market volatility followed the company's submission of a filing to the U.S. Securities and Exchange Commission (SEC). The document disclosed that SunPower Inc. had identified significant errors in some of its 2025 interim financial statements and therefore decided to restate these reports. The financial data correction is expected to impact certain previously announced interim results. The market reacted quickly to the news, causing the share price to drop sharply after regular trading hours.
