TL;DR Insider sale of 16,989 POWI shares at $46.8588, leaving 67,787 shares owned — a routine disclosure without additional context.

The Form 4 documents a direct sale by Doug Bailey, VP Marketing, on 08/14/2025. The transaction and post-sale ownership are clearly stated, but the filing does not include reasons for the sale or any planned trading program. Without information on total outstanding shares or recent patterns of insider transactions, the market impact cannot be determined from this filing alone.
