The transaction totals roughly $1.25 million. Following the sale, Greene still owns 93,661 shares directly. No derivative transactions were reported.

Negative

• Insider disposition: CEO sold 13,158 shares (~12% of personal stake), which can be perceived as a mild negative signal.

Insights

Securities Analyst

TL;DR: Small-to-moderate insider sale; signal mildly negative but not thesis-changing.

Greene’s divestiture equals about 12% of her direct holdings and < 0.01% of SO’s outstanding shares, limiting market impact. The $95 price is near recent trading ranges, hinting at opportunistic liquidity rather than fundamental concern. Absence of derivative hedges or concurrent purchases suggests a straightforward disposition. Insider sales can precede underperformance statistically, yet the partial nature and remaining 93.7k-share stake temper bearish interpretation. Overall impact: slight negative sentiment, not financially material to SO.
