[Form 4] Old Second Bancorp Inc Insider Trading Activity

Rhea-AI Filing Summary

SEC Form 4 – AngioDynamics (ANGO)

Laura Piccinini, SVP International, disposed of 3,074 common shares on 17 Jul 2025. The shares were automatically withheld at $8.74 per share (≈ $26.9 k) to satisfy tax obligations tied to the scheduled vesting of restricted stock units granted on 17 Jul 2024. After the exempt disposition, Piccinini continues to hold 69,355 directly owned shares. No derivative security activity was reported.

The transaction is classified under code “F,” indicating a tax-withholding event rather than an open-market sale, and therefore is generally viewed as administratively routine with limited impact on the company’s share supply or insider sentiment.

Insights

Financial Analyst

TL;DR: Routine tax-withholding share sale—neutral impact on ANGO.

The filing records an exempt disposition to cover payroll taxes upon RSU vesting. Only 3,074 shares (sub-$30 k value) changed hands, leaving the executive’s ownership largely intact at 69,355 shares. Such F-code transactions are administrative, do not represent discretionary selling pressure, and typically carry no valuation signal. Consequently, I view the event as non-impactful for investors.
