- These were outright sales (code S) — sales are often routine portfolio/ liquidity transactions and do not necessarily indicate negative company-specific information.
- Tompkins is a reported 10% owner (a significant shareholder, not necessarily an executive), so sales may reflect large-holder rebalancing rather than insider sentiment.
- No derivative exercises, gifts, or tax-withholding transactions were reported in this filing.
