Context

• These transactions primarily reflect RSU vesting, tax withholding via share-sale, an open-market sale of a portion of the vested shares, and internal transfers/gifts among Siebel-controlled entities. Gifts and inter-entity transfers do not necessarily indicate market sentiment.
• As a 10% owner with holdings held through trusts and asset-management entities (see F4–F8), Siebel’s reported moves are organizational and tax/estate related as much as personal trading.
• For derivative/RSU activity: RSUs convert to common shares on settlement (F1); the automatic withholding and sale is a common way to cover taxes rather than a separate voluntary sale.
