WST Sr. VP Annette Favorite Exercises Options, Sells 8,135 Shares

What Happened

• Annette F. Favorite, Senior Vice President & Chief HR Officer of West Pharmaceutical Services (WST), exercised stock-option/derivative awards and immediately sold the resulting shares on Sep 8, 2026.
• She exercised a total of 8,135 shares (2,817 + 2,818 + 2,500). The exercises required aggregate cash of $694,453 (strikes: $83.47 for 2,817 and 2,818 shares; $89.64 for 2,500 shares). The shares were sold in the open market at a weighted average price of $340.81, producing gross sale proceeds of $2,772,490. Net proceeds (sales minus exercise cost) were about $2,078,037.
• These transactions are sales (realizing gains) following option/award exercises — often a routine cashless-exercise and sell-to-cover or sell-to-liquidate event rather than an outright purchase (which would be a bullish signal).

Key Details

Context

• This is a cashless-type transaction: the insider exercised options (paying the strike) and then sold the resulting shares immediately in the open market. That pattern is typically used to realize gains or cover tax/strike obligations and is common among executives.
• Sales following exercises do not, by themselves, indicate a change in an insider’s long-term view of the company; purchases are generally more informative of bullish sentiment.
