Context

• These are planned sales under a 10b5-1 program, which typically executes pre-set instructions and can represent routine disposition rather than a real-time market view; the filing is factual and does not disclose motives.
• Purchases by insiders are generally considered more directly bullish than planned sales; here the activity is sales-only.
