• This was an open-market sale (code S). Sales by insiders are common and can reflect many reasons (liquidity, diversification, taxes) and do not, by themselves, indicate company performance. Purchases are typically given more weight by investors seeking insider conviction. Check the full Form 4 for exact post-transaction ownership and any additional disclosures.
