• Price per share: $193.06
• Shares sold: 16,500 — Total proceeds: $3,185,490

Context
A sale under a prearranged 10b5-1 plan generally indicates the trades were scheduled in advance and should be interpreted as part of routine personal planning rather than a contemporaneous statement about ATI’s prospects. Purchases by insiders tend to carry more weight for signaling than sales; this filing is informational rather than directional.
