• Price range disclosed: $100.06 to $100.55 per share; the filing notes the weighted average and says per-price breakdown is available upon SEC request (Footnote F2).
• Footnote (F1): Sale was executed pursuant to a Rule 10b5-1 trading plan adopted August 21, 2025.
• Shares owned after transaction: not disclosed in the provided excerpt of the filing.
• No indication in the filing excerpt of late reporting or additional derivative transactions.

Context A Rule 10b5-1 plan means the sale was pre-authorized under a trading plan adopted previously, which is commonly used to schedule transactions and can reduce the implication that the insider traded on non-public information. For retail investors, purchases tend to be more informative than routine sales; this single small sale ($~10k) is a routine insider disposition unless paired with other, larger insider activity.
