This was a sale (not a purchase); sales by insiders can be routine and do not necessarily signal a change in view.

Key Details

• Transaction date and terms: 2026-06-26 — 250 shares sold at $62.01 (total ~$15,503).
• Filing: Form 4 filed 2026-06-30 (within the standard two-business-day reporting window).
• Shares owned after transaction: not specified in the provided filing.
• Footnote: sale was effected pursuant to a Rule 10b5-1 trading plan adopted on September 22, 2025.

Context
A 10b5-1 plan allows preplanned trades and is commonly used by insiders to avoid trading based on nonpublic information; sales under such plans are generally viewed as routine. The transaction size (~$15.5K) is relatively small, so investors should avoid overinterpreting it as a company-level signal.
