Evidence & confidence

Form 4 is a primary disclosure, but the transaction size is modest for a mid‑cap; typical market reaction to director sales of this magnitude is limited.

Market effects

Minimal impact on the networking equipment sector; no broader industry signal.

U.S. market only; no regional ripple effect.

Low; the filing is company‑specific and does not affect global markets.
