Director NEVENS THOMAS MICHAEL sold 8,554 shares of CIEN at $224.66 for $1.9M, reducing stake by 47.6%
Director Thomas Michael Nevens sold 8,554 shares at $224.66 on 2025-12-15, representing a 47.6% reduction in his holdings from 17,976 to 9,422 shares. The sale occurred near the stock's 52-week high of $242.37, just $17.71 below peak levels, and at a significant premium to the current price of $203.90. The stock has delivered strong momentum over the prior 90 days (+47.7%) and 30 days (+6.3%), while the company shows healthy fundamentals with 18.8% annual revenue growth and quarterly revenue of $1.2B, though the elevated P/E of 234.37 reflects limited near-term earnings relative to valuation. The substantial reduction in director holdings warrants examination of whether this reflects a material portfolio shift or other circumstances, particularly given the proximity to 52-week highs.
