Analysis · KOP · Manufacturing

Officer James A. Sullivan has filed a Form 144 to sell 80,000 shares worth approximately $4.0 million, representing about 0.42% of outstanding shares. The sale comes just one day after Koppers reported a Q2 GAAP loss of $147.5 million, including a $215.8 million impairment for the Stickney shutdown, and narrowed full-year guidance. The stock is trading near its 52-week high, which may provide a favorable exit point. While the sale is not from a C-suite executive, it is a significant dollar amount and follows a period of net insider selling over the past 90 days, adding to a pattern of distribution.

At the time of this filing, KOP was trading at $51.24 on NYSE in the Manufacturing sector, with a market capitalization of approximately $985.4M. The 52-week trading range was $25.00 to $53.00. This filing was assessed with negative market sentiment and an importance score of 7 out of 10.
