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.
