Mark W Kowlzan (CEO) sold 9,266 shares ($2.0M) at $217.08; maintains 473.6K shares. Stock -12.6% from 52-week high.

Mark W Kowlzan, as Chairman & CEO, sold 9,266 shares (9.3K shares) on 2026-05-27 for a total value of $2,011,426.22, reducing his holdings by 1.9% to 473.6K shares. His cross-ticker track record shows 5 prior sells with a 90-day well-timed rate of 100.00%, and at PKG specifically, all 5 prior sells (conducted between March 2024 and September 2025) were well-timed at the 90-day mark, with post-sale declines ranging from 1.7% to 13.3%. The current stock price of $218.14 is 12.6% below the 52-week high of $249.51 and has declined 2.0% over the past 30 days and 6.0% over the past 90 days. While the transaction is modest relative to his total holdings and the company's fundamentals remain solid (annual revenue growth of 7.2%, P/E of 26.22), the consistency of his prior well-timed exits at this ticker and his demonstrated pattern across holdings suggests this sale warrants monitoring for potential weakness ahead.

CEO Kowlzan sold 25,000 PKG shares at $215.97 on 9/11/25; stock down 14.9% from 52-week high, 4 of 4 prior PKG sales showed negative 90-day returns.

Mark Kowlzan, Chairman & CEO, sold 25,000 shares (25.0K shares) of Packaging Corp of America at $215.97 on 2025-09-11 for $5,399,250.00, reducing his holdings to 437,378 shares (437.4K shares). The sale occurred when PKG traded at -14.9% from its 52-week high of $248.85, and the stock has gained 9.5% over the 30-day period leading up to the sale. His same-ticker history shows a notable pattern: all 4 prior sales at PKG (2024-11-08, 2024-11-07, 2024-11-06, and 2024-03-04) delivered negative 90-day returns of -11.7%, -12.2%, -13.3%, and -1.7% respectively, indicating a 100% well-timed track record at this ticker. His cross-ticker track record across all open-market activity reports a 90-day well-timed rate of 100.00% on 4 prior sells, with an average 90-day return of -9.7%, further corroborating a pattern of selling before declines. The stock is currently trading at $211.81, already 1.8% below the transaction price, and the company's strong fundamentals (annual revenue growth of +7.4%, P/E of 21.08, $2.2B quarterly revenue) provide no apparent distress signal. The convergence of depressed valuation positioning relative to the 52-week range and the insider's historical pattern of executing sales ahead of subsequent losses warrants monitoring of near-term price action to assess whether this transaction again precedes a decline.

PKG CEO Kowlzan sells 66,640 shares for $15,995,682.51 across 3 days; near 52-week high of $241.59

CEO Mark W Kowlzan executed 3 separate sales totaling 66,640 shares for $15,995,682.51 at a blended average price of $240.03 during November 6–8, 2024, reducing his holdings by 13.6% from 490,115 to 423,475 shares. The transactions occurred near the 52-week high of $241.59 (current price $240.59 is -0.4% from that peak), following a 30-day rally of +11.2% and a 90-day gain of +24.0%. His cross-ticker track record shows 1 prior sell with a 90-day well-timed rate of 100.00%, and his only prior PKG sale on 2024-03-04 was also well-timed (90d return -1.7%), establishing a pattern of selling at strategically positioned moments. The company's fundamentals show revenue of $2,182,400,000.00 with net income of $238,100,000.00 but annual revenue growth contracted -8.0% year-over-year, and the P/E of 27.94 sits elevated relative to historical norms. The sale's magnitude, timing near recent highs following sustained gains, and the insider's consistent execution history merit investor attention.
