What Happened?
On May 1, 2025, Graphic Packaging released its first quarter 2025 financial results, reporting non-GAAP EPS of $0.51, missing consensus estimates by $0.07, and revenue of $2.12 billion, representing a 6.2% year-over-year decline, and missing consensus estimates by $10 million. Further, the Company significantly lowered its previously issued 2025 guidance due to “an expectation of a 2% volume decline and $80 million of input cost inflation at the midpoint”, as well as “higher macroeconomic and consumer spending uncertainty.”

On this news, Graphic Packaging’s stock price fell $3.94, or 15.6%, to close at $21.37 per share on May 1, 2025, thereby injuring investors.

Then, on December 8, 2025, Graphic Packaging disclosed that it planned to “accelerate certain inventory reduction plans into the fourth quarter that were originally planned for 2026”, and that “[p]roduction curtailment is expected to impact fourth quarter operating results by $15 million.” The Company also further lowered its 2025 guidance. The same day, the Company also announced that its President and CEO had “mutually agreed with [its] Board of Directors to step down from his role.”

On this news, Graphic Packaging’s stock price fell $1.35, or 8.7%, to close at $14.23 per share on December 9, 2025.

Then, on February 3, 2026, Graphic Packaging released its fourth quarter and full year 2025 financial results, missing consensus estimates due to lower volumes, increased costs, and inventory reduction.

On this news, Graphic Packaging’s stock price fell $2.36, or 16%, to close at $12.42 per share on February 3, 2026, thereby injuring investors further.
