GPK shares fell from the mid-$25 range before the first corrective disclosure to $12.42 following the third alleged in the complaint. The lead plaintiff deadline is July 6, 2026.

February 4, 2025 — Optimistic Guidance Sets the Stage

Graphic Packaging reported FY 2024 results and issued FY 2025 guidance projecting net sales of $8.7 billion to $8.9 billion, adjusted EBITDA of $1.68 billion to $1.78 billion, and adjusted EPS of $2.53 to $2.78. Management characterized results as "consistent" and "profitable," the securities action alleges, while downplaying volume challenges and rising inventory levels that were already pressuring operations.

May 1, 2025 — First Corrective Disclosure Shocks the Market

The Company reported Q1 2025 results revealing a 6.2% revenue decline and slashed its full-year guidance across every metric. Net sales expectations dropped to $8.2 billion to $8.5 billion. Adjusted EBITDA guidance fell to $1.4 billion to $1.6 billion. Adjusted EPS guidance dropped to $1.75 to $2.25. Bloomberg reported GPK shares "plunge[d] as much as 16%, the most intraday since October 2018, after the company cut its adjusted Ebitda guidance for the full year." Shares closed down $3.94 at $21.37.

July 29, 2025 — Brief Uptick in Guidance Maintained Confidence

Graphic Packaging modestly raised or otherwise narrowed its FY 2025 guidance ranges, as claimed in the lawsuit, citing "actual first half performance" and better-than-expected promotional volumes. The filing contends this temporary positive revision sustained artificially inflated stock prices while underlying inventory and demand problems persisted.

October 9, 2025 — CFO Resignation Announced

The Company disclosed the resignation of its Chief Financial Officer, effective November 7, 2025. The action alleges this departure occurred while significant operational challenges remained undisclosed to investors.

Chronology of Material Events

• February 4, 2025: FY 2025 guidance issued at $1.68B-$1.78B adjusted EBITDA; management touted "strong and steady" business model
• May 1, 2025: Q1 miss and first major guidance cut; GPK fell 15.57% in one session
• July 29, 2025: Modest guidance raise for sales, narrowing for earnings; management stated demand was "strong" and inventory reduction was on track
• October 9, 2025: CFO departure announced
• December 8, 2025: Accelerated inventory reduction, additional $15M curtailment costs, guidance cut, and CEO departure; GPK fell 8.66%
• February 3, 2026: Q4 EPS miss, $130M projected 2026 EBITDA hit from inventory actions, new CEO announced "comprehensive review"; GPK fell 15.97% to $12.42

December 8, 2025 — CEO Departs as Guidance Cut Again

Graphic Packaging announced it would accelerate inventory reduction plans originally scheduled for 2026 into Q4 2025, with an additional $15 million production curtailment impact. Adjusted EBITDA guidance was cut from the previously cut $1.4 billion to $1.45 billion down further to $1.38 billion to $1.43 billion. The same day, the CEO's departure was announced, effective December 31, 2025. Shares fell $1.35, or 8.66%, on December 9.

February 3, 2026 — Final Disclosure Completes the Collapse

Q4 non-GAAP EPS of $0.29 missed estimates by $0.06. The Company projected a $130 million negative EBITDA impact in 2026 from inventory actions and a $100 million accrual for incentive compensation. The new CEO initiated a "comprehensive review" of operations and organizational structure, as set forth in the complaint, confirming the weakness of the existing business model. GPK closed at $12.42, down $2.36 or 15.97%.
