The consumer packaging giant Graphic Packaging Holding Company (NYSE: GPK) is confronting a securities fraud class action lawsuit. This follows multiple downward revisions to its financial guidance, resulting in a shortfall of over $350 million from its initial adjusted EBITDA target and a cumulative stock price decline exceeding 50%. The deadline for investors to apply to serve as lead plaintiff is July 6, 2026.

The suit was filed in the U.S. District Court for the Southern District of New York. It seeks to represent investors who purchased Graphic Packaging securities between February 4, 2025, and February 2, 2026. Defendants include the company and former executives such as ex-CEO Michael P. Doss and former CFO Stephen R. Scherger. They are accused of violating federal securities laws by making false and misleading statements regarding inventory management conditions, market demand, and cost changes.

Core Allegations of the Lawsuit

The complaint alleges that throughout the class period, Graphic Packaging downplayed significant inventory management issues, substantial demand declines, and rising costs. It further claims the company exaggerated the strength and sustainability of its business model. Based on these alleged misrepresentations, the company's previously issued financial guidance for fiscal year 2025 is charged as having been unreliable and unrealistic.

Revelations Through Corrective Disclosures

The truth allegedly emerged through a series of corrective disclosures. On May 1, 2025, the company reported first-quarter results with revenue of $2.12 billion, a 6.2% year-over-year decline, and non-GAAP earnings per share of $0.51, missing estimates by $0.07. It significantly lowered its full-year net sales guidance from a range of $8.7-$8.9 billion to $8.2-$8.5 billion. The adjusted EBITDA guidance was also reduced from $1.68-$1.78 billion to $1.4-$1.6 billion. The stock price plunged 15.57% that day, closing at $21.37.

On December 8, 2025, the company announced it would accelerate part of its inventory reduction plan, originally scheduled for 2026, into the fourth quarter, expecting a $15 million impact on operating results. Concurrently, it again lowered its full-year adjusted EBITDA guidance to a range of $1.38-$1.43 billion. The same day, it announced CEO Doss would step down. The share price fell another 8.66%.

On February 3, 2026, the company released its fourth-quarter and full-year results, posting non-GAAP earnings per share of $0.29, which was $0.06 below expectations. The new CEO announced a comprehensive review of the company's organizational structure, operations, and business portfolio. The stock dropped 15.97% that day, closing at $12.42. By this point, the share price had fallen more than 50% from highs above $25 during the class period. As of June 5, 2026, the price had further declined to $10.57, down over 53% from a year earlier.

Next Steps for Investors

Several law firms have announced their participation in this litigation. Investors who wish to serve as lead plaintiff must apply by the deadline of July 6, 2026.
