NEW YORK, June 25, 2026 /PRNewswire/ -- Faruqi & Faruqi, LLP, a leading national securities law firm, is investigating potential claims against Graphic Packaging Holding Company ("Graphic Packaging" or the "Company") (NYSE: GPK) and reminds investors of the July 6, 2026 deadline to seek the role of lead plaintiff in a federal securities class action that has been filed against the Company.

Faruqi & Faruqi is a leading national securities law firm with offices in New York, Pennsylvania, California and Georgia. The firm has recovered hundreds of millions of dollars for investors since its founding in 1995. See www.faruqilaw.com.

As detailed below, the complaint alleges that the Company and its executives violated federal securities laws by making false and/or misleading statements and/or failing to disclose that: (1) Graphic Packaging was experiencing, inter alia, significant inventory management issues, as well as significantly reduced demand and volumes and increased costs; (2) Defendants downplayed the true scope and severity of the foregoing issues, which were likely to, and did, have a material negative impact on the Company's business and financial results; (3) Defendants likewise overstated the strength and sustainability of the Company's business model and operations, as well as its ability to weather ongoing macroeconomic headwinds; (4) accordingly, the Company's previously issued FY 2025 financial guidance was unreliable and/or unrealistic; and (5) as a result, Defendants' public statements were materially false and misleading at all relevant times.

The court-appointed lead plaintiff is the investor with the largest financial interest in the relief sought by the class who is adequate and typical of class members who directs and oversees the litigation on behalf of the putative class. Any member of the putative class may move the Court to serve as lead plaintiff through counsel of their choice, or may choose to do nothing and remain an absent class member. Your ability to share in any recovery is not affected by the decision to serve as a lead plaintiff or not. 

Faruqi & Faruqi, LLP also encourages anyone with information regarding Graphic Packaging's conduct to contact the firm, including whistleblowers, former employees, shareholders and others.

Frequently Asked Questions (FAQ) for Investors Regarding the Graphic Packaging Holding Company Securities Class Action Lawsuit:

What is the Graphic Packaging securities fraud lawsuit about?

The Graphic Packaging securities fraud lawsuit is a federal securities class action alleging that Graphic Packaging Holding Company (NYSE: GPK) and its executives made false and misleading statements to investors by concealing significant inventory management issues, reduced demand and volumes, and increased costs, while overstating the strength and sustainability of the Company's business model and issuing unreliable financial guidance. As the truth emerged through a series of disclosures — including a May 1, 2025 Q1 earnings miss and sweeping downward revision to FY 2025 guidance, a December 8, 2025 announcement of accelerated inventory reductions, further guidance cuts, and the CEO's departure, and a February 3, 2026 Q4 earnings miss accompanied by a projected meaningful decline in 2026 adjusted EBITDA and the launch of a comprehensive business review — GPK's stock price fell sharply across each disclosure, causing significant cumulative losses for investors.
