New York, New York--(Newsfile Corp. - May 10, 2026) - 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 truth began to emerge on May 1, 2025, when Graphic Packaging issued a press release reporting its first quarter ("Q1") 2025 financial results. Among other results, the press release reported Q1 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. The press release further revealed that the Company had negatively revised its previously issued FY 2025 net sales outlook to a range of $8.2 billion to $8.5 billion, significantly down from its prior guidance of $8.7 billion to $8.9 billion; its adjusted EBITDA outlook to a range of $1.4 billion to $1.6 billion, significantly down from its prior guidance of $1.68 billion to $1.78 billion; and its adjusted EPS outlook to a range of $1.75 to $2.25, significantly down from its prior guidance of $2.53 to $2.78. The Company blamed the negatively revised guidance on "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."
