Deadline Approaching for GPK Investors to Join Securities Class Action Amid Allegations of Mismanagement

GPK Class Action Deadline Notification

Levi & Korsinsky, LLP is bringing to the attention of investors in Graphic Packaging Holding Company (GPK) a critical deadline related to an ongoing securities class action. Shareholders who acquired GPK securities between February 4, 2025, and February 2, 2026, may have the opportunity to seek damages due to alleged mismanagement within the company. The deadline to file for lead plaintiff status is approaching on July 6, 2026.

Overview of Allegations

The heart of the securities class action revolves around claims of significant inventory mismanagement that purportedly resulted in more than $130 million projected losses in EBITDA for the fiscal year 2026. Investors have observed a troubling trend in GPK's stock prices, which experienced a sharp decline from $25.31 to $21.37, marking a notable drop of $3.94. Further corrective disclosures led to additional decreases, culminating in a stock price settlement of $12.42 on February 3, 2026.

Management consistently assured investors that high inventory levels were both intentional and temporary, attributing these to the introduction of a new recycled paperboard mill in Waco, Texas. However, the reality depicted by the lawsuit suggests that the adverse financial impacts were far more serious than conveyed to shareholders.

Yearly Revenue and Production Impacts

The lawsuit outlines how GPK's revenue suffered a 6.2% drop year-over-year, falling to $2.12 billion in Q1 2025. This was primarily due to declining volumes, which management had downplayed. Despite promises to maintain a balance between supply and demand, strategic rebalancing led to unexpected production cutbacks. As detailed in legal filings, the company faced a projected EBITDA hit of $15 million from fourth-quarter production curbs intended to tackle escalating inventory levels.

By the time Q4 2025 arrived, GPK had communicated an estimated loss of $130 million in EBITDA for 2026, indicating that inventory issues had only deepened. In December 2025, the company disclosed further curtailment costs amounting to $15 million, as inventory problems carried over from the planned production adjustments originally set for 2026.
