The lawsuit alleges that (i) Graphic Packaging was experiencing, <em>inter alia</em>, significant inventory management issues, as well as significantly reduced demand and volumes and increased costs; (ii) the Company 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; (iii) the Company likewise overstated the strength and sustainability of the Company's business model and operations, as well as its ability to weather ongoing macroeconomic headwinds; and (iv) accordingly, the Company's previously issued FY 2025 financial guidance was unreliable and/or unrealistic.</p>  <p align="justify">On May 1, 2025, Graphic Packaging issued a press release reporting its first quarter 2025 financial results. Among other results, the press release reported 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." On this news, the price of Graphic Packaging shares declined by $3.94 per share, or approximately 16%, from $25.31 per share on April 30, 2025 to close at $21.37 on May 1, 2025.</p>  <p align="justify">On December 8, 2025, Graphic Packaging issued a press release announcing that it "plans to accelerate certain inventory reduction plans into the fourth quarter that were originally planned for 2026", and that "[p]roduction curtailment is expected to impact fourth quarter operating results by $15 million, which is in addition to the $15 million relating to" certain earlier-announced curtailments. The Company further revealed that it had negatively revised its FY 2025 financial guidance again, now expecting its adjusted EBITDA "to be in the range of $1.38 billion to $1.43 billion" significantly below its previously revised guidance of $1.4 billion to $1.45 billion and adjusted EPS "to be in the range of $1.75 to $1.95" significantly below its previously revised guidance of $1.80 to $2.00. In a separate press release issued the same day, Graphic Packaging announced that Defendant Doss had "mutually agreed with [its] Board of Directors to step down from his role [as President and CEO] and as a director effective December 31, 2025." On this news, the price of Graphic Packaging shares declined by $1.35 per share, or approximately 9%, from $15.58 per share on December 8, 2025 to close at $14.23 on December 9, 2025.</p>  <p align="justify">Then, on February 3, 2026, Graphic Packaging issued a press release reporting its fourth quarter and FY 2025 financial results. Among other results, Graphic Packaging reported non-GAAP EPS of $0.29, missing consensus estimates by $0.06. The Company attributed its disappointing earnings results to, <em>inter alia</em>, lower volumes, increased costs, and inventory reduction. Further, Graphic Packaging projected a meaningful decline in adjusted EBITDA in 2026, citing "a $130 million negative impact from actions taken to reduce inventory and generate [FCF], an approximately $100 million accrual (non-cash in 2026) for a return to more normal incentive compensation, January weather and production impacts, and other largely offsetting operating items." In the same press release, Graphic Packaging&#39;s new President and CEO, Robbert Rietbroek, announced that he had "initiated a comprehensive review of our organization structure, operations, and footprint," among other aspects of the Company's business. On this news, the price of Graphic Packaging shares declined by $2.36 per share, or approximately 16%, from $14.78 per share on January 30, 2026 to close at $12.42 on February 3, 2026.</p>  <p align="center">[<a href="https://www.globenewswire.com/Tracker?data=h0z3Hs8Jv2g4mKOaKp32aG4Lr40yByJBIPuAMQV9_noHJDc-zohuILYc1a_KjraJfPSl2mo5GLGr0-3R31vTANtvQ05OWcSrb7PbfWPbhLxSFQ4xp0_7OLO5-Nq4_XP5QYXvg_F-GT7LA_LW5mQ2QHzfrkd7usuYyuZsyDptCy89dOQZcuhA1KPVaYGC7kEk" rel="nofollow" target="_blank">CLICK HERE TO LEARN MORE ABOUT THE CLASS ACTION</a>]</p>  <p align="justify"><strong>What Should I Do?</strong></p>  <p align="justify">If you purchased or otherwise acquired Graphic Packaging securities, have information, or would like to learn more about this investigation, please contact <a href="https://www.globenewswire.com/Tracker?data=JDOev8INRLWfsX8HXCHGHB-iLbPG3dbrFgSItvSITSk9ntxOg29G3tpHoNmlpZ030mujTNT212lrhupAObR7FCdjlSesMFNpxyqpZe06iy6rXbdo_NezhrqCy8brxt3H" rel="nofollow" target="_blank">Lauren Molinaro</a> of <a href="https://www.globenewswire.com/Tracker?data=KYCr6CG33BN8vUkysn5XxQ7P5rs2AkGxAh0d22o__fAWtsqnr8IKTTAHM7mRmGJ2scFMjGKm1rCwakpCbeFopwnRdJ0O2hbfBAGzFl22mkY=" rel="nofollow" target="_blank">Kirby McInerney LLP</a> by email at <a href="https://www.globenewswire.com/Tracker?data=doakGRi6Bvb1OTVfM7KGMEl42XSJAad7c-iBXh0klsKbWuaismFr-zLnjjaYCVZHR6f1_PQ6iIuFwfw6gh3Do49JEJE3-aoVDSd_N2gH86qtIkKlE8Z-YS3OA_jc81t_" rel="nofollow" target="_blank">investigations@kmllp.com</a>, or fill out the contact form below, to discuss your rights or interests with respect to these matters at no cost.</p>  <p align="center">[<a href="https://www.globenewswire.com/Tracker?data=iZXn9ZjrM4AbspzixU3_0yY6EM_LhrCPGO19Ytlza-Jup_WUZ9CP9lOUBsjLjbcMbOrXzyeakr_9P8GURWLa7QmkgVQcyAGhFjfzdfNX1aM2nfPKaQ5gBCrcQ9Kh_bLDdPsJBv5pMweDx0Aq1nbUlQ==" rel="nofollow" target="_blank">WHAT IS A SECURITIES CLASS ACTION?</a>]</p>  <p align="justify"><a href="https://www.globenewswire.com/Tracker?data=KYCr6CG33BN8vUkysn5XxdavC5NkqA-ZQP9GpRwXQ3yvsO7fNB9LNn8gvn7crmJ4-lqbKMJkYVzysqYvIxynCZNPbaIJQj8A4c_ajZMRozY=" rel="nofollow" target="_blank">Kirby McInerney LLP</a> is a New York-based plaintiffs' law firm concentrating in securities, antitrust, whistleblower, and consumer litigation.
