Overview

A class action lawsuit has been filed against Lockheed Martin Corporation (“Lockheed Martin” or the “Company”) and certain of the Company’s current and former senior executive officers alleging violations of the federal securities laws. Lockheed Martin’s common shares trade on the New York Stock Exchange (“NYSE”) exchange under the symbol “LMT.”

The Lockheed Martin class action lawsuit was brought on behalf of all persons and entities who purchased or otherwise acquired Lockheed Martin securities between January 23, 2024, and July 21, 2025, both dates inclusive (the “Class Period”).

Lockheed Martin is an aerospace and defense company principally engaged in the research, design, development, manufacture, integration and sustainment of advanced technology systems, products and services.

The Lockheed Martin class action lawsuit centers on a series of significant undisclosed risks and losses tied to the Company’s classified programs and other defense projects.

The lawsuit alleges that throughout the class period, Defendants made materially false and/or misleading statements and failed to disclose adverse facts about the Company’s operations, particularly regarding cost overruns and performance issues in its Aeronautics and Missiles and Fire Control segments.

On October 22, 2024, Lockheed Martin announced $80 million in losses on a classified Aeronautics program due to “higher than anticipated costs” and an additional reach-forward loss in its Rotary and Mission Systems segment. The Company’s stock dropped 6.12%, from $614.61 to $576.98 per-share, on heavy trading volume.

On January 28, 2025, Lockheed Martin revealed further pre-tax losses of $1.7 billion, including $555 million tied to its Aeronautics program and $1.3 billion in its Missiles and Fire Control business, stemming from “performance trends” and “program risks.” As a result, net earnings for 2024 fell to $5.3 billion ($22.31 per share) from $6.9 billion ($27.55 per share) in 2023. The stock declined 9.2%, closing at $457.45.

Finally, on July 22, 2025, Lockheed Martin disclosed an additional $1.6 billion in pre-tax losses on classified programs, including $950 million related to design, integration, and testing issues in its Aeronautics Classified program. The Company also recorded $570 million in losses for the Canadian Maritime Helicopter Program and $95 million for the Turkish Utility Helicopter Program. Net earnings dropped sharply to $342 million ($1.46 per share). The stock plunged 10.8%, closing at $410.74.

These disclosures, according to the lawsuit, revealed that Lockheed Martin had concealed critical information about its classified programs’ escalating costs and operational difficulties, which had been materially overstated to investors, ultimately causing significant financial losses.
