Item 4. Controls and Procedures

We performed an evaluation of the effectiveness of our disclosure controls and procedures as of September 28, 2025. The evaluation was performed with the participation of senior management of each business segment and key corporate functions, under the supervision of the Chief Executive Officer (CEO) and Chief Financial Officer (CFO). Based on this evaluation, the CEO and CFO concluded that our disclosure controls and procedures were operating and effective as of September 28, 2025.

There were no changes in our internal control over financial reporting during the quarter ended September 28, 2025 that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Forward-Looking Statements

This Form 10-Q contains statements that, to the extent they are not recitations of historical fact, constitute forward-looking statements within the meaning of the federal securities laws, and are based on our current expectations and assumptions. The words “believe,” “estimate,” “anticipate,” “project,” “intend,” “expect,” “plan,” “outlook,” “scheduled,” “forecast” and similar expressions are intended to identify forward-looking statements. These statements are not guarantees of future performance and are subject to risks and uncertainties. Actual results may differ materially due to factors such as:

• our reliance on contracts with the U.S. Government, which are dependent on U.S. Government funding and can be terminated for convenience, and our ability to negotiate favorable contract terms;

• budget uncertainty, the risk of future budget cuts, the impact of continuing resolution funding mechanisms, the debt ceiling and government shutdowns, and changing funding and acquisition priorities;

• risks related to the development, production, sustainment, performance, schedule, cost and requirements of complex and technologically advanced programs, including the F-35 program;

• planned production rates and orders for significant programs, compliance with stringent performance and reliability standards, and materials availability, including government furnished equipment and rare earth minerals;

• the timing of contract awards or contract definitization, decisions by government customers to impose contract terms following undefinitized contract actions, achievement of performance milestones, customer acceptance of product deliveries, and receipt of customer payments;

• our ability to recover costs under U.S. Government contracts, the mix of fixed-price and cost-reimbursable contracts and the risks inherent in preparing estimates for fixed-price contracts (particularly for complex and technologically advanced programs);

• customer procurement and other policies, laws, regulations and executive actions that affect our and our industry’s, programs, future opportunities, and financial performance, including those relating to mission priorities, competing domestic and international spending, contracting terms (such as fixed-price requirements), treatment of contractor performance issues, and contractor access to competitive opportunities;

• performance and/or financial viability of key suppliers, teammates, joint ventures (including United Launch Alliance), joint venture partners, subcontractors and customers;

• economic, industry, business and political conditions including their effects on governmental policy;

• the impact of inflation and other cost pressures;

• government actions that restrict or prevent the sale or delivery of our products (such as delays in approvals for exports requiring Congressional notification);

• foreign policy and international trade actions taken by governments such as tariffs, sanctions, embargoes, export and import controls, buying preferences, and other trade restrictions;

• our success expanding into and doing business in adjacent markets and internationally and the risks posed by international sales, including potential effects from fluctuations in currency exchange rates;

• changes in non-U.S. national priorities and government budgets and planned orders;

• the competitive environment for our products and services;

• our ability to develop and commercialize new technologies and products, including emerging digital and network technologies and capabilities;

• our ability to benefit fully from or adequately protect our intellectual property rights;

• our ability to attract and retain a highly skilled workforce and the impact of work stoppages or other labor disruptions;

• cyber or other security threats or other disruptions faced by us or our suppliers;

• our ability to implement and continue, and the timing and impact of, capitalization changes such as share repurchases, dividend payments and financing transactions;

• the accuracy of our estimates and projections;

• changes in pension plan assumptions and actual returns on pension assets; cash funding requirements and pension annuity contracts and associated settlement charges;

• realizing the anticipated benefits of acquisitions or divestitures, investments, joint ventures, teaming arrangements or internal reorganizations, and market volatility affecting the fair value of investments that are marked to market;

• our efforts to increase the efficiency of our operations and improve the affordability of our products and services, including through digital transformation and cost reduction initiatives;

• the risk of an impairment of our assets, including the potential impairment of goodwill and intangibles;

• the availability and adequacy of our insurance and indemnities;

• compliance with laws, regulations, policies, and customer requirements relating to environmental matters;

• the impact of public health crises, natural disasters and other severe weather conditions on our business and financial results, including supply chain disruptions and delays, employee absences, and program delays;

• changes in accounting, U.S. or foreign tax, export or other laws, regulations, and policies and their interpretation or application, and changes in the amount or reevaluation of uncertain tax positions; and

• the outcome of legal proceedings, bid protests, environmental remediation efforts, audits, administrative reviews, government investigations or government allegations that we have failed to comply with law, other contingencies and U.S. Government identification of deficiencies in our business systems.

These are only some of the factors that may affect the forward-looking statements contained in this Form 10-Q. For a discussion identifying additional important factors that could cause actual results to differ materially from those anticipated in the forward-looking statements, see our filings with the U.S. Securities and Exchange Commission (SEC) including, but not limited to, “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and “Risk Factors” in our 2024 Form 10-K and subsequent Quarterly Reports on Form 10-Q. Our filings may be accessed through the Investor Relations page of our website, www.lockheedmartin.com/investor, or through the website maintained by the SEC at www.sec.gov. Information contained on or made available through our website or other websites mentioned in this Form 10-Q is not incorporated into and is not a part of this Form 10-Q, and any references to our website are intended to be inactive textual references only.

Our actual financial results likely will be different from those projected due to the inherent nature of projections. Given these uncertainties, forward-looking statements should not be relied on in making investment decisions. The forward-looking statements contained in this Form 10-Q speak only as of the date of our filing. Except where required by applicable law, we expressly disclaim a duty to provide updates to forward-looking statements after the date of this Form 10-Q to reflect subsequent events, changed circumstances, changes in expectations, or the estimates and assumptions associated with them.

PART II. OTHER INFORMATION

ITEM 1. Legal Proceedings

We are a party to litigation and other proceedings that arise in the ordinary course of our business, including matters arising under provisions relating to the protection of the environment, and are subject to contingencies related to certain businesses we previously owned. These types of matters could result in fines, penalties, cost reimbursements or contributions, compensatory or treble damages or non-monetary sanctions or relief. We believe the probability is remote that the outcome of each of these matters will have a material adverse effect on the company as a whole, notwithstanding that the unfavorable resolution of any matter may have a material effect on our net earnings and cash flows in any particular reporting period. We cannot predict the outcome of legal or other proceedings with certainty.

We are subject to federal, state, local and foreign requirements for the protection of the environment, including those for discharge of hazardous materials and remediation of contaminated sites. Due in part to the complexity and pervasiveness of these requirements, we are a party to or have property subject to various lawsuits, proceedings and remediation obligations. The extent of our financial exposure cannot in all cases be reasonably estimated at this time.

For more information regarding matters referred to above, including current estimates of the amounts that we believe are required for remediation or clean-up to the extent estimable, see “Note 7 - Legal Proceedings and Contingencies — Legal Proceedings and Environmental Matters” included in our Notes to Consolidated Financial Statements in this Form 10-Q, which is hereby incorporated by reference. For additional information and a description of previously reported matters, see also “Critical Accounting Policies – Environmental Matters” in “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and “Note 14 – Legal Proceedings, Commitments and Contingencies,” in our 2024 Form 10-K.
