ITEM 9A. Controls and Procedures Evaluation of Disclosure Controls and Procedures We performed an evaluation of the effectiveness of our disclosure controls and procedures as of December 31, 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 effective as of December 31, 2025. Management’s Report on Internal Control Over Financial Reporting Our management is responsible for establishing and maintaining adequate internal control over financial reporting. Our internal control system is designed to provide reasonable assurance to our management and Board of Directors regarding the reliability of financial reporting and the preparation of consolidated financial statements for external purposes. Our management conducted an assessment of the effectiveness of our internal control over financial reporting as of December 31, 2025. This assessment was based on the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission in Internal Control-Integrated Framework (2013 framework). Based on this assessment, management concluded that our internal control over financial reporting was effective as of December 31, 2025. Our independent registered public accounting firm has issued a report on the effectiveness of our internal control over financial reporting, which is below. Changes in Internal Control Over Financial Reporting There were no changes in our internal control over financial reporting identified in connection with the evaluation required by Rules 13a-15(d) and 15d‑15(d) of the Exchange Act that occurred during the quarter ended December 31, 2025 that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting. 93 Table of Contents Report of Independent Registered Public Accounting Firm Board of Directors and Stockholders Lockheed Martin Corporation Opinion on Internal Control over Financial Reporting We have audited Lockheed Martin Corporation’s internal control over financial reporting as of December 31, 2025, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (the COSO criteria). In our opinion, Lockheed Martin Corporation (the Corporation) maintained, in all material respects, effective internal control over financial reporting as of December 31, 2025, based on the COSO criteria. We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheets of the Corporation as of December 31, 2025 and 2024, the related consolidated statements of earnings, comprehensive income, equity and cash flows for each of the three years in the period ended December 31, 2025, and the related notes and our report dated January 29, 2026 expressed an unqualified opinion thereon. Basis for Opinion The Corporation’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management’s Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Corporation’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Corporation in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion. Definition and Limitations of Internal Control Over Financial Reporting A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. /s/ Ernst & Young LLP Tysons, Virginia January 29, 2026 94 Table of Contents ITEM 9B.

The information is provided as of December 31, 2025. Plan category Number of securities to be issued upon exercise of outstanding options, warrants and rights (a) Weighted-average exercise price of outstanding options, warrants and rights (b) Number of securities remaining available for future issuance under equity compensation plans (excluding securities reflected in column (a)) (c) Equity compensation plans approved by security holders (1) 2,744,621 $ — 4,331,863 Equity compensation plans not approved by security holders (2) 351,614 — 2,508,812 Total 3,096,235 $ — 6,840,675 (1) Column (a) includes, as of December 31, 2025: 1,986,297 shares that have been granted as restricted stock units (RSUs) and 707,678 shares that could be earned pursuant to grants of performance stock units (PSUs) (assuming the maximum number of PSUs are earned and payable at the end of the three-year performance period) under the Lockheed Martin Corporation 2020 Incentive Performance Award Plan (2020 IPA Plan) or predecessor plans and 50,646 stock units payable in stock or cash under the Lockheed Martin Corporation Amended and Restated Directors Equity Plan (Directors Plan) or predecessor plans for non-employee directors. Column (c) includes, as of December 31, 2025, 3,974,274 shares available for future issuance under the 2020 IPA Plan as options, stock appreciation rights, restricted stock awards, RSUs or PSUs and 357,589 shares available for future issuance under the Directors Plan as stock options and stock units. Vested stock units are payable to directors upon their termination of service from our Board, except that directors who have satisfied the stock ownership guidelines may elect to have payment of awards made after January 1, 2018 (together with any dividend equivalents thereon) made on the first business day of April following the one-year anniversary of the grant. (2) The shares represent annual incentive bonuses and Long-Term Incentive Performance (LTIP) payments earned and voluntarily deferred by employees. The deferred amounts are payable under the Deferred Management Incentive Compensation Plan (DMICP). Deferred amounts are credited as phantom stock units at the closing price of our stock on the date the deferral is effective. Amounts equal to our dividend are credited as stock units at the time we pay a dividend. Following termination of employment, a number of shares of stock equal to the number of stock units credited to the employee’s DMICP account are distributed to the employee. There is no discount or value transfer on the stock distributed. Distributions may be made from newly issued shares or shares purchased on the open market. Historically, all distributions have come from shares held in a separate trust and, therefore, do not further dilute our common shares outstanding. Because the DMICP shares are outstanding, they should be included in the denominator (and not the numerator) of a dilution calculation. ITEM 13.
