Table of Contents REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM To the Plan Participants and Plan Administrator of The Boeing Company Voluntary Investment Plan Chicago, Illinois Opinion on the Financial Statements We have audited the accompanying statements of net assets available for benefits of The Boeing Company Voluntary Investment Plan (the "Plan") as of December 31, 2020 and 2019, the related statement of changes in net assets available for benefits for the year ended December 31, 2020, and the related notes (collectively referred to as the "financial statements"). In our opinion, the financial statements present fairly, in all material respects, the net assets available for benefits of the Plan as of December 31, 2020 and 2019, and the changes in net assets available for benefits for the year ended December 31, 2020, in conformity with accounting principles generally accepted in the United States of America. Basis for Opinion These financial statements are the responsibility of the Plan's management. Our responsibility is to express an opinion on the Plan's financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Plan 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 audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion. Report on Supplemental Schedule The supplemental schedule listed in the table of contents has been subjected to audit procedures performed in conjunction with the audit of the financial statements. The supplemental schedule is the responsibility of the Plan’s management. Our audit procedures included determining whether the supplemental schedule reconciles to the 2020 financial statements or the underlying accounting and other records, as applicable, and performing procedures to test the completeness and accuracy of the information presented in the supplemental schedule. In forming our opinion on the supplemental schedule, we evaluated whether the supplemental schedule, including the form and content, is presented in compliance with the Department of Labor's Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974. In our opinion, such supplemental schedule is fairly stated, in all material respects, in relation to the financial statements as a whole. /s/ Deloitte & Touche LLP Chicago, Illinois June 15, 2021 We have served as the auditor of the Plan since at least 1990; however, an earlier year could not be reliably determined. 1 Table of Contents THE BOEING COMPANY VOLUNTARY INVESTMENT PLAN STATEMENTS OF NET ASSETS AVAILABLE FOR BENEFITS AS OF DECEMBER 31, 2020 AND 2019 (Dollars in millions) 2020 2019 ASSETS: Investments — interest in Master Trust $ 68,113 $ 66,426 Receivables: Participant contributions 10 — Notes receivable from participants 681 746 Total receivables 691 746 NET ASSETS AVAILABLE FOR BENEFITS $ 68,804 $ 67,172 See notes to financial statements. 2 Table of Contents THE BOEING COMPANY VOLUNTARY INVESTMENT PLAN STATEMENT OF CHANGES IN NET ASSETS AVAILABLE FOR BENEFITS FOR THE YEAR ENDED DECEMBER 31, 2020 (Dollars in millions) ADDITIONS: Net Master Trust activity $ 3,092 Interest income from notes receivable from participants 30 Contributions: Employer — cash 1,130 Employer — Boeing common stock 194 Participant 2,249 Total contributions 3,573 Total additions 6,695 DEDUCTIONS — Benefits paid 5,225 NET ADDITIONS BEFORE ASSETS TRANSFER 1,470 ASSETS TRANSFERRED FROM ANOTHER PLAN 162 NET ASSETS AVAILABLE FOR BENEFITS: Beginning of year 67,172 End of year $ 68,804 See notes to financial statements. 3 Table of Contents THE BOEING COMPANY VOLUNTARY INVESTMENT PLAN NOTES TO FINANCIAL STATEMENTS AS OF DECEMBER 31, 2020 AND 2019 AND FOR THE YEAR ENDED DECEMBER 31, 2020 (Dollars in millions) 1. DESCRIPTION OF PLAN The following description of The Boeing Company Voluntary Investment Plan (the “VIP” or the “Plan”) provides only general information. Participants, as defined by the Plan, (“Members”) should refer to the plan document for a more complete description of the Plan’s provisions. General — The Plan is a defined contribution plan intended to qualify under the Internal Revenue Code (“IRC”) as a profit sharing plan with a cash or deferred arrangement and employee stock ownership plan component, and is designed to provide Members with a means of making regular savings for their retirement. An eligible employee of The Boeing Company (the “Company” or “Boeing”) or one of its adopting subsidiaries becomes eligible to participate on the first day of employment. The Plan includes an auto-enrollment provision for newly-eligible employees unless they affirmatively elect not to participate in the Plan. Automatically enrolled Members have their deferral rate set at a percentage of eligible compensation as defined in the plan document and their contributions are invested in a qualified default investment alternative (“QDIA”) until changed by the Members. The current QDIA for the Plan is the applicable custom target date fund. The assets of the Plan, excluding notes receivable from participants, are held in The Boeing Company Employee Savings Plans Master Trust (the “Master Trust”). The Northern Trust Company (“NT”) serves as trustee for the Master Trust. The Employee Benefit Plans Committee oversees the operation and administration of the Plan. The Plan is subject to the provisions of the Employee Retirement Income Security Act of 1974 (“ERISA”), as amended. Contributions — Members may elect to contribute to the Plan a percentage of their eligible compensation on a pretax, after-tax, Roth, or a combination of those contribution types, as defined in the plan document and subject to statutory limitations. Members who have attained age 50 before the end of the plan year are eligible to make catch-up contributions, as defined in the plan document and subject to statutory limits. Catch-up contributions are ineligible for an employer-matching contribution. The Plan also accepts certain rollover contributions. Under the terms of the Plan, Boeing makes employer-matching and Company contributions for eligible Members. Members should refer to the plan document for details. Effective November 5, 2020, employer contributions are generally made in the form of shares of Company common stock and immediately transferred to other investment funds in accordance with Members’ current investment elections. Members may elect to change their contribution percentages. These changes are effective the next pay period after the request is received, or as soon as administratively possible thereafter. The allocation of both Members’ contributions and employer contributions to the funds may be changed at any time and become effective on the day of the change or the next business day, according to the time of the request for a change in relation to the stock market close of business. Members’ Accounts — Individual accounts are maintained for each Member. Each Member’s account is credited with the Member’s contributions, employer-matching contributions, Company contributions,
