The Base Prospectus (i) as supplemented by the prospectus supplement dated February 2, 2021 specifically relating to the Purchased Notes (as defined below) in the form first filed under Rule 424(b) under the Securities Act (or in the form first made available to the Purchasers (as defined below) by the Company to meet the requests of purchasers pursuant to Rule 173 under the Securities Act) and (ii) all documents filed as part thereof or incorporated or deemed to be incorporated by reference therein are hereinafter collectively called the “Prospectus,” and the preliminary form of the Prospectus is hereinafter called the “Preliminary Prospectus.” For purposes of this Agreement, “free writing prospectus” has the meaning set forth in Rule 405 under the Securities Act and “Time of Sale Prospectus” means the Preliminary Prospectus together with each free writing prospectus, if any, identified in Schedule B hereto. “Time of Sale” means 4:40 p.m. (Eastern Time) on the date of this Agreement. Any reference to “amend,” “amendment” or “supplement” with respect to the Registration Statement, any Preliminary Prospectus or the Prospectus shall be deemed to refer to and include any documents filed after such date under the Securities Exchange Act of 1934, as amended, and the rules and regulations of the Securities and Exchange Commission (the “Commission”) thereunder (collectively, the “Exchange Act”) that are deemed to be incorporated by reference therein.

On the basis of the representations, warranties and agreements contained in this Agreement, but subject to the terms and conditions herein set forth, the purchaser or purchasers named in Schedule A hereto (the “Purchasers”) agree to purchase, severally and not jointly, and the Company agrees to sell to the Purchasers, severally and not jointly, the respective principal amounts of the Company’s 1.167% Senior Notes due 2023 (the “2023 Notes”), 1.433% Senior Notes due 2024 (the “2024 Notes”), and 2.196% Senior Notes due 2026 (the “2026 Notes” and, together with the 2023 Notes and the 2024 Notes, the “Purchased Notes”) set forth opposite the name of each Purchaser on Schedule A hereto. The Purchased Notes will have the terms as set forth in the Pricing Term Sheet on Schedule B hereto.

The price at which the Purchased Notes shall be purchased from the Company by the Purchasers shall be 99.800% of the principal amount of the 2023 Notes, 99.750% of the principal amount of the 2024 Notes, and 99.650% of the principal amount of the 2026 Notes, plus, in each case, accrued interest, if any, from February 4, 2021 to the date of delivery. The initial public offering price shall be 100.000% of the principal amount of the 2023 Notes, 100.000% of the principal amount of the 2024 Notes, and 100.000% of the principal amount of the 2026 Notes, plus, in each case, accrued interest, if any, from February 4, 2021 to the date of delivery. The Purchased Notes will be offered by the Purchasers as set forth in the Time of Sale Prospectus relating to the Purchased Notes.

The Company understands that the Purchasers intend to make a public offering of the Purchased Notes as soon after the effectiveness of this Agreement as in the judgment of the Purchasers is advisable, and initially to offer the Purchased Notes on the terms set forth in the Time of Sale Prospectus. The Company acknowledges and agrees that the Purchasers may offer and sell Purchased Notes to or through any affiliate of a Purchaser and that any such affiliate may offer and sell Purchased Notes purchased by it to or through any Purchaser.

If we are acting as Representatives (as defined on the signature pages hereto) for the several Purchasers named in Schedule A hereto, we represent that we are authorized to act for such several Purchasers in connection with the transactions contemplated in this Agreement, and that, if there are more than one of us, any action under this Agreement taken by any of us will be binding upon all the Purchasers.

All of the provisions contained in the document entitled “The Boeing Company Standard Purchase Provisions,” a copy of which is attached hereto, are hereby incorporated by reference in their entirety and shall be deemed to be a part of this Agreement to the same extent as if such provisions had been set forth in full herein, except that references in Section 10 of “The Boeing Company Standard Purchase Provisions” with respect to this Agreement only, are references to the 2023 Notes, the 2024 Notes, and the 2026 Notes, separately and Section 10 shall apply to each such series separately and not to all such series together.

Each Purchaser that is not a U.S. registered broker-dealer, represents that if it sells Purchased Notes in the United States it will do so through one or more U.S. registered broker-dealers as permitted by the Financial Industry Regulatory Authority regulations.

Each Purchaser hereby agrees that it will not offer, sell or deliver any of the Purchased Notes in any jurisdiction outside the United States except under circumstances that will result in

compliance with the applicable laws thereof, and that it will take at its own expense whatever action is required to permit its resale of the Purchased Notes in such jurisdictions. Each Purchaser understands that no action has been taken to permit a public offering in any jurisdiction outside the United States where action would be required for such purpose. Each Purchaser agrees not to cause any advertisement of the Purchased Notes to be published in any newspaper or periodical or posted in any public place and not to issue any circular relating to the Purchased Notes, except in any such case with the prior express written consent of the Company and the Representatives acting on behalf of the Purchasers, with respect to the 2023 Notes, the Representatives acting on behalf of the Purchasers, with respect to the 2024 Notes, and the Representatives acting on behalf of the Purchasers, with respect to the 2026 Notes, and then only at its own risk and expense.

The Company authorizes the Purchasers to make such public disclosure of information relating to stabilization of the Purchased Notes as is required by applicable law and regulation.

Notwithstanding and to the exclusion of any other term of this Agreement or any other agreements, arrangements, or understanding between the Company and the Underwriters, the Company acknowledges and accepts that a BRRD Liability arising under this Agreement may be subject to the exercise of Bail-in Powers by the Relevant Resolution Authority, and acknowledges, accepts, and agrees to be bound by:

THE BOEING COMPANY

STANDARD PURCHASE PROVISIONS

From time to time, The Boeing Company, a Delaware corporation (“Company”), may enter into purchase agreements that provide for the sale of designated securities to the purchaser or purchasers named therein. The standard provisions set forth herein may be incorporated by reference in any such purchase agreement (“Purchase Agreement”). The Purchase Agreement, including the provisions incorporated therein by reference, is herein sometimes referred to as “this Agreement.” Unless otherwise defined herein, terms defined in the Purchase Agreement are used herein as therein defined.

1. Introductory. The Company proposes to issue and sell from time to time its Unsecured Debt Securities (“Notes”) registered under the registration statement referred to in Section 2(a). The Notes will be issued under an Indenture, dated as of February 1, 2003, between the Company and The Bank of New York Mellon Trust Company, N.A., as successor to JPMorgan Chase Bank, as Trustee, as may be supplemented from time to time, (the “Indenture”). The Notes will be sold to the Purchasers (as defined below) for resale in accordance with the terms of the offering determined at the time of the sale. The Notes involved in any such offering are hereinafter referred to as the “Purchased Notes,” and the firm or firms, as the case may be, which agree to purchase the same are hereinafter referred to as the “Purchasers” of such Purchased Notes. The terms “you” and “your” refer to those Purchasers who sign the Purchase Agreement either on behalf of themselves only or on behalf of themselves and as representatives of the several Purchasers named in Schedule A thereto, as the case may be.

2. Representations and Warranties of the Company. The Company represents and warrants to and agrees with each Purchaser that:

(a) A Registration Statement (as defined in the Purchase Agreement) covering an indeterminate amount of the securities of the Company (including the Purchased Notes), including a prospectus has been filed with the Securities and Exchange Commission (“Commission”) and has become effective under the Securities Act of 1933, as amended (the “Securities Act”); no stop order suspending the effectiveness of the Registration Statement is in effect, and no proceedings for such purpose are pending before or threatened by the Commission. The Company is a well known seasoned issuer (as defined in Rule 405 under the Securities Act) eligible to use the Registration Statement as an automatic shelf registration statement and the Company has not received notice that the Commission objects to the use of the Registration Statement as an automatic shelf registration statement. The terms Registration Statement, Time of Sale Prospectus and Prospectus shall have the meanings ascribed to them in the Purchase Agreement.

(b) The Company is not an “ineligible issuer” in connection with the offering pursuant to Rules 164, 405 and 433 under the Securities Act. Any free writing prospectus that the Company is required to file pursuant to Rule 433(d) under the Securities Act has been, or will be, filed with the Commission in accordance with the requirements of the Securities Act and the applicable rules and regulations of the Commission thereunder (the “Securities Act Rules and Regulations”). Each free writing prospectus that the Company has filed, or is required to file, pursuant to Rule 433(d) under the Securities Act or that was prepared by or on behalf of or used or referred to by the Company complies or will comply in all material respects with the requirements of the Securities Act and the applicable rules and regulations of the Commission thereunder. Except for the free writing prospectuses, if any, identified in Schedule B to the Purchase Agreement, the Company has not prepared, used or referred to, and will not, without your prior consent, prepare, use or refer to, any free writing prospectus. Each free writing prospectus that the Company has filed, as of its issue

date and at all subsequent times through the completion of the public offer and sale of the Purchased Notes or until any earlier date that the Company notifies the Purchasers as described in the next sentence, will not contain any information that conflicts with the information contained in the Registration Statement, including any document incorporated by reference therein, the Time of Sale Prospectus, the Prospectus and any prospectus supplement deemed to be a part thereof that has not been superseded or modified. If at any time following issuance of a free writing prospectus that the Company has filed there occurs an event or development as a result of which such free writing prospectus contained an untrue statement of a material fact or omits to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, the Company will promptly notify the Purchasers so that any use of such free writing prospectus may cease until it is amended or supplemented. The foregoing two sentences do not apply to statements or omissions in such document based upon written information furnished to the Company by any Purchaser specifically for use therein.

(c) The Registration Statement conforms in all respects to the requirements of the Securities Act and the Securities Act Rules and Regulations and does not include any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading, except that the foregoing does not apply to statements or omissions in such document based upon written information furnished to the Company by any Purchaser specifically for use therein. At the Time of Sale, the Time of Sale Prospectus did not contain any untrue statement of a material fact or omit to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, except that the foregoing does not apply to statements or omissions in such document based upon written information furnished to the Company by any Purchaser specifically for use therein. The Prospectus, as of its date, does not contain and, as amended or supplemented, if applicable, and as of the Closing Date, will not contain any untrue statement of a material fact or omit to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, except that the foregoing does not apply to statements or omissions in such document based upon written information furnished to the Company by any Purchaser specifically for use therein.

This indemnity agreement will be in addition to any liability which such Purchaser may otherwise have.

(c) Promptly after receipt by an indemnified party under this Section of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under (a) and (b) above, notify the indemnifying

party of the commencement thereof; but the omission so to notify the indemnifying party will not relieve it from any liability which it may have to any indemnified party otherwise than under this Section, except to the extent the indemnifying party has been materially prejudiced by such omission. In case any such action is brought against any indemnified party, and it notifies the indemnifying party of the commencement thereof, the indemnifying party will be entitled to participate therein and, to the extent that it may wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel satisfactory to such indemnified party (who may, with the consent of the indemnified party, be counsel to the indemnifying party) and who shall not be counsel to any other indemnified party who may have interests conflicting with those of such indemnified party, and after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party will not be liable to such indemnified party under this Section for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof other than reasonable costs of investigation. The indemnifying party shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the indemnifying party agrees to indemnify each indemnified party from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested that an indemnifying party reimburse the indemnified party for fees and expenses of counsel as contemplated by this paragraph, the indemnifying party shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 30 days after receipt by the indemnifying party of such request and (ii) the indemnifying party shall not have reimbursed the indemnified party in accordance with such request prior to the date of such settlement unless the request is being disputed in good faith. No indemnifying party shall, without the written consent of the indemnified party, effect any settlement of any pending or threatened proceeding in respect of which any indemnified party is or could have been a party and indemnification could have been sought hereunder by such indemnified party, unless such settlement (x) includes an unconditional release of such indemnified party, in form and substance reasonably satisfactory to such indemnified party, from all liability on claims that are the subject matter of such proceeding and (y) does not include any statement as to or any admission of fault, culpability or a failure to act by or on behalf of any indemnified party.

(d) If recovery is not available under the foregoing indemnification provisions of this Section, for any reason other than as specified therein, the parties entitled to indemnification by the terms thereof shall be entitled to contribution to liabilities and expenses, except to the extent that contribution is not permitted under Section 11(f) of the Act. In determining the amount of contribution to which the respective parties are entitled, there shall be considered the relative benefits received by each party from the offering of the Purchased Notes (taking into account the portion of the proceeds of the offering realized by each), the parties’ relative knowledge and access to information concerning the matter with respect to which the claim was asserted, the opportunity to correct and prevent any statement or omission, and any other equitable considerations appropriate under the circumstances. The relative benefits received by the Company on the one hand and the Purchasers on the other shall be deemed to be in the same respective proportions as the net proceeds (before deducting expenses) received by the Company from the sale of the Purchased Notes and the total underwriting discounts and commissions received by the Purchasers in connection therewith, in each case as set forth in the table on the cover of the Prospectus, bear to the aggregate offering price of the Purchased Notes. The Company and the Purchasers and such controlling persons agree that it would not be equitable if the amount of such contribution were determined by pro rata or per capita allocation (even if the Purchasers and such controlling persons were treated as one entity for such purpose). Notwithstanding the provisions of this subsection (d), no Purchaser or controlling person shall be required to

make contribution hereunder which in the aggregate exceeds the total public offering price of the Purchased Notes, purchased by the Purchaser under this Agreement, less the aggregate amount of any damages which such Purchaser or such controlling person has otherwise been required to pay in respect of the same claim or any substantially similar claim. The Purchasers’ obligations to contribute are several in proportion to their respective underwriting obligations and not joint.

10. Default of Purchasers. If any Purchaser or Purchasers default in their obligations to purchase Purchased Notes hereunder and the aggregate principal amount of Purchased Notes which such defaulting Purchaser or Purchasers agreed but failed to purchase is 10% of the principal amount of Purchased Notes or less, the non-defaulting Purchasers may make arrangements satisfactory to the Company for the purchase of such Purchased Notes by other persons, including any of the Purchasers, but if no such arrangements are made by the Closing Date the non-defaulting Purchasers shall be obligated severally, in proportion to their respective commitments hereunder, to purchase the Purchased Notes which such defaulting Purchasers agreed but failed to purchase. If any Purchaser or Purchasers so default and the aggregate principal amount of Purchased Notes with respect to which such default or defaults occur is more than the above percentage and arrangements reasonably satisfactory to you and the Company for the purchase of such Purchased Notes by other persons are not made within seventy-two hours after such default, this Agreement will terminate without liability on the part of any non-defaulting Purchaser or the Company, except as provided in Section 11. In the event that any Purchaser or Purchasers default in their obligation to purchase Purchased Notes hereunder, the Company may, by prompt written notice to the non-defaulting Purchasers, postpone the Closing Date for a period of not more than seven full business days in order to effect whatever changes may thereby be made necessary in the Registration Statement or the Prospectus or in any other documents, and the Company will promptly file any amendments to the Registration Statement or supplements to the Time of Sale Prospectus or the Prospectus which may thereby be made necessary. As used in this Agreement, the term “Purchaser” includes any person substituted for a Purchaser under this Section. Nothing herein will relieve a defaulting Purchaser from liability for its default.

11. Termination. This Agreement may be terminated, by notice to the Company, if after the execution and delivery of this Agreement and prior to the Closing Date (i) trading generally shall have been suspended or materially limited on the New York Stock Exchange; (ii) trading of any securities issued or guaranteed by the Company shall have been suspended on any exchange; (iii) a general moratorium on commercial banking activities shall have been declared by federal or New York State authorities or a material disruption in commercial banking or securities settlement clearance services in the United States; or (iv) there shall have occurred any outbreak or escalation of hostilities or any change in financial markets or any calamity or crisis, either within or outside the United States, that, in each case in the reasonable judgment of the Purchasers, is material and adverse and makes it impracticable or inadvisable to proceed with the offering, sale or delivery of the Purchased Notes on the terms and in the manner contemplated by this Agreement, the Time of Sale Prospectus and the Prospectus.

12. Survival of Certain Representations and Obligations. The respective indemnities, agreements, representations, warranties, and other statements of the Company or its officers and of the several Purchasers set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation, or statement as to the results thereof, made by or on behalf of any Purchaser or the Company or any of its officers or directors or any controlling person, and will survive delivery of and payment for the Purchased Notes. If this Agreement is terminated pursuant to Section 7, 8, 10 or 11 or if for any reason the purchase of the Purchased Notes by the Purchasers is not consummated, the Company shall remain responsible for the expenses to be paid or reimbursed by it pursuant to Section 5(h). In addition, in such event the respective obligations of the Company and the Purchasers pursuant to Section 9 shall remain in effect; provided, however, that each Purchaser will use its best efforts to promptly notify each

other Purchaser and each dealer and prospective customer to whom such Purchaser has delivered a Prospectus for the Purchased Notes by telephone or telegraph, confirmed by letter in either case, of such termination or failure to consummate, including in such notice instructions regarding the continued use of the Registration Statement, the Time of Sale Prospectus, the Prospectus, or any amendment or supplement thereto.

13. Notices. All communications hereunder will be in writing, and, if sent to the Purchasers will be delivered or telecopied and confirmed to the address furnished in writing for the purpose of such communications hereunder, or, if sent to the Company, will be delivered or telecopied and confirmed to it, attention of Treasurer at 100 North Riverside, Chicago, Illinois 60606, telecopier (312) 544-2399, with a copy to Corporate Secretary at the same address, telecopier (312) 544-2829.

14. Successors. This Purchase Agreement will inure to the benefit of and be binding upon the parties hereto and their respective successors and the officers and directors and controlling persons referred to in Section 9, and no other person will have any right or obligation hereunder.

15. WAIVER OF JURY TRIAL. EACH OF THE COMPANY AND THE PURCHASERS HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS PURCHASE AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY.

16. Entire Agreement. This Agreement, together with any contemporaneous written agreements and any prior written agreements (to the extent not superseded by this Agreement) that relate to the offering of the Purchased Notes, represents the entire agreement between the Company and the Purchasers with respect to the preparation of the Time of Sale Prospectus and the Prospectus, the conduct of the offering, and the purchase and sale of the Purchased Notes.

(b) The Company acknowledges that in connection with the offering of the Purchased Notes: (i) the Purchasers have acted at arm’s-length, are not agents of, and owe no fiduciary duties to, the Company or any other person, (ii) the Purchasers owe the Company only those duties and obligations set forth in this Agreement and prior written agreements to the extent not superseded by this Agreement), if any, and (iii) the Purchasers may have interests that differ from those of the Company. The Company waives to the full extent permitted by applicable law any claims it may have against the Purchasers arising from an alleged breach of fiduciary duty in connection with the offering of the Purchased Notes.

17. Construction. This Purchase Agreement shall be governed by and construed in accordance with the laws of the State of New York without giving effect to any conflicts of law provisions that would apply the laws of another jurisdiction.

18. Counterparts. This Agreement may be executed in one or more counterparts and it is not necessary that the signatures of all parties appear on the same counterpart, but such counterparts together shall constitute but one and the same agreement.

19. Amendments or Waivers. No amendment or waiver of any provision of this Agreement, nor any consent or approval to any departure therefrom, shall in any event be effective unless the same shall be in writing and signed by the parties hereto.

EXHIBIT A

1. Based solely on our review of the Delaware Certificate, the Company has been duly incorporated and is validly existing and in good standing under the General Corporation Law of the State of Delaware.

2. The Indenture has been duly authorized, executed and delivered by the Company and is a valid instrument, legally binding on the Company and enforceable in accordance with its terms.

3. The issuance and sale of the Purchased Notes have been duly authorized by all necessary corporate action of the Company. The Purchased Notes (assuming that they have been duly authenticated by the Trustee or a duly designated Authentication Agent under the Indenture, which fact we have not verified by an inspection of the Purchased Notes) have been duly issued and constitute legal, valid and binding obligations of the Company enforceable in accordance with their terms, and are entitled to the benefits provided by the Indenture.

4. To our knowledge, the Company is not required to obtain any consent, approval, authorization or order of any governmental agency for the execution, delivery and performance by the Company of the Purchase Agreement, the Indenture and the Purchased Notes, the issuance and sale of the Purchased Notes being issued and sold by the Company under the Purchase Agreement and the Indenture, except for the registration of the Purchased Notes under the Securities Act, the qualification of the Indenture under the Trust Indenture Act of 1939, as amended (the “Trust Indenture Act”), and such consents, approvals, authorizations or orders as may be required under applicable state securities laws in connection with the purchase and distribution of the Purchased Notes by the Purchasers.

5. The Registration Statement (as of its effective date) and the Prospectus (as of the date of the Purchase Agreement and as of the Closing Date), appeared on their faces to have complied as to form in all material aspects to the requirements of the Securities Act and the rules and regulations promulgated thereunder, except that, in each case, we do not express any opinion as to any financial statements or supporting schedules (or any notes to any such statements or schedules) or other financial information, in each case, in (or omitted from) the Registration Statement or the Prospectus.

6. The performance by the Company of its obligations under the Purchase Agreement and the performance by the Company of its obligations under the Indenture will not result in a breach of any of the terms and provisions of, the Company’s Charter or By-Laws, any provision of any Specified Contract (provided that we express no opinion as to compliance with any financial test or cross-default provision in such Specified Contract) or result in a violation of the Specified Laws.

7. The Purchase Agreement has been duly authorized, executed and delivered by the Company.

8. The statements set forth in the Time of Sale Prospectus and the Prospectus under the caption “Description of Notes,” and under the caption “Description of Debt Securities” of the Time of Sale Prospectus and the Prospectus insofar as they purport to constitute a summary of the terms of the Indenture and the Purchased Notes, are correct in all material respects. The statements in the Time of Sale Prospectus and the Prospectus under the caption “Material United States Federal Income Tax Considerations,” insofar as such statements constitute summaries of legal matters referred to therein, correctly summarize in all material respects the legal matters referred to therein.

9. To our knowledge, there are no legal or governmental proceedings that are pending against the Company or any of its subsidiaries or to which any property of the Company or any of its subsidiaries is subject that has caused us to conclude that such proceeding is required by Item 103 of Regulation S-K promulgated under the Securities Act to be described in the Registration Statement, the Time of Sale Prospectus or the Prospectus but is not so described.

10. The Company is not and, after giving effect to the offering and sale of the Purchased Notes and the application of the proceeds thereof as described in the Registration Statement, the Time of Sale Prospectus and the Prospectus, will not be an “investment company” required to register as such under the Investment Company Act of 1940, as amended, and the rules and regulations thereunder.

11. The Company’s Annual Report on Form 10-K for the most recently ended fiscal year as filed with the Commission complied as to form in all material respects with the requirements of the Securities Exchange Act of 1934, as amended, and the rules and regulations of the Commission thereunder, except that we do not express any opinion as to any financial statements or supporting schedules (or any notes to any such statements or schedules) or other financial information therein (or omitted therefrom).

12. The Indenture has been duly qualified under the Trust Indenture Act.
