The Boeing Company, a Delaware corporation (“Company”), proposes to issue and sell to the several purchasers listed in Schedule A hereto (the “Purchasers”), for whom you are acting as representatives (the “Representatives”), an aggregate of 112,500,000 shares of its common stock, par value $5.00 per share (“Common Stock”) (such shares of Common Stock, the “Firm Shares”) and, at the option of the Purchasers, up to 16,875,000 additional shares of its Common Stock (such additional shares of Common Stock, the “Option Shares”). In this underwriting agreement (this “Agreement”), the Firm Shares and the Option Shares that the Purchasers elect to purchase pursuant to Section 2 hereof are collectively referred to as the “Shares.”

Substantially concurrently with the offering of the Shares contemplated hereby, the Company will, among other things, issue and sell up to 115,000,000 depositary shares (the “Depositary Shares”), each representing a 1/20th interest in a share of 6.00% Series A Mandatory Convertible Preferred Stock, par value $1.00 per share (the “Preferred Stock”), pursuant to a separate underwriting agreement and separate prospectus supplement, subject to customary closing conditions (the “Concurrent Offering”). The offering of the Shares is not contingent upon the completion of the Concurrent Offering, the Concurrent Offering is not contingent upon the completion of the offering of the Shares, and the Shares are not being offered together with the Depositary Shares.

The Company hereby confirms its agreement with the several Purchasers concerning the purchase and sale of the Shares, as follows:

1. Registration Statement. A registration statement on Form S-3 (File No. 333-282628), including a prospectus, covering the Shares has been filed with the Securities and Exchange Commission (“Commission”) under the Securities Act of 1933, as amended, and the rules and regulations of the Commission thereunder (collectively, the “Securities Act”). Such registration statement, including the prospectus included therein (the “Base Prospectus”), and all documents filed as part thereof or incorporated by reference therein including the information, if any, deemed pursuant to Rule 430A, 430B or 430C under the Securities Act to be part of the registration statement at the time of its effectiveness, and at each deemed effective date with respect to the Purchasers pursuant to Rule

430B(f)(2) of the Securities Act, are hereinafter collectively called the “Registration Statement.” The Base Prospectus, as supplemented by the prospectus supplement dated October 28, 2024 specifically relating to the Shares in the form first filed under Rule 424(b) under the Securities Act (or in the form first made available to the Purchasers by the Company to meet the requests of purchasers pursuant to Rule 173 under the Securities Act), and 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.” If the Company has filed an abbreviated registration statement pursuant to Rule 462(b) under the Securities Act (the “Rule 462 Registration Statement”), then any reference herein to the term “Registration Statement” shall be deemed to include such Rule 462 Registration Statement. 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 9:00 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 Commission thereunder (collectively, the “Exchange Act”) that are deemed to be incorporated by reference therein.

2. Purchase of the Shares. On the basis of the representations, warranties and agreements contained in this Agreement, but subject to the terms and conditions herein set forth, the Company agrees to issue and sell the Firm Shares to the several Purchasers, and each Purchaser agrees, severally and not jointly, to purchase from the Company the respective number of Firm Shares set forth opposite such Purchaser’s name in Schedule A hereto at a price per share of $140.67625 (the “Purchase Price”). In addition, on the basis of the representations, warranties and agreements contained in this Agreement, but subject to the terms and conditions herein set forth, the Company agrees to issue and sell the Option Shares to the several Purchasers as provided in this Agreement, and the Purchasers shall have the option to purchase, severally and not jointly, from the Company the Option Shares at the Purchase Price less an amount per share equal to any dividends or distributions declared by the Company and payable on the Firm Shares but not payable on the Option Shares. If any Option Shares are to be purchased, the number of Option Shares to be purchased by each Purchaser shall be the number of Option Shares which bears the same ratio to the aggregate number of Option Shares being purchased as the number of Firm Shares set forth opposite the name of such Purchaser in Schedule A hereto (or such number increased as set forth in Section 12 hereof) bears to the aggregate number of Firm Shares being purchased from the Company by the several Purchasers, subject, however, to such adjustments to eliminate any fractional Shares as you, in your sole discretion, shall make. The Purchasers may exercise the option to purchase Option Shares at any time in whole, or from time to time in part, on or before the thirtieth day following the date of the Prospectus, by written notice from the Representatives to the Company. Such notice shall set forth the aggregate number of Option Shares as to which the option is being exercised and the date and time when the Option Shares are to be delivered and paid for, which may be the same date and time as the Closing Date (as defined below) but shall not be earlier than the Closing Date nor later than the tenth full business day after the date of such notice (unless such time and date are postponed in accordance with the provisions of Section 12 hereof). Any such notice shall be given at least two business days prior to the date and time of delivery specified therein, except to the extent that the date on which the Option Shares are to be delivered is the same date and time as the Closing Date, in which case such notice may be delivered one business day prior to the date and time of delivery specified therein.

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

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

(a) The Registration Statement has become effective under 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.

(b) 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. 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. Except for the free writing prospectuses, if any, identified in Schedule B to this 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 Shares 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, it being understood and agreed that the only such information furnished by any Purchaser consists of the information described as such in Section 11(b) hereof.

(c) The Registration Statement complies in all material respects to the requirements of the Securities Act 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, it being understood and agreed that the only such information furnished by any Purchaser consists of the information described as such in Section 11(b) hereof. 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, it being understood and agreed that the only such information furnished by any Purchaser consists of the information described as such in Section 11(b) hereof. The Prospectus, as of its date, complies in all material respects with the requirements of the Securities Act and does not contain and, as amended or supplemented, if applicable, and as of the Closing Date and as of the Additional Closing Date (as defined below), as the case may be, will comply in all material respects with the requirements of the Securities Act and 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, it being understood and agreed that the only such information furnished by any Purchaser consists of the information described as such in Section 11(b) hereof. The documents incorporated by reference in the Registration Statement, the Time of Sale Prospectus or the Prospectus pursuant to Item 12 of Form S-3 of the Securities Act, at the time they were filed with the Commission, complied in all material respects with the requirements of the Exchange Act. Any additional documents deemed to be incorporated by reference in the Time of Sale Prospectus or the Prospectus, will, when they are filed with the Commission, comply in all material respects with the requirements of the Exchange Act and will not contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading.

(d) The Company (i) has not alone engaged in any Testing-the-Waters Communications other than Testing-the-Waters Communications with the consent of Goldman Sachs & Co. LLC with entities that the Company reasonably believed to be qualified institutional buyers (“QIBs”) within the meaning of Rule 144A under the Securities Act or institutions that are accredited investors within the meaning of Rule 501(a)(1), (a)(2), (a)(3), (a)(7), (a)(8), (a)(9), (a)(12) or (a)(13) under the Securities Act (“IAIs”) and otherwise in compliance with the requirements of Rule 163B under the Securities Act and (ii) has not authorized anyone other than the Representatives to engage in Testing-the-Waters Communications. The Company reconfirms that the Representatives have been authorized to act on its behalf in undertaking Testing-the-Waters Communications. The Company has not distributed or approved for distribution any Written Testing-the-Waters Communications other than those listed on Schedule D hereto. “Written Testing-the-Waters Communication” means any Testing-the-Waters Communication that is a written communication within the meaning of Rule 405 under the Securities Act. Any individual Written Testing-the-Waters Communication does not conflict with the information contained in the Registration Statement or the Time of Sale Prospectus, complied in all material respects with the requirements of the Securities Act, and when taken together with the Time of Sale Prospectus as of the Time of Sale did not, and as of the Closing Date and as of the Additional Closing Date, as the case may be, will not, contain any untrue statement of a material fact or omit 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. If at any time following the use of a Written Testing-the-Waters Communication, there occurs an event or development as a result of which such Written Testing-the-Waters Communication 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 Written Testing-the-Waters Communication 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, it being understood and agreed that the only such information furnished by any Purchaser consists of the information described as such in Section 11(b) hereof.

(f) The Company will furnish to you copies of the following documents, in each case as soon as available after filing and in such quantities as you reasonably request: (i) the registration statement relating to the Shares as originally filed and all post-effective amendments thereto (at least one of which will be signed and will include all exhibits except those incorporated by reference to previous filings with the Commission); (ii) each prospectus relating to the Shares; and (iii) during the time when a prospectus relating to the Shares is required to be delivered under the Securities Act, all post-effective amendments and supplements to the Registration Statement, the Time of Sale Prospectus or the Prospectus, respectively (except supplements relating to securities that are not the Shares).

If this Agreement is terminated by the Purchasers in accordance with the provisions of Section 9, the Company shall reimburse the Purchasers for all of their reasonable out-of-pocket expenses, including the reasonable fees and disbursements of counsel for the Purchasers.

(i) For a period of 90 days after the date of the Prospectus, the Company will not (i) offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, lend, or otherwise transfer or dispose of, directly or indirectly, or submit to, or file with, the Commission a registration statement under the Securities Act relating to, any shares of Common Stock or any securities convertible into or exercisable or exchangeable for Common Stock, or publicly disclose the intention to undertake any of the foregoing, or (ii) enter into any swap or other agreement that transfers, in whole or in part, any of the economic consequences of ownership of the Common Stock or any such other securities, whether any such transaction described in clause (i) or (ii) above is to be settled by delivery of Common Stock or such other securities, in cash or otherwise, without the prior written consent of Goldman Sachs & Co. LLC, other than the Shares to be sold hereunder. The restrictions described above do not apply to (i) the issuance of shares of Common Stock or securities convertible into or exercisable for shares of Common Stock pursuant to the conversion or exchange of convertible or exchangeable securities or the exercise of warrants or options (including net exercise) or the settlement of RSUs (including net settlement), in each case, outstanding on the date of this Agreement, (ii) grants of stock options, stock awards, restricted stock, RSUs, or other equity awards and the issuance of shares of Common Stock or securities convertible into or exercisable or exchangeable for shares of Common Stock (whether upon the exercise of stock options or otherwise) to the Company’s employees, officers, directors, advisors, or consultants pursuant to the terms of an equity compensation plan in effect as of the Closing Date; (iii) contributions of shares of Common Stock to the Company’s 401(k) plan in effect as of the Closing Date; (iv) issuance of shares of Common Stock pursuant to the terms of the Company’s qualified and nonqualified retirement plans in effect as of the Closing Date; (v) the issuance of up to 5% of the outstanding shares of Common Stock, or securities convertible into, exercisable for, or which are otherwise exchangeable for, Common Stock, immediately following the Closing Date, in acquisitions or other similar strategic transactions, (vi) the filing of any registration statement on Form S-8 relating to securities granted or to be granted pursuant to any plan in effect on the date of this Agreement or any assumed benefit plan pursuant to an acquisition or similar strategic transaction, (vii) the issuance of shares of Common Stock pursuant to the Agreement and Plan of Merger, dated June 30, 2024, among the Company, Spirit AeroSystems Holdings, Inc. and Sphere Acquisition Corp., and the filing of any registration statement on Form S-4 or any amendment or supplement thereto relating to such shares of Common Stock, and (viii) the Depositary Shares that may be issued pursuant to the Concurrent Offering and the Preferred Stock in respect thereof, and any shares of Common Stock issued upon conversion of, or issued and paid as a dividend on, such Preferred Stock.

(j) The Company will prepare a final term sheet relating to the offering of the Shares and the Concurrent Offering, containing only information that describes the final terms of the offering of the Shares and the Concurrent Offering in a form consented to by the Purchasers, and to file such final term sheet within the period required by Rule 433(d)(5)(ii) under the Securities Act following the date the final terms have been established for the offering of the Shares and the Concurrent Offering.

(k) The Company will advise the Purchasers promptly, and confirm such advice in writing, (i) when any amendment to the Registration Statement has been filed or becomes effective prior to the Closing Date or the Additional Closing Date, as the case may be; (ii) when any supplement to the Prospectus or any amendment to the Prospectus or any free writing prospectus has been filed prior to the Closing Date or the Additional Closing Date, as the case may be; (iii) of any request by the Commission for any amendment to the Registration Statement or any amendment or supplement to the Prospectus or the receipt of any comments from the Commission relating to the Registration Statement or any other request by the Commission for any additional information relating to the offering of the Shares prior to the Closing Date or the Additional Closing Date, as the case may be; (iv) of the issuance by the Commission of any order suspending the effectiveness of the Registration Statement or preventing or suspending the use of any Preliminary Prospectus or the Prospectus or the initiation or threatening of any proceeding for that purpose or pursuant to Section 8A of the Securities Act; (v) of the occurrence of any event during the period that a prospectus is required to be delivered as a result of which the Prospectus, the Time of Sale Prospectus or any free writing prospectus as then amended or supplemented would include any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances existing when the Prospectus, the Time of Sale Prospectus or any such free writing prospectus is delivered to a purchaser, not misleading; and (vi) of the receipt by the Company of any notice with respect to any suspension of the qualification of the Shares for offer and sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose; and the Company will use its reasonable best efforts to prevent the issuance of any such order suspending the effectiveness of the Registration Statement, preventing or suspending the use of any Preliminary Prospectus or the Prospectus or suspending any such qualification of the Shares and, if any such order is issued, will use its reasonable best efforts to obtain as soon as possible the withdrawal thereof.

(l) The Company will qualify the Shares for offering and sale under the applicable securities laws of such states and other jurisdictions as you may reasonably designate in consultation with the Company and maintain such qualifications in effect for a period of not less than a year from the date of the Prospectus; provided, however, that the Company shall not be obligated to file any general consent to service of process or to qualify as a foreign corporation or as a dealer in securities in any jurisdiction in which it is not so qualified or to subject itself to taxation in respect of doing business in any jurisdiction in which it is not otherwise so subject. The Company will file such statements and reports as may be required by the laws of each jurisdiction in which the Shares have been qualified as above provided. The Company will also supply you with such information as is necessary for the determination of the legality of the Shares for investment under the laws of such jurisdictions as you may request.

(m) The Company will use its reasonable best efforts in cooperation with you to permit the Shares offered and sold in transactions by you to be eligible for clearance and settlement through DTC.

(n) The Company will apply the net proceeds received by it from the sale of the Shares in the manner specified in the Time of Sale Prospectus and the Prospectus under the heading “Use of Proceeds.”

(o) The Company will use its reasonable best efforts to list, subject to notice of issuance, the Shares on the New York Stock Exchange.

(p) The Company authorizes the Purchasers to make such public disclosure of information relating to stabilization of the Shares as is required by applicable law and regulation.

8. Covenants of the Purchasers.

(a) Each Purchaser severally covenants with the Company not to take any action that would result in the Company being required to file with the Commission under Rule 433(d) a free writing prospectus prepared by or on behalf of such Purchaser that otherwise would not be required to be filed by the Company thereunder, but the for the action of the Purchaser.

(b) Each Purchaser that is not a U.S. registered broker-dealer, represents that if it sells Shares 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.

(c) Each Purchaser hereby agrees that it will not offer, sell or deliver any of the Shares 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 Shares 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 Shares to be published in any newspaper or periodical or posted in any public place and not to issue any circular relating to the Shares, except in any such case with the prior express written consent of the Company and the Representatives acting on behalf of the Purchasers.

9. Conditions of the Obligations of the Purchasers. The obligations of the several Purchasers to purchase and pay for the Firm Shares on the Closing Date or the Option Shares on the Additional Closing Date will be subject to the accuracy of the representations and warranties on the part of the Company herein, to the accuracy of the statements of Company officers made pursuant to the provisions hereof, to the performance by the Company of its obligations hereunder and to the following additional conditions precedent:

(a) On the date of execution of this Agreement and on the Closing Date or the Additional Closing Date, as the case may be, you shall have received from Deloitte & Touche LLP, independent registered public accounting firm with respect to the Company within the meaning of the Securities Act, a letter, dated such a date, in form and substance reasonably satisfactory to you containing statements and information of the type customarily included in accountants’ “comfort letters” to underwriters with respect to the financial statements and certain financial information contained or incorporated by reference in the Registration Statement, the Time of Sale Prospectus and the Prospectus; provided that the letter delivered on the Closing Date or Additional Closing Date shall use a “cut-off” date no more than two business days prior to the Closing Date or such Additional Closing Date, as the case may be.

(b) The Registration Statement shall remain effective and at the Closing Date or the Additional Closing Date, as the case may be, no stop order suspending the effectiveness of the Registration Statement shall have been issued, no proceedings for such purpose shall have been instituted or, to the knowledge of the Company or you, shall be threatened by the Commission. The Prospectus and each issuer “free writing prospectus” shall have been timely filed with the Commission under the Securities Act, as required. All requests by the Commission for additional information relating to the offering of the Shares shall have been complied with to the reasonable satisfaction of the Purchasers.

(c) Subsequent to the date of this Agreement, there shall not have occurred (A) any change or any development involving a prospective change not contemplated by the Time of Sale Prospectus as of the date of this Agreement in or affecting the financial condition, business or properties of the Company and its subsidiaries taken as a whole or (B) (i) any downgrading in the rating of any debt securities or preferred stock of or guaranteed by the Company or any of its subsidiaries by any “nationally recognized statistical rating organization” (as defined in Section 3(a)(62) under the Exchange Act) or (ii) new or revised public announcement that any such organization has under surveillance or review its rating of any debt securities or preferred stock of or guaranteed by the Company or any of its subsidiaries (other than an announcement with positive implications of a possible upgrading, and no implication of a possible downgrading, of such rating) or any new or revised public announcement that the Company has been placed on negative outlook, which, in the case of clauses (A) and (B) above, in the judgment of the Purchasers that have severally agreed to purchase a majority of the Shares, materially impairs the investment quality of the Shares.

(d) You shall have received an opinion and a negative assurance letter, dated the Closing Date or the Additional Closing Date, as the case may be, of Kirkland & Ellis LLP, as counsel for the Company, in form and substance reasonably satisfactory to you.

(e) You shall have received an opinion and a negative assurance letter, dated the Closing Date or the Additional Closing Date, as the case may be, of Davis Polk & Wardwell LLP, as counsel for the Purchasers, with respect to such matters as you may reasonably request, and the Company shall have furnished to such counsel such documents as they reasonably request for the purpose of enabling them to pass on such matters.

(f) You shall have received a certificate of the Chief Executive Officer, President or any Vice President of the Company and a principal financial or accounting officer of the Company, dated the Closing Date or the Additional Closing Date, as the case may be, in which such officers shall state, to the best of their knowledge after reasonable investigation, (i) the representations and warranties of the Company in this Agreement are true and correct in all material respects, (ii) the Company has complied with all agreements and satisfied all conditions on its part to be performed or satisfied at or prior to the Closing Date, (iii) no stop order suspending the effectiveness of the Registration Statement has been issued and no proceedings for such purpose have been instituted, are pending or, to the best knowledge of the Company, threatened by the Commission, and (iv) that, subsequent to the date of the most recent financial statements set forth or incorporated by reference in the Time of Sale Prospectus or the Prospectus, there has been no material adverse change, nor any development or event reasonably likely to involve a prospective material adverse change, in the financial condition, business, properties or results of operations of the Company and its subsidiaries taken as a whole, except as set forth or contemplated in the Time of Sale Prospectus or the Prospectus.

(g) The Shares to be delivered on the Closing Date or the Additional Closing Date, as the case may be, shall have been approved for listing on the New York Stock Exchange, subject to official notice of issuance.

(h) The “lock-up” agreements, each substantially in the form of Schedule C to this Agreement, between you and certain officers and directors of the Company relating to sales and certain other dispositions of shares of Common Stock or certain other securities, delivered to you on or before the date hereof, shall be full force and effect on the Closing Date or the Additional Closing Date, as the case may be.

(i) The Company will furnish you with such conformed copies of such opinions, certificates, letters and documents as you reasonably request.

In case any such condition shall not have been satisfied on or prior to the Closing Date or the Additional Closing Date, as the case may be, this Agreement may be terminated by you with respect to, in the case of the Closing Date, the Shares and, in the case of the Additional Closing Date, the Option Shares, upon notice in writing or by telecopy to the Company without liability or obligation on the part of the Company or any Purchaser, except as set forth in Section 14 hereof.

10. Conditions of the Obligations of the Company. The obligations of the Company to sell and deliver the Firm Shares on the Closing Date or the Option Shares on the Additional Closing Date are subject to the following condition precedent:

(a) No stop order suspending the effectiveness of the Registration Statement shall have been issued and no proceedings for that purpose shall have been instituted or, to the knowledge of the Company or you, shall be threatened by the Commission.

If any such condition shall not have been satisfied on or prior to the Closing Date or the Additional Closing Date, as the case may be, then the Company shall be entitled, by notice in writing or by telecopy to you, to terminate this Agreement with respect to, in the case of the Closing Date, the Shares and, in the case of the Additional Closing Date, the Option Shares without any liability or obligation on the part of the Company or any Purchaser, except as set forth in Section 14 hereof.

11. Indemnification.

(a) The Company will indemnify and hold harmless each Purchaser, its affiliates (as such term is defined in Rule 501(b) under the Securities Act (each, an “Affiliate”)), each of its directors and officers and each person, if any, who controls any Purchaser within the meaning of the Securities Act or the Exchange Act against any losses, claims, damages or liabilities, joint or several, to which such Purchaser, Affiliate or such controlling person may become subject, under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in the Registration Statement,

the Time of Sale Prospectus, the Prospectus, any issuer “free writing prospectus” or any Written Testing-the-Waters Communication (or any amendment or supplement thereto), or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading; and will reimburse each Purchaser, Affiliate and each such controlling person for any legal or other expenses reasonably incurred by such Purchaser, Affiliate or such controlling person in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that the Company will not be liable to such Purchaser, Affiliate or controlling person in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in any such documents in reliance upon and in conformity with written information furnished to the Company by such Purchaser specifically for use therein, it being understood and agreed that the only such information furnished by any Purchaser consists of the information described as such in Section 11(b) hereof. This indemnity agreement will be in addition to any liability which the Company may otherwise have.

(b) Each Purchaser agrees, severally and not jointly, to indemnify and hold harmless the Company, each of its directors and officers and each person, if any, who controls the Company within the meaning of the Securities Act or the Exchange Act, against any losses, claims, damages or liabilities to which the Company or any such director, officer or controlling person may become subject, under the Securities Act, or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in the Registration Statement, the Time of Sale Prospectus, the Prospectus, any issuer “free writing prospectus” as defined in Rule 433(h) under the Act, any Written Testing-the-Waters Communication, any Company information that the Company has filed, or is required to file, pursuant to Rule 433(d) under the Act or the Prospectus (or any amendment or supplement thereto) or arise out of or are based upon the omission or the alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with written information furnished to the Company by such Purchaser specifically for use therein, it being understood and agreed upon that the only such information furnished by any Purchaser consists of the following information in the Prospectus: the concession figure appearing in the fifth paragraph under the caption “Underwriting” and the information contained in the twelfth, thirteenth and fourteenth paragraphs under the caption “Underwriting”; and will reimburse any legal or other expenses reasonably incurred by the Company or any such director, officer or controlling person in connection with investigating or defending any such loss, claim, damage, liability or action as such expenses are incurred. 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 Securities 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 Shares (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 Shares 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 Shares. 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 underwriting discounts and commissions received by such 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.

12. Default of Purchasers. If, on the Closing Date or the Additional Closing Date, as the case may be, any Purchaser or Purchasers default in their obligations to purchase the Shares that it has agreed to purchase hereunder on such date and the aggregate principal amount of the Shares which such defaulting Purchaser or Purchasers agreed but failed to purchase is 10% or less of the aggregate number Shares to be purchased by all Purchasers on such date, the non-defaulting Purchasers may make arrangements satisfactory to the Company for the purchase of such Shares by other persons, including any of the Purchasers, but if no such arrangements are made by the Closing Date or the Additional Closing Date, as the case may be, the non-defaulting Purchasers shall be obligated severally, in proportion to their respective commitments hereunder, to purchase the Shares which such defaulting Purchasers agreed but failed to purchase on such date. If any Purchaser or Purchasers so default and the aggregate number of Shares 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 Shares by other persons are not made within seventy-two hours after such default, this Agreement or, with respect to any Additional Closing Date, the obligation of the Purchasers to purchase Shares on the Additional Closing Date, as the case may be, will terminate without liability on the part of any non-defaulting Purchaser or the Company, except as provided in Section 14. In the event that any Purchaser or Purchasers default in their obligation to purchase Shares hereunder, the Company may, by prompt written notice to the non-defaulting Purchasers, postpone the Closing Date or the Additional Closing Date, as the case may be, 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.

13. 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 or, in the case of the Option Shares, prior to the Additional 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 Shares on the Closing Date or the Additional Closing Date, as the case may be, on the terms and in the manner contemplated by this Agreement, the Time of Sale Prospectus and the Prospectus.

14. 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 Shares. If this Agreement is terminated pursuant to Section 9, 10, 12 or 13 or if for any reason the purchase of the Shares by the Purchasers is not consummated, the Company shall remain responsible for the expenses to be paid or reimbursed by it pursuant to Section 7(h). In addition, in such event, the respective obligations of the Company and the Purchasers pursuant to Section 11 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 Shares 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.

15. Notices. All communications hereunder will be in writing, and, if sent to the Purchasers will be delivered or telecopied and confirmed to Goldman Sachs & Co. LLC, 200 West Street, New York, New York 10282, Attention: Registration Department, fax: (212) 902-9316; BofA Securities, Inc., One Bryant Park, New York, New York 10036, Attention: Syndicate Department, with a copy to: Attention: ECM Legal; Citigroup Global Markets Inc., 388 Greenwich Street, New York NY 10013, Attention: General Counsel, fax: (646) 291-1469; and J.P.

16. Successors. This 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 11, and no other person will have any right or obligation hereunder.

17. 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 AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY.

18. 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 Shares, 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 Shares.

19. Relationship. The Company acknowledges that in connection with the offering of the Shares, (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 Shares.

20. Construction. This 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.

21. 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. Counterparts may be delivered via facsimile, electronic mail (including any electronic signature covered by the U.S. federal ESIGN Act of 2000, Uniform Electronic Transactions Act, the Electronic Signatures and Records Act or other applicable law, e.g., www.docusign.com) or other transmission method and any counterpart so delivered shall be deemed to have been duly and validly delivered and be valid and effective for all purposes.

22. 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.

23. Recognition of the U.S. Special Resolution Regimes.

(a) In the event that any Purchaser that is a Covered Entity becomes subject to a proceeding under a U.S. Special Resolution Regime, the transfer from such Purchaser of this Agreement, and any interest and obligation in or under this Agreement, will be effective to the same extent as the transfer would be effective under the U.S. Special Resolution Regime if this Agreement, and any interest and obligation in or under this Agreement, were governed by the laws of the United States or a state of the United States.

(b) In the event that any Purchaser that is a Covered Entity or a BHC Act Affiliate of such Purchaser becomes subject to a proceeding under a U.S. Special Resolution Regime, Default Rights under this Agreement that may be exercised against such Purchaser are permitted to be exercised to no greater extent than such Default Rights could be exercised under the U.S. Special Resolution Regime if this Agreement were governed by the laws of the United States or a state of the United States.

(c) As used in this Section 23:

“BHC Act Affiliate” has the meaning assigned to the term “affiliate” in, and shall be interpreted in accordance with, 12 U.S.C. § 1841(k).

In consideration of the agreement by the Purchasers to offer and sell the Securities, and of other good and valuable consideration the receipt and sufficiency of which is hereby acknowledged, the undersigned agrees that, during the period beginning from the date of this Lock-Up Agreement and continuing to and including the date 90 days after the date of the final prospectus relating to the Public Offering (the “Prospectus”) (such period, the “Lock-Up Period”), the undersigned shall not, and shall not cause or direct any of its affiliates to, (i) offer, sell, contract to sell, pledge, grant any option, right or warrant to purchase, purchase any option or contract to sell, lend or otherwise transfer or dispose of any shares of Common Stock, or any options or warrants to purchase any shares of Common Stock, or any securities convertible into, exchangeable for or that represent the right to receive shares of Common Stock (such shares of Common Stock, options, rights, warrants or other securities, collectively, “Lock-Up Securities”), including without limitation any such Lock-Up Securities now owned or hereafter acquired by the undersigned, (ii) engage in any hedging or other transaction or arrangement (including, without limitation, any short sale or the purchase or sale of, or entry into, any put or call option, or combination thereof, forward, swap or any other derivative transaction or instrument, however described or defined) which is designed to or which reasonably could be expected to lead to or result in a sale, loan, pledge or other disposition (whether by the undersigned or someone other than the undersigned),

or transfer of any of the economic consequences of ownership, in whole or in part, directly or indirectly, of any Lock-Up Securities, whether any such transaction or arrangement (or instrument provided for thereunder) would be settled by delivery of Common Stock or other securities, in cash or otherwise (any such sale, loan, pledge or other disposition, or transfer of economic consequences, a “Transfer”), (iii) make any demand for or exercise any right with respect to the registration of any Lock-Up Securities or (iv) otherwise publicly announce any intention to engage in or cause any action, activity, transaction or arrangement described in clause (i), (ii) or (iii) above. The undersigned represents and warrants that the undersigned is not, and has not caused or directed any of its affiliates to be or become, currently a party to any agreement or arrangement that provides for, is designed to or reasonably could be expected to lead to or result in any Transfer during the Lock-Up Period.

Notwithstanding the foregoing, the undersigned may:

provided that (A) in the case of clauses (a)(i), (ii), (iii), (iv) and (v) above, (x) such transfer or distribution shall not involve a disposition for value and (y) it shall be a condition to the transfer or distribution that the donee, devisee, transferee or distributee, as the case may be, shall sign and deliver a lock-up agreement in the form of this Lock-Up Agreement, and (C) in the case of clauses (a)(i), (ii), (iii), (iv), (v), (vii), (viii), (ix), (x) and (xi) above, no filing by any party (including, without limitation, any donor, donee, devisee, transferor, transferee, distributor or distributee) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or other public filing, report or announcement shall be voluntarily made during the Lock-Up Period and, if any such filing, report or announcement shall be legally required during the Lock-Up Period, such filing, report or announcement shall clearly indicate in the footnotes thereto (A) the circumstances of such transfer or distribution and (B) in the case of a transfer or distribution pursuant to clauses (a)(i), (ii), (iii), (iv), (v) and (vii) above, that the donee, devisee, transferee or distributee has agreed to be bound by a lock-up agreement in the form of this Lock-Up Agreement;

The undersigned now has, and, except as contemplated by clauses (a) and (c) of the third paragraph of this Lock-Up Agreement, for the duration of this Lock-Up Agreement will have, good and marketable title to the undersigned’s Lock-Up Securities, free and clear of all liens, encumbrances and claims whatsoever. The undersigned also agrees and consents to the entry of stop transfer instructions with the Company’s transfer agent and registrar against the transfer of the undersigned’s Lock-Up Securities except in compliance with the foregoing restrictions.

The undersigned further acknowledges and agrees that, although the Purchasers may have provided or hereafter provide to the undersigned in connection with the Public Offering a Form CRS and/or certain other disclosures as contemplated by Regulation Best Interest, the Purchasers have not made and are not making a recommendation to the undersigned to enter into this Lock-Up Agreement or to transfer, sell or dispose of, or to refrain from transferring, selling or disposing of, any Lock-Up Securities, and nothing set forth in such disclosures or herein is intended to suggest that any Purchaser is making such a recommendation.

This Lock-Up Agreement shall automatically terminate and the undersigned shall be released from all of his, her or its obligations hereunder upon the earlier of (i) the date on which for any reason the Underwriting Agreement is terminated (other than the provisions thereof that survive termination) prior to payment for and delivery of the Securities to be sold thereunder (other than pursuant to the Purchasers’ option thereunder to purchase additional Securities), (ii) the date on which the Company notifies the Representatives, in writing and prior to the execution of the Underwriting Agreement, that it does not intend to proceed with the Public Offering and (iii) November 29, 2024, in the event that the Underwriting Agreement has not been executed by such date (provided, however, that the Company may, by written notice to the undersigned prior to such date, extend such date by a period of up to an additional 90 days).

We have also assumed that the execution and delivery of the Underwriting Agreement and the performance by the Company of its obligations thereunder do not and will not violate, conflict with or constitute a default under any agreement or instrument to which the Company is bound.

We do not find it necessary for the purposes of this opinion, and accordingly we do not purport to cover herein, the application of the securities or “blue sky” laws of the various states to the sale of the Shares.

This opinion is limited to the specific issues addressed herein, and no opinion may be inferred or implied beyond that expressly stated herein.

The dividend rate, conversion terms and other terms of the Preferred Stock will be determined at the time of pricing of the offering of the Depositary Shares. Currently, there is no public market for the Depositary Shares or the Preferred Stock. Boeing intends to apply to list the Depositary Shares on the New York Stock Exchange under the symbol “BA.PRA.”

Boeing Announces Pricing of Upsized Concurrent Offerings of Common Stock and Depositary Shares

ARLINGTON, Va., October 28, 2024 /PRNewswire/ – The Boeing Company [NYSE: BA] (“Boeing” or the “Company”) announced today the pricing of its previously announced separate underwritten public offerings of (i) 112,500,000 shares of common stock, par value $5.00 per share (“Common Stock”), of the Company at a public offering price of $143.00 per share (the “Common Stock Offering”) and (ii) $5 billion of depositary shares (“Depositary Shares”), each representing a 1/20th interest in a share of newly issued 6.00% Series A Mandatory Convertible Preferred Stock, par value $1.00 per share (“Preferred Stock”) at a public offering price of $50.00 per Depositary Share (the “Depositary Shares Offering” and, together, the “Offerings”). Boeing has granted the underwriters in each respective offering a 30-day option to purchase up to an additional (i) 16,875,000 shares of Common Stock and (ii) $750 million of Depositary Shares, solely to cover over-allotments, if any, in each case at the public offering price less the applicable underwriting discount. The Common Stock Offering is expected to close on October 30, 2024 and the Depositary Shares Offering is expected to close on October 31, 2024, subject to customary closing conditions.

The net proceeds from the Common Stock Offering will be approximately $15.81 billion (assuming the underwriters do not exercise the option to purchase additional shares of Common Stock) and the net proceeds from the Depositary Shares Offering will be approximately $4.91 billion (assuming the underwriters do not exercise the over-allotment option to purchase additional Depositary Shares), in each case after deducting the applicable underwriting discount and estimated offering expenses payable by Boeing. Boeing intends to use the net proceeds from the Offerings for general corporate purposes, which may include, among other things, repayment of debt, additions to working capital, capital expenditures, and funding and investments in the Company’s subsidiaries.

Holders of the Depositary Shares will be entitled to a proportional fractional interest in the rights and preferences of the Preferred Stock, including conversion, dividend, liquidation and voting rights, subject to the provisions of a deposit agreement. The Preferred Stock will accumulate dividends (which may be paid in cash or, subject to certain limitations, in shares of Common Stock or in any combination of cash and Common Stock) at a rate per annum equal to 6.00% on the liquidation preference thereof, which is $1,000 per share, payable when, as and if declared by Boeing’s board of directors (or an authorized committee thereof), on January 15, April 15, July 15 and October 15 of each year, beginning on January 15, 2025 and ending on, and including, October 15, 2027. Unless earlier converted, each outstanding share of Preferred Stock will automatically convert for settlement on or about October 15, 2027, into between 5.8280 and 6.9940 shares of Common Stock (and, correspondingly, each Depositary Share will automatically convert into between 0.2914 and 0.3497 shares of Common Stock), subject to customary anti-dilution adjustments, determined based on the volume-weighted average price of the Common Stock over the 20 consecutive trading day period beginning on, and including, the 21st scheduled trading day prior to October 15, 2027. Other than during a fundamental change conversion period (as defined in the prospectus supplement relating to the Depositary Shares Offering), at any time prior to the mandatory conversion settlement date, a holder of 20 Depositary Shares may cause the bank depositary to convert one share of Preferred Stock, on such holder’s behalf, into a number of shares of Common Stock equal to the minimum conversion rate of 5.8280, subject to certain anti-dilution and other adjustments. Currently, there is no public market for the Depositary Shares or the Preferred Stock. Boeing has applied to list the Depositary Shares on the New York Stock Exchange under the symbol “BA-PRA.”

Goldman Sachs & Co. LLC, BofA Securities, Citigroup and J.P. Morgan are acting as lead joint bookrunning managers for the Offerings. Wells Fargo Securities, BNP PARIBAS, Deutsche Bank Securities, Mizuho, Morgan Stanley, RBC Capital Markets and SMBC Nikko are also acting as joint bookrunning managers for the Offerings.

Caution Concerning Forward-Looking Statements

This press release contains “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. Words such as “may,” “should,” “expects,” “intends,” “projects,” “plans,” “believes,” “estimates,” “targets,” “anticipates,” and other similar words or expressions, or the negative thereof, generally can be used to help identify these forward-looking statements. Examples of forward-looking statements include statements relating to the offerings of Common Stock, Preferred Stock and Depositary Shares, our ability to complete the Offerings on the anticipated timeline or at all and the anticipated use of the net proceeds therefrom, as well as any other statement that does not directly relate to any historical or current fact. Forward-looking statements are based on expectations and assumptions that we believe to be reasonable when made, but that may not prove to be accurate. These statements are not guarantees and are subject to risks, uncertainties, and changes in circumstances that are difficult to predict. Many factors could cause actual results to differ materially and adversely from these forward-looking statements. Among these factors are risks related to: (1) general conditions in the economy and our industry, including those due to regulatory changes; (2) our reliance on our commercial airline customers; (3) the overall health of our aircraft production system, production quality issues, commercial airplane production rates, our ability to successfully develop and certify new aircraft or new derivative aircraft, and the ability of our aircraft to meet stringent performance and reliability standards; (4) our pending acquisition of Spirit AeroSystems Holdings, Inc. (Spirit), including the satisfaction of closing conditions in the expected timeframe or at all, (5) changing budget and appropriation levels and acquisition priorities of the U.S. government, as well as significant delays in U.S. government appropriations; (6) our dependence on our subcontractors and suppliers, as well as the availability of highly skilled labor and raw materials; (7) work

stoppages or other labor disruptions; (8) competition within our markets; (9) our non-U.S. operations and sales to non-U.S. customers; (10) changes in accounting estimates; (11) realizing the anticipated benefits of mergers, acquisitions, joint ventures/strategic alliances or divestitures, including anticipated synergies and quality improvements related to our pending acquisition of Spirit; (12) our dependence on U.S. government contracts; (13) our reliance on fixed-price contracts; (14) our reliance on cost-type contracts; (15) contracts that include in-orbit incentive payments; (16) unauthorized access to our, our customers’ and/or our suppliers’ information and systems; (17) potential business disruptions, including threats to physical security or our information technology systems, extreme weather (including effects of climate change) or other acts of nature, and pandemics or other public health crises; (18) potential adverse developments in new or pending litigation and/or government inquiries or investigations; (19) potential environmental liabilities; (20) effects of climate change and legal, regulatory or market responses to such change; (21) credit rating agency actions and changes in our ability to obtain debt financing on commercially reasonable terms, at competitive rates and in sufficient amounts; (22) substantial pension and other postretirement benefit obligations; (23) the adequacy of our insurance coverage; and (24) customer and aircraft concentration in our customer financing portfolio.

Additional information concerning these and other factors can be found in our filings with the Securities and Exchange Commission, including our most recent Annual Report on Form 10-K, Quarterly Reports on Form 10-Q and Current Reports on Form 8-K. Any forward-looking statement speaks only as of the date on which it is made, and we assume no obligation to update or revise any forward-looking statement, whether as a result of new information, future events, or otherwise, except as required by law.
