Form of International Notice of Terms of Long-Term Incentive Performance Restricted Stock Units (Stock-Settled)

As part of its executive compensation program, The Boeing Company (the “Company”) has awarded you a Performance Restricted Stock Unit award (the “Award”) pursuant to The Boeing Company 2023 Incentive Stock Plan, as amended and restated from time to time (the “Plan”), and the provisions contained herein (the “Notice”). Capitalized terms not otherwise defined in this Notice shall have the meaning ascribed to them in the Plan. Your Award is subject to the terms of the Plan. If there is any inconsistency between the terms of this Notice and the terms of the Plan, the Plan’s terms shall control. You are required to accept and acknowledge the terms and conditions of the Award, through the mechanism and procedures determined by the Company, as a condition to receiving the Award. The terms and conditions of the Award are as follows:

1. PRSU Award. You have been awarded « PRSU #» Restricted Stock Units (“ PRSUs”). Each PRSU corresponds to one share of Common Stock.

2. PRSU Account. The Company will maintain a record of the number of awarded PRSUs in an account established in your name.

3. Vesting of PRSUs.

3.1 Subject to Sections 6 and 7, you will vest in a percentage of your PRSUs based on the level of the Company’s performance against a pre-set financial performance measure and as may be adjusted pursuant to Section 3.3 (such percentage, the “Earned PRSUs”) on the third anniversary of the Grant Date, or, if such date is not a date on which the New York Stock Exchange is open for trading, the next following trading day (the “Vesting Date”). As soon as reasonably practicable following the Vesting Date, you shall receive a number of shares of Common Stock equal to the number of Earned PRSUs that vest as of such date. Notwithstanding the foregoing, the Earned PRSUs may be settled in the form of: (a) cash, to the extent settlement in shares of Common Stock (i) is not standard Company practice in your country of employment, (ii) is prohibited under applicable laws, (iii) would require you, the Company or, if different, the Related Company that employs you (the “Employer”) to obtain the approval of any governmental and/or regulatory body in your country of residence (and country of employment, if different), or (iv) is administratively burdensome; or (b) shares of Common Stock, but the Company may require you to immediately sell such shares if necessary to comply with applicable laws (in which case, you hereby expressly authorize the Company to issue sales instructions in relation to such shares on your behalf). If, after the Grant Date but prior to the Vesting Date, you transfer employment to a Related Company in another country (you will be considered to have transferred to a Related Company if you are paid through that Related Company’s payroll) and the Company does not settle Earned PRSUs in shares of Common Stock in that country, the Earned PRSUs will be settled in cash, calculated based on an applicable currency conversion methodology or policy as may be established by the Company from time to time, less any required withholdings pursuant to Section 11 of this Notice.

3.2 The Performance Goal used for purposes of determining the percentage of your PRSUs that will become Earned PRSUs is the Company’s cumulative free cash flow over the period January 1, 2024 through December 31, 2026 (the “Performance Period”). Performance under this Performance Goal will be assigned a percentage-based payout score based on a curve established by the Compensation Committee of the Company’s Board of Directors (the “Committee”) as of the Grant Date, with 50% corresponding to performance at threshold, 100% corresponding to performance at target, 200% corresponding to performance at or above maximum, and 0% corresponding to performance below threshold. Straight line interpolation will be applied to determine the payout score for performance between threshold and target, and between target and maximum. The Committee retains discretion to calculate the Company’s actual performance to exclude the impact of nonrecurring items deemed not reflective of the Company’s core operating performance, including, but not limited to,

exogenous events, acquisitions, divestitures, changes in accounting principles, or “extraordinary items” determined under generally accepted accounting principles. The payout score shall be further subject to downward adjustment as described in Section 3.3.

3.3 If the product safety goals established by the Committee with respect to these PRSUs as of the Grant Date are certified by the Committee, as advised by the Aerospace Safety Committee of the Company’s Board of Directors, as being complete (the “Certification”) no later than December 31, 2024, the payout score shall not be adjusted downward pursuant to this Section. However, the payout score shall be subject to downward adjustment in the following circumstances:

–If the Certification occurs on or after January 1, 2025 but before December 31, 2025, the payout score shall be reduced by 25%.

–If the Certification occurs on or after January 1, 2026, or otherwise does not occur prior to the Vesting Date, the payout score shall be reduced to 0%.

3.4 Subject to the terms and conditions outlined under Sections 6 and 7, this Award is granted on the condition that you remain continuously employed by the Company or a Related Company from the Grant Date through the Vesting Date.

4. Dividend Equivalents.

4.1 While PRSUs are in your account, they will earn dividend equivalents in the form of additional PRSUs. Specifically, as of each dividend payment date for Common Stock, your PRSU account will be credited with additional PRSUs (“dividend equivalent PRSUs”) equal in number to the number of shares of Common Stock that could be bought with the cash dividends that would be paid on the PRSUs in your account if each PRSU were one share of Common Stock on the applicable dividend payment date.

4.2 The number of shares of Common Stock that could be bought with the cash dividends will be calculated to two decimal places and will be based on the “Fair Market Value” of a share of Common Stock on the applicable dividend payment date. For purposes of this Award, “Fair Market Value” means the average of the high and the low per share trading prices for Common Stock as reported by The Wall Street Journal for the specific dividend payment date, or by such other source as the Company deems reliable.

4.3 Dividend equivalent PRSUs will vest at the same time and in the same manner as the PRSUs with which they are associated and will be subject to the same terms as the PRSUs. For the avoidance of doubt, credited dividend equivalent PRSUs in your account will be subject to adjustment in accordance with the payout score determined under Section 3.2. All references to PRSUs in this Notice shall be deemed to include any credited dividend equivalent PRSUs, except where the context clearly indicates otherwise.

5. Adjustment in Number of PRSUs. The number of PRSUs in your account will be adjusted proportionately for any increase or decrease in the number of issued shares of Common Stock resulting from any stock split, combination or exchange of Common Stock, consolidation, spin-off or recapitalization of Common Stock, or any similar capital adjustment or the payment of any stock dividend.

6. Impact of Certain Terminations.

6.1 In the event your employment is terminated prior to the Vesting Date by reason of (i) death, (ii) disability, or (iii) retirement or layoff on or after attaining age 62 with at least one year of service, and provided (in the case of retirement) that you have given the Company sufficient advance notice of your retirement (i.e., at least 60 days), you will remain eligible to vest in, and receive distribution of, your PRSUs in accordance with Section 3 as though you had continued employment through the Vesting Date. For purposes of this Award, “disability” means a disability entitling you to benefits under any long-term disability policy sponsored by the Company or a Related Company, or as such term is required to be defined for these purposes under applicable local law.

6.2 In the event your employment is terminated prior to the Vesting Date by reason of (i) retirement on or after attaining age 55 with at least ten years of service or under conditions that satisfy the requirements for “retirement” under a defined benefit pension plan maintained by the Company or a Related Company in which you participate, (ii) permanent termination of employment in compliance with a government-mandated or employer-mandated requirement to retire upon reaching a certain age, or (iii) layoff (in each case, prior to attaining at least age 62 with at least one year of service), your PRSUs will be prorated based on the number of full and partial calendar months you spent on the active payroll during the vesting period (beginning with the first full calendar month after the Grant Date). You will

remain eligible to vest in, and receive distribution of, your pro-rated PRSUs in accordance with Section 3 as though you had continued employment through the Vesting Date.

7. Forfeiture Upon Other Terminations. In the event your employment is terminated prior to the Vesting Date for any reason (including for cause and resignation prior to retirement eligibility) other than those reasons described in Section 6, all unvested PRSUs shall immediately be forfeited and canceled without consideration.

8. Leave of Absence. Any leave of absence period that does not extend beyond three full calendar months, or any longer leave of absence period during which you have a right to reemployment with the Company or a Related Company that is guaranteed by contract or applicable law (in both cases, an “Excepted Leave”), shall have no impact on your Award. Unless otherwise required by applicable law, in the event you have an authorized leave of absence at any time during the vesting period which absence extends beyond the Excepted Leave period (including any absence that began before the Grant Date), your PRSUs will be prorated based on the number of full and partial calendar months in excess of the Excepted Leave period that you were on leave of absence, as compared against the number of full and partial calendar months during the vesting period (beginning with the first full calendar month after the Grant Date).

9. Transferability. PRSUs are not transferable except by will or by laws of descent and distribution. You may designate a beneficiary to receive your Award in the event of your death. To be valid, a beneficiary designation with respect to your Award must be properly submitted through the Stock Plan Administrator in accordance with the Stock Plan Administrator’s procedures. The current Stock Plan Administrator is Fidelity Stock Plan Services, LLC and certain of its affiliated entities.

10. Clawback and Forfeiture Policy.

10.1 This Award and any gross proceeds resulting from the vesting of this Award are subject to the Clawback Policy adopted by the Company’s Board of Directors, as amended from time to time (the “Policy”). The Policy provides (among other things) that an Award may be subject to clawback and forfeiture (meaning that the Award or gross proceeds thereof must be promptly returned to the Company if already distributed, or that you will lose your entitlement to an Award if it has not yet been distributed) in the discretion of the Committee, if the Committee determines that you have (i) violated, or engaged in negligent conduct in connection with the supervision of someone who violated, any Company policy, law, or regulation that has compromised the safety of any of the Company’s products or services and has, or reasonably could be expected to have, a material adverse impact on the Company, the Company’s customers or the public; or (ii) engaged in fraud, bribery, or illegal acts like fraud or bribery, or knowingly failed to report such acts of an employee over whom you had direct supervisory responsibility. The Policy further contains provisions regarding the recovery of certain “covered compensation” (as defined in the Policy) as required pursuant to New York Stock Exchange listing standards and the Section 10D of the Securities Exchange Act of 1934, as amended, and any rules, regulations, or listing standards issued to implement the foregoing from time to time. In accepting this Award, you acknowledge that you have read the Policy, available at https://www.boeing.com/resources/boeingdotcom/principles/ethics_and_ compliance/pdf/clawback-policy.pdf, that you understand its applicability to you, and that you agree to comply with the terms and conditions of the Policy as they may be applied to you.

10.2 In addition, subject to applicable law, or except as may be otherwise provided in the Addendum, this Award and any gross proceeds resulting from the vesting of this Award are subject to clawback and forfeiture in the event you engage in any of the following conduct, as determined by the Company or its delegate in its sole discretion, prior to the second anniversary of the later of the Vesting Date or receipt of payment of the Award: you (i) plead or admit to, are convicted of, or are otherwise found guilty of a criminal or indictable offense involving theft, fraud, embezzlement, or other similar unlawful acts against the Company or against the Company’s interests; (ii) directly or indirectly engage in competition with any aspect of Company business with which you were involved or about which you gained Company proprietary or confidential information; (iii) induce or attempt to induce, directly or indirectly, any of the Company’s employees, representatives or consultants to terminate, discontinue or cease working with or for the Company, or to breach any contract with the Company, in order to work with or for, or enter into a contract with, you or any third party; (iv) disparage or defame the Company or its products or current or former employees, provided that this clause shall not be construed to prohibit any individual from reporting, in good faith, suspected unlawful conduct in the workplace; or (v) take, misappropriate, use or disclose Company proprietary or confidential information. Clawback can, if

possible and where permitted by local law, be made by deducting payments that will become due in the future (including salary, bonuses, or share awards). Your acceptance of this Award shall constitute your acknowledgement and recognition that your compliance with this Section 10 is a condition for your receipt of this Award. For purposes of this Section 10, the Company shall include the Company and all Related Companies.

10.3 Nothing in this Section 10 will apply to legally protected communications to government agencies or statements made in the course of sworn testimony in administrative, judicial or arbitral proceedings.

10.4 The restrictions in this Section 10 are considered by the parties to be fair and reasonable in all circumstances and the parties agree that the restrictions are reasonable and necessary to protect the Company’s legitimate business interests. Each of the restrictions contained in this Section, including the sub-paragraphs and sub-clauses thereof, constitutes an entirely separate, severable and independent restriction. If any restriction is found to be invalid this will not affect the validity or enforceability of any of the other restrictions. It is agreed that if any such restrictions by themselves, or taken together, are for any reason unenforceable, but would be enforceable if part or parts of the wording were deleted, the relevant restriction or restrictions shall apply with such deletion(s) as may be necessary to make it or them valid and enforceable.

11. Tax Withholding. Subject to the terms of the Plan and as a condition to the grant of the PRSUs, you acknowledge and agree that, regardless of any action taken by the Company or the Employer, the ultimate liability for all income tax, social insurance, payroll tax, fringe benefits tax, payment on account or other tax-related items related to your participation in the Plan and legally applicable to you (“Tax-Related Items”), is and remains your responsibility and may exceed the amount actually withheld by the Company or the Employer. You further acknowledge that the Company and/or the Employer (a) make no representations or undertakings regarding the treatment of any Tax-Related Items in connection with any aspect of the PRSUs, including, but not limited to, the grant, vesting or payment of the PRSUs; and (b) do not commit to and are under no obligation to structure the terms of the grant or any aspect of the PRSUs to reduce or eliminate your liability for Tax-Related Items or achieve any particular tax result. If your country of employment (and/or the country of residence, if different) requires withholding of Tax-Related Items, then prior to the issuance and delivery of any shares of Common Stock or cash upon the vesting of this Award, the Company, the Employer, or any plan administrator, as applicable: (x) shall withhold a sufficient number of shares of Common Stock otherwise issuable upon the vesting of this Award that have an aggregate Fair Market Value sufficient to pay the Tax-Related Items required to be withheld (in which case, the cash equivalent of such withheld shares of Common Stock shall be used to settle the withholding obligation); or (y) shall withhold an amount from your regular salary and/or wages, or from any other amounts payable to you, equal to the Tax-Related Items required to be withheld.

Depending on the withholding method, the Company, the Employer, or any plan administrator, as applicable, may withhold or account for Tax-Related Items by considering applicable statutory withholding rates, but such withholding shall not exceed an amount of withholding based on the maximum statutory rates in your applicable tax jurisdiction(s) (unless a lesser amount of withholding is required to avoid the classification of this Award as a liability on the Company’s consolidated balance sheet or other adverse accounting treatment).

In the event the withholding requirements are not satisfied through the withholding of shares of Common Stock or through your regular salary and/or wages or other amounts payable to you, no shares of Common Stock will be issued to you and no cash payment will be made unless and until satisfactory arrangements (as determined by the Company or its delegate) have been made by you with respect to the payment of any Tax-Related Items which the Company determines, in its sole discretion, must be withheld or collected with respect to this Award. If you are subject to taxation in more than one jurisdiction, you acknowledge that the Company and/or the Employer may be required to withhold or account for Tax-Related Items in more than one jurisdiction. By accepting the grant of this Award, you expressly consent to the withholding of shares of Common Stock and/or the withholding of amounts from your regular salary and/or wages, or other amounts payable to you, as provided for hereunder. All other Tax-Related Items related to this Award and any shares of Common Stock or cash acquired pursuant to the vesting of this Award are your sole responsibility.

If you are (a) a director of a Related Company incorporated in Australia, or (b) a person who is a management-level executive of a Related Company incorporated in Australia and who also is a director of a Related Company incorporated outside of Australia, the grant of the Award is conditioned upon satisfaction of the shareholder approval provisions of section 200B of the Corporations Act 2001 (Cth) in Australia.

2. Securities Law Information. This grant is being made under Division 1A, Part 7.12 of the Australia Corporations Act (Cth). Please note that if you offer shares of Common Stock for sale to a person or entity resident in Australia, the offer may be subject to disclosure requirements under

Australian law. You should obtain legal advice on the relevant disclosure obligations prior to making any such offer.

1. Settlement in Shares. Notwithstanding anything to the contrary in the Notice, Addendum or the Plan, your PRSUs shall be settled only in Common Stock (and may not be settled in cash).

2. Clawback and Forfeiture Policy. The following provision shall replace Section 10.2 of the Notice:

10.2. In addition, subject to applicable law, this Award and any gross proceeds resulting from the vesting of this Award are subject to clawback and forfeiture in the event you engage in any of the following conduct, as determined by the Company or its delegate in its sole discretion, prior to the second anniversary of the later of the Vesting Date or receipt of payment of the Award: you (i) plead or admit to, are convicted of, or are otherwise found guilty of a criminal or indictable offense involving theft, fraud, embezzlement, or other similar unlawful acts against the Company or against the Company’s interests; (ii) directly or indirectly engage, within Canada, in competition with any aspect of Company business with which you were directly involved or about which you gained proprietary or confidential information during the twenty-four (24) months before the date you engaged in such competitive activity; (iii) induce or attempt to induce, directly or indirectly, any of the Company’s employees, representatives or consultants, with whom you engaged on behalf of the Company during the twenty-four (24) months before the date of such inducement, to terminate, discontinue or cease working with or for the Company, or to breach any contract with the Company, in order to work with or for, or enter into a contract with, you or any third party; (iv) disparage or defame the Company or its products or current or former employees, provided that this clause shall not be construed to prohibit any individual from reporting, in good faith, suspected unlawful conduct in the workplace; or (v) take, misappropriate, use or disclose Company proprietary or confidential information. Clawback can, if possible and where permitted by local law, be made by deducting payments that will become due in future (including salary, bonuses, or share awards). Your acceptance of this Award shall constitute your acknowledgement and recognition that your compliance with this Section 10 is a condition for your receipt of this Award. For purposes of this Section 10, the Company shall include the Company and all Related Companies.

3. Termination of Employment. The following provision shall supplement Section 6 of the Notice:

In the event of your termination of employment for any reason (other than by reason of death, disability or retirement), either by you or by the Employer, with or without cause, your right to vest or to continue to vest in the PRSUs and receive shares of Common Stock under the Plan, if any, will terminate as of the actual Date of Termination. For this purpose, the “Date of Termination” shall mean the earlier of (1) the date your employment with the Employer is terminated for any reason; or (2) the date you receive written notice of termination from the Employer, as determined in the Company's sole discretion and shall not include or be extended by any period following such day during which you are in receipt of or eligible to receive any notice of termination, pay in lieu of notice of termination, severance pay or any other payments or damages, whether arising under statute, contract or at common law. For greater certainty, you will not earn or be entitled to any pro-rated vesting for the portion of time before the date on which your right to vest terminates, nor will you be entitled to any compensation for lost vesting.

Notwithstanding the foregoing, if applicable employment standards legislation explicitly requires continued entitlement to vesting during a statutory notice period, your right to vest in the PRSUs under the Plan, if any, will terminate effective as of the last day of your minimum statutory notice period, but you will not earn or be entitled to pro-rated vesting if the vesting date falls after the end of your statutory notice period, nor will you be entitled to any compensation for lost vesting.

If you are a resident of the Province of Quebec, the following provision shall apply:

4. French Language Documents. A French translation of this document and the Plan will be made available to you as soon as reasonably practicable upon your written request. Notwithstanding anything to the contrary in the Notice, and unless you indicate otherwise, the French translation of this document and the Plan will govern your participation in the Plan.

1. Clawback and Forfeiture Policy. The following shall modify Section 10.2 of the Notice:

Clauses (ii) and (iii) of Section 10.2 shall not apply.

This Award and any gross proceeds resulting from the vesting of this Award are also subject to clawback and forfeiture in the event you engage in any of the following conduct, as determined by the Company or its delegate in its sole discretion, within the Restricted Period: directly or indirectly, for your own benefit or that of others, (a) be employed by or otherwise provide services to a Competing Business which is being carried out or to be carried out in any Restricted Territory; (b) set up or carry on a Competing Business which is being carried out or to be carried out in any Restricted Territory; (c) solicit, attempt to solicit, assist in soliciting, entice away, or try to entice away, from the Company or any Related Company any Key Person; or (d) be personally involved to a material extent in accepting into employment, recruiting, engaging, or otherwise using the services of any Key Person. For the avoidance of doubt, none of the restrictions contained in this Section prevent you from holding any shares or other securities in any company or from doing anything for which the Company has given its prior written consent. The Company encourages you to seek such consent if necessary.

The restrictions this Section are considered by the parties to be fair and reasonable in all circumstances. Each of the restrictions contained in this Section, including the sub-paragraphs and sub-clauses thereof, constitutes an entirely separate, severable and independent restriction. If any restriction is found to be invalid this will not affect the validity or enforceability of any of the other restrictions. It is agreed that if any such restrictions by themselves, or taken together, are for any reason unenforceable, but would be enforceable if part or parts of the wording were deleted, the relevant restriction or restrictions shall apply with such deletion(s) as may be necessary to make it or them valid and enforceable.

For the purposes of this Section, any capitalized terms shall have the following meaning:

“Competing Business” means any business which competes with or is preparing to compete with (a) any business carried on by the Company or any Related Company; or (b) any business which the Company or any Related Company is proposing to carry on and has taken material steps towards conducting; and in each of cases (a) and (b) in respect of which business of the Company or Related Company you: (i) had material responsibilities (including, without limitation, supervisory or management responsibilities) or carried out material duties; or (ii) otherwise obtained Relevant Confidential Information, in each case in the course of your employment.

“Key Person” means any employee, director, or consultant engaged by the Company or any Related Company who provides or has provided executive, managerial, supervisory, financial, engineering, creative, professional, technical, account handling, or similar services to the Company or any Related Company (a) with whom you have had material dealings; or (b) in respect of whom you have obtained Relevant Confidential Information about their skills, role, responsibilities, expertise, or other Relevant Confidential Information or material nonpublic information relevant to their potential recruitment or engagement, in each case at any time during the course of your employment.

“Relevant Confidential Information” means information not generally known outside the Company or any Related Company or information entrusted to the Company or any Related Company by third parties, which may relate (by way of example and without limitation) to inventions, formulas, patterns, devices, methods, processes, computer technology and programming, research, development, engineering, manufacturing, purchasing, accounting, marketing, or selling, and may be contained (by way of example and without limitation) in materials such as drawings, models, data, specifications, records, reports, complications, or computer programs, and may be in the nature of unwritten knowledge or know-how, in each case, that may or would be of value to any business which competes or is preparing to compete with the Company or a Related Company.

“Restricted Period” means the period ending on the earlier of: (a) the second anniversary of the later of the Vesting Date or the payment date for the Award; or (b) the six month anniversary of your termination of employment.

“Restricted Territory” means: (a) the United Kingdom; or (b) any other country where the Company or a Related Company carries out business and in relation to which you have had material responsibilities (including, without limitation, supervisory or management responsibilities) or carried out material duties during the course of your employment; or (c) any other country where the Company or a Related Company carries out business and in relation to which you acquired Relevant Confidential Information during the course of your employment.

2. Income Tax and Social Insurance Contribution Withholding. The following provision shall replace Section 11 of this Notice:

Without limitation to Section 11 of this Notice, you agree that you are liable for all Tax-Related Items and hereby covenants to pay all such Tax-Related Items, as and when requested by the Company, the Employer or by HM Revenue and Customs (“HMRC”) (or any other tax authority or any other relevant authority). You also agree to indemnify and keep indemnified the Company and the Employer against any Tax-Related Items that they are required to pay or withhold or have paid or will pay on your behalf to HMRC (or any other tax authority or any other relevant authority).

Notwithstanding the foregoing, if you are a director or executive officer (as within the meaning of Section 13(k) of the U.S. Securities Exchange Act of 1934, as amended), the terms of the immediately foregoing provision will not apply. In the event that you are a director or executive officer and income tax due is not collected from or paid by you within ninety (90) days after the U.K. tax year in which an event giving rise to the indemnification described above occurs, the amount of any uncollected tax may constitute a benefit to you on which additional income tax and national insurance contributions may be payable. You acknowledge that you ultimately will be responsible for reporting and paying any income tax due on this additional benefit directly to HMRC under the self-assessment regime and for reimbursing the Company or the Employer (as applicable) for the value of any employee national insurance contributions due on this additional benefit, which the Company and/or the Employer may recover from you at any time thereafter by any of the means referred to in Section 11 of this Notice.

3. Exclusion of Claim. You acknowledge and agree that you shall have no entitlement to compensation or damages in consequence of the termination of your employment with the Company or any Related Company for any reason whatsoever and whether or not in breach of contract, insofar as such entitlement arises or may arise from your ceasing to have rights under or to be entitled to vesting in your PRSUs as a result of such termination, or from the loss or diminution in value of your PRSUs. Upon the grant of your PRSUs, you shall be deemed irrevocably to have waived any such entitlement.

4. Brexit. With the United Kingdom no longer part of the European Union following the United Kingdom’s withdrawal from the European Union, the laws discussed herein regarding the European Union still apply to the United Kingdom and all references to the European Union shall include the United Kingdom, unless otherwise stated in this document.

I acknowledge that I have read and understand this Notice, the Addendum, and the Plan, and I accept and agree to the provisions contained therein.
