Amendment 39, dated December 21, 2023, to Special Business Provisions BCA-MS ###-###-####, dated June 16, 2005, between The Boeing Company and Spirit AeroSystems, Inc

THIS AMENDMENT NUMBER 39 (Amendment) to Special Business Provisions BCA-MS ###-###-#### is entered into as of the last dated signature below between Spirit AeroSystems, Inc., a Delaware corporation with its principal office in Wichita, Kansas (Spirit) and The Boeing Company, a Delaware corporation, acting by and through its Boeing Commercial Airplanes division (Boeing). Hereinafter, Spirit and Boeing may be referred to individually as a “Party” and jointly as the “Parties.”

A.The Parties have entered into the Special Business Provisions, BCA-MS ###-###-####, dated June 16, 2005 (SBP) and the General Terms Agreement, GTA BCA ###-###-####, dated June 16, 2005 (collectively, the Agreement).

B.The most recent amendment to the SBP is Amendment 38, entered into on July 10, 2023.

C.The Parties entered into a Memorandum of Agreement dated October 12, 2023 (MOA).

D.All capitalized terms used but not defined in this Amendment have the same meaning as in the SBP.

E.The Parties wish to amend the SBP as set forth herein.

NOW, THEREFORE, the Parties agree as follows:

1.The list of “AMENDMENTS” within the SBP is hereby deleted and replaced in its entirety as follows:

2.SBP Section 3.2.1 is deleted and replaced in its entirety with the following:

This SBP contains no minimum or maximum production rates.

A.Spirit will implement a production rate of [****] Shipsets per month eighteen (18) months from when Boeing directs such a production rate increase in writing. Boeing will accelerate deliveries of Boeing Furnished Material, also referred to as Partner Managed Inventory (“PMI”), as reasonably necessary to support Spirit’s start of [****] Shipsets per month.

B.Spirit is responsible for capitalization to support a production rate of [****] Shipsets per month as described below.

Boeing will advance to Spirit up to $[****] for Spirit’s implementation of Tooling and capital expenditures necessary to support up to [****] Shipsets per month. Boeing will pay to Spirit, via purchase order (issued no later than 60 days prior to the respective payment date, unless otherwise specified below) and invoice, for Tooling and capital expenditures by Spirit, as follows:

ii. Spirit agrees to prioritize purchased assets to Boeing production requirements, provide Boeing with documentation validating expenditures,

and provide Boeing on-site representatives with observable evidence of assets in place on a periodic basis.

Spirit will repay to Boeing up to $[****], as further specified below. Spirit will align the repayment plan to coincide with Spirit’s deliveries to Boeing and will offset payments utilizing the formula of number of units delivered in the respective time period based on the schedule below, times average shipset price, until the amount is fully offset for each respective time period. Any variability to this calculation based on the offset of units, or average shipset price, will be trued up in the fourth quarter of 2027. Spirit will repay to Boeing, via wire transfer, up to $[****], as follows:

$[****] paid no later than April 30, 2025

$[****] paid no later than October 31, 2025

$[****] paid no later than April 30, 2026

$[****] paid no later than October 31, 2026

$[****] paid no later than April 30, 2027

$[****] paid no later than October 31, 2027

In the event that Boeing advances to Spirit less than $[****], the repayment amount of $[****], and the individual repayment amounts above, will be proportionately adjusted so that Spirit’s total repayment is equal to 79.0518% of Boeing’s advance. This percentage represents the initial repayment amount over the initial advance amount.

C.For the first occurrence exceeding [****] Shipsets per month, Spirit acknowledges that production rates can be reached within a commercially reasonable lead time. Boeing will provide market and backlog data to Spirit prior to Boeing’s decision to increase the production rate and to assist the Parties in determining Spirit’s overall business case.

At the time of the Boeing decision to increase the production rate above [****] Shipsets per month, if Spirit requires capital investments to attain the desired rate, a contribution margin calculation as specified in SBP Attachment 28 shall be utilized to determine if the additional revenue will reasonably recover Spirit’s estimate of its capital investments. In the event this calculation does not project recovery of Spirit’s investments, then Boeing and Spirit will negotiate an equitable price adjustment.

D.Spares requirements are in addition to production. Spirit shall support all Spares. (For capacity planning purposes only, a reasonable estimate at the time of execution of this SBP is an average of .25 Shipsets per month.)

E.For the avoidance of doubt, nothing in this SBP Section 3.2.1 shall affect the provisions of SBP Section 3.3.7 and Attachment 23, “Derivatives and Mission Improvement.”

3.A new SBP Section 4.1.4 is added:

“4.1.4 Shipset Prices for Shipsets 1164 through 1605 and Shipsets 1606 and Beyond

As of Amendment 39, Boeing will pay Spirit $[****] via incremental 787 recurring Shipset Price increases effective at LN 1164 through LN 1605. The per Shipset Price shall be rate variable and as set forth in Attachment 1, Recurring Shipset Price (All Minor Models). No later than 10 business days after execution of Amendment 39, Boeing will amend any outstanding purchase orders as necessary to reflect the pricing shown in Attachment 1, Recurring Shipset Price (All Minor Models). No later than 15 business days after execution of Amendment 39, the Parties will jointly reconcile pricing for any Products already delivered starting with Line Number 1164 through such time as the purchase orders are amended with pricing as shown in Attachment 1, Recurring Shipset Price (All Minor Models). No later than 3 business days after the Parties complete the reconciliation, Boeing will pay to Spirit the reconciliation value via wire transfer.

Within 30 days following the delivery of Line Number 1605 from Spirit to Boeing, the Parties will reconcile the adjusted pricing set forth in Attachment 1, Recurring Shipset Price (All Minor Models) against the 787 Shipset pricing as of 787 SBP Amendment 37. In the event the incremental amounts paid to Spirit do not total $[****], the respective Party will pay, via wire transfer, any amount due within 10 business days of completing the reconciliation. For clarity, any Shipset pricing revisions subsequent to Amendment 39 resulting from statement of work revisions/changes will not be applied towards the $[****] incremental Shipset Price increase.

The Parties, at either’s request, agree to meet at a mutually agreeable time, with a mutual goal of concluding negotiations 12 months prior to the delivery of LN 1605, to discuss in good faith potential pricing changes, other interests and considerations pertaining to LN 1606 and beyond.”

4.SBP Section 4.3.1 is deleted and replaced in its entirety with the following:

Boeing and Spirit will develop a firm fixed average Price for each Spare Part, in which the Price shall be the "indentured" prices of parts as specified in SBP

Attachment 7 and the application of pricing factors as provided in SBP Section 4.3.4, “Spares Pricing Factors”. The result shall be incorporated into the Spares Parts Price Catalog (SPPC) as described in SBP Section 3.5. The line item prices contained in such "indentured" priced parts list (“IPPL”) shall be adjusted by Spirit, and agreed to by Boeing, each time an adjustment of Prices for Products is made pursuant to SBP Section 7.0 “Change Provisions”, with the effect that the sum of such line item prices shall equal the then current average Shipset Price. Spirit shall update the SPPC to reflect then current pricing not later than ninety (90) days after completion of any amendment of this SBP as provided in SBP Section 7.0 and the Administrative Agreement. Payment for any Spare Part will be made in accordance with SBP Section 5.0 “Payment”. Separate Indentured Parts Price Lists shall be established for the 787-8 and any derivative configuration.

Notwithstanding anything to the contrary in this SBP, the IPPL and SPPC will not be adjusted to reflect the $[****] of incremental 787 recurring Shipset Price increases made pursuant to the Parties’ MOA dated October 12, 2023.”

5.SBP Attachment 1 is deleted and replaced in its entirety with the following:

As of Amendment 39, Boeing will pay Spirit $[****] via incremental 787 recurring Shipset Price increases effective at LN 1164 through LN 1605. The per Shipset Price shall be rate variable and as set forth in Attachment 1, Recurring Shipset Price (All Minor Models). No later than 10 business days after execution of Amendment 39, Boeing will amend any outstanding purchase orders as necessary to reflect the pricing shown in Attachment 1, Recurring Shipset Price (All Minor Models). No later than 15 business days after execution of Amendment 39, the Parties will jointly reconcile pricing for any Products already delivered starting with Line Number 1164 through such time as the purchase orders are amended with pricing as shown in Attachment 1, Recurring Shipset Price (All Minor Models). No later than 3 business days after the Parties complete the reconciliation, Boeing will pay to Spirit the reconciliation value via wire transfer.

Within 30 days following the delivery of Line Number 1605 from Spirit to Boeing, the Parties will reconcile the adjusted pricing set forth in Attachment 1, Recurring Shipset Price (All Minor Models) against the 787 Shipset pricing as of 787 SBP Amendment 37. In the event the incremental amounts paid to Spirit do not total $[****], the respective Party will pay, via wire transfer, any amount due within 10 business days of completing the reconciliation. For clarity, any Shipset pricing revisions subsequent to Amendment 39 resulting from statement of work revisions/changes will not be applied towards the $[****] incremental Shipset Price increase.

The Parties, at either’s request, agree to meet at a mutually agreeable time, with a mutual goal of concluding negotiations 12 months prior to the delivery of LN 1605, to discuss in good faith potential pricing changes, other interests and considerations pertaining to LN 1606 and beyond.
