<FONT STYLE="white-space:nowrap">S-4&#8221;),</FONT> which the Commission declared effective at 4:00 p.m. Eastern Time on December&nbsp;20, 2024, by filing this post-effective Amendment No.&nbsp;1 on Form <FONT STYLE="white-space:nowrap">S-8</FONT>
(this &#8220;Post-Effective Amendment&#8221; and together with the Form <FONT STYLE="white-space:nowrap">S-4,</FONT> this &#8220;Registration Statement&#8221;). </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">The Company filed the Form <FONT STYLE="white-space:nowrap">S-4</FONT> in connection with the merger contemplated by the Agreement and Plan of Merger, dated
as of June&nbsp;30, 2024 (the &#8220;Merger Agreement&#8221;), by and among Boeing, Spirit AeroSystems Holdings, Inc. (&#8220;Spirit&#8221;) and Sphere Acquisition Corp., a wholly owned subsidiary of Boeing (&#8220;Merger Sub&#8221;), pursuant to
which, effective as of December 8, 2025, Merger Sub merged with and into Spirit, with Spirit surviving the merger and becoming a wholly owned subsidiary of Boeing (the &#8220;Merger&#8221;). </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">At the effective time of the Merger (the &#8220;Effective Time&#8221;), each share of Class&nbsp;A Common Stock, par value $0.01 per share, of Spirit
(&#8220;Spirit Common Stock&#8221;) that was issued and outstanding immediately prior to the Effective Time (other than shares of Spirit Common Stock owned by Spirit, Boeing or any of their respective wholly owned subsidiaries, in each case not held
on behalf of third parties) was automatically cancelled and converted into the right to receive 0.1955 shares of common stock, par value $5.00 per share, of Boeing (&#8220;Boeing Common Stock,&#8221; and such number of shares of Boeing Common Stock,
the &#8220;Per Share Merger Consideration&#8221;). </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">Pursuant to the terms of the Merger Agreement, at the Effective Time, certain outstanding Spirit

multiplying the total number of shares of Spirit Common Stock subject to such Spirit RSU immediately prior to the Effective Time by the Per Share Merger Consideration, and any accrued but unpaid dividend equivalents with respect to such Spirit RSU
were assumed and became an obligation with respect to the applicable Boeing Stock-Based RSU. For Spirit PSUs, the number of shares of Boeing Common Stock subject to each such Boeing Stock-Based RSU was determined by multiplying the total number of
shares of Spirit Common Stock subject to such Spirit PSU immediately prior to the Effective Time based on the attainment of the applicable performance metrics at the actual level of performance, determined as specified in the Merger Agreement,
multiplied by the Per Share Merger Consideration. Each such Boeing Stock-Based RSU is governed by the same terms and conditions (including vesting terms, but excluding performance conditions in the case of Spirit PSUs) as were applicable to such
Spirit RSU or Spirit PSU immediately prior to the Effective Time. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">Boeing hereby amends the Form <FONT STYLE="white-space:nowrap">S-4</FONT> by filing

Spirit PSUs, originally granted under the Plan, that were converted to Boeing Stock-Based RSUs in connection with closing of the Merger. All such shares were previously registered on the Form <FONT STYLE="white-space:nowrap">S-4</FONT> but will be
