CHICAGO, October 27, 2021 - The Boeing Company [NYSE: BA] reported third-quarter revenue of $15.3 billion, driven by higher commercial airplanes and services volume.GAAP loss per share of ($0.19) and core loss per share (non-GAAP)* of ($0.60) primarily reflects higher commercial volume (Table 1). Boeing recorded operating cash flow of ($0.3) billion.

"We are driving stability across our operations, investing in our future and positioning our teams to deliver for our customers as the market recovers," said Boeing President and Chief Executive Officer David Calhoun. "Commercial market demand continues to gain traction with broad-based vaccine distribution and border protocols beginning to open. Going forward, supply chain capacity and global trade will be key drivers of our industry and the broader economy's recovery. Our portfolio across commercial, defense, space and services is well positioned, and we're focused on improving performance, while advancing technologies and digital manufacturing capabilities to drive our next generation of products and a sustainable future."

Segment Results

Commercial Airplanes

Table 4. Commercial Airplanes	Third Quarter	Nine Months
(Dollars in Millions)	2021	2020	Change	2021	2020	Change
Commercial Airplanes Deliveries	85	28	204%	241	98	146%
Revenues	$4,459	$3,596	24%	$14,743	$11,434	29%

Operating Margin	(15.5)	%	(38.1)	%	NM	(13.7)	%	(54.2)	%	NM

Commercial Airplanes third-quarter revenue increased to $4.5 billion primarily driven by higher 737 deliveries, partially offset by lower 787 deliveries. Third-quarter operating margin improved to (15.5) percent primarily due to higher deliveries (Table 4).

Boeing is continuing to make progress on the global safe return to service of the 737 MAX. Since the FAA's approval to return the 737 MAX to operations in November 2020, Boeing has delivered more than 195 737 MAX aircraft and airlines have returned more than 200 previously grounded airplanes to service. 31 airlines are now operating the 737 MAX, safely flying over 206,000 revenue flights totaling more than 500,000 flight hours (as of October 24, 2021). The 737 program is currently producing at a rate of 19 per month and continues to progress towards a production rate of 31 per month in early 2022, and the company is evaluating the timing of further rate increases.

The company continues to focus 787 production resources on conducting inspections and rework and continues to engage in detailed discussions with the FAA regarding required actions for resuming delivery. The current 787 production rate is approximately two airplanes per month. The company expects to continue at this rate until deliveries resume and then return to five per month over time. The low production rates and rework are expected to result in approximately $1 billion of abnormal costs, of which $183 million was recorded in the quarter.

Commercial Airplanes secured orders for 70 737 MAX, 24 freighter, and 12 787 airplanes. Commercial Airplanes delivered 85 airplanes during the quarter and backlog included over 4,100 airplanes valued at $290 billion.

Defense, Space & Security

Table 5. Defense, Space & Security	Third Quarter	Nine Months
(Dollars in Millions)	2021	2020	Change	2021	2020	Change
Revenues	$6,617	$6,848	(3)%	$20,678	$19,478	6%
Earnings from Operations	$436	$628	(31)%	$1,799	$1,037	73%
Operating Margin	6.6	%	9.2	%	(28)%	8.7	%	5.3	%	64%

Defense, Space & Security third-quarter revenue decreased to $6.6 billion and third-quarter operating margin decreased to 6.6 percent, primarily due to a $185 million earnings charge on the Commercial Crew program driven by the second uncrewed Orbital Flight Test now anticipated in 2022 and the latest assessment of remaining work.

During the quarter, Defense, Space & Security secured awards for five P-8A Poseidon aircraft for the German Navy and four CH-47F Block II Chinook helicopters for the U.S Army, as well as a Joint Direct Attack Munition contract for the U.S. Air Force. Defense, Space & Security also conducted the MQ-25 unmanned aerial refueling of a U.S. Navy E-2D and F-35C,and delivered a total of 37 aircraft during the quarter, including the first CH-47F Chinook to the Royal Australian Army.

Backlog at Defense, Space & Security was $58 billion, of which 33 percent represents orders from customers outside the U.S.

Global Services

Table 6. Global Services	Third Quarter	Nine Months
(Dollars in Millions)	2021	2020	Change	2021	2020	Change
Revenues	$4,221	$3,694	14%	$12,037	$11,810	2%

Operating Margin	15.3	%	7.3	%	110%	13.4	%	2.6	%	415%

Global Services third-quarter revenue increased to $4.2 billion and third-quarter operating margin increased to 15.3 percent primarily driven by higher commercial services volume.Operating margin was also favorably impacted by lower severance costs and mix of products and services.

During the quarter, Global Services captured orders for 12 additional 737-800 converted freighters for BBAM, an award for performance-based logistics support of the global C-17 fleet, and a modification award for Chinook infra-red suppression systems for the U.K. Armed Forces. Global Services also announced a partnership to expand capacity for 767-300 Boeing Converted Freighters and was selected to provide training to the United Aviate Academy.

Effective tax rate	57.4	%	49.6	%	62.2	%	40.1	%

At quarter-end, Boeing Capital's net portfolio balance was $1.8 billion. The earnings from FAS/CAS service cost adjustment primarily reflects an increase in the CAS discount rate driven by pension relief provisions in the American Rescue Plan Act of 2021. Interest and debt expense increased due to higher debt balances. The change in other income was driven by a pension settlement charge recorded during the quarter. The third quarter 2021 effective tax rate primarily reflects a lower pre-tax loss compared to the prior period, as well as benefits from R&D tax credits.

Non-GAAP Measures Disclosures

We supplement the reporting of our financial information determined under Generally Accepted Accounting Principles in the United States of America (GAAP) with certain non-GAAP financial information. The non-GAAP financial information presented excludes certain significant items that may not be indicative of, or are unrelated to, results from our ongoing business operations. We believe that these non-GAAP measures provide investors with additional insight into the company's ongoing business performance. These non-GAAP measures should not be considered in isolation or as a substitute for the related GAAP measures, and other companies may define such measures differently. We encourage investors to review our financial statements and publicly-filed reports in their entirety and not to rely on any single financial measure. The following definitions are provided:

Core Operating Earnings, Core Operating Margin and Core Earnings Per Share

Core operating earnings is defined as GAAP earnings from operations excluding the FAS/CAS service cost adjustment. The FAS/CAS service cost adjustment represents the difference between the Financial Accounting Standards (FAS) pension and postretirement service costs calculated under GAAP and costs allocated to the business segments. Core operating margin is defined as core operating earnings expressed as a percentage of revenue. Core earnings per share is defined as GAAP diluted earnings per share excluding the net earnings per share impact of the FAS/CAS service cost adjustment and Non-operating pension and postretirement expenses. Non-operating pension and postretirement expenses represent the components of net periodic benefit costs other than service cost. Pension costs, comprising service and prior service costs computed in accordance with GAAP are allocated to Commercial Airplanes and BGS businesses supporting commercial customers. Pension costs allocated to BDS and BGS businesses supporting government customers are computed in accordance with U.S. Government Cost Accounting Standards (CAS), which employ different actuarial assumptions and accounting conventions than GAAP. CAS costs are allocable to government contracts. Other postretirement benefit costs are allocated to all business segments based on CAS, which is generally based on benefits paid. Management uses core operating earnings, core operating margin and core earnings per share for purposes of evaluating and forecasting underlying business performance. Management believes these core earnings measures provide investors additional insights into operational performance as they exclude non-service pension and post-retirement costs, which primarily represent costs driven by market factors and costs not allocable to government contracts. A reconciliation between the GAAP and non-GAAP measures is provided on pages 13-14.

Free Cash Flow

Free cash flow is GAAP operating cash flow reduced by capital expenditures for property, plant and equipment. Management believes free cash flow provides investors with an important perspective on the cash available for shareholders, debt repayment, and acquisitions after making the capital investments required to support ongoing business operations and long term value creation. Free cash flow does not represent the residual cash flow available for discretionary expenditures as it excludes certain mandatory expenditures such as repayment of maturing debt. Management uses free cash flow as a measure to assess both business performance and overall liquidity. Table 2 provides a reconciliation of free cash flow to GAAP operating cash flow.
