Boeing makes money three ways: it builds commercial passenger jets like the 737 and 787 and sells them to airlines around the world; it builds military aircraft, missiles, and satellites for governments; and it provides maintenance, parts, training, and upgrades to both commercial and defense customers through its Global Services division. Airlines pay billions of dollars per plane, so revenue swings dramatically depending on how many jets Boeing can actually deliver in a given year. In 2025, Boeing delivered 600 commercial aircraft, up sharply from 348 in 2024, and total revenue jumped to $89.5 billion from $66.5 billion the year before. The diagram below traces where the money goes.

Five years of financial data tell a story of a company that has been burning cash, losing money on its core products, and fighting to stabilize. In 2021, Boeing generated $62.3 billion in revenue but was still spending more than it took in, with free cash flow negative $4.4 billion. Things improved through 2022 and 2023, when deliveries climbed and free cash flow turned positive, reaching $4.4 billion in 2023. Then 2024 hit hard.
2024
crisis
A door plug, a strike, and a $14 billion cash drain
In January 2024, a door plug blew out of a 737 to 9 mid-flight. The FAA restricted 737 production rate increases and tightened oversight. Then in September 2024, roughly 30,000 factory workers went on strike for 53 days, halting production of the 737, 767, 777, and 787. Boeing lost $11.8 billion for the year, burned $14.3 billion in free cash flow, cut 17,000 jobs, and raised nearly $19 billion by selling new shares to stay solvent.
The 2024 crisis made the 2025 recovery look dramatic on paper. Revenue surged to $89.5 billion, the highest in this five-year window, and Boeing posted its first net profit since 2023, at $2.235 billion. But the recovery is less clean than the headline suggests. The Commercial Airplanes division still lost $7.1 billion from operations in 2025. The Defense division lost $128 million. The only segment that made real money was Global Services, and a large chunk of that came from selling the Digital Aviation Solutions business for $10.55 billion, a one-time event. Strip that out, and the picture is much more mixed.
Boeing Free Cash Flow (2021 to 2025, $B)
Free cash flow turned positive in 2022 and 2023, collapsed in 2024 during the door plug crisis and labor strike, and remained negative in 2025 despite the revenue recovery.
The debt load reflects years of burning cash. Net debt stood at $50 billion in 2021, improved to $39.6 billion by 2023, then climbed back to $43.2 billion by end of 2025. Boeing is paying $2.771 billion per year in interest and debt expense. That is money that cannot go toward fixing factories, developing new planes, or rebuilding financial cushion.
$682B
Total order backlog at end of 2025, up from $521B at end of 2024
The backlog number is genuinely large. Airlines and governments have placed orders worth $682 billion that Boeing has not yet fulfilled. That represents years of future revenue, assuming Boeing can actually build and deliver the planes. The problem is that Boeing has repeatedly struggled to turn its order book into cash. Certification delays, production problems, and labor disruptions have all caused deliveries to fall short of plan.
What is a reach-forward loss?
When Boeing estimates the total cost to complete a program and that estimate exceeds the total revenue it expects to receive, it records a reach-forward loss immediately. This means Boeing can report a loss on a program years before it finishes building the planes. It is a signal that a program is in financial trouble.
The 777X, Boeing's newest wide-body jet, has recorded $4.9 billion in losses in 2025 alone. The program has faced certification delay after delay, and first delivery of the 777 to 9 has been pushed back again. The 737 to 7 and 737 to 10, two smaller variants of the 737, are still awaiting FAA certification and Boeing expects that to happen in 2026. Until those planes are certified and deliveries begin, Boeing cannot book revenue from them. Combined reach-forward losses on the 777X and 767 programs totaled $5.283 billion in 2025.

Combined reach-forward losses on the 777X and 767 programs recorded in 2025
On the defense side, roughly 60 percent of Boeing's defense revenue comes from fixed-price contracts. That means if costs run over budget, Boeing absorbs the loss, not the government. In 2024, Boeing recorded $5 billion in additional losses across five major defense programs because of cost estimation errors and technical problems. The 2025 defense loss was much smaller at $128 million, but the structural risk of fixed-price contracts does not go away.
What is a fixed-price contract?
On a fixed-price contract, the customer agrees to pay a set amount no matter what it actually costs to do the work. If Boeing's costs rise because of supply chain problems, labor issues, or engineering challenges, Boeing pays the difference out of its own pocket. This is the opposite of a cost-plus contract, where the government reimburses actual costs.
Labor is another ongoing pressure. About 40 percent of Boeing's 182,000 employees belong to unions. In 2024, the IAM District 751 strike lasted 53 days. In 2025, the IAM District 837 strike lasted 101 days, disrupting defense programs in St. Louis including the F/A-18 and F-15. Key engineering union contracts covering roughly 16,000 employees are set to expire in October 2026, creating another potential point of disruption. Boeing also faces supply chain strain, with suppliers dealing with inflation, labor problems of their own, and the added pressure of tariffs on aluminum, titanium, and other materials.
China is a significant market for Boeing, representing about 85 percent of BCA's backlog by dollar value being with non-U.S. airlines. In 2025, some Chinese customers temporarily paused accepting deliveries during tariff negotiations. A May 2026 meeting between U.S. and Chinese leaders produced a commitment for China to purchase 200 Boeing planes, but U.S.-China trade relations remain an ongoing watch item with the tariff pause extending only through November 2026.

Commercial Airplanes revenue 2024
$41.5B
Commercial Airplanes revenue 2025
BCA revenue nearly doubled in one year as deliveries recovered from the strike and door plug crisis. But the division still lost $7.1 billion from operations in 2025.
That gap between rising revenue and persistent operating losses is the central tension in Boeing's financial story. The company is delivering more planes. Costs are not yet under control. The 777X and new 737 variants are not certified. Defense programs carry ongoing fixed-price risk. And $43.2 billion in net debt means the margin for error is thin.
The Bet
Boeing's Commercial Airplanes division has to become consistently profitable at scale before the company can repair its balance sheet and fund the programs it needs to stay competitive. That requires the 737 production rate to keep rising toward 47 per month and beyond with FAA concurrence, the 777X to finally receive certification and begin generating revenue, and the 737 to 7 and 737 to 10 to be certified in 2026 as expected. If any of those milestones slip again, whether due to FAA delays, supply chain failures, or another labor disruption, the division that accounts for 46 percent of total revenue stays in loss, debt stays elevated, and the recovery story stalls.
Open question
Boeing has a $682 billion backlog, a recovering delivery rate, and airlines that need new planes badly. But it has now posted operating losses in its Commercial Airplanes division for three straight years, the 777X has burned through billions without a single delivery, and another major union contract expires in late 2026. Can Boeing actually convert its enormous order book into profitable deliveries before another production disruption, certification failure, or cost overrun resets the clock again?
Compiled · 10-K · FY2025
Production and Certification Delays
Boeing's new aircraft programs like the 777X, 737 to 7, and 737 to 10 have experienced significant delays in getting approval from the FAA. The 777X program alone has recorded $4.9 billion in losses in 2025 due to production challenges, certification delays, and higher labor and supplier costs, and customers have the right to cancel orders or demand compensation for late deliveries.
Union Labor Disruptions
About 40% of Boeing's workforce (72,000 employees) are represented by labor unions. In 2024, a 53-day strike by machinists in Washington halted production of most commercial aircraft, and in 2025, another 101-day strike disrupted St. Louis operations affecting defense programs. Future strikes or failure to negotiate new contracts could materially harm Boeing's ability to deliver products and generate revenue.
Supply Chain and Supplier Costs
Boeing depends on many suppliers for materials like aluminum, titanium, and composites, and these suppliers are facing cost pressures, labor instability, and production delays. If suppliers cannot deliver components on time and at budgeted costs, or if raw materials become unavailable or too expensive due to tariffs, Boeing may be unable to meet customer delivery commitments and maintain profitability.
Defense Spending and Government Appropriations
About 35% of Boeing's revenue comes from U.S. government contracts, primarily defense programs. Delays in Congressional appropriations, spending caps, or shifts in defense priorities could reduce funding for Boeing programs, delay payments to Boeing, or require furloughs of government employees who oversee Boeing's work, harming the company's ability to deliver and generate revenue.
Fixed-Price Defense Contracts
Approximately 60% of Boeing's defense business revenue comes from fixed-price contracts where Boeing bears the risk of cost overruns. In 2024, Boeing recorded $5 billion in additional losses on five major defense programs due to cost estimation errors and technical challenges, which directly reduces profitability and future cash available for other needs.
