Boeing’s Q3 2026 results, published on 27 October 2026, confirmed that 737 production will not be stable at 47 a month until early 2027, against a target of this summer as recently as May. Boeing now guides FCF (operating cash flow less capital spending) of about $3bn for 2027, against an LSEG consensus of $5.5bn, and puts its $10bn target in 2029. For airlines and lessors waiting on new aircraft, this means later deliveries and firmer demand for the current fleet.

The shares fell 9.6% to $170.23 in afternoon trading on the day, according to Reuters. Below we set out what Boeing reported, what management said on the call, and what we think it means. We mark fact and inference separately and give a confidence level for each view.

Boeing’s Q3 2026 results in brief

The figures below come from Boeing’s release of 27 October 2026.

MeasureQ3 2026Q3 2025
Revenue$24.188bn$23.270bn
GAAP net loss$116m$5,339m
GAAP loss per share$0.26$7.14
Core loss per share (non-GAAP)$0.34$7.47

Capital spending$1,032m$885m
FCF (non-GAAP)$464m$238m
Commercial deliveries161160

LSEG consensus, as reported by Reuters, was a core loss of 21 cents a share. Operating cash flow absorbed about $0.7bn of Department of Justice settlement payments. Over 9 months, FCF was negative $359m.

Cash and marketable securities were $20.7bn at 30 September, with consolidated debt of $45.9bn and $10bn of undrawn credit facilities. Total backlog reached a record $745bn. Commercial Airplanes accounted for $612bn of that, covering more than 6,300 aircraft, after 300 net orders in the quarter from customers including Turkish Airlines, Ethiopian Airlines and Lufthansa.

The quarter’s 161 deliveries comprised 124 737s, 22 787s, 10 767s and 5 777s. The 737-7 gained FAA amended type certification in the quarter and the 737-10 followed in October.

Why 737 production has slowed

The main constraint is wing production. Chief executive Kelly Ortberg told analysts that final assembly is performing well, with rework down 40% since the start of 2025, but that it is “taking us longer than we had expected to demonstrate performance at rate 47”. He expects it “will take us into next year to get fully stable at this rate”.

Reaching 52 a month, now targeted for the second half of 2027, needs 3 things to happen together. The new North Line at Everett, Washington, has to be certified and producing. The back shops, including wings, have to be stable. Fuselage output at the former Spirit AeroSystems plant in Wichita, Kansas, has to hold at the higher rate. Management also said it expects longer gaps between rate steps as rates rise.

For 2026, Boeing said the delay will leave 737 deliveries short of its 500 target. Aircraft built before the 737-7 and 737-10 were certified start delivering early next year.

The 787 and 777X programmes

The 787 is stable at 8 a month. Boeing still expects 90 to 100 deliveries this year but closer to the lower end, because rate 10 is late. Ortberg said seat certification has made monthly delivery cadence uneven and that engine deliveries remain the pacing item for rate 10. With 62 787s delivered in the first 9 months, the low end needs 28 in the fourth quarter.

The 777-9 is still in certification flight testing and needs approval to begin the rest of the programme, including ETOPS testing. First delivery is still expected in 2027. Production is at about 1 a month and is expected to stay there for most of 2027.

Chief financial officer Jay Malave said a wing component supplier disrupted the 777 Freighter and 767 lines during the quarter, with the effect running through production over several quarters. Reuters reported on 23 October, citing 3 Boeing workers and court filings, that a dispute with sole supplier Vaero over trailing-edge rib kits had halted 777F production for nearly 2 months. Boeing declined to comment to Reuters. The duration comes from unnamed sources, and Boeing has not confirmed it.

The new cash flow path

Boeing guided FCF of about $2bn for 2026, about $3bn for 2027, about $6bn for 2028 and $10bn for 2029. Malave linked the 2027 figure to lower year-on-year commercial order deposits and about $1bn of extra capital spending, including new defence work. Capital spending is guided at about $5bn in 2027, then about $4bn a year in 2028 and 2029. The 2029 target assumes 737 output of 52 to 58 a month and 787 output of 12 a month.

Reuters, citing LSEG, said the $10bn arrives a year later than the market had assumed. Jefferies put 2027 consensus at $5.5bn.

What the delay means for airlines and lessors

Fact. Boeing’s commercial backlog covers more than 6,300 aircraft and is still growing. On 27 October, shareholders of Bohai Leasing approved Avolon’s purchase of 140 737 MAX and 110 Airbus aircraft. Securities Daily reported Bohai’s results announcement. Avolon had said that approval was the only remaining condition. Bohai’s filing says the 737 MAX deliveries run to the end of 2036.

Inference, high confidence. Airlines with 737 MAX slots in 2026 and 2027 should plan for some to slip. A slower climb from 47 to 52 a month removes aircraft from the delivery schedule that cannot be recovered quickly, because Boeing says it will take longer between rate steps.

Inference, medium confidence. Scarce new deliveries support values and lease rates for current-generation narrowbodies and for mid-life 737NG and A320ceo aircraft that airlines keep flying for longer. We have no new market data from this week to size that effect, and we would not put a number on it yet. Lessors with near-term orderbook positions hold the most valuable slots. Lessors with sale-leaseback commitments tied to specific delivery months face the most timing risk.

Inference, medium confidence. On the 787, the issue is cadence. Seat certification and engine supply mean aircraft arrive in uneven batches, which complicates airline schedule planning more than it changes annual totals.

The effect on MRO demand

Older aircraft flying for longer need more heavy checks and more engine shop visits. That adds to pressure on a market already short of capacity, which we covered in The MRO Capacity Crisis.

The FAA’s proposed airworthiness directive on the CFM56-7B, the engine on the 737NG, adds to that load. Published in the Federal Register on 27 October 2026 (docket FAA-2026-11817), it covers every CFM56-7B model. It follows a 737-800 fan blade separation that caused an in-flight shutdown, debris penetrating the fuselage, loss of pressurisation and an emergency descent.

As proposed, installed engines would need a visual fan blade inspection within 400 flight cycles or 90 days of the effective date, whichever comes first, with findings reported to CFM. The FAA estimates 3,450 engines on the US register are affected and costs a replacement blade at $51,400. It calls the AD interim action while root-cause work continues. Comments close on 27 November 2026, a 30-day period shortened to align with EASA.

Inference, medium confidence. For lessors, the directive matters at lease return. Inspection findings and blade replacements will feed into return condition negotiations on 737NG aircraft over the next year.

Where could consensus still be wrong?

Inference, medium confidence. The 2027 cash figure matters more than the 2026 delivery miss. If wing output and Wichita fuselages both fall short at the same time, 52 a month in the second half of 2027 looks optimistic. The $10bn in 2029 then has little room for error, because it already assumes 737 rates of 52 to 58 and 787 rates of 12.

Inference, lower confidence. The market may be underestimating how long current-generation aircraft stay in demand. That favours owners of 737NG and A320ceo aircraft and the engine shops that support them.

What would change our view?

  • Boeing confirms stable 737 production at 47 a month in the first quarter of 2027.
  • The FAA approves the Everett North Line and it delivers about 5 a month.
  • 787 deliveries reach 28 or more in the fourth quarter of 2026.
  • Boeing’s 2026 FCF lands at or above $2bn.
  • The final CFM56-7B AD has a longer compliance window than proposed.

If most of these happen, the delay is shorter than we expect and the support for current-fleet values fades sooner.
