ARLINGTON, Virginia — Boeing’s Commercial Airplanes division posted a US$697m operating loss in the third quarter of 2026, even as the company generated US$464m in free cash flow, a measure outside generally accepted accounting principles (non-GAAP), according to its October 27 results release.
The commercial business reported a negative operating margin of 6.5% on revenue of US$10.72bn. Boeing attributed its performance primarily to a less favorable delivery mix, higher projected costs associated with future production-rate adjustments and higher estimated supply-chain costs.
Commercial deliveries barely changed from a year earlier, at 161 aircraft compared with 160, while divisional revenue fell 3%. The delivery total masks the less favorable aircraft mix and higher costs Boeing cited.
Boeing’s cash-flow table reconciles US$1.496bn in operating cash flow with US$1.032bn in spending on property, plant and equipment, leaving US$464m in free cash flow. That compared with US$238m a year earlier.
The quarterly improvement did not bring the first nine months into positive territory. Free cash flow for that period was negative US$359m, compared with negative US$2.252bn in the same period of 2025.
Boeing said working-capital timing contributed to quarterly operating cash flow, partly offset by approximately US$700m in Department of Justice settlement payments. Capital spending reflected higher investment at its Charleston and St. Louis sites.
The group cash figure covers all Boeing businesses and measures operating cash after capital spending; the Commercial Airplanes result measures the division’s operating earnings. Positive consolidated free cash flow therefore does not establish that commercial-airplane production was profitable.
Other divisions reported operating profits: US$492m at Defense, Space & Security and US$1.019bn at Global Services. The defense result included a US$252m gain from the sale of HRL Laboratories. Boeing as a whole recorded a US$116m net loss on revenue of US$24.188bn.
Boeing said the 737 program was progressing toward stabilized production of 47 aircraft per month, while 787 production was stable at eight per month. The 737 figure describes a production objective still being worked toward, following the rate transition covered in Airways’ second-quarter results report.
Commercial Airplanes’ operating loss narrowed from US$5.353bn a year earlier, when results were affected by a 777X charge.
Boeing also retained its expectation of a first 777-9 delivery in 2027, with certification flight testing continuing.
