Key developments

Boeing’s cautious production outlook weighed on shares during the session. Reporting linked the decline to a slower ramp for its narrowbody aircraft and a free cash flow forecast below consensus. Management said stabilizing production was taking longer than expected, raising questions about how quickly certification milestones and defense wins will translate into financial results.

Cash and revenue beat expectations, with revenue growth supported by defense deliveries and services demand. Management also highlighted earlier aircraft certifications, major defense awards, a labor agreement avoiding disruption, and a record backlog as evidence of operational progress.
