Boeing slides 6% as FAA halts Max 10 cert, 31% of undelivered orders at risk
The FAA has halted certification of Boeing’s 737 Max 10, putting 31% of its undelivered orders at risk and sending the shares down 6%. The setback raises a direct timing and backlog question for Boeing’s largest single commercial-aircraft program.

The report links the regulatory action to 31% of Boeing’s undelivered orders, identifying a substantial portion of the backlog as exposed to the Max 10 certification timeline.
The Max 10 is Boeing’s largest variant in the 737 Max family and its certification status determines when affected orders can move toward delivery. A halt therefore touches the order book through potential delivery timing and through the aircraft customers are contracted or planning to receive, rather than through an immediate change to all Boeing deliveries.
The development sits against Boeing’s FY2025 financial base: revenue was $89.5B, up 34.5% year over year, with a 2.5% net margin and $2.48 diluted EPS. Those annual figures provide context for the company’s scale, but do not quantify the financial effect of the certification halt.
The central uncertainty is how long the FAA action lasts, what certification work remains, and whether affected customers accept delayed Max 10 deliveries or seek changes to their orders. The next useful markers are an FAA decision on resumed certification activity, Boeing’s customer-order updates, and the company’s next results for evidence of delivery or backlog changes.
The FAA halted Boeing’s 737 Max 10 certification, putting 31% of undelivered orders at risk.
The certification halt puts delivery timing for 31% of undelivered orders under pressure, while Boeing’s 2.5% net margin leaves limited room for a prolonged operational disruption. The $89.5B FY2025 revenue base and $2.48 diluted EPS show the scale of the company, but do not yet quantify the backlog effect; the next Boeing results and FAA action should determine whether the issue remains a timing problem or reaches reported deliveries.
A prompt FAA resumption of Max 10 certification, with Boeing preserving the affected orders and delivery schedule, would undercut the read.

Boeing’s FY2025 revenue reached $89.5B, and a temporary certification halt could leave the 31% of undelivered orders intact if the FAA resumes the process without cancellations.
The FAA halt directly exposes 31% of Boeing’s undelivered orders, and the company’s 2.5% net margin offers little cushion if delays extend into deliveries or trigger order changes.
