Boeing CEO: 737 Max production taking 'a little bit longer' to stabilize than expected

Boeing CEO Kelly Ortberg said 737 MAX production stabilization is taking longer than expected, with wing output at Renton currently constraining production. Boeing is producing roughly 47 737 MAX aircraft monthly and expects to increase output in 2027, while certification of the larger MAX 10 model is expected "very soon." The update signals gradual recovery in Boeing's key commercial-aircraft program but underscores continuing manufacturing bottlenecks after years of safety and quality disruptions.

Analysis

The key investable issue is not the stated production run-rate but whether it converts into a sustained delivery cadence without incremental inventory rework, supplier expedites, or abnormal compensation to airlines. A wing bottleneck implies that incremental volume could be margin-dilutive initially: fixed-cost absorption improves, but overtime, quality inspections, and disrupted final assembly can defer the expected cash conversion. Reconcile monthly deliveries, customer acceptance, and working-capital movement against the disclosed build rate before underwriting a material free-cash-flow upgrade.

A credible narrowbody ramp would disproportionately improve GE Aerospace's LEAP aftermarket installed-base trajectory and Safran's engine delivery mix, while reducing the relative scarcity value supporting Airbus' A320neo-family pricing. The more immediate airline effect is mixed: Southwest (LUV), United (UAL), and Alaska Air (ALK) gain capacity flexibility only when aircraft are delivered and crews certified; until then, delayed aircraft preserve elevated used-aircraft lease rates and support lessors such as Air Lease (AL). The largest variant's certification would be strategically helpful for Boeing's orderbook defense, but its valuation benefit depends on delivery slots rather than the certification headline itself.

Consensus may overvalue a symbolic certification or a one-month production datapoint after a prolonged execution cycle. BA's multiple can expand on evidence that the factory system is stable, but any renewed quality intervention would have an asymmetric downside because the balance sheet still requires reliable cash generation to fund debt reduction. The next 1-3 months should be treated as an operational proof period; the 6-18 month opportunity is a cash-flow and deleveraging rerating only if delivery growth exceeds rework and customer-compensation costs.

Key Decisions for Investors

• Maintain BA as a conditional long rather than chase the headline: add only after two consecutive months in which 737 deliveries demonstrate a rising trend and management does not reduce free-cash-flow or delivery guidance. Target a 6-12 month rerating on credible cash conversion; exit on a renewed regulatory production restriction, a material delivery-guidance cut, or evidence that inventory/working capital is absorbing the ramp.
• Express the cleaner second-order upside through a 6-12 month long GE versus short XLI pair, sized modestly. GE captures engine OE and future service-annuity optionality from a durable narrowbody ramp, while the industrial short reduces broad cyclical beta; invalidate if aircraft delivery data fail to improve or LEAP supply constraints prevent engine shipments from matching airframe output.
• Watch LUV, UAL, and AL for delivery-schedule disclosures rather than buying on certification expectations. A confirmed acceleration in aircraft handovers is modestly positive for airline growth plans but can pressure unit revenue through added seats; it is more directly negative for used-aircraft scarcity and lease-rate support if Boeing delivery reliability becomes established.
• Treat any BA move driven solely by the largest-variant certification as a potential trim opportunity unless accompanied by firm customer delivery timing and unchanged margin/cash targets. Certification removes a commercial overhang, but does not itself resolve production-system economics or accelerate cash receipts.
