Boeing CEO Reports 737 MAX Output Stabilization Delays

Production Stability Challenges

Boeing CEO Kelly Ortberg stated on Wednesday that the company is experiencing delays in stabilizing Boeing 737 MAX production at the target rate of 47 aircraft per month. Speaking at the Morgan Stanley Laguna Conference, Ortberg noted that the ramp-up is taking "longer than expected," creating operational headwinds for the airframer. This development in the Boeing 737 MAX production line is critical to the company's financial recovery, as it currently carries nearly $26 billion in net debt.

Certification and Delivery Bottlenecks

While the Federal Aviation Administration (FAA) successfully certified the Boeing 737-7 earlier this year, the larger 737-10 certification timeline remains a focal point for the industry. The 737-10 accounts for approximately 30% of the total 737 order book, and Ortberg expressed confidence that certification would arrive "very soon." However, the wider Boeing 787 Dreamliner program continues to face significant pressure. Despite a current output of eight aircraft per month, plans to increase production to 10 per month are currently stalled due to engine supply shortages and slow regulatory certification of premium cabin seats.

Financial Outlook and Market Impact

Chief Financial Officer Jay Malave confirmed that the slower production ramps for both the 737 and 787 programs have forced a recalibration of the company's financial outlook. Boeing now expects to generate $2 billion in free cash flow—the midpoint of its guidance—rather than the $3 billion upside initially projected in January. Investors reacted to the updated guidance and production commentary, with the company's share price closing down 4.5% on the day of the announcement.

Aerospace Supply Chain Constraints

The current manufacturing environment reflects broader aerospace supply chain bottlenecks that have hindered major original equipment manufacturers. Historically, the Boeing 787 Dreamliner delivery halt from 2020 to 2022 serves as a precedent for the complexities of widebody production stability. Similar to the Airbus A320neo supply chain constraints observed between 2022 and 2024, Boeing is struggling to align its rate increases with the availability of critical components. The "lumpy" nature of 787 deliveries, as described by Ortberg, underscores the difficulty of maintaining consistent output when interior component certifications remain a gating factor.

Why the 737-10 Certification Matters

For 737 MAX 10 customers, such as major global carriers, the continued uncertainty regarding the certification timeline complicates long-term fleet modernization and capacity planning. The industry is watching closely to see if the 737-10 can bridge the gap between current narrowbody demand and the delivery delays that have plagued the industry for years. As Boeing works to resolve these production hurdles, the focus remains on whether the company can solidify its output rates to support its $2 billion cash flow target by the end of 2026.
