Boeing's 737-10 Certification Clears One Hurdle, but Market Still Demands More

What happened

FAA certified the 737-10 on or about October 20, 2026, removing a key regulatory hurdle for that variant and enabling deliveries to begin once Boeing completes required documentation and customer preparation. This certification was one of the explicit gates in Boeing's recovery plan and had been expected by year-end 2026; its early arrival is a positive signal but does not eliminate risks from the still-pending 737-7 certification and production-rate constraints. Despite this milestone, Boeing shares are down 14.99% since the second-quarter report on July 28, 2026, indicating investors are pricing in concerns about third-quarter financials, potential charges, or slower-than-expected free cash flow. The upcoming Q3 earnings on October 27 will provide clarity on production rates, backlog conversion, and whether the MAX 10 certification can translate into near-term delivery uplift given stored inventory and customer readiness. The company still faces meaningful overhangs, including the unresolved 737-7 certification, the 737 production cap, and legacy defense charges, so a single certification is necessary but not sufficient to confirm the recovery thesis.

Implication

The MAX 10 certification removes one of the two remaining certification overhangs for the 737 family, but until the MAX 7 is certified and production rates can rise, the revenue and cash flow impact is limited to the roughly 40 stored MAX 10 aircraft and future deliveries. The stock's 14.99% decline since the last report despite this milestone indicates that investors are likely more focused on near-term financial performance, including operating cash flow, defense charges, and 737 production stability than on certification headlines alone. For existing holders, the event does not change the fundamental wait-and-see stance; the stock remains unattractive at current levels until there is evidence of sustained positive free cash flow and debt reduction, which may take another few quarters. The upcoming earnings call will provide crucial data points: actual Q3 deliveries, any updates on the 737 production rate progression beyond 47/month, and whether the certification can accelerate customer acceptances and inventory monetization before year-end. Any confirmation of further production-rate increases or MAX 7 certification could shift the risk-reward more favorably, while fresh charges or a disappointing cash flow number would reinforce the bear case; therefore, we maintain a WAIT rating with an attractive entry below $210 and a trim above $255 as per the DeepValue master report.

Thesis delta

The certification of the 737-10 is a clear positive that partially de-risks the commercial recovery, as one of the two key regulatory milestones has been met earlier than expected. However, the thesis remains conditional on the MAX 7 certification and sustained production-rate increases, and the market's negative reaction to the stock since July suggests that near-term financial execution is overshadowing the long-term backlog conversion story. Therefore, our investment thesis is unchanged: wait for clearer evidence of cash flow inflection or a more attractive entry point before increasing exposure.
