- The Boeing Company NYSE:BA faces a MAX 10 delivery gap at its largest airline customer.
- United Airlines Holdings, Inc. NASDAQ:UAL expects 147 of 167 jets after 2027.
- Boeing shares lost 7.5% last week as labor and certification risks converged.
Boeing’s largest 737 MAX 10 customer now expects 88% of its firm order after 2027. That delivery split makes certification timing a cash-flow issue, not just a regulatory milestone.
United’s latest filing shows 147 of 167 MAX 10 commitments arriving after 2027. Its contract had placed 120 aircraft in that later window. The difference is 27 jets.
| United MAX 10 deliveries | Contractual | Expected | Shift |
|---|---|---|---|
| Second half 2026 | 3 | 0 | -3 |
| 2027 | 44 | 20 | -24 |
| After 2027 | 120 | 147 | +27 |
| Total commitments | 167 | 167 | 0 |
The information gain is clearer in percentage terms. The post-2027 share rose to 88.0% from 71.9%, a 16.2-point shift. Investors therefore have less near-term delivery exposure than the headline order count suggests.
Boeing finished the MAX 10’s planned flight testing on July 28. The program logged 976 flights and more than 2,060 flight hours. Final development reviews and safety assessments still need completion before FAA approval.
| MAX 10 certification item | Reported progress | Investor read-through |
|---|---|---|
| Planned flight tests | 100% | Flying phase complete |
| Development assurance review 4 | 60% | 40% remains |
| System safety assessments | 32% | 68% remains |
| Certification target | 2026 | FAA review is the gate |
The stock has already repriced some execution risk. Boeing closed Friday at $214.20, down 7.54% from August 14. That erased about $13.8 billion of market value on a preliminary basis.
| Date | BA close | Daily move |
|---|---|---|
| Aug. 14 | $231.67 | +0.58% |
| Aug. 17 | $225.95 | -2.47% |
| Aug. 18 | $223.06 | -1.28% |
| Aug. 19 | $222.20 | -0.39% |
| Aug. 20 | $215.10 | -3.20% |
| Aug. 21 | $214.20 | -0.42% |
A new labor clock now overlaps the certification closeout. About 17,000 engineers and technical workers rejected Boeing’s contract offers on Friday. They also authorized union leaders to call a strike after contracts expire October 6.
“We have no choice but to implement our contingency plan,” Boeing vice president Ben Nimmergut said. Reuters reported no new talks were scheduled after the vote.
The operating recovery offers a counterweight. Second-quarter revenue rose 8% to $24.56 billion. Free cash flow reached $631 million, while backlog hit a record $715 billion.
| Analyst recommendation | August count | Share of 28 |
|---|---|---|
| Strong Buy | 18 | 64.3% |
| Buy | 5 | 17.9% |
| Hold | 5 | 17.9% |
| Sell / Strong Sell | 0 | 0.0% |
| Average target | $274.85 | 28.3% above Friday close |
Wall Street’s rating mix remains bullish. That optimism assumes certification unlocks deliveries, inventory and cash. United’s schedule shows much of that benefit now falls beyond the next 16 months.
U.S. markets were closed Sunday. The week ahead will test whether Boeing can restart labor talks and preserve its 2026 certification target. The FAA has not announced final MAX 10 approval.
Risks: United’s schedule can change, and certification may arrive without further delay. A labor agreement could remove the newest overhang. A strike or longer FAA review could push more deliveries beyond 2027.
