TLDRs;
- FAA advances MAX 10 testing, but engine deicing issues remain unresolved.
- Investors watch MAX 10 timeline as backlog conversion drives revenue potential.
- Market reacts to certification progress; delays could weigh on Boeing stock.
- Q4 earnings on January 27 expected to influence delivery expectations.
Boeing (BA) shares climbed 3.1% on Friday, closing at $234.53, as investors reacted positively to the Federal Aviation Administration’s decision to allow the 737 MAX 10 to enter the second phase of certification flight testing. The approval, part of the FAA’s Type Inspection Authorization (TIA) process, represents a significant step toward U.S. certification.
Despite this progress, challenges remain. An engine anti-ice system issue continues to affect both the MAX 10 and the smaller MAX 7, keeping the program under scrutiny. Aerospace analysts caution that until certification is finalized, momentum remains fragile.
Scott Hamilton, principal at the Leeham Company, noted, “It’s progress, but until the MAX 10 is certified, it’s not.”
Investor Focus on Delivery Capacity
For investors, the MAX 10 timeline is more than a technical milestone, it’s a measure of Boeing’s ability to fulfill its large order backlog. The jet has more than 1,200 orders, putting it in direct competition with Airbus’ A321neo in the crowded single-aisle market. Successful certification and timely deliveries will be critical to boosting Boeing’s revenue and market positioning.
Market watchers point out that any delays in the anti-ice system modifications could slow initial deliveries, which would weigh on sentiment and potentially erode stock gains. In past certification cycles, advances have often been followed by setbacks, making investor patience a central factor.
Regulatory Scrutiny and Market Reaction
The TIA phase allows Boeing to conduct certification flights under closer FAA oversight. While the agency and Boeing have remained tight-lipped during the pre-earnings quiet period, traders are monitoring the speed and effectiveness of the deicing solution. Smooth progress could boost investor confidence, whereas further delays might prompt BA shares to retrace recent gains.
The broader market environment also provides context for Boeing’s performance. The S&P 500, Dow, and Nasdaq recently reached record highs, supported by a U.S. jobs report indicating slower hiring but a lower unemployment rate at 4.4%. These factors maintain hopes for potential interest rate cuts, offering additional tailwinds for equities, including aerospace stocks.
Earnings Preview Adds Pressure
All eyes now turn to Boeing’s fourth-quarter 2025 earnings, scheduled for release on January 27. CEO Kelly Ortberg and CFO Jay Malave will host a 10:30 a.m. ET conference call to discuss results, including production steadiness, delivery schedules, and cash outlook for 2026. Analysts anticipate that the report could shape market expectations around the MAX 10 timeline and Boeing’s capacity to execute against its backlog.
Investors will also watch for updates regarding the MAX 7 and 10 certification processes. Any delays or unexpected technical findings could push delivery schedules further, affecting revenue forecasts and market sentiment. Conversely, demonstrating progress could reinforce confidence in Boeing’s single-aisle strategy and support BA stock performance.
Certification Key to Momentum
Boeing’s path forward is heavily influenced by the MAX 10 certification timeline. While FAA approval for the next testing phase signals advancement, lingering technical hurdles and the looming earnings report mean that investor focus will remain sharp. Ultimately, the stock’s near-term trajectory is likely to hinge on how quickly Boeing can resolve these challenges and deliver on its single-aisle commitments.
