Boeing Stock Slumps on Software Glitch in 737 MAX Aircraft

Boeing's stock price fell by 3% on Thursday after a software glitch was discovered in its 737 MAX aircraft, which can disable an automated navigation function during landing.

The issue, which affects autopilot functions at low altitude, has drawn regulatory scrutiny from the U.S. authorities, who are reviewing the problem to determine the scope of any required fix.

Boeing's $715 billion backlog remains intact if regulators accept a software patch as the solution, but any broader fix could delay the company's 2026 certification targets for its 737-7 and 737-10 models.
