Analysts at Bank of America Securities have downgraded Boeing’s stock (NYSE:BA) from Buy to Neutral, citing concerns about its future profitability. The airplane manufacturer is expected to face increased scrutiny from aviation authorities, amplifying worries about the quality and safety of its planes.

Commenting on the situation, Ronald Epstein, an analyst at BofA, stated, “To be blunt, the current situation is not tenable. We move to the sidelines with our rating on the shares.”

The downgrade follows the U.S. Federal Aviation Administration’s decision to disallow Boeing (BA) from increasing production of the 737 Max jetliner. However, the agency has permitted grounded planes to resume flying after undergoing thorough inspections.

About 170 of Boeing’s 737 Max 9 were grounded on January 6 following a midair emergency on an Alaska Airlines flight. A metal plug used in place of an exit door blew out from the plane’s cabin just minutes after takeoff, causing the aircraft to depressurize at 16,000 feet.

As a result of the downgrade, BofA has reduced its earnings estimate for Boeing (BA) to $0.25 a share from $2.70 a share for 2024, and to $6.35 a share from $7.45 a share for 2025.

The bank believes that the temporary slowdown will enable Boeing (BA), its suppliers, and regulators to focus on quality assurance and best-in-class production practices without the stress of ramping up production in the near term. They expect this to ultimately equip Boeing to increase production rates smoothly.
