Why Is BOEING CO (BA) Stock Down Today?

Boeing shares fell 10.69% to close at $168.18 on Tuesday. The primary driver was a disappointing third-quarter earnings report, which included a warning that the company’s path to stabilizing 737 production has slipped into 2027.

What Happened

Boeing reported that supplier shortages during the third quarter disrupted factory operations, adversely affecting the KC-46A tanker and 777 freighter programs. The company expects these disruptions to continue into 2027, resulting in abnormal production costs that will be expensed as incurred. Consequently, the first delivery of the 777-8 passenger aircraft is not expected to occur before 2030.

Management also revised its timeline for the 737 program, stating it now expects to reach the production target of 47 aircraft per month in 2027, later than originally planned. Despite these operational headwinds, the company highlighted a record backlog of $745 billion and outlined a path to $10 billion in cash flow. Boeing also disclosed that it received approximately $420 million in refunds related to prior tariff assessments during the nine months ended September 30.

What The Data Shows

The stock’s decline pushed it to a fresh 52-week low, with the 52-week range now standing between $176.77 and $254.35. Over the last eight sessions prior to this move, the stock had gained 1.0%, rising from $183.95 to $185.74. Unusual options activity in the last 36 hours included 35 notable prints, with put premium of $25.0 million outweighing call premium of $15.5 million. The largest single print was $6.0 million.

Fundamentals show a market cap of $148.9 billion and a P/E ratio of 70.2. Revenue grew 24.8% on a trailing twelve-month basis, while the net margin stood at 2.6%. The stock has a beta of 1.26. Congressional disclosures in the last 90 days show five buys and nine sells, with the most recent filing on October 8, 2026.

What To Watch

Investors will monitor Boeing’s progress toward its 2027 production targets and the impact of ongoing supplier shortages on abnormal production costs. The company’s ability to convert its record backlog into cash flow remains a key metric for the near term.
