Kaplan Fox & Kilsheimer Investigates Boeing After 10.7% Share Drop on 737 MAX Outlook

Kaplan Fox & Kilsheimer LLP is investigating The Boeing Company for potential securities law violations, the firm said in a press release carried by The future of trading. Boeing shares fell over $20 per share, or 10.7%, on October 27, 2026, after third quarter 2026 results showed 737 MAX production stabilization taking longer than expected and a cut to the full-year aircraft delivery outlook.

Boeing's 737 MAX Rate And The July Guidance

The investigation centers on the gap between Boeing's July 28, 2026 statements and its October 27, 2026 results. In reporting second quarter results, Boeing said it was "on track to deliver 500 airplanes this year." The Wall Street Journal reported on October 27, 2026 that Chief Executive Kelly Ortberg told investors the step up to 47 jets a month on its 737 MAX production lines "didn't go as smoothly" as the previous rate increase, a challenge that affects profitability, and that the company does not expect to hit that more lucrative production rate until next year. Kaplan Fox said it is seeking investors who suffered losses or who have information that could assist the investigation. The firm lists Laurence D. King and Pamela A. Mayer as contacts.
