Goldman Sachs analyst Noah Poponak maintains a bullish outlook on Boeing Co. (NYSE:BA) despite its weak Q3 performance, citing it as a 'long-term deep-value opportunity.' Poponak reaffirms a Buy rating with a $200 price target, highlighting robust aircraft demand, planned capital raises, and new leadership as key factors for recovery. Boeing's Q3 results showed revenue of $17.84 billion and a core EPS loss of $(10.44), with significant losses in the Commercial Airplanes segment due to production setbacks and a machinists' strike. The Defense, Space & Security division also faced challenges, while Global Services showed improved margins. Boeing plans to raise $18 billion to support its balance sheet amid ongoing labor disputes and production challenges.
