Boeing Stock Fell 7% in a Day on the MAX 10 Delay. Here’s What It Means for 2027 Cash Flow
Boeing (BA) shares fell 6.91% to $184.39 on September 28 after the FAA delayed MAX 10 certification due to a software glitch. CFO Jay Malave linked the delay to 2027 cash flow, as stored jets will be delivered post-certification. Analysts expect free cash flow to reach $6.0 billion in 2027, but Malave cautioned it may still be a transitionary period. Boeing's market value is about 15 times 2028 consensus free cash flow.
