Boeing's Troubled Net Margin Masks a Bigger Problem

Boeing's (BA) stock price has been under pressure over the past year, down 6.5% compared to the S&P 500's 20.3% return. However, a closer look at the company's financials reveals that its trailing profit is not yet coming out of the operating line.

The company delivered 171 commercial airplanes in the second quarter of 2026, its highest quarterly total since 2018, and revenue over the past twelve months reached $94.0 billion. Net margin across that same period is 2.6%, the best in at least five years and far above a -6.5% three-year average.

However, this net margin figure is not an operating result: the operating margin over those twelve months is -5.4%, better than its own -7.2% three-year average but still negative. The difference between the two margins is driven almost entirely by non-operating income, primarily a one-off ~$9.8 billion gain booked in late 2025.

The current price of Boeing's stock assumes growth of roughly 32.7% a year if margins remain near today's depressed 2.6% level, which is unlikely to happen. While revenue grew 24.8% over the past twelve months, the quarterly pace has stepped down to 8.0% year over year in the June quarter.
