Revisiting Boeing After the FAA's Latest Safety Crackdown

Our earlier piece — 'Boeing's F-47 Fighter Jet Win Signals a Defence Pivot That Changes the Investment Case' — laid out a straightforward argument. The $20 billion+ F-47 contract, combined with existing defence programmes, gave Boeing a stable revenue base of roughly $25-30 billion annually. Against that backdrop, any improvement in commercial production rates represented pure upside.

The stock was trading around $180 at the time. We weren't bullish exactly — the commercial headwinds were real — but we saw the risk-reward as asymmetric. The defence floor limited downside to perhaps 15%, while a commercial recovery offered 40-50% upside over two years.

The FAA's latest actions have changed that calculus.

Boeing's 737 MAX production was capped at 38 aircraft per month following the Alaska Airlines door plug incident. The company had been targeting 50 per month by mid-2025. That target has been pushed to late 2026 at the earliest, and frankly, even that timeline feels optimistic given the supply chain constraints we're seeing across aerospace.

Every month at 38 instead of 50 costs Boeing roughly $400-500 million in deferred revenue and margin. Over 18 additional months of rate restrictions, that's $7-9 billion in foregone revenue. The 787 line faces its own challenges, with quality inspections slowing deliveries below the target rate of 10 per month.

The historical pattern is clear. The pattern is depressingly consistent: timeline estimates from management are 40-60% too optimistic, and cost estimates are 20-30% too low. Apply that historical error rate to Boeing's current guidance and the numbers get uncomfortable.

Boeing carries $52 billion in long-term debt against $10.5 billion in cash. That's a net debt position of over $40 billion — staggering for a company generating barely positive free cash flow. Interest expense alone runs $2.5-3 billion annually, consuming virtually all of the operating profit the company manages to generate.

The credit rating agencies have Boeing on a tight leash. Another production setback or significant quality event could trigger a downgrade to junk status, which would raise borrowing costs and potentially force asset sales. This is the tail risk that keeps us cautious.

At 89x trailing earnings and 154x forward, the stock is pricing in a recovery that hasn't materialised yet. The market is paying for 2028 Boeing at 2026 prices, and the bridge between here and there is longer and more treacherous than the consensus assumes.
