Boeing Stock Drops 4% as CEO Admits 737 Ramp Is Behind Schedule

Boeing shares fell 4% on Wednesday after CEO Kelly Ortberg told investors the company's push to build 47 737 MAX jets a month is taking longer than planned. He didn't sugarcoat it. Speaking at a Morgan Stanley conference, Ortberg pointed straight at a bottleneck nobody outside the industry talks about much: wings.

The Renton, Washington factory that builds those wings simply can't keep pace yet. That single constraint is now the thing standing between Boeing and a production target Wall Street has been counting on for the recovery narrative.

Hitting an even higher rate of 52 jets a month next year — the number Boeing has floated for 2027 — will require both faster wing output and FAA certification of a second 737 line in Everett. Neither of those happens overnight.

The numbers behind the news are the real story for investors. Boeing CFO Jay Malave, speaking at the same conference, said the delay means full-year free cash flow will likely land around $2 billion — the midpoint of January's guidance range — instead of the $3 billion upside case some analysts had modeled in, as Boeing executives disclosed at the event this week.

That's a real gap. A $1 billion swing in free cash flow matters a lot for a company still carrying nearly $26 billion in net debt from years of safety crises and production caps, including fallout from the January 2024 door-plug blowout that capped output at 38 jets a month before regulators lifted the ceiling last October.

"Delayed isn't as good" — the market's blunt read on Boeing's slipping 737 MAX cash flow timeline, reflected in the stock's 4% slide the same day.

Boeing's other cash cow, the 787 Dreamliner, has its own headache. Engine shortages are slowing a planned bump to 10 jets a month; Boeing's stuck at eight for now. Ortberg also flagged that premium-seat certification delays will keep monthly 787 deliveries "lumpy," his word, not a smooth ramp investors can model cleanly.

There's a silver lining buried in the update. Ortberg said the 737 MAX 10 — the largest variant, years behind schedule and roughly 30% of all 737 orders — should get certified "very soon." That's a meaningful unlock if it lands on schedule, since MAX 10 backlog has been sitting dormant waiting on the FAA for years.

He also poured cold water on China-deal hopes tied to the Trump-Xi meeting set for September 24, saying any Chinese airline orders will come "at their own pace" rather than as a headline-grabbing announcement tied to the summit. Investors hoping for a China order pop on that specific date should temper expectations now.

For retail investors holding or eyeing BA, the takeaway isn't panic — it's patience. The long-term recovery thesis (higher production, debt paydown, eventual free cash flow normalization) is still intact. But the timeline just got pushed right again, and that's the second time this year production guidance has slipped on investors.

Watch two things over the next few months: MAX 10 certification news, which could be a real catalyst if it comes through as promised, and any update on the Renton wing bottleneck specifically. If Boeing can show wing output accelerating by year-end, that's the signal the 47-jet target is finally back on track for 2027.

Until then, expect the stock to stay choppy around every conference appearance and earnings call where production numbers come up. A 4% single-day drop on a guidance nuance shows just how sensitive BA remains to any hint that the recovery is taking longer than the bulls have been pricing in.

There's also a debt overhang worth keeping in view. With $26 billion in net debt, every dollar of delayed free cash flow is a dollar not going toward paying that down — which keeps the balance sheet story part of the bear case alive a little longer.

Bottom line: Boeing's turnaround is real, but it's a grinding one, not a straight line up. Size positions accordingly and keep the wing-production headlines on your watchlist.
