There’s a line in Boeing’s footnotes that says the company paid $8.4 billion for something worth negative $1.9 billion. That isn’t a typo and it isn’t a scandal. It’s a supply chain. But it is also, as the Journal’s Jonathan Weil lays out, a loss that never touches the income statement — and since Boeing (BA) is a name we hold, it’s our loss to read about.
Start with the official number. Boeing lost $339 million before taxes in the first half of 2026, after briefly turning a profit last year thanks to asset sales. Weil’s point is that the figure doesn’t capture the red ink flowing from the company’s biggest acquisition in years: the December purchase of Spirit AeroSystems, its longtime and visibly struggling fuselage supplier, which traded as SPR until Boeing absorbed it.
The plug number
When a company buys another, it inventories every identifiable asset and liability at fair value; whatever is left of the price is called goodwill. Boeing paid $8.4 billion in stock, loan settlements and debt repayments, and as of Dec. 31 it allocated $10 billion of that to goodwill. Read that again. After scouring Spirit for everything it could name, management concluded the assets were worth $1.6 billion less than the liabilities. Accounting rules give an acquirer a year to refine the allocation, and by June 30 the refinement had gone the wrong way: the deficit grew to $1.9 billion and goodwill rose to $10.3 billion — more than Boeing’s entire equity.
| Spirit purchase, per Boeing’s footnotes | Dec. 31 | June 30 |
|---|---|---|
| Price paid | $8.4 billion | $8.4 billion |
| Allocated to goodwill | $10.0 billion | $10.3 billion |
| Identifiable assets less liabilities | -$1.6 billion | -$1.9 billion |
The main driver was a $455 million increase in the estimated liability for what Boeing calls “off-market customer contracts,” where “the terms of the contract deviated from the terms that a market participant could have achieved.” Their fair value is now about $1.5 billion. In plain English: the contracts are a money pit, and they’re deeper than management thought nine months ago. Economically those are real losses — greater costs on deeply unfavorable contracts at below-market prices. Under the rules they show up as a bigger goodwill number rather than a worse quarter.
Why it matters to a shareholder
Goodwill isn’t amortized. It sits there until somebody decides the deal isn’t worth what was paid, and then it gets written down — first, and all at once. It is rare for a company to assign more than 100% of a purchase price to goodwill. When the goodwill on one deal exceeds the whole company’s equity, an impairment isn’t a rounding error; it’s a number that could take book equity below zero. Nobody here is calling that outcome. The point is the size of the line and the direction it has moved in six months.
Why Boeing bought it anyway
Because it had to. About 58% of Spirit’s revenue came from Boeing in 2024, its last full year on its own; Spirit was the sole source for nearly everything it sold Boeing, and it was drowning in losses. Spirit built the fuselage of the Alaska Airlines (ALK) jet whose door plug blew out midflight; a federal investigation faulted Boeing, and the episode forced the plane maker to bring more of its supply chain under its own roof. Spirit, knowing all this, extracted a large premium. Boeing shareholders have lived through setback after setback since the stock peaked in 2019 — a parade of safety lapses, including two fatal crashes. This one is quieter, and it’s in the footnotes.
A Boeing spokesman declined to answer questions about the accounting. In a statement, he said the integration of Spirit’s commercial operations “is progressing well and remains an important part of strengthening the company’s production system, quality performance and capability to meet future rate increases.” That may well be true. It can be true at the same time the contracts lose more money than anyone admitted in December.
