GE Is Buying Its Own Supplier to Escape the Aerospace Castings Bottleneck

The whole aerospace industry has been stuck, for a few years now, on castings — the metal parts, made by pouring molten super-alloy into a mold, that hold a jet engine together. Not the software, not the final assembly. The castings. They keep getting flagged again and again as the supply chain's constraint, the single component that can leave an aircraft worth hundreds of millions of dollars sitting on the ground waiting for one part to arrive.

So when GE Aerospace said Tuesday it would buy Consolidated Precision Products — one of the world's largest producers of precisely the things the whole industry is waiting on — the detail somewhat lost in the noise was this: GE has been buying castings from that same company for more than fifteen years. That is the structure of the deal in one line: GE finally got tired of waiting for its supplier, so it bought the supplier.

The price of making your own

The check is $11.75 billion in cash, paid to the private equity firms that own CPP, Warburg Pincus and Berkshire Partners. $7 billion comes out of GE's own cash; the rest is new debt. By GE's own math, the price is about 26 times CPP's expected 2027 profit — or roughly 18 times, once you add in the $200 million of "synergies" GE says it can find. Management expects it to boost GE's adjusted earnings per share and free cash flow in the first year, and to close in the second half of 2027.

That "adjusted" is doing real work, and it's worth pausing on. This is a company buying at 26 times the target's core profit, funding a big chunk with debt, and calling it immediately accretive to adjusted earnings and cash flow. Money Stuff's rule here is that the sentence tends to be true in every number and not mean what it sounds like it means: the accretion shows up in GE's adjusted math, not in the GAAP math. Fine. But it's worth noticing which metric the whole claim is built on.

Then there are the synergies, which is the part I'd actually keep an eye on. $200 million of recurring savings sounds small next to an $11.75 billion check. But CPP's standalone 2027 profit is only about $450 million — that's what paying 26 times on $11.75 billion implies. So $200 million of synergies against $450 million of standalone core profit means GE believes it can add almost half again to CPP's profit through efficiency, process, and the magic of ownership — at a company it won't control until late next year, in a business (casting) that is famously hard and slow to scale. The whole price is built on squeezing that extra $200 million out of a business GE doesn't run yet. That's not a criticism; it's the arithmetic on the disclosed multiples, and it's the arithmetic that decides whether this turns out to be a good price.

Owning the supplier everyone else needs

Why do it at all? Because GE has decided it would rather own the bottleneck than keep bidding for capacity in a market where everyone wants the same castings at once — commercial engines, aftermarket, and defense. This is the ancient make-versus-buy decision, reappearing as an $11.75 billion footnote to the castings problem. GE pairs its process technology with CPP's factories to push more parts through the same plants. When your supplier is the constraint on your entire industry, paying up to own the supplier stops looking like an expensive multiple and starts looking like insurance.

But here's where the ownership gets genuinely strange, in a way that doesn't fit cleanly into "GE bought a supplier." CPP is not a captive shop that only makes parts for GE. It is a merchant supplier, one of the world's largest, selling castings across commercial aircraft, the military, helicopters, weapon systems, and industrial gas turbines. GE isn't just buying capacity for its own engines; it's buying a big chunk of the industry's common supplier. Which raises a question the press release doesn't dwell on: what happens to CPP's customers who aren't GE — and, in some cases, are GE's competitors? The castings maker that used to sell to everyone now lives inside one of the people it sold to. There is a perfectly good version where GE, having paid up for the access, keeps serving the whole market. There's a less comfortable version where GE's rivals start to wonder whether they want their critical castings coming out of a division of the company they compete with.

The same point hides, slightly darker, inside GE's own structure. GE's flagship commercial engine business is largely a fifty-fifty joint venture with Safran — the CFM engines that power so much of the single-aisle fleet — so even the "GE" engines these castings feed aren't purely GE's. GE is buying a big position in shared industry capacity, partly for engines it merely co-owns. Two reasonable people will describe the same deal very differently: GE calls it securing mission-critical supply; a competitor calls it a rival taking control of the industry's common input. Both sentences are true.

The market shrugged at the announcement; GE shares were roughly flat. Maybe that's the tell. At 26 times projected core profit, with a large synergy bill and debt on top, this isn't a discount acquisition — it's a strategic bet priced so that the sellers, Warburg Pincus and Berkshire Partners, made out well. For a shareholder, the interesting question isn't whether castings matter; they clearly do. The question is whether GE has the discipline to turn what amounts to a 44% profit uplift on a business it doesn't own yet into real cash, and whether buying everyone's supplier ends up being a moat or just a way of buying a fight you used to be neutral in. Buy the bottleneck by all means. Just count how much of the price is a promise about your own future skill.
