GE Aerospace to Buy CPP Castings Maker for $11.75B

The company buys its own bottleneck

GE Aerospace announced on September 8, 2026 that it has agreed to acquire Consolidated Precision Products (CPP), a privately held manufacturer of engineered castings and forged components for commercial and military aircraft, for $11.75 billion. The seller is a consortium led by private equity firms Warburg Pincus and Berkshire Partners, according to GE Aerospace's own press release and reporting confirmed by Bloomberg, CNBC, Reuters and Aviation Week.

The deal is notable less for its size — sizable as $11.75 billion is — than for what it says about where the real constraint sits in commercial aviation's engine supply chain right now. It is not final assembly lines that are the bottleneck; it is the far less visible layer of suppliers who cast and forge the metal components — turbine blades, structural housings, fan cases — that go into engines like the CFM LEAP and GE's GEnx before GE or CFM ever touches them.

Who CPP is, and why GE already knows them well

Consolidated Precision Products, based in Cleveland, Ohio, makes investment castings, sand castings and forgings used across commercial aerospace, defense and industrial-turbine applications. The company operates more than 20 facilities and employs roughly 6,600 people, according to GE Aerospace's disclosure. It is one of the largest independent producers of precision castings in the world, supplying not just GE but other engine and airframe manufacturers as well.

Crucially, this is not a new relationship. GE Aerospace has been a CPP customer for more than 15 years, and CPP-made parts are already embedded in engine programs including the CFM LEAP — the engine that powers the Airbus A320neo family and the Boeing 737 MAX — and the GEnx, which powers Boeing 787 and 747-8 aircraft. GE Aerospace's press materials describe the acquisition as intended to "expand mission-critical castings capacity" rather than to enter a new line of business, framing it explicitly as a vertical-integration move rather than a diversification play.

Why GE Aerospace is buying its castings supplier rather than just ordering more from it

The money: how it's structured

GE Aerospace plans to fund $7 billion of the purchase price in cash, with the remaining roughly $4.75 billion financed through new debt issuance, per the company's own statement and confirmed by CNBC's coverage of the transaction. The deal values CPP at approximately 18 times its projected 2027 EBITDA once expected synergies are included, or about 26 times EBITDA on a standalone basis before synergies — multiples that sit at the high end for an industrial-manufacturing acquisition, reflecting how tight capacity has become across the aerospace casting and forging sector industry-wide.

The transaction is expected to close in the second half of 2027, subject to regulatory approval and other customary closing conditions — a timeline of well over a year, which is typical for a deal of this size given the antitrust and national-security review such a large defense-adjacent manufacturing acquisition is likely to face in the United States. GE Aerospace has said it expects the deal to be accretive to adjusted earnings per share and free cash flow in its first full year following completion, though that projection assumes the deal closes on schedule and integration proceeds without the kind of manufacturing disruption that can accompany large industrial mergers.

Why now: the industry-wide casting crunch

The aerospace industry has spent the past several years working through a well-documented shortage of forging and casting capacity — a problem that predates this specific deal and has contributed to persistent delivery delays at both Boeing and Airbus. Independent casting houses like CPP, Howmet Aerospace and PCC (Precision Castparts, itself owned by Berkshire Hathaway) supply the metal components that sit upstream of every engine and airframe assembly line, and when that upstream capacity can't keep pace with order books, the bottleneck ripples downstream into missed delivery targets for finished aircraft.

CFM International — the joint venture between GE Aerospace and Safran that builds the LEAP engine — has been running near-record order and delivery volumes, underscored by a string of large LEAP commitments signed at trade events earlier in 2026, including an agreement with IndiGo for more than 1,000 LEAP-1A engines. That kind of order backlog only intensifies pressure on suppliers like CPP to scale casting output, and buying the supplier outright gives GE Aerospace direct control over capacity allocation and capital investment decisions that it previously had to negotiate for as an external customer.

What it doesn't fix, and what to watch

Owning CPP does not, by itself, solve the industry's broader raw-material and skilled-labor constraints — the specialty alloys, furnace capacity and trained machinists that castings production depends on are still finite resources that GE Aerospace will now compete for more directly rather than through arm's-length purchase orders. Nor does the deal close quickly enough to affect near-term 2026 or 2027 delivery numbers; with completion not expected until the second half of 2027, any capacity benefit is a multi-year proposition, not an immediate fix for current LEAP or GEnx delivery timelines.

It's also worth noting that CPP is not exclusively a GE supplier — it serves other aerospace and defense customers as well, which means the acquisition raises questions about how GE Aerospace will manage CPP's existing commitments to competitors or other engine programs once GE owns the company outright. Neither GE's press release nor the wire coverage reviewed for this article detailed how existing third-party contracts will be handled post-acquisition, and that is a detail worth watching as the deal moves through regulatory review over the next year.

For an industry that has spent years explaining away late aircraft deliveries with reference to an invisible tier of suppliers nobody outside the trade press had heard of, GE Aerospace's answer is characteristically blunt: if you can't out-order the bottleneck, buy it.

A pattern of vertical integration across the industry

GE Aerospace's move to acquire CPP is not happening in isolation. It follows a broader trend of engine and airframe manufacturers pulling supply-chain capacity in-house after years of watching outside suppliers struggle to keep pace with post-pandemic demand recovery. The most direct parallel is Berkshire Hathaway's ownership of Precision Castparts (PCC), which Warren Buffett's conglomerate acquired in 2016 for roughly $37 billion — at the time the largest acquisition in Berkshire's history — precisely because PCC's castings and forgings were viewed as an irreplaceable choke point across both commercial and defense aerospace supply chains. Boeing, for its part, moved in the same direction with its 2024 agreement to reacquire Spirit AeroSystems, the fuselage and structures supplier that Boeing had spun off two decades earlier, after quality and delivery problems at Spirit contributed to production slowdowns on the 737 MAX line. GE Aerospace buying CPP fits that same logic: when an external supplier becomes so critical that its capacity constraints directly cap your own output, owning it outright starts to look cheaper than continuing to negotiate for priority as just one customer among several.

That logic has hardened since the pandemic. Aerospace manufacturers spent much of 2020 and 2021 cutting orders and idling capacity as air travel collapsed, and many specialty-metals suppliers, foundries and forge houses either shut down permanently or shed skilled workers who never returned to the industry. When commercial aircraft demand rebounded faster than the supply base could restaff and reinvest, the resulting mismatch became one of the most persistent stories in aviation manufacturing: both Boeing and Airbus have repeatedly cited castings and forgings shortages, alongside engine-parts delays, as reasons for missing their own delivery targets in recent years. GE Aerospace CEO Larry Culp has spoken publicly and repeatedly about supply-chain constraints as the single biggest limiter on how fast GE and CFM can grow LEAP and GEnx output, which is the immediate business context behind paying a premium multiple for CPP now rather than waiting for the broader capacity crunch to ease on its own.

The LEAP engine's outsized stakes

The CFM LEAP engine sits at the center of why this deal matters as much as it does. LEAP is the sole engine option on the Boeing 737 MAX and one of two engine choices (alongside the Pratt & Whitney GTF) on the Airbus A320neo family, which makes it the single highest-volume commercial jet engine program in the world by units on order. CFM's backlog runs into the tens of thousands of engines, built up over more than a decade of narrowbody orders from airlines worldwide, and every one of those engines depends on castings and forgings — turbine blades that must withstand temperatures inside the combustor that exceed the melting point of the metal itself, thanks to sophisticated cooling designs, plus structural cases and housings that have to meet exacting tolerances no ordinary metal shop can produce. A shortfall anywhere in that casting supply chain doesn't just delay one engine; it delays every aircraft waiting on that engine to be installed, which is why CFM's order momentum in 2026, including large commitments from carriers like IndiGo, has translated directly into pressure on suppliers like CPP to expand output faster than arm's-length contracts alone could guarantee.

Regulatory and integration questions ahead

Because CPP supplies castings and forgings used in defense programs as well as commercial engines, the deal is expected to draw scrutiny not just from antitrust regulators evaluating market concentration in the casting and forging industry, but potentially from US national-security reviewers concerned with a major defense-adjacent supplier changing hands. That combination — a large industrial acquisition plus defense-relevant manufacturing — is part of why GE Aerospace and the sellers have set a closing timeline stretching into the second half of 2027 rather than expecting a faster turnaround. During that review period, CPP is expected to continue operating and fulfilling its existing contracts as an independent company, and GE Aerospace has given no indication that it plans to change CPP's relationships with other customers before the deal closes.
