I Squared Capital agreed to acquire Orizon Aerostructures for a price estimated at $2 billion on October 28, 2026. The transaction places a major global infrastructure investment manager in control of an advanced aerospace manufacturer responsible for supplying the Lockheed Martin F-35 Lightning II and the Boeing 737 Max. The agreement addresses severe supply chain capacity constraints across the commercial aviation and defense sectors. The transaction is expected to close in the fourth quarter of 2026.
Private equity firms focused on infrastructure are expanding their definitions of the asset class to include industrial manufacturing. Firms traditionally focused on toll roads and power plants are now buying suppliers protected by high regulatory barriers and life-of-program contracts. These businesses offer decades of revenue visibility and strict cost-pass-through provisions. The acquisition of Orizon Aerostructures demonstrates this shift, as financial sponsors seek stable cash flows inside the highly regulated defense and commercial aerospace supply chains.
Orizon Aerostructures carries an order backlog exceeding $3.1 billion, supported primarily by a multiyear supply agreement with Lockheed Martin. The Kansas City-based target operates five specialized manufacturing facilities across Kansas and Oklahoma with a workforce of more than 900 employees. The size of this backlog forces the incoming owner to deploy immediate capital to expand machining and assembly capacity. The structural bottleneck in airframe production determines the rate at which original equipment manufacturers can fulfill their own orders.

Advisers
I Squared Capital did not disclose its financial or legal advisers for the transaction. Orizon Aerostructures and its existing investor, American Industrial Partners, also did not publicly disclose their advisory teams in the official announcement on October 28, 2026. In a previous capitalization event in 2020, Jones Day advised American Industrial Partners on its $50 million investment into Orizon. The current M&A advisers remain private.
How the deal came about
Aerospace manufacturers have struggled to meet production quotas set by defense and commercial contractors following the pandemic. Original equipment manufacturers such as Boeing and Lockheed Martin require suppliers capable of immediately delivering large, complex structural components at scale. Orizon Aerostructures spent the last several years consolidating production capacity. The founders, Charlie and Henry Newell, expanded the business by acquiring existing production facilities, including a former Spirit AeroSystems location in Chanute, Kansas.
American Industrial Partners injected $50 million into Orizon Aerostructures in December 2020 to fund capacity expansion. The investment consisted of a loan and an equity component from AIP Fund VII and Industrial Credit Partners. This capital allowed Orizon Aerostructures to automate its facilities and secure large contracts. By 2025, the company secured a multiyear contract with Lockheed Martin that pushed its order book above $3.1 billion.
I Squared Capital identified high-precision aerostructures manufacturing as an asset class sharing the traits of traditional infrastructure. Managing Partner Gautam Bhandari stated that aircraft production requires investment in specialized capacity deeply embedded in programs spanning decades. I Squared Capital entered advanced negotiations with Orizon Aerostructures in late October 2026. The parties signed a definitive agreement on October 28, 2026.
Valuation and comparables
The official press release from Business Wire on October 28, 2026, explicitly withheld the financial terms of the acquisition. Briefs Finance and Bloomberg reported on October 27, 2026, that the transaction implied a valuation of roughly $2 billion. Neither party disclosed the target’s earnings before interest, taxes, depreciation, and amortization, nor the revenue figures required to calculate precise valuation multiples.
Recent aerospace transactions provide context for valuation multiples in the sector. In September 2026, GE Aerospace announced plans to acquire Consolidated Precision Products. While the exact multiples for the GE transaction remain private, defense contractors and aerostructure manufacturers with life-of-program contracts typically trade at a premium due to high barriers to entry and long-term revenue visibility. Financial sponsors value the cost-pass-through provisions built into these contracts, as they protect margins from raw material inflation.
Financing and structure
I Squared Capital did not disclose the financing structure for the $2 billion acquisition. The firm manages roughly $60 billion in assets. The split between equity committed by I Squared Capital’s managed funds and third-party debt facilities remains unconfirmed.
Orizon Aerostructures previously relied on private credit and equity funding. American Industrial Partners provided a $50 million investment in 2020 through a loan originated by Industrial Credit Partners and equity from AIP Fund VII. The new ownership structure will require I Squared Capital to retire or assume existing debt obligations. I Squared Capital plans to invest additional capital into Orizon Aerostructures to resolve supply-chain bottlenecks and expand manufacturing capacity.
Risks, conditions and key dates
- December 28, 2020: American Industrial Partners invested $50 million into Orizon Aerostructures to fund facility expansion and automation.
- July 20, 2026: Orizon Aerostructures formed a strategic alliance with Wichita State University’s National Institute for Aviation Research to accelerate production ramp-up.
- October 27, 2026: Bloomberg and Briefs Finance reported advanced negotiations between I Squared Capital and Orizon Aerostructures at an implied $2 billion valuation.
- October 28, 2026: I Squared Capital announced the definitive agreement to acquire Orizon Aerostructures.

Where reports disagree
The primary source documents and financial news reports contain two specific discrepancies regarding the transaction and the target company. The official press release published by Business Wire on October 28, 2026, states that the financial terms of the transaction were not disclosed. Conversely, Briefs Finance and Bloomberg reported on October 27, 2026, that the negotiations implied a valuation of roughly $2 billion.
A second discrepancy exists regarding the founding date of Orizon Aerostructures. The October 28, 2026, Business Wire announcement states that the company was founded in 2016. A press release from January 6, 2021, detailing the American Industrial Partners investment also cites 2016 as the founding year. However, pre-deal reporting by Briefs Finance on October 27, 2026, reported that brothers Charlie and Henry Newell established the company in 2017.
