What Héroux-Devtek does

Héroux-Devtek is a Canadian aerospace manufacturer specializing in the design, development, manufacture, and repair and overhaul of landing gear systems, actuation systems, and related components for commercial and military aerospace customers. Founded in 1938 and headquartered in Longueuil, Quebec, the company operates 18 facilities across North America and Europe with approximately 1,960 employees, ranking as the third largest landing gear manufacturer globally behind Safran (Messier-Bugatti-Dowty) and Liebherr-Aerospace. The company's core product portfolio includes complete landing gear assemblies, hydraulic actuators, electromechanical actuators, custom ball screws, and a global MRO service network supporting products throughout their operational lifecycle.

The business operates as a focused landing gear specialist with three revenue streams: original equipment manufacturing (OEM) under multi-year contracts with major aerospace manufacturers, aftermarket/spare parts sales, and MRO services. Key OEM customers include Boeing (777/777x, F-18, MQ-25, H-47 Chinook), Sikorsky (CH-53K King Stallion), and Embraer, with US Department of Defense agencies providing significant long-term contracts including a $90M four-year US Air Force MRO contract and a $70M seven-year C-130J contract under Canada's Industrial and Regional Benefits policy. Approximately 72% of FY2022 sales ($386.7M of $536.1M CAD total) were generated in the defense sector, with 94% of sales outside Canada and 58% in the US market. Pricing is quote-based through direct B2B relationships under multi-year contracts.

The company was publicly traded on the Toronto Stock Exchange (TSX: HRX) from December 1986 until February 2025, when Platinum Equity completed a take-private acquisition following shareholder and regulatory approvals. Following the divestiture of its Aerostructure and Industrial product lines to Precision Castparts Corp. for $300M CAD in August 2012, Héroux-Devtek has operated as a pure-play landing gear business, with international footprint expanded through acquisitions of APPH Ltd (UK, 2013) and CESA (Spain, 2017).

Direct peers

• Safran Landing Systems: Safran Landing Systems (formerly Messier-Bugatti-Dowty) is the world's largest tier-1 landing gear manufacturer, supplying virtually every major commercial and military aircraft program. It is the most direct competitor to Héroux-Devtek's landing gear and MRO business, and competes head-to-head for OEM slots on Boeing, Airbus, and military programs.
• Collins Aerospace (RTX): Collins Aerospace is a major tier-1 supplier of landing gear, wheels and brakes, and actuation systems for commercial and military aircraft within the broader RTX portfolio. It competes directly with Héroux-Devtek on landing gear programs and offers overlapping MRO services.
• Triumph Group: Triumph Group designs, manufactures, and supports landing gear, actuation, and other aerospace structures for commercial and military customers. Its Aerostructures and Aftermarket segments overlap directly with Héroux-Devtek's landing gear and MRO focus.
• Moog Inc. Moog designs and manufactures high-precision motion control solutions including electromechanical and hydraulic actuators used in landing gear, flight control, and missile applications. It is a direct competitor to Héroux-Devtek's actuation portfolio across military and commercial aerospace.

Broad incumbents

• GKN Aerospace (Melrose Industries): GKN Aerospace is a tier-1 supplier of aerostructures, engine components, and landing gear subsystems, owned by Melrose Industries. It overlaps with Héroux-Devtek's landing gear component and actuation capabilities, though its portfolio is much broader across airframes and engines.
• Magellan Aerospace: Magellan Aerospace is a Canadian tier-1 supplier of complex aerospace assemblies and components, including landing gear components, engine programs, and defense systems. Comparable to Héroux-Devtek as a Canadian-headquartered aerospace supplier with overlapping defense and commercial exposure.
• Curtiss-Wright Corporation: Curtiss-Wright supplies highly engineered, mission-critical components, subsystems, and MRO services for defense and commercial aerospace. Its actuation and defense-focused offerings are comparable to Héroux-Devtek's electromechanical actuator and US DoD-aligned portfolio.
• TransDigm Group: TransDigm owns a portfolio of proprietary aerospace components including actuation and proprietary parts sold to OEMs and the aftermarket. Its business model of high-margin sole-source aerospace components is a useful comparable for Héroux-Devtek's actuator and ball screw positioning.

Emerging players

• LISI Aerospace: LISI Aerospace is a tier-2 supplier of fasteners, small mechanical components, and engineered parts used in landing gear and airframe assemblies. While not a direct landing gear competitor, it supplies into the same OEM supply chains as Héroux-Devtek and competes for adjacent component share.

Others

• Precision Castparts Corp. (Berkshire Hathaway): Precision Castparts acquired Héroux-Devtek's Aerostructures and Industrial product lines in 2012 for $300M CAD and remains a major upstream supplier of forged and cast aerospace components, including landing gear forgings. It is a key supplier-adjacent relationship rather than a direct competitor.
