Market Cap: US$227 million

"The growing regulatory pressure to modernize aircraft for sustainability and safety, exemplified by the upcoming 2026 FAA Airworthiness Directive compliance deadline for fuel tank wiring, has led to an accelerating backlog for AerSale's AerSafe product."

How far AerSale can translate that kind of regulatory-driven backlog into lasting pricing power and steadier margins hinges on one unresolved pressure.

Operations: Luxfer generates about $186 million from Elektron specialty materials and $175 million from Gas Cylinders, with most revenue coming from the United States.

Market Cap: US$461 million
