TransDigm Group boasts a 47.2% operating margin, more than double GE Aerospace's 21.4%, yet GE trades at a higher valuation (43x P/E vs 32x). GE benefits from a predictable recurring revenue stream from its 80,000-engine installed base and cleaner balance sheet, while TransDigm leverages proprietary sole-source aircraft components for pricing power but carries higher debt. The choice between them depends on investor risk appetite: GE for safety, TransDigm for profitability.

TransDigm Group announced a $2.2 billion acquisition of Jet Parts Engineering and Victor Sierra Aviation Holdings from Vance Street Capital. The two businesses provide FAA-approved aftermarket aircraft parts and repair solutions, generating approximately $280 million in 2025 revenue with roughly 700 employees. The deal reinforces TransDigm's focus on specialized aerospace assets with recurring demand, following a recent $960 million acquisition of Stellant Systems.

Stellant generates about $300 million in annual revenue with nearly half from aftermarket sales, aligning with TransDigm's business strategy. TransDigm shares rose 1.05% on the announcement.
