TransDigm (TDG) Stock Forecast & Price Target

TransDigm Group is supported by a powerful mix of proprietary, sole-source aerospace content, strong aftermarket exposure, and long-standing defense relationships, including winning every major parachute competition over the past 25 years. Its commercial aftermarket has re-accelerated to about 17% in calendar 2Q26, defense sales grew 13% organically in FY25, and FY26 guidance still implies high-single-digit to low-double-digit growth with adj. EBITDA margins around 52.5%. The company’s acquisitive model, more than $10B of remaining M&A capacity, and willingness to run 5x to 7x leverage create additional upside through deal-driven growth and capital deployment, while robust margins and resilient end-market demand support the bullish view.

TransDigm Group is viewed cautiously because its commercial aftermarket growth has lagged peers, with TTM and 24-month averages of 12.3% and 12.1% versus 16.8% and 16.3%, while EBITDA margins appear to have peaked around 52%-53% after a ~100bp step-down from a year ago. The company’s leverage-heavy, acquisition-led model is facing tougher regulation, DOJ scrutiny, and “Right to Repair” risk, highlighted by the Stellant withdrawal in early July 2026, which could make accretive deals harder to source and integrate. With net debt/TTM EBITDA at 5.8x as of FY25 and 3Q26, plus rising rates and reliance on debt-funded special dividends and buybacks, future value creation looks less durable and more exposed to multiple compression.
