Are margins and cash flow holding steady?
FundamentalsFor the year ended September 30, 2025 (reported in USD), TransDigm held USD 2.8 billion of cash and USD 248.0 million of total debt, with revenue of USD 8.8 billion. Profitability was sizable, including EBIT of USD 4.2 billion and net income of USD 2.1 billion.
Cash generation, measured by the platform’s proxy, was USD 3.6 billion, while capital spending was USD 222.0 million and depreciation and amortization was USD 163.0 million. On a trailing basis, margins remained elevated, with a 59.90% gross margin, 46.35% operating margin, and a 22.24% net profit margin, alongside 11.2% year-over-year revenue growth.
Is the stock pricing in durability?
DCF / MultiplesAt USD 1,233.11, the stock trades above the weaker DCF outcome but below the central and stronger outcomes in the DCF range. The current pricing also aligns with a 34.10 P/E and 21.66 EV/EBITDA on a trailing basis.
Cash strength supports valuation
TakeawayThe balance sheet currently looks cash-rich and lightly levered. Durability needs to keep showing up as high operating profit. The valuation works best if cash generation stays close to recent levels. The main risk is a drop in earnings power from today’s margin profile.
