Why did TransDigm pay such large dividends?
The company's model generates far more cash than its operations can reinvest, so it periodically issues debt-funded special dividends: $75 per share in October 2024 and $90 per share in September 2025, about $9.6 billion total. The policy is a deliberate part of its private-equity-style capital allocation.

What was the DoD controversy about?
