2. Operating Leverage: As revenue grows, fixed costs are spread over a larger base, improving EBITDA margins.

Free Cash Flow Per Share grows even faster due to:

1. Capital Efficiency: TransDigm's business model requires relatively low capital expenditures (typically 2-3% of sales).

2. Working Capital Management: Efficient management of inventory and receivables.

3. Tax Optimization: Effective tax planning strategies, including tax benefits from acquisitions.

4. Share Repurchases: Consistent share buybacks reduce the share count, amplifying per-share metrics.

This cascading effect of growth rates - from revenue to EBITDA to Free Cash Flow Per Share - demonstrates TransDigm's ability to efficiently convert top-line growth into shareholder value, underlining the strength of its business model and management's capital allocation skills.
