Supplying parts for nearly all aircraft currently in service, TransDigm (NYSE: TDG) develops and manufactures components and systems for military and commercial aviation.
1. Organic Growth Indicates Solid Core Business
We can better understand Aerospace companies by analyzing their organic revenue. This metric gives visibility into TransDigm’s core business because it excludes one-time events such as mergers, acquisitions, and divestitures along with foreign currency fluctuations - non-fundamental factors that can manipulate the income statement.
Over the last two years, TransDigm’s organic revenue averaged 10.1% year-on-year growth. This performance was solid and shows it can expand steadily without relying on expensive (and risky) acquisitions. 
2. Outstanding Long-Term EPS Growth
Analyzing the long-term change in earnings per share (EPS) shows whether a company's incremental sales were profitable – for example, revenue could be inflated through excessive spending on advertising and promotions.
TransDigm’s EPS grew at 26.8% compounded annual growth rate over the last five years, higher than its 13.9% annualized revenue growth. This tells us the company became more profitable on a per-share basis as it expanded.
3. Excellent Free Cash Flow Margin Boosts Reinvestment Potential
Free cash flow isn't a prominently featured metric in company financials and earnings releases, but we think it's telling because it accounts for all operating and capital expenses, making it tough to manipulate. Cash is king.
TransDigm has shown terrific cash profitability, putting it in an advantageous position to invest in new products, return capital to investors, and consolidate the market during industry downturns. The company’s free cash flow margin was among the best in the industrials sector, averaging 20.4% over the last five years.
