TransDigm Reported Earnings Last Week. Here's How This Quiet Aerospace Stock Turned $10,000 Into a Fortune.

TransDigm, an aerospace and defense parts supplier, reported strong Q3 fiscal results with sales jumping 23% to $2.74 billion and adjusted EBITDA rising 19% to $1.5 billion. Despite recent pullback, the stock has been a long-term compounder, delivering 23.1% annualized returns since its 2006 IPO at $21 per share, now trading at $1,225.25. The company's success stems from its serial acquisition strategy, quasi-monopoly positioning in mission-critical aerospace components, and strong pricing power.
