This is our final episode in a series of four on TransDigm. In this discussion, we contrast TransDigm with traditional private equity portfolio companies, examine the company’s approach to capital allocation, and dissect Berkshire’s and Stockbridge’s position management over time. Our guest is Rob Small, a Managing Director at Berkshire Partners and Stockbridge, as well as a Director at TransDigm. Under Rob’s direction, Stockbridge has maintained a concentrated position in TransDigm and demonstrated remarkable conviction to add (and occasionally trim) at opportune times.

50X is a podcast that dissects the anatomy of extraordinary long-term investments. The show is hosted by Will Thorndike and the team at Compounding Labs, and brought to you in partnership with Colossus.

In each episode of 50X, we look in detail at an investment that has appreciated at least 50-fold. From the seat of the professional investor and occasionally the CEO, we explore its origins, evolution, and eventual outcome, studying key themes around long-term value creation ranging from operations, capital allocation, and culture to pivotal buy and sell decisions. To enhance the quality and depth of our interviews, we rigorously study each asset in advance, diving into all available public and private resources.
