This is our second episode in a series of four on TransDigm, an aerospace components manufacturer that has returned over 1,750X since its inception nearly three decades earlier. If you haven’t listened to the first episode with TransDigm’s founder Nick Howley, we recommend starting there. Today, we are joined by Rob Small. Rob is a Managing Director at Berkshire Partners and has led Stockbridge, Berkshire’s public equities business, since its inception in 2007. Rob conducted diligence on TransDigm in its 2003 auction before investing personally following the IPO, building an anchor position with Stockbridge in 2007, and joining the Board of Directors in 2010.  In this discussion, we cover the core elements composing TransDigm’s business quality, Berkshire’s and Stockbridge’s initial investments, and the trajectory of Rob’s conviction.   For the full show notes, transcript, and links to mentioned content, check out the episode page here.   -----   This episode is brought to you by Tegus.
