What are the key takeaways from this Business Breakdowns episode?

Key insights include: **Razor-Razorblade Economics:** GE sells engines at break-even or loss to Boeing and Airbus, then captures 60% gross margins on mandatory aftermarket services over 25-year aircraft lifespans, generating three to five times the original equipment sale value.; **Duopoly Barriers:** Developing jet engines costs $10 billion and requires atomic-scale precision in manufacturing where microscopic contaminants cause fleet-wide recalls. Only three companies globally can manufacture at scale, with China's COMAC choosing GE engines despite state backing.; **Predictable Revenue Model:** Seventy percent of GE revenues come from services, driven by regulatory mandates requiring engine overhauls every six to seven years. Airlines avoid third-party parts to maintain warranties, creating exclusive revenue streams with seven years of backlog visibility.

Now if you go by tickers, we did break down GE several years ago, but that episode focused on how Larry Culp at the time was turning around that Titanic that was GE, the conglomerate. Today, Ramesh Narayanaswamy, cofounder and portfolio manager of Tubian Partners, join me to go deeper on what is now a pure play aerospace business. So we get into some of the unique dynamics of the supply chain in aerospace, the long cycle nature that differentiates it from many other industries that you look at. And I marvel a bit on the complexity that is aircraft engine manufacturing, but not for long because this is another beautiful example of selling services attached to equipment. And I first met Ramesh back in the 2024 at a business breakdowns event. It did not take long for me …
