This is one of the more rigorous investment write-ups I've come across on Substack. The sum-of-the-parts approach is the right framework for a conglomerate this complex, and Pete's transparency about assumptions at every layer — discount rates, growth rates, combined ratios, capitalization multiples — gives you enough to disagree with specific inputs without dismissing the whole thesis. The Berkshire replication question is the heart of this. Every generation of investors produces someone who wants to build the next Berkshire, and virtually every attempt has failed. Pete identifies the right reasons why — most prior attempts were financing vehicles for hedge fund fee extraction, not genuine long-term compounding structures. The Pershing fee arrangement is better aligned than most, but the reference price issue is a real concession that minority shareholders are subsidizing. Acknowledging that while still building a constructive case is the kind of honest analysis that's rare in public stock write-ups. The MPC business is the part I find most compelling and most underappreciated. A 50-60 year buildout timeline with monopolistic control over land supply in growing metros is a genuine structural moat. The Summerlin 7% residential price growth assumption over 17 years is the input I'd scrutinize hardest — that's a long extrapolation in a single metro, and Las Vegas has historically been more cyclical than most Sun Belt markets. The real test is whether Ackman can resist the temptation to get clever. Buffett's compounding came from decades of disciplined, often boring capital allocation. The Pershing track record is exceptional but built on a concentrated, high-conviction style that's produced spectacular volatility alongside the returns. Berkshire's durability came from boring consistency. Whether Pershing can deliver that over decades is the open question no spreadsheet can answer. For anyone following HHH — what's the one assumption in the thesis that would change your mind if it broke?
