Mark Sotir, President of Equity Group Investments, shares invaluable lessons from his 18 years working alongside legendary investor Sam Zell. In this conversation, he reveals why thinking like an owner rather than an investor fundamentally changes how you build long-term value. (00:17) The discussion centers on three core principles: developing an owner's mindset, focusing on downside protection over upside forecasting, and leveraging long-term capital to create asymmetric returns.
Mark Sotir is the President of Equity Group Investments, the private investment firm founded by the late billionaire Sam Zell. He worked closely with Zell for 18 years until Zell's passing in 2023, gaining deep expertise in long-term value creation and owner-oriented investing. Before joining Equity Group, Sotir had extensive operational experience, having worked at Coca-Cola in marketing and serving as CEO of Budget Rent a Car, Ryder Truck Rental, and a software company.
Sam Zell's foundational teaching was the distinction between being an owner versus an investor. (00:17) As Sotir explains, "He would always say all the time he's an owner, not an investor. And what he meant by that was when we buy businesses and we hold them and we build them. And we're not transactional." This mindset shift fundamentally changes how you approach business decisions - you're not looking for quick exits but building sustainable enterprises. The practical application means taking pride in your investments, being deeply involved in operations, and making decisions with long-term consequences in mind rather than optimizing for short-term gains.
Rather than spending time forecasting potential upside scenarios, successful investors dedicate most of their energy to understanding and mitigating potential downsides. (00:34) Sotir emphasizes that Zell "spent an immense amount of time trying to understand the downside, trying to figure out how to protect us." This approach creates asymmetry - if you're confident you won't lose your principal investment, any positive return becomes attractive. The key is asking yourself: "Are you getting paid for that risk?" This methodology requires thorough due diligence on what could go wrong rather than building elaborate models of what might go right.
Successful long-term investors operate under the assumption that major disruptions happen far more frequently than traditional models suggest. (02:00) As Sotir notes, "we're the kind of place that thinks about the hundred year storm every ten years. We just assume more things are gonna go wrong than you put into your thesis." This translates into practical strategies like avoiding excessive leverage and building flexibility into your business operations. Companies need adaptable management teams and structures that can pivot when unexpected challenges arise - whether it's tariffs affecting an import business or other unforeseen market shifts.
In an increasingly unpredictable business environment, the ability to adapt quickly matters more than accurate forecasting. (03:57) Sotir uses the analogy: "you're simply on a raft in the rapids... what can I do? Have a good raft, have five other people in the boat who are really good, and everybody grabs a paddle." This means building robust teams, maintaining strong balance sheets, and developing organizational agility. Rather than creating detailed five-year plans, focus on building capabilities that allow you to capitalize on opportunities and navigate challenges as they emerge.
Unlike traditional private equity models that rely on exit multiples for returns, long-term value creation requires discipline around cash generation during the ownership period. (10:27) Sotir reveals their portfolio DPI (Distribution to Paid-In capital) is 1.0 for unrealized investments, meaning "out of my entire portfolio, I have all our money out." This approach de-risks investments over time and creates true asymmetry - when you've recovered your initial investment through cash distributions, continued ownership becomes essentially free option value on future growth.
