The Intrinsic Value Podcast discusses Constellation Software (CSI), a company often dubbed the "Berkshire Hathaway of software." The stock recently experienced its largest-ever drawdown, plummeting 50% amidst the AI narrative, despite founder and former CEO Mark Leonard (who stepped down in September 2023 due to health) having stated in early 2025 that the stock was overvalued and investors should expect only 8% returns at those levels. He suggested a "massive drop" was needed for 25% annualized returns.
Mark Leonard's background is unique, having worked diverse jobs before entering venture capital and founding CSI in 1995. Inspired by Buffett, he built CSI with a long-term mindset, focusing on acquiring and holding Vertical Market Software (VMS) companies. VMS refers to niche, industry-specific software, such as cemetery management systems, which often operate in smaller markets where a few players dominate, ensuring high margins and returns on capital.
CSI's business model is highly decentralized, with a tiny head office (less than 20 people) overseeing several operating units (e.g., Topicus, Harris, Vela). These units, in turn, push capital allocation decisions further down to their acquired companies. This structure, designed to minimize bureaucracy and foster autonomy in smaller teams, has allowed CSI to acquire over 1,000 companies. Leonard's approach to incentives focused on high Returns on Invested Capital (ROIC) (historically in the 30s, recently mid-20s), encouraging operating units to reinvest profits in new acquisitions or initiatives rather than upstreaming cash to avoid distorting bonus structures.
A remarkable aspect of CSI's history is its share count: it has issued zero new shares since its IPO, funding all acquisitions through cash flow and debt. This reflects a strong shareholder-friendly culture, though Leonard also expressed discomfort with buybacks due to information asymmetry. Executives are required to use 75% of their after-tax bonuses to buy CSI shares, which must be held for at least four years.
The main driver of the recent stock decline is the "AI narrative." Many fear AI could disrupt CSI's businesses, either by allowing companies to "vibe code" their own software, reducing the cost of building software, or by leading to "seat compression" where AI agents replace human users, decreasing the need for software licenses. However, CSI's defense highlights that 75% of its revenue comes from sticky, mission-critical *maintenance* contracts for essential services (like public transport or hospital IT), where switching costs are high and clients are risk-averse. Leonard also suggests AI might enhance existing roles rather than replace them, and internally, AI could boost efficiency, save costs (staff is 70% of expenses), and speed up acquisition sourcing.
Leonard has previously hinted at exploring investments beyond VMS, suggesting potential limitations in the core VMS market or a desire to allocate capital more broadly. An example was a large, "contrarian" deal in the thermal oil sector, which ultimately didn't materialize. While Mark Miller is the new CEO, with a long history at CSI, his ability to execute new strategic shifts outside VMS is a point of consideration for investors.
In terms of valuation, with the stock now 50% down from its highs, it's trading at significantly lower multiples than in previous years. Daniel's valuation, using a 12-13% top-line growth CAGR, slight margin expansion, and a 25x cash flow multiple, estimates a fair value of $2,300-$2,400 USD, suggesting a 12-13% internal rate of return (IRR). However, Sean notes that a 25x multiple isn't inherently cheap without significant growth, and questions whether the market is truly "dramatically overreacting" given the AI uncertainty and the shift in leadership.
Both hosts express cautious optimism. Daniel, while acknowledging CSI as a great company at a fair price, leans towards exploring smaller VMS "copycats" for potentially higher growth and agility. Sean agrees, suggesting a deeper dive into these spin-offs or similar companies before committing to a Constellation investment, especially given existing portfolio exposure to other acquirers like Berkshire and Transdigm.
