Warren Buffett’s Stake in VeriSign Reflects a Moat — But the Valuation Leaves Little Room for Error

Investors are paying a premium for stability, not growth or margin of safety. VeriSign (NASDAQ: VRSN) reported $1.6 billion in revenue and $826 million in net income in 2025 — solid figures for a company that operates the backbone of domain registration. The firm manages .com and .net domains under long-standing contracts with ICANN, a role that amounts to a legal monopoly. That control extends to two of the world’s 13 root servers, reinforcing an infrastructure moat that’s difficult to replicate. Warren Buffett’s Berkshire Hathaway owns a 9.8% stake, built over a decade, reflecting a classic value investor’s appetite for entrenched, cash-generating businesses. But the market is already pricing in permanence. With domain base growth projected at just 1.5% to 3.5% in 2026, expansion is modest. Meanwhile, the stock trades at a forward price-to-earnings ratio of 27.7 — richer than even Nvidia, at 21.5, despite Nvidia’s explosive growth trajectory. When a mature business commands a multiple typical of high-growth leaders, the margin for error vanishes. The cash flow is reliable. The position is defensible. But at current levels, the stock assumes no disruption, no regulatory shift, and no structural decline in domain reliance — a set of assumptions that leaves investors exposed if any of them break.
