Verisign, Inc. is an American company based in Reston, Virginia, that operates a diverse array of network infrastructure, including two of the Internet's thirteen root nameservers, the authoritative registry for the .com, .net, .web and .name generic top-level domains and the .cc country-code top-level domains, and the back-end systems for the .jobs and .edu sponsored top-level domains.

The company operates the authoritative registries for .com and .net under agreements with ICANN and the United States government, which makes it infrastructure rather than a conventional software business. Every .com domain in existence pays a wholesale fee, and the contract sets the terms under which those fees can rise, so revenue is close to a function of domain count and a regulated price. Operating costs barely move with volume, producing margins few businesses sustain. The risk is concentrated in contract renewal and regulatory review rather than competition. Headquarters are in Reston, Virginia.

If a meaningful share of your net worth sits in VRSN, concentration risk is the question. This calculator quantifies drawdown impact at 30 / 50 / 70%, and the trade-off between selling down (tax cost now) versus hedging (option premium drag), auto-filled with VRSN's option-implied volatility.
Example: 5,000 VRSN shares at $276.74 is a $1,383,700 position. A 30% drawdown costs $415,110; a 50% drawdown costs $691,850; a 70% drawdown costs $968,590. The calculator quantifies the trade-off between selling down (immediate capital-gains tax) and hedging (option premium drag) using VRSN's option-implied volatility and your cost basis.

Verisign equity questions
- How much VRSN stock is too much?
- There is no single threshold, but the larger the share of your net worth in one stock, the more a single bad year can set back your plans. The calculator above quantifies the drawdown impact at 30, 50, and 70 percent for your VRSN position and weighs selling down (which triggers capital-gains tax now) against hedging (which costs option premium).
- Does Verisign grant ISOs, NSOs, or RSUs?
- Equity compensation at Verisign typically takes the form of restricted stock units (RSUs). Restricted stock units are taxed as ordinary income when they vest.
