Deal Terms
Fully Diluted Shares
The total number of shares that would be outstanding if all convertible securities, options, and warrants were exercised.
Fully diluted shares represent the maximum number of shares that could be outstanding if every convertible security (SAFEs, notes, warrants, options) were converted or exercised. This count includes common stock, preferred stock, unexercised options (both vested and unvested), unissued option pool shares, and any other potentially dilutive instruments. Ownership percentages should always be calculated on a fully diluted basis to reflect true economic ownership.
In Practice
A company has 7M common shares, 3M preferred shares, 1.5M outstanding options (800K vested), and 500K unissued pool shares. Fully diluted count = 12M shares. A founder with 3M shares owns 25% fully diluted, not the 43% their common-only calculation might suggest.
Why It Matters
Calculating ownership on a fully diluted basis prevents founders and investors from overestimating their true economic stake. Cap table discussions should always use fully diluted numbers.
