The Importance of Fully Diluted Shares

Implications for Investors

Fully diluted shares give investors insight into the potential future dilution of their equity stakes. This can be crucial for decision-making, affecting valuations, earnings per share (EPS), and voting power.

Calculating Fully Diluted Shares

Common Sources of Dilution

Total Shares Outstanding:

$$ 1,000,000 + 100,000 + 50,000 + (10,000 \times 2) = 1,180,000 $$
