Definition
Dilution
Dilution is the reduction in existing shareholders' percentage ownership when a company issues new shares.
When a company raises capital through a fresh issue, ESOP grants, convertible notes or new rounds, the total share count rises, so each existing holder's slice of the company shrinks unless they buy more. Dilution affects both ownership percentage and earnings per share.
In the startup context, founders and early investors are diluted at every funding round; in listed companies, fresh equity issues dilute public shareholders. Anti-dilution clauses, pre-emptive rights and pro-rata rights are tools investors use to protect against unwanted dilution.
