Shares outstanding represent the total number of a company's shares currently held by its shareholders, including promoters, institutional investors, and public investors. The figure is important for understanding a company's ownership structure and is used to calculate its market capitalisation by multiplying the number of outstanding shares by the current share price. Changes in shares outstanding can result from corporate actions such as stock splits, bonus issues, rights issues, buybacks, or new share issuance. Investors may also consider this figure when comparing companies by size and evaluating their position within major market indices.
