Shares portions refer to the portion of a company's issued share capital that is owned by an individual or entity. The term is commonly described as an ownership percentage or equity stake and can be expressed either as a number of shares or as a share of the total outstanding shares. A share portion is calculated by dividing the holder’s shares by the total outstanding shares, with adjustments for any dilutive securities such as stock options, warrants, or convertible debt.

In practice, share portions determine rights and claims within the company, including voting power, dividends, and distributions on liquidation, typically proportional to the ownership stake. Cap tables are used to track share portions for founders, investors, and employees, reflecting current ownership and potential future dilution. When new shares are issued, existing portions may be diluted unless protections such as pre-emption rights or anti-dilution provisions apply.

For startups, founders establish initial share portions to define ownership of the company, while investors purchase portions that represent a percentage of total equity, often with preferred terms. As employees’ options vest, new share portions are allocated, which can alter the overall distribution. Corporate actions such as share splits, mergers, or reorganizations can also adjust the appearance of share portions without changing the underlying ownership percentage.

Example: a company with 1,000,000 outstanding shares and an investor holding 100,000 shares has a 10% share portion. After a 2-for-1 split, the investor still holds 10% of the company, though the number of shares doubles. See also equity, cap table, fractional ownership.
