Stock split

“A proportional change to a company's number of shares that leaves each holder's ownership percentage unchanged.”

Why stock split matters to a first-time founder

A stock split changes the unit count and per-share figures without changing the company’s underlying value or each holder’s percentage ownership. It may make the quoted price more accessible or simplify trading. Private companies still need to update registers, option terms, contracts and authorised share details correctly.

Examples of stock split

In a 4-for-1 split, a founder’s 2,500 shares become 10,000. If the company was valued at $1 million before and nothing else changes, the founder’s total holding has the same value immediately after the split, while the implied value per share falls to one quarter of its previous amount.

Common misunderstanding

A stock split does not issue a founder a larger percentage of the company or raise new capital. It divides the same ownership into more units. It also differs from a stock dividend in legal and accounting form, even when both increase share counts, and from a reverse split, which consolidates shares.

When to use it

Use the term when explaining a proportional subdivision of every affected holding. Before approving one, check company law, constitutional documents, shareholder approvals, securities rules and how options or convertible instruments must adjust. State the ratio and effective date, then reconcile the cap table and statutory register after completion.
