Knowledge Base: How to process a share split on FounderCatalyst

What is a share split?

A share split is an action that increases the number of a company’s shares by dividing existing shares into multiple new ones. The total value of a shareholder's investment remains the same — only the number and nominal value of each share changes.

Example: If a company carries out a 1:10 share split, every 1 share becomes 10 shares. A holding of 100 shares becomes 1,000, but the total value remains unchanged.

Why carry out a share split?

UK companies may carry out a share split to:

• Reduce the nominal value per share

• Simplify investment terms or prepare for a funding round

• Make share ownership more accessible

• Present a cleaner, more investor-friendly cap table

Note: After a share split, you must file an SH02 form with Companies House to update your company's official records. This can be done before or after updating the share split on FounderCatalyst — but it must be filed to remain compliant. View our SH02 filing guide
