How do I change the share structure of a UK company?
A UK limited company can change its share structure by issuing new shares, creating new share classes, changing share rights, subdividing or consolidating shares, or reducing its share capital.
The correct procedure depends on the type of change. The company may need director approval, shareholder resolutions, amended articles and specific Companies House filings.
A share structure describes:
Changing ownership through a simple transfer does not usually change the total share capital, but issuing or cancelling shares does.
Common reasons include:
The directors should identify the commercial purpose before selecting the legal process.
Start by reviewing the company’s articles and any shareholders’ agreement.
Check:
The articles may need to be amended before the proposed structure can be implemented.
A company may change its structure in several ways.
The company can allot additional shares to existing or new shareholders.
This increases the number of issued shares and may dilute existing owners. Form SH01 must normally be filed with Companies House within one month.
A shareholder can transfer shares to another person.
This changes ownership but does not increase or reduce the company’s total issued share capital. The transfer is recorded in the register of members and reported through the confirmation-statement process.
The company may create classes such as:
The class rights must be clearly defined. The articles may need to be amended and form SH08 may be required to notify the class name or designation.
The company may vary the voting, dividend, capital or redemption rights attached to an existing class.
Approval from the affected shareholders may be required. Form SH10 is used to notify Companies House of a variation of rights attached to shares.
A subdivision divides each existing share into several shares with a lower nominal value.
For example, one £1 share could become 100 shares of £0.01 each.
The overall nominal share capital remains the same, but the company has more shares. Form SH02 is generally used to report the change.
A consolidation combines several shares into a smaller number of shares with a higher nominal value.
For example, 100 shares of £0.01 each could become one share of £1.
The total nominal capital normally remains unchanged. This is also generally reported using form SH02.
The company may change the name or designation of an existing class, for example from ordinary shares to A ordinary shares.
The company must ensure that the redesignation is properly authorised and does not improperly change class rights. Relevant share-class forms and an updated statement of capital may be required.
A private company may reduce its share capital using an approved legal procedure, commonly supported by a solvency statement or court order.
This can involve:
A capital reduction requires shareholder approval and form SH19, together with the required supporting documents.
A company may purchase its own shares and then cancel them or, where permitted, hold them as treasury shares.
Buybacks involve strict rules relating to:
Professional advice is usually appropriate.
Depending on the change, the company may need:
A special resolution normally requires at least 75% approval. The articles may impose additional requirements.
The articles should accurately state the rights and restrictions applying to each class.
If they are amended, the company must normally send Companies House:
These documents must generally be filed within 15 days.
Once approval has been obtained, the directors should formally implement the change.
This may involve:
The board minutes should clearly describe what was approved and when the change took effect.
The company may need to update:
Old share certificates should be cancelled and replacement certificates issued where appropriate.
The form depends on the transaction. Common examples include:
Additional resolutions, amended articles, solvency statements or statements of capital may also be required.
New share allotments must normally be reported within one month. Many other share-structure changes must be reported within 21 days.
Possibly. The company should reassess its people with significant control after changing the structure.
A person may qualify as a PSC if they:
PSC changes must normally be reported to Companies House within 14 days.
Yes. Tax consequences may arise when:
A company-law change that appears simple can produce Capital Gains Tax, Income Tax, employment-related securities, Stamp Duty or Corporation Tax issues.
Not automatically.
Subdividing 100 shares into 1,000 shares does not itself make the company more valuable. It only divides ownership into smaller units.
Issuing shares to an investor may increase the company’s resources, but it can also dilute the ownership percentages of existing shareholders.
Before making the change:
A UK company can change its share structure in several ways, but each method has different approval, documentation and filing requirements.
Simple changes may be managed through resolutions and Companies House forms, while new share classes, buybacks, capital reductions and changes to class rights often require professional legal and tax advice.
