How Do Share Premiums Work?

Summary

  • A share premium arises when a company issues shares at a price exceeding their nominal value, with the excess amount required to be recorded separately in a share premium account on the company’s balance sheet.
  • The nominal value of a share is its face value as recorded at Companies House, and shares can never be issued for less than this amount, as it represents the minimum amount shareholders must pay.
  • Funds held in the share premium account are subject to legal restrictions on their use, including restrictions on paying dividends, meaning they cannot be treated as freely distributable profits.
  • This article explains share premiums and their legal implications for company directors and shareholders operating in the UK.
  • LegalVision, a commercial law firm specialising in advising clients on corporate law and equity structuring, outlines how share premiums arise and what the share premium account means in practice.

Tips for Businesses

Set a low nominal value for shares when incorporating, such as £0.01, to minimise the minimum payment obligation on shareholders. Before issuing new shares to investors, conduct a company valuation to determine the appropriate issue price. Consider splitting shares before bringing in investors to simplify shareholding structures and avoid fractional shares.

When a company issues shares above their nominal value, the excess amount is called a share premium, and it carries specific legal obligations for how it must be recorded and used. This article explains share premiums, how they come about, and the legal implications of having a share premium account.

What is a Share Premium?

A share premium is the amount of money investors pay for a company’s shares that exceeds the nominal value of those shares. In other words, it is the difference between what investors pay for newly issued shares and the face value of the shares. The company records this excess amount separately from the share capital on its balance sheet.

Nominal vs Market Value

We define the nominal value of the shares as the face value of the share or the value as recorded at Companies House. When considering nominal value, it is important to note that:

  • often, for small businesses, the nominal value of your company’s ordinary shares is £1 because this was the default value when registering your company with Companies House. However, you can select a nominal value, such as £0.01 per share;
  • companies should not set a high nominal value, as this amount becomes the minimum amount that shareholders must pay for their shares; in other words, it is a debt that the shareholder owes to the company; and
  • later, after your company has generated revenue and become successful, the nominal value of your shares may be considerably less than the market value. 

Consider the following example.

FamCo Ltd

Suppose you and your sister start a company, FamCo Ltd. You transfer £5,000 to FamCo, and so does your sister. In exchange, each of you receives 5,000 shares. The nominal value of these shares would be £1 because 10,000 shares correspond to your company’s share capital of £10,000. 

Five years later, your friend approaches you and asks if he can invest in your company. They have £10,000 to invest. 

How Many Shares Would You Give Him? 

To answer this question, you need to know your company’s value. In practice, you would also want to know what sort of returns your investor was looking to gain, but this is a simplified example. 

To calculate your company’s value, you would need to conduct a valuation of your business. 

Understanding FamCo’s Share Premium 

Let us say you hire an accountant, and she values your company at £100,000. 

Given that your company is worth 10 times what it was (roughly speaking) when you incorporated it, you would probably want to receive 10 times as much per share. 

In other words, your shares would now be worth £10 (10 x £1). Therefore, a fair value for your buyer would be 1,000 shares (£10,000 / £10). 

From a legal perspective, the law requires you to distinguish between the price someone has paid for new shares issued in a company and the nominal value of these shares as recorded at Companies House. You cannot sell shares for less than their nominal value. However, if an investor cannot pay the price for the shares immediately, you can issue them with Partly Paid Shares.

Shares

In FamCo’s case, of the £10,000 given to FamCo in exchange for 1,000 shares, FamCo must use £1,000 to pay the nominal value of each share. This is because the nominal value must always be paid up on issued shares, subject to certain exceptions such as with Partially Paid Shares.

You must record the sale of the shares for an additional £9,000 in the share premium account.

This means the actual nominal value of your shares does not significantly matter as long as they are paid up to that amount. 

For instance, you could legally set the nominal value of each of your shares at £3.85943 per share. However, it is more straightforward and more conventional to deal with round numbers, such as increments of 10.

Regardless of the nominal value, you must always issue your shares for at least this amount. You cannot issue shares for less than this (though you could issue shares for non-cash consideration, such as for services rendered to the company).

Changing the Nominal Value of Shares

A company can change the nominal value of its shares when it splits them. A share split occurs when a company subdivides its existing shares. For example, a company could split 100 shares, each with a nominal value of £1 (i.e., a total nominal value of £100 for all shares), to 1000 shares, each with a nominal value of £0.10 (i.e., still a total nominal value of £100 for all shares). 

Companies often split shares when bringing in investors, and there are several reasons to consider doing so:

  • it ensures they can give an investor shares without involving fractional shares;
  • it is much easier to offer an investor a 33% stake in a company with thousands of shares instead of ten shares; and
  • if you plan to bring in investment to your company, splitting your shares keeps shareholdings as simple as possible.

Key Statistics

  1. 5.43 million: Private limited companies on the UK register at March 2025, all governed by Companies Act 2006 share premium rules on equity issuance.
  2. 77.6%: FTSE 350 companies that sought authority to disapply pre-emption rights in 2024-25, enabling faster share issues at a premium.
  3. £10.8 billion: Equity finance provided to smaller UK businesses in 2024, typically structured with new shares issued at a premium.

Key Takeaways 

A company share will be issued at a premium if the investor has paid the company more than the share’s nominal value. A company’s nominal share value is the price recorded at Companies House. This figure is often £1 (or £0.10) in practice. If a company has grown in value, it is common for the market value to exceed the nominal value. By law, you must record the difference between the price paid (the market value) and the nominal value and record this amount in the company’s share premium account. The effect is that the money raised cannot be used for certain things, like issuing dividends to shareholders.

Frequently Asked Questions 

What is a share premium? 

A share will be issued at a premium if it is issued at a price greater than its nominal value. The share premium is the difference between the amount paid and the share’s nominal value.

What is the nominal value of a share?

The nominal value of a share is its face value, which is recorded at Companies House.

Why would a company split its shares and how does this affect nominal value?

A share split subdivides existing shares into a greater number of shares with a proportionally lower nominal value, keeping the total nominal value the same. Companies often split shares before bringing in investors to avoid fractional shares and simplify shareholding structures.

Can a company issue shares for less than their nominal value?

No. You must always issue shares for at least their nominal value. The nominal value represents the minimum amount shareholders must pay for their shares, making it effectively a debt owed to the company that must always be paid up on issued shares.
