What is a Share Subscription Agreement?

In Short

  • A Share Subscription Agreement (SSA) formalises investment terms between a startup and an investor.

  • It details share quantity, price, type, and may include warranties to protect the investor.

  • Early-stage startups might opt for a simpler subscription letter if investors don’t require warranties.

Tips for Businesses

Seek legal advice when drafting an SSA to ensure clarity and limit potential liabilities. For early-stage investments, consider using a simpler subscription letter if investors aren’t requesting warranties. This approach can streamline the process and reduce administrative complexity.

If your startup is raising capital, you will need several documents before the money reaches your company’s bank account. A share subscription agreement is one document you may require if you are raising capital in a priced round. Although not every raise requires this agreement, if a company is issuing shares at an agreed valuation and price per share, a subscription agreement will be required. It is essential for founders to understand when it is required and what the agreement entails.

Where Does a Share Subscription Agreement Fit Into the Capital Raise?

When raising capital to get your startup off the ground, the Company and the investor will need to agree on a valuation for the Company prior to issuing any shares. The valuation will help determine the price being paid per share by the investor. If you cannot agree to a valuation for the Company, you may consider pivoting to a Simple Agreement for Future Equity or Convertible Note round.

If you are at the stage where you are looking to finalise your investment terms in a legal document, you have likely found a potential investor and wooed them with your pitch. At this stage, it is common to use a term sheet to negotiate the key terms of the deal between you and your investor. The term sheet is generally non-binding; however, seeking legal advice before signing a term sheet is highly recommended because the formal legal documents are drafted based on these terms.

Another step to consider before you put pen to paper on the legal documents is to generate a capitalisation table for your startup. A capitalisation table sets out the ownership percentage of each shareholder once the capital raise is complete. Once you and your investor have signed a term sheet and you are aware of your company’s share capital structure upon completion of the raise, you can formalise the next phase through both:

  • a shareholders’ agreement (if there is not already one in place); and
  • a share offer document, which can range from a simple share issue form to a share subscription agreement for more complex deals.

A subscription agreement is just one type of share offer document.

What Goes Into a Share Subscription Agreement?

A share subscription agreement sets out the key terms decided between your company and the investor and will specify:

  • the company issuing the shares;
  • the investor purchasing the shares;
  • how many shares the startup is issuing;
  • if the shares are subject to any conditions, such as vesting;
  • the class of those shares;
  • the subscription price for those shares;
  • when/how the startup will issue the shares; and
  • any conditions that the company must fulfil before the investor pays the money to the company.

Additionally, a share subscription agreement will typically include warranties from the company, as well as from the founder. These statements of fact pertain to the company, its business, and the shares being issued.

These warranties are for the benefit of the investor – they essentially help them understand what they are getting themselves into without requiring extensive due diligence. The warranties can include statements to the effect that:

  • all information the company or founder (as applicable) supplied is accurate and complete in all material respects;
  • the company or founder (as applicable) is not aware of any matters that present a litigation risk; and
  • the company possesses all intellectual property rights necessary to conduct its business.

The type of information that a company or founder might be required to provide to an investor, along with a representation or warranty, is typically provided in a Virtual Data Room.

Warranty

If a warranty proves to be incorrect, an investor could bring a claim against the company or the founder (as applicable) for damages they suffer as a result of the warranty being incorrect.

Especially as deal sizes grow, investors will want more warranties to give them greater comfort and reduce the risk they are taking, while companies will want to offer fewer warranties, thereby exposing themselves to less risk. 

As warranties can be so extensive, companies will usually seek certain limitations in respect of their potential liability for breach of warranty. It is not uncommon to see a limited claim period of:

  • between 12-24 months. This means the investor must bring a claim for breach of warranty within that limited period of time after being issued its shares; and
  • a maximum claim amount. This means the investor can only make a claim against the company or the founder, as applicable, for a maximum agreed-upon amount.

In early-stage investments, founders are often asked to provide warranties. These are typically more limited (in both number and scope) than company warranties, and the maximum claim amount is usually significantly lower.

When Would a Share Subscription Agreement be Necessary?

As mentioned above, a share subscription agreement is just one type of share offer document. If your investor has not requested a share subscription agreement, it would not be in the company’s interest to offer this up. 

An alternative is a share offer or share subscription letter. This document is concise, outlining the key terms and mechanics of the investment. However, it does not contain the company or founder warranties. Therefore, you get all the upside from the additional investment without the potential downsides associated with guarantees and liabilities. Instead, the investor must conduct their own due diligence

A share offer or share subscription letter is commonly used in seed or series A rounds when raising from family and friends or angel investors in a priced round. Venture capital (VC) investors are generally less involved in later rounds. If you are raising funds from a venture capitalist, they will likely insist on a share subscription agreement containing detailed representations and warranties from the Company and its founders.

When contemplating a raise, it is always beneficial to seek legal advice or drafting assistance from a startup lawyer to ensure you get the right documents in place.

Issuing Further Capital and Anti-Dilution Rights

If you have investors coming on early in your startup’s life, you may want to guarantee your rights to issue further capital. On the other hand, investors may want to ensure that their level of control within the company is not diminished unilaterally over time. So, you should prioritise addressing these competing needs. 

One option is to cover these details in a shareholders’ agreement. However, you want to ensure that your business plan and your relationship with members and directors are not impeded by your desire to issue capital via successive share subscription agreements. 

Instead, your collective corporate governance documents should facilitate the growth of the company in line with members’ wishes. 

What Comes Next?

Once parties sign the share subscription agreement, the investor and company must follow the investment procedure set out in the document, namely:

  • company/board (as required) will pass a resolution approving the issuance of new shares;
  • investor will pay the subscription money;
  • company will issue the investor with a share certificate; and
  • company will update its Members Register and notify ASIC of the new shareholder and its shareholding.
