Share Subscription Agreement in South Africa

What is a share subscription agreement?

A share subscription agreement is a contract under which an investor (the subscriber) agrees to subscribe for new shares to be issued by a company, and the company agrees to allot and issue those shares in exchange for the agreed subscription price. The defining feature is that the shares are created and issued by the company — they did not exist before. The subscription money therefore flows into the company as fresh capital, which is exactly why founders use a subscription to raise growth funding, bring in an investor, or recapitalise. This is fundamentally different from buying existing shares from a current shareholder (a share sale or share purchase agreement), where the price goes to the seller and nothing changes inside the company. Because new shares are issued, the existing shareholders are diluted — their percentage of the company drops unless they also subscribe. Under the Companies Act 71 of 2008, the issue of shares is a board act: section 38 lets the board resolve to issue shares, but only within the classes and number authorised in the company’s Memorandum of Incorporation (MOI) under section 36. A subscription agreement usually rides alongside a revised MOI and a shareholders’ agreement that fix the new investor’s rights.

Is a share subscription agreement legally binding in South Africa?

Yes — a share subscription agreement is binding as an ordinary contract, and the shares are validly issued once the company allots and issues them in compliance with the Companies Act. There is no statutory writing requirement, but the issue must clear several gates. First, the shares must already be authorised in the MOI (section 36); if not, the authorised shares must be increased — by a special resolution amending the MOI or, unless the MOI provides otherwise, by the board (section 36(2)–(3)). Where shares are issued without that authority or in excess of the authorised number, section 38(2) allows the issue to be retroactively authorised “in accordance with section 36” within 60 business days — by the same route, so the board can do it only where the MOI does not provide otherwise. Second, the board must resolve to issue the shares (section 38) and determine adequate consideration before issue under section 40 of the Companies Act 71 of 2008 — and where the price is an instrument whose value the company can only realise later, or an agreement for future services, benefits or payment, section 40(5) requires the shares to be issued at once and transferred to an independent stakeholder (such as an attorney, notary or escrow agent), held under a written stakeholder agreement, and later transferred to the subscriber in accordance with that agreement (as amended with effect from 27 December 2024). Third, existing shareholders’ pre-emptive rights under section 39 must be respected, and where shares are issued to a director, prescribed officer or a related person, a special resolution may be required under section 41. The powers to authorise and issue shares are also subject to the directors’ fiduciary duties: in CDH Invest NV v Petrotank South Africa (Pty) Ltd [2019] ZASCA 53 the Supreme Court of Appeal held a directors’ round-robin resolution increasing the authorised shares invalid because the directors had misrepresented its real purpose — conduct that “did not comport to the standard of good faith required of directors in terms of s 76(3)” (para 24). The High Court had also found the power was not used for a proper purpose; the SCA agreed in essence but decided the appeal “on a somewhat narrower basis” (para 13). Importantly, most breaches do not make the issue automatically void: under section 218(1), unless the Act specifically declares it void, nothing in the Act renders void an agreement or resolution that is prohibited, voidable or may be declared unlawful under the Act until a court declares it so, so a wronged shareholder must approach the court. The exception is an issue of unauthorised shares or in excess of the authorised number: if the resolution to authorise it retroactively is put to a vote and not adopted, section 38(3) makes the issue a nullity to the extent that it exceeds any authorisation, the company must return the fair value of the consideration with interest, and the share certificate and register entry are void.

“The board of a company may resolve to issue shares of the company at any time, but only within the classes, and to the extent, that the shares have been authorised by or in terms of the company’s Memorandum of Incorporation, in accordance with section 36.”

Companies Act 71 of 2008, ss 38–41 (issue of shares, consideration, pre-emption, shareholder approval)

“If a private company proposes to issue any shares … each shareholder of that private company has a right, before any other person who is not a shareholder of that company, to be offered and, within a reasonable time to subscribe for, a percentage of the shares to be issued … A private or personal liability company’s Memorandum of Incorporation may limit, negate, restrict or place conditions upon the right set out in subsection (2)”

Companies Act 71 of 2008, s 39 (subscription of shares / pre-emptive right of existing shareholders)

“Their conduct did not comport to the standard of good faith required of directors in terms of s 76(3) of the Act … Directors act beyond their authority when they act in breach of their duty to perform with good faith and in the interests of the company … I accordingly find that the round robin resolution signed on 31 March 2014 was invalid.”

When you need a Share Subscription Agreement

An investor, venture-capital fund or strategic partner is putting fresh capital into a company in exchange for newly issued shares, and the money is meant to fund the business rather than buy out an existing owner.
A founder is raising a seed or growth round and needs to record the valuation, the number and class of new shares, the subscription price, and the conditions on which the money is released to the company.
A company is recapitalising or converting a shareholder loan or convertible instrument into equity, so that new shares must be authorised, issued and the existing shareholders’ pre-emptive rights addressed (the statutory right in section 39 does not apply to shares issued in terms of conversion rights, but the MOI or a shareholders’ agreement may).
New shares are being issued to a director, prescribed officer or a related or inter-related person, triggering the section 41 special-resolution requirement and the need to manage dilution of the other shareholders.
A subscription is being done alongside an existing-share sale in the same deal (a combined sale-and-subscription), so the agreement must keep the “new shares” and “existing shares” legs and their different tax and Companies Act consequences distinct.

What a Share Subscription Agreement should contain

Subscription, allotment and the new shares

The core obligation: the subscriber subscribes for a stated number and class of new shares, and the company undertakes to allot and issue them and update the securities register. Specify whether the shares are ordinary or a preference/special class, and confirm they are (or will be) authorised in the MOI under section 36.

Subscription price, consideration and payment mechanics

Set the subscription price per share and in total, when and how it is paid, and that it constitutes adequate consideration as the board must determine under section 40 before issue. If any part is a deferred-value instrument or a promise of future services, benefits or payment, build in the section 40(5) mechanism: the shares are issued at once and transferred to an independent stakeholder (an attorney, notary or escrow agent) under a written stakeholder agreement, and released to the subscriber as the value is realised or the obligations are performed.

Conditions precedent

List the conditions to be met before the issue completes — board resolution to issue, MOI amendment to create/authorise the shares, any section 41 special resolution, regulatory or Competition Act approval, financier consents, and satisfactory due diligence. State who must fulfil each and the long-stop date if they are not met.

Pre-emptive rights and waivers (section 39)

Address the existing shareholders’ statutory pre-emptive right to be offered the new shares first. Either confirm the right has been complied with or obtain written waivers, and check whether the MOI has limited, varied or excluded section 39 — pre-emption is the most commonly overlooked validity gate on a new issue.

Warranties and representations

The company (and often the founders) warrant the state of the business the investor is paying for — share capital and cap table, authorised and issued shares, financials, tax, litigation, material contracts, compliance and that the shares will be issued free of encumbrances. Warranties on a subscription protect the value of the new money going into the company.

Use of funds and post-completion obligations

Because the subscription money funds the company, investors usually restrict its application (working capital, a specific project, repaying a defined liability) and add reporting, information and milestone covenants. Tie completion to delivery of the updated share certificate, securities register entry and (where relevant) the new MOI and shareholders’ agreement.

Shareholders’ agreement and MOI alignment

The subscription should dovetail with a shareholders’ agreement and the MOI dealing with the new investor’s rights — board representation, reserved matters, anti-dilution, drag/tag, dividend and exit rights. Under section 15(7) the shareholders’ agreement must be consistent with the MOI and the Act, or it is void to the extent of the conflict.

Section 41 special resolution (issues to related persons)

Where the new shares go to a director, prescribed officer, a related or inter-related person, or their nominee, confirm the section 41(1) special resolution has been (or will be) passed — unless an exemption applies (issue under an underwriting contract, in exercise of pre-emptive rights, or pro rata to existing holdings under section 41(2)).

Common South African pitfalls

Issuing shares that are not authorised in the MOI. The board can only issue shares within the classes and number authorised under section 36. If the authorised shares are insufficient they must first be increased — by special resolution amending the MOI or, unless the MOI provides otherwise, by the board (section 36(2)–(3)) — and an issue made without that authority can be retroactively authorised only in accordance with section 36, within 60 business days (section 38(2)). In CDH Invest v Petrotank [2019] ZASCA 53 a board resolution increasing the authorised shares was held invalid because the directors misrepresented its real purpose, falling short of the good faith section 76(3) requires.
Ignoring existing shareholders’ pre-emptive rights. Section 39 gives existing shareholders a first right to subscribe pro rata for a new issue (the default for private companies under s 39(2)), unless the MOI varies it. Issuing to an outside investor without offering or obtaining waivers from existing holders exposes the issue to challenge and the directors to a proper-purpose attack.
Missing the section 41 special resolution. Where new shares are issued to a director, prescribed officer, a related or inter-related person, or their nominee, a 75% special resolution is required under section 41(1) unless an exemption in s 41(2) applies. A missing s 41 resolution is a recurring defect in founder and management share issues.
Getting the consequences of a defective issue wrong. The general rule is section 218(1): unless the Act specifically declares it void, nothing in the Act renders void an agreement or resolution that is prohibited, voidable or may be declared unlawful under the Act until a court makes a declaration to that effect — so for most defects an aggrieved shareholder must actually litigate. But an issue of unauthorised shares, or in excess of the authorised number, is different: if the retroactive resolution under section 38(2) is put to a vote and not adopted, section 38(3) makes the issue a nullity to the extent that it exceeds any authorisation, the company must return the fair value of the consideration with interest, the certificate and register entry are void, and a director who knowingly failed to vote against the issue is personally liable (section 77(3)(e)(i)). Financial assistance under ss 44–45 is likewise expressly void to the extent of non-compliance. Do not assume an irregular issue is safe; it remains vulnerable to being set aside.
Confusing a subscription with a sale of shares — or with financial assistance. A subscription raises new capital and dilutes; a sale transfers existing shares with no dilution. And if the company itself funds the subscriber’s acquisition of shares (a loan, guarantee or security), section 44 financial-assistance requirements (special resolution, solvency and liquidity test, fair-and-reasonable terms) are triggered and non-compliance is void to that extent.
Leaving consideration and completion mechanics loose. The board must determine adequate consideration before issue (section 40), and where the price is a deferred-value instrument or a promise of future services, benefits or payment, section 40(5) requires the shares to be transferred to an independent stakeholder under a written stakeholder agreement until the value is realised or the obligations are performed. Failing to align payment, the securities-register entry, the share certificate and the updated MOI/shareholders’ agreement leaves the investor without clean title to the new shares.

Frequently asked questions

What is the difference between a share subscription and a share sale in South Africa?

In a share subscription, the company issues new shares to the subscriber and the money goes into the company as fresh capital, diluting existing shareholders. In a share sale, an existing shareholder transfers shares they already own and the money goes to that seller, with no change to the company’s share capital. Subscriptions raise capital; sales change ownership.

Is a share subscription agreement legally binding without being notarised or registered?

Yes. A share subscription agreement is binding as an ordinary written contract — South African law imposes no notarisation or registration requirement for it to be valid. What must be done is the corporate issue itself: the board must resolve to issue the shares, the shares must be authorised in the MOI, and the securities register must be updated under the Companies Act 71 of 2008.

Do existing shareholders have to be offered the new shares first?

Usually yes. Section 39 of the Companies Act gives each existing shareholder of a private company a pre-emptive right to be offered, before outsiders, a pro-rata share of any new issue equal to their existing voting power. The MOI can limit, vary or exclude this right, so it must be checked — and where it applies, existing shareholders should be offered the shares or sign waivers.

When does a share subscription need a special resolution of shareholders?

A special resolution (75%) is required under section 41(1) when the new shares are issued to a director, prescribed officer, a person related or inter-related to the company or a director, or a nominee of any of them. Exemptions in section 41(2) include issues under an underwriting contract, in exercise of pre-emptive rights, or in proportion to existing holdings. Increasing the authorised shares by amending the MOI also needs a special resolution, unless the board may do it under section 36(3) because the MOI does not provide otherwise.

Who has to approve the issue of new shares — the board or the shareholders?

The board approves and resolves to issue shares under section 38, but only within the classes and number authorised in the MOI under section 36. Shareholders are involved where the authorised shares must be increased and the MOI does not let the board do it under section 36(3) (a special resolution to amend the MOI), or where section 41 requires a special resolution because the shares go to a director, prescribed officer or related person.

What consideration can a company accept for new shares?

Under section 40, the board must determine adequate consideration before the shares are issued — it may be cash, assets, services or other value the board judges adequate. Where the consideration is a deferred-value instrument or an agreement for future services, benefits or payment, section 40(5) (as amended with effect from 27 December 2024) requires the shares to be issued immediately and transferred to an independent stakeholder, held under a written stakeholder agreement, and later transferred to the subscriber in accordance with that agreement.

Are shares void if the company does not follow sections 38 to 41?

Not automatically — with one important exception. Section 218(1) of the Companies Act provides that, unless the Act specifically declares it void, nothing in the Act renders void an agreement or resolution that is prohibited, voidable or may be declared unlawful under the Act, unless a court has made a declaration to that effect. So most defects in a share issue stand until challenged and set aside by a court. The exception is section 38(3): where shares were issued without authorisation under section 36 or beyond the authorised number, and the resolution to authorise the issue retroactively is put to a vote and not adopted, the issue is a nullity to the extent that it exceeds any authorisation and the company must return the fair value of the consideration, with interest. Financial assistance under sections 44 and 45 is likewise void to the extent of non-compliance.

Does a share subscription dilute the existing shareholders?

Yes, unless they also subscribe. Because a subscription creates and issues new shares, the total number of shares increases, so each existing shareholder’s percentage falls unless they take up their pro-rata pre-emptive entitlement under section 39. Investors and founders often deal with this through anti-dilution and pre-emption provisions in the subscription and shareholders’ agreement.
