A business valuation does not necessarily end once the enterprise value or equity value has been calculated. The next question is equally important: what exactly is being valued? A controlling interest and a minority interest in the same company can have materially different values.
A minority discount is generally applied after arriving at the equity value of a business. It reflects the reduced value of a shareholding that lacks the ability to influence key decisions affecting the company’s future and, ultimately, the economic benefits available to shareholders.
The most significant reason for applying a minority discount is the absence of control. A minority shareholder is typically unable to influence dividend policy, appoint or remove directors, approve major acquisitions or disposals, determine executive remuneration, alter the company’s strategic direction, or decide when the business should be sold. Even where the business performs well, the shareholder may have little influence over when, or even whether, profits are distributed. The value of a shareholding therefore extends beyond its proportionate claim on equity; it also depends on the rights attached to that ownership.
Liquidity is another important consideration. A minority interest in a private company is often significantly more difficult to sell than a controlling stake. The shareholder cannot control the timing or process of a sale and usually has a much smaller pool of potential buyers. In contrast, the holder of a controlling interest can initiate and manage a sale process that is likely to attract strategic buyers willing to pay for control.
Other factors may also justify a higher or lower minority discount. These include restrictive provisions in shareholders’ agreements, pre-emptive rights, drag-along and tag-along clauses, the size of the minority holding, board representation, voting thresholds, the quality of corporate governance, expected future distributions, and the likelihood of an exit event. Each valuation should therefore consider the specific rights and restrictions attached to the shareholding rather than relying solely on a standard percentage.
South African valuation practitioners commonly apply minority discounts as a separate adjustment to the equity value rather than to the enterprise value. The PwC Africa Valuation Methodology Survey also reflects this market practice and indicates that minority discounts applied in South Africa typically fall within a broad range of approximately 10% to 30%, depending on the facts and circumstances of the particular investment.

An interesting comparison can be drawn with listed companies. Individual shares traded on a stock exchange are, by their nature, minority interests. Their market prices therefore already reflect the characteristics of minority ownership, including the absence of control. However, listed shares benefit from a highly liquid market, which substantially reduces or eliminates the separate discount that would otherwise be associated with the difficulty of selling an interest in a private company.
This distinction also helps explain why takeover announcements and delisting offers often result in an immediate increase in the target company’s share price. An acquirer purchasing the entire business is buying control rather than a minority interest. The offer price therefore frequently includes a control premium, effectively removing the minority discount embedded in the pre-announcement share price. While not universal, this phenomenon is commonly observed in public market acquisitions and illustrates the economic value that control can add. The market is not simply revaluing the underlying business; it is recognising that ownership has changed from a minority position to one that carries the ability to control future decisions and unlock value.
