Is a 25% shareholding worth 25% of the company?

The short answer, explained

Multiplying the value of all the shares by the percentage held gives the pro-rata value. It is a useful and necessary calculation, and in some situations it is the final answer. It is not automatically the final answer, because a parcel of shares is a different asset from the company as a whole.

Two questions sit side by side. The first is: what is the whole company's equity worth? The second is: what is this particular holding worth, given what it allows the holder to do and how easily it could be sold? A valuation must say which question it answers. Where the instructions or an agreement settle the second question in advance, for example by requiring a straight proportion of equity value, the valuer follows them.

This page explains how to tell which situation applies. For a deeper look at how valuers analyse control and marketability adjustments when they are relevant, Oliver Group, the Valuo practice for restructures, tax and buyouts, publishes a guide to minority interest discounts.

Start with the equity value of the whole company

Before any question about a holding, the company's equity value must be established. That usually means valuing the operating business and then adjusting for surplus cash, borrowings and debt-like items. Our guide to enterprise value vs equity value explains that bridge.

Check also exactly what is being valued. Shares in a company, units in a unit trust and an interest in a partnership carry different rights. Our guide on business, shares or units covers that step. If the holder also has a loan to or from the company, value it separately from the shares; see shareholder loans.

Read the documents that define the holding

The rights attached to a parcel of shares come from documents, not from the percentage. A valuer will ask for:

• The constitution, or the replaceable rules if there is none. Under section 140 of the Corporations Act 2001, these operate as a contract between the company and its members. They set out share classes, voting, dividend rights, transfer restrictions and pre-emptive rights.
• Any shareholders agreement. This may add veto rights, board appointment rights, drag-along and tag-along rights, exit triggers and a valuation clause.
• The share register and any class rights. Different classes can carry different rights to vote, to dividends and to capital, so equal percentages do not always mean equal value.
• The company's dividend history and the minutes, which show how decisions are made in practice.

Agreed valuation clauses can override the analysis

A shareholders agreement may state how a departing shareholder's interest is to be valued. A clause might require market value of the shares as a whole divided pro rata, market value of the specific parcel, a formula, or a price fixed by an independent valuer on stated assumptions.

If the clause requires a pro-rata share of total equity value, the valuer should not then apply a minority adjustment the clause excludes. If it requires the market value of the parcel itself, the holding's rights become central. If the wording is ambiguous, the valuer should not quietly choose an interpretation that decides someone's entitlement. The parties should obtain legal advice and give the valuer clear written instructions. Oliver Group's guide to buy-sell valuation clauses covers drafting choices for lawyers.

Control: what the holding can and cannot do

Voting power under the Corporations Act 2001 helps frame what a holding can achieve:

• A special resolution, needed for example to modify the constitution, must be passed by at least 75 per cent of the votes cast (sections 136(2) and 250MA). A holder of more than 25 per cent of the votes cast can block one. A holder of exactly 25 per cent cannot do so alone if every other member votes in favour.
• Members holding at least 5 per cent of the votes can require the directors to call a general meeting (section 249D).
• Under the replaceable rule for proprietary companies, a director can be removed by resolution of the members (section 203C). A company's constitution may change this.

Those statutory points are only part of the picture. A shareholders agreement can give a minority holder a board seat or a veto over specified decisions, which can materially change the analysis. Conversely, a holder with no board seat, no say on dividends and no ability to force a sale has less influence than the percentage suggests.

Liquidity: can the holding be sold, and to whom?

A minority parcel in a private company has no public market. Pre-emptive rights may require it to be offered first to the other shareholders. The constitution may allow the directors to decline to register a transfer. A buyer of the parcel would take on the same constraints.

On the other hand, a tag-along right, a put option or an agreed exit mechanism can give the holder a clear path to cash. Where that path exists and is priced by reference to total equity value, the gap between pro-rata value and parcel value can narrow or disappear.

Why a discount is never automatic

A discount is not a fixed step that follows from holding less than half the shares. It is a conclusion that must be justified by the specific rights, restrictions and basis of value. Three points matter:

1. The basis of value. Market value of the parcel, fair value under an agreement and a court-ordered purchase can lead to different treatments. If the purchase is ordered by a court in an oppression proceeding under sections 232 and 233, the court's orders and reasons govern the approach. Get legal advice on which basis applies.
2. No double counting. A risk already reflected in the earnings, the capitalisation rate or a cash flow forecast should not be deducted again as a separate discount.
3. Evidence, not habit. A percentage copied from another matter is not evidence about this holding. If an adjustment is made, the report should say what it responds to and why its size is supportable.

Worked example (hypothetical)

This example is hypothetical, with round numbers, to show the steps only.

The $500,000 is arithmetic, not yet a conclusion. What happens next depends on the documents:

• If the shareholders agreement requires a pro-rata share of total equity value, the answer is $500,000, and no minority adjustment is made.
• If the agreement requires the market value of the parcel itself, the valuer analyses the holding's rights. In this example, assume one class of ordinary shares, no board seat for the 25 per cent holder, pre-emptive rights in favour of the other shareholders and no put option. Those facts are relevant to whether the parcel would attract less than $500,000 from a hypothetical buyer, and the report must explain any adjustment and its basis.
• If the agreement is silent or unclear, the parties need legal advice and agreed written instructions before the valuer can finalise the answer.

Decision table

No single row decides the answer. The table is a way to organise the documents before speaking to a valuer and a lawyer.

Limitations

This page is general information about valuation reasoning, not legal advice. It does not interpret any particular constitution or agreement, and it does not cover the approach a court may take in an oppression or family law proceeding, which depends on the facts and the court's orders. It does not address units in trusts or partnership interests in detail, and it does not deal with tax on a share transfer. Where a transfer is between related parties, a market valuation may be required for tax purposes; ask your tax adviser.

Next steps

• Gather the constitution, any shareholders agreement, the share register and the last three years of financial statements.
• Ask your lawyer what basis of value the agreement requires, and record it in writing.
• Use the enterprise-to-equity value calculator to understand the whole-company figure before discussing the holding.
• If a buyout is likely, read preparing for a shareholder buyout. Oliver Group, the Valuo practice for restructures, tax and buyouts, prepares valuations of shareholdings on agreed instructions.
