Imagine a candy store worth $1,000,000 to a buyer who purchases all of it. Now try to sell 49% of it. The intuitive price is $490,000. The market’s answer is almost always lower — sometimes far lower — and the reasons are structural, not personal.
The control discount
A 49% owner cannot set salaries, hire or fire management, decide distributions, sell the company, or stop the 51% owner from doing any of those things. The minority holder rides along with someone else’s decisions. Appraisers call the haircut for this a discount for lack of control, and in private-company valuation practice it commonly runs in the range of roughly 10–30% depending on the rights attached to the stake, the governance documents, and who the majority owner is.
The marketability discount
Separately, there is no ready market for a minority slice of a private candy store. Finding a buyer takes time; the buyer pool is thin (who wants to be locked in a partnership they don’t control?); and the sale itself may need the majority owner’s cooperation. The discount for lack of marketability reflects that illiquidity and, in appraisal practice, has often been observed in a similar broad range — and the two discounts compound rather than add.
The compounding math
Apply an illustrative 20% control discount and 25% marketability discount to the pro-rata $490,000: $490,000 × 0.80 × 0.75 = $294,000 — about 30% of the whole business’s value for 49% of its shares. The exact numbers vary with facts and appraiser judgment; the direction never does.
What changes the outcome
Rights, not percentages, drive value. Tag-along rights, board seats, veto rights over major decisions, put options, and drag-along protections can shrink the discounts; their absence widens them. A stake sold into an organized process — with verified buyers, disclosed pricing methodology, and custody settlement — typically fares better than one shopped cold.
