A control premium refers to the additional value a buyer pays to acquire a controlling interest in a business above the value of a non-controlling (minority) interest on a per-share basis. In business valuation, control premiums reflect the economic advantage of control: the ability to direct operations, set compensation, declare dividends, make acquisitions, and determine the timing of a sale. Sofer Advisors, a nationally recognized business valuation firm, applies control premiums and discounts with precision across M&A valuations, shareholder disputes, estate and gift tax engagements, and buy-sell agreement analyses.
Control premium is one of the most consequential and most frequently debated concepts in business valuation. Apply it incorrectly, and the value conclusion can be millions of dollars too high or too low. In M&A negotiations, understanding control premium helps both buyers and sellers price transactions fairly. In shareholder disputes, the presence or absence of a control premium can be the difference between settlement and litigation. In estate planning, applying or omitting a control premium and its inverse, the DLOC, affects the taxable value of interests transferred to heirs. Every business owner and attorney who works with business valuations needs to understand when and why control premiums apply.
Key Takeaways
- A control premium is the percentage by which the per-share price of a controlling interest exceeds the per-share price of a minority interest in the same company.
- Control premiums in US M&A transactions have historically averaged 20%-40% above the pre-announcement minority trading price, based on data from transactions tracked by BVR and Mergerstat.
- The discount for lack of control (DLOC) is the inverse of the control premium and is applied in minority interest valuations to reduce the controlling interest value to a minority interest value.
- Whether a control premium applies, and its size, depends on the nature of the interest being valued, the purpose of the valuation, and whether the value conclusion is on a controlling or minority basis.
- Control premiums are not appropriate in all valuation contexts; their application in estate tax and marital dissolution cases varies by jurisdiction and standard of value.
What Is a Control Premium and Why Do Buyers Pay It?
A control premium is the additional amount a buyer pays, on a per-share basis, to acquire a controlling interest (generally more than 50% of voting shares) compared to what a minority share of the same company would trade for in the market. The premium reflects the concrete economic advantages that come with control:
A controlling interest holder can direct management and operational strategy, set the compensation levels for owners and key employees, determine the timing and amount of distributions and dividends, approve or block acquisitions, divestitures, and capital expenditures, negotiate and approve the terms of a sale or merger, and access the company’s cash and assets through legitimate management decisions.
A minority interest holder has none of these powers. A minority investor in a private company cannot force a sale, demand a dividend, or change management. The economic disadvantage of that powerlessness is reflected in a lower per-share value for minority interests.
Control premiums are most visible in public company M&A transactions, where the buyer’s offer price can be compared directly to the target’s pre-announcement stock price. Historical studies by Mergerstat and BVR document control premiums paid in thousands of US transactions, providing the empirical foundation for estimating control premiums in private company valuations.
How Is a Control Premium Measured?
In practice, control premiums are measured using two approaches:
The direct market approach compares the acquisition price paid for a controlling interest to the market price of the target’s stock in the period before the acquisition announcement. The control premium is:
Control Premium = (Acquisition Price Per Share / Pre-Announcement Market Price Per Share) – 1
For example, if a company’s stock trades at $20 per share before a takeover announcement and the acquirer pays $28 per share, the control premium is 40%. Mergerstat data shows median US control premiums in the 25%-35% range across most industries, with higher premiums in sectors with strong strategic buyer competition.
The indirect approach, used for private companies that lack publicly observable minority prices, derives the control premium from the relationship between the guideline public company (GPC) trading multiples and the transaction multiples in the guideline transaction method. GPC trading multiples reflect minority, marketable values; transaction multiples reflect controlling, marketable values. The difference between the two provides an implied control premium applicable to private companies in the same industry.
What Is the Discount for Lack of Control (DLOC)?
The discount for lack of control (DLOC), also called the minority interest discount, is the inverse of the control premium. It converts a controlling interest value into a minority interest value. The formula is:
DLOC = 1 – [1 / (1 + Control Premium)]
For a 30% control premium, the DLOC = 1 – [1 / 1.30] = 23.1%.
The DLOC is applied when the interest being valued is a minority interest and the valuation method used, such as a DCF or market multiple approach, inherently produces a controlling interest value. Because most income approach and market approach methods reflect the value of the entire enterprise (which is effectively a controlling value), a DLOC must be applied to convert that conclusion to a minority per-share value when the subject interest is less than controlling.
| Step | Example |
|---|---|
| Enterprise Value (Controlling Basis) | $10,000,000 |
| Shares Outstanding | 1,000,000 |
| Per-Share Controlling Value | $10.00 |
| Control Premium Applied (35%) | N/A |
| DLOC Applied (26%) | ($2.60) |
| Per-Share Minority Value | $7.40 |
What Is the Discount for Lack of Marketability (DLOM) and How Does It Interact?
The discount for lack of marketability (DLOM) is a separate adjustment that reflects the illiquidity of a private business interest relative to a publicly traded stock. Even a controlling interest in a private company takes 6-18 months to sell; a minority interest may be even harder to sell and may require a larger DLOM.
The DLOC and DLOM are applied sequentially, not additively:
- Start with enterprise value (controlling, marketable basis from income/market approach)
- Apply DLOC to convert to minority, marketable value
- Apply DLOM to convert from marketable to non-marketable (private company) value
The sequence matters because applying both discounts as additive percentages overstates the discount. Research from Stout, Duff & Phelps (Kroll), and academic sources supports DLOM ranges of 15%-35% for typical private company minority interests, depending on size, earnings history, and the nature of the interest. If you need a defensible DLOC and DLOM analysis for a minority interest in your company,.
When Does a Control Premium NOT Apply?
Control premiums are not universally appropriate. Several valuation contexts either require or produce values on a minority basis without the need for a control premium:
Gift and estate tax: The IRS expects fair market value to reflect the hypothetical willing buyer/seller standard. For interests that do not carry control rights, fair market value reflects the minority, non-marketable basis. Applying a control premium to a gift or estate tax valuation of a minority interest would overstate value and increase gift or estate tax liability.
Minority shareholder oppression cases: Courts in some states require the fair value (not fair market value) standard for dissenting shareholder appraisal rights, which may or may not include a DLOC depending on the jurisdiction. Some state courts have held that applying a DLOC in this context unfairly penalizes minority shareholders who are being squeezed out.
Divorce: Marital dissolution standards vary by state. Some states use fair market value (with DLOC and DLOM); others use fair value (which may exclude those discounts). Applying the wrong standard in a divorce valuation can result in a materially incorrect result.
Frequently Asked Questions
What is a control premium in business valuation?
A control premium is the additional per-share value attributed to a controlling interest in a business above the value of a non-controlling (minority) interest. It reflects the economic advantages of control, including the ability to set compensation, direct strategy, approve transactions, and determine the timing of a sale. In US M&A transactions, historical control premiums have ranged from 20% to 40% above the minority market price, with variation by industry, deal size, and competitive dynamics.
What is the discount for lack of control (DLOC)?
The DLOC (discount for lack of control) is the inverse of the control premium. It is applied to convert a controlling interest enterprise value to a minority interest per-share value. For a 30% control premium, the DLOC is approximately 23%. The DLOC reflects the economic disadvantage of owning a minority position in a private company, where the holder cannot direct management, compel distributions, or force a sale.
Does a control premium always apply in M&A?
A control premium is almost always paid in acquisitions of publicly traded companies because the buyer is offering a premium above the observable minority market price to induce shareholders to tender their shares. In private company acquisitions, a control premium is implicit in the transaction price but is not always separately identified. When applying market multiples from public company guideline transactions (which reflect control prices) to a private company, the control premium is already embedded in the transaction multiple.
How does a control premium affect estate planning?
In estate planning, the controlling or minority nature of the interest being transferred determines whether a control premium or DLOC applies to the value. A controlling interest transferred to an heir is valued on a controlling basis, reflecting the full ability to direct the business. A minority interest transferred is valued on a minority, non-marketable basis, typically with both a DLOC and DLOM, reducing the taxable value.
Can two parties to a buy-sell agreement dispute the control premium?
Yes. Buy-sell agreement disputes frequently involve disagreements over whether the controlling or minority standard applies to the buyout price. Some buy-sell agreements specify the basis of value (controlling vs. minority; with or without discounts); others are silent, leaving the determination to the appraiser or to litigation. Sofer Advisors has served as expert witnesses in shareholder disputes involving control premium and DLOC disagreements, providing written reports and court testimony on the appropriate standard and magnitude of the discount.
How is a control premium determined for a private company?
For private companies, the control premium is derived from empirical data rather than observable market prices. Appraisers reference control premium studies from Mergerstat/BVR Control Premium Study and similar databases, which track the premiums paid in thousands of M&A transactions. The applicable premium is selected based on the subject company’s industry, size, growth characteristics, and the degree of competition expected from strategic buyers.
What is the difference between a control premium and a combined value premium?
A control premium reflects the general economic value of holding a controlling position, including all the prerogatives of control such as setting compensation, declaring distributions, and directing strategy. A combined value premium (also called a strategic premium) is an additional amount a specific buyer may pay above the control premium because the acquisition generates strategic combined benefits specific to that buyer, such as cost savings from eliminating redundant functions, or revenue combined benefits from combining complementary customer bases.
Does DLOC apply in divorce business valuations?
It depends on the state and the applicable standard of value. In states where divorce business valuations use fair market value (FMV), both DLOC and DLOM may be applicable for minority interests. In states where the standard is fair value (as defined by state law), courts may exclude minority and marketability discounts on the grounds that applying them unfairly penalizes the non-owner spouse.
How large is a typical DLOM for a private company minority interest?
DLOMs for private company minority interests typically range from 15% to 35%, with most well-supported valuations landing in the 20%-30% range. The magnitude depends on factors including company size (larger companies have smaller DLOMs), earnings history and stability, dividend history, the specific nature of the interest, any put or contractual liquidity rights, and the breadth of the restricted stock study or option pricing model evidence used to support the discount.
What databases do appraisers use to research control premiums?
Business appraisers research control premiums using databases that track actual M&A transaction prices relative to pre-announcement stock prices. The most widely referenced sources include the Mergerstat/BVR Control Premium Study (which covers thousands of US public company acquisitions), Capital IQ transaction data, and BVR transaction databases for private company deals. Sofer Advisors uses these databases in combination with DealStats and PitchBook to support control premium and DLOC conclusions in written appraisal reports that satisfy IRS, auditor, and court evidentiary standards.

Executive Summary
A control premium is the additional value attributable to a controlling interest above the minority interest value on a per-share basis, reflecting the economic advantages of directing management, operations, and exit timing. Historical US M&A data shows median control premiums of 20%-40%. The discount for lack of control (DLOC) is the inverse applied to minority interest valuations. Both are sequentially combined with the DLOM in private company minority interest valuations. Control premiums are not appropriate in all contexts; their application in estate, gift tax, divorce, and shareholder oppression cases depends on the applicable standard of value and jurisdiction. Sofer Advisors applies these adjustments with documented precision in every engagement.
