Definition and Core Concept

Private company valuation refers to the process of determining the economic value of a privately held business. Unlike publicly traded firms, private companies do not have an open market for their shares, which means there is no readily available market price to reference. As a result, their valuation requires the application of structured methodologies, financial analysis, and assumptions to arrive at a defensible estimate of what the business is worth. Valuations are frequently conducted for a range of purposes, including mergers and acquisitions, tax compliance, fundraising, succession planning, litigation, and financial reporting.

Key Challenges

Valuing private companies involves more uncertainty and subjectivity than valuing public companies. Private firms are not required to disclose financial information publicly, so access to data can be limited. Their financial statements may follow different accounting standards or include discretionary expenses that distort the company’s real earnings capacity. Moreover, lack of market liquidity means the shares in private companies are often discounted due to their illiquidity and lack of transferability. Valuators must address these limitations while attempting to derive a reasonable and supportable value.

Common Valuation Approaches

Three primary approaches are used to value private companies: the income approach, the market approach, and the asset-based approach. Each method offers a different perspective and may be more appropriate depending on the industry, size, and maturity of the business.

Income Approach

The income approach calculates the present value of expected future cash flows or earnings. The two most common techniques under this approach are the discounted cash flow (DCF) method and the capitalization of earnings method. The DCF method projects future cash flows and discounts them to present value using a discount rate that reflects the company’s risk. The capitalization of earnings method is typically used for more stable businesses, using a single year’s earnings and a capitalization rate to estimate value.

This approach is often considered when reliable cash flow projections are available, especially in growth-stage companies where market comparables may not exist or be reliable.

Market Approach

The market approach bases valuation on comparisons with similar businesses. This method looks at transaction multiples (such as price-to-earnings or enterprise value-to-EBITDA) from comparable public companies or private business sales. Adjustments are made to account for differences in size, risk, growth potential, and capital structure.

The challenge with this approach is identifying truly comparable companies, especially for niche or early-stage businesses. Public comparables also trade with a liquidity premium that may not apply to private firms, requiring a discount for lack of marketability.

Asset-Based Approach

This method involves estimating the net value of a company’s assets minus its liabilities. It is most commonly used for asset-intensive businesses or companies facing liquidation. The adjusted net asset method revalues the company’s assets and liabilities to reflect their fair market values rather than book values.

For operating businesses, this method is typically a lower bound of value, as it may not fully capture the income-generating potential of intangible assets like brand, intellectual property, or customer relationships.

Adjustments and Discounts

Because private companies do not benefit from the liquidity and transparency of public markets, valuation professionals often apply specific discounts and adjustments. Two of the most widely used are:

• Discount for Lack of Marketability (DLOM): Reflects the reduced ability to quickly sell shares of a private company due to the absence of a secondary market.
• Discount for Lack of Control (DLOC): Applied when valuing a minority interest, recognizing that such ownership typically comes with limited decision-making power.

These discounts are highly judgment-based and vary depending on factors like company size, revenue stability, and governance structure.

Purpose-Specific Considerations

Valuation outcomes may differ based on the context and purpose of the valuation. For example, the Internal Revenue Service (IRS) requires specific standards for valuations used in estate and gift tax planning. In contrast, venture capital investors may base valuations on negotiation, market sentiment, and expected returns rather than purely on financial fundamentals.

Similarly, in shareholder disputes or divorce proceedings, courts may require valuations to follow state-specific rules, including fair value or fair market value standards. Valuations prepared for financial reporting must follow guidelines such as ASC 820 or IFRS 13, depending on jurisdiction.

Professional Standards and Regulation

Private company valuations are often conducted by credentialed professionals, such as those holding the Chartered Business Valuator (CBV), Accredited Senior Appraiser (ASA), or Certified Valuation Analyst (CVA) designations. While private valuations are less regulated than public company disclosures, adherence to professional valuation standards, such as those set by the AICPA or the International Valuation Standards Council (IVSC), helps ensure consistency and credibility.

The Bottom Line

Private company valuation is a complex process requiring financial analysis, industry knowledge, and professional judgment. With no observable market price, private valuations rely on models that incorporate projections, assumptions, and comparable data to derive an estimate of value. Whether for internal planning, legal matters, or transactions, a reliable valuation can be a critical tool for business owners, investors, and advisors.
