Calculating the value of shares in a private company is a critical process impacting multiple business decisions, from exit planning and shareholder buyouts to mergers and acquisitions (M&A), estate planning, and tax efficiency. Unlike public companies with market-driven prices, private companies rely on financial models and market comparisons. This article looks at the differences between valuing public and private shares, discusses the challenges, and outlines essential valuation methods. Understanding how to calculate the value of shares in a private company guarantees fair transactions and sound financial planning.

Why Private Company Valuation Matters
Knowing the worth of your ownership stake is about your future and your business’s health. Here’s why private company valuation is essential:
- Exit Planning: Understanding your share value allows you to strategically plan your exit, ensuring a smooth and financially sound departure. A solid valuation sets the stage for understanding the financial outcome of your years of hard work. If you’re considering selling, a valuation helps you negotiate a better deal. Knowing how to calculate the value of shares in a private company is crucial for a successful exit strategy.
- Shareholder Buyouts: Accurate valuation ensures fair buyout prices for both minority and majority shareholders, maintaining equity and harmony. When partners part ways or new investors arrive, a fair valuation makes sure everyone receives a square deal.
- Mergers & Acquisitions (M&A): Valuation is critical for negotiating M&A deals, ensuring you’re neither overpaying nor underselling. Thinking of expanding through acquisitions or being acquired? Accurate valuation is the cornerstone of successful negotiations, preventing you from leaving money on the table.
- Estate Planning: Proper valuation facilitates efficient asset distribution and minimizes potential inheritance tax burdens for your heirs, ensuring a seamless transfer of ownership. In estate planning, accurate valuation ensures that your heirs receive a fair share without incurring unnecessary tax burdens.
- Tax Efficiency: A well-supported valuation optimizes tax planning, minimizes liabilities, and helps you avoid IRS scrutiny. The IRS pays close attention to how private companies are valued. A well-supported valuation optimizes your tax liabilities and ensures compliance. For high-net-worth individuals, proper valuation is essential for optimizing tax planning, minimizing estate taxes, and ensuring compliance.

Understanding Private Company Valuation
Valuing a private company’s shares is more complex than valuing those of a public company. Public shares trade on stock exchanges, providing transparent market prices. Private shares, lacking this transparency, depend on financial models and comparisons.
Key Differences: Public vs. Private Shares
- Public Companies:
- Market-determined pricing through stock exchanges.
- Required financial disclosures providing transparency.
- Daily liquidity for shareholders.
- Standardized valuation metrics like P/E ratios.
- Private Companies:
- No established marketplace for shares.
- Limited financial disclosure requirements.
- Restricted liquidity for shareholders.
- More complex valuation considerations: We need financial models, market comparisons, and expertise to determine their value, as they don’t trade publicly.
What Affects Private Share Value?
Several factors influence the value of private company shares:
- Financial Performance: Revenue growth, profit margins, and cash flow stability directly impact valuation. Consistent, growing profits command higher valuations.
- Industry Dynamics: Market conditions, growth potential, and competitive positioning substantially affect value. Growing industries are more valuable. For example, companies in the oil and gas sector may be valued differently than those in real estate. Patten & Company has experience in oil & gas, agriculture/farming, real estate, and private equity and investment partnerships. Understanding these dynamics is crucial for valuation of private company shares.
- Company-Specific Factors: Management strength, proprietary technology, customer concentration, and reputation all play important roles. A strong brand, positive customer reviews, and a solid track record boost value.
- Control Considerations: Majority ownership positions command premium valuations due to decision-making authority. A control premium reflects the added value of being able to make key decisions.
- Marketability: Private shares lack the liquidity of public stocks, often resulting in valuation discounts. Private company valuations may include discounts like the Lack of Marketability Discount (DLOM), acknowledging that private shares are less liquid than public shares. The absence of a liquid market impacts private company stock valuation significantly.
Why Valuation is Essential for CEO Succession & Estate Planning
In privately held companies, ownership is often the most significant asset. When a CEO steps down or it’s time for estate planning, a business valuation provides clarity, ensuring a fair transition of leadership and ownership. Without accurate share valuation, leadership transitions can become contentious and potentially damaging to the business. Want to learn more about ensuring a smooth leadership transition?

Key Valuation Methods For Private Company Shares
When professionals value a business, they usually use more than one way to get an accurate price range. Each approach offers unique insights and suits different industries and company types.
Discounted Cash Flow (DCF) Method
The Discounted Cash Flow (DCF) method values a company based on the present value of its projected future cash flows. It estimates the cash a company is expected to generate and then discounts it back to its present value using a risk-adjusted discount rate. DCF is particularly suitable for companies with a history of stable revenue and predictable cash flows, such as those in the oil and gas sector. This approach is fundamental to company share valuations.
- How DCF Works
- Project future cash flows for a specific period (typically 5-10 years).
- Calculate a terminal value representing cash flows beyond the projection period.
- Determine an appropriate discount rate that reflects the risk associated with the company’s cash flows and the time value of money (opportunity cost).
- Apply the discount rate to discount future cash flows to their present value.
- Sum the present values to arrive at the company’s valuation.
- Understanding the Discount Rate
- The discount rate is crucial in DCF as it reflects the opportunity cost of money.
- Opportunity Cost: Money in hand today is worth more than the promise of the same amount in the future because you could invest it today and potentially earn a return. The discount rate represents this potential return you’re giving up by waiting for future cash flows.
- Discounting vs. Compounding: Discounting is the reverse of compounding. Compounding is how your savings grow over time by earning interest on interest. Discounting determines how much a future amount is worth today, considering that it could have grown in the meantime.
- How to Apply DCF
- Estimate Future Cash Flows: Use historical data and industry trends to forecast future cash flows.
- Determine the Discount Rate: This should reflect the risk associated with the company’s cash flows and the time value of money.
- Example
With DCF, you can project future production, oil and gas prices, and operating expenses to estimate future cash flows, which helps in long-term valuation and investment decisions.
- DCF Advantages and Limitations:
- Advantages:
- Accounts for future growth potential.
- Considers timing of cash flows.
- Based on company-specific projections.
- Advantages:
- Limitations:
- Highly sensitive to assumptions about growth rates and discount rates.
- Challenging for companies with unpredictable cash flows.
- Requires detailed long-term financial forecasts.

Comparable Company Analysis (CCA)
Comparable Company Analysis (CCA) is a market-based approach to calculate value of shares in a private company by comparing it to similar public companies or recently sold private businesses. It involves benchmarking your company against similar companies in the same industry, using financial multiples like Price-to-Earnings (P/E), Enterprise Value to Earnings Before Interest, Taxes, Depreciation, and Amortization (EV/EBITDA), and Revenue Multiples.
- How CCA Works
- Identify similar companies based on industry, size, and business model.
- Calculate key valuation multiples for comparable companies (e.g., EV/EBITDA, P/E ratio).
- Adjust appropriately for differences in size, growth, and risk.
- Apply the adjusted multiples to your company’s financials.
We identify key financial multiples from comparable companies, such as Price-to-Earnings (P/E) ratios, EV/EBITDA multiples, and revenue multiples, and then apply them to your company.
- How to Apply CCA
- Identify Comparable Companies: Choose companies similar in size, industry, and growth stage.
- Calculate Financial Multiples: Use metrics like P/E and EV/EBITDA to compare with your company.
- Adjust for Differences: Consider factors like management quality and market position.
- Real-World Case
Let’s say you own a real estate firm. CCA would involve comparing your firm’s financial ratios to those of other similar real estate companies to arrive at a relative valuation.
- Common Valuation Multiples
- Enterprise Value (EV) Multiples:
- EV/EBITDA: Most widely used, especially for capital-intensive businesses – (Enterprise Value divided by Earnings Before Interest, Taxes, Depreciation and Amortization)
- EV/Revenue: Useful for high-growth companies not yet profitable – (Enterprise Value divided by Revenue)
- EV/EBIT: Accounts for depreciation differences between companies – (Enterprise Value divided by Earnings Before Interest and Taxes)
- Enterprise Value (EV) Multiples:
- Equity Multiples:
- Price-to-Earnings (P/E): Common but affected by capital structure differences – (Share price divided by earnings per share)
- Price-to-Book (P/B): Useful for asset-heavy businesses – (Share price divided by book value per share)
- Price-to-Sales (P/S): Applicable when comparing companies with similar margins – (Share price divided by sales per share)
- CCA Advantages and Limitations
- Advantages:
- Based on actual market valuations.
- Relatively simple to apply.
- Reflects current industry conditions.
- Advantages:
- Limitations:
- Difficult to find truly comparable companies.
- May not account for company-specific strengths or weaknesses.
- Requires adjustments for size, growth rates, and other factors.
Precedent Transactions Method
The Precedent Transactions Method gauges current value by looking at past deals, analyzing past M&A activity in the same industry. This method is useful for understanding valuation of private company shares.
- How it Works: We look at how similar companies were valued in previous mergers and acquisitions. We then adjust for any differences, such as deal specifics like earn-outs or control premiums.
- Example: Private equity firms often use this method when valuing potential acquisition targets. By examining what other firms paid for similar companies, they can arrive at a reasonable valuation.
Asset-Based Valuation
Asset-Based Valuation focuses on a company’s tangible assets, like a balance sheet approach. It’s essential in company share valuations.
- How it Works: We calculate the total value of a company’s assets (like land, equipment, and inventory) and then subtract its liabilities.
- Best For: Companies in sectors with significant tangible assets, such as real estate, agriculture, and some areas of oil & gas.
- Example: Valuing a Texas farmland business would heavily rely on this method. The value of the land, farm equipment, and any crops would be key factors.
First Chicago Method
In private equity and venture capital, the First Chicago Method is often used because it is complex.
- How it Works: This method involves creating multiple valuation scenarios—Best Case, Base Case, and Worst Case—and then weighting them based on their probabilities.
- Example: A startup seeking funding might use this method to present a range of potential outcomes to investors. It helps investors understand the potential upside and downside risks.
How Private Share Valuation Impacts Business Decisions
So, you’ve got a valuation. Now what? It directly influences key business decisions.
Shareholder Buyouts & Succession Planning
- Determining Fair Buyout Prices: A business valuation provides a foundation for determining fair prices in shareholder buyouts (minority or majority), crucial for maintaining harmony and equity.
- Ensuring a Smooth Leadership Transition: Business valuation plays a vital role in succession planning, helping transfer ownership smoothly and correctly account for the value accrued over the years. Understanding how to calculate value of shares in a private company is paramount for effective succession planning.
Tax & Legal Considerations in Valuation
- IRS Scrutiny: The IRS closely monitors private company valuations, especially for tax purposes. An accurate, well-documented valuation can help you avoid issues.
- Valuation Discounts: Private company valuations may include discounts like the Lack of Marketability Discount (DLOM), acknowledging that private shares are less liquid.
- High-Net-Worth Individuals: Proper valuation is essential for optimizing tax planning, minimizing estate taxes, and ensuring compliance. Seeking professional guidance on how to calculate value of shares in a private company can help HNW individuals navigate these complex considerations.
Common Valuation Mistakes & How To Avoid Them
Valuation can be tricky. Watch out for these common pitfalls:
- Overestimating Growth Projections: Overestimating future growth can lead to inflated valuations. Be realistic and data-driven.
To avoid this, conduct a thorough analysis of industry trends and historical performance when calculating the value of shares in a private company. - Ignoring Industry-Specific Risks: Failing to account for industry-specific risks results in inaccurate valuations. For example, valuing an oil and gas business involves very different risks than valuing a farming business. Understanding these nuances is critical when considering company share valuations.
