Public Comps, short for Comparable Company Analysis, is a popular Valuation technique that determines a company's value by comparing it to similar, publicly traded companies. Think of it like real estate: to price a three-bedroom house, you'd look at the recent sale prices of other three-bedroom houses in the same neighborhood. In the same way, Public Comps assumes that similar companies in the same industry will have similar valuation multiples. This method provides a “relative valuation”—it tells you what your target company might be worth relative to its peers, based on current market sentiment. It’s a quick and powerful tool for getting a ballpark estimate of a company's value, but as with any tool, its effectiveness depends entirely on how skillfully it's used.
At its heart, Comparable Company Analysis is a four-step dance. It's less of a rigid science and more of an art form that requires good judgment. Let's break down the choreography.
This is the most critical step. A flawed Peer Group will lead to a nonsensical valuation. The goal is to find companies that are genuinely comparable to your target company. You're looking for businesses with similar DNA. Key characteristics to screen for include:
Once you have your peer group, it's time to play detective. You'll need to dig into their financial statements, which for public companies are readily available through regulatory websites like the U.S. SEC filings database (EDGAR). You'll be looking for key figures from their 10-K (annual) and 10-Q (quarterly) reports, such as revenue, EBITDA, net income, debt, and cash.
Now for the math. A valuation multiple is simply a financial ratio that compares a company's value to one of its financial metrics. This allows you to compare companies of different sizes on a level playing field. The most common multiples fall into two categories:
For each company in your peer group, you calculate these key multiples. Then, you typically calculate the mean (average) and median (middle value) multiple for the entire group. The median is often preferred as it's less skewed by extreme outliers.
This is the final step where you bring it all home. You take the average or median multiple from the peer group and apply it to your target company's own financial metric to estimate its value. For example: If the median EV/EBITDA multiple of the peer group is 8.0x, and your target company's EBITDA is $50 million, your calculation would be:
This gives you a valuation range for your target company. Voilà! You've just performed a basic Comparable Company Analysis.
While the steps seem straightforward, comps are a blend of objective data and subjective judgment.
For a value investor, Public Comps is a useful tool but never the final word. It's a great way to take the market's temperature and see how a company is perceived by other investors. However, it measures relative value, not absolute value. A value investor's primary goal is to determine a company's Intrinsic Value—what it's fundamentally worth based on its future cash-generating ability, independent of fleeting market sentiment. This is where a method like Discounted Cash Flow (DCF) analysis shines. Therefore, a savvy value investor uses comps as a starting point or a sanity check. If your DCF analysis says a company is worth $100 per share, but its peers are all trading at multiples that imply a value of $50 per share, it forces you to ask important questions. Why is there a discrepancy? Have you been too optimistic in your DCF assumptions, or have you discovered a genuinely undervalued gem that the market is overlooking? That's where the real work—and the real opportunity—begins.
