388  Using Multiples Spotify offers music streaming on demand. Sirius XM combines on-demand and radio-format music streaming (via its 2019 Pandora acquisition) with its original business of satellite radio broadcasting. All three generate revenues from user subscriptions, but Spotify and Sirius XM also generate advertising income. For Netflix, the cost of streamed content is largely independent of the number of users; it produces an increasing portion of the content itself and does not pay per view to its content suppliers. Spotify, in contrast, does not produce content and pays an amount per song-play to the content own- ers (record companies and artists). Sirius XM develops part of its content (for example, its radio shows) and buys music from third parties—also paying per song-play, but at lower rates for radio broadcasting than for on-demand streaming. In addition, the companies’ user growth rates for 2019 varied widely: about 30 percent for Spotify, 20 percent for Netflix, and 3 percent for Sirius XM (with Sirius active in the United States only and Netflix and Spo- tify in many countries). Because of these differences in user economics and growth, an average of the value per user of Netflix, Spotify, and Sirius XM is not very meaningful for valuing another online music or video-streaming business. You would need to analyze the underlying business model in detail to understand which of the three is the most comparable business. In the end, what matters is the underlying value creation, not the number of users, website hits, or unique visitors. In the late-1990s Internet examples from Fortune, Yahoo traded at a higher multiple than Amazon.com because in- vestors expected that Yahoo’s profit per user would be higher than Amazon’s. Academic studies have demonstrated for these valuations that the number of unique visitors to a website or the number of pages on a site viewed per visit was directly correlated to a company’s stock price, even after controlling for the company’s current financial performance.13 The power of a given nonfi- nancial metric, however, depended on the company. For portal and content companies such as Yahoo, page views and unique visitors were both corre- lated to a company’s market value. For online retailers such as Amazon.com, only the page views per visit were correlated with value. Evidently, the mar- ket believed that merely stopping by would not translate to future cash flow for online retailers. Research has also shown that as an industry matures, financial metrics such as gross profit and R&D spending become increasingly predictive, whereas nonfinancial data tend to lose power.14 This indicates a return to traditional valuation metrics for new industries as they mature and once financial metrics became meaningful. 13 B.

Summary  389 A problem with all multiples is that they are relative valuation tools. They measure one company’s valuation relative to another’s, normalized by some measure of size, be it size of earnings, revenues, or number of customers. They do not measure absolute valuation levels. For multiples based on operating metrics, there is an additional challenge of interpretation, because you can only compare them across a very limited number of companies that have a very similar operating model. Financial multiples are easier to interpret and compare. Take the example of an EV-to-EBITA multiple of 20 times for a ma- ture industrial company. Basic understanding of underlying value drivers can readily lead you to a first conclusion: this multiple reflects high expectations for ROIC and growth (at a reasonable cost of capital). But it is much harder to come to such a conclusion when you observe an EV multiple of $1,200 per customer. Summary Of the available valuation tools, discounted cash flow continues to deliver the best results. However, a thoughtful comparison of selected multiples for the company you are valuing with multiples from a carefully selected group of peers merits a place in your tool kit as well. When that comparative analysis is careful and well reasoned, it not only serves as a useful check of your DCF forecasts, but also provides critical insights into what drives value in a given industry. The distinction between operating and nonoperating results, capital, and cash flows should follow the exact same logic as applied in DCF valua- tion. The most insightful multiples are those that compare operating value to operating results. Operating metrics such as mineral reserve size or number of subscribers can be used when these are clearly related to value creation. In all cases, be sure that you analyze the underlying reasons that multiples differ from company to company, and never view multiples as a shortcut to valuation. Instead, approach your multiples analysis with as much care as you bring to your DCF analysis.
