714  High-Growth Companies Sizing the Market  For many young, high-growth companies, it’s challeng- ing to estimate the size of the potential market. You must be creative and clever about what data to collect to bound your forecasts. In the case of the ride-share market, for example, you can start with global taxi revenue. But you must also consider how many new rides will occur because of the ease of access, as well as how many riders are likely to replace their cars altogether. Compared with other nascent technology companies, Farfetch’s product markets are easier to size. Many investment banks and consulting firms study the global luxury market in depth. Information is available on the number of products and the total value of merchandise sold in stores and online. Exhibit 36.4 presents revenue for the global luxury market between 2010 and 2018, with analyst forecasts extending through 2025. Bolstered by strong growth in Asia, the luxury market is expected to grow between 4 and 5 per- cent annually, reaching $450 billion by 2025. Growth looks to be uneven across channels, however. Expectations are that over the next decade, in-store sales of luxury products will remain flat, while online sales will increase from 10 percent to 25 percent of the total market. The online migration of luxury goods is far from certain, however. No one really knows if these high-end products will migrate as much or as quickly as have media, electronics, and other items. Later in the chapter we develop multiple scenarios, with each scenario based on a different level of online penetration.

A Valuation Process for High-Growth Companies  715 Modeling Revenues  A robust revenue model, especially for nascent compa- nies, will incorporate operational data mirroring the company’s economics. In the case of consumer companies, these include the number of custom- ers, transactions per customer, average transaction size, and other items. Exhibit 36.5 presents a revenue model for Farfetch’s third-party marketplace, based on forecasts by the research team at Cowen and Company.4 These par- ticular estimates underpin one of our four scenarios presented later in the chapter. The revenue model in Exhibit 36.5 starts with the number of customers, which in 2018 was approximately 1.4 million. Since the typical customer makes a purchase just over twice a year, the company generated just under 3 million transactions that year. The size of the average order was about $600, leading to an estimated $1.8 billion in gross transaction value. Since some transactions will EXHIBIT 36.5  Farfetch: Revenue Model for Third-Party Marketplace, 2017–2028E $ million, except where noted 2017 2018 2019E 2020E 2021E 2022E … 2028E Third-party revenue model Unique customers, thousands 936 1,353 1,787 2,293 2,897 3,603 … 9,911 × Orders per customer 2.01 2.15 2.31 2.33 2.35 2.38 … 2.52 Number of orders, thousands 1,881 2,913 4,121 5,342 6,817 8,563 … 25,005 × Average order value, $ 620 618 605 637 650 659 … 700 Gross transaction value1 1,166 1,801 2,493 3,402 4,428 5,645 … 17,500 Net of returns (290) (439) (577) (782) (1,018) (1,411) … (4,375) Net of fulfillment revenue (74) (98) (138) (197) (256) (318) … (984) GMV, net of fulfillment revenue2 802 1,265 1,777 2,423 3,154 3,917 … 12,140 × Portion generated by third party 95.0% 91.9% 91.5% 92.2% 92.8% 93.3% … 93.3% × Take rate 32.8% 32.5% 30.9% 30.9% 30.6% 30.3% … 29.4% Third-party revenue 250 377 503 691 896 1,108 … 3,331 Other Revenue Platform fulfillment revenue 74 98 138 197 256 318 … 984 First-party revenue 40 102 152 189 228 261 … 815 Black & White segment 6 10 16 23 30 37 135 Browns’ in-store revenue 15 16 18 20 22 23 … 30 Farfetch revenue 386 602 827 1,119 1,430 1,746 … 5,296 1 Excluding Black & White’s outsourcing revenue and Browns’ in-store revenue. 2 Gross merchandise value, net of fulfillment revenue.
