(“we,” “our,” “us,” or “the Company”) delivers one-to-one personalization to our clients through the combination of data science and human judgment. Our stylists hand select items from a broad range of merchandise. Stylists pair their own judgment with our analysis of client and merchandise data to provide a personalized shipment of apparel, shoes, and accessories suited to each client’s needs. We call each of these unique shipments a Fix. After receiving a Fix, our clients purchase the items they want to keep and return the other items. We are incorporated in Delaware and have operations in the United States and the UK.</span></div><div style="line-height:120%;padding-bottom:8px;text-align:justify;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;font-style:italic;font-weight:bold;">Initial Public Offering</span></div><div style="line-height:120%;padding-bottom:8px;text-align:justify;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">On November 16, 2017, we completed an initial public offering, or IPO. In connection with the IPO, we authorized </span><span style="font-family:inherit;font-size:10pt;"><span>two</span></span><span style="font-family:inherit;font-size:10pt;"> new classes of common stock: Class A common stock and Class B common stock. The rights of the holders of Class A and Class B common stock are identical, except with respect to voting, conversion and transfer rights. Each share of Class A common stock is entitled to </span><span style="font-family:inherit;font-size:10pt;"><span>one</span></span><span style="font-family:inherit;font-size:10pt;"> vote per share and each share of Class B common stock is entitled to </span><span style="font-family:inherit;font-size:10pt;"><span>ten</span></span><span style="font-family:inherit;font-size:10pt;"> votes per share. Each share of Class B common stock is convertible at any time at the option of the stockholder into </span><span style="font-family:inherit;font-size:10pt;"><span>one</span></span><span style="font-family:inherit;font-size:10pt;"> share of Class A common stock and has no expiration date. The Class B common stock automatically converts to Class A common stock upon transfers or any sale. In the IPO, we issued and sold </span><span style="font-family:inherit;font-size:10pt;"><span>8,000,000</span></span><span style="font-family:inherit;font-size:10pt;"> shares of our Class A common stock at a public offering price of </span><span style="font-family:inherit;font-size:10pt;"><span>$15.00</span></span><span style="font-family:inherit;font-size:10pt;"> per share. We received </span><span style="font-family:inherit;font-size:10pt;"><span>$110.4 million</span></span><span style="font-family:inherit;font-size:10pt;"> in net proceeds after deducting </span><span style="font-family:inherit;font-size:10pt;"><span>$6.2 million</span></span><span style="font-family:inherit;font-size:10pt;"> of underwriting discounts and </span><span style="font-family:inherit;font-size:10pt;"><span>$3.4 million</span></span><span style="font-family:inherit;font-size:10pt;"> in offering costs. Upon the closing of the IPO, all of the then-outstanding shares of common stock were reclassified into Class B common stock, all of the outstanding shares of convertible preferred stock automatically converted into </span><span style="font-family:inherit;font-size:10pt;"><span>59,511,055</span></span><span style="font-family:inherit;font-size:10pt;"> shares of Class B common stock, and all of the outstanding preferred stock warrants were automatically exercised into </span><span style="font-family:inherit;font-size:10pt;"><span>1,066,225</span></span><span style="font-family:inherit;font-size:10pt;"> shares of Class B common stock.
