The Company has more than a million small cell networks for cellular distributed antenna system ("DAS") and Wi-Fi access that reach more than one billion consumers annually. Boingo Wireless, Inc. was incorporated in April 16, 2001 in the State of Delaware. We have a diverse monetization model that enables us to generate revenues from retail sales, wholesale partnerships, and advertising across these small cell networks. Retail products include Wi-Fi subscriptions and day passes that provide access to more than 800,000 commercial hotspots worldwide, and Internet Protocol television ("IPTV") services and residential broadband for military barracks. Wholesale offerings include Wi-Fi roaming, private label Wi-Fi, location based services, and DAS, which are cellular extension networks. Advertising revenue is driven by Wi-Fi sponsorships at airports, hotels, cafes and restaurants, and public spaces. Our customers include some of the world's largest carriers, telecommunications service providers and global consumer brands, as well as Internet savvy consumers on the go and troops stationed at military bases. Initial public offering On May 3, 2011, our registration statement registering 3,846,800 shares of common stock offered by us and 1,923,200 shares offered by certain selling stockholders was declared effective by the United States Securities and Exchange Commission, and the shares began trading on the NASDAQ Global Market on May 4, 2011 under the symbol "WIFI." The proceeds from the sale of these shares are used primarily for working capital and other general corporate purposes. As a result of the initial public offering ("IPO"), we raised a total of approximately $45,701 in net proceeds after deducting underwriting discounts and commissions of approximately $3,635 and offering expenses of approximately $2,596. In connection with the IPO, all of the shares of our convertible preferred stock were converted into 22,845,764 shares of common stock and all of the warrants to purchase preferred stock were exercised and converted into 20,172 shares of common stock through net-share settlement. Reverse stock split On April 7, 2011, our board of directors approved a 5 for 1 reverse stock split of our outstanding common stock which was effected on May 3, 2011. Fractional shares were settled in cash totaling approximately $1 for common and preferred stockholders. No fractional shares were settled for option holders, and they were rounded down as a result of the reverse stock split. Shares of common stock underlying outstanding stock options and warrants and shares of our preferred stock and warrants were proportionately reduced and the respective exercise prices were proportionately increased in accordance with the terms of the agreements governing such securities. Shares of common stock reserved for issuance upon the conversion of our convertible preferred stock were proportionately reduced and the respective conversion prices were proportionately increased. All references to shares in the accompanying consolidated financial statements and the notes thereto, including but not limited to the number of shares and per share amounts, unless otherwise noted, have been adjusted to reflect the reverse stock split retroactively. Previously awarded options and warrants to purchase shares of our common and preferred stock have also been retroactively adjusted to reflect the reverse stock split.
