Description of Business	Description of Business We are a digital sports entertainment and gaming company. We provide users with online sports betting (“Sportsbook”), online casino (“iGaming”) and daily fantasy sports (“DFS”) product offerings, as well as retail sportsbook, media and other consumer product offerings. We are also involved in the design and development of sports betting and casino gaming software for online and retail sportsbooks and iGaming operators. In May 2018, the Supreme Court (the “Court”) struck down on constitutional grounds the Professional and Amateur Sports Protection Act of 1992, a law that prohibited most states from authorizing and regulating sports betting. As of March 31, 2024, 35 U.S. states, the District of Columbia and Puerto Rico have legalized some form of sports betting. Of those 37 legal jurisdictions, 32 have legalized online sports betting. All 32 of those jurisdictions are live, and DraftKings operates in 25 of them. The U.S. jurisdictions with statutes legalizing iGaming are Connecticut, Delaware, Michigan, New Jersey, Pennsylvania, Rhode Island and West Virginia. As of March 31, 2024, we operate our Sportsbook product offering in Arizona, Colorado, Connecticut, Illinois, Indiana, Iowa, Kansas, Kentucky, Louisiana, Maine, Maryland, Massachusetts, Michigan, New Hampshire, New Jersey, New York, North Carolina, Ohio, Oregon, Pennsylvania, Tennessee, Vermont, Virginia, West Virginia, Wyoming and Ontario, Canada, and we operate retail sportsbooks in Arizona, Colorado, Connecticut, Illinois, Iowa, Kansas, Kentucky, Louisiana, Michigan, Mississippi, New Hampshire, New Jersey and Washington. As of March 31, 2024, we operate our iGaming product offering in Connecticut, Michigan, New Jersey, Pennsylvania, West Virginia and Ontario, Canada. The Company also has arrangements in place with land-based casinos to expand operations into additional states upon the passing of relevant legislation, the issuance of related regulations and the receipt of required licenses. Pending Acquisition of JackPocket Inc. (“Jackpocket”) On February 11, 2024, the Company entered into a definitive agreement (the “Merger Agreement”) to acquire Jackpocket for total consideration of $750 million, with approximately 55 percent of the consideration payable in cash funded from the Company’s existing cash and cash equivalents balance, and approximately 45 percent of the consideration payable in the Company’s Class A common stock, subject to customary purchase price adjustments and the collar mechanism described below (the “Jackpocket Transaction”). Under the terms of the Merger Agreement and subject to the terms and conditions set forth therein, the stock consideration will be subject to a collar pursuant to which a variable number of shares of DraftKings’ Class A common stock will be issued to Jackpocket stockholders in order to deliver a value of $337.5 million, so long as the 30-trading-day volume weighted average price of DraftKings’ Class A common stock as of the second trading day immediately preceding the closing of the Jackpocket Transaction (the “Closing Stock Price”) remains between $31.68 and $42.86. In the event that DraftKings’ Closing Stock Price is above $42.86 or below $31.68, Jackpocket stockholders will receive a fixed number of approximately 7,874,806 shares and 10,654,149 shares, respectively, of DraftKings’ Class A common stock, subject to adjustment in certain limited circumstances to the minimum extent necessary to maintain a tax-free transaction. The consummation of the Jackpocket Transaction is subject to the receipt of required regulatory approvals and other customary closing conditions.
