Organization, Consolidation and Presentation of Financial Statements [Abstract]
NATURE OF OPERATIONS	NATURE OF OPERATIONS Cardlytics, Inc. ("we," "our," "us," the "Company," or "Cardlytics") is a Delaware corporation and was formed on June 26, 2008. We operate a commerce media platform that is designed to make commerce smarter and rewarding for everyone. At the core of our commerce media platform is the financial media network that we run within our partners' digital channels, which includes online and mobile applications (the "Cardlytics platform"). Additionally, we operate an identity resolution platform that utilizes point-of-sale ("POS") data, including product-level purchase data, to enable marketers to perform analytics and targeted loyalty marketing and also measure the impact of their marketing (the "Bridg platform"). The partners for the Cardlytics platform are predominantly financial institutions ("FI partners") that provide us with access to their anonymized purchase data and digital banking customers. The partners for the Bridg platform are predominantly merchants ("merchant data partners") that provide us with access to their POS data, including product-level purchase data. By applying advanced analytics to the purchase data we receive, we make it actionable, helping marketers reach potential buyers at scale and measure the true sales impact of their marketing spend. We have strong relationships with leading marketers across a variety of industries, including everyday spend, specialty retail, restaurant, travel and entertainment. Using our transaction data and analytics, we enable marketers to reach potential customers across our network of FI partners through their digital banking accounts and present them relevant offers to save money when they are thinking about their finances. We also operate through (1) Dosh Holdings LLC, a wholly owned and operated subsidiary in the United States and (2) Cardlytics UK Limited, a wholly owned and operated subsidiary registered as a private limited company in England and Wales. 2024 Convertible Senior Notes On April 1, 2024, we issued $172.5 million principal amount of our 4.25% Convertible Senior Notes due in 2029 (the "2024 Convertible Senior Notes") in a private offering, including the exercise in full of the initial purchasers' option to purchase up to an additional $22.5 million principal amount of the 2024 Convertible Senior Notes. Refer to Note 9—Debt and Financing Arrangements for further details. Equity Distribution Agreement On January 29, 2024, we filed a shelf registration statement on Form S-3 with the Securities and Exchange Commission ("SEC"), which was declared effective by the SEC on February 9, 2024. This shelf registration statement, which includes a base prospectus, allows us to offer and sell up to a maximum aggregate offering amount of $100.0 million of our registered common stock, preferred stock, debt securities, warrants, or any combination of securities described in the prospectus in one or more offerings. On March 18, 2024, we entered into an equity distribution agreement (the "Equity Distribution Agreement") with Evercore Group L.L.C., BofA Securities, Inc. and Cantor Fitzgerald & Co., as sales agents, pursuant to which we may issue and sell, from time to time, shares of our common stock up to a maximum aggregate offering amount of $50.0 million in "at-the-market" offerings (the "ATM Offering Program"). On March 18, 2024, we sold 3,907,600 shares of our common stock at a weighted average price per share of $12.80, for aggregate net proceeds of $48.3 million after deducting commissions and estimated offering expenses payable by us, pursuant to the Equity Distribution Agreement and completed the ATM Offering Program. Divestitures and Acquisitions The Dosh app, a consumer facing cashback mobile application operated by Dosh Holdings LLC, was decommissioned on February 28, 2025. On December 7, 2023, we sold and transferred substantially all of the assets of Entertainment for $6.0 million in cash, subject to a combined $1.1 million held in escrow for indemnities and sales and use taxes, as well as customary post-closing adjustments. The resulting loss on sale of $6.6 million is recorded within "Loss on divestiture" within the statement of operations. During the year-ended December 31, 2024, we received $0.6 million of cash from escrow, and we classified the receipt of cash within investing activities within the consolidated statement of cash flows. We also recorded a $0.1 million divestiture expense associated with the net working capital adjustment. Contingent Consideration for the Acquisition of Bridg As part of our acquisition of Bridg and pursuant to the terms of the Agreement and Plan of Merger dated as of April 12, 2021, as amended (the "Merger Agreement"), we agreed to make two earnout payments: the First Anniversary Payment Amount and the Second Anniversary Payment Amount, based on the First Anniversary ARR and the Second Anniversary ARR of Bridg, respectively. As of December 31, 2023, we had paid the First Anniversary Payment consisting of $50.1 million of cash and 2,740,418 shares of our common stock to the Stockholder Representative, inclusive of brokerage fees and transaction bonuses and accounting for all true-ups and credits. On January 25, 2024, we entered into a settlement agreement (the "Settlement Agreement") with the Stockholder Representative to resolve all outstanding disputes related to the Merger Agreement, pursuant to which we agreed to pay $25.0 million in cash and issue 3,600,000 shares of our common stock to the Stockholder Representative, inclusive of broker fees and transaction bonuses. Pursuant to the Settlement Agreement we paid the Stockholder Representative $20.0 million in cash on January 26, 2024 and we issued 3.6 million shares of our common stock on February 1, 2024. We subsequently paid the Stockholder Representative $3.0 million in cash on January 29, 2025. The remaining $2.0 million cash payment related to the Settlement Agreement will be paid by June 30, 2025.
