Definitions Adjusted contribution: We define adjusted contribution measures of the degree by which revenue generated from our marketers exceeds the cost to obtain the purchase data and the digital advertising space from our partners. Adjusted contribution demonstrates how incremental marketing spend on our platform generates incremental amounts to support our sales and marketing, research and development, general and administration and other investments. Adjusted contribution is calculated by taking our total revenue less our Partner Share and other third-party costs exclusive of deferred implementation costs, which is a non-cash cost. Adjusted contribution does not take into account all costs associated with generating revenue from advertising campaigns, including sales and marketing expenses, research and development expenses, general and administrative expenses and other expenses, which we do not take into consideration when making decisions on how to manage our advertising campaigns. Adjusted EBITDA: We define adjusted EBITDA as our (loss) income before income taxes; interest expense, net; depreciation and amortization expense; stock-based compensation expense; foreign currency gain (loss); deferred implementation costs; restructuring costs; acquisition and integration costs (benefit); and change in fair value of contingent considerations. Bridg ARR: We define ARR as the annualized GAAP revenue of the final month in the period presented for the Bridg platform. ARR should not be considered in isolation from, or as an alternative to, revenue prepared in accordance with GAAP. We believe that ARR is an indicator of the Bridg platform’s ability to generate future revenue from existing clients. Cardlytics ARPU: We define ARPU as the total Cardlytics platform revenue generated in the applicable period calculated in accordance with GAAP, divided by the average number of MAUs in the applicable period. Billings: Billings represents the gross amount billed to customers and marketers for advertising campaigns in order to generate revenue. Cardlytics platform billings is recognized gross of both Consumer Incentives and Partner Share. Cardlytics platform GAAP revenue is recognized net of Consumer Incentives and gross of Partner Share. Bridg platform billings is the same as Bridg platform GAAP revenue. Campaign spend ratio: We define campaign spend ratio as the amount of spend from MAUs that is associated with the campaigns in which they were targeted with offers divided by the total amount of spend from MAUs in the industries in which MAUs were targeted with offers during the applicable period. Cardlytics MAUs: We define MAUs as targetable customers or accounts that have logged in and visited online or mobile applications containing offers, opened an email containing an offer, or redeemed an offer from the Cardlytics platform during a monthly period. We then calculate a monthly average of these MAUs for the periods presented. Monthly log-in days: We define monthly log-in days as the number of days in which MAUs logged in and visited the online or mobile banking applications of, or opened an email containing our offers from, our partners during a monthly period. We then calculate an average of the monthly log-in days for the periods presented. Non-GAAP net loss: We define non-GAAP net loss as our net loss before stock-based compensation expense; foreign currency (gain) loss; acquisition and integration (benefit) costs; amortization of acquired intangibles; change in fair value of contingent considerations; and restructuring costs. Notably, any impacts related to minimum Partner Share commitments in connection with agreements with certain Partners are not added back to net loss in order to calculate adjusted EBITDA. Non-GAAP net loss per share: We define non-GAAP net loss per share as non-GAAP net loss divided by GAAP weighted-average common shares outstanding, diluted. Offer activation rate: We define offer activation rate as the total number of offers activated by MAUs divided by the total number of offers served to MAUs in the applicable period.
