Net Advertising Revenue Retention = (Revenue Recognized by Prior Year Advertisers in Current Year Period (excluding revenue from acquisitions during the stub period)) / (Revenue Recognized by Prior Year Advertisers in Prior Year Period (excluding revenue from acquisitions during the stub period)). Excludes advertisers that generated less than $10,000 of revenue in the measurement period; combined retention is the weighted average net advertising revenue retention of the company. As a result of the aggregation of certain reporting systems related to the integration of several acquisitions, retention data for Q1 2021 and Q2 2021 reflects certain estimates. 3.

Total gross quarterly subscription revenues divided by customers as defined in footnote (1); 4. “Churn Rate” = A / B. A = (average revenue per subscription in the prior month) x (number of cancels in current month), calculated at each business and aggregated. B = subscription revenue in the current month, calculated at each business and aggregated. Churn rate is presented on a quarterly basis. For Ookla, this is calculated by taking the sum of the monthly revenue from the specific cancelled agreements.
