We define ARPU as our total revenue in a given geography during a period divided by average MAUs in that geography during the period. We calculate average MAUs based on the average of the number of MAUS measured on the last day of the current period and the last day prior to the beginning of the current period. We calculate ARPU by geography based on our estimate of the geography in which revenue-generating activities occur. $5.92 Q223 $0.12 Q223 (1%) Global Y/Y +2% US & Canada Y/Y +6% Europe Y/Y +20% Rest of World Y/Y 9
