Oper ating Metr ics Dollar- Based Net Expansion Rate. Kaleyra’s ability to drive growth and generate incremental revenue depends, in part, on the Company’s ability to maintain and grow its relationships with Active Existing Customer Accounts and to increase their use of the platform. An important way in which Kaleyra has historically tracked performance in this area is by measuring the Dollar- Based Net Expansion Rate for those customer accounts. Kaleyra’s Dollar- Based Net Expansion Rate increases when such customer accounts increase their usage of a product, extend their usage of a product to new applications or adopt a new product. Kaleyra’s Dollar- B as ed Net Expansion Rate decreases when such customer accounts cease or reduce their usage of a product or when the Company lowers usage prices on a product. Kaleyra believes that measuring Dollar- Based Net Expansion Rate provides a more meaningful indication of the performance of the Company’s efforts to increase revenue from existing customers. To calculate the Dollar- Based Net Expansion Rate, the Company first identifies the cohort of customer accounts that were customer accounts in the same quarter of the prior year. The Dollar- Based Net Expansion Rate is the quotient obtained by dividing the revenue generated from that cohort in a quarter, by the revenue generated from that same cohort in the corresponding quarter in the prior year. Active Existing Customer Accounts. Kaleyra believes that the number of Active Customer Accounts is an important indicator of the growth of its business, the market acceptance of its platform and future revenue trends. Kaleyra defines an Active Customer Account at the end of any reporting period as an individual account, as identified by a unique account identifier, for which Kaleyra has recognized revenue in the period. 24 Copyright © Kaleyra, Inc. 2023
