| &nbsp;&nbsp;![GRAPHIC](mrdb-20230221xex99d1g031.jpg) | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;GLOSSARY OF TERMS 31 Term Definition Annual Recurring Revenue ("ARR") • We view Annual Recurring Revenue ("ARR") as an important indicator of our financial performance and operating results given the renewable nature of our business. ARR does not have a standardized meaning and is therefore unlikely to be comparable to similarly titled metrics presented by other companies. • We define ARR as the annualized revenue for our subscription customers, excluding revenue from nonrecurring contract services (e.g., time and material consulting services). For our annual subscription customers, we calculate ARR as the annualized value of their subscription contracts as of the measurement date, assuming any contract that expires during the next 12 months is renewed on its existing terms (including contracts for which we are negotiating a renewal). • In the event that we are negotiating a renewal with a customer after the expiration of their subscription, we continue to include that revenue in ARR if we are actively in discussion with the customer for a new subscription or renewal, or until we are notified that the customer will not be renewing its subscription. • Additionally, a subset of customers under the MariaDB SkySQL subscription service offering has monthly pay-as-you-go contract terms. We calculate ARR as their monthly recurring revenue as of the measurement date, multiplied by 12. We consider these annualized pay-as-you-go revenues relevant in the determination of ARR as it aligns with our strategic goal to convert the pay-as-you-go customers to annual subscription customers. • Our calculation of ARR is not adjusted for the impact of any known or projected events that may cause any such contract not to be renewed on its existing terms. Consequently, our ARR may fluctuate within each quarter and from quarter to quarter. This metric should be viewed independently of U.S. GAAP revenue and does not represent U.S. GAAP revenue on an annualized basis, as it is an operating metric that can be impacted by contract start and end dates and renewal rates. ARR is not intended to be a replacement for or forecast of revenue. Compounded Annual Growth Rate ("CAGR") • Average rate of growth over a period of time. Churn • Churn refers to a reduction of ARR that was present on day 1 of a fiscal period and DECREASES during the period.
