Some factors that could cause actual results to differ include: (a) our ability to continue as a going concern and to secure additional financing needed to meet short-term and long-term liquidity needs; (b) our ability to compete in an increasingly competitive environment (including in the relational database market, which may not continue to grow as expected); (c) our ability to retain and recruit qualified personnel, including officers (including a chief financial officer), directors and other key personnel (including those with public company experience); (d) our ability to expand, acquire and integrate technologies, personnel, and other assets (including those related to the acquisition of CubeWerx and Sector 42 by Legacy MariaDB and the cloud-related business); (e) our ability to retain existing customers and their business and attract additional customers and business; (f) intellectual property, information technology and privacy requirements that may subject us to unanticipated liabilities; (g) our ability to realize the anticipated benefits of the Business Combination, which may be affected by, among other things, competition, and our ability to manage our operations, including potential growth and expansion of our business operations (including in the cloud) and buildings out controls, effectively; (h) any regulatory actions or litigation relating to the Business Combination; (i) our ability to maintain the listing of our Ordinary Shares, Public Warrants or other securities on the NYSE; (j) the effects of the ongoing coronavirus (COVID-19) pandemic or other infectious diseases, health epidemics, pandemics, and natural disasters on our business; and (k) other risks and uncertainties indicated from time to time in our SEC filings, such as on Forms 10-Q and 10-K, including those under "Risk Factors" therein, and other documents filed or to be filed with the SEC by us, which you should review and consider.

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. Average rate of growth over a period of time. Churn refers to a reduction of ARR that was present on day 1 of a fiscal period and DECREASES during the period. The company's open source software is code that is designed to be publicly accessible-anyone can see, modify, and distribute the code as they see fit. Millions; generally referring to dollars or shares. Total Cost of Ownership, typically calculated over a timeframe, inclusive of license and support or a subscription including support. Structured Query Language, computer language to store, manipulate or access data in a relational database. MariaDB 31
