Who We Are Property of Rimini Street©2023 \| Proprietary and Confidential 4 OPTIMIZE \| EVOLVE \| TRANSFORM Rimini Street (Nasdaq: RMNI) is a global provider of end-to-end enterprise software support, products and services. The Company offers a comprehensive family of unified solutions to run, manage, support, customize, configure, connect, protect, monitor, and optimize clients' enterprise application, database, and technology software platforms. We founded Rimini Street to disrupt and redefine the enterprise software support market by developing and delivering innovative new solutions that filled a then-unmet need in the enterprise software market. We became and remain the leading independent software support provider for Oracle and SAP products based on both the number of active clients supported and recognition by industry analyst firms. Over the years, as our reputation for technical capability, value, innovation, responsiveness and trusted reliability grew, clients and prospects began asking us to expand the scope of our support, product and service offerings to meet other current and evolving needs and opportunities related to their enterprise software. We also heard from prospects and clients that their goals include reducing the number of IT vendors to more manageable numbers from a governance perspective, with a desire to select vendors who can provide a wider scope of IT services and become true trusted partners. To meet the needs of our clients and prospects and to service what we believe is a significantly expanded addressable market opportunity, we designed, developed and are now delivering a new, expanded solutions portfolio (our "Solutions Portfolio") for a wider array of enterprise software – including an expanded list of supported software; managed services for Oracle, SAP, IBM, Salesforce and open-source database software; and new solutions for security, interoperability, observability and consulting. We also now offer an integrated package of our services as Rimini ONE™, a unique end-to-end, "turnkey" outsourcing option for Oracle and SAP landscapes designed to optimize our clients' existing technologies with a minimum of 15 extended years of operating lifespan and enable our clients to focus their IT talent and budget on potentially higher-value, innovative projects that will support competitive advantage and growth.

About Non-GAAP Financial Measures and Certain Key Metrics To provide investors and others with additional information regarding Rimini Street's results, we have disclosed the following non-GAAP financial measures and certain key metrics. We have described below Active Clients, Annualized Recurring Revenue and Revenue Retention Rate, each of which is a key operational metric for our business. In addition, we have disclosed the following non-GAAP financial measures: non-GAAP operating income, non-GAAP net income, EBITDA, Adjusted EBITDA and Billings. Rimini Street has provided in the tables above a reconciliation of each non-GAAP financial measure used in this earnings release to the most directly comparable GAAP financial measure. A reconciliation of Adjusted EBITDA is not available on a forward-looking basis because the Company is unable to predict its net income with reasonable certainty due to the effects of foreign currency exchange rates, income tax provisions, future interest rates on our variable rate indebtedness, the non-cash component of employee compensation expense, changes in its working capital and financing needs, and other such items without unreasonable effort. Similarly, the high variability of certain expense items renders us unable to provide a reconciliation to the guidance as to margin and selected expenses as a percentage of revenue presented in our earnings conference call. These items, which depend on various factors and could be material to the Company's results computed in accordance with GAAP, are uncertain. Due to a valuation allowance for our deferred tax assets, there were no tax effects associated with any of our non-GAAP adjustments. These non-GAAP financial measures are also described below. The primary purpose of using non-GAAP measures is to provide supplemental information that management believes may prove useful to investors and to enable investors to evaluate our results in the same way management does. We also present the non-GAAP financial measures because we believe they assist investors in comparing our performance across reporting periods on a consistent basis, as well as comparing our results against the results of other companies, by excluding items that we do not believe are indicative of our core operating performance. Specifically, management uses these non-GAAP measures as measures of operating performance; to prepare our annual operating budget; to allocate resources to enhance the financial performance of our business; to evaluate the effectiveness of our business strategies; to provide consistency and comparability with past financial performance; to facilitate a comparison of our results with those of other companies, many of which use similar non-GAAP financial measures to supplement their GAAP results; and in communications with our board of directors concerning our financial performance. Investors should be aware however, that not all companies define these non-GAAP measures consistently. Billings represents the change in deferred revenue for the current period plus revenue for the current period. Active Client is a distinct entity that purchases our services to support a specific product, including a company, an educational or government institution, or a business unit of a company. For example, we count as two separate active clients when support for two different products is being provided to the same entity. We believe that our ability to expand our active clients is an indicator of the growth of our business, the success of our sales and marketing activities, and the value that our services bring to our clients. Annualized Recurring Revenue is the amount of subscription revenue recognized during a fiscal quarter and multiplied by four. This gives us an indication of the revenue that can be earned in the following 12-month period from our existing client base assuming no cancellations or price changes occur during that period. Subscription revenue excludes any non-recurring revenue, which has been insignificant to date. Revenue Retention Rate is the actual subscription revenue (dollar-based) recognized over a 12-month period from customers that were clients on the day prior to the start of such 12-month period, divided by our Annual Recurring Revenue as of the day prior to the start of the 12-month period. Non-GAAP Operating Income is operating income adjusted to exclude: litigation costs and related recoveries, net, stock-based compensation expense and impairment charge related to operating right-of-use assets. The exclusions are discussed in further detail below. Non-GAAP Net Income is net income adjusted to exclude: litigation costs and related recoveries, net, loss on change in fair value of redeemable warrants, stock-based compensation expense and impairment charge related to operating right-of-use assets. These exclusions are discussed in further detail below. Specifically, management is excluding the following items from its non-GAAP financial measures, as applicable, for the periods presented: Litigation Costs and Related Recoveries, Net: Litigation costs and the associated insurance and appeal recoveries related to outside costs of litigation activities. These costs and recoveries reflect the ongoing litigation we are involved with, and do not relate to the day-to-day operations or our core business of serving our clients. Loss on Change in Fair Value of Redeemable Warrants: We have excluded the losses on redeemable warrants related to the change in fair value of these instruments given the financial nature of this fair value requirement. We are not able to manage these amounts as part of our business operations nor are the costs core to serving our clients, and therefore we have excluded them. Stock-Based Compensation Expense: Our compensation strategy includes the use of stock-based compensation to attract and retain employees. This strategy is principally aimed at aligning the employee interests with those of our stockholders and to achieve long-term employee retention, rather than to motivate or reward operational performance for any particular period. As a result, stock-based compensation expense varies for reasons that are generally unrelated to operational decisions and performance in any particular period. Impairment Charges Related to Operating Lease Right-of-Use Assets: This relates to impairment charges on our leased assets for a portion of one of our locations as we no longer use the space and have revised our estimated loss. Reorganization Costs: The costs consist primarily of severance costs associated with the Company's reorganization plan. EBITDA is net income adjusted to exclude: interest expense, income tax expense, and depreciation and amortization expense. Adjusted EBITDA is EBITDA adjusted to exclude: litigation costs and related recoveries, net, loss on change in fair value of redeemable warrants, stock-based compensation expense, impairment charges related to operating right- of-use assets and reorganization costs, each as discussed above.
