© GitLab Inc. This presentation contains “forward-looking statementsˮ within the meaning of the safe harbor provisions of the Private Securities Litigation Reform Act of 1995. All statements other than statements of historical fact are forward-looking statements. These statements include, but are not limited to, statements regarding our future operating results and financial position, anticipated future expenses and investments, expectations relating to certain of our key financial and operating metrics, our business strategy and plans, market growth, our market position and potential market opportunities, and our objectives for future operations. The words “believe,ˮ “may,ˮ “will,ˮ “estimate,ˮ “potential,ˮ “continue,ˮ “anticipate,ˮ “intend,ˮ “expect,ˮ “could,ˮ “would,ˮ “project,ˮ “plan,ˮ “target,ˮ “expect,ˮ and similar expressions are intended to identify forward-looking statements. Forward-looking statements are based on managementʼs expectations, assumptions, and projections based on information available at the time the statements were made. Our future financial condition and results of operations, as well as any forward-looking statements, are subject to change due to inherent risks and uncertainties, many of which are beyond our control. Important factors that could cause our actual results, performance and achievements, or industry results to differ materially from estimates or projections contained in or implied by our forward-looking statements include the following: our ability to effectively manage our growth; our revenue growth rate in the future; our ability to achieve and sustain profitability; our business, financial condition, and operating results; security and privacy breaches; intense competition in our markets and loss of market share to our competitors; our ability to respond to rapid technological changes; the market for our services may not grow; a decline in our customer renewals and expansions; fluctuations in our operating results; our incorporation of artificial intelligence features into our products; our transparency; our publicly available company Handbook; customers staying on our open-source or free SaaS product offering; our ability to accurately predict the long-term rate of customer subscription renewals or adoption, or the impact of these renewals and adoption; and our hiring model. We do not undertake any obligation to update or release any revisions to any forward-looking statement or to report any events or circumstances after the date hereof or to reflect the occurrence of unanticipated events, except as required by law. This presentation also contains estimates and other statistical data made by independent parties and by GitLab relating to market size and growth and other industry data. Such data involves a number of assumptions and limitations, and you are cautioned not to give undue weight to such estimates. GitLab has not independently verified the statistical and other industry data generated by independent parties and contained in this presentation and, accordingly, it cannot guarantee their accuracy or completeness. In addition, projections, assumptions and estimates of its future performance and the future performance of the markets in which GitLab competes are necessarily subject to a high degree of uncertainty and risk due to a variety of factors. These and other factors could cause results or outcomes to differ materially from those expressed in the estimates made by the independent parties and by GitLab. This presentation includes certain financial measures not presented in accordance with generally accepted accounting principles in the United States ("GAAP"), which are used by management as a supplemental measure, have certain limitations, and should not be construed as alternatives to financial measures determined in accordance with GAAP. The non-GAAP measures as defined by us may not be comparable to similar non-GAAP measures presented by other companies. Our presentation of such measures, which may include adjustments to exclude unusual or non-recurring items, should not be construed as an inference that our future results will be unaffected by other unusual or non-recurring items. A reconciliation is provided in the Appendix to the most directly comparable financial measure stated in accordance with GAAP. For further information with respect to GitLab, we refer you to our most recent Annual Report on Form 10K and Quarterly Reports on Form 10Q filed with the SEC. In addition, we are subject to the information and reporting requirements of the Securities Exchange Act of 1934 and, accordingly file periodic reports, current reports, proxy statements and other information with the SEC.

© GitLab Inc. 3 insights from our Executive Advisory Board Agents are like psychopathic interns. They lack good judgement. A human could go to jail for certain decisions. What about an agent? — Head of engineering, major technology platform “ These pain points illustrate where the market is heading and GitLabʼs growing value proposition GitLab's value is two-fold: cloud, model, and tool neutrality — and everything that happens around code generation: tests, controls, governance. — Head of software engineering, Top-10 US bank “ We can no longer configure governance project by project. We need mission control logic — policy injected at the platform level across the entire estate. — EAB customer, 200,000+ repositories “ “““

© GitLab Inc. Definitions Customer: A single organization with separate subsidiaries, segments, or divisions that use the GitLab platform is considered a single customer for determining each organizationʼs ARR. Reseller or distributor channel partners are not counted as customers. In cases where customers subscribe to the GitLab platform through our channel partners, each end customer is counted separately. Base Customers: Customers generating $5,000 or more in ARR. Monthly Recurring Revenue (“MRRˮ): Aggregate monthly revenue for all customers during that month from committed contractual amounts of subscriptions, including self-managed and SaaS offerings but excluding professional services. Annual Recurring Revenue (“ARRˮ): Monthly recurring revenue multiplied by 12. Current Period ARR Includes any upsells, price adjustments, user growth within a customer, contraction, and attrition. Dollar-Based Net Retention Rate: The percentage change in ARR derived from the customer base at a point in time. Calculated as of a period end by starting with customers as of 12 months prior to such period end (“Prior Period ARRˮ). Then ARR for the same customers is calculated as of the current period end (“Current Period ARRˮ). Current Period ARR includes any upsells, price adjustments, user growth within a customer, contraction, and attrition. Current Period ARR is then divided by the total Prior Period ARR to arrive at the Dollar-Based Net Retention Rate. Run-Rate Revenue: The sum of the most recent three months of revenue at the end of each quarter multiplied by 4.
