REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the stockholders and the Board of Directors of Roblox Corporation

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Roblox Corporation and subsidiaries (the “Company”) as of December 31, 2025 and 2024, the related consolidated statements of operations, comprehensive loss, stockholders’ equity, and cash flows, for each of the three years in the period ended December 31, 2025, and the related notes (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2025 and 2024, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2025, in conformity with accounting principles generally accepted in the United States of America.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company’s internal control over financial reporting as of December 31, 2025, based on criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated February 11, 2026, expressed an unqualified opinion on the Company’s internal control over financial reporting.

Basis for Opinion

These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matter

The critical audit matter communicated below is a matter arising from the current-period audit of the financial statements that was communicated or required to be communicated to the Audit and Compliance Committee and that (1) relates to accounts or disclosures that are material to the financial statements and (2) involved especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

Revenue Recognition — Refer to Note 1 to the financial statements

Critical Audit Matter Description

The Company derives substantially all of its revenue from the sale of virtual items on the Roblox platform. The Company’s performance obligation when selling virtual items to users is to provide those users with the ability to acquire, use, and hold virtual items on the Roblox platform over the estimated period of time the virtual items are available to the user, which is estimated as the average lifetime of a paying user (“customer life” for durable virtual items) or until the virtual items are consumed (for consumable virtual items). To separately identify, and account for consumable and durable virtual items, the Company specifically categorizes each purchase for the majority of virtual items purchased on the Roblox platform. For the remaining population, the Company estimates the amount of consumable and durable virtual items purchased based on data from specifically categorized purchases and the expected behavior of the users within similar experiences.

Significant judgement is exercised by management when (1) estimating the customer life, which includes analyzing the most recent trends in player cohort activities and (2) estimating the amount of consumable and durable virtual items purchased for the remaining population of purchases that are not specifically categorized (“remaining population allocation”), which includes evaluating and estimating the expected behavior of users in the population using information from known purchases in similar experiences.

Given the complexity of estimating the customer life and the remaining population allocation, auditing these estimates required a high degree of auditor judgement and increased extent of effort when performing audit procedures to evaluate the Company’s judgements and conclusions.

How the Critical Audit Matter Was Addressed in the Audit

Our audit procedures related to the Company’s estimated customer life and remaining population allocation included the following, among others:

•We obtained an understanding of the Company’s methodology for developing the estimated customer life and remaining population allocation.

•We tested the effectiveness of internal controls related to the review of the methodology and assumptions used in estimating the customer life and remaining population allocation, including the review of inputs and assumptions.

•For the customer life estimate, we (1) tested the accuracy and completeness of the historical monthly retention data for player cohorts, (2) tested the mathematical accuracy of the Company’s calculations to project future retention, and (3) assessed the impact of qualitative factors to evaluate management’s judgement on future retention utilizing competitor information that is publicly available and most recent historical trends in cohort activity.

•For the remaining population allocation estimate, we (1) tested the underlying data for specifically categorized purchases used in management’s analysis by selecting a sample of virtual items that were purchased as well as a sample of items from the Roblox platform and tested that such items were properly categorized between a consumable or a durable virtual item, (2) tested the mathematical accuracy of the percentage of consumable and durable goods for the specifically categorized purchases, (3) compared the composition of the virtual items purchased that were specifically categorized to those that were not specifically categorized to evaluate if the nature of the goods are similar, and (4) tested that the percentage of consumable and durable virtual items for the specifically categorized purchases was applied to the remaining population.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated financial statements as of and for the year ended December 31, 2025, of the Company and our report dated February 11, 2026, expressed an unqualified opinion on those financial statements.

Basis for Opinion

The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.
