Roblox : First Quarter 2024 Shareholder Letter

To Our Shareholders:

Over the years we have shared that the Roblox business model has long-term healthy unit economics and thus the ability to generate significant cash flow. The first quarter of 2024 was a case in point - we delivered good topline growth and record amounts of operating and free cash flow.

During our Investor Day last November, we described two financial goals: topline growth of 20% or more year-over-year through 2027; and margin and cash flow improvements based on operating leverage and reductions in capital expenditures.

In Q1 2024, revenue grew by 22% year-over-year, and bookings grew at 19.4%. Net cash and cash equivalents provided by operating activities totaled $238.9 million in Q1 2024, a record for any quarter, and up 37% over Q1 2023. Free cash flow was $191.1 million in Q1 2024, also a record, and up 133% over Q1 2023. In fact, we generated over 50% more free cash flow in Q1 2024 than in all of 2023.

We are operating more efficiently. Over the past three quarters, year-over-year, we reduced Certain Infrastructure, Trust and Safety expenditures. We are realizing these savings from internal efficiency initiatives, the shift to more AI-driven moderation, and optimizing infrastructure. The quality of our platform is going up, while costs are going down.

Over the same time frame, we have reduced the growth rate of personnel costs, excluding stock-based compensation, by keeping headcount flat, and are taking steps to drive even more leverage over the balance of 2024. We are focusing our resources into the growth verticals of our business - namely advertising, AI, and live operations.

In addition, capital expenditures dropped by nearly 50% in Q1 2024 over the same quarter last year.

Due to seasonality, note that both cash flow figures will decline in Q2 and that is normal and expected (please see pp. 24-25 of our Supplemental Materials posted on ir.roblox.com). Our Q2 guidance implies, however, that through the first half of this year we will generate the levels of cash flow improvements, as compared to the first half of 2023, referenced during Investor Day last November.

Now let's turn to our key metrics:

• Daily Active Users ("DAUs") were 77.7 million and grew by 17% over Q1 2023. Growth remains notably strong among users aged 13 years and older, and DAUs grew across all regions with particular strength in APAC.
• Hours Engaged ("Hours") were 16.7 billion and grew 15% over Q1 2023. Similar to DAUs, growth remains strongest among users 13 years and older and in APAC.
• Revenue was $801.3 million in Q1 2024 and grew by 22% over revenue in Q1 2023. This was above our Q1 guidance range of $755 - $780 million.
• Bookings totaled $923.8 million and grew by 19% over bookings in Q1 2023. This was within our Q1 guidance range of $910 - $940 million.
• Consolidated net loss was $271.9 million, compared to a consolidated net loss of $269.9 million in Q1 2023. This was better than our Q1 net loss guidance range of $347 million - $342 million.
• Adjusted EBITDA was $6.9 million, better than our guidance range of $55 million - $50 million. Adjusted EBITDA excludes the adjustments for an increase in deferred revenue of $127.6 million and an increase in deferred cost of revenue of $32.9 million.
• Net cash and cash equivalents provided by operating activities was $238.9 million in Q1 2024, up 37% over Q1 2023, and free cash flow was $191.1 million in Q1 2024, an increase of 133% over Q1 2023.
• Our fully diluted share count, consisting primarily of shares issued and outstanding of Class A and Class B common stock, stock options outstanding, and unvested RSUs outstanding, was 718.6 million shares as of March 31, 2024, an increase of 3.2% as of March 31, 2023.
• Cash and cash equivalents, short-term investments, and long-term investments totalled $3,469 million as of March 31, 2024, up from $3,092 million as of March 31, 2023. Cash and cash equivalents, short-term investments, and long-term investments, net of debt, increased to $2,464 million as of March 31, 2024, up from $2,103 million as of March 31, 2023.

Engagement in Q1 exhibited an unseasonal decline and the impact was broad-based across regions, ages, and platforms. Our teams have been hard at work identifying opportunities to drive growth, and we have seen encouraging signs during the back half of April and early May with DAUs, Hours, and Bookings in the US & Canada back to around 20% year-over-year or higher.

In particular, our efforts on content discovery, platform events, economy, and app and platform performance have helped to increase recent growth:

During Q1 2024, we began experimenting with changes in our AI-driven discovery algorithm and the positioning of various content types on the Homepage, such as Friends, Continue, Recommended for You, Sponsored Experiences, People You May Know, and Today's Picks. Today's Picks is a new curated sort that features up-and-coming creations, updated experiences, and new genres helping our users to try more experiences and increasing the diversity of the content with which they engage.

In response to community feedback, we reintroduced platform-wide events in Q1 as well. The Hunt: First Edition ran for two weeks starting on March 15 on mobile, PC, console, and VR. We were pleased with the results of the event and believe it led to incremental engagement, re-engaged users, and surfaced new content. Going forward, we will continue our new series of events and explore fresh themes and ideas, while also investing in better tooling to enable creators and brands to run their own live operations and events.

Starting in February, our economy team launched dynamic price floors in our Marketplace on certain Avatar items. As a result, average prices for items and overall spend increased.

Finally, we continued to improve performance for our app and experiences. In particular, we've made progress in improving frame rates, increasing stability across all platforms (especially Windows Desktop) and enhancing graphics quality on higher end devices.

Based on results since the middle of April, we believe that these steps are having positive results.

Brand Partnerships & Advertising

We have continued to make progress with respect to our brand partnerships and advertising roadmap.

• On April 10, we announced a partnership with PubMatic to tap into their vast demand, including supply path optimization deals with advertising agencies and premium brands.
• On April 29, we initiated our first real-world shopping test with Walmart - one of multiple tests we are planning with different brands.
• On May 1, we announced video ads would become available to all advertisers through our self-serve Ads Manager and soon through our programmatic partners. We have been testing video ads with top brands and global agencies, and early results are promising.

Independent measurement is critical to advertisers, which is why we recently announced a partnership with IAS, an industry-leadingthird-party measurement provider, to verify that our Immersive Ads are driving engagement with users. We are also offering a brand lift solution with Kantar Context Lab, and in the future we will also provide measurement with multiple brand lift partners using industry-standard passive measurement of ad campaigns.

In tandem with this progress, our team has been hard at work educating the market and establishing a foundation for scalable revenue. We attended both PlayFronts and NewFronts for the first time this year and generated significant interest in our suite of advertising products.

Finally, we continue to hire key talent on our brands and advertising team and want to welcome David Vespe as our new Head of Ads Engineering. David joins us following nearly two decades at Google where he built some of Google's most successful ads businesses across Search, YouTube and Social.

Guidance:

Our Q2 2024 bookings guidance incorporates slower growth in the first half of April as we lapped comparisons with the Easter holiday last year, but also includes recent evidence of improved growth in DAUs, Hours, Revenue, and Bookings. For the full year, we are basically matching the bookings growth rate we expect to achieve in 1H 2024, with an adjustment down to account for a strong Q4 2023 that included the Playstation launch which we will lap this year.

Despite lowering bookings expectations by approximately 4% for the full year versus our prior guidance, by continuing to manage our fixed costs and capital expenditures, we believe we can deliver the same amount of operating and free cash flow implied by our guidance last quarter.

Finally, we will no longer refer to Covenant Adjusted EBITDA in our shareholder letters and earnings press releases though we will calculate it in the liquidity sections of our 10-Q and 10-K. We will continue to guide to Adjusted EBITDA which excludes adjustments for the change in deferred revenue and deferred cost of revenue. We will separately guide to and report the change in deferred revenue and deferred cost of revenue. By adding those changes in deferrals as adjustments to Adjusted EBITDA it should foot with the EBITDA figures most analysts have in their financial models.

Management guidance is as follows:

Q2 2024:

• Revenue between $855 million - $880 million.1
• Bookings between $870 million - $900 million.
• Consolidated net loss between $267 million - $265 million.
• Adjusted EBITDA between $36 million - $38 million, which excludes adjustments for:
• • Increase in deferred revenue between $18 million - $23 million.
  • Increase in deferred cost of revenue between $7 million - $9 million.
  • The total of these changes in deferrals between $11 million - $14 million.
• Net cash and cash equivalents provided by operating activities between $61 million - $68 million.
• Capital expenditures and purchases of intangible assets of approximately $45 million.
• Free cash flow between $16 million - $23 million.

• Our revenue guidance assumes a one month reduction in the estimated average lifetime of a paying user from 28 months to 27 months, beginning April 1, 2024. This change in estimate is reflected in our Q2 2024 GAAP and non-GAAP guidance. Based on the carrying amount of deferred revenue and deferred cost of revenue as of March 31, 2024, the April 1, 2024 change in the estimated average lifetime of a paying user will result in an increase in revenue and cost of revenue of $58.9 million and $12.4 million, respectively, during the second quarter of 2024.

Fiscal 2024:

• Revenue between $3,450 million - $3,525 million.2
• Bookings between $4,000 million - $4,100 million.
• Consolidated net loss between $1,096 million - $1,044 million.
• Adjusted EBITDA between $95 million - $147 million, which excludes adjustments for:
• • Increase in deferred revenue between $568 million - $593 million.
  • Increase in deferred cost of revenue between $133 million - $140 million.
  • The total of these changes in deferrals between $435 million - $453 million.
• Net cash and cash equivalents provided by operating activities between $530 million - $600 million.
• Capital expenditures and purchases of intangible assets of approximately $180 million.
• Free cash flow between $350 million - $420 million.

• Our revenue guidance assumes a one month reduction in the estimated average lifetime of a paying user from 28 months to 27 months, beginning April 1, 2024. This change in estimate is reflected in our updated full year 2024 GAAP and non-GAAP guidance. Based on the carrying amount of deferred revenue and deferred cost of revenue as of March 31, 2024, the April 1, 2024 change in estimated average lifetime of a paying user will result in an increase in revenue and cost of revenue of $98.0 million and $20.4 million, respectively, during the full year 2024.
