Roblox Corporation (NYSE: RBLX) delivered a Q2 of contrasts. Revenue of $1.47 billion beat the $1.08 billion prior-year figure by 36% and topped the $1.6 billion consensus estimate on an adjusted basis. But the headline number masks a deeper problem: bookings growth of just 8% year-over-year landed at the low end of the company's own guidance range. Management is now guiding for a 14-18% year-over-year decline in Q3 bookings. The stock will likely face pressure as investors digest the implications of a platform growing users but struggling to monetize them.
DAUs reached 123 million, up 10% year-over-year, and hours engaged hit 29 billion, up 5%. International growth was robust. Japan and India posted DAU growth of 67% and 64%, respectively. But the U.S. and Canada, Roblox's most mature and highest-monetizing market, saw hours grow only 1%. Global expansion is masking a domestic monetization problem.
Management points to a mix shift in engagement. Users are moving away from high-monetizing viral games from 2025 toward newer and evergreen titles with lower hourly monetization. This was compounded by changes to the "Recommended For You" (RFY) algorithm, which now optimizes for 28-day retention rather than near-term monetization. The impact was most pronounced among younger U.S. cohorts, where the algorithm change reduced per-hour spend more than anticipated. Management's internal testing suggests longer retention will eventually offset the monetization dip. Q3 guidance suggests the pain is far from over.
Q3 guidance is the real story, and it's not pretty. The company expects bookings of $1.576 billion to $1.653 billion, a 14-18% year-over-year decline. Revenue is expected to grow 4-10% to $1.413-$1.490 billion, but that's a function of the 27-month deferred revenue recognition policy, not underlying strength. Adjusted EBITDA is guided to just $0-$41 million, a sharp drop from the $152 million reported in Q2. Free cash flow is expected to range from negative $60 million to positive $5 million, reflecting back-half-loaded capital expenditures and a $40 million working capital headwind from creator payout timing.
Roblox also withdrew its full-year guidance, accelerating its previously announced transition to quarterly-only outlooks by one quarter. Management's rationale is that annual guidance is "not a helpful tool for investors" given the non-linear trajectory of growth and the timing of investments. That's a defensible position. It also removes a key anchor for the sell-side and leaves investors with a murky picture for the back half of the year.
The company announced a $3 billion share repurchase program, with $1 billion planned over the next 12 months. In Q2, it repurchased $380 million worth of stock. The buyback signals confidence in the long-term thesis, but its timing is curious given the near-term headwinds. With the stock down on the guidance, the company is effectively buying at a discount. The buyback pace looks aggressive given the deteriorating bookings trajectory and the $6.1 billion cash position that needs to fund AI investments, the Morpheus AI acquisition, and the Build platform rollout.
Cost structure is worth watching. Infrastructure and trust & safety expenses grew 54% year-over-year to $236 million, driven by AI-related investments and safety marketing. Personnel costs excluding stock-based compensation grew 16% to $283 million. These are fixed-cost investments that will deleverage if bookings decline as guided. The Q3 Adjusted EBITDA range of $0-$41 million implies significant margin compression from Q2's $152 million, even as revenue grows modestly.
The strategic initiatives are ambitious. Build, the prompt-based game creation tool, is in public alpha in New Zealand. Moments, the short-form video discovery tab, is rolling out to age-checked users over 16. The expansion into 2D gaming and the Morpheus AI acquisition for photorealistic gaming are multi-year bets. These are long-term growth drivers that do nothing to address the near-term monetization headwinds. The question investors should be asking is whether the algorithm changes and safety initiatives are structurally depressing monetization per hour, or whether this is a temporary transition to a healthier, more diversified platform.
Management's conviction in 20%+ compounded top-line growth over the long term remains unchanged. The Q3 guide is a stark reminder that the path to that growth will be non-linear and, at times, painful. For now, the market is being asked to look through a 14-18% bookings decline and a withdrawal of annual guidance, trusting that algorithmic optimization and platform investments will pay off. That's a lot to ask, even for a company with 123 million DAUs and a $34.8 billion market cap.
