Roblox Corporation (RBLX) Cash Flow Statement

The persistent gap between net income and operating cash flow is stark: OCF/NI ratios have been negative throughout, but the magnitude of divergence is widening. In 2026Q2, OCF of $318M against a -$183M net loss implies a cash conversion of roughly 274% of absolute loss, almost entirely attributable to non-cash charges like SBC ($282M) and D&A ($65M). This suggests that while GAAP profitability remains elusive, the underlying cash-generative nature of the platform is improving, though investors should monitor whether working capital tailwinds reverse.

The FCF trajectory is erratic, with negative capex adjustments in some quarters (e.g., -$298.4M in 2025Q4) inflating FCF, but the underlying trend is positive: the 2026Q2 FCF of $351M is triple the year-ago quarter's $176.7M. FCF margins have expanded from 12.5% in 2024Q2 to 23.9% in 2026Q2, though the 41%+ margins in 2026Q1 and 2025Q3 are likely unsustainable due to working capital timing. This suggests improving operational efficiency, but the lumpiness warrants caution in extrapolating quarterly figures.

CapEx/Revenue has consistently been in the low single digits, with the exception of 2025Q4's 21.1% spike (likely a one-time infrastructure investment). This suggests that RBLX's growth is driven by platform investments and content rather than physical assets, aligning with its digital nature. The negative capex figures in several quarters (e.g., -$33M in 2026Q1) are unusual and may reflect timing of asset sales or accounting adjustments, but the overall capital intensity is minimal, implying that FCF is largely a function of working capital and non-cash charges.

The working capital line is the primary driver of OCF volatility, with swings of over $500M quarter-over-quarter. This likely reflects the timing of deferred revenue recognition and payments to developers, which are large for a platform like RBLX. The cumulative positive contribution over the last year suggests that the company is effectively managing its collections and payables, but the magnitude of swings indicates that investors should not rely on quarterly OCF as a stable metric. The negative WC change in 2026Q2 may signal a reversal of prior tailwinds, warranting close monitoring.

After a year of no buybacks, the $375M repurchase in 2026Q2 is a notable deployment of cash, funded by the strong OCF of $318M and existing cash reserves. This suggests management confidence in the cash-generative capacity of the business, despite ongoing GAAP losses. With no dividends and minimal acquisition activity, the buyback is the primary capital return mechanism, but its sustainability depends on maintaining positive OCF and managing working capital volatility.

The cumulative gap between net income and OCF is enormous, with OCF exceeding net income by $6.0B over the period. This is primarily due to stock-based compensation ($2.66B cumulative) and working capital inflows ($1.93B cumulative), which have masked the underlying cash generation. While this divergence is typical for high-growth tech companies, it raises questions about the sustainability of SBC levels and whether working capital tailwinds will persist. The cash flow statement reveals a business that is cash-generative on an operating basis, but the quality of that cash flow is heavily reliant on non-cash charges and timing.
