Magnite, Inc. (MGNI) Cash Flow Statement

The OCF/NI ratio of 9.64x in 2026Q2 is inflated by a $133.8M working capital benefit, while 2026Q1 saw a -27.37x ratio due to a $156.4M working capital drain. This extreme volatility suggests that reported net income is not a reliable indicator of cash generation, and investors should focus on the underlying operating cash flow trends. The large working capital swings may reflect seasonal payment terms with publishers and advertisers, but the magnitude warrants close monitoring.

The FCF trajectory is highly erratic, with 2026Q2's 92.4% margin contrasting sharply with 2026Q1's -81.5%. This volatility is driven by working capital changes, not just seasonality, as 2025Q4 also showed a strong 48.4% margin. The reported net income of $19.4M in 2026Q2 is far below FCF, suggesting that cash generation is not yet translating into consistent profitability, and the company's ability to sustain such high FCF margins is uncertain.

The capital intensity is relatively low for a tech platform, but the increase to 12.4% in 2025Q4 suggests management is investing in growth, possibly for CTV infrastructure. However, the absolute CapEx amounts are modest ($12-25M per quarter), and the company's high fixed-cost base is more driven by cloud and data center costs, which are expensed rather than capitalized. This implies that reported CapEx may understate the true capital requirements of the business.

The working capital swings are the primary driver of the cash flow volatility, with 2026Q1's negative change and 2026Q2's positive change nearly offsetting each other. This pattern suggests that the company's cash conversion cycle is highly sensitive to the timing of advertiser payments and publisher payouts, which may be influenced by seasonal ad spend. Investors should monitor whether these swings are purely seasonal or indicate a structural issue in the company's ability to manage its balance sheet efficiently.

The company has consistently repurchased shares each quarter, with amounts ranging from $3.7M to $23.4M, even during periods of negative FCF. This suggests management is confident in the long-term cash generation, but it also reduces liquidity during downturns. The lack of dividends and the focus on buybacks may indicate a belief that the stock is undervalued, but the timing of buybacks during cash flow troughs could be suboptimal.

The cumulative gap of $347.1M between operating cash flow and net income suggests that non-cash charges like D&A and SBC, along with working capital benefits, are boosting cash flow. However, this divergence also raises questions about the sustainability of such cash generation, as working capital swings can reverse. The company's ability to convert earnings into cash appears strong, but the quality of that conversion is volatile, and investors should be cautious about extrapolating the cumulative trend.
