Both companies are not currently offering dividends, reflecting a need for reinvestment to stabilize their operations. The substantial negative ROE and ROIC for both firms raise significant concerns regarding profitability and returns on invested capital.
Dividend and Shareholder Returns
Both Ambarella, Inc. (AMBA) and Ouster, Inc. (OUST) do not pay dividends, which reflects their current negative net income and ongoing reinvestment strategies aimed at growth. This approach suggests a prioritization of research and development, potentially aligning with long-term shareholder value creation.
