In Q4'25, OKLO's Operating Cash Flow reached -$33.4M USD, marking a substantial deterioration from the -$18.0M USD reported in Q3'25 and reflecting ongoing operational challenges. Free Cash Flow performed even worse at -$60.4M USD, a sharp increase in outflow compared to -$23.1M USD in the prior quarter, highlighting intensified capital expenditures or investments during this period. Over the timeframe from Q1'23 to Q4'25, both Operating and Free Cash Flow have exhibited a consistent downward trend, with outflows escalating from modest levels of around -$0.7M USD in Q1'23 to over $60M USD by Q4'25, indicating growing cash burn amid expansion efforts. Notable acceleration occurred post-Q4'24, where quarterly deficits for Operating Cash Flow more than doubled in subsequent periods, while Free Cash Flow showed heightened volatility, particularly in Q4'25, underscoring potential liquidity pressures for the company. This bar chart visualization emphasizes the negative trajectory, with no periods of positive cash generation observed.
