In Q4'25, GOOGL's operating cash flow reached $52.4B, marking a robust increase from $48.4B in Q3'25 and representing the highest quarterly figure in the observed period. Free cash flow for the same quarter stood at $24.6B, up from $24.5B in Q3'25, reflecting strong liquidity generation despite ongoing capital expenditures. Over the period from Q1'23 to Q4'25, operating cash flow exhibited an overall upward trend, starting at $23.5B and peaking at $52.4B, with notable volatility including a dip to $18.9B in Q4'23 before consistent recovery and acceleration in 2024-2025. Free cash flow followed a similar pattern but with greater fluctuations, declining to $5.3B in Q2'25 amid higher investments, yet rebounding sharply to support sustained growth; both metrics underscore improving operational efficiency and cash generation capacity for the company.
