Corporate decisions about repurchasing shares hinge on cash flow realities and long-term value creation. Evidence-based guidance from practitioners and academics clarifies when buybacks are financially prudent and when they risk harming the firm’s prospects. Aswath Damodaran New York University Stern School of Business emphasizes grounding buyback programs in sustainable free cash flow rather than transient gains from asset sales or accounting adjustments, while Lucian Bebchuk Harvard Law School highlights governance and distributional implications when buybacks replace productive investment.
Assessing sustainable free cash flow
The primary cash flow consideration is whether the firm generates recurring free cash flow after funding normal operations and required capital expenditures. Free cash flow measures operating cash flow less reinvestment needs and reflects what management can return without compromising growth. Firms should examine multi-year cash flow patterns and stress test projections under slower revenue growth or higher interest costs. A one-time cash inflow or temporary margin spike should not be treated as a new baseline for buybacks, because repeating distributions in weaker conditions can force asset sales or layoffs.
