Michael Mauboussin’s’s framework for understanding free cash flow. 10 lessons for investors.
By Vlad from Bastion on
1. A company’s value is the present value of its future free cash flow. Free cash flow is profit after taxes minus investments in growth, primarily capital expenditures. An investor’s job is to find the company that will ultimately generate the most FCF. But that FCF will not always be positive along the way.
2. Negative FCF is not always bad. If a company invests at a return above its cost of capital, it creates value. People love posting charts showing negative FCF at the hyperscalers. What matters is the return those investments will generate over the following years.
3. The Walmart lesson. From 1973 to 1986, Walmart had negative FCF for 14 consecutive years because it invested aggressively in expansion. Its return on invested capital averaged about 18%, well above its cost of capital. The stock returned 33% annually, three times the return of the S&P 500. Negative FCF was a sign of growth, not weakness.
4. Focus on investment returns, not the minus sign. The key question is whether revenue and profit are keeping pace with capital expenditures. If profit grows faster than investment, value is being created. If it falls behind, cash is being destroyed.
5. Watch return on incremental invested capital (ROIIC). It measures the return generated by each new dollar invested. If ROIIC is above the company’s current average return on capital, its overall return should rise. If it is lower, the average should fall. Hyperscalers’ combined ROIIC is currently near its peak at more than 35%, compared with a cost of capital of about 8%.
6. Subtract stock-based compensation. Paying employees with shares is effectively a combination of issuing stock and paying wages. If SBC is properly deducted from operating cash flow, the reported cash flow of large technology companies falls by 10% to 20%. Many investors ignore this and overstate the true figure.
7. A mature company can return to growth. A sharp increase in capital expenditures can move a business back to an earlier stage of its life cycle. Alphabet, Meta, and Oracle moved from “maturity” to “growth” after accelerating data center construction. This is not deterioration. It is a new investment phase.
8. The current decline in hyperscaler cash flow is expected to be temporary. Combined FCF for Amazon, Alphabet, Microsoft, Meta, and Oracle falls from $170 billion in early 2024 to negative $265 billion in 2027. Consensus then expects it to recover to ~$505 billion by 2030. Returns on capital remain above the cost of capital throughout this period. Microsoft is the only hyperscaler expected to maintain positive FCF across the entire forecast horizon.
9. Returns arrive with a delay, so patience matters. Amazon CEO Andy Jassy explained it directly. During periods of rapid growth, capital expenditures rise faster than revenue. This weakens near-term cash flow. The returns appear a few years later, after the new capacity is operating and generating revenue. Investors who focus only on current cash flow see the worst part of the cycle.
