Sunrun  (WBO:RUN) Cyclically Adjusted FCF per Share Explanation

If a company grows much fast than inflation, Cyclically Adjusted FCF per Share may underestimate the company's free cash flow. Cyclically Adjusted Price-to-FCF can seem to be too high even the actual Price-to-Free-Cash-Flow is low.

For the Cyclically Adjusted Price-to-FCF, the free cash flow per share of the past 10 years are inflation-adjusted and averaged. The result is used for P/FCF calculation. Since it looks at the average over the last 10 years, the Cyclically Adjusted Price-to-FCF is also called CAPFCF Ratio.

The Shiller PE Ratio was first used by professor Robert Shiller. He uses E10 for his Shiller PE Ratio calculation. E10 is the average of the inflation adjusted earnings per share of a company over the past 10 years. The similar calculation is applied by GuruFocus to calculate the Cyclically Adjusted Price-to-FCF.

Sunrun Cyclically Adjusted FCF per Share Calculation

E10 is a concept invented by Prof. Robert Shiller, who uses E10 for his Shiller PE Ratio calculation. E10 is the average of the inflation adjusted earnings of a company over the past 10 years. The similar calculation is applied by GuruFocus to calculate the Cyclically Adjusted FCF per Share and the Cyclically Adjusted Price-to-FCF. The Cyclically Adjusted FCF per Share is the average of the inflation adjusted Free Cash Flow per Share of a company over the past 10 years.

What is Cyclically Adjusted FCF per Share? How do we calculate Cyclically Adjusted FCF per Share?

Cyclically Adjusted FCF per Share is the average of the inflation adjusted Free Cash Flow per Share of a company over the past 10 years. Let's use an example to explain.

If we want to calculate the Cyclically Adjusted FCF per Share of Wal-Mart (WMT) for Dec. 31, 2010, we need to have the inflation data and the free cash flow per share from 2001 through 2010.

We adjusted the 2001 free cash flow per share data with the total inflation from 2001 through 2010 to the equivalent free cash flow in 2010. If the total inflation from 2001 to 2010 is 40%, and Wal-Mart's free cash flow is $1 a share in 2001, then the 2001's equivalent free cash flow in 2010 is $1.4 a share. If Wal-Mart's free cash flow is $1 again in 2002, and the total inflation from 2002 through 2010 is 35%, then the equivalent 2002 free cash flow in 2010 is $1.35. So on and so forth, you get the equivalent free cash flow per share of past 10 years. Then you add them together and divided the sum by the count to get Cyclically Adjusted FCF per Share.

Please note that we use the CPI data of the country/region where the company is headquartered. If the CPI data for that country/region is not available, then we will use the CPI data of the United States as default.

For example, Sunrun's adjusted Free Cash Flow per Share data for the three months ended in Mar. 2026 was:

Adj_FreeCashFlowPerShare= Free Cash Flow per Share /CPI of Mar. 2026 (Change)*Current CPI (Mar. 2026)
=-1.316/330.2130*330.2130
=-1.316

Current CPI (Mar. 2026) = 330.2130.
