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.

Realtek Semiconductor's adjusted free cash flow per share for the three months ended in Jun. 2026 was $0.990. Add all the adjusted free cash flow per share for the past 10 years together and divide the count will get our Cyclically Adjusted FCF per Share, which is $2.38 for the trailing ten years ended in Jun. 2026.

During the past 12 months, Realtek Semiconductor's average Cyclically Adjusted FCF Growth Rate was 9.40% per year. During the past 3 years, the average Cyclically Adjusted FCF Growth Rate was 16.60% per year. During the past 5 years, the average Cyclically Adjusted FCF Growth Rate was 18.50% per year. Please click Growth Rate Calculation Example (GuruFocus) to see how GuruFocus calculates Wal-Mart Stores Inc (WMT)'s revenue growth rate. You can apply the same method to get the Cyclically Adjusted FCF Growth Rate using Cyclically Adjusted FCF per Share data.

During the past 13 years, the highest 3-Year average Cyclically Adjusted FCF Growth Rate of Realtek Semiconductor was 25.20% per year. The lowest was 16.60% per year. And the median was 20.10% per year.

As of today (2026-08-19), Realtek Semiconductor's current stock price is $70.00. Realtek Semiconductor's Cyclically Adjusted FCF per Share for the quarter that ended in Jun. 2026 was $2.38. Realtek Semiconductor's Cyclically Adjusted Price-to-FCF of today is 29.41.

During the past 13 years, the highest Cyclically Adjusted Price-to-FCF of Realtek Semiconductor was 49.55. The lowest was 14.34. And the median was 25.93.


Realtek Semiconductor  (LUX:RTKSM) 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. 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.

Realtek Semiconductor's Cyclically Adjusted Price-to-FCF of today is calculated as

Cyclically Adjusted Price-to-FCF=Share Price/Cyclically Adjusted FCF per Share
=70.00/2.38
=29.41

Realtek Semiconductor 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, Realtek Semiconductor's adjusted Free Cash Flow per Share data for the three months ended in Jun. 2026 was:

Adj_FreeCashFlowPerShare= Free Cash Flow per Share /CPI of Jun. 2026 (Change)*Current CPI (Jun. 2026)
=0.99/333.9520*333.9520
=0.990

Current CPI (Jun. 2026) = 333.9520.
