Galatasaray Sportif Sinai Veticari Yatirimlar AS Peter Lynch Fair Value Calculation

Galatasaray Sportif Sinai Veticari Yatirimlar AS's Peter Lynch Fair Value for today is calculated as

Peter Lynch Fair Value=PEG Ratio*5-Year TTM EBITDA Growth Rate***EPS without NRI (TTM)
=1* N/A *-0.205
=N/A

Galatasaray Sportif Sinai Veticari Yatirimlar AS's EPS without NRI for the trailing twelve months (TTM) ended in Feb. 2026 adds up the quarterly data reported by the company within the most recent 12 months, which was ₺-0.21.


* For Operating Data section: All numbers are indicated by the unit behind each term and all currency related amount are in USD.
* For other sections: All numbers are in millions except for per share data, ratio, and percentage. All currency related amount are indicated in the company's associated stock exchange currency.

** Please be aware that the 5-Year TTM EBITDA Growth Rate is calculated based on TTM data over the last 5 years. For quarterly reported companies, the TTM data adds up the quarterly data reported by the company within the most recent 12 months. For companies that report semi-annually, annually, or do not have enough quarterly data, GuruFocus uses the annual data as the TTM data.

If 5-Year Earnings Growth Rate is greater than 25% a year, we use 25.

If 5-Year Earnings Growth Rate is smaller than 5% a year, we do not calculate Peter Lynch Fair Value.

Please note that we use the 5-year average growth rate of EBITDA per share as the growth rate for non-bank companies, as EBITDA growth is subject to less manipulations than net earnings per share. For banks, we use the 5-year average growth rate of Book Value per share as the growth rate. The reason is that EBITDA is not applicable to Banks and Book value is a relative important measurement for Banks. In the calculation, PEG=1 because Peter Lynch thinks that the fair P/E ratio of the growth stock is equal to its earnings growth rate.
