A Look At The Fair Value Of Mahanagar Gas Limited (NSE:MGL)

I am going to run you through how I calculated the intrinsic value of Mahanagar Gas Limited (NSE:MGL) by taking the foreast future cash flows of the company and discounting them back to today’s value. This is done using the Discounted Cash Flows (DCF) model. It may sound complicated, but actually it is quite simple! If you want to learn more about discounted cash flow, the basis for my calcs can be read in detail in the Simply Wall St analysis model. Please also note that this article was written in January 2019 so be sure check out the updated calculation by following the link below.

Step by step through the calculation

I use what is known as a 2-stage model, which simply means we have two different periods of varying growth rates for the company’s cash flows. Generally the first stage is higher growth, and the second stage is a more stable growth phase. To start off with we need to estimate the next five years of cash flows. For this I used the consensus of the analysts covering the stock, as you can see below. The sum of these cash flows is then discounted to today’s value.

5-year cash flow estimate

2019 2020 2021 2022 2023
Levered FCF (₹, Millions) ₹4.06k ₹4.78k ₹5.26k ₹5.89k ₹6.76k
Source Analyst x9 Analyst x11 Analyst x4 Analyst x3 Analyst x3
Present Value Discounted @ 13.51% ₹3.57k ₹3.71k ₹3.59k ₹3.55k ₹3.59k

Present Value of 5-year Cash Flow (PVCF)= ₹18b

We now need to calculate the Terminal Value, which accounts for all the future cash flows after the five years. The Gordon Growth formula is used to calculate Terminal Value at an annual growth rate equal to the 10-year government bond rate of 7.6%. We discount this to today’s value at a cost of equity of 13.5%.

Terminal Value (TV) = FCF2023 × (1 + g) ÷ (r – g) = ₹6.8b × (1 + 7.6%) ÷ (13.5% – 7.6%) = ₹122b

Present Value of Terminal Value (PVTV) = TV / (1 + r)5 = ₹122b ÷ ( 1 + 13.5%)5 = ₹65b

The total value is the sum of cash flows for the next five years and the discounted terminal value, which results in the Total Equity Value, which in this case is ₹83b. To get the intrinsic value per share, we divide this by the total number of shares outstanding, or the equivalent number if this is a depositary receipt or ADR. This results in an intrinsic value of ₹837.82. Relative to the current share price of ₹920.1, the stock is fair value, maybe slightly overvalued and not available at a discount at this time.

Important assumptions

I’d like to point out that the most important inputs to a discounted cash flow are the discount rate and of course the actual cash flows. You don’t have to agree with my inputs, I recommend redoing the calculations yourself and playing with them. Because we are looking at Mahanagar Gas as potential shareholders, the cost of equity is used as the discount rate, rather than the cost of capital (or weighed average cost of capital, WACC) which accounts for debt. In this calculation I’ve used 13.5%, which is based on a levered beta of 0.800. This is derived from the Bottom-Up Beta method based on comparable companies, with an imposed limit between 0.8 and 2.0, which is a reasonable range for a stable business.
