Key Insights

• GMR Airports Infrastructure's estimated fair value is ₹48.96 based on 2 Stage Free Cash Flow to Equity
• With ₹43.10 share price, GMR Airports Infrastructure appears to be trading close to its estimated fair value
• GMR Airports Infrastructure's peers are currently trading at a premium of 90% on average

Today we will run through one way of estimating the intrinsic value of GMR Airports Infrastructure Limited (NSE:GMRINFRA) by taking the expected future cash flows and discounting them to today's value. We will use the Discounted Cash Flow (DCF) model on this occasion. Models like these may appear beyond the comprehension of a lay person, but they're fairly easy to follow.

Companies can be valued in a lot of ways, so we would point out that a DCF is not perfect for every situation. If you still have some burning questions about this type of valuation, take a look at the Simply Wall St analysis model.

Step By Step Through The Calculation

We're using the 2-stage growth model, which simply means we take in account two stages of company's growth. In the initial period the company may have a higher growth rate and the second stage is usually assumed to have a stable growth rate. To begin with, we have to get estimates of the next ten years of cash flows. Where possible we use analyst estimates, but when these aren't available we extrapolate the previous free cash flow (FCF) from the last estimate or reported value. We assume companies with shrinking free cash flow will slow their rate of shrinkage, and that companies with growing free cash flow will see their growth rate slow, over this period. We do this to reflect that growth tends to slow more in the early years than it does in later years.

Generally we assume that a dollar today is more valuable than a dollar in the future, so we need to discount the sum of these future cash flows to arrive at a present value estimate:

10-year free cash flow (FCF) estimate

("Est" = FCF growth rate estimated by Simply Wall St)
Present Value of 10-year Cash Flow (PVCF) = ₹157b

After calculating the present value of future cash flows in the initial 10-year period, we need to calculate the Terminal Value, which accounts for all future cash flows beyond the first stage. The Gordon Growth formula is used to calculate Terminal Value at a future annual growth rate equal to the 5-year average of the 10-year government bond yield of 6.8%. We discount the terminal cash flows to today's value at a cost of equity of 21%.

Terminal Value (TV)= FCF₂₀₃₂ × (1 + g) ÷ (r – g) = ₹131b× (1 + 6.8%) ÷ (21%– 6.8%) = ₹958b

Present Value of Terminal Value (PVTV)= TV / (1 + r)¹⁰= ₹958b÷ ( 1 + 21%)¹⁰= ₹138b

The total value, or equity value, is then the sum of the present value of the future cash flows, which in this case is ₹295b. The last step is to then divide the equity value by the number of shares outstanding. Relative to the current share price of ₹43.1, the company appears about fair value at a 12% discount to where the stock price trades currently. Remember though, that this is just an approximate valuation, and like any complex formula - garbage in, garbage out.

The Assumptions

Now 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 these inputs, I recommend redoing the calculations yourself and playing with them. The DCF also does not consider the possible cyclicality of an industry, or a company's future capital requirements, so it does not give a full picture of a company's potential performance. Given that we are looking at GMR Airports Infrastructure as potential shareholders, the cost of equity is used as the discount rate, rather than the cost of capital (or weighted average cost of capital, WACC) which accounts for debt. In this calculation we've used 21%, which is based on a levered beta of 1.497. Beta is a measure of a stock's volatility, compared to the market as a whole. We get our beta from the industry average beta of globally comparable companies, with an imposed limit between 0.8 and 2.0, which is a reasonable range for a stable business.

Next Steps:

Valuation is only one side of the coin in terms of building your investment thesis, and it shouldn't be the only metric you look at when researching a company. DCF models are not the be-all and end-all of investment valuation. Preferably you'd apply different cases and assumptions and see how they would impact the company's valuation. For example, changes in the company's cost of equity or the risk free rate can significantly impact the valuation.
