Does the October share price for Oil and Natural Gas Corporation Limited (NSE:ONGC) reflect what it’s really worth? Today, we will estimate the stock’s intrinsic value by taking the expected future cash flows and discounting them to today’s value. Our analysis will employ the Discounted Cash Flow (DCF) model. Models like these may appear beyond the comprehension of a lay person, but they’re fairly easy to follow.
We would caution that there are many ways of valuing a company and, like the DCF, each technique has advantages and disadvantages in certain scenarios. If you want to learn more about discounted cash flow, the rationale behind this calculation can be read in detail in the Simply Wall St analysis model.

The Model
We use what is known as a 2-stage model, which simply means we have two different periods of growth rates for the company’s cash flows. Generally the first stage is higher growth, and the second stage is a lower growth phase. 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.
A DCF is all about the idea that a dollar in the future is less valuable than a dollar today, so we need to discount the sum of these future cash flows to arrive at a present value estimate:

Present Value (₹, Millions) Discounted @ 18% | ₹260.9k | ₹249.6k | ₹232.0k | ₹213.6k | ₹195.5k | ₹178.1k | ₹161.8k | ₹146.6k | ₹132.7k | ₹119.9k |
(“Est” = FCF growth rate estimated by Simply Wall St)
Present Value of 10-year Cash Flow (PVCF) = ₹1.9t
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. For a number of reasons a very conservative growth rate is used that cannot exceed that of a country’s GDP growth. In this case we have used the 5-year average of the 10-year government bond yield (6.8%) to estimate future growth. In the same way as with the 10-year ‘growth’ period, we discount future cash flows to today’s value, using a cost of equity of 18%.
Terminal Value (TV)= FCF2032 × (1 + g) ÷ (r – g) = ₹651b× (1 + 6.8%) ÷ (18%– 6.8%) = ₹6.0t
Present Value of Terminal Value (PVTV)= TV / (1 + r)10= ₹6.0t÷ ( 1 + 18%)10= ₹1.1t
The total value, or equity value, is then the sum of the present value of the future cash flows, which in this case is ₹3.0t. In the final step we divide the equity value by the number of shares outstanding. Compared to the current share price of ₹134, the company appears quite undervalued at a 44% 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.
Important Assumptions
The calculation above is very dependent on two assumptions. The first is the discount rate and the other is the cash flows. If you don’t agree with these result, have a go at the calculation yourself and play with the assumptions. 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 Oil and Natural Gas 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 18%, which is based on a levered beta of 1.646. 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:
Whilst important, the DCF calculation ideally won’t be the sole piece of analysis you scrutinize for a company. The DCF model is not a perfect stock valuation tool. Preferably you’d apply different cases and assumptions and see how they would impact the company’s valuation. For instance, if the terminal value growth rate is adjusted slightly, it can dramatically alter the overall result. Why is the intrinsic value higher than the current share price?
