Estimating The Fair Value Of Gandhi Special Tubes Limited (NSE:GANDHITUBE)

Today we'll do a simple run through of a valuation method used to estimate the attractiveness of Gandhi Special Tubes Limited (NSE:GANDHITUBE) as an investment opportunity by taking the forecast future cash flows of the company and discounting them back to today's value. This will be done using the Discounted Cash Flow (DCF) model. It may sound complicated, but actually it is quite simple!

We generally believe that a company's value is the present value of all of the cash it will generate in the future. However, a DCF is just one valuation metric among many, and it is not without flaws. For those who are keen learners of equity analysis, the Simply Wall St analysis model here may be something of interest to you.

Step by step through the calculation

We are going to use a two-stage DCF model, which, as the name states, takes into account two stages of growth. The first stage is generally a higher growth period which levels off heading towards the terminal value, captured in the second 'steady growth' period. To begin with, we have to get estimates of the next ten years of cash flows. Seeing as no analyst estimates of free cash flow are available to us, we have extrapolate the previous free cash flow (FCF) from the company's last 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, and so the sum of these future cash flows is then discounted to today's value:

	2021	2022	2023	2024	2025	2026	2027	2028	2029	2030
Levered FCF (₹, Millions)	₹193.1m	₹212.5m	₹232.0m	₹252.0m	₹272.6m	₹294.0m	₹316.6m	₹340.4m	₹365.7m	₹392.6m
Growth Rate Estimate Source	Est @ 11.27%	Est @ 10.05%	Est @ 9.19%	Est @ 8.59%	Est @ 8.17%	Est @ 7.88%	Est @ 7.67%	Est @ 7.53%	Est @ 7.43%	Est @ 7.35%
Present Value (₹, Millions) Discounted @ 17%	₹166	₹157	₹147	₹137	₹127	₹118	₹109	₹100	₹92.5	₹85.2

("Est" = FCF growth rate estimated by Simply Wall St)
Present Value of 10-year Cash Flow (PVCF) = ₹1.2b

The second stage is also known as Terminal Value, this is the business's cash flow after 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 (7.2%) 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 17%.

Terminal Value (TV)= FCF₂₀₃₀ × (1 + g) ÷ (r – g) = ₹393m× (1 + 7.2%) ÷ (17%– 7.2%) = ₹4.5b

Present Value of Terminal Value (PVTV)= TV / (1 + r)¹⁰= ₹4.5b÷ ( 1 + 17%)¹⁰= ₹981m

The total value, or equity value, is then the sum of the present value of the future cash flows, which in this case is ₹2.2b. The last step is to then divide the equity value by the number of shares outstanding. Relative to the current share price of ₹200, the company appears around fair value at the time of writing. The assumptions in any calculation have a big impact on the valuation, so it is better to view this as a rough estimate, not precise down to the last cent.

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 Gandhi Special Tubes 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 17%, which is based on a levered beta of 0.981. 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 is only one of many factors that you need to assess for a company. DCF models are not the be-all and end-all of investment valuation. Instead the best use for a DCF model is to test certain assumptions and theories to see if they would lead to the company being undervalued or overvalued. For example, changes in the company's cost of equity or the risk free rate can significantly impact the valuation. For Gandhi Special Tubes, we've compiled three important items you should explore:
