A Look At The Intrinsic Value Of Bigbloc Construction Limited (NSE:BIGBLOC)

Today we'll do a simple run through of a valuation method used to estimate the attractiveness of Bigbloc Construction Limited (NSE:BIGBLOC) as an investment opportunity by taking the expected future cash flows and discounting them to today's value. Our analysis will employ the Discounted Cash Flow (DCF) model. It may sound complicated, but actually it is quite simple!

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. 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.

A DCF is all about the idea that a dollar in the future is less valuable than a dollar today, and so the sum of these future cash flows is then discounted to today's value:

	2022	2023	2024	2025	2026	2027	2028	2029	2030	2031
Levered FCF (₹, Millions)	₹88.0m	₹126.4m	₹167.4m	₹208.9m	₹249.3m	₹288.1m	₹325.4m	₹361.4m	₹396.7m	₹431.8m
Growth Rate Estimate Source	Est @ 59.29%	Est @ 43.53%	Est @ 32.49%	Est @ 24.77%	Est @ 19.36%	Est @ 15.57%	Est @ 12.92%	Est @ 11.07%	Est @ 9.77%	Est @ 8.86%

("Est" = FCF growth rate estimated by Simply Wall St)
Present Value of 10-year Cash Flow (PVCF) = ₹1.3b

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 (6.7%) 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 12%.

Terminal Value (TV)= FCF₂₀₃₁ × (1 + g) ÷ (r – g) = ₹432m× (1 + 6.7%) ÷ (12%– 6.7%) = ₹8.8b

Present Value of Terminal Value (PVTV)= TV / (1 + r)¹⁰= ₹8.8b÷ ( 1 + 12%)¹⁰= ₹2.8b

The total value, or equity value, is then the sum of the present value of the future cash flows, which in this case is ₹4.1b. In the final step we divide the equity value by the number of shares outstanding. Relative to the current share price of ₹54.3, the company appears about fair value at a 7.8% 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 Bigbloc Construction 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 12%, which is based on a levered beta of 0.840. 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.

Moving On:

Whilst important, the DCF calculation 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. Rather it should be seen as a guide to "what assumptions need to be true for this stock to be under/overvalued?" For instance, if the terminal value growth rate is adjusted slightly, it can dramatically alter the overall result.
