How far off is Servotech Power Systems Limited (NSE:SERVOTECH) from its intrinsic value? Using the most recent financial data, we'll take a look at whether the stock is fairly priced by taking the forecast future cash flows of the company and discounting them back to today's value. We will use the Discounted Cash Flow (DCF) model on this occasion. Before you think you won't be able to understand it, just read on! It's actually much less complex than you'd imagine.

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. If you still have some burning questions about this type of valuation, take a look at the Simply Wall St analysis model.

Crunching the numbers

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. In the first stage we need to estimate the cash flows to the business over the next ten years. 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, so we discount the value of these future cash flows to their estimated value in today's dollars:

10-year free cash flow (FCF) estimate

2022 2023 2024 2025 2026 2027 2028 2029 2030 2031
Levered FCF (₹, Millions) ₹109.1m ₹138.8m ₹168.0m ₹196.3m ₹223.3m ₹249.3m ₹274.7m ₹299.9m ₹325.2m ₹350.9m
Growth Rate Estimate Source Est @ 36.04% Est @ 27.25% Est @ 21.1% Est @ 16.79% Est @ 13.77% Est @ 11.66% Est @ 10.19% Est @ 9.15% Est @ 8.43% Est @ 7.92%
Present Value (₹, Millions) Discounted @ 14% ₹95.4 ₹106 ₹113 ₹115 ₹115 ₹112 ₹108 ₹103 ₹98.0 ₹92.6

("Est" = FCF growth rate estimated by Simply Wall St)
Present Value of 10-year Cash Flow (PVCF) = ₹1.1b

We now need to calculate the Terminal Value, which accounts for all the future cash flows after this ten year period. 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 14%.

Terminal Value (TV)= FCF2031 × (1 + g) ÷ (r – g) = ₹351m× (1 + 6.7%) ÷ (14%– 6.7%) = ₹5.0b

Present Value of Terminal Value (PVTV)= TV / (1 + r)10= ₹5.0b÷ ( 1 + 14%)10= ₹1.3b

The total value is the sum of cash flows for the next ten years plus the discounted terminal value, which results in the Total Equity Value, which in this case is ₹2.4b. To get the intrinsic value per share, we divide this by the total number of shares outstanding. Relative to the current share price of ₹106, the company appears about fair value at a 18% 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

Now the most important inputs to a discounted cash flow are the discount rate, and of course, the actual 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 Servotech Power Systems 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 14%, which is based on a levered beta of 1.206. 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.

Looking Ahead:

Although the valuation of a company is important, it ideally won't be the sole piece of analysis you scrutinize 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 instance, if the terminal value growth rate is adjusted slightly, it can dramatically alter the overall result.
