Estimating The Intrinsic Value Of Airo Lam Limited (NSE:AIROLAM)

Today we'll do a simple run through of a valuation method used to estimate the attractiveness of Airo Lam Limited (NSE:AIROLAM) as an investment opportunity 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. Believe it or not, it's not too difficult to follow, as you'll see from our example!

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 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.

Crunching the numbers

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 start off with, we need to estimate 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, 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)	₹42.3m	₹63.6m	₹87.2m	₹111.8m	₹136.0m	₹159.5m	₹182.1m	₹203.8m	₹225.0m	₹246.0m
Growth Rate Estimate Source	Est @ 68.81%	Est @ 50.22%	Est @ 37.21%	Est @ 28.1%	Est @ 21.72%	Est @ 17.26%	Est @ 14.13%	Est @ 11.94%	Est @ 10.41%	Est @ 9.34%
Present Value (₹, Millions) Discounted @ 19%	₹35.5	₹44.8	₹51.6	₹55.4	₹56.6	₹55.7	₹53.4	₹50.1	₹46.4	₹42.6

("Est" = FCF growth rate estimated by Simply Wall St)
Present Value of 10-year Cash Flow (PVCF) = ₹492m

We now need to calculate the Terminal Value, which accounts for all the future cash flows after this ten year period. 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 19%.

Terminal Value (TV)= FCF₂₀₃₁ × (1 + g) ÷ (r – g) = ₹246m× (1 + 6.8%) ÷ (19%– 6.8%) = ₹2.1b

Present Value of Terminal Value (PVTV)= TV / (1 + r)¹⁰= ₹2.1b÷ ( 1 + 19%)¹⁰= ₹369m

The total value, or equity value, is then the sum of the present value of the future cash flows, which in this case is ₹861m. The last step is to then divide the equity value by the number of shares outstanding. Relative to the current share price of ₹51.8, the company appears about fair value at a 9.8% 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

Now the most important inputs to a discounted cash flow are the discount rate, and of course, the actual cash flows. Part of investing is coming up with your own evaluation of a company's future performance, so try the calculation yourself and check your own 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 Airo Lam 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 19%, which is based on a levered beta of 1.799. 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 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. 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. For Airo Lam, we've compiled three further aspects you should further examine:
