Are Tech Mahindra Limited (NSE:TECHM) Investors Paying Above The Intrinsic Value?

Does the July share price for Tech Mahindra Limited (NSE:TECHM) reflect what it's really worth? Today, we will estimate the stock's intrinsic value by estimating the company's future cash flows and discounting them to their present value. One way to achieve this is by employing the Discounted Cash Flow (DCF) model. Don't get put off by the jargon, the math behind it is actually quite straightforward.

Companies can be valued in a lot of ways, so we would point out that a DCF is not perfect for every situation. If you still have some burning questions about this type of valuation, take a look at the Simply Wall St analysis model.

Step by step through the calculation

We're using the 2-stage growth model, which simply means we take in account two stages of company's growth. In the initial period the company may have a higher growth rate and the second stage is usually assumed to have a stable growth rate. In the first stage we need to estimate the cash flows to the business over the next ten years. 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.

Generally we assume that a dollar today is more valuable than a dollar in the future, so we need to discount the sum of these future cash flows to arrive at a present value estimate:

10-year free cash flow (FCF) estimate

	2023	2024	2025	2026	2027	2028	2029	2030	2031	2032
Levered FCF (₹, Millions)	₹54.9b	₹63.4b	₹66.5b	₹64.1b	₹63.8b	₹65.0b	₹67.1b	₹70.0b	₹73.5b	₹77.6b
Growth Rate Estimate Source	Analyst x22	Analyst x22	Analyst x8	Analyst x1	Est @ -0.37%	Est @ 1.77%	Est @ 3.26%	Est @ 4.31%	Est @ 5.04%	Est @ 5.55%
Present Value (₹, Millions) Discounted @ 13%	₹48.5k	₹49.5k	₹45.8k	₹39.0k	₹34.3k	₹30.9k	₹28.2k	₹25.9k	₹24.1k	₹22.4k

("Est" = FCF growth rate estimated by Simply Wall St)
Present Value of 10-year Cash Flow (PVCF) = ₹349b

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 13%.

Terminal Value (TV)= FCF₂₀₃₂ × (1 + g) ÷ (r – g) = ₹78b× (1 + 6.8%) ÷ (13%– 6.8%) = ₹1.3t

Present Value of Terminal Value (PVTV)= TV / (1 + r)¹⁰= ₹1.3t÷ ( 1 + 13%)¹⁰= ₹371b

The total value, or equity value, is then the sum of the present value of the future cash flows, which in this case is ₹720b. In the final step we divide the equity value by the number of shares outstanding. Compared to the current share price of ₹1.0k, the company appears slightly overvalued at the time of writing. Valuations are imprecise instruments though, rather like a telescope - move a few degrees and end up in a different galaxy. Do keep this in mind.

The assumptions

The calculation above is very dependent on two assumptions. The first is the discount rate and the other is the 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 Tech Mahindra 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 13%, which is based on a levered beta of 1.005. 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:

Although the valuation of a company is important, it ideally won't be the sole piece of analysis you scrutinize for a company. It's not possible to obtain a foolproof valuation with a DCF model. 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. Can we work out why the company is trading at a premium to intrinsic value?
