Nippon Telegraph and Telephone Corporation's (TSE:9432) Intrinsic Value Is Potentially 78% Above Its Share Price

Key Insights

• The projected fair value for Nippon Telegraph and Telephone is JP¥263 based on 2 Stage Free Cash Flow to Equity
• Current share price of JP¥148 suggests Nippon Telegraph and Telephone is potentially 44% undervalued
• Our fair value estimate is 49% higher than Nippon Telegraph and Telephone's analyst price target of JP¥177

In this article we are going to estimate the intrinsic value of Nippon Telegraph and Telephone Corporation (TSE:9432) 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. It may sound complicated, but actually it is quite simple!

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 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.

Is Nippon Telegraph and Telephone Fairly Valued?

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. To start off with, we need to estimate the next ten years of cash flows. 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.

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:

10-year free cash flow (FCF) forecast

("Est" = FCF growth rate estimated by Simply Wall St)
Present Value of 10-year Cash Flow (PVCF) = JP¥6.3t

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 (0.3%) 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 4.2%.

Terminal Value (TV)= FCF₂₀₃₄ × (1 + g) ÷ (r – g) = JP¥949b× (1 + 0.3%) ÷ (4.2%– 0.3%) = JP¥24t

Present Value of Terminal Value (PVTV)= TV / (1 + r)¹⁰= JP¥24t÷ ( 1 + 4.2%)¹⁰= JP¥16t

The total value, or equity value, is then the sum of the present value of the future cash flows, which in this case is JP¥22t. In the final step we divide the equity value by the number of shares outstanding. Compared to the current share price of JP¥148, the company appears quite undervalued at a 44% discount to where the stock price trades currently. 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 Nippon Telegraph and Telephone 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 4.2%, which is based on a levered beta of 0.800. 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.

SWOT Analysis for Nippon Telegraph and Telephone

Moving On:

Although the valuation of a company is important, it ideally won't be the sole piece of analysis you scrutinize for a company. The DCF model is not a perfect stock valuation tool. Rather it should be seen as a guide to "what assumptions need to be true for this stock to be under/overvalued?" If a company grows at a different rate, or if its cost of equity or risk free rate changes sharply, the output can look very different. Can we work out why the company is trading at a discount to intrinsic value? For Nippon Telegraph and Telephone, we've compiled three important items you should further research:
