In this article we are going to estimate the intrinsic value of Sumco Corporation (TSE:3436) by taking the forecast future cash flows of the company and discounting them back to today's value. Our analysis will employ the Discounted Cash Flow (DCF) model. There's really not all that much to it, even though it might appear quite complex.
Remember though, that there are many ways to estimate a company's value, and a DCF is just one method. If you still have some burning questions about this type of valuation, take a look at the Simply Wall St analysis model.
The Calculation
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 begin with, we have to get estimates of 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, 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
| 2025 | 2026 | 2027 | 2028 | 2029 | 2030 | 2031 | 2032 | 2033 | 2034 | |
| Levered FCF (¥, Millions) | JP¥15.3b | JP¥65.4b | JP¥86.2b | JP¥60.7b | JP¥39.3b | JP¥34.8b | JP¥32.1b | JP¥30.4b | JP¥29.3b | JP¥28.5b |
| Growth Rate Estimate Source | Analyst x5 | Analyst x5 | Analyst x5 | Analyst x3 | Analyst x1 | Est @ -11.42% | Est @ -7.86% | Est @ -5.37% | Est @ -3.62% | Est @ -2.40% |
| Present Value (¥, Millions) Discounted @ 11% | JP¥13.8k | JP¥53.1k | JP¥63.1k | JP¥40.0k | JP¥23.3k | JP¥18.6k | JP¥15.5k | JP¥13.2k | JP¥11.4k | JP¥10.1k |
("Est" = FCF growth rate estimated by Simply Wall St)
Present Value of 10-year Cash Flow (PVCF) = JP¥262b
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 0.4%. We discount the terminal cash flows to today's value at a cost of equity of 11%.
Terminal Value (TV)= FCF2034 × (1 + g) ÷ (r – g) = JP¥29b× (1 + 0.4%) ÷ (11%– 0.4%) = JP¥272b
Present Value of Terminal Value (PVTV)= TV / (1 + r)10= JP¥272b÷ ( 1 + 11%)10= JP¥96b
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¥358b. In the final step we divide the equity value by the number of shares outstanding. Compared to the current share price of JP¥983, the company appears about fair value at a 4.0% 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 Sumco 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 11%, which is based on a levered beta of 2.000. 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:
Whilst important, the DCF calculation ideally won't be the sole piece of analysis you scrutinize for a company. The DCF model is not a perfect stock valuation tool. Preferably you'd apply different cases and assumptions and see how they would impact the company's valuation. For example, changes in the company's cost of equity or the risk free rate can significantly impact the valuation. For Sumco, we've compiled three essential elements you should look at:
- Risks: We feel that you should assess the 4 warning signs for Sumco (2 are concerning!) we've flagged before making an investment in the company.
