In this article we are going to estimate the intrinsic value of BOE Varitronix Limited (HKG:710) by projecting its future cash flows and then discounting them to today's value. We will take advantage of the Discounted Cash Flow (DCF) model for this purpose. Believe it or not, it's not too difficult to follow, as you'll see from our example!

We would caution that there are many ways of valuing a company and, like the DCF, each technique has advantages and disadvantages in certain scenarios. If you still have some burning questions about this type of valuation, take a look at the Simply Wall St analysis model.

### The model

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. 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, and so the sum of these future cash flows is then discounted to today's value:

#### 10-year free cash flow (FCF) forecast

 2021 2022 2023 2024 2025 2026 2027 2028 2029 2030 Levered FCF (HK\$, Millions) HK\$109.4m HK\$122.4m HK\$133.2m HK\$142.1m HK\$149.4m HK\$155.6m HK\$160.8m HK\$165.4m HK\$169.5m HK\$173.3m Growth Rate Estimate Source Est @ 16.28% Est @ 11.89% Est @ 8.81% Est @ 6.66% Est @ 5.16% Est @ 4.1% Est @ 3.36% Est @ 2.85% Est @ 2.48% Est @ 2.23% Present Value (HK\$, Millions) Discounted @ 9.7% HK\$99.8 HK\$102 HK\$101 HK\$98.2 HK\$94.2 HK\$89.4 HK\$84.3 HK\$79.0 HK\$73.8 HK\$68.8

("Est" = FCF growth rate estimated by Simply Wall St)
Present Value of 10-year Cash Flow (PVCF) = HK\$890m

The second stage is also known as Terminal Value, this is the business's cash flow after the first stage. 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 (1.6%) 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 9.7%.

Terminal Value (TV)= FCF2030 × (1 + g) ÷ (r – g) = HK\$173m× (1 + 1.6%) ÷ (9.7%– 1.6%) = HK\$2.2b

Present Value of Terminal Value (PVTV)= TV / (1 + r)10= HK\$2.2b÷ ( 1 + 9.7%)10= HK\$871m

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 HK\$1.8b. To get the intrinsic value per share, we divide this by the total number of shares outstanding. Compared to the current share price of HK\$2.2, the company appears about fair value at a 7.7% 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

The calculation above is very dependent on two assumptions. The first is the discount rate and the other is the 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 BOE Varitronix 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 9.7%, which is based on a levered beta of 1.128. 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:

Valuation is only one side of the coin in terms of building your investment thesis, and it shouldn't be the only metric you look at when researching 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 BOE Varitronix, we've put together three important aspects you should look at:

1. Risks: For example, we've discovered 2 warning signs for BOE Varitronix (1 doesn't sit too well with us!) that you should be aware of before investing here.
