In this article we are going to estimate the intrinsic value of Smiths Group plc (LON:SMIN) by projecting its future cash flows and then discounting them to today's value. This will be done using the Discounted Cash Flow (DCF) model. Don't get put off by the jargon, the math behind it is actually quite straightforward.

Remember though, that there are many ways to estimate a company's value, and a DCF is just one method. 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.

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

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

 2022 2023 2024 2025 2026 2027 2028 2029 2030 2031 Levered FCF (£, Millions) UK£340.4m UK£354.4m UK£509.0m UK£532.0m UK£548.6m UK£562.1m UK£573.4m UK£583.0m UK£591.4m UK£599.1m Growth Rate Estimate Source Analyst x6 Analyst x5 Analyst x1 Analyst x1 Est @ 3.12% Est @ 2.46% Est @ 2% Est @ 1.68% Est @ 1.45% Est @ 1.29% Present Value (£, Millions) Discounted @ 6.4% UK£320 UK£313 UK£422 UK£415 UK£402 UK£387 UK£371 UK£354 UK£338 UK£321

("Est" = FCF growth rate estimated by Simply Wall St)
Present Value of 10-year Cash Flow (PVCF) = UK£3.6b

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 (0.9%) 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 6.4%.

Terminal Value (TV)= FCF2031 × (1 + g) ÷ (r – g) = UK£599m× (1 + 0.9%) ÷ (6.4%– 0.9%) = UK£11b

Present Value of Terminal Value (PVTV)= TV / (1 + r)10= UK£11b÷ ( 1 + 6.4%)10= UK£5.9b

The total value, or equity value, is then the sum of the present value of the future cash flows, which in this case is UK£9.5b. The last step is to then divide the equity value by the number of shares outstanding. Compared to the current share price of UK£16.1, the company appears quite good value at a 33% 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

We would point out that 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 Smiths Group 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 6.4%, which is based on a levered beta of 1.036. 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.

### Moving On:

Whilst important, the DCF calculation is only one of many factors that you need to assess for a company. The DCF model is not a perfect stock valuation tool. Instead the best use for a DCF model is to test certain assumptions and theories to see if they would lead to the company being undervalued or overvalued. For example, changes in the company's cost of equity or the risk free rate can significantly impact the valuation. Why is the intrinsic value higher than the current share price?
