How far off is Port of Tauranga Limited (NZSE:POT) from its intrinsic value? Using the most recent financial data, we'll take a look at whether the stock is fairly priced by taking the forecast future cash flows of the company and discounting them back to today's value. We will take advantage of the Discounted Cash Flow (DCF) model for this purpose. It may sound complicated, but actually it is quite simple!
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.
Is Port of Tauranga fairly valued?
We use what is known as a 2-stage model, which simply means we have two different periods of growth rates for the company's cash flows. Generally the first stage is higher growth, and the second stage is a lower growth phase. In the first stage we need to estimate the cash flows to the business over the next ten years. 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.
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) forecast
Levered FCF (NZ$, Millions)
Growth Rate Estimate Source
Est @ 10.18%
Est @ 7.74%
Est @ 6.03%
Est @ 4.83%
Est @ 3.99%
Est @ 3.41%
Est @ 3%
Est @ 2.71%
Est @ 2.51%
Est @ 2.37%
Present Value (NZ$, Millions) Discounted @ 5.6%
("Est" = FCF growth rate estimated by Simply Wall St)
Present Value of 10-year Cash Flow (PVCF) = NZ$1.1b
The second stage is also known as Terminal Value, this is the business's cash flow after the first stage. 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 2.0%. We discount the terminal cash flows to today's value at a cost of equity of 5.6%.
Terminal Value (TV)= FCF2031 × (1 + g) ÷ (r – g) = NZ$173m× (1 + 2.0%) ÷ (5.6%– 2.0%) = NZ$5.0b
Present Value of Terminal Value (PVTV)= TV / (1 + r)10= NZ$5.0b÷ ( 1 + 5.6%)10= NZ$2.9b
The total value, or equity value, is then the sum of the present value of the future cash flows, which in this case is NZ$4.0b. In the final step we divide the equity value by the number of shares outstanding. Compared to the current share price of NZ$6.3, the company appears around fair value 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.
Now the most important inputs to a discounted cash flow are the discount rate, and of course, the actual cash flows. If you don't agree with these result, have a go at the calculation yourself and play with the 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 Port of Tauranga 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 5.6%, which is based on a levered beta of 0.835. 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.
Whilst important, the DCF calculation is only one of many factors that you need to assess for a company. DCF models are not the be-all and end-all of investment valuation. 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 Port of Tauranga, we've put together three further factors you should assess:
