Are Investors Undervaluing Spark New Zealand Limited (NZSE:SPK) By 41%?

Key Insights

• Spark New Zealand's estimated fair value is NZ$5.83 based on 2 Stage Free Cash Flow to Equity
• Spark New Zealand is estimated to be 41% undervalued based on current share price of NZ$3.46
• Our fair value estimate is 26% higher than Spark New Zealand's analyst price target of NZ$4.63

In this article we are going to estimate the intrinsic value of Spark New Zealand Limited (NZSE:SPK) 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. 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. Anyone interested in learning a bit more about intrinsic value should have a read of 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.

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) estimate

("Est" = FCF growth rate estimated by Simply Wall St)
Present Value of 10-year Cash Flow (PVCF) = NZ$3.1b

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 (2.8%) 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 6.1%.

Terminal Value (TV)= FCF₂₀₃₄ × (1 + g) ÷ (r – g) = NZ$436m× (1 + 2.8%) ÷ (6.1%– 2.8%) = NZ$14b

Present Value of Terminal Value (PVTV)= TV / (1 + r)¹⁰= NZ$14b÷ ( 1 + 6.1%)¹⁰= NZ$7.5b

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$11b. The last step is to then divide the equity value by the number of shares outstanding. Relative to the current share price of NZ$3.5, the company appears quite undervalued at a 41% discount to where the stock price trades currently. 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.

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. 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 Spark New Zealand 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 6.1%, 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 Spark New Zealand

Looking Ahead:

Although the valuation of a company is important, it is only one of many factors that you need to assess 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. 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. What is the reason for the share price sitting below the intrinsic value? For Spark New Zealand, there are three pertinent items you should further research:

1. Risks: You should be aware of the 3 warning signs for Spark New Zealand (1 is a bit concerning!) we've uncovered before considering an investment in the company.
2. Management:Have insiders been ramping up their shares to take advantage of the market's sentiment for SPK's future outlook? Check out our management and board analysis with insights on CEO compensation and governance factors.
