Key Insights

  • AZEK's estimated fair value is US$57.34 based on 2 Stage Free Cash Flow to Equity
  • AZEK's US$29.20 share price signals that it might be 49% undervalued
  • Analyst price target for AZEK is US$37.89 which is 34% below our fair value estimate

Today we'll do a simple run through of a valuation method used to estimate the attractiveness of The AZEK Company Inc. (NYSE:AZEK) as an investment opportunity 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. For those who are keen learners of equity analysis, the Simply Wall St analysis model here may be something of interest to you.

What's The Estimated Valuation?

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 start off with, we need to estimate 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 discount the value of these future cash flows to their estimated value in today's dollars:

Present Value of 10-year Cash Flow (PVCF) = US$3.0b

After calculating the present value of future cash flows in the initial 10-year period, we need to calculate the Terminal Value, which accounts for all future cash flows beyond 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 2.2%. We discount the terminal cash flows to today's value at a cost of equity of 8.0%.

Terminal Value (TV)= FCF2033 × (1 + g) ÷ (r – g) = US$690m× (1 + 2.2%) ÷ (8.0%– 2.2%) = US$12b

Present Value of Terminal Value (PVTV)= TV / (1 + r)10= US$12b÷ ( 1 + 8.0%)10= US$5.5b

The total value, or equity value, is then the sum of the present value of the future cash flows, which in this case is US$8.6b. The last step is to then divide the equity value by the number of shares outstanding. Compared to the current share price of US$29.2, the company appears quite good value at a 49% discount to where the stock price trades currently. Remember though, that this is just an approximate valuation, and like any complex formula - garbage in, garbage out.

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 AZEK 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 8.0%, which is based on a levered beta of 1.177. 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 AZEK

Strength
  • Debt is well covered by cash flow.
Weakness
  • Earnings declined over the past year.
  • Interest payments on debt are not well covered.
Opportunity
  • Annual earnings are forecast to grow faster than the American market.
  • Trading below our estimate of fair value by more than 20%.
Threat
  • Revenue is forecast to grow slower than 20% per year.

Looking Ahead:

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. DCF models are not the be-all and end-all of investment valuation. 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 instance, if the terminal value growth rate is adjusted slightly, it can dramatically alter the overall result. Why is the intrinsic value higher than the current share price?
