Is Integral Diagnostics Limited (ASX:IDX) Trading At A 43% Discount?

·6 min read

Today we'll do a simple run through of a valuation method used to estimate the attractiveness of Integral Diagnostics Limited (ASX:IDX) as an investment opportunity by estimating the company's future cash flows and discounting them to their present 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!

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.

Crunching The Numbers

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 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.

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:

("Est" = FCF growth rate estimated by Simply Wall St)
Present Value of 10-year Cash Flow (PVCF) = AU$346m

We now need to calculate the Terminal Value, which accounts for all the future cash flows after this ten year period. 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 1.8%. We discount the terminal cash flows to today's value at a cost of equity of 5.9%.

Terminal Value (TV)= FCF2032 × (1 + g) ÷ (r – g) = AU$52m× (1 + 1.8%) ÷ (5.9%– 1.8%) = AU$1.3b

Present Value of Terminal Value (PVTV)= TV / (1 + r)10= AU$1.3b÷ ( 1 + 5.9%)10= AU$722m

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 AU$1.1b. To get the intrinsic value per share, we divide this by the total number of shares outstanding. Compared to the current share price of AU$2.6, the company appears quite undervalued at a 43% 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.

Important 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. 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 Integral Diagnostics 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 5.9%, which is based on a levered beta of 0.966. 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.

Looking Ahead:

Whilst important, the DCF calculation 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. 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. Why is the intrinsic value higher than the current share price? For Integral Diagnostics, we've compiled three essential aspects you should assess:

  1. Risks: Consider for instance, the ever-present spectre of investment risk. We've identified 2 warning signs with Integral Diagnostics , and understanding these should be part of your investment process.

  2. Management:Have insiders been ramping up their shares to take advantage of the market's sentiment for IDX's future outlook? Check out our management and board analysis with insights on CEO compensation and governance factors.
