How far off is Quest Diagnostics Incorporated (NYSE:DGX) from its intrinsic value? Using the most recent financial data, I am going to take a look at whether the stock is fairly priced by estimating the company’s future cash flows and discounting them to their present value. This is done using the discounted cash flows (DCF) model. Don’t get put off by the jargon, the math behind it is actually quite straightforward. Anyone interested in learning a bit more about intrinsic value should have a read of the Simply Wall St analysis model. If you are reading this and its not February 2019 then I highly recommend you check out the latest calculation for Quest Diagnostics by following the link below.
Crunching the numbers
I use what is known as a 2-stage model, which simply means we have two different periods of varying growth rates for the company’s cash flows. Generally the first stage is higher growth, and the second stage is a more stable growth phase. To begin with we have to get estimates of the next five years of cash flows. For this I used the consensus of the analysts covering the stock, as you can see below. The sum of these cash flows is then discounted to today’s value.
5-year cash flow forecast
|Levered FCF ($, Millions)||$865.32||$923.32||$978.00||$993.13||$1.01k|
|Source||Analyst x6||Analyst x4||Analyst x1||Est @ 1.55%||Est @ 1.55%|
|Present Value Discounted @ 9.7%||$788.80||$767.24||$740.81||$685.75||$634.78|
Present Value of 5-year Cash Flow (PVCF)= US$3.6b
After calculating the present value of future cash flows in the intial 5-year period we need to calculate the Terminal Value, which accounts for all the future cash flows beyond the first stage. The Gordon Growth formula is used to calculate Terminal Value at an annual growth rate equal to the 10-year government bond rate of 2.7%. We discount this to today’s value at a cost of equity of 9.7%.
Terminal Value (TV) = FCF2023 × (1 + g) ÷ (r – g) = US$1.0b × (1 + 2.7%) ÷ (9.7% – 2.7%) = US$15b
Present Value of Terminal Value (PVTV) = TV / (1 + r)5 = US$15b ÷ ( 1 + 9.7%)5 = US$9.4b
The total value is the sum of cash flows for the next five years and the discounted terminal value, which results in the Total Equity Value, which in this case is US$13b. The last step is to then divide the equity value by the number of shares outstanding. If the stock is an depositary receipt (represents a specified number of shares in a foreign corporation) then we use the equivalent number. This results in an intrinsic value of $95.33. Relative to the current share price of $89.09, the stock is about right, perhaps slightly undervalued at a 6.5% discount to what it is available for right now.
I’d like to 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 my inputs, I recommend redoing the calculations yourself and playing with them. Because we are looking at Quest Diagnostics as potential shareholders, the cost of equity is used as the discount rate, rather than the cost of capital (or weighed average cost of capital, WACC) which accounts for debt. In this calculation I’ve used 9.7%, which is based on a levered beta of 0.959. This is derived from the Bottom-Up Beta method based on comparable companies, with an imposed limit between 0.8 and 2.0, which is a reasonable range for a stable business.
