# Ardelyx, Inc. (NASDAQ:ARDX) Is Trading At A 28.78% Discount

In this article I am going to calculate the intrinsic value of Ardelyx, Inc. (NASDAQ:ARDX) by taking the expected future cash flows and discounting them to todayâ€™s value. I will use the discounted cash flows (DCF) model. It may sound complicated, but actually it is quite simple! If you want to learn more about discounted cash flow, the basis for my calcs can be read in detail in the Simply Wall St analysis model. If you are reading this and its not January 2019 then I highly recommend you check out the latest calculation for Ardelyx by following the link below.

### Step by step through the calculation

Iâ€™m using the 2-stage growth model, which simply means we take in account two stages of companyâ€™s growth. In the initial period the company may have a higher growth rate and the second stage is usually assumed to have perpetual stable growth rate. 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. I then discount this to its value today and sum up the total to get the present value of these cash flows.

#### 5-year cash flow estimate

 2019 2020 2021 2022 2023 Levered FCF (\$, Millions) \$-89.90 \$-91.40 \$-21.20 \$31.30 \$77.30 Source Analyst x1 Analyst x1 Analyst x1 Analyst x1 Analyst x1 Present Value Discounted @ 15.42% \$-77.89 \$-68.61 \$-13.79 \$17.64 \$37.74

Present Value of 5-year Cash Flow (PVCF)= -US\$104.9m

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. For a number of reasons a very conservative growth rate is used that cannot exceed that of the GDP. In this case I have used the 10-year government bond rate (2.7%). In the same way as with the 5-year â€˜growthâ€™ period, we discount this to todayâ€™s value at a cost of equity of 15.4%.

Terminal Value (TV) = FCF2023 Ã— (1 + g) Ã· (r â€“ g) = US\$77m Ã— (1 + 2.7%) Ã· (15.4% â€“ 2.7%) = US\$626m

Present Value of Terminal Value (PVTV) = TV / (1 + r)5 = US\$626m Ã· ( 1 + 15.4%)5 = US\$306m

The total value, or equity value, is then the sum of the present value of the cash flows, which in this case is US\$201m. To get the intrinsic value per share, we divide this by the total number of shares outstanding, or the equivalent number if this is a depositary receipt or ADR. This results in an intrinsic value of \$3.23. Compared to the current share price of \$2.3, the stock is about right, perhaps slightly undervalued at a 29% discount to what it is available for right now.

### The assumptions

The calculation above is very dependent on two assumptions. The first is the discount rate and the other is the cash flows. You donâ€™t have to agree with my inputs, I recommend redoing the calculations yourself and playing with them. Because we are looking at Ardelyx 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 Iâ€™ve used 15.4%, which is based on a levered beta of 1.745. 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.

### Next Steps:

Whilst important, DCF calculation shouldnâ€™t be the only metric you look at when researching a company. What is the reason for the share price to differ from the intrinsic value? For ARDX, Iâ€™ve compiled three key factors you should look at:
