Estimating The Fair Value Of Energy Recovery, Inc. (NASDAQ:ERII)
Key Insights
- Using the 2 Stage Free Cash Flow to Equity, Energy Recovery fair value estimate is US$17.86
- Energy Recovery's US$14.31 share price indicates it is trading at similar levels as its fair value estimate
- The US$20.50 analyst price target for ERII is 15% more than our estimate of fair value
Today we'll do a simple run through of a valuation method used to estimate the attractiveness of Energy Recovery, Inc. (NASDAQ:ERII) as an investment opportunity by taking the expected future cash flows and discounting them to their present value. We will use the Discounted Cash Flow (DCF) model on this occasion. Before you think you won't be able to understand it, just read on! It's actually much less complex than you'd imagine.
Companies can be valued in a lot of ways, so we would point out that a DCF is not perfect for every situation. For those who are keen learners of equity analysis, the Simply Wall St analysis model here may be something of interest to you.

The Method
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.
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:
10-year free cash flow (FCF) forecast
2025 | 2026 | 2027 | 2028 | 2029 | 2030 | 2031 | 2032 | 2033 | 2034 | |
Levered FCF ($, Millions) | US$36.1m | US$40.6m | US$44.3m | US$47.5m | US$50.2m | US$52.6m | US$54.7m | US$56.7m | US$58.5m | US$60.2m |
Growth Rate Estimate Source | Analyst x2 | Est @ 12.22% | Est @ 9.27% | Est @ 7.20% | Est @ 5.75% | Est @ 4.74% | Est @ 4.03% | Est @ 3.54% | Est @ 3.19% | Est @ 2.95% |
Present Value ($, Millions) Discounted @ 7.0% | US$33.8 | US$35.4 | US$36.2 | US$36.3 | US$35.8 | US$35.1 | US$34.1 | US$33.0 | US$31.9 | US$30.7 |
("Est" = FCF growth rate estimated by Simply Wall St)
Present Value of 10-year Cash Flow (PVCF) = US$342m
The second stage is also known as Terminal Value, this is the business's cash flow after 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 2.4%. We discount the terminal cash flows to today's value at a cost of equity of 7.0%.
Terminal Value (TV)= FCF2034 × (1 + g) ÷ (r – g) = US$60m× (1 + 2.4%) ÷ (7.0%– 2.4%) = US$1.3b
Present Value of Terminal Value (PVTV)= TV / (1 + r)10= US$1.3b÷ ( 1 + 7.0%)10= US$682m
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 US$1.0b. To get the intrinsic value per share, we divide this by the total number of shares outstanding. Relative to the current share price of US$14.3, the company appears about fair value at a 20% 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
The calculation above is very dependent on two assumptions. The first is the discount rate and the other is the 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 Energy Recovery 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 7.0%, which is based on a levered beta of 1.001. 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.

Next Steps:
Although the valuation of a company is important, it shouldn't be the only metric you look at when researching a company. The DCF model is not a perfect stock valuation tool. Rather it should be seen as a guide to "what assumptions need to be true for this stock to be under/overvalued?" For example, changes in the company's cost of equity or the risk free rate can significantly impact the valuation. For Energy Recovery, we've compiled three pertinent items you should consider:
