Calculating The Fair Value Of IDEX Corporation (NYSE:IEX)

Key Insights

• IDEX's estimated fair value is US$232 based on 2 Stage Free Cash Flow to Equity

• With US$206 share price, IDEX appears to be trading close to its estimated fair value

• The US$232 analyst price target for IEXis comparable to our estimate of fair value.

Today we'll do a simple run through of a valuation method used to estimate the attractiveness of IDEX Corporation (NYSE:IEX) as an investment opportunity by estimating the company's future cash flows and discounting them to their present value. We will take advantage of the Discounted Cash Flow (DCF) model for this purpose. Don't get put off by the jargon, the math behind it is actually quite straightforward.

We would caution that there are many ways of valuing a company and, like the DCF, each technique has advantages and disadvantages in certain scenarios. Anyone interested in learning a bit more about intrinsic value should have a read of the Simply Wall St analysis model.

The Model

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. In the first stage we need to estimate the cash flows to the business over the next ten years. 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 need to discount the sum of these future cash flows to arrive at a present value estimate:

10-year free cash flow (FCF) estimate

	2023	2024	2025	2026	2027	2028	2029	2030	2031	2032
Levered FCF ($, Millions)	US$662.7m	US$712.4m	US$773.8m	US$859.0m	US$1.06b	US$1.16b	US$1.24b	US$1.32b	US$1.38b	US$1.43b
Growth Rate Estimate Source	Analyst x8	Analyst x9	Analyst x4	Analyst x3	Analyst x1	Est @ 9.79%	Est @ 7.48%	Est @ 5.85%	Est @ 4.72%	Est @ 3.92%
Present Value ($, Millions) Discounted @ 8.2%	US$612	US$609	US$611	US$627	US$712	US$722	US$717	US$702	US$679	US$652

("Est" = FCF growth rate estimated by Simply Wall St)
Present Value of 10-year Cash Flow (PVCF) = US$6.6b

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 2.1%. We discount the terminal cash flows to today's value at a cost of equity of 8.2%.

Terminal Value (TV)= FCF₂₀₃₂ × (1 + g) ÷ (r – g) = US$1.4b× (1 + 2.1%) ÷ (8.2%– 2.1%) = US$24b

Present Value of Terminal Value (PVTV)= TV / (1 + r)¹⁰= US$24b÷ ( 1 + 8.2%)¹⁰= US$11b

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$18b. To get the intrinsic value per share, we divide this by the total number of shares outstanding. Compared to the current share price of US$206, the company appears about fair value at a 11% 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 IDEX 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 8.2%, which is based on a levered beta of 1.031. 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 IDEX

• Debt is not viewed as a risk.

• Dividends are covered by earnings and cash flows.

Weakness

• Dividend is low compared to the top 25% of dividend payers in the Machinery market.

Opportunity

• Annual revenue is forecast to grow faster than the American market.

• Current share price is below our estimate of fair value.

Threat

• Annual earnings are forecast to grow slower than the American market.

Looking Ahead:

Whilst important, the DCF calculation ideally won't be the sole piece of analysis you scrutinize for a company. DCF models are not the be-all and end-all of investment valuation. Rather it should be seen as a guide to "what assumptions need to be true for this stock to be under/overvalued?" 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. For IDEX, we've compiled three relevant aspects you should assess:
