An Intrinsic Calculation For Interroll Holding AG (VTX:INRN) Suggests It's 23% Undervalued

Key Insights

• The projected fair value for Interroll Holding is CHF3,105 based on 2 Stage Free Cash Flow to Equity
• Interroll Holding's CHF2,405 share price signals that it might be 23% undervalued
• The CHF2,581 analyst price target for INRN is 17% less than our estimate of fair value

Today we will run through one way of estimating the intrinsic value of Interroll Holding AG (VTX:INRN) by projecting its future cash flows and then discounting them to today's value. One way to achieve this is by employing the Discounted Cash Flow (DCF) model. There's really not all that much to it, even though it might appear quite complex.

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. For those who are keen learners of equity analysis, the Simply Wall St analysis model here may be something of interest to you.

Is Interroll Holding Fairly Valued?

We use what is known as a 2-stage model, which simply means we have two different periods of growth rates for the company's cash flows. Generally the first stage is higher growth, and the second stage is a lower growth phase. To start off with, we need to estimate 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 (CHF, Millions)	CHF67.7m	CHF77.6m	CHF83.6m	CHF92.6m	CHF98.7m	CHF103.4m	CHF106.9m	CHF109.5m	CHF111.5m	CHF113.0m
Growth Rate Estimate Source	Analyst x3	Analyst x3	Analyst x1	Analyst x1	Est @ 6.64%	Est @ 4.72%	Est @ 3.38%	Est @ 2.44%	Est @ 1.78%	Est @ 1.32%
Present Value (CHF, Millions) Discounted @ 4.4%	CHF64.9	CHF71.2	CHF73.6	CHF78.1	CHF79.8	CHF80.1	CHF79.4	CHF77.9	CHF76.0	CHF73.8

("Est" = FCF growth rate estimated by Simply Wall St)
Present Value of 10-year Cash Flow (PVCF) = CHF755m

We now need to calculate the Terminal Value, which accounts for all the future cash flows after this ten year period. For a number of reasons a very conservative growth rate is used that cannot exceed that of a country's GDP growth. In this case we have used the 5-year average of the 10-year government bond yield (0.3%) to estimate future growth. In the same way as with the 10-year 'growth' period, we discount future cash flows to today's value, using a cost of equity of 4.4%.

Terminal Value (TV)= FCF₂₀₃₄ × (1 + g) ÷ (r – g) = CHF113m× (1 + 0.3%) ÷ (4.4%– 0.3%) = CHF2.8b

Present Value of Terminal Value (PVTV)= TV / (1 + r)¹⁰= CHF2.8b÷ ( 1 + 4.4%)¹⁰= CHF1.8b

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 CHF2.6b. To get the intrinsic value per share, we divide this by the total number of shares outstanding. Relative to the current share price of CHF2.4k, the company appears a touch undervalued at a 23% 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

The calculation above is very dependent on two assumptions. The first is the discount rate and the other is the cash flows. Part of investing is coming up with your own evaluation of a company's future performance, so try the calculation yourself and check your own 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 Interroll Holding 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 4.4%, which is based on a levered beta of 0.995. 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 Interroll Holding

Moving On:

Valuation is only one side of the coin in terms of building your investment thesis, and it is only one of many factors that you need to assess for a company. It's not possible to obtain a foolproof valuation with a DCF model. Preferably you'd apply different cases and assumptions and see how they would impact the company's valuation. For example, changes in the company's cost of equity or the risk free rate can significantly impact the valuation. Why is the intrinsic value higher than the current share price?
