Key Insights

• Using the 2 Stage Free Cash Flow to Equity, Proto Labs fair value estimate is US$42.19
• Current share price of US$34.17 suggests Proto Labs is potentially trading close to its fair value
• Analyst price target for PRLB is US$41.00 which is 2.8% below our fair value estimate

How far off is Proto Labs, Inc. (NYSE:PRLB) from its intrinsic value? Using the most recent financial data, we'll take a look at whether the stock is fairly priced by taking the expected future cash flows and discounting them to today's value. We will use the Discounted Cash Flow (DCF) model on this occasion. It may sound complicated, but actually it is quite simple!

We generally believe that a company's value is the present value of all of the cash it will generate in the future. However, a DCF is just one valuation metric among many, and it is not without flaws. For those who are keen learners of equity analysis, the Simply Wall St analysis model here may be something of interest to you.

Step By Step Through The Calculation

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. Seeing as no analyst estimates of free cash flow are available to us, we have extrapolate the previous free cash flow (FCF) from the company's last 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.

A DCF is all about the idea that a dollar in the future is less valuable than a dollar today, and so the sum of these future cash flows is then discounted to today's value:

10-year free cash flow (FCF) forecast

	2025	2026	2027	2028	2029	2030	2031	2032	2033	2034
Levered FCF ($, Millions)	US$47.1m	US$49.0m	US$50.7m	US$52.4m	US$53.9m	US$55.4m	US$56.9m	US$58.4m	US$59.8m	US$61.3m
Growth Rate Estimate Source	Est @ 4.82%	Est @ 4.09%	Est @ 3.58%	Est @ 3.22%	Est @ 2.97%	Est @ 2.79%	Est @ 2.67%	Est @ 2.58%	Est @ 2.52%	Est @ 2.48%
Present Value ($, Millions) Discounted @ 7.0%	US$44.0	US$42.8	US$41.4	US$40.0	US$38.4	US$36.9	US$35.4	US$34.0	US$32.6	US$31.2

("Est" = FCF growth rate estimated by Simply Wall St)
Present Value of 10-year Cash Flow (PVCF) = US$377m

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$61m× (1 + 2.4%) ÷ (7.0%– 2.4%) = US$1.4b

Present Value of Terminal Value (PVTV)= TV / (1 + r)¹⁰= US$1.4b÷ ( 1 + 7.0%)¹⁰= US$691m

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$1.1b. 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$34.2, the company appears about fair value at a 19% 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. You don't have to agree with these inputs, I recommend redoing the calculations yourself and playing with them. 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 Proto Labs 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 1.004. 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 Proto Labs

Next Steps:

Whilst important, the DCF calculation is only one of many factors that you need to assess for a company. The DCF model is not a perfect stock valuation tool. Preferably you'd apply different cases and assumptions and see how they would impact the company's valuation. For instance, if the terminal value growth rate is adjusted slightly, it can dramatically alter the overall result. For Proto Labs, we've compiled three essential elements you should further examine:
