Estimating The Intrinsic Value Of Penumbra, Inc. (NYSE:PEN)

Key Insights

• Penumbra's estimated fair value is US$216 based on 2 Stage Free Cash Flow to Equity
• Current share price of US$236 suggests Penumbra is potentially trading close to its fair value
• Analyst price target for PEN is US$281, which is 30% above our fair value estimate

Today we will run through one way of estimating the intrinsic value of Penumbra, Inc. (NYSE:PEN) by projecting its future cash flows and then discounting them to today's value. We will use the Discounted Cash Flow (DCF) model on this occasion. There's really not all that much to it, even though it might appear quite complex.

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.

Is Penumbra Fairly Valued?

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.

A DCF is all about the idea that a dollar in the future is less valuable than a dollar today, 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

	2024	2025	2026	2027	2028	2029	2030	2031	2032	2033
Levered FCF ($, Millions)	US$105.3m	US$127.3m	US$160.3m	US$243.0m	US$309.0m	US$358.6m	US$401.4m	US$437.6m	US$468.3m	US$494.5m
Growth Rate Estimate Source	Analyst x5	Analyst x4	Analyst x3	Analyst x1	Analyst x1	Est @ 16.06%	Est @ 11.93%	Est @ 9.03%	Est @ 7.01%	Est @ 5.59%
Present Value ($, Millions) Discounted @ 6.5%	US$98.8	US$112	US$133	US$189	US$225	US$245	US$258	US$264	US$265	US$262

("Est" = FCF growth rate estimated by Simply Wall St)
Present Value of 10-year Cash Flow (PVCF) = US$2.1b

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 (2.3%) 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 6.5%.

Terminal Value (TV)= FCF₂₀₃₃ × (1 + g) ÷ (r – g) = US$495m× (1 + 2.3%) ÷ (6.5%– 2.3%) = US$12b

Present Value of Terminal Value (PVTV)= TV / (1 + r)¹⁰= US$12b÷ ( 1 + 6.5%)¹⁰= US$6.3b

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$8.4b. In the final step we divide the equity value by the number of shares outstanding. Compared to the current share price of US$236, the company appears around fair value at the time of writing. The assumptions in any calculation have a big impact on the valuation, so it is better to view this as a rough estimate, not precise down to the last cent.

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 Penumbra 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 6.5%, which is based on a levered beta of 0.924. 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 is only one of many factors that you need to assess for 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 instance, if the terminal value growth rate is adjusted slightly, it can dramatically alter the overall result. For Penumbra, we've put together three pertinent elements you should consider:
