Key Insights

• The projected fair value for PubMatic is US$23.10 based on 2 Stage Free Cash Flow to Equity
• PubMatic's US$21.18 share price indicates it is trading at similar levels as its fair value estimate
• The US$28.25 analyst price target for PUBM is 22% 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 PubMatic, Inc.

There's really not all that much to it, even though it might appear quite complex.

Remember though, that there are many ways to estimate a company's value, and a DCF is just one method. Anyone interested in learning a bit more about intrinsic value should have a read of the Simply Wall St analysis model.

Is PubMatic 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. In the first stage we need to estimate the cash flows to the business over the next ten years. 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, so we discount the value of these future cash flows to their estimated value in today's dollars:

10-year free cash flow (FCF) estimate

	2025	2026	2027	2028	2029	2030	2031	2032	2033	2034
Levered FCF ($, Millions)	US$48.8m	US$49.0m	US$49.4m	US$50.1m	US$51.0m	US$52.0m	US$53.0m	US$54.2m	US$55.4m	US$56.6m
Growth Rate Estimate Source	Est @ -0.48%	Est @ 0.38%	Est @ 0.98%	Est @ 1.40%	Est @ 1.69%	Est @ 1.90%	Est @ 2.04%	Est @ 2.14%	Est @ 2.22%	Est @ 2.26%
Present Value ($, Millions) Discounted @ 6.4%	US$45.9	US$43.3	US$41.1	US$39.2	US$37.4	US$35.9	US$34.4	US$33.0	US$31.7	US$30.5

("Est" = FCF growth rate estimated by Simply Wall St)
Present Value of 10-year Cash Flow (PVCF) = US$372m

After calculating the present value of future cash flows in the initial 10-year period, we need to calculate the Terminal Value, which accounts for all future cash flows beyond 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 6.4%.

Terminal Value (TV)= FCF₂₀₃₄ × (1 + g) ÷ (r – g) = US$57m× (1 + 2.4%) ÷ (6.4%– 2.4%) = US$1.4b

Present Value of Terminal Value (PVTV)= TV / (1 + r)¹⁰= US$1.4b÷ ( 1 + 6.4%)¹⁰= US$781m

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$1.2b. 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$21.2, the company appears about fair value at a 8.3% 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.

The Assumptions

Now the most important inputs to a discounted cash flow are the discount rate, and of course, the actual 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 PubMatic 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 6.4%, which is based on a levered beta of 0.869. 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 PubMatic

Looking Ahead:

Although the valuation of a company is important, 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. 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 PubMatic, we've put together three important elements you should assess:

1. Risks: As an example, we've found 2 warning signs for PubMatic that you need to consider before investing here.
