Key Insights

• Public Service Enterprise Group's estimated fair value is US$134 based on 2 Stage Free Cash Flow to Equity
• Public Service Enterprise Group is estimated to be 40% undervalued based on current share price of US$80.40
• The US$80.34 analyst price target for PEG is 40% less than our estimate of fair value

Today we'll do a simple run through of a valuation method used to estimate the attractiveness of Public Service Enterprise Group Incorporated (NYSE:PEG) as an investment opportunity by taking the forecast future cash flows of the company and discounting them back 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.

Crunching The Numbers

We are going to use a two-stage DCF model, which, as the name states, takes into account two stages of growth. The first stage is generally a higher growth period which levels off heading towards the terminal value, captured in the second 'steady growth' period. 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

("Est" = FCF growth rate estimated by Simply Wall St)
Present Value of 10-year Cash Flow (PVCF) = US$9.4b

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 2.5%. We discount the terminal cash flows to today's value at a cost of equity of 5.8%.

Terminal Value (TV)= FCF2034 × (1 + g) ÷ (r – g) = US$3.3b× (1 + 2.5%) ÷ (5.8%– 2.5%) = US$101b

Present Value of Terminal Value (PVTV)= TV / (1 + r)10= US$101b÷ ( 1 + 5.8%)10= US$58b

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$67b. 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$80.4, the company appears quite good value at a 40% 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

We would point out that the most important inputs to a discounted cash flow are the discount rate and of course the actual 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 Public Service Enterprise Group 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 5.8%, which is based on a levered beta of 0.800. 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 Public Service Enterprise Group

Looking Ahead:

Valuation is only one side of the coin in terms of building your investment thesis, and it ideally won't be the sole piece of analysis you scrutinize 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. What is the reason for the share price sitting below the intrinsic value? For Public Service Enterprise Group, we've put together three further factors you should look at:

1. Risks: Consider for instance, the ever-present spectre of investment risk. We've identified 3 warning signs with Public Service Enterprise Group (at least 1 which is significant) , and understanding them should be part of your investment process.
2. Management:Have insiders been ramping up their shares to take advantage of the market's sentiment for PEG's future outlook? Check out our management and board analysis with insights on CEO compensation and governance factors.
