A Look At The Intrinsic Value Of AGL Energy Limited (ASX:AGL)

Key Insights

• AGL Energy's estimated fair value is AU$10.38 based on 2 Stage Free Cash Flow to Equity
• With AU$10.42 share price, AGL Energy appears to be trading close to its estimated fair value
• Our fair value estimate is 9.8% lower than AGL Energy's analyst price target of AU$11.50

Today we will run through one way of estimating the intrinsic value of AGL Energy Limited (ASX:AGL) by taking the expected future cash flows and discounting them to their present value. This will be done using the Discounted Cash Flow (DCF) model. It may sound complicated, but actually it is quite simple!

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.

The Calculation

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.

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) estimate

("Est" = FCF growth rate estimated by Simply Wall St)
Present Value of 10-year Cash Flow (PVCF) = AU$2.4b

We now need to calculate the Terminal Value, which accounts for all the future cash flows after this ten year period. 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 2.3%. We discount the terminal cash flows to today's value at a cost of equity of 5.9%.

Terminal Value (TV)= FCF₂₀₃₄ × (1 + g) ÷ (r – g) = AU$292m× (1 + 2.3%) ÷ (5.9%– 2.3%) = AU$8.1b

Present Value of Terminal Value (PVTV)= TV / (1 + r)¹⁰= AU$8.1b÷ ( 1 + 5.9%)¹⁰= AU$4.6b

The total value, or equity value, is then the sum of the present value of the future cash flows, which in this case is AU$7.0b. The last step is to then divide the equity value by the number of shares outstanding. Compared to the current share price of AU$10.4, the company appears around fair value at the time of writing. Remember though, that this is just an approximate valuation, and like any complex formula - garbage in, garbage out.

The Assumptions

The calculation above is very dependent on two assumptions. The first is the discount rate and the other is the 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 AGL Energy 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 5.9%, 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 AGL Energy

Moving On:

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. Instead the best use for a DCF model is to test certain assumptions and theories to see if they would lead to the company being undervalued or overvalued. If a company grows at a different rate, or if its cost of equity or risk free rate changes sharply, the output can look very different. For AGL Energy, there are three relevant aspects you should further examine:

1. Risks: Consider for instance, the ever-present spectre of investment risk. We've identified 2 warning signs with AGL Energy , and understanding them should be part of your investment process.
