Key Insights

  • Using the 2 Stage Free Cash Flow to Equity, Alnylam Pharmaceuticals fair value estimate is US$512
  • Alnylam Pharmaceuticals is estimated to be 49% undervalued based on current share price of US$262
  • Our fair value estimate is 81% higher than Alnylam Pharmaceuticals' analyst price target of US$283

In this article we are going to estimate the intrinsic value of Alnylam Pharmaceuticals, Inc. (NASDAQ:ALNY) by taking the expected future cash flows and discounting them 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.

Remember though, that there are many ways to estimate a company's value, and a DCF is just one method. If you still have some burning questions about this type of valuation, take a look at the Simply Wall St analysis model.

The Method

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. 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:

("Est" = FCF growth rate estimated by Simply Wall St)
Present Value of 10-year Cash Flow (PVCF) = US$14b

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 (2.5%) 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 6.4%.

Terminal Value (TV)= FCF2034 × (1 + g) ÷ (r – g) = US$3.7b× (1 + 2.5%) ÷ (6.4%– 2.5%) = US$96b

Present Value of Terminal Value (PVTV)= TV / (1 + r)10= US$96b÷ ( 1 + 6.4%)10= US$52b

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$66b. 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$262, the company appears quite good value at a 49% 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

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. 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 Alnylam Pharmaceuticals 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 0.952. 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 Alnylam Pharmaceuticals

Strength
  • Debt is well covered by earnings.
Weakness
  • Shareholders have been diluted in the past year.
Opportunity
  • Has sufficient cash runway for more than 3 years based on current free cash flows.
  • Trading below our estimate of fair value by more than 20%.
Threat
  • Debt is not well covered by operating cash flow.
  • Total liabilities exceed total assets, which raises the risk of financial distress.

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. 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. Can we work out why the company is trading at a discount to intrinsic value?
