Investors Are Undervaluing ImmunoGen Inc (NASDAQ:IMGN) By 44.20%, Here Is My Intrinsic Value Calculation

In this article I am going to calculate the intrinsic value of ImmunoGen Inc (NASDAQ:IMGN) using the discounted cash flows (DCF) model. If you want to learn more about this method, the basis for my calculations can be found in detail in the Simply Wall St analysis model. If you are reading this after February 2018 then I highly recommend you check out the latest calculation for ImmunoGen here.

Crunching the numbers

I use what is known as the 2-stage model, which takes into account the initial higher growth stage of a company’s life cycle and the steadier growth phase over the long run. Firstly, I use the analyst consensus forecast of IMGN’s levered free cash flow (FCF) over the next five years and discounted these values at the rate of 11.33%. This resulted in a present value of 5-year cash flow of $-93.1M. Keen to understand how I calculated this value? Read our detailed analysis here.

Above is a visual representation of how IMGN’s earnings are expected to move going forward, which should give you an idea of IMGN’s outlook. Next, I determine the terminal value, which accounts for all the future cash flows after the five years. It’s appropriate to use the 10-year government bond rate of 2.8% as the stable growth rate, which is rightly below GDP growth, but more towards the conservative side. After discounting the terminal value back five years, the present value becomes $2,169.4M.

The total value is the sum of cash flows for the next five years and the discounted terminal value, which results in the Total Equity Value, which in this case is $2,076.3M. To get the intrinsic value per share, we divide this by the total number of shares outstanding. This results in an intrinsic value of $15.70, which, compared to the current share price of $8.76, we find that ImmunoGen is quite undervalued at a 44.20% discount to what it is available for right now.

Whilst important, DCF calculation shouldn’t be the only metric you look at when researching a company. What is the reason for the share price to differ from the intrinsic value? For IMGN, I’ve put together three key aspects you should further research:
