Power Integrations Inc (NASDAQ:POWI) Investors Are Paying Above The Intrinsic Value

In this article:

Today I will be providing a simple run-through of the discounted cash flows (DCF) method to estimate the attractiveness of Power Integrations Inc (NASDAQ:POWI) as an investment opportunity. Anyone interested in learning a bit more about intrinsic value should have a read of the Simply Wall St analysis model. If you are reading this after April 2018 then I highly recommend you check out the latest calculation for Power Integrations here.

What’s the value?

I use what is known as the 2-stage 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 start off, I took the analyst consensus estimates of POWI’s levered free cash flow (FCF) over the next five years and discounted these values at the cost of equity of 9.64%. When estimates weren’t available, I’ve extrapolated the average annual growth rate over the previous five years, capped at a reasonable level. This resulted in a present value of 5-year cash flow of US$427.20M. Want to know how I arrived at this number? Check out our detailed analysis here.

Above is a visual representation of how POWI’s earnings are expected to move going forward, which should give you an idea of POWI’s outlook. Secondly, I calculate the terminal value, which is the business’s cash flow after the first stage. I’ve decided 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. Discounting the terminal value back five years gives us a present value of US$1.28B.

The total value, or equity value, is then the sum of the present value of the cash flows, which in this case is US$1.71B. The last step is to then divide the equity value by the number of shares outstanding. This results in an intrinsic value of $57.36, which, compared to the current share price of $69.05, we see that Power Integrations is fair value, maybe slightly overvalued and not available at a discount at this time.
