Fortunately I happen to be pursuing an MS in Finance and am a complete finance nerd. Let me explain how they can get that number. :)
I reversed engineered the assumptions they are using through shear guess and check (it was my second guess, lol). You can get a value of $7,373,520 by assuming a net profit margin of 70%, a growth rate of 0%, and a required rate of return of 10% per year.
Here's how they could calculate it: Assume HeadFi is making $87,780 in sales per month.
Multiply that number by 12 to get annual sales of $1,053,360.
Now, HeadFi has expenses it needs to pay from that revenue. Through shear guessing I found they could be assuming that 70% of revenue becomes profit.
So, now you have profits equal to 70% of $1,053,360 ...or $737,352 per year (and expenses of roughly $300,000 per year).
Now...how much will an investor pay for the
$737,352 per year HeadFi allegedly generates? If the investor requires a return of 10% per year - and assumes 0% earnings growth per year - the investor will pay $737,352/0.10....which equals the magic $7,373,520. Alternatively, you can the increase the required return up to 11% and earnings growth up to 1% and get the same answer (or [12%, 2%], [13%, 3%]....basically anything that makes the denominator equal to 0.1....search for the Gordon Growth Formula if you really want to know).
Keep in mind that a model is only as good as the assumptions/inputs. I'm oversimplifying due to limited information (and posting space, lol). I'm very skeptical that HeadFi makes $87,780 in sales per month. Also, net margins of 70% seems aggressive and earnings growth of 0% seems conservative. Similarly, I'd think an investor would require returns MUCH higher than 10% per year to compensate for the riskiness of HeadFi's advertisement model. If I had to guess I think $7 million is a bit excessive.
Hope that helps!
EDIT: Okay, their methodology is crack. It values Rotten Tomatoes at $3 million. Hmm....so Jude can sell HeadFi, buy Rotten Tomatoes, and still have $4 million leftover? I'd don't think so. Also it values Amazon.com at $151 million...when the stock market currently has it trading at $53 BILLION. It lists Google.com at $2 billion when the market has it at $146 billion.
