I have to disagree somewhat with this...for a couple reasons:
Net Present Value (NPV) is an indication of whether an investment is positive value or negative value to the investor. It gives no indication of whether a particular investment is better or worse than other investments, and also gives no indication of whether an investment is a good investment for the business (only that it's positive value); in other words, it doesn't take into account the opportunity cost of the investment.
A good example here is that a couple years ago, when Microsoft had about $50B in the bank, and didn't know what to do with it, a number of people (some very smart) suggested that Microsoft should start a bank, and literally start making consumer loans. If you had done an NPV or discounted cash flow analysis, you certainly would have found it to come out positive (indicating that this is an investment that should be considered). But, had Microsoft done this, they would have seen lower returns on their $50B investment than would have been acceptable to shareholders, and it likely would have reduced the value of the company. A decision based on NPV in this case would have been a very bad one.
The other problem with using NPV for large, strategic investments is that it's success is highly predicated on being able to accurately determine the discount rate, which is the discounted future value of income. So, if you can put your investment in a CD earning 5%, the discount rate is at least 5%. But, how do you know how much you could potentially be earning on that money if you don't know all your potential investment opportunities? And, more importantly, the discount rate is likely to change year-over-year, and (unless you're Warren Buffet who claims he can do it) it's very difficult to estimate changing discount rates.
Lastly, NPV doesn't take into account risk. Some people like to adjust the discount rate to account for risk, but -- as can be proved mathematically -- adjusting the discount rate to account for risk doesn't work as expected. So, risk needs to be accounted for in other ways.
Anyway, NPV certainly has it's place, but it's more appropriately used to evaluate project investments, not large-scale corporate acquisitions.
That said, I do agree that there are better ways to value a company than using multiples (it has many of the same issues as NPV and discounted cash flow analysis), but funny enough, in my experience, the complicated math and financial analysis is often not much better than someone with experience going with the basic financial statements and their gut.
I also agree with you that these are important concepts that all investors should be thoroughly familiar with!
Just my $.02...
