Drugmakers are an interesting bunch.

On the one hand, they get multi-year patent protection on new drugs, many of which become the preferred treatment for everything from heart disease to cancer. All of that means steady profits, because even in recessions, people buy their medicantions.

On the other hand, drugmakers must continually be filling the pipeline to ensure that they always have lucrative and profitable products under patent protection. That entails not just money but risk, as one never knows if a given candidate will actually turn into an effective -- and safe -- product.

It's important to keep track of revenue, but free cash flow gives us a better sense of what the company is doing with that revenue -- and whether they'll have the funds to invest in the business later.

But the bread and butter of drugmakers is the pipeline -- those drugs in development and trials that can generate patent-protected profits for years on end. And a robust pipeline depends on robust R&D expenditures.
