Is Eli Lilly's Stock Cheap by the Numbers?

Numbers can lie -- yet they're the best first step in determining whether a stock is a buy. In this series, we use some carefully chosen metrics to size up a stock's true value based on the following clues:

  • The current price multiples.
  • The consistency of past earnings and cash flow.
  • The amount of growth we can expect.

Let's see what those numbers can tell us about how expensive or cheap Eli Lilly (NYS: LLY) might be.

The current price multiples
First, we'll look at most investors' favorite metric: the price-to-earnings ratio. It divides the company's share price by its earnings per share (EPS). The lower the P/E, the better.

Then we'll take things up a notch with a more advanced metric: enterprise value to unlevered free cash flow. This tool divides the company's enterprise value (basically, its market cap plus its debt, minus its cash) by its unlevered free cash flow (its free cash flow, adding back the interest payments on its debt). As with the P/E, the lower this number is, the better.

Analysts argue about which is more important -- earnings or cash flow. Who cares? A good buy ideally has low multiples on both.

Eli Lilly has a P/E ratio of 9.1 and an EV/FCF ratio of 6.5 over the trailing 12 months. If we stretch and compare current valuations with the five-year averages for earnings and free cash flow, we see that Eli Lilly has a P/E ratio of 15.9 and a five-year EV/FCF ratio of 8.3.

A positive one-year ratio of less than 10 for both metrics is ideal. For a five-year metric, less than 20 is ideal.

Eli Lilly is a mouthwatering 4-for4 on hitting the ideal targets, but let's see how it stacks up against some of its competitors and industry mates.

Numerically, we've seen how Eli Lilly's valuation rates on both an absolute and relative basis. Next, let's examine ...

The consistency of past earnings and cash flow
An ideal company will be consistently strong in its earnings and cash-flow generation.

In the past five years, Eli Lilly's net income margin has ranged from -7.8% to 19.7%. In that same time frame, unlevered free cash flow margin has ranged from 20.5% to 28.1%.

How do those figures compare with those of the company's peers? See for yourself:

In addition, over the past five years, Eli Lilly has tallied up four years of positive earnings and five years of positive free cash flow.

Next, let's figure out ...

How much growth we can expect
Analysts tend to comically overstate their five-year growth estimates. If you accept them at face value, you willoverpay for stocks. But even though you should definitely take the analysts' prognostications with a grain of salt, they can still provide a useful starting point when compared with similar numbers from a company's closest rivals.

Let's start by seeing what this company's done over the past five years. In that time period, Eli Lilly has put up past EPS growth rates of 7.8%. Meanwhile, Wall Street's analysts expect future growth rates of -8.0%.

The bottom line
The pile of numbers we've plowed through has shown us the price multiples that shares of Eli Lilly are trading at, the volatility of its operational performance, and what kind of growth profile it has -- both on an absolute and a relative basis.

The more consistent a company's performance has been and the more growth we can expect, the more we should be willing to pay. We've gone well beyond looking at a 9.1 P/E ratio, and we see some good and some bad. The price multiples are quite cheap. When you look at the margin range, the negative earnings year was in 2008. This was due to an expensing of almost $5 billion of in-process R&D in conjunction with its acquisition of ImClone. When we get to the past growth and future outlook for growth, we see why Lilly and its peers have been trading at discounts to their past profitability. Drug pipelines are the key factor to evaluate. If you find Eli Lilly's numbers or story compelling, don't stop here. Continue your due-diligence process until you're confident one way or the other.
