Is 3M Healthy Enough to Invest In?

The company isn't going anywhere, that's for sure. But there's one yellow flag you need to know about before you buy in.

The best linebacker on earth can still find himself sidelined by a microscopic flu virus. The same is true for companies: Even the biggest and strongest can be brought to their knees if they don't stay financially healthy.

Nobody can argue that 3M (MMM 0.03%) isn't both big and strong. A member of the Dow Jones Industrial Average and one of the largest conglomerates in the United States, the company also benefits from a lack of large competitors and a recognizable brand. In these ways, it's similar to its peers, General Electric (GE 0.01%) and Honeywell International (HON 0.25%).

But if its balance sheet isn't healthy enough, it simply may not be worth the investment.

Raking in the dough
One major factor in determining financial health is to see whether the company is profitable. Of course, in some cases -- especially in the tech sector -- a healthy company may not necessarily be profitable. Amazon is a famous example.But for a mature, traditional company like 3M, lack of profitability would be a huge red flag.

Fortunately for investors, 3M is very profitable, even compared to its conglomerate peers. While the TTM gross margins of GE and Honeywell are nearly identical, 3M's is almost 20% higher:

3M's net profit margins are similarly outstanding: 16%, compared to 12.4% for Honeywell and just 5.1% for GE (although GE's low profit margin is a bit misleading: It's nosedived since the company began its restructuring efforts in early 2015). One thing's for sure, though: 3M's margins are best-in-class.

Where the money goes
Big profit margins don't mean much, though, if those profits are being eaten up by capital expenditures. And manufacturing is a notoriously capital-intense business. However, all three companies are churning out enough cash to cover their capital expenditures. The following chart shows the companies' annual cash-flow-to-capex ratios over the last five years:

While GE's number has bounced around, Honeywell's and 3M's have been steadier, and generally on an upward trajectory -- which is good. That means the companies are generating more and more cash relative to their capital expenditures.

Debt 
Of course, if the money a company generates is going to its creditors instead of back into the business, it's not of much use to shareholders. That's why it's essential to keep an eye on debt. There are several metrics available to look at debt, but let's check out the debt-to-capital ratios of these companies over the last five years:

Uh oh. Here's the first sign of trouble for 3M: Its debt-to-capital ratio has increased significantly over the past year as it has taken on long-term debt to finance share buybacks and its dividend.

This isn't necessarily a bad thing. Taking advantage of low interest rates can be a sensible move, particularly if a company can deploy the cash effectively. What should give you pause, though, is that 3M isn't showing any signs of letting up on its debt financing.

In early February, the company announced a dividend increase and up to $10 billion in share buybacks. But at the end of 2015, it only had $1.8 billion in cash on hand. So if those buybacks occur this year, they would need to be financed through additional debt, even as interest rates are rising. And with a current P/E ratio of more than 21 -- higher than Honeywell's 18.7 and GE's 16.8 -- it's hard to see how 3M shares are any kind of a bargain.

Now, just because the board has approved $10 billion in buybacks doesn't mean the company will necessarily follow through immediately (it could, for example, space them out over several years or decline to purchase the full amount altogether), but it's clearly something you should keep an eye on.

The Foolish bottom line
3M is certainly a profitable company that generates sufficient cash to fund its operations and its capital needs. Investors should still be concerned about its comparatively high long-term debt load coupled with its plans to buy back more shares. While this isn't enough reason to sell or avoid the stock in and of itself, it's definitely worth watching.

You may want to wait to see how management proceeds before buying in. A short-term pop in stock price due to share buybacks isn't worth years of struggles with higher interest payments.
