Margins matter. The more Atwood Oceanics (NYSE: ATW) keeps of each buck it earns in revenue, the more money it has to invest in growth, fund new strategic plans, or (gasp!) distribute to shareholders. That's why I check on my holdings' margins at least once a quarter. I'm looking for the absolute numbers, comparisons to sector peers and competitors, and any trend that may tell me how strong Atwood Oceanics' competitive position could be.

Here's the current margin snapshot for Atwood Oceanics and some of its sector and industry peers, and direct competitors.

Unfortunately, that chart doesn't tell us much about where Atwood Oceanics has been or where it's going. A company with rising gross and operating margins often fuels its growth by increasing demand for its products. If it sells more units while keeping costs in check, its profitability increases. Conversely, a company with gross margins that inch downward over time is often losing out to competition, and possibly engaging in a race to the bottom on prices. If it can't make up for this problem by cutting costs -- and most companies can't -- then both the business and its shares face a decidedly bleak outlook.

Of course, over the short term, the kind of economic shocks we recently experienced can drastically affect a company's profitability. That's why I like to look at five fiscal years' worth of margins, along with the results for the trailing 12 months (TTM), the last fiscal year, and last fiscal quarter (LFQ). You can't always reach a hard conclusion about your company's health, but you can better understand what to expect, and what to watch.

Here's the margin picture for Atwood Oceanics over the past few years.

(Because of seasonality in some businesses, the numbers for the last period on the right -- the TTM figures -- aren't always comparable to the FY results preceding them.)

Here's how the stats break down:

  • Over the past five years, gross margin peaked at 62.2% and averaged 52.2%. Operating margin peaked at 50.8% and averaged 36.3%. Net margin peaked at 42.8% and averaged 33%.
  • Fiscal year 2009 gross margin was 62.2%, 1,000 basis points better than the 5-year average. Fiscal year 2009 operating margin was 50.8%, 1,450 basis points better than the 5-year average. Fiscal year 2009 net margin was 42.8%, 980 basis points better than the 5-year average.
  • TTM gross margin is 61%, 880 basis points better than the 5-year average. TTM operating margin is 49%, 1,270 basis points better than the 5-year average. TTM net margin is 38.8%, 580 basis points better than the 5-year average.

With recent 12-month-period operating margins exceeding historical averages, Atwood Oceanics looks like it is doing fine.
