Margins matter. The more ADTRAN (Nasdaq: ADTN) 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 Adtran's competitive position could be.

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

Unfortunately, that table doesn't tell us much about where Adtran 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, the last fiscal year, and last fiscal quarter. 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 Adtran 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 59.7% and averaged 59.3%. Operating margin peaked at 28.1% and averaged 23.3%. Net margin peaked at 19.7% and averaged 16.7%.
  • TTM gross margin is 59%, 30 basis points worse than the five-year average. TTM operating margin is 22.5%, 80 basis points worse than the five-year average. TTM net margin is 16.3%, 40 basis points worse than the five-year average.

With recent TTM operating margins below historical averages, Adtran has some work to do. There may be some hope in the last quarter's results, but only time will tell.
