Margins matter. The more Garmin (Nasdaq: GRMN) 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 Garmin's competitive position could be.

Here's the current margin snapshot for Garmin and peers.

Unfortunately, that chart doesn't tell us much about where Garmin 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 Garmin 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 52.1% and averaged 48.3%. Operating margin peaked at 32.9% and averaged 28.8%. Net margin peaked at 30.3% and averaged 26.2%.
  • Fiscal year 2009 gross margin was 49%, 70 basis points better than the five-year average. Fiscal year 2009 operating margin was 26.7%, 210 basis points worse than the five-year average. Fiscal year 2009 net margin was 23.9%, 230 basis points worse than the five-year average.
  • TTM gross margin is 51.7%, 340 basis points better than the five-year average. TTM operating margin is 27.7%, 110 basis points worse than the five-year average. TTM net margin is 22.6%, 360 basis points worse than the five-year average.
  • LFQ gross margin is 53.7%, 120 basis points better than the prior-year quarter. LFQ operating margin is 27.7%, 210 basis points worse than the prior-year quarter. LFQ net margin is 18.5%, 570 basis points worse than the prior-year quarter.

With recent 12-month-period operating margins below historical averages, Garmin has some work to do. There may be some hope in the last quarter's results, but only time will tell.
