The last business cycle was not kind to this company. Vicon appears to operate in an extremely competitive industry, as there are constant downward pricing pressures that result in tiny or negative margins. A large chunk of revenues must be spent on R&D just to keep up with the competition, some of which are several times larger than Vicon.
The company derives much of its revenues from installations in newly completed buildings and renovations, which makes Vicon's business cycle lag that of the general economy. (Since recently completed buildings still need security during recessions, the company had been profitable up until the last quarter. But since few building/renovation projects are started during recessions, Vicon sees its revenues drop a few quarters later, when those buildings would have been completed.)
As such, the company hit a wall in the last calendar quarter of 2009, as the lack of newly completed buildings/renovations finally caught up to the company: sales (year-over-year) were down almost 30% to $11 million. However, the company's situation is not as poor as the sales record would indicate. While the company's sales were just $11 million, it recorded orders (i.e. future revenue, likely) of over $13 million for the 2nd straight quarter.
The company appears willing to use its cash reserves to prop up its share price, as the company has been buying back shares at a decent rate, with plans to continue to do so. An important caveat, however, is a pending lawsuit on the company for patent infringement; to its credit, the company has been successfully defending itself, but the plaintiff continues to escalate its appeals.
The stock does have a margin of safety from an asset point of view. But both the long-term and short-term earnings situations are murky (thanks to the competition and the cyclical situation, respectively), making this a tough decision for value investors!
