Oh, ComtechTelecommunications (NASDAQ:CMTL) management, why did you have to do it? Why did you have to keep using words like "record," "soar," "crush," and "smash" when talking about your fourth-quarter earnings? You managers are supposed to be sour, stone-faced Eeyores always talking down your results. Those hyperbolic words are supposed to come from sweaty, bug-eyed TV personalities and wacko columnists like yours truly.

That admonition aside, results for the fiscal fourth quarter did indeed look quite good. Sales jumped 66% and net income increased by a nearly similar amount, excluding a year-ago charge. Top- and bottom-line numbers were both ahead of the relatively few analyst estimates, and the quarter-end backlog was nearly double the year-ago level.

Cash flow management was also excellent for the quarter and fiscal year. Full-year free cash flow came to $46.5 million -- a 163% gain over last year. While both inventory and accounts receivable are on the upswing, so are accounts payable. Stepping back to look at the big picture, I'm not that worried about working capital management here, since the increases are not at all disproportionate to the growth of the business.

Sure, Comtech is not without competition -- the company has to deal with the likes of ViaSat (NASDAQ:VSAT), Motley Fool Hidden Gems pick Radyne (NASDAQ:RADN), and Qualcomm (NASDAQ:QCOM) -- but the segments that the company targets have considerable growth potential. In other words, even though Comtech is more than holding its own, there's room in its markets for more than just one or two companies.

Communications demand seems to show no signs of letting up; we're still in the early days of broadband and the infancy of voice over Internet protocol (VoIP). What's more, there will be ongoing demand from the military for increasingly sophisticated and secure communications systems, not to mention civilian demand for wireless and satellite communication and other applications.

Comtech is something of a rare find -- a growing high-tech company with a reasonable valuation based upon solid free cash flow. I wouldn't want to delude anyone into thinking this was a risk-free opportunity, but I do think it has a better-than-average chance of continuing to be a winner for patient investors.
