RuggedCom, a maker of ruggedized networking devices for the power sector, has announced plans to list publicly on the Toronto Stock Exchange and filed its preliminary prospectus on the proposed offering. This Toronto-area company has been dubbed the "Cisco of the smart grid" because its products enable the move toward an electricity system that is automated, self-healing and, ultimately, intelligent. Specifically, RuggedCom develops ethernet switches and routers that can handle the two-way flow of immense amounts of data, and at the same time operate reliably in harsh environments where high-voltage power spikes and extreme temperatures can render standard networking equipment useless or unreliable. I wrote about RuggedCom in the Star last August.

The company is growing like wildfire, as you'll see from the prospectus, and it's highly profitable, making it a great candidate for an IPO. It's good to see.
