I was digging through old materials, and tracing back as far as 1988, they have been profitable for the last 20 years...with the EXCEPTION of 1993, in which they had "hic-cups" from POS installations, getting a new buyer, etc., and lost a couple million. (There was also a small net loss in 1997, but that includes $33 million in "recapitalization charges" from their going private transaction, which had NOTHING to do with the core business, which was very profitable that year.)
Who knows for how many consecutive years prior to 1988 TUES was profitable?
This model has strength and staying power. It's absurdly underpriced at these levels.
