It was a year ago that Altium decided to pack its bags and relocate its headquarters and R&D to Shanghai. The company’s revenue was up 20% year-over-year in the second half of 2011, and the pretax income, excluding charges related to the move, was $4.6 million, up from a loss of $315,000 the year before.

It’s way too premature to call the move a success, but on the other hand, those who thought the PCB software company would vanish into the Chinese ether have quieted down.
