The British chip designer continued last year's growth streak with a 45 percent surge in quarterly normalized pre-tax profits compared to Q4 2010. Revenues also rose by 21 percent to £137.8 million ($217 million) -- not bad for a company that started out with twelve engineers in a barn . There's nothing complicated about CEO Warren East's explanation of the results -- he simply says that his company sold more designs to "more new customers" and also raked in more royalties from existing deals. Unless the global economies suffers badly in 2012, ARM says it expects to meet market expectations, targeting an annual profit of $860 million this year.
