They beat Street revenue estimates of $83.8M by $4.8M, or 5.7%. With revenue only $1.8M less than last quarter, the Street eps estimate of 9 cents looks very low compared to last quarter's 18 cents. Thus today's upgrade by Caris.

No increase in company annual guidance, but they are conservative and can always beat later.
