The company earned US$64.2 million in the second quarter, or 27 cents per diluted share, up from $54.3 million, or 22 cents, in the same period a year ago. Adobe also grew revenue to $320.1 million from $317.4 million last year. Excluding certain items, Adobe said it earned $66.7 million, or 28 cents per share.
