The hard-drive maker expects adjusted earnings per share of as much as $6 in its fiscal second quarter, well ahead of analyst expectations of $4.80, according to a statement Thursday. It also raised its dividend by 17%. Shares rose 2% in extended trading, although the stock was volatile and briefly went negative.

- Deckers Outdoor (DECK) shares are down 8.1% in extended trading after the footwear company cut its net sales guidance for the full year, which also fell short of the consensus estimate.
