Gainers

Seagate Technology PLC (STX) stock grew 9.38 percent to $17.49 in after-market trading. The company expects second quarter revenues of about $2.8 billion, while Wall Street predicts $2.64 billion. The company now expects to ship about 43 million units of hard disk drives for the second quarter, matching a previous forecast of 41 million to 45 million units. For the second quarter, it expects gross margin to be 150 to 300 basis points above the high-end of its long-term, targeted gross margin range of 22 percent to 26 percent. The company said its guidance excludes expenses related to the acquisition of Samsung Electronics Co., Ltd's hard disk drive business and any revenue or operating expenses of the acquired business after the closing date, which cannot be estimated at this time. The company still expects to close the acquisition of Samsung's hard disk drive business by the end of December.

Looking ahead to the third quarter, Seagate anticipates revenues of at least $3.75 billion, while Wall Street predicts $3.24 billion and unit shipments to increase sequentially. The company expects third-quarter gross margins to be at least 300 basis points above the targeted range of 22 percent to 26 percent. The third quarter outlook assumes the Samsung acquisition closes in December, excludes certain costs related to the integration of the acquired Samsung hard disk drive operations, which cannot be estimated at this time. Seagate said it continues to believe hard disk drive supply will be significantly constrained for several quarters, as a result of extensive flooding in Thailand. The company said its component and disk drive factories in Thailand have not been directly affected by the flood but its ability to make hard disk drives has been impacted due to external component supply constraints.
