"We are excited to welcome such a talented team of professionals to HGST, where their inventive spirit will be embraced and encouraged."

"This merger will enable our world-class engineering team and IP to continue to make a significant contribution to the high-performance enterprise SSD space that has long been sTec's focus." The board of directors of sTec, on the unanimous recommendation of a special committee of independent directors of the board, has unanimously approved the merger agreement and has resolved to recommend that sTec shareholders approve the transaction at a sTec shareholders meeting to be held to approve the merger agreement and the merger.
