Seagate Technology Plc, maker of hard drives and storage devices, has reached an agreement to buy the former manufacturing plant and headquarters building of bankrupt Solyndra LLC, Reuters reported yesterday. The price for the building in Fremont, Calif., could not be determined. A bankruptcy court in February approved the appointment of Chicago-based Jones Lang LaSalle to market the building, which cost more than $300 million and was completed in 2010, according to court documents. At that time, the property was expected to fetch around $150 million. A final sale is subject to due diligence and the approval of the bankruptcy court.
