VICOR CORP

Our corporate headquarters building in Andover, Massachusetts, which we own, provides approximately 90,000 square feet of office space for our sales, marketing, engineering, and administrative personnel. We also own a building of approximately 320,000 square feet (which includes the 90,000 square foot expansion described below) in Andover, Massachusetts, which houses all Massachusetts manufacturing activities.

Current capital investments are focused on the expansion of manufacturing capacity for the production of Advanced Products at our Andover facility. During 2020, we began construction of a two-story addition to our Andover manufacturing facility to expand the Advanced Products production area by approximately 90,000 square feet. Completion of the construction and production had been delayed from 2021 to 2023. We took occupancy of this addition during the first half of 2022 and the completion of the installation of advanced plating operations was completed in 2023.

We own a single-story industrial building of approximately 31,000 square feet in Sunnyvale, California, which we have leased on a long-term basis to a corporate tenant, which has occupied the building since June 2016. We are currently negotiating with such corporate tenant regarding the renewal of this lease.

All other domestic and foreign facilities are leased from third-party lessors on arms’ length terms. We believe our owned and leased facilities are adequate for our foreseeable needs.
