SUNNYVALE — Apple is poised to deepen its presence in Silicon Valley with two deals in Sunnyvale that extend a remarkable string of transactions involving property purchases and building rentals.
The tech titan, which is expanding in the South Bay, has struck a deal to sublease a full office building at 625 North Mary Ave. in Sunnyvale, according to several sources with knowledge of the rental deal. Proofpoint is the tenant in the 625 North Mary building and subleased the offices to Apple.
Cupertino-based Apple is also in talks for a real estate transaction involving an office building at 684 West Maude Ave. that is the first phase of an office campus in Sunnyvale known as Catalyst, sources with knowledge of these discussions say.
LinkedIn currently leases the 684 West Maude office building. An affiliate of Germany-based Union Investment Real Estate GmbH and Seattle-based Metzler Real Estate Advisors owns the building, which is at the corner of West Maude and North Pastoria.
It wasn’t immediately clear whether the discussions would result in a rental deal or purchase by Apple.
The 625 North Mary building totals 121,200 square feet, according to a marketing brochure prepared by Cushman & Wakefield commercial real estate brokers Brandon Bain, Erik Hallgrimson, Joe Brady, and Mike Drew.
Apple’s sublease deal with Proofpoint on North Mary is complete, although a move-in time frame wasn’t immediately known.
The iPhone maker also has been busy purchasing several office properties in the South Bay this year.
Apple has paid about $1.1 billion so far in 2025 to buy an array of properties in Santa Clara County, including:
• On June 24, Apple paid $166.9 million for a three-building Cupertino office campus at 10200 North Tantau Ave. that totals roughly 220,700 square feet. PGIM, which manages real estate and other assets for Prudential Financial, sold the campus.
• On June 26, Apple paid $350 million for the Mathilda Commons office campus in Sunnyvale. The 382,500-square-foot, two-building campus is at 615 and 625 North Mathilda Ave. Veteran real estate development firm Jay Paul Co. was the seller.
• On Sept. 25, Apple paid $365 million to buy a Sunnyvale office campus. That campus totals 636,500 square feet and has addresses of 505 and 555 North Mathilda and 605 West Maude Ave. Kilroy Real Estate sold the property.
• On Dec. 11, Apple paid $216 million for two office buildings at 19319 and 19339 Stevens Creek Blvd. in Cupertino. These buildings together total 265,000 square feet.
Upon completing its purchase of the two Stevens Creek office buildings in Cupertino, Apple noted its deep and widening ties to the South Bay.
“The Santa Clara Valley has been our home for nearly 50 years, and we’re proud to continue investing in world-class facilities here that are designed to foster innovation and collaboration amongst our team members in support of our customers around the world,” Kristina Raspe, Apple’s vice president of Global Real Estate and Facilities, said in comments the company emailed to this news organization.
