A Fremont electronics manufacturer just spent $181 million buying up two office and production campuses in the East Bay, cementing its bet that demand for AI hardware will keep growing. WisLab EMS, the company behind the deals, now owns its longtime headquarters building on Starboard Drive outright and has added a sprawling three-building campus on Warm Springs Boulevard to its local footprint.
WisLab EMS paid $61 million in May for the building at 4211 Starboard Drive, which serves as its headquarters and primary production center. The Mercury News reports the site as 126,000 square feet, while Taiwan Stock Exchange filings give its area as 129,808 square feet, according to The Mercury News. The company had actually been leasing that same building since May 2024, under an agreement that was terminated once the all-cash purchase closed, according to Taiwan Stock Exchange filings. Then, on September 4, the company closed on a second, much larger acquisition: a three-building campus at 48021, 48105 and 48133 Warm Springs Boulevard for $120 million, per Alameda County property records cited in the same Mercury News report.
A Rebranded Manufacturer With Deep Pockets
WisLab EMS is owned by Taiwan-based Wistron Corp., an electronics and manufacturing firm, and the Fremont operation traces back to Alpha EMS, a Silicon Valley contract manufacturer founded in 2002. Wistron acquired Alpha EMS in May 2024 through a $15.5 million capital injection before renaming the business WisLab EMS in 2025 to align with the parent company's global brand, according to WisLab EMS. Since the acquisition, Wistron has invested millions of dollars upgrading the Starboard Drive headquarters, the same report notes.
The newly acquired Warm Springs campus totals 299,000 square feet, according to Colliers marketing materials referenced in the Mercury News report. That campus isn't new to advanced manufacturing: 48021 Warm Springs Blvd opened in September 2018 as a 110,000-square-foot headquarters and fulfillment center for supply chain manager ALOM Technologies, according to ALOM Technologies. Both Fremont transactions were completed as all-cash deals, per public real estate records cited by the Mercury News.
Cleanroom Capability and a Hiring Push
WisLab EMS makes products supporting mission-critical computing and communications, including storage, wireless broadband systems, high-performance networks, and data security encryption, according to the Mercury News report. The company's primary Fremont site features an ISO Class 8 particle-controlled cleanroom environment and upgraded equipment, per WisLab EMS. The headquarters and production center currently employs 125 or more people, and the company is recruiting for industrial engineer, quality engineer, procurement coordinator and mechanical assembler roles as it seeks additional employees in Fremont.
Part of a Much Bigger Global Buildout
The Fremont purchases fit into a far larger pattern at Wistron. The parent company opened a $700 million, 324,000-square-foot manufacturing facility in Fort Worth, Texas, in July 2026 to build Nvidia Blackwell AI supercomputers, creating up to 1,000 jobs as part of an aggressive North American expansion, according to Manufacturing Dive. Hoodline previously reported on that project in Nvidia's AllianceTexas landing, part of a broader trend that has also included Wistron's earlier Texas expansion and a subsidiary's server deal in Socorro.
A global depositary receipt offering from Wistron was reported at $1.5 billion to fund international raw material purchases and support surging AI server manufacturing capacity. The capital raise comes as Wistron focuses on expanding its AI server manufacturing capacity.
Why Fremont Keeps Drawing Advanced Manufacturers
Fremont's Warm Springs Innovation District, anchored by the Tesla Factory, is home to major advanced manufacturing operations for Tesla, Zoox, Seagate and Western Digital. Fremont also attracts employers in technology and advanced manufacturing.
That local strength lines up with broader regional technology activity, even amid technology job cuts nationally. For now, WisLab EMS's leap from tenant to property owner suggests the company expects that momentum, and its own AI-driven growth, to keep going.
