ABM has announced a definitive agreement to acquire WGNSTAR, a leading provider of managed workforce solutions and equipment support services for the semiconductor and high-technology industries, in a cash transaction valued at approximately $275 million.
WGNSTAR operates across the U.S. and in Ireland, delivering technical and operational solutions through a highly skilled workforce of more than 1,300 employees and long-standing client partnerships, many exceeding two decades. WGNSTAR generates over half of its revenue from integrated workforce programs, delivering highly trained technical teams to ensure operational efficiency in chip fabrication facilities. WGNSTAR also collaborates with leading OEMs to offer equipment support services that encompass installation, maintenance, and production tool management, further enhancing productivity within fabrication environments.
The growth potential in WGNSTAR’s core services is anticipated to be significant, with a multi-billion-dollar addressable market in which only a small share is currently outsourced. This creates a meaningful opportunity for ABM to expand its presence within the rapidly growing semiconductor sector. Following the acquisition, ABM’s semiconductor solutions portfolio will be approximately $325 million in revenue on an annualised basis, establishing the Company among the largest integrated service providers in North America. This strategic positioning allows ABM to pursue growth driven by U.S. semiconductor onshoring initiatives, supported by CHIPS Act incentives and record levels of private investment.
Scott Salmirs, President & Chief Executive Officer of ABM, commented: “WGNSTAR’s expertise in semiconductor operations and equipment services will align seamlessly with ABM’s strengths in engineering, energy resiliency, and mission-critical solutions. As demand escalates for domestic semiconductor production, we anticipate this transaction will uniquely position ABM to meet our clients’ evolving needs, from cleanroom and critical facility management to specialised technical services supporting chip fabrication and equipment operations. We’re excited to welcome the talented WGNSTAR team to ABM and, together, provide integrated solutions in a dynamic and rapidly growing market.”
Nigel Wenden, CEO of WGNSTAR, said: “I am incredibly proud of the business our team has built over the past 22 years since its founding in Ireland. Joining forces with ABM will enable us to better serve our clients in this exciting technology market with integrated and innovative solutions. Both companies share a commitment to innovation, excellence, and partnership, positioning us to meet the needs of our customers as the semiconductor industry continues to expand.”
The transaction is expected to close during ABM’s second fiscal quarter of 2026, following required regulatory review in the U.S. and Ireland and satisfaction of other customary conditions.

Building Management Systems (BMS) have long been used to control the heart of a building – monitoring and controlling its essential systems such as lighting, ventilation, heating and air conditioning. Facilities Managers want the best visibility to help detect and deal with concerns before they become issues.
This webinar brings together the experts from energy network provider, E.ON along with FM thought leaders to discuss moving from a reactive service to a proactive service. By identifying energy issues early and automatically, instead of occupants reporting issues, then potential faults can be identified early and remedied. The BMS does this before the problem occurs by using smart alerting and EMC support services.
Panel:
- Sara Bean: Editor FMJ (Facilities Management Journal)
- Nick Westlake: Energy and Service Delivery Manager at E.ON Control Solutions
- Sunil Shah, the author of IWFM’s Energy Management Good Practice Guide and MD of Acclaro Advisory
- David Cermak, Regional Facilities Manager for David Lloyd Clubs
