ABM has announced a definitive agreement to acquire WGNSTAR, a 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 US and Ireland, delivering technical and operational services through a workforce of more than 1,300 employees. The business has long-standing client relationships, many spanning more than 20 years, and generates over half of its revenue from integrated workforce programmes that supply highly trained technical teams to support operations within semiconductor fabrication facilities.
In addition to workforce solutions, WGNSTAR works closely with leading original equipment manufacturers to deliver equipment support services, including installation, maintenance and production tool management. These services are designed to improve productivity and reliability in complex fabrication environments.
ABM said the growth potential within WGNSTAR’s core markets is significant, with a multi-billion-dollar addressable market where only a small proportion of services are currently outsourced. The acquisition is expected to strengthen ABM’s position within the fast-growing semiconductor sector. Following completion, ABM’s semiconductor solutions portfolio is forecast to generate approximately $325 million in annualised revenue, positioning the company as one of the largest integrated service providers in North America.
The deal aligns with broader industry trends, including increased US semiconductor onshoring supported by CHIPS Act incentives and record levels of private investment. ABM said this strategic positioning will allow it to pursue further growth as demand for domestic semiconductor manufacturing capacity accelerates.
Scott Salmirs, President and 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 specialized 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.”
ABM said the acquisition reinforces its strategy to expand higher-value, mission-critical services and deepen its capabilities in sectors aligned with long-term technology and infrastructure investment.
