ABM Acquires WGNSTAR for Tech Maintenance Biz

NEW YORK -- ABM, a provider of integrated facility, infrastructure, and technical solutions, has reached a deal 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 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 annualized 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.

“WGNSTAR’s expertise in semiconductor operations and equipment services will align seamlessly with ABM’s strengths in engineering, energy resiliency, and mission-critical solutions,” said Scott Salmirs, president and CEO of ABM.

“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.”

WGNSTAR is expected to generate annual revenue of approximately $135 million in calendar 2025, with adjusted EBITDA margins in excess of ABM’s Manufacturing & Distribution (“M&D”) segment, along with an anticipated annual growth rate of about 10%.

The transaction will be funded through a combination of cash on hand and existing credit facilities. 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.

ABM (NYSE: ABM) is one of the world’s largest providers of integrated facility, engineering, and infrastructure solutions.
