MESA, Ariz., Sept. 29, 2025 /PRNewswire/ -- Northrim Horizon ("Northrim"), an Arizona-based permanent capital investment firm, today announced its acquisition of ACG Systems ("ACG" or the "Company"), a Maryland-based systems integrator and technical service provider for mission-critical wireless communication systems in the defense, federal, and commercial industries. The Company becomes Northrim's third platform acquisition of Fund III. ACG will serve as Northrim's foundation for additional organic growth and acquisitions in the wireless communication services industry.

"Northrim is thrilled to be partnering with the ACG team," said Brad Gulbrandsen, Managing Partner at Northrim Horizon. "For three decades, ACG has been a trusted service provider to some of the world's largest commercial and government institutions. The Company has an incredible track record of service delivery for its customers across indispensable communication systems and equipment. Northrim looks forward to helping the business maintain its stellar reputation and grow into additional customer, technology, and market opportunities."

Northrim has appointed Thomas Montalbano as CEO to support the existing management team and lead the platform's expansion. Mr. Montalbano joins ACG from Mckinsey & Company. Previously, he earned an MBA from Harvard Business School and served for nearly a decade as a Marine infantry officer. Bob Dick and Tim Carney, who have co-led ACG since 2005, will stay on in their current capacities, supported by a robust and talented organization built across sales, project management, engineering, and field services.

"ACG's world-class engineering expertise has led the Company to achieve phenomenal growth over the last several years," said Crawford Gates, Principal at Northrim Horizon. "In addition, the recent increase in public recognition of the need for updated domestic wireless infrastructure and subsequent legislation to that effect should further augment that growth profile and enable ACG to be an even stronger partner to its customers. We recognize the tremendous business this team has built and Northrim is committed to building upon that foundation for decades to come."

The Company is actively pursuing opportunities to become the leading dedicated provider of integrated communication system services by forming new industry partnerships and acquiring new technologies, products, and service capabilities.

Since its founding in 1995, ACG has established a strong reputation for providing technical integration and field support services to customers across a wide range of industries, including commercial aerospace and aviation, government, defense, healthcare, and infrastructure. The Company is a true solutions provider leveraging a broad range of expertise in analog, digital, and IP communication solutions across many OEMs, making ACG an ideal service partner for system installations, upgrades, replacements, and maintenance.
