Spectrotel and AireSpring to Merge to Create a Leading Managed Network Services Platform

Combination, backed by Charlesbank and Grain, creates a differentiated, scaled managed network services platform with global connectivity and advanced capabilities to drive accelerated growth.

Neptune, NJ, April 23, 2026 — Spectrotel Holding, LLC (“Spectrotel” or the “Company”), a leading provider of managed network services and connectivity solutions, today announced that it will merge with AireSpring, a premier provider of global connectivity, managed services, and network infrastructure solutions.

Spectrotel also announced a new strategic investment led by Charlesbank Capital Partners (“Charlesbank”) in order to support the Company’s next phase of growth, including the planned combination with AireSpring. Grain Management (“Grain”) will continue to back the combined platform through a reinvestment in the Company, and members of the Lonstein family, the founders of AireSpring, will remain significant minority investors. Spectrotel Chief Executive Officer Ross Artale will continue in his role as Chief Executive Officer to lead the combined business.

Together, Spectrotel and AireSpring will be better positioned to support a broader range of customer segments, from SMB and mid-market organizations to complex, distributed enterprise environments, with a wider suite of targeted connectivity solutions. By combining Spectrotel’s strengths in distributed enterprise networking and managed network services with AireSpring’s experience in global connectivity, facility-based network assets, geo-redundant voice infrastructure, and nationwide fiber capabilities, the combined organization is expected to deliver a more comprehensive and scalable platform for customers and partners with greater control over network performance, resiliency, and service delivery.

“We believe that merging with AireSpring will meaningfully expand our capabilities through enhanced global reach, infrastructure, and deep technical expertise that complement our leadership in distributed enterprise and managed services,” said Ross Artale, Spectrotel CEO. “With Charlesbank’s partnership and Grain’s continued support, we will be even better equipped to reduce complexity, improve performance, and drive better business outcomes for our customers.”

“We built AireSpring with a long-term commitment to our partners and a belief that the indirect channel deserves a provider that is fully aligned with its success,” said Avi Lonstein, Co-Founder of AireSpring. “Our combination with Spectrotel prioritizes the best possible outcomes for our customers, partners, and team members. With both organizations dedicated to outstanding customer satisfaction and absolutely committed to the channel, we are confident the experience will be not only preserved, but meaningfully enhanced.”

Strategic Rationale and Combined Strengths

The combination of Spectrotel and AireSpring will create a powerful platform designed to meet the growing demands of modern enterprises with several key differentiators:

• Global Connectivity with Greater Network Control

AireSpring’s global network reach, anchored by its nationwide facility-based fiber network and geo-redundant voice infrastructure, enables more direct control over network performance and service delivery, reducing dependency on third parties and improving consistency, resiliency, and speed of issue resolution across locations.

• Purpose-Built for Distributed Enterprise Environments

Spectrotel’s strength in supporting multi-location networks will be paired with deeper infrastructure capabilities, enabling more reliable connectivity at critical sites, regional hubs, and edge locations where performance and uptime directly impact business operations.

• Intelligent Managed Network Services with Real Operational Impact

The combined platform advances beyond traditional monitoring by integrating automation, observability, and AI-driven intelligence to identify issues earlier, accelerate remediation, and reduce downtime – all of which are expected to drive measurable improvements in network performance and user experience.

• Expanded Opportunity for Channel Partners

With stronger alignment across SMB, mid-market, and distributed enterprise segments, partners will be well-positioned to capture opportunities with solutions tailored to specific customer needs, supported by deeper technical expertise and a platform designed to deliver consistent outcomes at scale.
