Otovo Completes Acquisition of SunSystem Technology for $1.3 Million, Bringing Service Platform to Approximately 30% of The United States

SST is the seventh acquisition Otovo has closed since its December 2025 merger, part of a disciplined program to build national scale in distributed energy services

HOUSTON, TX, July 2, 2026 – Otovo ASA (Euronext Oslo Børs: OTOVO) today announced the completion of its acquisition of SunSystem Technology, LLC ("SST"), a national provider of operations and maintenance (“O&M”) services for distributed generation assets. The closing follows the letter of intent announced in June 2026 and marks the seventh acquisition Otovo has completed since December 2025.

With the close, SST's 14-state operating footprint is now fully part of Otovo's national platform, giving the company true coast-to-coast coverage across the United States.

Highlights • The aggregate maximum earn-out is $1.3 million, comprised of a $200,000 cash closing payment, plus an additional earn-out based on net income from operations in the United States, payable through the end of 2028. • The earn-out consideration will be allocated between cash and shares, with the first $300,000 of aggregate earn-out payments being paid entirely in cash and the next $300,000 being paid as a seller credit convertible into shares. Any aggregate earn-out payment exceeding $600,000 will be paid 50% in cash and 50% as a seller credit convertible into shares. • SST's operations, technicians, and customer relationships transfer to Otovo’s umbrella effective immediately. • SST's field operations are now being onboarded onto the Endurance® AI platform, extending automated intake, dispatch, scheduling and supply chain coordination to a 14-state footprint. • Closing completes the seventh transaction in Otovo's post-merger acquisition program, reinforcing the company's track record of integrating acquired businesses quickly and profitably.

"Closing SST is a milestone for Otovo, as it proves out the acquisition model we've been running since December," said William J. (John) Berger, CEO of Otovo. "Every deal we've closed has added scale, technology leverage and profitable revenue to the platform, and SST is no exception. We're now positioned to serve solar, storage, and EV charging customers nationwide, backed by Endurance® and a growing team that knows how to deliver reliable service at scale."

"We're excited to officially join the Otovo team," said Matt Alestra, CEO of SunSystem Technology. "This closing lets us move quickly. Our customers will start seeing the benefits of Otovo's AI-driven platform right away, without any disruption to the high level of service they count on from SST."
