FREMONT, Calif., May 28, 2026 — Nextpower™ (Nasdaq: NXT), a leading provider of solar and power technology solutions for utility-scale power plants, today announced it has entered into a definitive agreement to acquire Prevalon Energy, a U.S.-headquartered joint venture between Mitsubishi Power Americas and EES, for total consideration of up to $365 million, not including cash to be acquired, comprising cash and stock. Closing of the transaction is subject to customary closing conditions, including antitrust regulatory review.

The acquisition is expected to extend Nextpower’s technology platform across BESS and intelligent controls for critical power infrastructure. The Company projects that the global demand for BESS outside China could represent an opportunity of up to $35 billion by 2030, with the U.S. comprising up to $15 billion.

In connection with the transaction, Nextpower is raising its fiscal year 2027 outlook, which assumes the successful closing of the transaction. Nextpower now expects fiscal 2027 revenue of approximately $4.0 billion to $4.4 billion, compared to its prior outlook of $3.8 billion to $4.1 billion, and adjusted EBITDA of approximately $845 million to $930 million, compared to its prior outlook of $825 million to $900 million. Nextpower will provide additional details on its updated outlook during an investor conference call later today.

“Prevalon was the perfect choice for Nextpower to expand into BESS,” said Markus Wilhelm, founder and CEO of Strata Energy. “Both companies are technology focused and understand power, utilities, and complex use cases for customers. Prevalon’s BESS hardware and software platform solves challenging problems for utility-connected and self-powered AI data centers, including inertia support, grid stabilization, contingency management, and GPU AI workload smoothing. This is a differentiated, competitive advantage that Nextpower’s customers will value.”

Strata was one of the early movers in BESS, delivering over a dozen utility-scale BESS projects since 2018.

“Many of our customers have rapidly expanded their storage programs and asked us to extend Nextpower’s platform into power conversion and BESS to deliver fully integrated firm power solutions,” said Dan Shugar, founder and CEO of Nextpower. “Together with our recently announced and complementary power conversion acquisition, we expect that Prevalon’s BESS platform will open new market opportunities for Nextpower in AI data center power supply applications. Prevalon is already engaged with large hyperscalers with a lean, seasoned team that has a solid track record delivering BESS for utilities and IPPs across a variety of use cases.”

Prevalon’s BESS technology supports applications where power quality, rapid response, and deployment speed are critical, including AI data centers, private grids, grid-connected storage, and industrial power systems. Its Hybrid Power Stabilizer is designed to manage rapid load changes and support grid stability, while its HD5™ DC block and newly released HD5™ AC block products provide modular energy storage building blocks supported by insightOS controls, monitoring, diagnostics, and long-term service capabilities.

“Prevalon shares Nextpower’s relentless focus on innovation, quality, reliability, and customer success,” said Tom Cornell, President and CEO of Prevalon Energy. “Operating as part of Nextpower, we can leverage their global reach and deep client relationships. Our customers will benefit from doing business with a reliable, investment-grade partner with decades of experience in power generation and management.”

The acquisition continues Nextpower’s evolution to a comprehensive, integrated energy technology platform spanning structural systems, electrical infrastructure, power conversion, storage, controls, automation, and software. Earlier this month, Nextpower entered into a definitive agreement to acquire key power conversion technology used to store and dispatch electricity reliably and efficiently.

The transaction is expected to close in Q2 FY27, subject to customary regulatory approvals and closing conditions.

FY2027 Annual Outlook

Updated outlook includes planned incremental costs of approximately $50 million related to the acceleration of our entry into the power conversion market.  Adjusted EBITDA range of $845 million to $930 million excludes approximately $208 million for stock-based compensation, net intangible amortization, and acquisition related costs.  Adjusted Diluted EPS range of $4.30 to $4.73 excludes approximately $1.09 for stock-based compensation, net intangible amortization, and acquisition related costs, net of impacts for tax.
