The Integrated Solution Supports the Explosion of AI Workloads with Owned and Operated Data Centers with Dedicated Power Generation

San Diego, California--(Newsfile Corp. - June 25, 2025) - Sonim Technologies, Inc. (NASDAQ: SONM), a leading provider of rugged mobile solutions, today announced the signing of a non-binding Letter of Intent (LOI) for a proposed reverse take-over (RTO) with a private US-based company (the "Target") building out Nvidia-based High-Performance Computing (HPC) A.I. factories to support the hyper growth of cloud-based artificial intelligence (AI) workloads.

Key terms of the proposed transaction include:

• The LOI outlines the framework for a strategic business combination pursuant to which stockholders of the HPC A.I. factory Target would own a majority in the combined company.

• Sonim stockholders would retain equity valued at $17.5 million in the combined company.

• The HPC A.I. factory Target would be valued at approximately $300 million, with the valuation expected to be supported by a fairness opinion from an independent third party.

• Following the closing, the combined company is expected to adopt a new corporate name and ticker symbol while maintaining its listing on Nasdaq.

Sonim believes that, when combined with the previously announced sale of substantially all of its operating assets for $15 million (plus an additional earn-out of $5 million), the proposed RTO transaction will maximize stockholder value and provide a compelling path forward for Sonim's strategic evolution.

The Target is poised for significant growth by focusing on High-Performance Computing as a Service (HPCaaS). By leveraging their owned data centers, they aim to accelerate expansion, lower operational risks, and tap into the high-margin, fast-growing AI factory market. With plans to activate thousands of GPUs in 2025, they're positioning themselves to meet surging demand for the utility of the future, "Intelligence as a Service."

The global demand for AI-ready high-performance computing factory capacity is projected to grow at an average annual rate of 33% through 2030, with AI workloads driving up to 70% of total demand¹. AI infrastructure spending is expected to exceed $200 billion by 2028, underscoring the transformative potential of this market². To meet this surging demand, leading data center players are preparing to invest $1.8 trillion from 2024 to 2030, driven by traditional enterprise workloads (55% of demand in 2028) and the explosive growth of GenAI, which will account for 60% of total demand growth during this period³. In the U.S., initiatives such as Executive Order 14141 and a $500 billion private joint venture aim to bolster domestic AI infrastructure, with Congress emphasizing AI infrastructure as a strategic national asset⁴.

"This transaction positions Sonim stockholders to benefit from the tremendous growth of the AI revolution and represents a transformational step for Sonim and its stockholders," said Mike Mulica, Chair of the Special Committee for Sonim. "The RTO structure allows us to align with a forward-thinking partner in the AI and digital transformation space, leveraging their expertise to create a market-leading, technology-driven enterprise. At the same time, the CVR ensures our stockholders benefit from the successful transition of our legacy business."

The LOI is non-binding, and the transaction is further subject to customary closing conditions, regulatory approval, approval by Sonim stockholders and the completion of the Sonim Legacy Business Sale. The parties intend to finalize the definitive agreement and proceed with securing necessary approvals in a timely manner.
