PORTLAND, Ore. & PALO ALTO, Calif.–(BUSINESS WIRE)–#AIInfrastructure–ZincFive, Inc. (“ZincFive” or the “Company”), the leader in immediate power solutions for the data center and artificial intelligence (AI) infrastructure markets, powered by its proprietary nickel-zinc battery technology, today announced that it has entered into a definitive business combination agreement (“BCA”) with Spark I Acquisition Corporation (NASDAQ: SPKL) (“Spark I”), a special purpose acquisition company formed by SparkLabs Group. This proposed transaction (the “Transaction” or the “Business Combination”) represents a pro forma enterprise value of approximately $752 million and, upon completion, is expected to result in ZincFive becoming a Nasdaq-listed company under the ticker symbol ZFIV and under the name “ZincFive, Inc.”
ZincFive’s proprietary, patented nickel-zinc platform delivers superior safety, higher power density, a smaller footprint, and lower total cost of ownership, without the tradeoffs associated with lead-acid and lithium-ion batteries. ZincFive’s products eliminate thermal runaway risk while limiting cooling requirements, reducing installation costs, and enabling a more sustainable, recyclable power architecture for data centers. ZincFive believes their technology is positioned to address the accelerating build-out of global data center markets and the emerging need for short-duration, high-power solutions for advanced AI infrastructure designs.
ZincFive has already achieved commercial scale, with nearly 2 gigawatts (GW) of systems deployed and contracted globally and annual revenue doubling from 2024 to approximately $66.9 million in 2025. ZincFive’s approximately $81 million backlog as of December 31, 2025 reflects accelerating demand in data centers where ZincFive’s products deliver immediate, repeatable high-power response without compromising safety, reliability, or operating economics.
ZincFive recently launched a comprehensive energy storage solution engineered to support both outage duration backup functionality and real-time AI dynamic power loads, positioning the Company at the forefront of next-generation data center power infrastructure.
“This milestone reflects the strength of ZincFive’s technology, partnerships, and global momentum,” said Tod Higinbotham, CEO of ZincFive. “Demand for safe, high-performance power is accelerating worldwide, and we’ve built a differentiated platform designed to scale. With trusted partners and customers alongside us, we believe we are well positioned to expand globally and deliver long-term value as the data center market continues to evolve.”
“ZincFive was built on a belief that chemistry choices matter,” said Tim Hysell, co-founder, board member and strategic advisor of ZincFive. “By pairing that belief with relentless execution, we’ve built a high-power platform that customers trust – demonstrating that safer, more sustainable infrastructure can be delivered at scale. We believe the proposed Transaction with Spark I will provide the capital and public market platform to amplify our impact globally.”
“This proposed Transaction with ZincFive aligns with Spark I’s strategy to bring transformative, late-stage technology companies tied to the global innovation economy to the U.S. public markets,” said James Rhee, CEO and Chairman of Spark I. “We believe ZincFive’s proven commercial relationships, recently-launched AI power solutions, and scalable manufacturing position the Company to capture significant value from the AI infrastructure build-out. We believe the market fundamentals, technology leadership, and execution capability create a compelling public market opportunity.”
Transaction Overview
The proposed Business Combination is expected to deliver gross proceeds of at least $100 million from a committed PIPE, which fully satisfies the BCA’s minimum cash condition, and up to $25 million in additional proceeds depending on redemptions. Existing ZincFive shareholders are expected to roll 100% of their equity into the combined public company. ZincFive has entered into a $35 million bridge loan facility of which $28.5 million is expected to be repaid at the closing of the Transaction. Net proceeds from the transaction will be used to fund ZincFive’s growth investments, commercial deployment, and build-out of U.S. manufacturing.
The Boards of Directors of both ZincFive and Spark I have unanimously approved the proposed Transaction, which is expected to close in the second half of 2026, subject to customary closing conditions, including approval by Spark I shareholders and regulatory review.
All transaction figures referenced herein are preliminary and subject to the final terms of the Business Combination.
