ZincFive Acquisition

ZincFive was acquired by Spark I Acquisition for $752M on 10 June 2026.

Before the acquisition ZincFive had raised $163M across 10 funding rounds.

ZincFive, a developer of high-power nickel-zinc battery solutions for data centers and AI infrastructure, has agreed to merge with Spark I Acquisition Corporation in a transaction valued at $600 million pre-money, resulting in a pro forma enterprise value of $752 million. The deal is expected to deliver approximately $125 million in gross proceeds, anchored by a $100 million committed PIPE and up to $25 million from Spark I's trust account, fully satisfying the minimum cash requirement. Closing is targeted for the second half of 2026, with ZincFive set to list on Nasdaq under the ticker ZFIV. The strategic rationale centers on accelerating global growth and building U.S. manufacturing capabilities to support the rapidly expanding demand for immediate power solutions in AI infrastructure. ZincFive has achieved commercial scale with nearly 2 gigawatts of systems shipped or contracted globally and closed 2025 with an $81 million commercial backlog from diversified blue-chip and hyperscale customers. The company's revenue doubled from 2024 to 2025, reaching approximately $66.9 million. The transaction includes a $35 million bridge loan facility, with $28.5 million expected to be repaid at closing, and net proceeds will fund growth investments and commercial deployment.

DateStageInvestorsRaisedDeal Summary
Dec 2025Series FClimate Investment; Japan Energy Fund; Clear Creek Investments; Helios Climate Ventures; General Venture Capital$30MZincFive, a global leader in nickel-zinc (NiZn) battery-based solutions for immediate power applications, closed an oversubscribed $30 million Series F funding round in December 2025, bringing its total funding since 2016 to $254 million. The round was backed by investors including Helios Climate Ventures, Climate Investment, Japan Energy Fund, General Ventures, and Clear Creek Investments. The funds will accelerate commercial expansion and manufacturing capacity to meet surging demand for AI data center power solutions, particularly following the launch of its BC 2 AI nickel-zinc UPS battery cabinet, which offers AI load support, zero thermal runaway risk, and 96% recyclability. The company has deployed or contracted nearly 2 GW of NiZn battery backup cabinets across the global data center industry, with commitments from leading hyperscalers and operators. ZincFive's technology provides superior power density, inherent safety, and sustainability compared to lead-acid and lithium-ion alternatives, maintaining conductivity in weak cells with minimal maintenance and a compact environmental footprint. Strategic relationships with OEMs position it for growth in AI-ready infrastructure. This Series F follows a $54 million Series D in 2022 led by Helios Climate Ventures. ZincFive emphasizes commercial maturity, scaling production to fulfill contracts amid the AI infrastructure buildout, where power systems are a critical bottleneck. The energy storage sector saw $2.8 billion in VC funding across 56 deals in 9M and Q3 2025, up 4% YoY.
Dec 2022Series DHelios Climate Ventures (lead); Climate Investment; Japan Energy Fund; Clear Creek Investments; Standard Industries; Senator Investment Group$54MZincFive, a Portland, Oregon-based company specializing in nickel-zinc battery solutions for immediate power applications like data center UPS, intelligent transportation, industrial engine starting, EV charging, and microgrids, raised $54 million in its Series D funding round in November/December 2022. The round was led by Helios Climate Ventures, with participation from existing investors Senator Investment Group and Standard Investments, and new investors including OGCI Climate Investments (also referred to as Climate Investment), Japan Energy Fund, and others such as Clear Creek Investments. This brought the company's total funding since inception to $139 million. The funds were allocated to expand market penetration in existing segments, accelerate high-volume production capacity to meet growing customer demand, invest in channel and product development, and enter new high-power energy segments and geographies. ZincFive highlighted its nickel-zinc technology's advantages: high power density, full recyclability, low carbon footprint, nonflammability, and sustained conductivity even in weakened cells, outperforming alternatives in safety, sustainability, and performance for mission-critical uses. Investors praised the spiking commercial demand, expanding customer roster including hyperscalers, and lower climate impact compared to other battery chemistries. At the time, ZincFive was deploying or contracting nearly battery backup solutions for critical infrastructure, including a Wyoming data center project with 37-39kWh cabinets supporting 30MW IT loads and a microgrid partnership with Kaizen Clean Energy and PowerCell. The round aligned with a broader 44% decline in energy storage VC funding in 9M 2022 to $4 billion across 73 deals. Subsequent developments included a Series F round raising $30 million in 2024 (total funding to $254 million) and debt financing in May/June 2024, reflecting ongoing scaling amid recognition like TIME’s GreenTech lists and Edison Awards.
Mar 2022Series A-$11MZincFive develops nickel-zinc battery-based solutions for immediate power applications, targeting mission-critical uses in data centers, transportation, and industrial sectors. The company raised $54 million in its Series D funding round announced in November 2022, led by Helios Climate Ventures with participation from Senator Investment Group, Standard Investments, OGCI Climate Investments, and Japan Energy Fund. This brought total funding to $139 million since inception in 2016. The capital supports market penetration, product development, geographic expansion, and scaling high-volume production capacity. Earlier in 2022, ZincFive completed another Series D tranche of $11.31 million on February 15, as part of the overall Series D efforts totaling around $54 million across tranches in February and November. The funding accelerates deployment in high-power energy segments amid growing demand. ZincFive has since progressed, raising a $30 million oversubscribed Series F round in late 2025, bringing total funding to $254 million to scale manufacturing for AI data center power solutions, with nearly 2 GW of nickel-zinc battery backup cabinets deployed or contracted.
