First Citizens' SVB unit provides $9.5M growth debt to Realta Fusion to preserve equity

Bank backs fusion startup with growth debt to preserve equity

On Feb. 17, 2026, Silicon Valley Bank, a division of First Citizens Bank, announces a $9.5 million growth capital facility to Realta Fusion to accelerate commercialization of the company’s CoSMo fusion magnetic mirror system. The financing is structured as debt to preserve founder and investor equity, reflecting First Citizens’ continued focus on serving technology and clean‑energy companies in innovation hubs across the United States. Dennis Grunt, Managing Director of Technology and Healthcare Banking at SVB, says the bank is "thrilled to support Realta" as it scales toward a future source of industrial heat and power.

The facility highlights First Citizens’ wider strategy of providing tailored capital to venture‑backed engineering firms while managing balance‑sheet exposure through debt instruments rather than equity stakes. By choosing a debt structure, SVB aims to maintain relationships with existing venture investors and deploy growth capital that supports technical milestones without diluting ownership. The move also signals the bank’s appetite for supporting advanced energy projects that target decarbonization of heavy industry, a priority area for commercial lenders seeking long‑term corporate clients in data centers, chemical processing, metal recycling and remote mining.

For First Citizens, the Realta deal reinforces its niche as a commercial bank to technology and life‑science ventures, and as a bridge between venture capital investors and companies moving from lab to pilot scale. The financing helps Realta continue to derisk the physics of its approach — trapping super‑heated hydrogen between magnetic mirrors to induce fusion — while giving the bank exposure to a potential industrial customer base for future lending, deposits and treasury services. SVB’s presence in innovation centers and its work with private equity and venture capital clients positions First Citizens to capture additional business as Realta and similar firms scale.

Technical background and funding context

Realta’s CoSMo fusion technology stems from a University of Wisconsin–Madison experiment funded by ARPA‑E that first confines plasma using high‑temperature superconducting magnets at a world‑record 17 Tesla field. The system aims to deliver carbon‑free heat or electricity on‑site for heavy industrial use.

Realta recently closes a $36 million Series A led by Future Ventures, with participation from Khosla Ventures and earlier backers; CEO and co‑founder Kieran Furlong stresses the company’s continuing capital needs despite pursuing a lower‑capital fusion pathway.
