Kulr Technology Group, Inc. is a U.S.–based public company (NYSE American: KULR) founded in 2013, specialising in cutting-edge thermal management solutions for lithium-ion batteries, electronics, aerospace, defence, and energy storage. Its product suite includes technologies like KULR ONE, SafeCASE, VIBE, and thermal runaway shields—serving high-demand applications across NASA, the U.S. Navy, cloud computing, electric vehicles, and 5G communications. From its origins rooted in carbon-fibre thermals, KULR has grown to become a leader in battery safety, quality-control systems, and advanced energy management—leveraging its hardware expertise to enable safer, more sustainable electrified infrastructure.
In December 2024, KULR launched a bold “Bitcoin-first” treasury strategy, authorising up to 90% of surplus cash reserves to be allocated to Bitcoin as a reserve asset. Since then, its Bitcoin holdings have grown rapidly: kicking off with around 217 BTC (approximately $21 million) in late 2024, rising to roughly 610 BTC ($60 million) by February 2025, and reaching approximately 800 BTC ($78 million) by May 2025. KULR measures the success of this strategy via a self-defined KPI called "BTC Yield"—the growth of BTC holdings relative to its fully diluted share count—reporting yields exceeding 220% year-to-date. Echoing MicroStrategy’s approach, the company frames Bitcoin as both a hedge against inflation and a tool for long-term shareholder value, while acknowledging the volatility risks and need for disciplined treasury management.
