# Nano Nuclear Energy Chairman Yu Jiang Sells $30M in NNE Stock — Insiders Unload $69M Combined

> Nano Nuclear Energy Chairman Yu Jiang sold $30M in NNE through his holding entity, while CEO Walker sold $6.6M and CFO Garcha sold $2.6M — totaling $69.3M in insider selling from the nuclear micro-reactor company.

Nano Nuclear Energy insiders sold a staggering $69.3 million in NNE stock in early 2026, led by Chairman and President Yu Jiang who sold $30 million through his holding entity I Financial Ventures Group LLC. CEO James John Walker added $6.64 million in sales, and CFO Jaisun Garcha sold $2.55 million. $69M From Three Insiders Insider Title Transactions Value Career Sales Shares After Yu Jiang President & Chairman 10 $30.03M $55.7M 8,724,000 James John Walker Chief Executive Officer 6 $6.64M $7.4M 250,000 Jaisun Garcha Chief Financial Officer 3 $2.55M $2.6M 250,000 Total: 3 insiders, 19 transactions $69.26M $65.7M Chairman Yu: $55.7M Career, Still the Largest Holder Yu Jiang sold through I Financial Ventures Group LLC — his personal holding entity. Despite selling $55.7 million in career proceeds, he retains 8.72 million shares. At current prices, that remaining position is worth several hundred million dollars, so the selling represents a modest percentage of his total holdings. However, the pace of monetization is notable. The $30M February sale is his largest yet, suggesting increased urgency to convert paper gains into cash. CEO Walker: 90% of Career Sales in This Round CEO James Walker sold $6.64M against a career total of $7.4M — meaning nearly 90% of his lifetime insider sales happened in this single window. He's left with 250,000 shares, down from a much larger position. For a CEO, this level of position reduction is aggressive. CFO Garcha: Nearly All Career Sales Now CFO Jaisun Garcha shows a similar pattern: $2.55M sold against a $2.6M career total. Like Walker, almost all of his selling happened recently. He also retains 250,000 shares — identical to the CEO's remaining position, suggesting coordinated retention targets. The Nuclear Micro-Reactor Story Nano Nuclear Energy develops portable nuclear micro-reactors — small modular reactors designed for remote locations, military applications, and decentralized power generation. The company is part of the broader nuclear energy renaissance driven by AI data center power demands. Like Oklo (whose co-founders we also covered selling $30M in mirror-image amounts), NNE represents the speculative end of the nuclear energy spectrum. The stock has benefited from enormous enthusiasm about next-generation nuclear power, but the company is pre-revenue with reactors still in development. Two Nuclear Startups, Same Pattern The parallels between NNE and Oklo's insider selling are striking: Oklo: Co-founders sold $30M (each $15M), career total $359M combined NNE: Chairman sold $30M, CEO $6.6M, CFO $2.6M, total $69M Both pre-revenue nuclear technology companies Both driven by AI power demand narrative Both founders aggressively monetizing before first commercial reactor deployment For NNE investors, the pattern is clear: the people building these nuclear reactors are taking substantial cash off the table while the AI-driven enthusiasm for nuclear power keeps share prices elevated. Whether that's prudent diversification or a commentary on the timeline to commercial revenue is the question every NNE shareholder needs to answer for themselves.
