NRGV Energy Vault Holdings, Inc. Insider Trading

CEO Robert Piconi bought 12,500 NRGV shares at $3.21 (31 Mar 2026); 4 of 4 prior buys at this ticker yielded positive 90d returns (+4.2% to +124.7%).

Robert Piconi, Chief Executive Officer, purchased 12,500 shares at $3.21 on 2026-03-31, expanding his holdings to 16.92M shares. The current price of $3.40 reflects the stock trading -44.0% from its 52-week high of $6.07. Piconi's prior trade history at NRGV shows a consistent pattern: all 4 prior buy transactions with measurable 90-day outcomes produced positive returns, ranging from +4.2% to +124.7%, indicating well-timed entry points at the 90-day mark. Against this backdrop, his purchase follows a 30-day gain of +4.6% and 90-day decline of -26.2%, suggesting he is accumulating during a period of downward pressure. His cross-ticker track record of 10 prior open-market buys averaged +38.8% over 30 days and +72.9% over 90 days with an 87.50% win rate, though same-ticker outcomes are the more relevant comparison. The company remains unprofitable (net income $-26.8M in the latest quarter), though revenue grew +340.9% year-over-year, providing context for both the depressed valuation and the insider's timing rationale.

Director Mandanas Mary Beth buys 5,000 shares of NRGV at $3.65; stock down -42.0% from 52-week high but +13.9% in 30 days

Director Mandanas Mary Beth purchased 5,000 shares at $3.65 on 2026-03-25, expanding her holdings to 350,838 shares (+1.4%). The purchase occurs with the stock trading at $3.52, down -42.0% from its 52-week high of $6.07 but up +13.9% over the past 30 days. Notably, her prior purchase at this same ticker on 2025-09-11 delivered a +62.8% 30-day return and +127.1% 90-day return, establishing a track record of well-timed entry points at NRGV. The company reports substantial revenue growth of +340.9% year-over-year and a current market cap of $608.9M, though it remains unprofitable with a net loss of $-26.8M in the latest quarter. The timing context suggests an insider buying during a period of recent price recovery following a significant drawdown from peak valuations.

Director Ertel Thomas R bought 5,450 shares of NRGV at $3.37; stock down -45.0% from 52-week high amid -86.5% annual revenue decline.

Director Ertel Thomas R purchased 5,450 shares at $3.37 on 2026-03-04, increasing his holdings to 365,788 shares (+1.5%). The transaction occurs as the stock is trading at $3.34, down -45.0% from its 52-week high of $6.07 and -35.0% over the past 30 days. The company fundamentals are deteriorating: annual revenue contracted -86.5%, the latest quarter generated $33.3M in revenue against a $-26.8M net loss, and market cap stands at $560.4M with no recent profitability. Most notably, this buy is part of a cluster pattern—3 other insiders also purchased shares within the past 14 days. Ertel's prior two purchases at NRGV (on 2025-08-28 and 2025-08-11) both posted positive 90-day returns (+67.8% and +145.2% respectively), suggesting a pattern of well-timed accumulation at this ticker. However, the current deteriorating fundamentals, steep recent stock decline (-35% in 30 days), and coordinated insider buying at depressed valuations warrant close examination of whether this multi-insider activity reflects informed conviction or reflects external context not yet reflected in public filings.

COO Ladwa Akshay bought 4,000 shares at $3.08; company down -86.5% YoY revenue, -$26.8M net income; 3 other insiders also bought past 14 days.

Ladwa Akshay, the Chief Operating Officer, purchased 4,000 shares at $3.08 on 2026-03-02, with post-transaction holdings of 1,824,384 shares. This purchase occurs within a cluster pattern: 3 other insiders also bought within the past 14 days. The stock is trading at $3.35 (current), down 27.2% over 30 days and 44.8% below its 52-week high of $6.07. The company's fundamentals are under pressure: annual revenue contracted -86.5% year-over-year to $33.3M in the latest quarter, and net income was negative at -$26.8M. The concurrent buying by multiple insiders amid severe revenue decline and ongoing losses suggests insiders are willing to accumulate despite deteriorating operational metrics. Whether this reflects strategic confidence in turnaround prospects or represents obligatory accumulation under a plan cannot be determined from the filing alone.

Director Paulson Larry bought 5,000 shares of NRGV at $3.15 (2026-02-27); 3 other insiders bought within 14 days amid -86.5% annual revenue decline

Paulson Larry, a Director, purchased 5,000 shares at $3.15 on 2026-02-27 for $15,726.00, adding to holdings of 501,768 shares post-transaction. The buy occurs in a company facing severe financial stress: annual revenue contracted -86.5% year-over-year, the latest quarterly revenue was $33.3M against a net loss of $26.8M, and the stock has declined -30.8% over 30 days and -46.5% from its 52-week high of $6.07. Notably, 2 other insiders also bought within the preceding 14 days, forming a cluster pattern. While Paulson's cross-ticker track record shows 100% 90-day win rate across 3 prior buys with +131.3% average 90-day return, his same-ticker history at NRGV demonstrates 3 prior purchases all with positive 90-day outcomes (+56.3%, +70.2%, +66.0% respectively), though the current price of $3.25 reflects a material decline from transaction date and a stock under acute revenue and profitability pressure.

NRGV CEO buys 7,500 shares at $3.26; stock down 44.0% from 52-week high, extends pattern of 5 prior buys all showing positive 90d returns.

CEO Robert Piconi purchased 7,500 shares at $3.26, bringing his holdings to 20.09M shares. The stock is trading at $3.40 but has fallen 44.0% from its 52-week high of $6.07 and is down 34.7% over the past 30 days. Notably, his prior 5 purchases at NRGV showed a perfect 5 of 5 timing pattern, with all exhibiting positive 90-day returns ranging from +4.2% to +124.7%, and his cross-ticker buy track record shows 87.50% win rate over 90 days with average returns of +72.9%. The purchase occurs against a backdrop of negative fundamentals: the company recorded a net loss of $26.8M in the latest quarter, annual revenue declined 86.5%, and market cap stands at $570.5M. The transaction's significance lies in the timing—coming after steep recent declines—and the insider's historical accuracy with prior purchases at this specific ticker.

SOFTBANK VISION FUND sells 3,000,000 shares of NRGV at $5.65; stake reduced 16.2% to 15.54M shares

SOFTBANK VISION FUND (10% owner) sold 3,000,000 shares on 2026-01-15 for $16,950,000.00, reducing its stake from 18.54M to 15.54M shares—a reduction of 16.2% of pre-transaction holdings. The sale occurred during a period of strong recent price momentum: the stock has risen 19.5% over the past 30 days and 72.0% over the past 90 days, though it currently trades 5.9% below the 52-week high of $6.07. NRGV fundamentals show significant distress: the company posted a net loss of $26.8M in the latest quarter on revenue of $33.3M, with annual revenue declining 86.5% year-over-year and an unprofitable full-year result. A major venture stakeholder's reduction in its position by over one-sixth—even as the stock has experienced recent strength—suggests material reassessment of the company's trajectory amid deteriorating financial performance.

NRGV CEO Piconi buys 10,000 shares at $3.00; stock down 29.6% from 52-week high as company posts $-26.8M loss on $33.3M revenue.

Piconi Robert, CEO of Energy Vault Holdings, purchased 10,000 shares at $3.00, bringing his total holdings to 20.21M shares. The company is facing significant operational headwinds: annual revenue has contracted 86.5% year-over-year, the latest quarterly revenue stands at $33.3M, and full-year net income was negative at $-26.8M. The stock is currently trading at $3.10, down 29.6% from its 52-week high of $4.40, placing it near the lower end of its 52-week range ($0.63–$4.40). While Piconi's cross-ticker buy history shows an average 90-day return of +49.4% across 8 prior transactions, his same-ticker history at NRGV consists entirely of recent trades (all within the last 3 months) with measurable 30-day outcomes ranging from +24.1% to +77.6%, but no 90-day outcomes yet available for any of them. The $30.0K transaction represents a marginal increase of 10,000 shares against an already massive 20.20M-share base. Without clarity on whether this purchase reflects operational confidence or routine portfolio management, investors should monitor the company's path to profitability and near-term revenue stabilization against the backdrop of the recent sharp price decline.

CEO Piconi bought 17,500 shares of NRGV at $3.02 on 2025-09-19 (total $52.9K); stock up 92.0% in 30 days amid cluster buying

Robert Piconi, CEO, purchased 17,500 shares at $3.02, bringing his total holdings to 20.20M shares. This buy occurs during a period of sharp momentum—the stock has rallied 92.0% over the past 30 days and 285.9% over 90 days, now trading at the 52-week high of $3.11. Notably, Piconi executed 5 separate purchases at NRGV within the past month (including buys on 2025-09-17, 2025-09-16, 2025-08-29, 2025-08-28, and the current 2025-09-19 transaction), and 2 other insiders also bought within the past 14 days, forming a cluster acquisition pattern. However, the fundamental backdrop remains weak: the company reported $-34.9M net income in its latest quarter, annual revenue declined 86.5% year-over-year, and the company remains unprofitable. The rapid sequential purchases by the CEO during a steep price run-up, combined with deteriorating financial metrics, present a layered signal that warrants investor attention to both the timing dynamics and the operational health underlying these acquisitions.

Director Paulson Larry bought 20,000 NRGV shares at $2.40; stock +232.6% in 90 days amid revenue -86.5% and cluster buying.

Paulson Larry, a Director, purchased 20,000 shares at $2.40 on 2025-09-18, expanding his holdings from 315.6K to 335.6K shares (+6.3%). The purchase occurred after the stock surged +232.6% over 90 days and currently trades at $2.68, near its 52-week high. However, the company's fundamentals remain severely challenged: annual revenue declined -86.5% year-over-year with only $8.5M in latest quarterly revenue, and the company posted a $-34.9M net loss over its most recent full fiscal year. A cluster pattern emerged with 2 other insiders also buying within the past 14 days. Paulson's prior trades at NRGV (buys on 2025-08-28 and 2025-08-13) showed one measurable 30-day return of +66.0%, though overall timing outcomes across his cross-ticker track record remain unproven at the 90-day mark. The timing of this purchase—following an extreme rally and amid deteriorating financial metrics—merits attention despite the insider cluster activity.
