Npeh, LLC

10% owner Npeh, LLC sells 435,000 shares (12.8% stake reduction) at $2.44 blended price; perfectly replicated historical timing pattern.

Npeh, LLC—a 10% shareholder—executed a two-day sale of 435,000 shares (12.8% reduction from 3.4M holdings) at a blended average of $2.44, realizing $1,060,711.50. The sale mirrors a precise behavioral signature: this is the insider's sixth consecutive sell at NPWR, and all five prior trades at this ticker were well-timed against the 90-day benchmark, with the most recent sequence (January and November 2025) posting 90-day declines ranging from -17.4% to -43.0%. His cross-ticker track record of 20 prior sells shows a 100% well-timed rate at the 90-day mark (average -34.7% post-sale). The current price of $2.22 is already -57.3% from the 52-week high and the company reports $0.00 revenue (latest quarter), -$9.9M net income, and -100% annual revenue growth—a deeply distressed profile. This transaction signals continuation of a proven early-exit pattern by a material insider at a pre-revenue, cash-burning entity trading 9% below the transaction price.

10% owner NPEH LLC sells 500,000 shares of NPWR in 3 tranches (Jan 14–16) at blended $2.64; stock -73.6% from 52-week high, company unprofitable with -56.9% revenue decline.

NPEH LLC, a 10% owner, executed 3 separate sales totaling 500,000 shares for $1,322,284.50 across January 14–16, 2026, reducing its stake by -24.4% to 1,550,000 shares post-transaction. The sales occurred at a blended average price of $2.64, which is currently -73.6% below the 52-week high of $10.00, and the company remains deeply unprofitable with latest-quarter revenue of $0.00 and annual net income of -$411,498,000.00, alongside a -56.9% annual revenue decline. Across the insider's same-ticker transaction history at NPWR, all 5 prior measurable sales showed negative 30-day returns (ranging -9.7% to -29.6%), indicating a consistent pattern of selling into downward price momentum at this stock. The current 30-day price action of +12.8% represents a near-term recovery from the broader 90-day decline of -26.3%, though the fundamental backdrop of zero revenue and severe net losses raises material questions about ongoing cash burn and business viability.

10% owner NPEH, LLC sells 588,653 shares ($1.6M) across 2 transactions at $2.71 average; stock down -81.0% from 52-week high.

NPEH, LLC, a 10% shareholder in NET Power Inc., executed 2 separate sales totaling 588,653 shares for $1,593,479.47 on November 17 and 19, 2025, reducing holdings by 15.3%. The sales occurred at a blended average price of $2.71, which is now 7.1% above the current price of $2.53, and the stock trades -81.0% below its 52-week high of $13.29. NET Power is deeply unprofitable with net income of -$411,498,000 in its latest period, zero current quarterly revenue, and -56.9% annual revenue decline. The company's market cap stands at $9,520,956.72. These sales follow a pattern of five consecutive daily sells by the same filer between October 24 and October 30, 2025, suggesting systematic reduction of a major shareholding position.

NPEH LLC (10% owner) sells 902.2K shares for $3.7M across three days at blended $4.10 average, reducing stake by 32.6%.

NPEH LLC, a 10% owner of NET Power, executed three separate sales totaling 902,171 shares for $3,702,731.82 between October 28–30, 2025, at prices ranging from $3.77 to $4.12 and blended at $4.10. This represents a reduction of holdings from 2,767,417 to 1,865,246 shares, a -32.6% decrease in stake. The timing is notable: the current price of $3.97 is -70.1% from the 52-week high of $13.29, and the stock is in a volatile recovery phase (up +31.9% over 30 days, +51.0% over 90 days). However, this does not align with the insider's broader cross-ticker track record, which shows 20 prior sells with a 90-day well-timed rate of 27.27%, indicating mixed timing acumen. At NPWR specifically, the filer's five prior sales (October 21–27) are too recent to assess outcomes. Critically, NET Power's fundamentals are severely distressed: negative quarterly revenue ($0.00), a loss of $-28,142,000.00, annual revenue decline of -56.9%, and a market cap of only $14,939,999.28—indicating a cash-burned, unprofitable entity where a major shareholder's multi-million-dollar exit represents meaningful capital withdrawal during operational distress.

10% owner NPEH, LLC sells 516.7K shares in 3 transactions for $1.9M at blended avg $3.72

NPEH, LLC, a 10% shareholder, executed three separate sales totaling 516,683 shares for $1,922,281.58 between 2025-10-23 and 2025-10-27 at prices ranging from $3.69 to $3.77, reducing holdings by 15.7% from 3,284,100 to 2,767,417 shares. The sales occur in a backdrop of severe fundamental deterioration: NET Power reported $0.00 in latest-quarter revenue and net income of $-28,142,000.00, with annual revenue contraction of 56.9% and a market cap of only $13,886,296.56. The current stock price of $3.69 is down 72.2% from its 52-week high of $13.29, though it has recovered 21.8% over the past 30 days and 29.5% over 90 days. This large-scale position reduction by a significant insider holder signals material reassessment of NET Power's trajectory during a period of acute operational contraction and stock deterioration.

10% Owner NPEH LLC sells 479,300 shares ($1.7M) across 3 days at blended $3.51; stock now $3.35, down 74.8% from $13.29 high.

NPEH LLC, a 10% shareholder of NET Power Inc., executed 3 separate sales totaling 479,300 shares for $1,681,951.81 across October 20–22, at prices ranging from $3.31 to $3.58 (blended average $3.51), reducing its stake by 12.7% from 3,763,400 to 3,284,100 shares. The timing is notable: the insider's prior trades at NPWR (2 measurable sales in late November 2024) were well-timed at the 90-day mark, with declines of 36.0% and 37.1% after sale, and the insider's cross-ticker track record shows a 23.08% well-timed rate across 16 prior sells. However, NET Power Inc. faces severe fundamental headwinds: latest quarterly revenue is $0.00, full-year net income was negative at -$28,142,000, annual revenue growth declined 56.9%, and market cap stands at only $12,606,800.40. The current stock price of $3.35 represents a 74.8% decline from the 52-week high of $13.29, suggesting the market has already repriced substantial risk. Against this backdrop, a major shareholder's liquidation of nearly 13% of holdings warrants close scrutiny of whether the company can stabilize operations and achieve positive cash generation.

NPEH, LLC (10% owner) sold 236,600 shares for $1,147,218.83 at $4.85 avg; -69.4% from 52-week high after +85.8% in 30 days.

NPEH, LLC executed 3 separate sales totaling 236,600 shares for $1,147,218.83 on 2025-10-15 and 2025-10-16 at a blended average price of $4.85, reducing holdings from 4,000,000 shares to 3,763,400 shares (-5.9%). The timing is notable: the stock stands at $4.07 (current price), -69.4% from its 52-week high of $13.29, yet rebounded +85.8% over the prior 30 days and +45.9% over 90 days—suggesting the insider sold into a sharp rally after a severe drawdown. At the ticker level, 3 of NPEH's 5 prior NPWR sales (in October and November 2024) proved well-timed at the 90-day mark, with negative returns of -23.8% to -38.8%, indicating a pattern of selling before further declines. Fundamentals show the company is deeply unprofitable (net income $-28,142,000 for the latest full year, quarterly revenue $0.00) with a market cap of only $15,316,321.68, raising material questions about operational viability. The filing contains a derivative-conversion transaction; the insider's total economic position in Form 4 Table II is not yet available in the database, so this sale of 236,600 shares is a partial reduction, not a position exit.

10% owner NPEH, LLC sells entire 431,009 share stake in NPWR at $12.76 for $5.5M; complete exit from position

NPEH, LLC, a 10% shareholder of NET Power Inc., executed a complete exit of its position by selling 431,009 shares at $12.76 on 2024-11-22, reducing holdings to 0 shares. This represents a -100.0% reduction in the entity's holdings, with total proceeds of $5,499,243.83. The sale occurred within the 52-week trading range and follows an immediate prior sell on 2024-11-21; taken together with sales on 2024-11-20, 2024-10-17, 2024-10-16, and 2024-10-11, this reflects a concentrated liquidation pattern over the prior six weeks. The company's fundamentals show Revenue of $12,000.00 and Net income of $818,000.00 in the latest quarter against a market cap of $46,852,138.80, and the insider's cross-ticker track record shows 12 prior sells with an average 30-day return of +22.1%, though at NPWR specifically, prior measurable outcomes on sales (2024-10-17, 2024-10-16, and 2024-10-11) ranged from +31.4% to +77.9% at the 30-day mark. The complete liquidation of a major stakeholder position, combined with the succession of sales across multiple trading days, warrants investor scrutiny of the underlying business rationale and any material developments at NET Power.

10% owner NPEH LLC sells 829,411 shares ($10.5M) at $12.67 avg; retains 431,009 shares post-conversion

NPEH LLC, a 10% stakeholder in NET Power Inc., executed two separate sales totaling 829,411 shares for $10,508,754.76 on November 20–21, 2024, at a blended average price of $12.67. This represents a 65.8% reduction in holdings from 1,260,420 shares to 431,009 shares. The timing coincides with a 43.3% 30-day price advance and 48.9% 90-day advance; the stock is currently -4.2% from its 52-week high of $13.10. Notably, this filing contains a derivative-conversion transaction, so the reported post-sale holdings of 431,009 shares do not represent the insider's total economic position—Form 4 Table II derivatives are not yet available in the database. The prior five sales at this ticker (September–October 2024) occurred at lower price levels and subsequently experienced 30-day gains of +15.6% to +77.9%, suggesting a pattern of selling into rallies rather than at valuation peaks.

10% owner NPEH, LLC liquidates entire 716,987-share stake in NET Power (NPWR) for $5,146,332.24 across two days

NPEH, LLC, a 10% owner of NET Power, executed a complete exit of its position through 2 separate sales totaling 716,987 shares for $5,146,332.24 (blended average price $7.18) on October 16-17, 2024. The timing is notable: the company currently trades at $8.16, placing the blended execution price 12.0% below current levels, while the stock has fallen 43.9% from its 52-week high of $14.55. NET Power's fundamentals reveal severe stress—the latest quarter posted revenue of $238,000.00 and a net loss of $4,268,000.00 against a market cap of only $30,707,907.84, indicating a pre-revenue or early-stage energy company with significant burn. The complete liquidation of a major stakeholder's entire holdings signals a decisive exit rather than a portfolio rebalancing, removing a 10% anchor from the shareholder base at a time when the company's quarterly metrics show material cash drain relative to its market valuation.
