@ $74.63
Significance 4

Chief Legal Officer Powell sold 36,852 shares across three trades totaling $2.75M—fifth open-market sale by this insider in 36 months.

Christopher Powell, the company's Chief Legal Officer, executed three coordinated sales on the same day, disposing of a meaningful 26% of his holdings for approximately $2.75 million. This represents his fifth open-market sale in the past three years—a consistent pattern of reducing exposure rather than accumulating shares. While the company is profitable with strong recent revenue growth, Powell's repeated selling activity stands out especially given the stock's recent strong performance (up significantly over the past three months) and trading well below its 52-week high, conditions that might normally encourage a C-suite executive to hold or buy. The timing and scale of these sales—his largest dispositions in the filing history window—suggest Powell is managing down his concentration risk rather than expressing confidence in the company's near-term direction.

Aj Teague Buy
6,175 shares
$450,652
@ $72.98
Significance 7

Director Aj Teague acquires 6,175 shares in two open-market purchases as stock rallies; perfect prior buy-timing track record across both near and long-term horizons.

Aj Teague, a director at Solaris Energy Infrastructure, has acquired over 6,000 shares in two separate open-market purchases, representing a meaningful addition to his holdings. This trade marks his 10th and 11th open-market purchase across the past three years—he has never sold shares in that window, a pattern of pure accumulation. What matters most here is his track record at this specific stock: all five of his prior purchases at SEI have been followed by stock gains, with outcomes consistently positive across both the short and long term. He is now buying again, this time into a stock that has rallied significantly over the recent quarter and sits well below its 52-week high, adding to a profitable company that is growing revenue at a rapid pace. The combination of a director repeatedly and successfully buying this stock, combined with its strong fundamentals and position well off its peak, suggests this is not panic buying but deliberate accumulation by someone whose prior judgments have consistently been vindicated.

Significance 6

Director Walker Ray N Jr sells 56,841 shares (90.8% of holdings) for $4.1M at $72.11

Director Walker Ray N Jr has divested nearly his entire stake in Solaris Energy Infrastructure, selling over 56,000 shares for approximately $4.1 million on a single transaction. This represents a substantial liquidation of his position rather than a trimming of holdings. The company itself remains financially healthy—it is profitable with strong revenue growth and posted a profitable most recent quarter, suggesting the sale is not driven by deteriorating fundamentals. However, the timing warrants attention: the stock currently trades below its 52-week high, having pulled back from its recent peak, and Ray has no open-market purchases on record over the past three years, making this his second open-market sale in that window. For a director holding significant equity, a near-complete exit is unusual and differs meaningfully from partial trims.

Significance 6

Director Keenan W Howard Jr divested entire stake, selling 2M shares for $149M while stock rallies sharply.

Keenan W Howard Jr, a member of the board of directors at Solaris Energy Infrastructure, completely exited his shareholdings by selling two million shares for $149 million. This represents a rare departure from his recent pattern—his prior 14 trades were all sales, indicating he has been a consistent seller of company stock over time, though his previous sale at this company is too recent to assess outcome. The timing of this full liquidation occurs while the stock has rallied sharply over the past three months and trades near its highs, which contrasts with the typical insider buying pattern of purchasing into weakness; instead, Howard is exiting into strength. Solaris itself is a profitable company with solid fundamentals including strong recent revenue growth, which makes this a complete exit from an operationally sound business rather than an escape from a deteriorating situation. The totality of his stake disposal—particularly in a company with encouraging financial metrics and positive price momentum—warrants monitoring to understand whether this reflects changing views on valuation or reflects director-level portfolio rebalancing decisions unrelated to company fundamentals.

Significance 2

10% institutional owner KTR Management liquidates entire 2M-share position for $141.5M, ending repeated exit pattern.

KTR Management Company, an institutional holder with a 10% beneficial ownership stake, has sold off its entire remaining position in Solaris Energy—the culmination of a consistent exit strategy over the past six months. This is the third open-market sale by this investor within the past eighteen months, though the prior two exits showed mixed timing: one well-timed to a decline and one poorly-timed to a subsequent gain. The current sale occurs while the stock trades just below its 52-week high and the company demonstrates strong fundamentals including profitable operations with accelerating revenue growth. However, the institutional holder's clear preference for reducing its stake—converting all stock compensation awards to cash before immediately selling the full position—suggests a pure portfolio management decision rather than a tactical market timing judgment. As a 10% institutional owner rather than an operative insider, KTR's actions reflect portfolio rebalancing and diversification rather than convictions about the company's direction, and the series of consecutive exits may simply indicate a planned unwinding of the position regardless of price conditions.

TEAGUE AJ Buy

@ $43.12
Significance 7

Director TEAGUE AJ bought 4,620 shares at avg $43.12 on 2025-12-17; holdings +125.2% to 8,310 shares

TEAGUE AJ, a Director at Solaris Energy Infrastructure, completed 2 separate purchases totaling 4,620 shares for $199,214.40 at a blended average price of $43.12, increasing his stake by 125.2%. His prior trades at SEI show a consistent pattern: all 4 prior buys at this ticker were well-timed, with 90-day returns ranging from +4.9% to +47.3%, and his cross-ticker track record across 6 prior buys shows a 100% win rate with an average 90-day return of +20.7%. The current stock price of $43.06 sits near the transaction price and -22.2% below the 52-week high of $55.36, placing this purchase in a period of relative price retreat. The company's fundamentals show steady performance: $166.8M in quarterly revenue, 6.9% annual growth, and a P/E of 26.91, suggesting valuation remains reasonable despite recent pullback.

Significance 5

Co-CEO Brock Amanda M purchased 3,669 shares of SEI at $40.89; current price $43.06, stock -22.2% from 52-week high.

Brock Amanda M, serving as Co-Chief Executive Officer, made an open-market purchase of 3,669 shares for a total value of $150,025.41, increasing her holdings from 137,411 shares to 141,080 shares. The transaction occurred at $40.89 per share while the current market price stands at $43.06—a modest gain of $0.6K at current valuations. The stock is currently trading -22.2% from its 52-week high of $55.36 and has moved -0.5% over the past 30 days, though it has gained +14.4% over 90 days. Fundamentals show Solaris Energy Infrastructure generated $166.8M in quarterly revenue with $14.6M net income, a +6.9% annual revenue growth rate, and a P/E of 26.91. Cross-ticker, Brock's three prior open-market sales exhibited a 100.00% well-timed rate over 90-day windows, indicating a historically disciplined execution pattern, though this metric reflects her track record across different companies and should not be assumed to predict outcomes at this ticker specifically.

Significance 5

CAO Durrett sells 47,011 shares (26.4% of holdings) at $44.62; stock down 22.2% from 52-week high

Cynthia M. Durrett, Chief Administrative Officer, sold 47,011 shares at $44.62 on 2025-12-17, reducing her holdings from 178,163 to 131,152 shares. The sale occurred at a price $1.56 above the current price of $43.06, but well below the 52-week high of $55.36. The company's fundamentals remain solid with revenue of $166,843,000.00 and net income of $14,550,000.00 in the latest quarter, supported by annual revenue growth of 6.9% and a P/E of 26.91. The 26.4% reduction in her holdings represents a material decrease in insider ownership, which investors should monitor in context of the company's recent price decline of 22.2% from its 52-week peak.

Significance 6

10% owner KTR Management Co. sells 2,114,783 shares of SEI for $106.1M at $50.15; derivative conversion trade—retains unquantified derivative holdings.

KTR Management Company, LLC, a 10% stakeholder in Solaris Energy Infrastructure, Inc., sold 2,114,783 shares (2.11M shares) for $106,056,367.45 ($106.1M) at $50.15 on 2025-11-04. This is a derivative-conversion transaction, meaning the insider's true position includes Form 4 Table II derivative securities not yet populated in our database; the zero post-transaction holding in Table I shares does not reflect the insider's complete stake. The current stock price of $53.48 stands 2.6% below the 52-week high of $54.90, while the company shows solid fundamentals (Revenue $166,843,000.00, Net income $14,550,000.00, Annual revenue growth +6.9%, P/E: 33.42). In the insider's prior trade at SEI on 2025-08-06, a sell executed at a point that preceded a 90-day gain of +82.1%—indicating poorly-timed prior execution at this ticker. The absence of timing discipline in the historical record, combined with the derivative-conversion nature of this transaction and the proximity to recent 52-week highs, warrants examination of the derivative holdings before drawing conclusions about the insider's confidence in the company's near-term trajectory.

@ $25.00
Significance 4

CFO/President Ramachandran buys 2,000 shares of SEI at $25.00 on 2025-09-09; stock down 30.7% from 52-week high.

Ramachandran Kyle S., serving as President and CFO, purchased 2,000 shares at $25.00, bringing his holdings to 370,338 shares. The purchase occurs after a significant drawdown: the stock is down 30.7% from its 52-week high of $35.96 and has declined 16.9% over the past 30 days. Against this backdrop, the company maintains stable fundamentals with revenue of $149,328,000.00 and net income of $11,955,000.00 in the latest quarter, along with 6.9% annual revenue growth and a P/E of 15.58. This open-market purchase by a senior officer during a material price decline merits attention as a signal of insider positioning, though the modest share increase (+0.5% of pre-transaction holdings) and the stock's recent momentum suggest cautious rather than aggressive accumulation.
