GLIBK GCI Liberty, Inc. Insider Trading

CEO Ronald A Duncan purchases 67,500 shares for $1,420,516.50 across 4 transactions at $21.04–$21.11 as stock trades at $20.71, down 49.7% from 52-week high.

Ronald A Duncan, President and CEO, executed 4 separate purchases totaling 67,500 shares for $1,420,516.50 on June 3, 2026, at prices ranging from $21.01 to $21.11 with a blended average of $21.04. The timing is noteworthy: the stock currently trades at $20.71, representing a 49.7% decline from its 52-week high of $41.18 and a 45.0% decline over the past 90 days. The company's underlying fundamentals show mixed signals—it generated $256.0M in quarterly revenue with $18.0M net income, but was unprofitable over its most recent full fiscal year despite modest 3.0% annual revenue growth. This substantial personal investment by the CEO during a sharp drawdown warrants attention to both the company's near-term operational outlook and whether management has insight into stabilization or recovery.

Director Jedd Gould buys 15,000 GLIBK shares at $34.11; holdings surge to 15,051 from 51 shares (+29411.8%)

Director Jedd Gould executed a substantial open-market purchase of 15,000 shares at $34.11, representing a transformative increase in his position from 51 shares to 15,051 shares post-transaction. The transaction occurred while the company is reporting significant net losses of $-387,000,000 on quarterly revenue of $257,000,000, and the stock has declined 6.7% over 30 days and trades 11.7% below its 52-week high of $38.60. The magnitude of this position increase—a 29411.8% net change—combined with the company's negative earnings picture and recent price weakness, elevates the filing's relevance for investor scrutiny regarding director conviction in current valuations versus fundamental deterioration.

Director Malone buys 763 GLIBK shares at $35.00; fifth consecutive purchase in 9 days; current price $37.27.

John C. Malone, a director, purchased 763 shares of GCI Liberty at $35.00 on 2025-09-26, adding to a holding of 1,221,358 shares. This purchase represents the fifth consecutive buy at GLIBK within a 9-day window (2025-09-17 through 2025-09-26), suggesting sustained accumulation activity. The current market price of $37.27 is 3.4% below the 52-week high of $38.60 and has appreciated 1.7% over the past 30 days. However, none of Malone's prior same-ticker transactions are yet measurable at the 30- or 90-day horizon, and his cross-ticker track record shows an average 30-day return of -1.4% across 20 prior buys, limiting inference about timing accuracy. The pattern reflects sequential purchasing behavior rather than a single conviction trade.

Director John C. Malone bought 2,319 shares (2.3K) at $35.00 for $81,165.00 across two days, raising stake to 1.22M shares.

Director John C. Malone executed two separate purchases totaling 2,319 shares at $35.00 on consecutive days (2025-09-24 and 2025-09-25), investing $81,165.00 and increasing his post-transaction holdings to 1,220,595 shares (+0.2% vs pre-transaction holdings). The current price of $35.19 is within the 52-week range and only marginally above the execution price, with the stock down 5.2% over the past 30 days and 8.8% from its 52-week high. In the same-ticker context, Malone has executed five prior buys at GCI Liberty within the past ten days (2025-09-15 through 2025-09-22), suggesting a pattern of recent accumulation at depressed valuations. His cross-ticker track record shows 20 prior buys with a 100% win rate at the 90-day mark, though this latest same-ticker activity remains immeasurable at current timeframes. The filing itself is routine in scope—a small incremental addition to an already substantial position.

Director Malone buys 10,270 GLIBK shares across 2 transactions for $359,159.05 (blended $34.97); fifth consecutive GLIBK purchase in a week.

MALONE JOHN C filed two separate purchases totaling 10,270 shares for $359,159.05 on 2025-09-18 and 2025-09-22 at a blended average price of $34.97. This represents a 0.9% net increase in his post-transaction holdings of 1,218,276 shares. Notably, this is the fifth GLIBK buy recorded in his open-market history—with four prior GLIBK trades executed between 2025-09-09 and 2025-09-17, all during the same week. The transactions occurred while the stock was trading near its 52-week high, 7.4% below the $38.60 peak and down 7.4% over the prior 30 days. Malone's cross-ticker track record shows 20 prior buys with a 100% win rate on a 90-day horizon, though outcomes for these five consecutive GLIBK trades remain unmeasurable. The concentrated pattern of five purchases within a single week merits close observation as outcomes become available.

Director John C. Malone buys 49,898 shares in 3 tranches ($1,745,691.66) at GLIBK; holdings rise to 1,208,006 shares

John C. Malone, a Director, executed 3 separate purchases of GCI Liberty stock between September 15–17, 2025, acquiring 49,898 shares for $1,745,691.66 at a blended average price of $34.99. His shareholdings increased 4.3% to 1,208,006 shares. At the current price of $35.01, the transaction is nearly at breakeven, and the stock is down 9.3% from its 52-week high of $38.60, suggesting prices were depressed during the purchase window. Malone's cross-ticker track record shows 20 prior open-market buys with a 100.00% 90-day win rate and an average 90-day return of +3.8%, but his 5 most recent purchases at GLIBK (September 2–9, 2025) remain too early to measure outcomes. The clustering of multiple buys within three calendar days, following four additional purchases just one week prior at the same ticker, signals sustained accumulation activity, though the absence of detailed transaction flags and timing context limits definitive interpretation of underlying motivation.

Director Malone purchases 14,169 shares at $35.99 avg across 3 transactions on 2025-09-08/09, accumulating to 1.16M shares (+1.2%)

John C.

His post-transaction holdings of 1,158,108 shares represent a 1.2% increase and reflect sustained accumulation at this ticker: he has executed 5 prior purchases at GLIBK within the past three weeks (August 20 through September 4). Across his broader cross-ticker buy history, Malone's 20 prior open-market purchases averaged +5.4% 30-day returns and +4.6% 90-day returns with a 100.00% win rate, establishing a strong track record of market timing. However, his same-ticker trades at GLIBK are too recent to assess outcomes: all 5 prior purchases have no measurable 30-day or 90-day returns yet, and the timing pattern shows 0 of 0 prior buys at this ticker were well-timed at the 90-day mark. The current purchase takes place with the stock down 6.8% from its 52-week high of $38.60 but up 4.6% over the past 30 days, positioning this accumulation within a recent uptrend.

Malone executed two separate open-market purchases totaling 3,700 shares for $133,200.00 ($36.00 blended average) on 2025-09-02 and 2025-09-04, adding 0.3% to his 1.14M-share position. The timing aligns with strong recent price momentum: GCI Liberty has gained 10.2% over the past 30 days and currently trades at $36.22, above the transaction price. Malone's cross-ticker track record shows 20 prior buys with a 100% 90-day win rate and +4.9% average 30-day return, demonstrating consistent execution on his open-market purchases. At GCI Liberty specifically, Malone has accumulated shares across 5 separate buys since 2025-08-19, though near-term outcomes on those earlier trades remain unmeasurable. The consistent accumulation pattern and recovery to near 52-week-high levels ($38.60) warrant investor attention as a signal from a seasoned insider.

Across his broader open-market history spanning multiple tickers, Malone has executed 20 prior buys with an average 90-day win rate of 100.00% and average 30-day return of +4.9%, though none of his five prior GLIBK trades have yet reached measurable 30- or 90-day outcome windows.

The substantial absolute dollar commitment and significant percentage increase in holdings from a high-net-worth director warrant investor attention to understand the underlying investment thesis and any material information asymmetries the insider may possess.
