CLNN Clene Inc. Insider Trading

Director Matlin buys 33,333 shares at $6.50 in CLNN; stock now -59.2% from 52-week high, down -24.7% in 30 days.

Director David J. Matlin purchased 33,333 shares at $6.50 on 2026-01-13, increasing his holdings from 444,491 to 477,824 shares (+7.5%). The purchase occurs as CLNN trades at $5.10, significantly below the transaction price and down -59.2% from its 52-week high of $12.50, with the stock declining -24.7% over the prior 30 days and -42.6% over 90 days. Across his prior two purchases at CLNN specifically, Matlin demonstrated strong timing at the 90-day mark (returning +5.0% and +1937.6% respectively), establishing a pattern of well-timed accumulation at this ticker. However, the company's fundamentals are severely deteriorated: revenue collapsed -47.7% year-over-year, the latest quarter shows just $15.0K in revenue with a net loss of $-8.8M, and the company remains unprofitable. The purchase against this backdrop—after substantial recent price declines—presents a test of whether Matlin's historical timing acumen extends into a sharply weakened operational environment.

10% Owner Ugwumba Chidozie sells 257,795 shares over 12 days for $1,725,734.59; stock down 29.4% in 30 days, 47.7% revenue decline, unprofitable.

Ugwumba Chidozie, a 10% owner of Clene Inc., executed 12 separate sales totaling 257,795 shares for $1,725,734.59 between December 3–18, 2025, reducing his stake by 39.6% from 650,945 shares to 393,150 shares. The sales span a declining price ladder from $7.86 to $5.70 (low) and back to $6.33, with a blended average of $6.69 against a current price of $6.04. The timing is significant: the stock has fallen 29.4% in the 30 days preceding and during this filing window and trades 51.7% below its 52-week high of $12.50. Clene's fundamentals are deteriorating—revenue dropped 47.7% year-over-year to only $15,000.00 in the latest quarter, the company posted a net loss of $8,777,000.00, and it remains unprofitable on a full-year basis. While Chidozie's cross-ticker track record shows strong prior returns (90d win rate 100%, avg 90d return +1397.5%), his one prior trade at CLNN (a buy on June 16, 2023) returned +1900.2% over 90 days—a pattern that does not apply here, as he is now selling into a declining equity amid material operational challenges. The scale of this position reduction and the compressed timeframe warrant close attention to whether further insider activity or company guidance changes follow.

Director MATLIN DAVID J buys 92,307 shares of CLNN at $4.75; holdings +26.2%; cluster pattern with 2 other insiders buying within 14 days.

Director MATLIN DAVID J purchased 92,307 shares at $4.75, increasing his holdings by 26.2% to 444,491 shares. The transaction occurs within a cluster: 2 other insiders also bought within the past 14 days, suggesting coordinated confidence at this price level. At CLNN specifically, his prior buy on 2023-11-10 returned +1797.6% over 90 days, indicating a track record of well-timed accumulation at this ticker. The current stock trades at $4.89, -55.1% from its 52-week high of $10.90, creating a valuation backdrop that may have motivated this director-level accumulation. The company remains unprofitable (net income $-6.8M in the latest quarter) with minimal quarterly revenue ($91.0K), but shows annual revenue growth of +38.3%, leaving fundamental trajectory uncertain and making insider conviction—expressed through significant share increase—a notable signal for investors to track.

CEO Etherington buys 10,000 CLNN shares at $4.75 as stock down 29.8% in 90 days; 2 other insiders also bought in 14-day cluster.

Robert Dee Etherington, Chief Executive Officer of Clene Inc., purchased 10,000 shares at $4.75 on 2024-09-30, bringing his holdings to 40,149 shares (a 33.2% increase). The transaction occurs in a downtrend: the stock is -57.8% from its 52-week high and down 29.8% over the past 90 days. Notably, two other insiders also bought within the past 14 days, forming a cluster buy pattern at depressed prices. Etherington's prior buy at CLNN on 2023-06-26 delivered 90-day returns of +1043.2%, suggesting his timing instinct at this ticker has been accurate in the past, though that historical outcome does not guarantee future performance. The company remains unprofitable (full-year net income was negative) despite 38.3% annual revenue growth, and current market cap stands at $29.8M. This multi-insider accumulation during a sustained selloff warrants attention to whether management sees value misalignment or anticipates a business inflection.

Clene CSO Mortenson bought 20,512 shares at $4.75 (Sept 30); cluster pattern: 2 other insiders bought within 14 days

Mortenson purchased 20,512 shares at $4.75 on 2024-09-30, expanding his holdings from 8,437 to 28,949 shares—a 243.1% increase in position size. The transaction occurred as the stock traded 57.8% below its 52-week high of $10.90 and has declined 29.8% over the past 90 days. Notably, 2 other insiders also purchased shares within the same 14-day window, forming a cluster buy pattern. However, the company remains unprofitable with a net income of $-6.8M over the latest full fiscal year, and near-term revenue of $91.0K in the latest quarter raises questions about business momentum despite 38.3% annual revenue growth.
