COO Daniel Giesecke sells 20,201 shares at $37.32-$37.33 via scheduled 10b5-1 plan; retains 175,855 shares post-transaction

Daniel J. Giesecke, Senior Vice President & COO, executed 2 separate sales totaling 20,201 shares for $753,903.09 under a pre-arranged 10b5-1 trading plan adopted on 2026-02-25. His holdings decreased from 196,056 to 175,855 shares, representing a 10.3% reduction in his position. The sale occurred as the stock traded near its 52-week high of $38.40, with the company reporting recent quarterly revenue of $153,100,000 and net income of $9,700,000, though the P/E of 57.74 reflects a relatively elevated valuation. The scheduled nature of this transaction removes discretionary timing as a signal factor.

Significance 5

CEO Niew Jeffrey executes matched buy-sell of 142,857 shares; stock near 52-week highs after sharp recent rally.

Niew Jeffrey, President and CEO of Knowles Corp, executed a same-day purchase and sale of identical share quantities—buying at a lower price and immediately selling at a significantly higher price on May 5th. This is fundamentally a financial transaction rather than a shift in conviction about the company. The stock is currently trading near its 52-week high and has rallied substantially over the past three months, yet the CEO's prior sales history shows mixed timing results: while recent sales have been followed by further stock appreciation over the following 90 days, indicating poor exit timing, the shorter 30-day windows show much more modest moves. The company remains profitable with steady revenue growth, though it trades at a notably elevated valuation multiple. This matched buy-sell structure—locking in a gain between the two prices in a single day—is a mechanical transaction that does not reflect the same conviction signal as a straight purchase or sale would, and investors should view it as such rather than as a bullish or bearish statement about Knowles' prospects.

Significance 6

Director Keith Barnes sold 41,048 shares of Knowles Corp (KN) at $27.16 on 2026-02-19, completely exiting his position.

Keith Barnes, a director, executed a complete liquidation of his Knowles Corp holdings, selling 41,048 shares for $1,114,863.68 at $27.16 per share, leaving zero shares post-transaction. The transaction occurred near the stock's 52-week high of $28.07 (within 0.0% of peak), and follows a 30-day price surge of +17.2% and 90-day appreciation of +25.0%. Notably, Barnes's cross-ticker track record shows 2 prior sales with an average 90-day return of +45.0% and a well-timed rate of 0.00%, indicating his historical sells have generally missed subsequent upside; however, this current sale near the 52-week high represents a significant departure from that pattern. The company's fundamentals show solid performance: $152.9M quarterly revenue with +7.2% annual growth and a low P/E of 7.37 at a $2.4B market cap.

CFO Anderson John S. sells 25,000 shares ($677,080.78) at blended $27.08; stock up 16.7% in 30 days, 23.4% in 90 days.

Anderson John S., Senior Vice President & CFO of Knowles Corp, executed 2 separate sales totaling 25,000 shares for $677,080.78 at a blended average price of $27.08 on 2026-02-10, reducing his holdings by 11.9% from 210.7K to 185.7K shares. The stock is currently at $27.00, just 0.9% below its 52-week high of $27.24, and has appreciated 16.7% over the past 30 days and 23.4% over 90 days. His prior 3 sales at KN (all on 2025-11-21) showed positive 30-day returns of 5.8%, 6.3%, and 2.8%, indicating the stock continued to rise after those sales. With the company trading at a P/E of 7.09 on $152.9M quarterly revenue and $2.3B market cap, the sale represents a substantial reduction of insider holdings at a price near the 52-week peak, occurring during a period of strong recent stock appreciation.

Knowles CEO Jeffrey Niew sells 75,000 shares for $1,987,500.00 under pre-arranged 10b5-1 plan

Jeffrey Niew, President & CEO of Knowles Corp, executed 3 separate sales totaling 75,000 shares for $1,987,500.00 on 2026-02-06 at prices ranging from $26.00 to $27.00. This sale was conducted under a pre-arranged 10b5-1 trading plan adopted on 2025-08-13, meaning it was scheduled rather than discretionary. Post-transaction, Niew retains 739,370 shares, representing a 9.2% reduction from his pre-transaction holdings of 814,370 shares. As a scheduled disposition under a 10b5-1 plan, this transaction reflects a predetermined commitment rather than a real-time market timing decision by the CEO.

Significance 3

CEO Jeffrey Niew sold 25,000 shares of KN at $25.50 via pre-arranged 10b5-1 plan adopted 2025-08-13.

President & CEO Jeffrey Niew sold 25,000 shares (25.0K shares) of Knowles Corp for $637,500.00 on 2026-02-03 as part of a pre-arranged 10b5-1 trading plan adopted on 2025-08-13. This represents a -3.0% reduction in his holdings, bringing post-transaction shares to 814,370 (814.4K shares) from 839,370 (839.4K shares) pre-transaction. Because this sale is scheduled under a Rule 10b5-1 plan rather than discretionary, it reflects a pre-set execution schedule rather than a contemporaneous trading decision. The reduction in CEO holdings is modest in percentage terms, and the pre-arranged nature of the plan limits what can be inferred about current sentiment toward the stock.

KN CEO Niew sells 50,000 shares in 2 tranches for $1,237,500.00; stock up 8.7% in 30d but revenue down 21.8% YoY

President & CEO Niew Jeffrey executed 2 separate sales totaling 50,000 shares for $1,237,500.00 at an average price of $24.75, reducing his holdings by 5.6% to 839,370 shares. The sales occurred after a strong 30-day rally of 8.7%, yet Knowles Corp faces significant operational headwinds: annual revenue declined 21.8%, the company posted negative full-year net income, and the stock trades at a 49.06 P/E despite $152.9M in latest-quarter revenue. His prior sales at this ticker show a mixed pattern, with only 1 of 5 prior trades well-timed at the 90-day mark, though his broader cross-ticker track record shows 100% well-timed sales. The timing of this sale after a near-term rally coincides with deteriorating fundamentals, though the absence of a 10b5-1 plan disclosure in this filing precludes any assertion about whether the transaction was discretionary.

CEO Jeffrey Niew sold 25,000 shares (25.0K) of KN at $24.00 on 2025-12-10 for $600,000.00 (600.0K); stock now at $22.88.

Jeffrey Niew, President & CEO, sold 25,000 shares at $24.00 on 2025-12-10, a 2.7% reduction in holdings that generated $600,000.00. The sale occurred near the 52-week high of $24.41 (only 1.7% below), yet the stock has since declined to $22.88, down 6.3% from the high. His prior trades at KN show a mixed pattern: 1 of 1 measurable 90-day outcomes resulted in post-sale declines (well-timed on 2024-11-06 with a -2.4% 90d return), while three recent sells (2025-10-31, 2025-11-03, 2025-12-04) have shown or are showing negative 30-day returns. The company faces headwinds: annual revenue contracted 21.8% year-over-year and full-year net income was negative despite positive recent quarterly earnings of $17.4M on $152.9M revenue. The elevated P/E of 46.69 on a valuation basis troubled by prior-year losses contrasts sharply with the CEO's execution pattern at this ticker, where his sales have aligned with subsequent price weakness.

CEO Jeffrey Niew sold 25.0K KN shares at $23.50 on 2025-12-04; holds 914.4K shares post-trade.

Jeffrey Niew (President & CEO) sold 25,000 shares valued at $587,500.00, reducing his holdings by 2.7% to 914,370 shares. The sale occurred near the 52-week high ($24.41), with current price $23.42 only 0.3% below the transaction price. Across his full cross-ticker open-market history, Niew's 3 prior sells achieved a 100.00% well-timed rate at the 90-day mark, though his average 90d return of -2.4% signals modest predictive value; same-ticker at KN, only 1 of 1 measurable 90d outcomes was well-timed (the 2024-11-06 sale fell -2.4% over 90 days), while his two most recent KN sales remain unmeasured beyond 30 days. The underlying company faces structural headwinds: annual revenue contracted -21.8% year-over-year, the company was unprofitable over its most recent full fiscal year, and the P/E ratio of 47.80 reflects elevated valuation relative to earnings. The sale pattern—three KN dispositions in 34 days (2025-10-31, 2025-11-03, 2025-12-04)—warrants monitoring against forward guidance and quarterly results.

Significance 5

CFO Anderson sells 30,000 shares (12.1% of holdings) across 3 transactions for $632,000 at blended avg $21.07

Anderson John S., Senior Vice President & CFO, executed 3 separate sales totaling 30,000 shares for $632,000.00 on 2025-11-21, reducing his holdings from 247,299 shares to 217,299 shares. The sales occurred at prices of $20.90, $20.80, and $21.50, with a blended average price of $21.07, near the current price of $21.34. The company is reporting material headwinds: revenue declined 21.8% year-over-year, the firm was unprofitable over its most recent full fiscal year, and the stock is trading at a high P/E of 43.55 with a current price 12.6% below its 52-week high. The magnitude of this sale (12.1% of pre-transaction holdings) in a deteriorating business environment warrants attention to whether this reflects the CFO's assessment of fundamental risk.
