IDCC InterDigital, Inc. Insider Trading

CLO Schmidt sold 6,000 shares at $344.35–$355.17 for $2.1M, reducing stake by 18.8% to 25.9K shares

Joshua D. Schmidt, CLO & Corp Secretary at InterDigital, executed 9 separate sales totaling 6,000 shares for $2,089,259.92 on 2026-03-17, realizing an average price of $348.21 per share. The blended execution prices ($344.35–$355.17) cluster tightly in a narrow band, consistent with an orderly execution. Post-transaction holdings of 25.9K shares represent an 18.8% reduction versus the pre-transaction position of 31.9K shares. The current stock price of $351.33 sits near the upper end of the executed range, and the company's recent quarterly net income of $67.5M on revenue of $164.7M reflects profitable operations, though annual revenue growth is negative at -4.0%. The stock is currently -11.4% from its 52-week high of $396.54, suggesting some distance from recent peaks.

CFO Richard Brezski sold 8,005 shares ($2.9M) at InterDigital on Feb 10-11; reduces stake 10.2%, stock up 13.6% in 30 days

Richard Brezski, CFO of InterDigital (IDCC), executed 17 separate sales totaling 8,005 shares for $2,871,101.88 across two trading days (Feb 10-11, 2026), reducing his holdings from 78,408 to 70,403 shares (a -10.2% reduction in position size). The blended average price of $358.66 stands just 0.5% above the current price of $356.83, and notably, the stock has appreciated 13.6% over the 30 days following the sale. His prior five sales at IDCC (all on 2026-01-06) each recorded positive 30-day returns ranging from 3.3% to 9.6%, suggesting a pattern where this insider's recent sales have been followed by price strength rather than weakness. Against a backdrop of flat annual revenue growth (-4.0%), a healthy P/E of 16.82, and continued profitability ($67.5M net income on $164.7M revenue), this large secondary-market liquidation by the CFO may warrant investor attention regarding capital allocation priorities or personal portfolio rebalancing.

CEO Chen Lawrence Liren sold 5,958 shares at $327.62 (blended) for $1,951,977.52 on 2026-01-27 at IDCC

Chen Lawrence Liren, IDCC's President and CEO, executed 6 separate sales totaling 5,958 shares for $1,951,977.52 on 2026-01-27, reducing his holdings by 3.7% from 159.0K to 153.1K shares. The sales occurred across a narrow price range ($324.58–$331.16), with the blended average at $327.62 versus the current price of $331.92. Notably, IDCC trades -16.3% from its 52-week high, while the company reports strong fundamentals—annual revenue growth of +58.0%, net income of $67,503,000.00 on $164,682,000.00 in revenue, and a P/E of 17.20. The insider's cross-ticker track record shows 20 prior sells with an 8.33% well-timed rate (90-day outcomes), but his same-ticker history at IDCC reveals 5 consecutive recent sells (2026-01-07 through 2026-01-21) with no yet-measurable outcomes. The clustering of five sales within two weeks, immediately followed by this sixth transaction, warrants observation for any scheduled trading plan disclosure in SEC filings.

CEO Chen Lawrence Liren sold 5,950 shares of IDCC for $1,875,678.00 across 2 separate sales on 2026-01-20/21 at blended avg $315.24.

Chen Lawrence Liren, President and CEO, executed 2 separate sales totaling 5,950 shares for $1,875,678.00 at an average price of $315.24, reducing his holdings by 3.6% to 159,035 shares. The current stock price of $332.99 sits 16.0% below the 52-week high and has declined 11.0% over the past 90 days, though it is up 0.3% over the past 30 days. Notably, this filing represents the fifth sale by this insider at IDCC in the past 3 weeks (additional sales on 2026-01-14, 2026-01-13, 2026-01-07, and 2026-01-06), suggesting a sustained pattern of liquidation at the executive level, though outcomes on these recent trades are not yet measurable.

CEO Chen Lawrence Liren sold 5,950 shares for $1.9M on 2026-01-13 and 2026-01-14 at InterDigital (IDCC), reducing holdings by 3.5%.

Chen Lawrence Liren, President and CEO of InterDigital, Inc., executed 2 separate sales totaling 5,950 shares for $1,855,031.50 ($1.9M) at a blended average price of $311.77 on January 13–14, 2026. This represents a -3.5% reduction in his post-transaction holdings of 164,985 shares. The company has strong fundamentals: latest quarterly revenue of $164,682,000.00 ($164.7M), net income of $67,503,000.00 ($67.5M), annual revenue growth of +58.0%, and a P/E of 16.20. However, the stock has declined -21.2% from its 52-week high of $396.54 and -10.9% over the past 30 days. Notably, the CEO has executed 4 additional sales at IDCC within the prior week (January 6–7, 2025), and his cross-ticker track record shows prior sells were poorly timed, with an average 90-day return of +5.3% and a well-timed rate of 12.50%. The pattern of frequent sales amid stock weakness warrants monitoring, particularly given the recent trajectory.

IDCC CEO Chen sells 5,950 shares ($1.9M) at $334.08 & $310.47 as stock falls 22% from highs; third consecutive day of sales.

Chen Lawrence Liren, President and CEO, executed 2 separate sales totaling 5,950 shares for $1,917,536.25 over January 6–7, 2026, at blended average price $322.28. The transactions occur as IDCC trades at $309.23 current price, down 22.0% from its 52-week high of $396.54 and down 13.8% over the prior 30 days. Notably, the CEO also sold on 2025-12-31 and 2025-12-30, marking three consecutive trading days of liquidation. At the same-ticker level, his prior three measurable sells at IDCC all resulted in positive 90-day returns (the stock rose after each sale), meaning none were well-timed by sell discipline. His cross-ticker track record shows a 16.67% well-timed rate on prior sells, below a typical insider base-rate. The company fundamentals remain sound—$164.7M latest-quarter revenue with +58.0% annual growth, $67.5M net income, and 16.02 P/E—yet sustained selling by the CEO during a sharp drawdown warrants observation alongside the lack of demonstrated sell-timing accuracy at this ticker.

CFO Brezski sells 11,983 shares of IDCC over two days for $3,928,198.28; stock down 13.8% in 30 days

Richard Brezski, CFO of InterDigital, executed 27 separate sales totaling 11,983 shares (12.0K shares) for $3,928,198.28 ($3.9M) on 2026-01-05 and 2026-01-06, reducing his holdings by 13.3% from 90,355 to 78,372 shares. The blended average price of $327.81 contrasts sharply with the current price of $309.23, and the stock has declined 13.8% over the past 30 days and 22.0% from its 52-week high of $396.54. At the same ticker (IDCC), Brezski's five prior sells in March 2025 each showed negative 30-day returns (ranging from -3.7% to -5.5%), establishing a pattern of selling into subsequent weakness; his 90-day returns on those prior trades all turned positive, suggesting those sales preceded temporary pullbacks. This current sale at elevated prices ($300–$335 range) followed by steep 30-day decline warrants attention to whether broader market or company-specific headwinds are emerging, particularly given InterDigital's strong recent fundamentals (revenue growth +58.0%, P/E 16.02, $67.5M net income).

IDCC CEO Chen Lawrence Liren sold 5,950 shares in 2 transactions for $1,948,149.00, reducing stake by 3.3% as stock trades -19.7% from 52-week high.

Chen Lawrence Liren executed 2 separate sales totaling 5,950 shares on 2025-12-30 and 2025-12-31 at blended average price $327.42, raising $1,948,149.00 and reducing post-transaction holdings to 176.9K shares. The sales occurred as the stock declined -9.5% over 30 days and -10.6% over 90 days, trading at $318.38 currently, representing -19.7% from the 52-week high of $396.54. Historically, his prior trades at IDCC (5 separate sells in March 2025) showed 30-day declines ranging from -8.5% to -11.2%, yet all five generated positive 90-day returns (+5.2% to +8.4%), suggesting these prior sales were poorly timed in hindsight. The timing pattern is factual: 0 of 5 prior same-ticker sells were well-timed at the 90-day mark. The company fundamentals remain solid with annual revenue growth of +58.0%, net income of $67,503,000.00 from latest quarterly revenue of $164,682,000.00, and P/E of 16.50, all consistent with operational strength.

Chief Licensing Officer Eeva K. Hakoranta sold 4,800 shares at blended average $217.92 on 2025-03-19, reducing stake by 14.9%.

Eeva K. Hakoranta, Chief Licensing Officer at InterDigital, executed 3 separate sales totaling 4,800 shares for $1,046,028.96 on 2025-03-19, with a blended average price of $217.92. The sale reduced her holdings from 32,317 to 27,517 shares, a 14.9% reduction. The transaction occurred while the stock traded near its 52-week high of $220.85 (current price $219.14 is -0.8% from the high), and within a 90-day window showing +15.7% appreciation. InterDigital's fundamentals remain robust, with latest quarterly revenue of $128,679,000.00 and annual revenue growth of +58.0%, alongside a P/E of 13.76. The sale represents a material reduction in executive holdings at a price point near historical peaks.

CFO BREZSKI sells 13,250 shares at blended average $213.13 for $2.8M on 2025-03-14; stock near 52-week high at $219.05

Richard Brezski, Chief Financial Officer of InterDigital, executed 7 separate sales totaling 13,250 shares for $2,823,957.59 on 2025-03-14 at prices ranging from $209.64 to $215.82, reducing his post-transaction holdings to 83,451 shares from 96,701 shares (-13.7%). The sales occurred when IDCC was trading near its 52-week high of $219.63, currently at $219.05, and follow a pattern of recent selling activity by the same insider across multiple dates in mid-February 2025. Fundamentals appear solid with annual revenue growth of +58.0%, a P/E of 13.75, and net income of $34,190,000.00 in the latest quarter. The insider's cross-ticker track record shows a 0.00% well-timed sell rate (8 prior sells), meaning prior sales have not been well-positioned relative to subsequent 90-day price movements, making this particular transaction difficult to interpret as a directional signal without additional context.
