Richard Adam Norwitt (then-CEO) sells 130,775 shares at avg $143.06 for $18.7M; holds 2,786,567 derivative shares

Richard Adam Norwitt, who was President & CEO at the time, executed 3 separate sales totaling 130,775 shares for $18,709,065.94 between May 1–5, 2026, at prices ranging from $142.04 to $143.90 versus a current price of $153.80. His non-derivative holdings fell 6.4% from 2,058,282 to 1,927,507 shares post-transaction, while derivative holdings (stock options across three accounts) total 2,786,567 shares, representing his substantial long-term position in the company. Across his prior open-market sales history, his 90-day well-timed rate is 62.50%, and at this same ticker, 4 of 5 prior sells generated negative 90-day returns—a pattern suggesting historical precision in exits. This month's sales occurred during a 30-day run of +23.4% appreciation and within 7.9% of the 52-week high of $167.04, creating context for evaluation of the timing and intent of the transactions.

Sr. VP/General Counsel D'Amico sells 100,000 APH shares ($6.6M) at $65.63; reduces holdings -66.1% to 51.4K

D'Amico, Amphenol's Sr. VP, Secretary & General Counsel, executed a substantial sale of 100,000 shares worth $6,563,040.00 on 2024-08-15, reducing his holdings from 151,400 shares to 51.4K shares—a -66.1% decline in stake. This represents his largest single transaction relative to remaining position and follows a pattern: his prior trades at APH (3 of 3 measurable sells) posted 90-day returns of -51.4%, -51.4%, and -39.6%, all negative, and his cross-ticker track record across 4 prior sells shows a 100.00% well-timed rate at the 90-day mark with average 90d return of -49.7%. The current price of $65.80 is only -6.6% below the 52-week high of $70.41 and the stock has moved +2.5% in the trailing 30 days, indicating the sale occurred near a peak in recent pricing. The fundamental context shows a mature business (P/E 37.60, $3.6B revenue, -0.5% annual growth) where the transaction occurs at relatively strong valuation levels.

Doherty sells entire 300.0K APH stake for $19.7M; prior 3 sales at APH averaged -47.6% 90d return with 100% well-timed rate

William J Doherty, President of CS Division, executed a complete liquidation of his 300,000 share position in Amphenol at $65.83 on 2024-08-15, exiting a holding that represented 100% of his disclosed APH shares. His track record at this specific ticker is notably consistent: all 3 prior sales show substantially negative 90-day returns (−46.5%, −46.5%, −52.6%), with a 90-day well-timed rate of 100.00%, indicating his recent sells have preceded stock declines. Against current price of $65.80 (−6.6% from the 52-week high of $70.41), this pattern suggests a history of successfully identifying inflection points, though the stock's recent 30-day appreciation of +2.5% creates tension with the broader directional signal. The presence of substantial recent institutional ownership, a P/E of 37.60, and flat annual revenue growth (−0.5%) provide context for why an executive with this timing record would exit completely.

CFO Lampo Craig A sold 250,000 APH shares (53.4% of holdings) for $16.3M at $65.01; exits during 52-week highs

CFO Lampo Craig A executed a substantial open-market sale of 250,000 shares on 2024-08-14 at $65.01, reducing his holdings by 53.4% to 218,116 shares and generating $16,251,825.00. The transaction occurs near the stock's 52-week highs (current price $66.05 is 6.2% below the $70.41 52-week high reached recently), and his cross-ticker track record demonstrates a 100.00% well-timed rate on prior sells with average 90-day returns of -47.0%, indicating a pattern of selling before subsequent declines. At Amphenol specifically, his prior two sales (2024-02-08 and 2023-07-28) both resulted in negative 90-day returns of -39.5% and -54.5% respectively, suggesting consistent timing effectiveness on this ticker. The combination of substantial position reduction, elevated valuation context (P/E 37.74), and a documented pattern of well-timed exits warrants investor attention to potential forward signals.

CEO Richard Norwitt sells 400,000 shares (17.1% of holdings) at $64.28; stock down 11.8% from highs, P/E at 35.50.

Richard Adam Norwitt, President & CEO of Amphenol, executed a $25.7M sale of 400,000 shares at $64.28 on July 31, 2024, reducing his holdings from 2.33M to 1.93M shares. The sale occurs after the stock has declined 8.0% in the prior 30 days and 11.8% from its 52-week high of $70.41, with the company trading at a P/E of 35.50 on annual revenue growth of -0.5%. His cross-ticker track record shows 2 prior sells with an average 90-day return of -54.1% and a 90-day well-timed rate of 100%, and his prior sale at APH on July 28, 2023 was followed by a -54.1% 90-day return. This transaction, arriving just five days after another APH sale on July 26, occurs during a period of recent price weakness and follows a consistent pattern of the insider's prior exits preceding stock declines.

D'AMICO LANCE E sold 90,000 (90.0K shares) APH at $64.65; post-transaction holdings 51,400 (51.4K shares), down 63.6%

D'AMICO LANCE E, Sr. VP, Secretary & General Counsel, executed a substantial sale of 90,000 shares at $64.65 on 2024-07-26, reducing his holdings from 141,400 to 51,400 shares—a 63.6% reduction in his position. Historically, this insider's three prior sales at APH each delivered negative 90-day returns: -39.6%, -54.8%, and -54.8%, establishing a consistent timing pattern where he sold before subsequent declines (100% well-timed rate across these three trades). Current price is $61.94, down 8.1% over 30 days and down 12.0% from the 52-week high of $70.41, suggesting the transaction may be tracking toward another well-timed outcome. Against this backdrop, a company with flat revenue growth (-0.5% year-over-year) and a P/E of 35.39 warrants observation, especially given this senior officer's demonstrated ability to exit before market weakness.

Amphenol President Walter Luc sells 276,000 shares for $17.7M across two transactions, reducing holdings by 38.1%

Walter Luc (President, HES Division) executed 2 separate sales totaling 276,000 shares for $17,700,821.80 (blended average $64.13) on 2024-07-26 and 2024-07-29, reducing his stake from 723,790 shares to 447,790 shares (a 38.1% reduction). The current price of $61.94 is now 12.0% below the 52-week high of $70.41 and 8.1% lower over the past 30 days, placing the execution within a recently declining market. Luc's cross-ticker track record shows 3 prior sells with an average 90-day return of -54.1% and a 90% well-timed rate, indicating his prior sales have consistently preceded stock declines. At the same ticker (APH), his prior 2024 sales on 2024-05-23 and 2024-05-22 showed 30-day declines of -49.3% and -49.1%, respectively, and his 2023-07-28 sale showed a 90-day decline of -54.1%—a pattern of sales before sustained downward moves. The stock's -0.5% annual revenue growth and elevated P/E of 35.39 suggest a valuation-intensive context where insider liquidation of this magnitude warrants investor attention.

CEO Richard Norwitt sold 750,000 shares of APH at $64.54 for $48.4M, reducing stake by 27.9% to 1.93M shares.

Richard Norwitt, as President & CEO, executed a material reduction of his Amphenol stake, divesting 750,000 shares at $64.54 on 2024-07-26 and retaining 1,934,848 shares post-transaction. At the transaction price of $64.54, the stock was trading near the 52-week high of $70.41 (within ~8% of the peak), though it has since retreated to $61.94 (-12.0% from the 52-week high and -8.1% over 30 days). Within his cross-ticker trade history, Norwitt's prior sell at this same ticker (APH on 2023-07-28) showed -50.6% and -54.1% returns at the 30- and 90-day marks respectively, with a 100.00% well-timed rate on all prior sells, indicating a historical pattern of selling before declines. The company itself shows modest fundamentals: flat annual revenue growth (-0.5%), a high P/E of 35.39, and a $74.6B market cap, suggesting current valuations may already reflect elevated expectations. This large discretionary sale by the CEO warrants investor attention as both an indicator of conviction at that price point and as a data point in assessing whether management sees sufficient value at current levels to remain heavily invested.
