PLXS PLEXUS CORP Insider Trading

Regional President of APAC sells 3,000 shares (22% of holdings) at $271.23 per share, marking third open-market sale in 36 months.

Victor Tan, Regional President for APAC, sold approximately one-fifth of his shareholding in this transaction, marking his third open-market sale at Plexus in the past 36 months and his 12th open-market sale across all holdings during that period. The stock is currently trading modestly below its 52-week high after a substantial rally, having gained significantly over the prior quarter. Notably, his prior two sales at this company were well-timed exits over a 30-day horizon as the stock subsequently declined, though both sales ultimately proved poorly timed on a 90-day view as shares recovered. Plexus remains profitable with solid revenue, though the latest quarter showed year-over-year revenue contraction and shares trade at a relatively elevated valuation multiple, suggesting the company faces near-term headwinds despite its profitability. This sale adds to a pattern of regular dispositions by this insider rather than any fresh accumulation.

EVP Angelo Ninivaggi Jr. sold 5,568 shares ($1.47M) across six transactions while PLXS trades near 52-week highs and remains profitable with growing revenue.

Angelo Ninivaggi Jr., Executive Vice President and Chief Legal Officer, executed six separate sales over two trading days totaling approximately $1.47 million in aggregate proceeds. The sales occurred while the stock was trading near its 52-week high and has surged significantly over the past quarter, placing Ninivaggi's dispositions near a peak valuation point. Plexus remains a profitable, revenue-growing business with a substantial market capitalization, so this sale does not signal financial distress at the company level. However, Ninivaggi has now completed 21 open-market sales over the past 36 months with zero open-market purchases during that span, establishing a clear pattern of consistent net reduction in his holdings—this is his 16th through 21st sale in that window. The combination of the sale size, senior officer rank, sustained selling pattern, and timing near 52-week highs warrants observation, though the lack of other insider activity in a recent cluster and the company's solid fundamentals prevent this from rising to an urgent alert.

PLXS CEO sells ~6,400 shares across three days totaling $1.71M near 52-week highs.

Kelsey Todd P., PLXS's President and CEO, executed a series of sales totaling approximately $1.71 million in company shares across a three-day window, liquidating modest single-digit percentages of holdings. The sales occurred with the stock trading right at its 52-week peak after a sustained rally, presenting a striking contrast to Todd's historical pattern: across 20 prior trades, she has never purchased a single share—only sold. Her previous sales in this same stock show mixed timing: while some saw the stock appreciate meaningfully in the months following, suggesting she may have exited too early, her track record overall lacks the consistent conviction that would come from well-timed exits. A profitable company with solid revenue growth does not automatically justify selling at historical highs, and the CEO's willingness to trim positions right at the peak warrants monitoring for potential near-term pullback risk.

PLXS CEO Kelsey Todd P. sells 5,231 shares for $1,024,111.56 at blended avg $195.78, retaining 83,291 shares post-sale.

Kelsey Todd P. conducted 3 separate sales on 2026-02-18, totaling 5,231 shares for $1,024,111.56, reducing his holdings by -5.9%. The blended average sale price of $195.78 is 0.4% below the current price of $196.57, indicating execution near current market levels. In his cross-ticker track record (20 prior sells across all holdings), the insider's 90-day return averaged +6.4% and he achieved well-timed exits on 56.25% of those sells—suggesting a mixed pattern of timing success. However, at PLXS specifically, his single measurable prior sale (2025-11-05) resulted in a +40.4% 90-day return, indicating the stock rose significantly after that exit. The current stock price is +11.8% over the past 30 days and +42.0% over 90 days, reflected in the 30.76 P/E and proximity to the 52-week high of $208.36. With annual revenue growth of -1.1% and net income at $41.2M against quarterly revenue of $1,069,852.00, the company shows mixed operational momentum. The pattern of recent activity—including 4 additional sells on 2026-02-03, also on this Form 4—warrants attention to whether systematic liquidation is underway.

PLXS COO Mihm Oliver K. sold 11,767 shares over 2 days (Feb 17-18) for $2.4M; prior PLXS sells were well-timed at 90 days

Mihm Oliver K., Exec VP & COO of Plexus Corp, executed 2 separate sales totaling 11,767 shares for $2,364,052.81 at blended average price $200.91, reducing his holdings by 47.9% from 24,576 shares to 12,809 shares. This represents a material reduction in his personal stake during a period of significant price appreciation: the stock has gained 11.8% over 30 days and 42.0% over 90 days, currently trading at $196.57 versus transaction prices near $200.91. Notably, his prior trades at this ticker (2 sales in November 2024) both exhibited negative 90-day returns (-0.0% and -0.9% at 30 days; -14.0% and -16.0% at 90 days), indicating a timing pattern where his sales preceded subsequent stock declines. The current transaction occurred after substantial recent gains, and the stock is now 5.7% below its 52-week high of $208.36, creating a factual pattern worth monitoring against his demonstrated accuracy in prior PLXS sales timing.

Director Dean Foate sells 10,000 PLXS shares at $205.00; stock near 52-week high ($208.36) after +40.9% 90-day surge

Director Foate sold 10,000 shares (-9.1% of pre-transaction holdings) at $205.00 on 2026-02-06, just days after a prior sale on 2026-02-02. The stock is currently trading at $206.00, near its 52-week high of $208.36, having surged +40.9% over 90 days and +30.6% over 30 days—significantly outpacing the insider's cross-ticker track record, which shows an average 90-day return of -16.2% following his prior sales. Notably, at this specific ticker (PLXS), the insider's prior three measurable sales (November 2024) all preceded declines of approximately 15-16% by the 90-day mark, achieving a 100% well-timed rate at this ticker. The current sale occurs during the stock's strongest momentum period, following a steep rally from a 52-week low of $110.95, which contrasts sharply with his historical pattern of selling ahead of downturns.

PLXS Regional President Tan Victor sold 3,000 shares for $616,500.00 on 2026-02-06 at blended $205.50

Tan Victor (Regional President - APAC) executed two separate sales on 2026-02-06, offloading 3,000 shares at $205.00 and $205.75, reducing holdings by 20.8% from 14,435 to 11,435 shares. The sales occurred near the 52-week high of $208.36 (currently $206.00), with the stock up 30.6% over 30 days and 40.9% over 90 days following a recent sharp rally. At a P/E of 32.24 and market cap of $5.5B, valuation is elevated relative to the fundamentals: annual revenue growth sits at -1.1% and latest quarterly revenue was $1,069,852.00. The magnitude of the reduction and proximity to 52-week highs during a strong recent run-up merit monitoring for pattern consistency with this insider's prior activity at this ticker.

CFO Jermain Patrick John sells 3,587 shares of PLXS at $204.09; holds 16,882 shares post-transaction.

Jermain Patrick John, serving as Executive Vice President & CFO, sold 3,587 shares on 2026-02-04 at $204.09 for a total value of $732,070.83, reducing his holdings from 20,469 shares to 16,882 shares, a reduction of 17.5%. The sale occurred near the stock's 52-week high of $206.22, after the stock appreciated 33.0% over the prior 30 days and 44.0% over the prior 90 days. Looking at his prior trades at PLXS, 4 of 5 measurable same-ticker sales show mixed outcomes—two were followed by 90-day gains (+2.6% and +11.8%, +12.4%, +6.5%), while one showed a small 90-day loss (-1.6%)—with none classified as well-timed. His cross-ticker track record shows 8 prior sells with an average 90-day return of +13.5% and a 0.00% well-timed rate, indicating his sales historically have been poorly timed (stock typically rose afterward). The current P/E of 32.27 and recent annual revenue decline of -1.1% provide context for the company's valuation, though the sale size relative to his remaining position of 16,882 shares and the timing near the 52-week high merit monitoring.

Director FOATE DEAN A sold 5,000 shares of PLXS at $204.89 on 2026-02-02 (near 52-week high); prior 3 sales well-timed with 90d declines.

FOATE DEAN A sold 5,000 shares at $204.89, which represents -4.2% from the 52-week high of $204.96 and occurs during a strong recent rally (+27.7% in 30 days, +36.8% in 90 days). The director retains 109,429 shares post-transaction. His cross-ticker track record shows a 100.00% well-timed rate across 3 prior sells (avg 90d return -16.2%), and his same-ticker history at PLXS demonstrates all 3 prior sales were well-timed at the 90-day mark with negative returns (-0.8%, -1.2%, -1.9% at 30 days and -16.4%, -15.8%, -16.4% at 90 days). The sale near the 52-week high, following a period of significant appreciation, combined with a consistent pattern of selling at inflection points, warrants investor attention to whether this marks a shift in momentum for the stock.

PLXS President & CEO Kelsey Todd P. sells 8,120 shares for $1,669,879.95 at $205.65 avg, retaining 78,598 shares

Kelsey Todd P. executed 4 separate sales totaling 8,120 shares for $1,669,879.95 on 2026-02-03 at a blended average price of $205.65, reducing holdings by 9.4% to 78,598 shares. The sale occurred as PLXS trades at $203.78, just 0.6% below its 52-week high of $204.96, amid strong recent momentum: the stock has gained 33.9% over 30 days and 40.1% over 90 days. At the same-ticker level, Todd P.'s most recent prior sells (November 2025) were well-timed: the subsequent 90-day periods showed gains of 40.4% and 42.8%, indicating the stock continued rising after those sales. However, his cross-ticker track record shows average 90-day returns of +10.0% after sells (an average well-timed rate of 45%, meaning his sells historically have not captured downturns effectively), and his earlier sales at PLXS in February 2025 were poorly timed, with 90-day declines of -7.4% and -5.6% following those transactions. This sale at a price near the 52-week peak, concurrent with elevated stock momentum, merits observation for subsequent price action and alignment with forward earnings visibility.
