This transaction was part of a pre-arranged 10b5-1 trading plan adopted on 2026-03-11, making it scheduled rather than discretionary. The blended average sale price of $385.17 compares to a current price of $380.37, and the stock is -19.8% from its 52-week high of $474.02 while up 11.0% over the prior 30 days and up 33.8% over 90 days. His prior five sales at this same ticker (all on 2025-02-05) occurred in a context where 30-day returns ranged from -37.2% to -39.2% and 90-day returns ranged from -31.7% to -33.9%, providing historical context for this stock's post-sale movement patterns specific to CLS.

CEO Robert Mionis sold 55,768 shares of CLS for $21.6M under 10b5-1 plan (scheduled, not discretionary)

Robert Mionis, Chief Executive Officer of Celestica Inc, executed 15 separate sales totaling 55,768 shares for $21,580,049.91, reducing his holdings from 134,328 to 78,560 shares (a 41.5% reduction in position). This sale is part of a pre-arranged 10b5-1 trading plan adopted on 2026-03-11, making it scheduled rather than discretionary. His prior trades at Celestica show consistent negative 30-day and 90-day returns, with five previous sales on 2025-02-05 all recording losses in both time windows (30-day range -39.2% to -37.2%; 90-day range -33.9% to -31.7%), though this historical pattern is not predictive of this filing's future trajectory given the plan's pre-arranged nature. The stock has risen 11.0% over the past 30 days and 33.8% over 90 days from lower levels, indicating recent momentum despite the CEO's substantial divestiture.

The transaction is part of a pre-arranged 10b5-1 trading plan adopted on 2026-03-11, meaning it was scheduled, not discretionary. The current stock price of $380.37 is 19.8% below the 52-week high of $474.02, though the stock has risen 11.0% over the past 30 days and 33.8% over 90 days. Mionis's prior sales at Celestica (five separate sales on 2025-02-05) all resulted in negative 30-day and 90-day returns, with 90-day declines ranging from -31.7% to -33.9%, and his cross-ticker track record shows an average 90-day return of -31.3% after eight prior sells, though this scheduled sale itself carries no timing characterization.

CEO Robert Mionis sells 75,000 CLS shares for $10.6M across 6 transactions on Feb 5, 2025; stock up 55.2% in 90 days, near 52-week high of $143.67.

The transaction reduced his holdings from 531,417 shares to 456,417 shares, representing a 14.1% reduction. This activity occurred as CLS stock has appreciated substantially—up 55.2% over the past 90 days and currently trading at $133.22, only 7.3% below its 52-week high of $143.67. The timing of this large CEO sale coincides with the stock near its peak performance, which may signal a threshold for reducing exposure at elevated valuations, though the current FACTS section contains no earnings data, material announcements, or disclosed planned trading arrangement that would contextualize the motivation.

CEO Mionis sells 441,325 shares of CLS for $54.0M at $122.28, reducing stake by -45.4%; stock near 52-week high at $143.67.

MIONIS ROBERT sold 441,325 shares (441.3K shares) for $53,965,221.00 ($54.0M) at $122.28 on 2025-02-03, reducing his holdings from 972,742 shares to 531,417 shares—a -45.4% reduction in his position. The sale occurred at a price $21.39 below the current price of $143.67, which sits at the 52-week high. The stock has surged +45.5% over the past 30 days and +68.4% over 90 days, meaning the CEO sold well before this recent acceleration. His SAME-TICKER HISTORY shows 5 prior transactions at CLS, all sells on 2025-02-05 (timing outcomes not yet measurable). The magnitude of this single transaction—$54.0M and nearly half his stake—combined with the stock's subsequent climb to multi-month highs warrants investor attention to whether fundamental or strategic developments drove this reduction.

CEO Robert Mionis sold 52,588 shares of CLS at $127.54 on 2025-01-31; retains 972,742 shares post-sale

Robert Mionis, CEO of Celestica Inc, executed a single open-market sale of 52,588 shares (representing -5.1% of his pre-transaction holdings) at $127.54, totaling $6,707,073.52. The sale occurred near the 52-week high of $123.47 and reflects a reduction in his equity stake from 1,025,330 to 972,742 shares. With minimal cross-ticker track record (1 prior sell) and no measurable outcomes from his one prior CLS transaction, there is insufficient pattern data to assess whether this sale reflects any particular timing acumen. The stock has advanced 24.7% over 30 days and 59.8% over 90 days prior to the transaction, suggesting the CEO executed the sale during a period of substantial recent appreciation.
